    Shah, Naseem; Bansal, Nikhil; Logani, Ajay

    2014-01-01

    Dentistry has witnessed tremendous advances in all its branches over the past three decades. With these advances, the need for more precise diagnostic tools, specially imaging methods, have become mandatory. From the simple intra-oral periapical X-rays, advanced imaging techniques like computed tomography, cone beam computed tomography, magnetic resonance imaging and ultrasound have also found place in modern dentistry. Changing from analogue to digital radiography has not only made the process simpler and faster but also made image storage, manipulation (brightness/contrast, image cropping, etc.) and retrieval easier. The three-dimensional imaging has made the complex cranio-facial structures more accessible for examination and early and accurate diagnosis of deep seated lesions. This paper is to review current advances in imaging technology and their uses in different disciplines of dentistry. PMID:25349663

    Advancements in the field of implantology such as three-dimensional imaging, implant-planning software, computer-aided-design/computer-aided-manufacturing (CAD/CAM) technology, computer-guided, and navigated implant surgery have led to the computerization of implant-dentistry. This three-dimensional computer-generated implant-planning and surgery has not only enabled accurate preoperative evaluation of the anatomic limitations but has also facilitated preoperative planning of implant positions along with virtual implant placement and subsequently transferring the virtual treatment plans onto the surgical phase via static (guided) or dynamic (navigated) systems aided by CAD/CAM technology. Computerized-implant-dentistry being highly predictable and minimally invasive in nature has also allowed implant placement in patients with medical comorbidities (e.g. radiation therapy, blood dyscrasias), in patients with complex problems following a significant alteration of the bony anatomy as a result of benign or malignant pathology of the jaws or trauma and in patients with other physical and emotional problems. With significant achievements accomplished in the field of computerized implant-dentistry, attempts are now been made toward complete automation of implant-dentistry. PMID:25810585

    2015-07-01

    Use of ceramics and polymers continues to dominate clinical procedures in modern dentistry. Polymers have provided the basis for adhesives, tissue void fillers, and artificial replacements for whole teeth. They have been remarkably effective in the clinic at restoration of major dental functions after damage or loss of teeth. With the rapid development of polymer science, dental materials science has significantly lagged behind in harnessing these advanced polymer products. What they offer is new and unique properties superior to traditional polymers and crucially a range of properties that more closely match natural biomaterials. Therefore, we should pursue more vigorously the benefits of advanced polymers in dentistry. In this review, we highlight how the latest generation of advanced polymers will enhance the application of materials in the dental clinic using numerous promising examples. Polymers have a broad range of applications in modern dentistry. Some major applications are to construct frameworks that mimic the precise structure of tissues, to restore tooth organ function, and to deliver bioactive agents to influence cell behavior from the inside. The future of polymers in dentistry must include all these new enhancements to increase biological and clinical effectiveness beyond what can be achieved with traditional biomaterials.

    2010-01-01

    Scientific advances in the creation of restorative biomaterials, in vitro cell culture technology, tissue engineering, molecular biology and the human genome project provide the basis for the introduction of new technologies into dentistry. This review provides an assessment of how tissue engineering, stem cell, genetic transfer, biomaterial and growth factor therapies can be integrated into clinical dental therapies to restore and regenerate oral tissues. In parallel to the creation of a new field in general medicine called "regenerative medicine," we call this field "regenerative dentistry." While the problems of introducing regenerative therapies are substantial, the potential benefits to patients and the profession are equally ground-breaking. In this review, we outline a few areas of interest for the future of oral and dental medicine in which advancements in basic science have already been adapted to fit the goals of 21st century dentistry.

    Childhood oral disease is a significant health problem, particularly for vulnerable populations. Since a major focus of General Dentistry Program directors is the management of vulnerable populations, we wanted to assess their attitudes regarding the inclusion of physicians in the prevention, assessment, and treatment of childhood oral disease. A survey was mailed to all General Practice Residency and Advanced Education in General Dentistry program directors (accessed through the ADA website) to gather data. Spearman's rho was used to determine correlation among variables due to nonnormal distributions. Overall, Advanced General Dentistry directors were supportive of physicians' involvement in basic aspects of oral health care for children, with the exception of applying fluoride varnish. The large majority of directors agreed with physicians' assessing children's oral health and counseling patients on the prevention of dental problems. Directors who treated larger numbers of children from vulnerable populations tended to strongly support physician assistance with early assessment and preventive counseling.

    RENO (Reactor Experiment for Neutrino Oscillation) is an experiment to measure the smallest neutrino mixing angle theta θ₁₃ using electron antineutrinos emitted from the Yonggwang (now Hanbit) nuclear power plant in Korea. Antineutrinos from six 2.8 GW{sub th} reactors are detected and compared by two detectors located at 294 m and 1384 m, respectively, from the reactor array center. Based on 402 days of data taken between 11 August 2011 and 13 October 2012, the ratio of observed to expected numbers of antineutrino at the far detector is 0.929 ± 0.006(stat.) ± 0.009(syst.). From the deficit, we determine sin²2θ₁₃=0.100±0.010(stat)±0.015(syst), 5.6σ significant signal, based on a rate only analysis.

    For children to receive needed oral health care, adequate training at both the predoctoral and postdoctoral levels of dental education is required, but previous studies have found inadequacies in predoctoral education that lead to general dentists' unwillingness to treat certain young populations. As another way of assessing predoctoral preparation, the aim of this study was to determine the perspectives of first-year residents and pediatric program directors about residents' preparedness to enter advanced education programs in pediatric dentistry. Surveys were sent to all 74 U.S. program directors and 360 first-year residents. The survey focused on procedures related to prevention, behavior management, restorative procedures, pulp therapy, sedation, and surgery, as well as treating patients funded by Medicaid and with special health care needs. Among the first-year residents, 173 surveys were returned for a 48% response rate; 61 directors returned surveys for an 82% response rate. Only half of the residents (55%) reported feeling adequately prepared for their first year in residency; less than half cited adequate preparation to place stainless steel crowns (SSCs) (42%) and perform pulpotomies (45%). Far fewer felt adequately prepared to provide treatment for children six months to three years of age, including examinations (29%), infant oral exams (27%), and children with severe caries (37%). The program directors were even less positive about the adequacy of residents' preparation. Only 17% deemed them adequately prepared to place SSCs and 13% to perform pulpotomies. Approximately half reported their first-year residents were inadequately prepared to treat very young children and children with severe caries (55% each). This study found that the perceived inadequacy of predoctoral education in pediatric dentistry was consistent at both the learner and educator levels, supporting previous studies identifying inadequacies in this area.

    Intra-oral scanning technology is a very fast-growing field in dentistry since it responds to the need of an accurate three-dimensional mapping of the mouth, as required in a large number of procedures such as restorative dentistry and orthodontics. Nowadays, more than 10 intra-oral scanning devices for restorative dentistry have been developed all over the world even if only some of those devices are currently available on the market. All the existing intraoral scanners try to face with problems and disadvantages of traditional impression fabrication process and are based on different non-contact optical technologies and principles. The aim of this publication is to provide an extensive review of existing intraoral scanners for restorative dentistry evaluating their working principles, features and performances.

    The aim of this study was to determine the difference between the intended education by advanced education in prosthodontics (AEP) program directors and the perceived education received by AEP residents with respect to concepts of esthetic dentistry. Residents' confidence levels and current practices were also determined based on program level, with first- and second-year residents combined into "junior residents" and third- and fourth-year residents combined into "senior residents." Surveys were distributed to all U.S. and Canadian AEP program directors (N=52) in 2014 and residents (N=393) in 2015. The seven questions asked of directors and 20 asked of residents assessed resident training. The response rate for directors was 59.6% and for residents was 27.3%. Statistically significant results were found between the responding program directors' perceived education on esthetic principles and the responding residents' perceived education. The senior-level residents were more confident in each of the categories than residents at the junior level, although the difference was only significant for selecting porcelain systems to match inherent translucency, transfer of information to the laboratory, and surface staining or characterization. There was a difference between the program directors' intended teaching and the residents' perceptions with regards to bleaching, shade matching, selection of porcelain systems, transfer of information to the laboratory, and surface staining or characterization. The residents' confidence levels were higher at the senior level than those at the junior level in selecting porcelain systems, transfer of information to the laboratory, and staining/characterization. Faculty members in advanced prosthodontics programs may be able to use these findings to improve their residents' education in these areas.

  2. Advanced restorative dentistry - a problem for the elderly? An ethical dilemma.

    PubMed

    Murray, C G

    2015-03-01

    The type of dental restorations taken into old age may have an adverse effect on the quality of life of the elderly. Root caries and dry mouth increase in prevalence with age and may precipitate the breakdown of remaining natural and restored teeth. At present the availability of dental personnel and facilities in residential aged care facilities (RACFs) is limited, often non-existent, and the elderly living at home may be unable to easily gain access to dental care. Thus, the provision of appropriate and timely dental treatment may not occur, resulting in prolonged pain and suffering. It is important that, as our elderly population increasingly retain natural teeth into advanced old age, appropriate funds are made available to ensure their dental health is maintained. A lack of early intervention to arrest dental disease may result in life-threatening medical consequences in the elderly, such as ventilator assisted pneumonia or the need for a general anaesthetic and possible associated medical risks. Significant local disease, such as osteonecrosis, may also result from a lack of appropriate dental intervention. The necessity to remove questionable teeth prior to irradiation for neoplastic disease or bisphosphonate prescription for neoplastic disease or severe osteoporosis emphasizes the need for regular dental care. In contrast, extensive dental restorative treatment for younger people may have benefits, such as optimal dental aesthetics and oral function, but in older individuals careful consideration should be given to select the most appropriate treatment modality so that adverse situations can be avoided or their resolution simplified should they occur later when the individual is compromised or in a RACF. This may mean the use of conservative dental restorative materials and an avoidance of complex restorative options which may be difficult for the individual or RACF staff to maintain. Some years after receipt of their complex restorations they may be unable

    Potter's reno-facial syndrome is a rare innate abnormality. We bring 4 observations repertoried at the maternity of military hospital of Tunis over a period of 6 years (1997 - 2002). The purpose of our work is to determine after a review of the literature the echographic and foetopathologic characteristics, and the forecast of this syndrome. The frequency of the bilateral renale agenesis is of 0.27 per thousand. Positive diagnosis bases essentially on the ultrasound of the 2th, or the 3-th trimester. The signs of appeal are essentially the oligoamnios associated to an hypotrophy. The caryotype is systematic to eliminate an associeted chromosomic abnormality. Foetopathologic exam is usefull for the diagnosis. Main abnormality except the urinary pathology is the lung hypoplasia. Therapeutic interruption of the pregnancy in this situation not compatible with the extra-uterine life., only type IV authorize the development of the pregnancy according to echographic data and of foetal urinaire biochemistry. We insist on the early practice of the morphological ultrasound between 20 - 22 weeks for the diagnosis of foetal abnormalities and the place of the genetic advice in association with the geneticist in the coverage of the couple.

    Braschler, Thomas M.; Renaud, Philippe

    2013-01-01

    A paradigm shift is taking place in medicine and dentistry from using synthetic implants and tissue grafts to a tissue engineering approach that uses degradable porous three-dimensional (3D) material hydrogels integrated with cells and bioactive factors to regenerate tissues such as dental bone and other oral tissues. Hydrogels have been established as a biomaterial of choice for many years, as they offer diverse properties that make them ideal in regenerative medicine, including dental applications. Being highly biocompatible and similar to native extracellular matrix, hydrogels have emerged as ideal candidates in the design of 3D scaffolds for tissue regeneration and drug delivery applications. However, precise control over hydrogel properties, such as porosity, pore size, and pore interconnectivity, remains a challenge. Traditional techniques for creating conventional crosslinked polymers have demonstrated limited success in the formation of hydrogels with large pore size, thus limiting cellular infiltration, tissue ingrowth, vascularization, and matrix mineralization (in the case of bone) of tissue-engineered constructs. Emerging technologies have demonstrated the ability to control microarchitectural features in hydrogels such as the creation of large pore size, porosity, and pore interconnectivity, thus allowing the creation of engineered hydrogel scaffolds with a structure and function closely mimicking native tissues. In this review, we explore the various technologies available for the preparation of macroporous scaffolds and their potential applications. PMID:24455437

    2011-07-01

    Sports dentistry is one of the most recent and upcoming field in dentistry. It mainly includes the prevention and management of athletics-related orofacial injuries and associated oral diseases. The sports or team dentist assists athletes in the prevention, treatment, and diagnosis of oral injuries. The most significant aspect in preventing sports-related orofacial injuries is wearing basic protective devices such as properly-fitting helmets, face masks and/or mouth guards. Dental injuries are the most common type of orofacial injury sustained during participation in sports. Many athletes are not aware of the health implications of a traumatic injury to the mouth or of the potential for incurring severe head and orofacial injuries while playing. The dentist can play an imperative role in informing athletes, coaches and patients about the importance of preventing orofacial injuries in sports. The aim of this paper is to increase professional awareness and interest for orientation toward sports dentistry.

    Treatment of gingival recession is essential to rectify the esthetic and functional deficiencies of the patient and to combat further periodontal destruction. However, treating multiple recession cases is quite challenging, and therefore requires constant modifications of the prevalent treatment strategies as per the severity of the condition. The objective of this case report was to evaluate the effectiveness of coronally advanced flap (CAF) technique without vertical incisions using CAF brackets (CAF+B) for treating a patient presenting with class II gingival recession defects in relation to maxillary anteriors. Complete root coverage was observed, and the results were consistent even after 6 months. The current case report demonstrates good outcomes of the CAF + B technique without the use of any additional soft tissue grafts or vertical incisions, therefore, endorsing the promising potential of the CAF + B technique in multiple gingival recession cases.

    Since 1988, thirteen dental schools have provided dental undergraduate programmes within the United Kingdom (UK). In 2006, two new dental schools were created supporting dental education in the community. A further new dental school in Scotland will be accepting students in autumn 2008. In the past 25 years, extensive reorganisation of the NHS has resulted in long-term implications for the training of medical and dental academic staff. The number of academic clinicians is below the minimum viable level and external constraints, combined with a lack of suitable applicants, have led to a moratorium on academic recruitment within some Dental Schools. A detailed review of the historical and associated factors which have led to the problems presently besetting academic dentistry are discussed along with the initiatives introduced in the last 10 years to revitalise the speciality. Also, the present and future outlook for academic dentistry in other countries are discussed. Opinion is divided as to the appropriate setting for the training of undergraduate students between those who support community-based dental education and those who believe dental education should remain within research led dental establishments. External factors are moulding an unsatisfactory situation that is proving increasingly unattractive to the potential dental academic and the case for reform is obvious.

    Lam, R

    2014-12-01

    One disadvantage of the rapid advances in modern dentistry is that treatment options have never been more varied or confusing. Compounded by a more educated population greatly assisted by online information in an increasingly litigious society, a major concern in recent times is increased litigation against health practitioners. The manner in which courts handle disputes is ambiguous and what is considered fair or just may not be reflected in the judicial process. Although legal decisions in Australia follow a doctrine of precedent, the law is not static and is often reflected by community sentiment. In medical litigation, this has seen the rejection of the Bolam principle with a preference towards greater patient rights. Recent court decisions may change the practice of dentistry and it is important that the clinician is not caught unaware. The aim of this article is to discuss legal issues that are pertinent to the practice of modern dentistry through an analysis of legal cases that have shaped health law. Through these discussions, the importance of continuing professional development, professional association and informed consent will be realized as a means to limit the legal complications of dental practice.

    Advances in technology are changing the ways that patients experience dental treatment. Technology helps to decrease treatment time and makes the treatment more comfortable for the patient. One technological advance is the use of lasers in dentistry. Lasers are providing more efficient, more comfortable, and more predictable outcomes for patients. Lasers are used in all aspects of dentistry, including operative, periodontal, endodontic, orthodontic, and oral and maxillofacial surgery. Lasers are used for soft and hard tissue procedures in the treatment of pathologic conditions and for esthetic procedures. This article discusses how lasers work and their application in the various specialties within dentistry.

    3D printing has been hailed as a disruptive technology which will change manufacturing. Used in aerospace, defence, art and design, 3D printing is becoming a subject of great interest in surgery. The technology has a particular resonance with dentistry, and with advances in 3D imaging and modelling technologies such as cone beam computed tomography and intraoral scanning, and with the relatively long history of the use of CAD CAM technologies in dentistry, it will become of increasing importance. Uses of 3D printing include the production of drill guides for dental implants, the production of physical models for prosthodontics, orthodontics and surgery, the manufacture of dental, craniomaxillofacial and orthopaedic implants, and the fabrication of copings and frameworks for implant and dental restorations. This paper reviews the types of 3D printing technologies available and their various applications in dentistry and in maxillofacial surgery.

    During the last decade, there has been a major increase in the interest of nanostructured materials in advanced technologies for biomedical and dental clinical applications. Nanostructured materials are associated with a variety of applications within the dental and biomedical field, for example nanoparticles in drug delivery systems and nanostructured scaffolds in tissue engineering. More importantly, nanotechnology has also been linked with the modification of surface properties of synthetic implants in an attempt to improve their bioactivity, reliability and protection from the release of harmful or unnecessary metal ions. This is achieved through the use of nanocoatings and nanocomposite coatings. These new-generation coatings based on inorganic materials and biological materials such as proteins and peptides are currently investigated and applied. This chapter aims to give an overview of the recent advances in nanocoatings and their composites being investigated or used in dentistry.

    The technology in dentistry has been developed significantly lately, increasing the technological level of new materials, methods and equipment have been developed. Undoubtedly the CO2 laser has contributed to this evolution particular to the treatment of the infected dentin. CO2 laser can sterilize and promote increase 6 to 8 times of dentin resistance, through the transformation the hydroxyapatite in calcium-phosphato-hydroxyapatite. We can reassure our patients about the use of pulsed CO2 laser due to better preservation of dental structure and its benefits permitting advanced esthetic treatments. The CEREC system, registers a tri-dimensional image of the preparation through a scan system, and sends it to the computer and the operator will edit the restorations so the equipment will finish porcelain restoration. The authors used a new laser 650 nm for caries detection and the other low lever laser (670 nm and 730 nm) considered an auxiliary method to prevent and treat the hypersensitivity in dentin.

    'Ergonomic movement in dentistry' is a recently developed ergonomic programme for dental healthcare professionals which is intended to prevent work-related complaints and assist in recovering from them. The programme is recommended by disability insurers in cases of specific physical complaints, limitations or disability, as a consequence of which a dental healthcare professional is unable to carry out his or her work. In a four-day training programme, in one's own workplace, skills are taught in the areas of work organization, work attitude and movement. These skills are directly applied in the treatment ofpatients and, if necessary, further improved. In this way, one advances step by step to an ergonomic way of working. Evaluations have shown that the programme is advantageous for the attitude toward work, the workplace and the work organization as well as the reduction of disability.

    2014-07-01

    The Reno Orthopaedic Center (ROC) Trauma Fellowship business curriculum is designed to provide the fellow with a graduate level business practicum and research experience. The time commitments in a typical 12-month trauma fellowship are significant, rendering a traditional didactic master's in business administration difficult to complete during this short time. An organized, structured, practical business education can provide the trauma leaders of tomorrow with the knowledge and experience required to effectively navigate the convoluted and constantly changing healthcare system. The underlying principle throughout the curriculum is to provide the fellow with the practical knowledge to participate in cost-efficient improvements in healthcare delivery. Through the ROC Trauma Fellowship business curriculum, the fellow will learn that delivering healthcare in a manner that provides better outcomes for equal or lower costs is not only possible but a professional and ethical responsibility. However, instilling these values without providing actionable knowledge and programs would be insufficient and ineffective. For this reason, the core of the curriculum is based on individual teaching sessions with a wide array of hospital and private practice administrators. In addition, each section is equipped with a suggested reading list to maximize the learning experience. Upon completion of the curriculum, the fellow should be able to: (1) Participate in strategic planning at both the hospital and practice level based on analysis of financial and clinical data, (2) Understand the function of healthcare systems at both a macro and micro level, (3) Possess the knowledge and skills to be strong leaders and effective communicators in the business lexicon of healthcare, (4) Be a partner and innovator in the improvement of the delivery of orthopaedic services, (5) Combine scientific and strategic viewpoints to provide an evidence-based strategy for improving quality of care in a

    Ten miles south of Reno, on U.S. 395 near the junction of the road to historic Virginia City, is Steamboat Hot Springs, a popular stop for travelers since the mid-1800s. Legend has it that Mark Twain named the geothermal area because it looked and sounded like a chugging Mississippi River paddle-wheeler. It is said when he first saw the steam rising from the ground he exclaimed, {open_quotes}Behold! A Steamboat in the desert.{close_quotes} Over the years, the area has been used for its relaxing and curative qualities by Indians, settlers, and geothermal experts. Since the mid-1980s five geothermal power plants have been built at Steamboat Springs and in December 1996 it was announced that the proposed largest geothermal district heating system in the U.S. would supply an industrial park in the area. The active geothermal area is located within the north-south trending graben like trough between the Carson and Virginia Ranges at the southern end of Truckee Meadows. Hot springs and other geothermal features occur over an area of about one square mile. The mid-basin location is controlled by faulting more or less parallel to the major mountain-front faults. It is believed that the heat source for the system is a cooling magmatic body at depth. The Steamboat geothermal area consists of a deep, high-temperature (215{degrees}C to 240{degrees} C) geothermal system, a shallower, moderate-temperature (160{degrees}C to 18{degrees} C) system, and a number of shallow low-temperature (30{degrees}C to 80{degrees}C) subsystems. The higher temperature systems are used for electric-power generation. It is proposed that the exit fluids from the electric power plants be used for the geothermal district heating system.

  8. Biomaterials in Relation to Dentistry.

    PubMed

    Deb, Sanjukta; Chana, Simran

    2015-01-01

    Dental caries remains a challenge in the improvement of oral health. It is the most common and widespread biofilm-dependent oral disease, resulting in the destruction of tooth structure by the acidic attack from cariogenic bacteria. The tooth is a heavily mineralised tissue, and both enamel and dentine can undergo demineralisation due to trauma or dietary conditions. The adult population worldwide affected by dental caries is enormous and despite significant advances in caries prevention and tooth restoration, treatments continue to pose a substantial burden to healthcare. Biomaterials play a vital role in the restoration of the diseased or damaged tooth structure and, despite providing reasonable outcomes, there are some concerns with clinical performance. Amalgam, the silver grey biomaterial that has been widely used as a restorative material in dentistry, is currently in throes of being phased out, especially with the Minimata convention and treaty being signed by a number of countries (January 2013; http://mercuryconvention.org/Convention/) that aims to control the anthropogenic release of mercury in the environment, which naturally impacts the use of amalgam, where mercury is a component. Thus, the development of alternative restoratives and restoration methods that are inexpensive, can be used under different climatic conditions, withstand storage and allow easy handling, the main prerequisites of dental biomaterials, is important. The potential for using biologically engineered tissue and consequent research to replace damaged tissues has also seen a quantum leap in the last decade. Ongoing research in regenerative treatments in dentistry includes alveolar ridge augmentation, bone tissue engineering and periodontal ligament replacement, and a future aim is bioengineering of the whole tooth. Research towards developing bioengineered teeth is well underway and identification of adult stem cell sources to make this a viable treatment is advancing; however, this

    Graskemper, Joseph P

    2009-01-01

    Advertising in dentistry has steadily increased since the 1970s to become a leading choice of many dentists to promote their practices. The manner in which advertising progresses within the profession affects all dentists and how patients perceive dentistry as a profession. This paper presents ethical concepts that should be followed when dentists are pursuing practice promotion through advertising. It also raises questions that, hopefully, will increase attention and discussion on dental advertising. The paper concludes that ethical advertising is easily achieved by promoting patient education while not placing the dentist's self-interests ahead of the patient's. With this approach, dentistry may continue to be one of the most trusted professions.

    2004-10-01

    This article focuses on lasers and aesthetic dentistry and their unique parallel in history from their early development to their present day usage and application. The demand for aesthetic dentistry has had a major impact not only on treatment planning but also on the choice of materials, techniques, and equipment. It is this demand that has married the use of lasers with aesthetic dentistry. A short literature review on the five basic laser types precedes the basic premise of smile design and its critical importance in attaining the desirable aesthetic end result. A short review on biologic width and biologic zone reinforces their importance when manipulating gingival tissue. Four case reports highlight the use of diode, erbium, and carbon dioxide lasers. The end results show the power of proper treatment planning and the use of a smile design guide when using these instruments and confirm a conservative, aesthetic treatment without compromising the health and function of the patients.

    The prevention of tooth decay and the treatment of lesions and cavities are ongoing challenges in dentistry. In recent years, biomimetic approaches have been used to develop nanomaterials for inclusion in a variety of oral health-care products. Examples include liquids and pastes that contain nano-apatites for biofilm management at the tooth surface, and products that contain nanomaterials for the remineralization of early submicrometre-sized enamel lesions. However, the treatment of larger visible cavities with nanomaterials is still at the research stage. Here, we review progress in the development of nanomaterials for different applications in preventive dentistry and research, including clinical trials.

    Quantifying the height of the planetary boundary layer (PBL) is important to understand the transport behavior, mixing, and surface concentrations of air pollutants. In Reno, NV, located in complex, mountainous terrain with high desert climate, the daytime boundary layer can rise to an estimated 3km or more on a summer day due to surface heating and convection. The nocturnal boundary layer, conversely, tends to be much lower and highly stable due to radiative cooling from the surface at night and downslope flow of cool air from nearby mountains. With limited availability of radiosonde data, current estimates of the PBL height at any given time or location are potentially over or underestimated. To better quantify the height and characterize the PBL physics, we developed portable, lightweight sensors that measure CO2 concentrations, temperature, pressure, and humidity every 5 seconds. Four of these sensors are used on a tethered balloon system to monitor CO2 concentrations from the surface up to 300m. We will combine this data with Radio Acoustic Sounding System (RASS) data that measures vertical profiles of wind speed, temperature, and humidity from 40m to 400m. This experiment will characterize the diurnal evolution of CO2 concentrations at multiple heights in the PBL, provide insight into PBL physics during stability transition periods at sunrise and sunset, and estimate the nighttime PBL depth during August in Reno. Further, we expect to gain a better understanding of the impact of mixing volume changes (i.e., PBL height) on air quality and pollution concentrations in Reno. The custom portable sensor design will also be presented. It is expected that these instruments can be used for indoor or outdoor air quality studies, where lightness, small size, and battery operation can be of benefit.

    The importance of evidence for every branch of medicine in teaching in order to orient the practitioners among the great amount of most actual scientific information's, and to support clinical decisions, is well established in health care, including dentistry. The practice of evidence-based medicine is a process of lifelong, self-directed, problem-based learning which leads to the need for clinically important information about diagnosis, prognosis, therapy and other clinical and health care issues. Nowadays the practice of dentistry is becoming more complex and challenging because of the continually changing in dental materials and equipments, an increasingly litigious society, an increase in the emphasis of continuing professional development, the information explosion and the consumer movement associated with advances on the Internet. The need for reliable information and the electronic revolution have come together to allow the "paradigm shift" towards evidence-based health care. Recent years have seen an increase in the importance of evidence-based dentistry, aiming to reduce to the maximum the gap between clinical research and real world dental practice. Aim of evidence-based practice is the systematic literature review, which synthesizes the best evidences and provides the basis for clinical practice guidelines. These practice guidelines give a brief review of what evidence-based dentistry is and how to use it.

    1992-05-01

    Color vision is a critical component of restorative and esthetic dentistry, but dentists, as a group, do not have their color vision tested at any time during their careers. A study was undertaken to ascertain the color-vision status of practicing dental personnel at the University of Tennessee, College of Dentistry. One hundred fifty individuals, 75 men and 75 women, were screened. The results corroborated the existing medical data for the general population. It was found that 9.3% of the men and none of the women exhibited color-vision defect. Since most dentists are male, this study demonstrates an area of potential weakness for some practitioners. Once a color-vision problem is found, it is simple to remedy by employing a team approach to shade matching or mechanical means of matching shades (by the practitioner). No ethnic or racial distinctions were detected, although these have been reported in other studies.

    2012-07-01

    During the last 20 years, there has been considerable growth in the number of dental practices owned by corporate bodies. At present, well over 800 practices are owned by such bodies and they employ over 3000 dentists. This paper describes the factors that have led to this growth and explores the advantages and disadvantages of 'corporate' dentistry for patients, dentists, and the dental team. It then considers how and why dental practice may change over the next 20 years and concludes that by 2032 the small one-dentist practice may well be in the past. It is likely that smaller practices will have to work in some form of association if they are to survive. Although their current model is unstable, corporates are likely to adapt to a changing environment. By 2032, in some cases, dentistry may well be taken out of its conventional setting, into supermarkets or a school environment.

    The major objective in root canal treatment is to disinfect the entire root canal system. Cleaning, shaping, and use of antimicrobial medicaments are effective in reducing the bacterial load to some extent, but some bacteria do remain behind and multiply, causing reinfection. Taking into consideration the ineffectiveness, potential side-effects and safety concerns of synthetic drugs, the herbal alternatives for endodontic usage might prove to be advantageous. Over the past decade, interest in drugs derived from medicinal plants has markedly increased. Phytomedicine has been used in dentistry as anti-inflammatory, antibiotic, analgesic, sedative and also as endodontic irrigant. Herbal preparations can be derived from the root, leaves, seeds, stem, and flowers. The PubMed database search revealed that the reference list for natural medicaments featured 1480 articles and in dentistry 173 articles. A forward search was undertaken on the selected articles and author names. This review focuses on various natural drugs and products as well as their therapeutic applications when used as phytomedicine in dentistry. PMID:25558153

    The global movements of healthcare professionals and patient populations have increased the complexities of medical interactions at the point of service. This study examines interpreter mediated talk in cross-cultural general dentistry in Hong Kong where assisting para-professionals, in this case bilingual or multilingual Dental Surgery Assistants (DSAs), perform the dual capabilities of clinical assistant and interpreter. An initial language use survey was conducted with Polyclinic DSAs (n = 41) using a logbook approach to provide self-report data on language use in clinics. Frequencies of mean scores using a 10-point visual analogue scale (VAS) indicated that the majority of DSAs spoke mainly Cantonese in clinics and interpreted for postgraduates and professors. Conversation Analysis (CA) examined recipient design across a corpus (n = 23) of video-recorded review consultations between non-Cantonese speaking expatriate dentists and their Cantonese L1 patients. Three patterns of mediated interpreting indicated were: dentist designated expansions; dentist initiated interpretations; and assistant initiated interpretations to both the dentist and patient. The third, rather than being perceived as negative, was found to be framed either in response to patient difficulties or within the specific task routines of general dentistry. The findings illustrate trends in dentistry towards personalized care and patient empowerment as a reaction to product delivery approaches to patient management. Implications are indicated for both treatment adherence and the education of dental professionals.

    The major objective in root canal treatment is to disinfect the entire root canal system. Cleaning, shaping, and use of antimicrobial medicaments are effective in reducing the bacterial load to some extent, but some bacteria do remain behind and multiply, causing reinfection. Taking into consideration the ineffectiveness, potential side-effects and safety concerns of synthetic drugs, the herbal alternatives for endodontic usage might prove to be advantageous. Over the past decade, interest in drugs derived from medicinal plants has markedly increased.

    Gene therapy holds a promising future for bridging the gap between the disciplines of medicine and clinical dentistry. The dynamic treatment approaches of gene therapy have been advancing by leaps and bounds. They are transforming the conventional approaches into more precise and preventive ones that may limit the need of using drugs and surgery. The oral cavity is one of the most accessible areas for the clinical applications of gene therapy for various oral tissues. The idea of genetic engineering has become more exciting due to its advantages over other treatment modalities. For instance, the body is neither subjected to an invasive surgery nor deep wounds, nor is it susceptible to systemic effects of drugs. The aim of this article is to review the gene therapy applications in the field of dentistry. In addition, therapeutic benefits in terms of treatment of diseases, minimal invasion and maximum outcomes have been discussed.

    Two factors have, at times, pushed dentistry and medicine together and pulled them apart. The factor acting to create a symbiosis is the common biomedical or scientific foundation for these fields. The factor causing independence deals with socio-cultural matters impacting on the professions and the public. These two factors will be examined at three points in time when the relationship between the two professions was significantly important for the welfare of the public: the 1920s and '30s, the 1960s and '70s, and our own time. Contemporary major discussion about the alignment of dental education, scientific advances, and societal needs point to a need for a new look at how dentistry and medicine relate to one another.

    2016-12-01

    Development of improved designs of implant systems in dentistry have necessitated the study of stress fields in the implant regions of the mandible/maxilla for better understanding of the biomechanics involved. Photoelasticity has been used for various studies related to dental implants in view of whole field visualization of maximum shear stress in the form of isochromatic contours. The potential of digital photoelasticity has not been fully exploited in the field of implant dentistry. In this paper, the fringe field in the vicinity of the connected implants (All-On-Four® concept) is analyzed using recent advances in digital photoelasticity. Initially, a novel 3-D photoelastic model making procedure, to closely mimic all the anatomical features of the human mandible is proposed. By choosing appropriate orientation of the model with respect to the light path, the essential region of interest were sought to be analysed while keeping the model under live loading conditions. Need for a sophisticated software module to carefully identify the model domain has been brought out. For data extraction, five-step method is used and isochromatics are evaluated by twelve fringe photoelasticity. In addition to the isochromatic fringe field, whole field isoclinic data is also obtained for the first time in implant dentistry, which could throw important information in improving the structural stability of the implant systems. Analysis is carried out for the implant in the molar as well as the incisor region. In addition, the interaction effects of loaded molar implant on the incisor area are also studied.

    A Staged Z-pinch load is tested on the University of Nevada, Reno, Zebra Facility, located at the Nevada Terawatt Facility. The annular liner was argon (1-cm radius × 0.5-cm thickness), the target was a deuterium fill (either gas, or plasma), and the axial-magnetic field was either, Bz = 0, 100 G. This paper presents experimental data and analyses, including neutron-total yield and time-of-flight measurements. The results are benchmarked against the predictions from a 2D-MHD simulations. Results from this first (Spring 2016) series of experiments indicate that the initial-operating points selected for the mass injectors were sub-optimal. Design revisions are underway and changes in the injector timing will be implemented the Fall 2016 campaign. Companion papers in this session, and in poster papers, provide the basis for the SZP, designs and performance for the injectors, and details on the Zebra Facility.

    1997-05-01

    One of the major causes of anxiety in the dental clinic is the dental handpiece. Because dentists wish to provide a method which can replace the drill there has often been a premature use of the laser in dentistry. Various lasers have been introduced into the clinic before research has shown the laser used is of clinical benefit. Any new treatment method must not compromise the health of the patient being treated. Thus a method of evaluating the clinical abilities of dentists and their understanding the limitations of the laser used must be developed. Dentist must be trained in the basic interaction of the laser on oral tissues. The training has to concentrate on the variation of the laser wavelength absorption in the different tissues of the oral cavity. Because of the differences in the optical properties of these tissues great care must be exercised by practitioners using lasers on patients.

    Summary The 21st century dental practice is quite dynamic. New treatment protocols and new materials are being developed at a rapid pace. Ozone dental therapy falls into the category of new treatment protocols in dentistry, yet ozone is not new at all. Ozone therapy is already a major treatment modality in Europe, South America and a number of other countries. What is provided here will not be an exhaustive scientific treatise so much as a brief general introduction into what dentists are now doing with ozone therapies and the numerous oral/systemic links that make this subject so important for physicians so that, ultimately, they may serve their patients more effectively and productively.

    The purpose of this paper is to review the phenomenon of nanotechnology as it might apply to dentistry as a new field called nanodentistry. Treatment possibilities might include the application of nanotechnology to local anesthesia, dentition renaturalization, the permanent cure for hypersensitivity, complete orthodontic realignment in a single visit, covalently bonded diamondized enamel, and continuous oral health maintenance using mechanical dentifrobots. Dental nanorobots could be constructed to destroy caries-causing bacteria or to repair tooth blemishes where decay has set in, by using a computer to direct these tiny workers in their tasks. Dental nanorobots might be programed to use specific motility mechanisms to crawl or swim through human tissue with navigational precision, to acquire energy, to sense and manipulate their surroundings, to achieve safe cytopenetration, and to use any of a multitude of techniques to monitor, interrupt, or alter nerve-impulse traffic in individual nerve cells in real time.

    In recent years, a new class of drugs has revolutionized the treatment of autoimmune, allergic, infectious and many more diseases. These drugs are classified into three groups, cytokines, monoclonal antibodies and fusion proteins. Biological drugs have less side effects compared to conventional drugs, and may target special damaged cells, but not all the cells. There may be side effects such as infection, hypersensitivity, hematological disorders, cancer, hepatotoxicity and neurological disorders, but there is not enough evidence or long term studies of the mechanism of action and side effects of these drugs. Patients on biological therapy may need some special consideration in dentistry. This paper is a review regarding the classification, mechanism of action and side effects of these drugs, and dental consideration for patients on biological therapy. PMID:26372436

    Piezosurgery, or the use of piezoelectric devices, is being applied increasingly in oral and maxillofacial surgery. The main advantages of this technique are precise and selective cuttings, the avoidance of thermal damage, and the preservation of soft-tissue structures. Through the application of piezoelectric surgery, implant-site preparation, bone grafting, sinus-floor elevation, edentulous ridge splitting or the lateralization of the inferior alveolar nerve are very technically feasible. This clinical overview gives a short summary of the current literature and outlines the advantages and disadvantages of piezoelectric bone surgery in implant dentistry. Overall, piezoelectric surgery is superior to other methods that utilize mechanical instruments. Handling of delicate or compromised hard- and soft-tissue conditions can be performed with less risk for the patient. With respect to current and future innovative surgical concepts, piezoelectric surgery offers a wide range of new possibilities to perform customized and minimally invasive osteotomies.

    At the time of settlement and in the years leading up to the establishment in 1884 of the Odontological Society of Victoria, dentistry was an unregulated activity practised simultaneously by those that had received the best apprenticeship training and those that had no training what-so-ever. Under the influence of dentists such as John Iliffe however, this situation was soon to change. In 1887 the first Dental Act was passed making it a legal requirement for anyone practicing dentistry to be registered. In 1890, the Melbourne Dental Hospital opened its doors to its first patients, and in 1897, the Australian College of Dentistry, later to become a school within the University of Melbourne, began teaching a dental course. Combined, these three moments in history lead to the eradication of the unscrupulous practitioner and laid the path for the development and professionalization of dentistry in the state of Victoria.

    Herbs have been used for centuries to prevent and control disease. Herbal extracts are effective because they interact with specific chemical receptors within the body and are in a pharmacodynamic sense, drugs themselves. By using herbal medicines, patients have averted the many side effects that generally come with traditional medicines, but this does not mean that side effects do not occur. Only knowledgeable practitioners can prescribe the right herb and its proper dosage. Herbal medicines had been considered in every culture, however, pharmaceutical companies overturned this type of thinking. Now, pharmaceuticals are called traditional and herbs are libeled as the 'alternative'. The biggest challenge and problem is lack of information about the effect of herbs in oral tissues, mechanism of effect, and side effects. Several popular conventional drugs on the market are derived from herbs. These include aspirin (from white willow bark), digitalis (from foxglove), and sudafed (modelled after a component in the plant ephedra). Herbal products can vary in their potency. Therefore, care must be taken in selecting herbs, even so, herbal medicines have dramatically fewer side effects and are safer to use than conventional medications. The herbs described in this article are Bloodroot, Caraway, Chamomile, Echinacea, Myrrh, Peppermint, Rosemary, Sage, Thyme, Aloe Vera, Propolis, and a summary of other herbs that are useful in dentistry. Herbs may be good alternatives to current treatments for oral health problems but it is clear that we need more research.

    The success of dental implants has opened up countless treatment possibilities for restorative dentists to offer to their patients. Just as our clinical paradigms have had to change because of this new technology, so too must our paradigms concerning the way we communicate with our patients change if we are to get them to say "yes" to treatment that we know that they need. Success in clinical treatment using implants requires a systematic approach. A systematic approach to communicating with your patients will allow you to have the same high degree of success with treatment acceptance that is possible with dental implants. The key to the systems we have discussed is Relationship Centered Care. A relationship is fostered and enhanced through a Comprehensive Examination Process, a structured Consultation Process utilizing the influencing process and Financial Arrangements that allow the patient to receive what they want while the office maintains the profitability that it needs. A system for calculating rational fees can be utilized that allows the practice to have control over an area that traditionally was controlled by anecdotal factors. The Pride Institute has developed this material and is presenting it to the profession so that restorative dentists can truly practice implant dentistry profitably.

  15. Ultrasonics in Dentistry

    NASA Astrophysics Data System (ADS)

    Walmsley, A. D.

    Ultrasonic instruments have been used in dentistry since the 1950's. Initially they were used to cut teeth but very quickly they became established as an ultrasonic scaler which was used to remove deposits from the hard tissues of the tooth. This enabled the soft tissues around the tooth to return to health. The ultrasonic vibrations are generated in a thin metal probe and it is the working tip that is the active component of the instrument. Scanning laser vibrometry has shown that there is much variability in their movement which is related to the shape and cross sectional shape of the probe. The working instrument will also generate cavitation and microstreaming in the associated cooling water. This can be mapped out along the length of the instrument indicating which are the active areas. Ultrasonics has also found use for cleaning often inaccessible or different surfaces including root canal treatment and dental titanium implants. The use of ultrasonics to cut bone during different surgical techniques shows considerable promise. More research is indicated to determine how to maximize the efficiency of such instruments so that they are more clinically effective.

    ABSTRACT Ergonomics is much broader than preventing work‑related musculoskeletal disorders. The successful application of ergo‑ nomics assures high productivity, avoidance of illnesses and injuries, and increased satisfaction among workers. Unsuc‑ cessful application, on the other hand, can lead to work‑related musculoskeletal disorders (MSDs). This article sets forth broad important background information on ergonomics so that the dental practitioner can have a general awareness of ergonomic risk factors as well as some basis for understanding the ongo‑ ing dialogue about ergonomics, its diagnosis, treatment, and regulation. This article provides alternatives to be considered by the practitioner in light of the practitioner's own circumstances, experiences and goals. A practitioner wishing to improve his or her work environment, for whatever reason, may wish to follow an incremental approach to such efforts, as is briefy discussed here.

    Professional risk factors in dentistry may harm the dentist and the dental team. It is essential for the dentist to recognize these risk factors and protect against them. Among the various organs that are vulnerable in the dental situation are (in a nut-shell): The eyes, the ears, the respiratory system, the palm of the hand, and the back and the vertebrae. In addition, the dentist and the dental team must recognizes the potential for Hepatitis (A, B, C, D, E), and for the acquired immune deficiency syndrome due to the HIV virus. The primary means for protecting against these potential hazardous factors is meticulously keeping proper working conditions such as good ventilation of the operating room, using face masks which are capable of blocking even small particles, using eye protection and gloves, and proper seating at the chair. It is reasonable to adopt a routine of taking a vaccine against Influenza and Hepatitis B, and to routinely check the level of antibodies for Hepatitis B. Personal accidents- and severe-diseases-insurances, as well as insurance against losing the ability to work are advised for every dentist.

    Xanthogranulomatous pyelonephritis (XGP) is a rare histological subset of pyelonephritis characterized by being a chronic destructive granulomatous inflammation of the renal parenchyma. XGP is classified according to the extent of disease into two entities: within the renal cortex (focal or segmental XGP) or diffuse spread with pelvic communication (diffuse XGP). Although rare, XGP can have fatal complications including perinephric, psoas abscess, nephro-cutaneous fistula and reno-colic fistula. Only few studies have reported XGP complicated with psaos abcess and reno-colic fistula. Our aim is to add to the literature and share our experience with a case of extensive XGP eroding into the psoas muscle and ascending colon leading to severe sepsis that was successfully managed. We report a 56-year-old woman who was found to have XGP complicated by psoas abscess and reno-colic fistula managed by antibiotics, nephrostomy, and subsequent nephrectomy and partial colectomy.

  19. What is minimally invasive dentistry?

    PubMed

    Ericson, Dan

    2004-01-01

    Minimally Invasive Dentistry is the application of "a systematic respect for the original tissue." This implies that the dental profession recognizes that an artifact is of less biological value than the original healthy tissue. Minimally invasive dentistry is a concept that can embrace all aspects of the profession. The common delineator is tissue preservation, preferably by preventing disease from occurring and intercepting its progress, but also removing and replacing with as little tissue loss as possible. It does not suggest that we make small fillings to restore incipient lesions or surgically remove impacted third molars without symptoms as routine procedures. The introduction of predictable adhesive technologies has led to a giant leap in interest in minimally invasive dentistry. The concept bridges the traditional gap between prevention and surgical procedures, which is just what dentistry needs today. The evidence-base for survival of restorations clearly indicates that restoring teeth is a temporary palliative measure that is doomed to fail if the disease that caused the condition is not addressed properly. Today, the means, motives and opportunities for minimally invasive dentistry are at hand, but incentives are definitely lacking. Patients and third parties seem to be convinced that the only things that count are replacements. Namely, they are prepared to pay for a filling but not for a procedure that can help avoid having one.

    Patient safety has always been important and is a source of public concern. Recent high profile scandals and subsequent reports, such as the Francis report into the failings at Mid Staffordshire, have raised those concerns even higher. Mortality and significant morbidity associated with the practice of medicine has led to many strategies to help improve patient safety, however, with its lack of associated mortality and lower associated morbidity, dentistry has been slower at systematically considering how patient safety can be improved. Recently, several organisations, researchers and clinicians have discussed the need for a patient safety culture in dentistry. Strategies are available to help improve patient safety in healthcare and deserve further consideration in dentistry.

Various types of lasers with different wavelengths have been developed for use in a handy, easy and ergonomic manner. In daily paediatric dentistry, laser could be a very useful medical device which can completely replace the traditional high hand-piece and bur to realize a "micro-invasive" dentistry and a "clean" surgery, without bleeding and sutures. According to the international literature and in the light of recent researches, this work could give an overview on assisted laser therapy in paediatric dentistry, highlighting advantages and disadvantages of this new technology and pointing out the high compliance of the young patient.

    In the last decade, tissue engineering is a field that has been suffering an enormous expansion in the regenerative medicine and dentistry. The use of cells as mesenchymal dental stem cells of easy access for dentist and oral surgeon, immunosuppressive properties, high proliferation and capacity to differentiate into odontoblasts, cementoblasts, osteoblasts and other cells implicated in the teeth, suppose a good perspective of future in the clinical dentistry. However, is necessary advance in the known of growth factors and signalling molecules implicated in tooth development and regeneration of different structures of teeth. Furthermore, these cells need a fabulous scaffold that facility their integration, differentiation, matrix synthesis and promote multiple specific interactions between cells. In this review, we give a brief description of tooth development and anatomy, definition and classification of stem cells, with special attention of mesenchymal stem cells, commonly used in the cellular therapy for their trasdifferentiation ability, non ethical problems and acceptable results in preliminary clinical trials. In terms of tissue engineering, we provide an overview of different types of mesenchymal stem cells that have been isolated from teeth, including dental pulp stem cells (DPSCs), stem cells from human exfoliated deciduous teeth (SHEDs), periodontal ligament stem cells (PDLSCs), dental follicle progenitor stem cells (DFPCs), and stem cells from apical papilla (SCAPs), growth factors implicated in regeneration teeth and types of scaffolds for dental tissue regeneration.

    Introduction: Almost the entire human creativity today, from the standpoint of its efficiency and expediency, is conditioned with the existence of information systems. Most information systems are oriented to the management and decision-making, including health information system. System of health and health insurance together form one of the most important segments of society and its functioning as a compact unit. Increasing requirements for reducing health care costs while preserving or improving the quality of services provided represent a difficult task for the health system. Material and methods: Using descriptive metods by retreiiving literature we analyzed the latest solutions in information and telecommunications technology is the basis for building an effective and efficient health system. Computerization does not have the primary objective of saving, but the rationalization of spending in health care. It is estimated that at least 20-30% of money spent in health care can be rationally utilized. Computerization should give the necessary data and indicators for this rationalization. Very important are the goals of this project and the achievement of other uses and benefits, improving overall care for patients and policyholders, increasing the speed and accuracy of diagnosis in determining treatment using electronic diagnostic and therapeutic guidelines. Results and discussion: Computerization in dentistry began similarly as in other human activities–recording large amounts of data on digital media, and by replacing manual data processing to machine one. But specifics of the dental profession have led to the specifics of the application of information technology (IT), and continue to require special development of dental oriented and applied IT. Harmonization of dental software with global standards will enable doctors and dentists to with a few mouse clicks via the internet reach the general medical information about their patients from the central

  18. Nanotechnology applications in medicine and dentistry.

    PubMed

    Gupta, Jyoti

    2011-05-01

    Nanotechnology, or nanoscience, refers to the research and development of an applied science at the atomic, molecular, or macromolecular levels (i.e. molecular engineering, manufacturing). The prefix "nano" is defined as a unit of measurement in which the characteristic dimension is one billionth of a unit. Although the nanoscale is small in size, its potential is vast. As nanotechnology expands in other fields, clinicians, scientists, and manufacturers are working to discover the uses and advances in biomedical sciences. Applications of nanotechnology in medical and dental fields have only approached the horizon with opportunities and possibilities for the future that can only be limited by our imagination. This paper provides an early glimpse of nanotechnology applications in medicine and dentistry to illustrate their potentially far-reaching impacts on clinical practice. It also narrates the safety issues concerning nanotechnology applications.

  4. Combining traditional and adhesive dentistry to reconstruct the excessively worn dentition.

    PubMed

    Mizrahi, Basil

    2008-01-01

    Adhesive dentistry has changed the face of traditional dentistry and has the potential to improve esthetics and reduce tooth preparation. However, the materials and techniques used in adhesive dentistry are generally more technique sensitive than those used in traditional dentistry. It is, therefore, important that strict guidelines and protocols are followed to ensure long-term success. Clinicians must be able to determine where adhesive techniques and materials can be used and where traditional, biomechanically sound techniques and materials should be used. There appears to be an increasing trend of young to middle-aged patients presenting with advanced generalized tooth surface loss. These dentitions are conducive to treatment that combines traditional and adhesive materials and techniques. This article discusses guidelines for treatment of these dentitions and outlines the clinical treatment involved in the full-mouth rehabilitation of a worn dentition using a combination of all-ceramic crowns, porcelain and gold onlays, and porcelain veneers.

    Advances in biotechnology have brought gene therapy to the forefront of medical research. The concept of transferring genes to tissues for clinical applications has been discussed nearly half a century, but the ability to manipulate genetic material via recombinant DNA technology has brought this goal to reality. The feasibility of gene transfer was first demonstrated using tumour viruses. This led to development of viral and nonviral methods for the genetic modification of somatic cells. Applications of gene therapy to dental and oral problems illustrate the potential impact of this technology on dentistry. Preclinical trial results regarding the same have been very promising. In this review we will discuss methods, vectors involved, clinical implication in dentistry and scientific issues associated with gene therapy.

  8. Dental traumatology: an orphan in pediatric dentistry?

    PubMed

    Andreasen, Jens Ove; Lauridsen, Eva; Daugaard-Jensen, Jette

    2009-01-01

    Traumatic dental injuries are very frequent during childhood and adolescence. In fact, 2 out of 3 children have suffered a traumatic dental injury before adulthood. This fact links dental traumatology to pediatric dentistry. Unfortunately, this is not reflected by active participation by pediatric dentists in acute treatment, follow-up, and research. To examine the status of pediatric dentistry in relation to dental trauma, a publication analysis was undertaken in 1980, 1990, 2000, and 2007 about trauma articles published in 4 pediatric journals: journal of Dentistry for Children, Pediatric Dentistry, The journal of Pedodontics, and the International journal of Pediatric Dentistry. This study shows an average publication rate of trauma articles of approximately 3 percent of all articles published and with no improvement in later decennia. If only clinical studies are considered (leaving out case reports), the publication rate is less than 1 percent--completely out of proportion to the size of the problem dental trauma impose in children.

  9. Universal adhesives: the next evolution in adhesive dentistry?

    PubMed

    Alex, Gary

    2015-01-01

    Every so often a new material, technique, or technological breakthrough spurs a paradigm shift in the way dentistry is practiced. The development and evolution of reliable enamel and dentin bonding agents is one such example. Indeed, the so-called "cosmetic revolution" in dentistry blossomed in large part due to dramatic advances in adhesive technology. It is the ability to bond various materials in a reasonably predictable fashion to both enamel and dentin substrates that enables dentists to routinely place porcelain veneers, direct and indirect composites, and a plethora of other restorative and esthetic materials. In fact, the longevity and predictability of many (if not most) current restorative procedures is wholly predicated on the dentist's ability to bond various materials to tooth tissues. Adhesive systems have progressed from the largely ineffective systems of the 1970s and early 1980s to the relatively successful total- and self-etching systems of today. The latest players in the adhesive marketplace are the so-called "universal adhesives." In theory, these systems have the potential to significantly simplify and expedite adhesive protocols and may indeed represent the next evolution in adhesive dentistry. But what defines a universal system, and are all these new systems truly "universal" and everything they are claimed to be? This article will examine the origin, chemistry, strengths, weaknesses, and clinical relevance of this new genre of dental adhesives.

    The investigation on which this report is based was made in response to a request from the Bureau of Prisons, United States Department of Justice, for advice in regard to the development of a water supply for the proposed Southwestern Reformatory on the Fort Reno Military Reservation, 2 miles west of El Reno, Oklahoma. The tract set aside for the reformatory includes sec. 12 and the eastern half of sec. 11, T. 12 N, R. 8 W., and is about 1,000 acres in area. The proposed building site is in the north-central part of sec. 12, on a flat-topped hill just north of well No. 69. (See Plate 1.) It is understood that a maximum of 1,200 inmates is contemplated for this reformatory and that a water supply of about 120,000 gallons a day, or 85 gallons a minute, will be required in the summer. However, the potential capacity of the wells should be somewhat greater than 85 gallons a minute to allow for decline in yield. The author, who was assigned to this work by the United States Geological Survey, arrived in Oklahoma City April 21, 1931, and spent one week in field work in the area. After a conference with Dr. C.N. Gould, State Geologist of Oklahoma, it was decided that the possible sources of ground water to be investigated were the 'Red Beds' underlying the whole area, the Tertiary sands capping the hills north of the North Canadian River, and the river alluvium in the North Canadian River Valley. The area in which field work was done is shown on Plate 1 and includes approximately 105 square miles, lying chiefly north and west of El Reno, the county seat of Canadian County.

    1984-12-01

    Approximately a decade after the first plans for the teaching of community dentistry were made in the Nordic countries, a questionnaire survey of Nordic dental schools was conducted to find out to what extent community dentistry subjects had been introduced in undergraduate curricula. Replies were received from the 12 dental schools in Denmark, Finland, Norway and Sweden. These schools admitted 915 students in 1982-83. Seven had a department of community dentistry, and at least two others had plans to start one. About 100 h of teaching were given on community dentistry subjects during the 5-yr course of study, mostly on the traditional subjects of epidemiology, statistics, law and ethics. In some schools health education and other behavioral sciences subjects received a large amount of curriculum time. Decisionmaking theory and political science were not reported taught at any school. Three departments had attached clinics, with widely differing functions. The Nordic textbook in community dentistry was widely used, and separate examinations were held in community dentistry at most schools. Full-time postgraduate courses were offered at three schools. Although schools in all four countries expected the number of dental students to decrease in coming years, several schools expected community dentistry to expand with regard to curriculum time and staff, in keeping with trends in other countries.

    The object of making an impression in implant dentistry is to accurately relate an analogue of the implant or implant abutment to the other structures in the dental arch. This is affected by use of an impression coping which is attached to the implant or implant abutment. This impression coping is incorporated in an impression - much as a metal framework is 'picked up' in a remount impression for fixed prosthodontics. With implant copings the coping is usually attached to the implant or abutment with screws. The impression material used is usually an elastomeric impression material; the two types most widely used and shown to be the most appropriate are polyether and polyvinyl siloxane impression materials.

    2010-01-01

    SUMMARY The aim of this paper is to show and asses the clinical applications of the Mineral Trioxide Aggregate (MTA) in pediatric dentistry, either on primary teeth or on immature apex permanent teeth. We have described the primary tooth pulpotomy technique using MTA, that is characterized by a superior biocompatibility and a sealing ability that make it a more suitable compound compared to other materials in terms of result prediction on a long-term basis. We have also reported the direct capping technique using MTA on immature apex teeth; in these particular cases, MTA is undoubtedly preferable to conventional materials, especially in what its sealing characteristics concern. Furthermore, we have explained the apexogenesis clinical procedure, in which after a chamber pulpotomy on incomplete root development teeth, MTA is used in direct contact with the pulpar stump in order to save the root pulp vitality, allowing the apex and relative canal walls physiological maturation to take place. In case of necrotic teeth with immature apex, we describe the possibility of using MTA as an apical barrier making the apexification treatment faster and predictable, taking profit from its biocompatibility quality, its sealing ability and setting characteristic in humid environments. In all described applications, MTA has demonstrated to be a very versatile and extremely trustworthy material. Either literature and results obtained from the present experience, show how the use of MTA in Pediatric Dentistry, compared to commonly used materials, translates into pulp or periapical tissues being less swollen and, thus, guaranteeing a higher prediction of the therapeutic result on a short-term basis and on a long-term one.

    2013-01-01

    We characterize shallow subsurface faulting and basin structure along a transect through heavily urbanized Reno, Nevada, with high‐resolution seismic reflection imaging. The 6.8 km of P‐wave data image the subsurface to approximately 800 m depth and delineate two subbasins and basin uplift that are consistent with structure previously inferred from gravity modeling in this region of the northern Walker Lane. We interpret two primary faults that bound the uplift and deform Quaternary deposits. The dip of Quaternary and Tertiary strata in the western subbasin increases with greater depth to the east, suggesting recurrent fault motion across the westernmost of these faults. Deformation in the Quaternary section of the western subbasin is likely evidence of extensional growth folding at the edge of the Truckee River through Reno. This deformation is north of, and on trend with, previously mapped Quaternary fault strands of the Mt. Rose fault zone. In addition to corroborating the existence of previously inferred intrabasin structure, these data provide evidence for an active extensional Quaternary fault at a previously unknown location within the Truckee Meadows basin that furthers our understanding of both the seismotectonic framework and earthquake hazards in this urbanized region.

    The Reno Atmospheric Mercury Intercomparison Experiment (RAMIX) was carried out from 22 August to 16 September, 2011 in Reno, NV to evaluate the performance of new and existing methods to measure atmospheric mercury (Hg). Measurements were made using a common sampling manifold to which controlled concentrations of Hg species, including gaseous elemental mercury (GEM) and HgBr2 (a surrogate gaseous oxidized mercury (GOM) compound), and potential interferents were added. We present an analysis of Hg measurements made using the University of Washington's Detector for Oxidized Hg Species (DOHGS), focusing on tests of GEM and HgBr2 spike recovery, the potential for interference from ozone (O3) and water vapor (WV), and temporal variability of ambient reactive mercury (RM). The mean GEM and HgBr2 spike recoveries measured with the DOHGS were 95% and 66%, respectively. The DOHGS responded linearly to HgBr2. We found no evidence that elevated O3 interfered in the DOHGS RM measurements. A reduction in RM collection and retention efficiencies at very high ambient WV mixing ratios is possible. Comparisons between the DOHGS and participating Hg instruments demonstrate good agreement for GEM and large discrepancies for RM. The results suggest that existing GOM measurements are biased low.

    Concentrations of gaseous elemental mercury (GEM), gaseous oxidized mercury (GOM) and particulate-bound mercury (PBM) were measured along with ancillary variables 9 km east of downtown Reno, Nevada, U.S.A. from November 2006 through March 2009. Mean two-year (February 2007 through January 2009) GEM, GOM, and PBM concentrations were 2.0+/-0.7 ng m(-3) (+/-standard deviation), 18+/-22 pg m(-3), and 7+/-7 pg m(-3), respectively. Data collected were compared with observations made at another location just north of the city at 169 m higher elevation. At both locations higher concentrations of GEM and PBM occurred in periods with little atmospheric mixing, indicating that local sources were important for enhancing GEM and PBM concentrations in Reno above that considered continental background. Concentrations of GOM were higher (maximum of 177 pg m(-3)) during periods with higher temperature and lower dew point. Higher GOM concentrations at the higher elevation site with less urban impact relative to the valley site, along with other data trends, support the hypothesis that in northern Nevada subsiding dry air from the free troposphere is a source of GOM to the surface.

    Despite all the dental information acquired over centuries and the importance of proteome research, the cross-link between these two areas only emerged around mid-nineties. Proteomic tools can help dentistry in the identification of risk factors, early diagnosis, prevention, and systematic control that will promote the evolution of treatment in all dentistry specialties. This review mainly focuses on the evolution of dentistry in different specialties based on proteomic research and how these tools can improve knowledge in dentistry. The subjects covered are an overview of proteomics in dentistry, specific information on different fields in dentistry (dental structure, restorative dentistry, endodontics, periodontics, oral pathology, oral surgery, and orthodontics) and future directions. There are many new proteomic technologies that have never been used in dentistry studies and some dentistry areas that have never been explored by proteomic tools. It is expected that a greater integration of these areas will help to understand what is still unknown in oral health and disease.

    Dr Donna Rumberger graduated from New York University College of Dentistry in 1980 and has practiced dentistry in Manhattan ever since. Even before her graduation, she was active in organized dentistry, always viewing it as a conduit for helping other people. Working with the American Association of Women Dentists, she was cofounder of the Smiles for Success Foundation, a program started in New York City that helps women advance from welfare into the workforce with restored, healthy smiles. That program now has expanded to 14 other cities. Working with organized dentistry in New York City, she has been instrumental in initiating and running the Skate Safe program, which provides mouthguards and oral home care education for inner city children in Harlem. In addition, she has worked with the dentistry merit badge program for the Boy Scouts of America Jamborees, helped coalesce women's dental organizations in New York City, and led her dental society to collaborate with Columbia University in a program to improve access to dental care. As further evidence of her ability to get things done, she also has served as president of the American Association of Women Dentists, the Midtown Dental Society, and the New York County Dental Society--one of the largest dental societies in the country.

  3. Assessment of objectives of post-doctoral general dentistry programs in Canada.

    2000-01-01

    Objectives of hospital-based post-doctoral general dentistry programs in Canada were assessed by questionnaire. Seventy percent (14 of 20) of the program directors responded. Educational goals and objectives were assessed in professional skills and practice management, public health and preventive dentistry, oral medicine and pathology, special needs patient care, trauma and emergency care, restorative/prosthodontic care, endodontics, orthodontics/pediatric dentistry, oral surgery, periodontics, pharmacology, and functioning in a hospital. High rankings of proficiency were related to primary care, restorative/prosthodontic, endodontic, and surgical care. Emergency care, sedation, and pharmacology were also ranked highly. Lower rankings of proficiency were reported in orthodontics, aspects of public health dentistry, practice management, and advanced oral and maxiliofacial surgery. When the results of the Canadian survey were compared with those of a survey of US post-doctoral general dentistry programs, substantial similarity was seen. The findings support continuing reciprocity in accreditation standards between the Canadian and American Commissions on Dental Education and Dental Accreditation.

  4. The era of whiter teeth: advertising in American dentistry 1910-1950.

    PubMed

    Grumsen, Stine

    2009-01-01

    It has often been argued that the public image of dentists has been tainted by association with fear and pain into an image of evil 'psychodontists' and that there is an apparent lack of 'role models' in popular film, television, art and literature concerned with dentistry. This paper argues that we get a different picture when looking at different media. Advertisements introduce into a public domain, positive images of dentistry which crucially differ from the images found in other popular media. This paper traces the public image of dentistry in early 20th-century America, as seen through dentifrice advertisements, and suggests three important reasons for studying advertisements: First, advertisements provide a supplement to studies of popular images of dentistry carried out so far. Second, advertisements have played an important part in advancing oral hygiene as a public concern. And third, advertisements provide the historian of dentistry with a unique opportunity for analyzing the complex and interwoven relationship of popular and professional discourses, since ads have acted as catalysts for professional discussions and self-reflection among dentists.

    2012-05-01

    This cross-sectional questionnaire survey assessed the motives for choosing dentist as a profession among dentistry students at Damascus University, Syrian Arab Republic. A total of 408 undergraduate students (233 males and 175 females) aged 18-23 years were selected randomly from students in the second, third and fourth years of dentistry study. They completed a questionnaire that enquired about their reasons for studying dentistry as well as their sociodemographic characteristics. The number of admissions in females had increased over the 3 years. Most parents of the students were university-educated. The main motivation for choosing dentistry was as a means to achieve personal goals, including getting a good job abroad, having financial independence, and attaining a good reputation. There were significant differences between the sexes with regard to the reasons for choosing dentistry.

    AlSarheed, Maha A.

    2016-01-01

    Objectives: To identify the intranasal (IN) sedatives used to achieve conscious sedation during dental procedures amongst children. Methods: A literature review was conducted by identifying relevant studies through searches on Medline. Search included IN of midazolam, ketamine, sufentanil, dexmedetomidine, clonidine, haloperidol and loranzepam. Studies included were conducted amongst individuals below 18 years, published in English, and were not restricted by year. Exclusion criteria were articles that did not focus on pediatric dentistry. Results: Twenty studies were included. The most commonly used sedatives were midazolam, followed by ketamine and sufentanil. Onset of action for IN midazolam was 5-15 minutes (min), however, IN ketamine was faster (mean 5.74 min), while both IN sufentanil (mean 20 min) and IN dexmedetomidine (mean 25 min) were slow in comparison. Midazolam was effective for modifying behavior in mild to moderately anxious children, however, for more invasive or prolonged procedures, stronger sedatives, such as IN ketamine, IN sufentanil were recommended. In addition, ketamine fared better in overall success rate (89%) when compared with IN midazolam (69%). Intranasal dexmedetomidine was only used as pre-medication amongst children. While its’ onset of action is longer when compared with IN midazolam, it produced deeper sedation at the time of separation from the parent and at the time of anesthesia induction. Conclusion: Intranasal midazolam, ketamine and sufentanil are effective and safe for conscious sedation, while intranasal midazolam, dexmedetomidine and sufentanil have proven to be effective premedications.

    Wróblewska, Marta; Strużycka, Izabela; Mierzwińska-Nastalska, Elżbieta

    2015-01-01

    In the past decades significant scientific progress has taken place in the knowledge about biofilms. They constitute multilayer conglomerates of bacteria and fungi, surrounded by carbohydrates which they produce, as well as substances derived from saliva and gingival fluid. Modern techniques showed significant diversity of the biofilm environment and a system of microbial communication (quorum sensing), enhancing their survival. At present it is believed that the majority of infections, particularly chronic with exacerbations, are a result of biofilm formation, particularly in the presence of biomaterials. It should be emphasised that penetration of antibiotics and other antimicrobial agents into deeper layers of a biofilm is poor, causing therapeutic problems and necessitating sometimes removal of the implant or prosthesis. Biofilms play an increasing role in dentistry as a result of more and more broad use in dental practice of plastic and implantable materials. Biofilms are produced on the surfaces of teeth as dental plaque, in the para-nasal sinuses, on prostheses, dental implants, as well as in waterlines of a dental unit, constituting a particular risk for severely immunocompromised patients. New methods of therapy and prevention of infections linked to biofilms are under development.

    In this paper, the venezuelan dentists express their necessities of knowing certain aspects of psychology that could be useful in the relations with their patients. In the investigation a 16 item questionnaire was elaborated, taking 5 areas in consideration: a. Psychological management of the dental patient. b. Psychological consequences of the dental disease. c. Dental disease psychogenesis. d. Patient first contact behavior. e. Aspects of work organization. 100 dentists and 100 dental students of the last 2 years were inquired, in order to compare these two populations at the XXXth Congress of the venezuelan dentists. The two proportion coefficient test was used with: P less than or equal to 0.01. As a result 4 groups of items had a significant difference: a. Patient dissertation. b. Children with problematic behavior. c. Anxious patients; and d. Professional fees. Quantitatively 16 items were recognized as items in with Psychology could be useful to be applied in dentistry. The article concludes with 6 recommendations underlining the important role of the dental psychology in the dental school as well as in private practice.

    2014-01-01

    This study extends the current research on the relationship between neighborhood disorder and violent crime rates by incorporating spatial effects and the reciprocal relationship between disorder and violent crime. In particular, we test for both the potential effect of disorder on violence as well as how changes in violent crime rates can impact neighborhood levels of disorder. We control for a variety of factors related to social disorganization theory that can lead to crime and potentially disorder. In order to disentangle these relationships, we use a cross-lagged auto-regressive structural equation model and a unique dataset comprised of calls for police service and reported incidents for 117 neighborhoods in Reno, NV. We find that higher rates of disorder lead to significant, but modest, increases in violent crime, but only aggravated assaults lead to increases in disorder. These effects hold true above and beyond the effect of social disorganization and the influence of spatially proximate neighborhoods.

    1996-12-31

    In this paper, potential revenues from the proposed geothermal district heating/cooling system for the hotel/casino complexes in downtown Reno, Nevada are estimated by analyzing their actual electricity and natural gas bills during 1993 through 1994. The geothermal system appears to be feasible, and financially very attractive. The geothermal district system can meet the entire heating and cooling requirements of the hotel/casinos, generating total potential revenues of $3,486,000 per year. Also, other buildings around the downtown area such as Saint Mary`s Hospital, several motels, business complexes, Washoe County School District Building, and even the UNR campus will add extra potential revenues, if these buildings are connected to the geothermal grid. Since most buildings around the downtown use central heating and cooling system, the retrofit costs for the both system should be minimal.

    Objective: Measure the adoption and utilization of, opinions about, and attitudes toward clinical computing among general dentists in the United States. Design: Telephone survey of a random sample of 256 general dentists in active practice in the United States. Measurements: A 39-item telephone interview measuring practice characteristics and information technology infrastructure; clinical information storage; data entry and access; attitudes toward and opinions about clinical computing (features of practice management systems, barriers, advantages, disadvantages, and potential improvements); clinical Internet use; and attitudes toward the National Health Information Infrastructure. Results: The authors successfully screened 1,039 of 1,159 randomly sampled U.S. general dentists in active practice (89.6% response rate). Two hundred fifty-six (24.6%) respondents had computers at chairside and thus were eligible for this study. The authors successfully interviewed 102 respondents (39.8%). Clinical information associated with administration and billing, such as appointments and treatment plans, was stored predominantly on the computer; other information, such as the medical history and progress notes, primarily resided on paper. Nineteen respondents, or 1.8% of all general dentists, were completely paperless. Auxiliary personnel, such as dental assistants and hygienists, entered most data. Respondents adopted clinical computing to improve office efficiency and operations, support diagnosis and treatment, and enhance patient communication and perception. Barriers included insufficient operational reliability, program limitations, a steep learning curve, cost, and infection control issues. Conclusion: Clinical computing is being increasingly adopted in general dentistry. However, future research must address usefulness and ease of use, workflow support, infection control, integration, and implementation issues. PMID:16501177

    The book appraised in this edition of Chronicles of Medical History, History of Dentistry in Nigeria, is a product of many years of painstaking research. The Author, Professor Eyitope Ogunbodede, has put together an excellent book that is a great work of art. Dentistry is one of the first specialties in medicine with a very long history; evidence of periodontal disease has been traced back to at least 100, 000 years in human remains. However, the book by Professor Ogunbodede is the first comprehensive record of the History of dentistry in Nigeria. It is a must-read for every medical professional practicing in Nigeria and a worthy addition to every library. PMID:27721686

    2015-05-01

    In today's dental school curricula, an increasing amount of time is dedicated to technological advances, and preventive dentistry topics may not be adequately addressed. Freshman (D1) students participated in a new Introduction to Preventive Dentistry course, which consisted of didactic lectures, active learning breakout sessions and case-based studies. The goal of this study was to determine if D1 dental students completing the course had a better knowledge and comfort level with basic preventive dentistry concepts and caries risk assessment than the upcoming graduating senior dental students. Following the completion of the course, D1 students were administered a survey that assessed their comfort level describing preventive dentistry topics to patients. This was immediately followed by an unannounced examination over the same topics. Senior (D4) students, who had not taken a formal course, reported statistically significant higher comfort levels than D1 students. However, the D4s scored significantly lower in all of the examination areas than the D1 students. Higher scores in D1s may have been due to recent exposure to the course material. However, the basic nature of the content-specific questions should be easily answered by novice practitioners educating their patients on oral disease prevention. As the current data shows lower content-specific scores of basic preventive dentistry knowledge amongst graduating D4 students, this may indicate a need for more guidance and education of students during the patient care. This study showed that implementation of a formalised course for D1 students can successfully ameliorate deficiencies in knowledge of preventive dentistry topics.

    2011-01-01

    Dentistry in recent years has developed interest in the field of intellectual property rights (IPR) and Patents due to extensive research in the fraternity and existing competition. There have been various patent applications and grants in the field of dentistry abroad due to better understanding of IPR but India still has very few patent grants and applications on the subject matter. This review article in particular deals with the understanding of IPR and Patents as a whole, especially for dental professionals involved in research and development. Hence, this would also act as an asset for dental researchers to explore and expand their scope of activities, with special privileges empowered for their work.

It reviews the changing context of dentistry, not least the reforms being introduced by the health and social care bill. It suggests that this new context will reinforce the need to consider the business side of dental practice, in particular, the importance of quality, creativity and innovation, alongside the importance of meeting the needs of patients. An entrepreneurial approach will be required in order to sustain dental practice in an increasingly competitive environment.

  11. A brief history of aerospace dentistry.

    PubMed

    Savage, D Keith

    2002-07-01

    In April 2000, the National Academy of Sciences Institute of Medicine (NAS/IOM) Committee on Space Medicine held a workshop under contract with the National Aeronautics and Space Administration (NASA) to explore "innovative terrestrial medical care." There was also a NAS/IOM panel held on "Space Dentistry: Maintaining Astronauts' Oral Health on Long Missions." Air Force Dental Officer Col. Shannon E. Mills chaired the dental committee. Many questions were raised but few answers were available. Prevention was emphasized with the hope that within twenty to thirty years there may be a number of astronaut candidates with no existing dental restorations and with optimum oral health. However, there remains the concern that trauma to teeth could occur within the confines of a zero gravity space capsule as crew members carry out their daily responsibilities. The possibility is evident considering the duration of a space flight to Mars and back could require up to three years. The dental concerns of a space mission are only a small part of a much larger team effort, however, it is one not to be overlooked. An historical review of dentistry's involvement with America's flight and space programs of the 20th Century would be prudent. Many of same questions asked today were addressed in the early days of aviation dentistry as it transitioned into aerospace dentistry. Any past research and experiences would help serve as a foundation to build upon.

    An ultrasound (US) gives a visible image of the organs that are present inside the body. In medicine it serves for diagnosing and also its therapeutic benefits are well established for bone healing, osteointegration and soft tissue healing. In dentistry it is widely used for diagnostic purposes. When it was discovered it was introduced for therapeutic purposes, but due to lack of clinical studies its use as therapy was remittent in dentistry. The aim of the present paper was to establish the efficiency of therapeutic US in maxillofacial region for alleviating the pain and to see the other applications. Our search included the English terms like ultrasonography, applications, dentistry in Google search engine, PubMed and Medline from 1980 to 2015. We found very few articles showing the effects of therapeutic Ultrasound (US) in treatment of pain and healing in dentistry. We concluded that clinical benefits of in vivo studies were very little and demands further rigorous research to strive for the therapeutic success of US. PMID:27630969

  14. Pay for performance: will dentistry follow?

    PubMed Central

    2010-01-01

    Background "Pay for performance" is an incentive system that has been gaining acceptance in medicine and is currently being considered for implementation in dentistry. However, it remains unclear whether pay for performance can effect significant and lasting changes in provider behavior and quality of care. Provider acceptance will likely increase if pay for performance programs reward true quality. Therefore, we adopted a quality-oriented approach in reviewing those factors which could influence whether it will be embraced by the dental profession. Discussion The factors contributing to the adoption of value-based purchasing were categorized according to the Donabedian quality of care framework. We identified the dental insurance market, the dental profession position, the organization of dental practice, and the dental patient involvement as structural factors influencing the way dental care is practiced and paid for. After considering variations in dental care and the early stage of development for evidence-based dentistry, the scarcity of outcome indicators, lack of clinical markers, inconsistent use of diagnostic codes and scarcity of electronic dental records, we concluded that, for pay for performance programs to be successfully implemented in dentistry, the dental profession and health services researchers should: 1) expand the knowledge base; 2) increase considerably evidence-based clinical guidelines; and 3) create evidence-based performance measures tied to existing clinical practice guidelines. Summary In this paper, we explored factors that would influence the adoption of value-based purchasing programs in dentistry. Although none of these factors were essential deterrents for the implementation of pay for performance programs in medicine, the aggregate seems to indicate that significant changes are needed before this type of program could be considered a realistic option in dentistry.

  15. Fault Imaging with High-Resolution Seismic Reflection for Earthquake Hazard and Geothermal Resource Assessment in Reno, Nevada

    SciTech Connect

    2012-05-05

    The Truckee Meadows basin is situated adjacent to the Sierra Nevada microplate, on the western boundary of the Walker Lane. Being in the transition zone between a range-front normal fault on the west and northwest-striking right-lateral strike slip faults to the east, there is no absence of faulting in this basin. The Reno- Sparks metropolitan area is located in this basin, and with a signi cant population living here, it is important to know where these faults are. High-resolution seismic reflection surveys are used for the imaging of these faults along the Truckee River, across which only one fault was previously mapped, and in southern Reno near and along Manzanita Lane, where a swarm of short faults has been mapped. The reflection profiles constrain the geometries of these faults, and suggest additional faults not seen before. Used in conjunction with depth to bedrock calculations and gravity measurements, the seismic reflection surveys provide de nitive locations of faults, as well as their orientations. O sets on these faults indicate how active they are, and this in turn has implications for seismic hazard in the area. In addition to seismic hazard, the faults imaged here tell us something about the conduits for geothermal fluid resources in Reno.

    Oral health is - literally - vital to good general health, not least because the mouth is the sentinel of the body. Dentistry, the Cinderella of health care, faces immense challenges of globalisation. Governments, having spent freely on everything from defence to social security, face mountains of debts which make budget cutbacks essential. Simultaneously, most developed countries have to pay increasing costs of caring for rapidly ageing populations. Dentistry is being pulled two ways: wealthy members of society demand high-end expensive treatment, much of it cosmetic rather than necessary to deal with disease, whereas many millions of poor people in developing countries cannot afford basic dental treatment and may never see a dentist. Too many governments and dentists persist with the expensive and destructive regime of 'drill and fill (and bill)'. International advances in care may not reach the clinician's chair because treatment guidelines and payments are set locally. An international symposium to celebrate Mikako Hayashi becoming Professor of Restorative Dentistry and Endodontology at Osaka University concluded that dentistry should move from an increasingly un-affordable curative model to a cost-effective evidence-based preventive model. The goal is to help people retain healthy natural teeth throughout their lives, as an essential part of enhancing their general health.

    The scope was to analyze the perceptions of dentistry students at the State University of Montes Claros, Brazil, regarding dentistry, the job market and the public healthcare system. For this, a triangulation method was employed, using a self-administered questionnaire and interviews. The quantitative data were submitted to univariate and multivariate analysis, using Poisson regression, where p<0.05. Content analysis was used for the qualitative data. The majority reported expecting to obtain work in the public healthcare system, stated that the dentistry course prepares students for this market as the curriculum integrates both teaching and service, reported being in favor of greater experience in the public healthcare system and said they would not take classes in Public Health if they were optional. Contact with the social context through teaching/service integration in the advanced semesters of the dentistry course appears to contribute to the development of new professional skills for working in the public sector. However, the students' perceptions revealed contradictions, considering the low value they attributed to the classes on Public Health and their perception of the public system as a residual job option.

    Implant therapy is rapidly becoming a standard of care for replacing missing dentition. Predoctoral dental curricula include some training in the implant restorative phase but offer limited exposure to the surgical phase, so it is important for postdoctoral general dentistry residency programs to provide competency training in all phases of implant therapy. The aim of this study was to determine the training needed for general dentistry residents to achieve competence in this area, specifically by defining the number of clinical experiences necessary in both the surgical and prosthetic phases of implant-retained mandibular overdenture construction (IRMOD). Fifteen Advanced Education in General Dentistry (AEGD) residents at one academic dental institution placed two implants in a total of 50 patients with edentulous mandibles and subsequently restored them with IRMOD. The supervising faculty member and the residents evaluated the competency level on a five-point scale after each implant placement and prosthetic case completion. According to the faculty evaluations, the residents achieved surgical competence after placing two implants in four to six cases and prosthetic management competence after restoring two to four cases of IRMOD. All 50 patients were satisfied with the treatment outcomes of IRMOD. This study concluded that general dentistry residents could potentially achieve competence in both the surgical and prosthetic phases of implant therapy while enrolled in an AEGD program.

    The purpose of this study was twofold: 1) to examine website content provided by U.S. and Canadian pediatric dentistry residency programs, and 2) to understand aspects of program websites that dental students report to be related to their interests. Sixty-eight program websites were reviewed by five interprofessional evaluators. A thirty-six-item evaluation form was organized into 1) program descriptive items listed on the American Academy of Pediatric Dentistry (AAPD) website (n=21); 2) additional program descriptive items not listed on the AAPD website but of interest (n=9); and 3) items related to website interface design (n=5). We also surveyed fifty-four dental students regarding their interest in various aspects of program descriptions. The results of this study suggest that pediatric dentistry residency programs in general tend to provide identical or less information than what is listed on the AAPD website. The majority of respondents (76 percent) reported that residency program websites would be their first source of information about advanced programs. The greatest gap between the available website information and students' interests exists in these areas: stipend and tuition information, state licensure, and program strengths. Pediatric dentistry residency programs underutilize websites as a marketing and recruitment tool and should incorporate more information in areas of students' priority interests.

    In a survey of all PhD programs in psychology in the United States and Canada, the authors documented the quantitative methodology curriculum (statistics, measurement, and research design) to examine the extent to which innovations in quantitative methodology have diffused into the training of PhDs in psychology. In all, 201 psychology PhD programs (86%) participated. This survey replicated and extended a previous survey (L. S. Aiken, S. G. West, L. B. Sechrest, & R. R. Reno, 1990), permitting examination of curriculum development. Most training supported laboratory and not field research. The median of 1.6 years of training in statistics and measurement was mainly devoted to the modally 1-year introductory statistics course, leaving little room for advanced study. Curricular enhancements were noted in statistics and to a minor degree in measurement. Additional coverage of both fundamental and innovative quantitative methodology is needed. The research design curriculum has largely stagnated, a cause for great concern. Elite programs showed no overall advantage in quantitative training. Forces that support curricular innovation are characterized. Human capital challenges to quantitative training, including recruiting and supporting young quantitative faculty, are discussed. Steps must be taken to bring innovations in quantitative methodology into the curriculum of PhD programs in psychology.

    Medical emergencies can and do occur in the practice of dentistry. Although most emergencies take place in adults, serious problems can also develop in younger patients. The contemporary dentist must be prepared to manage expeditiously and effectively those few problems that do arise. Basic life support (as necessary) is all that is required to manage many emergency situations, with the addition of specific drug therapy in some others. Preparation of the office and staff includes basic life support (annually), pediatric advanced life support, development of an emergency team, consideration for emergency medical services, and the availability of emergency drugs and equipment with the ability to use these items effectively. As with the adult patient, effective management of pain (local anesthesia) and anxiety (behavioral management, conscious sedation) will minimize the development of medical emergencies.

    We have carefully examined, in both analytical and numerical ways, how small the terrestrial matter effects can be in a given medium-baseline reactor antineutrino oscillation experiment like JUNO or RENO-50. Taking the forthcoming JUNO experiment as an example, we show that the inclusion of terrestrial matter effects may reduce the sensitivity of the neutrino mass ordering measurement by and a neglect of such effects may shift the best-fit values of the flavor mixing angle θ12 and the neutrino mass-squared difference Δ21 by about 1σ to 2σ in the future data analysis. In addition, a preliminary estimate indicates that a 2σ sensitivity of establishing the terrestrial matter effects can be achieved for about 10 years of data taking at JUNO with the help of a suitable near detector implementation.

    2014-01-01

    Background: In Isfahan, the second metropolitan in Iran, there are 1448 dentistry treatment centers that most of them are inefficient. Today, efficiency is the most important issue in health care centers as well as dentistry clinics. The goal of this research is to investigate the affordability and efficiency of dentistry clinics in Isfahan province, Iran. Methods: The current work is a quantitative research, designed in three methodological steps, including two surveys and experimental studies, for understanding current deficiencies of Iranian dentistry clinics. First, we ran a survey. Then, we analyzed the results of the questionnaires which guided us to find a particular intervening package to improve the efficiency of the clinics. At the second step, we chose an inefficient clinic named Mohtasham (Iran, Isfahan) to evaluate our intervening package. Results: Based on what the interviewees answered, we mention the most important issues to be considered for improving the efficiency of dental clinics in Isfahan. By considering mentioned problematic issues, an intervening package was designed. This intervening package was applied in Mohtasham clinic, since June 2010. It improved the clinic's income from 16328 US$ with 4125 clients in 2010, to 420,000 US$ with 14784 patients in 2012. Conclusions: The proposed intervening package changed this clinic to an efficient and economic one. Its income increased 5.08 times and its patient's numbers grew 4.01 times simultaneously. In other words, Mohtasham's experience demonstrates the reliability of the package and its potentiality to be applied in macro level to improve other dentistry clinics. PMID:24627744

  4. The impact of managed care in dentistry.

    1999-01-01

    Managed care plans attempt to control health care expenditures aggressively. These plans directly influence access to medical care and the type, level, and frequency of care rendered. As a result, hospital stays are reduced, focus shifts from inpatient to outpatient care, and patients are responsible for a larger share of health care costs. Dentistry is not immune from the impact of managed care. The attractiveness of the dental market has drawn many managed care organizations, insurers, and entrepreneurs to encourage dentists to participate in a wide variety of managed care programs. However, the delivery of dental care differs markedly in many respects from that of medical care. Therefore, many of the cost saving aspects of managed care that have been so successful in medicine may not result in similar cost savings in dentistry.

    Current projected missions to Mars will require 18 to 24 months of exposure to microgravity conditions, which might have serious effects on human physiology, including that of the oral cavity. Very few studies have been published on the effect of microgravity on the oral cavity, although it has been reported that microgravity increases the prevalence of periodontitis, dental caries, bone loss and fracture in the jaw bone, pain and numbness in teeth and oral cavity tissue, salivary duct stones, and oral cancer. Aeronautic dentistry is a new field, so further study of the effects of microgravity are required. In this article, we review the role of aeronautic dentistry in space missions and offer our recommendations for the future growth of this field.

    This paper reports an exploratory survey study about students' perceptions of learning management systems (LMS) at the Faculty of Dentistry, University of Sydney. Two hundred and fifty-four students enrolled in the Bachelor of Dentistry and the Bachelor of Oral Health programmes participated in an online survey aimed at exploring their beliefs and attitudes as well as their preferences for eLearning tools. Results indicated a strong preference of students for using LMSs as resource repositories rather than for higher-order learning activities such as online discussion forums. This finding holds importance for consideration of the development of the educational resources modalities that support development of essential graduate attributes such as information literacy and collaborative learning.

    The discovery of the induced pluripotent stem (iPS) cell technology, which enables us to produce pluripotent stem cells by introducing a few genetic factors, commands considerable attention in the field of dentistry. These iPS cells may be of particular importance for developing innovative technologies to regenerate missing jaw bones and lost teeth, and there are expectations that several types of tissue stem cells and mucosal cells in the oral area can be used as an ideal iPS cell source. We previously reported that the gingiva, which is often resected during general dental treatments and treated as biomedical waste, is a promising source of iPS cells. In this review, the current trends in iPS cell research in dentistry are outlined, and future aspects of potential applications of the iPS cell technologies to dental treatments will be discussed.

    The processes of development, implementation and perceived usefulness of an objective structured clinical examination in restorative dentistry (OSCE(D)) are reported. An OSCE is a system of assessment. It consists of a set of standardised 'stations'. At each station, a student is tested on a specific clinical task. Each student moves from one station to the next so that by the end of the OSCE, every student has completed every station. The primary purpose of this OSCE was to provide feedback to 49 4th year students on their performance in the clinical areas of conservative dentistry, periodontology and prosthetics. Individual profiles were provided to students and the overall results discussed by staff. There were no significant differences in overall performance between genders or between students in the morning and afternoon examinations. There was a significant difference between performance in prosthetics and the other areas and there were some significant differences among the skill clusters of clinical knowledge, procedures, clinical reasoning, history-taking, techniques and communication. Students and staff perceived the OSCE(D) as a valuable tool for providing feedback. The development of the OSCE and the findings described in this paper will be of value to clinical staff who are developing OSCEs in all areas of dentistry.

    The objective of this study was to systematically assess the informational value, intention, source, and bias of videos related to dentistry available on the video-sharing Internet platform YouTube. YouTube (www.youtube.com) was searched for videos related to dentistry, using the system-generated sorts "by relevance" and "most viewed" and two categories (All and Education). Each of the first thirty results was rated by two assessors filling out a questionnaire for each (total: 120). The data were subjected to statistical analysis using Cohen's kappa, Pearson's correlation coefficient tau, Mann-Whitney U-tests, and a nonparametric three-way ANOVA, including an analysis of the interaction between the sorting and category effect, with an α-level of 5 percent. The scan produced 279,000 results in the category All and 5,050 in the category Education. The analysis revealed a wide variety of information about dentistry available on YouTube. The purpose of these videos includes entertainment, advertising, and education. The videos classified under Education have a higher degree of usefulness and informational value for laypersons, dental students, and dental professionals than those found in a broader search category. YouTube and similar social media websites offer new educational possibilities that are currently both underdeveloped and underestimated in terms of their potential value. Dentists and dental educators should also recognize the importance of these websites in shaping public opinion about their profession.

    Warren Estates-Manzanita Estates is the largest privately-owned and operated residential geothermal district heating system in the State of Nevada. The system has operated for ten years and presently services 95 homes. Geothermal energy is used to heat homes, domestic water, spas, swimming pools, and greenhouses. Four homes have installed driveway deicing systems using geothermal energy. This paper briefly describes the geothermal resource, wells, system engineering, operation, applications, and economics. The accompanying posters illustrate the geothermal area, system design, and various applications. The resource is part of the Moana geothermal field, located in southwest Reno. Excluding the Warren-Manzanita Estates, the well-known Moana field supports nearly 300 geothermal wells that supply fluids to individual residences, several motels, a garden nursery, a few churches, and a municipal swimming pool. The Warren-Manzanita Estates is ideally suited for residential district space heating because the resource is shallow, moderate-temperature, and chemically benign. The primary reservoir rock is the Kate Peak andesite, a Tertiary volcanic lahar that has excellent permeability within the narrow fault zones that bisect the property. The Kate Peak formation is overlain by impermeable Tertiary lake sediments and alluvium. Two production wells, each about 240 m deep, are completed near the center of the residential development at the intersection of two fault zones. Geothermal fluids are pumped at a rate of 15 to 25 l/s (260-400 gpm) from one of two wells at a temperature of 95{degrees}C (202{degrees}F) to two flat-plate heat exchangers. The heat exchangers transfer energy from the geothermal fluids to a second fluid, much like a binary geothermal power plant.

    Organic compounds studied in this U.S. Geological Survey (USGS) assessment generally are man-made, including, in part, pesticides, solvents, gasoline hydrocarbons, personal care and domestic-use products, and refrigerants and propellants. Of 258 compounds measured, 28 were detected in at least 1 source water sample collected approximately monthly during 2002-05 at the intake of the Chalk Bluff Treatment Plant, on the Truckee River upstream of Reno, Nevada. The diversity of compounds detected indicate various sources and uses (including wastewater discharge, industrial, agricultural, domestic, and others) and different pathways (including point sources from treated wastewater outfalls upstream of the sampling location, overland runoff, and groundwater discharge) to drinking-water supply intakes. Three compounds were detected in more than 20 percent of the source-water intake samples at low concentrations (less than 0.1 microgram per liter), including caffeine, p-cresol (a wood preservative), and toluene (a gasoline hydrocarbon). Sixteen of the 28 compounds detected in source water also were detected in finished water (after treatment, but prior to distribution; 2004-05). Additionally, two disinfection by-products not detected in source water, bromodichloromethane and dibromochloromethane, were detected in all finished water samples. Two detected compounds, cholesterol and 3-beta-coprostanol, are among five naturally occurring biochemicals analyzed in this study. Concentrations for all detected compounds in source and finished water generally were less than 0.1 microgram per liter and always less than human-health benchmarks, which are available for about one-half of the compounds. Seven compounds (toluene, chloroform, bromodichloromethane, dibromodichloromethane, bisphenol A, cholesterol, and 3-beta-coprostanol) were measured at concentrations greater than 0.1 microgram per liter. On the basis of this screening-level assessment, adverse effects to human health are

    In 2 earlier articles a definition of professionalism was developed, and several specific professional responsibilities were deduced. This third and final article in the series examines whether dentistry qualifies as a profession. On various levels, the professionalism of dentistry is found wanting. However, attaining the status of a profession is a work in progress, which means that each profession will always have some deficiencies. The author concludes that dentistry qualifies as a profession but that it is also exhibiting a trend toward once again becoming a business (as it was before the 19th century). For the sake of honesty with the public, dentistry must make a choice between these 2 models.

    Children's dentistry can be a challenge for both the patient and the dentist. The way a dentist interacts with the child patient will have a major influence on the success of any clinical or preventive care. In order to deliver high-quality dentistry to a child whilst also developing a positive attitude towards dental health, the dentist should have a good understanding of the factors that might affect the behaviour of children in the dental setting. A working knowledge of strategies to minimize anxiety and make positive behaviour more likely is essential, as is a grasp of how best to deal with anxiety or negative behaviour.

    2011-10-01

    Oral fluid-based (salivary) tests have the potential to create practical, point-of-care clinical instruments that are convenient, practical, and comfortable to use in dentistry and medicine. Currently, there are no simple, accurate, and inexpensive sampling, screening, or detection methods to support definitive diagnostic platforms across dental and medical disciplines. Though the benefits from advancing screening and detection technologies seem eminent, analytical, chemical, molecular, genetic, and protein markers are still under development. Clinical applications in patient care must be validated independently to ensure that they are clinically accurate, reliable, precise, and uniformly consistent for screening and detecting specific diseases or conditions. As technology designed to improve patient care through risk assessment, prevention, and disease management is transferred into clinical practice, dentistry may need to reassess its role in general health care.

    Celiac trunk aneurysm is one of the rarest forms of splanchnic artery aneurysm. Conventional open vascular surgery is associated with increased rates of morbidity and mortality and can require complex vascular reconstruction.We describe the case of a 42-year-old patient with celiac trunk aneurysm whom we treated by means of a hybrid surgical-endovascular procedure. We performed a left reno-splenic bypass, after which we used a direct splenic artery approach to deploy a self-expandable 6 × 50-mm stent-graft across the splenic and hepatic arteries. One year later, the stability of the repair was confirmed.

Conventional open vascular surgery is associated with increased rates of morbidity and mortality and can require complex vascular reconstruction. We describe the case of a 42-year-old patient with celiac trunk aneurysm whom we treated by means of a hybrid surgical-endovascular procedure. We performed a left reno-splenic bypass, after which we used a direct splenic artery approach to deploy a self-expandable 6 × 50-mm stent-graft across the splenic and hepatic arteries. One year later, the stability of the repair was confirmed. PMID:22719156

    Inspired by recently published NDA II: The Story of America's Second National Dental Association and sponsored jointly by the National Dental Association Foundation and the Colgate-Palmolive Company, an historical exhibit on dentistry in the African-American community was one of the celebrations for the Golden Anniversary of the American Academy of the History of Dentistry. This exhibit premiered on Sept. 27, 2002 in the National Museum of Dentistry located on the medical/dental campus of the University of Maryland in Baltimore. The Museum recently became an affiliate of the Smithsonian Institution. Contents of the exhibit were photographs, charts, artifacts, memorabilia, etc. These materials presented an overview of African-American activities in dental education, research, patient care, general practice, dental specialities, military service, and public health. Also included were inter-racial relationships, socioeconomic developments, and participation in civil rights endeavors that played a major role in changing out-dated accepted customs. The exhibit's purpose was to celebrate dentistry's ministrations as a health professional among African Americans in particular and the nation at large over the past two centuries. Respect for and progress of black dentists paralleled that of black physicians who were instrumental in including dentist and pharmacists as equal members in the National Medical Association since the latter's inception in 1895.

  11. Professionalism: challenges for dentistry in the future.

    PubMed

    While countries varies significantly in the financing of dental care, they are much more alike in the delivery of dentistry. Dental care is principally provided in dental offices and clinics that are independent business entities whose business leaders are most often the dentists themselves. However society expects from dentists a level of professionalism (i.e. habitually acting ethically, both in terms of competence and conduct) in contrast to the methods and motivations of the marketplace. This is why the single most important challenge of dental professional ethics continues to be giving proper priority to patients' well being and building ethically correct decision-making relationships with patients while, at the same time, trying to maintain a successful business operation. If we look into dentistry's future, the centrality of this aspect of professional ethics is not likely to change, although the ways in which dentists might violate this trust will probably multiple as funding mechanisms become increasingly complex. It is important that dentists reflect with fresh eyes on their ethical commitments. One challenge is the increased availability of oral health information to the public and the fact that so many people are uncritical of the accuracy of information in the media and on the web. A second is the increase in the amount of health care advertising in many societies. A third is the growth of aesthetic dentistry that differs from standard oral health care in important and ethically significant ways. The fourth is insurance that frequently complicates the explanation of a patient's treatment alternatives and often brings a third party into the treatment decision relationship. The ethical challenges of each of these factors will be considered and ultimately tying it to the central theme of dental professionalism.

    Induced pluripotent stem cells (iPSCs), a path-breaking invention, have revolutionized the regenerative medicine field. The biggest advantage of this technology is its patient-specific nature and so it is nonimmunogenic. It involves autologous tissues with limitless source of cells throughout life. The Nobel-winning concept involves the reprograming of terminally differentiated cells by external factors and has a tremendous role in the treatment of genetic disorders, regeneration of tissues, drug discovery, and disease modeling. This short review aims at the probable applications of iPSC technology in dentistry with respect to regeneration of oral and maxillofacial tissues and also its role in oral malignancies.

    This paper summarizes three recent applications of computer vision techniques in dentistry developed at the Czech Technical University. The first one uses a special optical instrument to capture the image of the tooth arc directly in the patient's mouth. The captured images are used for visualization of teeth position changes during treatment. The second application allows the use of images for checking teeth occlusal contacts and their abrasion. The third application uses photometric measurements to study the resistance of the dental material against microbial growth.

    The human body comprises molecules; hence, the availability of molecular nanotechnology will permit dramatic progress to address medical problems and will use molecular knowledge to maintain and improve human health at the molecular scale. Nanomedicine could develop devices that are able to work inside the human body in order to identify the early presence of a disease, and to identify and quantify toxic molecules and tumor cells, for example. Nanodentistry will make possible the maintenance of comprehensive oral health by employing nanomaterials, including tissue engineering and, ultimately, dental nanorobots. This review is an attempt to highlight the possible applications of nanotechnology and the use of nanomaterials in dentistry. PMID:22131826

    Herbs are staging a comeback and herbal ‘renaissance’ is happening all over the globe. The herbal products, today, symbolize safety, in contrast to the synthetics that are regarded as unsafe to humans and the environment. A herb, botanically speaking, is any plant that lacks the woody tissue which is characteristic of shrubs or trees. More specifically, herbs are plants which are used medicinally or for their flavour or scent. Herbs with medicinal properties are a useful and an effective source of treatment for various disease processes. Herbal extracts have been successfully used in dentistry as tooth cleaning and antimicrobial plaque agents. The use of herbal medicines continues to expand rapidly across the world. Many people take herbal medicines or herbal products now for their health care in different national healthcare settings. Herbal extracts have been used in dentistry for reducing inflammation, as antimicrobial plaque agents, for preventing release of histamine and as antiseptics, antioxidants, antimicrobials, antifungals, antibacterials, antivirals and analgesics. They also aid in healing and are effective in controlling microbial plaque in gingivitis and periodontitis, thereby improving immunity. PMID:24086929

    Holography offer new nondestructive possibilities for bridging the gap between in vitro and in vivo measurements in dentistry, and thus increase the possibility of achieving more accurate and sometimes more objective diagnosis and therapy. The use of stone and plaster study models is an integral part of any dental practice and is required for research. Storage of study models is problematic in terms of space and cost. Various methods have been employed in the threedimensional (3D) assessment and recording of dental study models. These include Holography and Moire Topography. Holography was introduced in 1948. However, it was the work of Leith & Upatnieks that revolutionized holography with the application of the laser beam. Holography allows direct measurement of 3D displacements of a few micrometres. The major problem with this technique is the poor quality of recording the details of the study models, particularly in the incisor region. An advantage of holography is that films may be stored with medical records and it is a further step towards archiving dental study models. However, it cannot totally replace the original models. The aim of this study is to present the possibility to record dental models in holograms and to develop direct measurement on these. Key words: dentistry, dental model, holograms, fixed partial dentures, optical coherence tomography.

    By definition and general agreement, smart materials are materials that have properties which may be altered in a controlled fashion by stimuli, such as stress, temperature, moisture, pH, and electric or magnetic fields. There are numerous types of smart materials, some of which are already common. Examples include piezoelectric materials, which produce a voltage when stress is applied or vice versa, shape memory alloys or shape memory polymers which are thermoresponsive, and pH sensitive polymers which swell or shrink as a response to change in pH. Thus, smart materials respond to stimuli by altering one or more of their properties. Smart behaviour occurs when a material can sense some stimulus from its environment and react to it in a useful, reliable, reproducible, and usually reversible manner. These properties have a beneficial application in various fields including dentistry. Shape memory alloys, zirconia, and smartseal are examples of materials exhibiting a smart behavior in dentistry. There is a strong trend in material science to develop and apply these intelligent materials. These materials would potentially allow new and groundbreaking dental therapies with a significantly enhanced clinical outcome of treatments. PMID:24672407

    One of the greatest figures in the development of the dental profession to the high status it enjoys today is all but forgotten. Jonathan Taft was dean of the second dental school in the world and wrote the most important clinical textbook of his time, one that was reprinted in many editions over a quarter of a century. Later appointed dean of the new University of Michigan Dental School, he instituted innovations in admission requirements and course of study that were copied by all subsequent schools and are the standards adhered to today. The editor of one of the most important dental journals for 44 years, a record unmatched to this day, he set the standards for modern dental periodical literature that have done so much to elevate dentistry that today it stands on a par with medicine as a truly science-based profession. He served dentistry in many capacities: president of the American Dental Association, founder of the National Association of Dental Faculties, and founder of the National Association of Dental Examiners. Over his lifetime, he published almost 200 professional papers and probably attended and lectured at more dental meetings than anyone of his day and since. His memory should be resurrected, and the profession must be made aware of the great debt it owes to this intrepid fighter for a better dental profession.

Sometimes we get complains of sensitive teeth and sometimes of tired facial muscles on getting up in the morning. Owing to the intimate relation of masticatory apparatus with the cranium and cervico-scapular muscular system, the disorders in any system, draw attention from concerned clinicians involved in management, to develop an integrated treatment protocol for the suffering patients. There may be patients reporting to the dental clinics after an occlusal restoration or extraction, having pain in or around the temporomandibular joint, headache or neck pain. Although their esthetic demands must not be undermined during the course of treatment plan, whenever dental treatment of any sort is planned, occlusion/bite should be given prime importance. Very few dentist are able to diagnose the occlusal disease and of those who diagnose many people resort to aggressive treatment modalities. This paper aims to report the signs of occlusal disease, and discuss their association with TMDs and posture.

    In 2007, only four years after the completion of the Human Genome Project, the journal Science announced that epigenetics was the 'breakthrough of the year'. Time magazine placed it second in the top 10 discoveries of 2009. While our genetic code (i.e. our DNA) contains all of the information to produce the elements we require to function, our epigenetic code determines when and where genes in the genetic code are expressed. Without the epigenetic code, the genetic code is like an orchestra without a conductor. Although there is now a substantial amount of published research on epigenetics in medicine and biology, epigenetics in dental research is in its infancy. However, epigenetics promises to become increasingly relevant to dentistry because of the role it plays in gene expression during development and subsequently potentially influencing oral disease susceptibility. This paper provides a review of the field of epigenetics aimed specifically at oral health professionals. It defines epigenetics, addresses the underlying concepts and provides details about specific epigenetic molecular mechanisms. Further, we discuss some of the key areas where epigenetics is implicated, and review the literature on epigenetics research in dentistry, including its relevance to clinical disciplines. This review considers some implications of epigenetics for the future of dental practice, including a 'personalized medicine' approach to the management of common oral diseases.

    Several branches of competence are needed to evaluate malpractice in dentistry: first a complete case history, secondly careful clinical observation and finally a correct procedure of radiographic documentation. This latter is able to prove existence of the treatment and its evolution, moreover it shows the bone, the dental components underneath the surface and the treatment becomes appraisable by different observers. In restorative dentistry, radiological findings allow us to demonstrate overcontoured restorations in approximal sites and, if necessary, identify the biological width. In endodontics the insufficient filling or the overfilling of the root channel can be demonstrated along with the material used for the filling and the presence of fractured instruments inside the channel. In prosthodontics, on the other hand, the quality of the abutments, fractured roots and/or prosthesis, symptoms of inadequate charge on the bone and overcontours with the subsequent periodontal damage can be seen. In orthodontics one can assess the appearance of infrabone pockets, reabsorptions and horizontal recessions. In extractive surgery it is again possible to identify through radiographic documentation small root fragments in the maxillary sinus (possible sinusitis associated) and maxillary fractures as a consequence of extractions. In the field of implantology, damage to noble structures due to inadequate case planning can be highlighted.

    In medicine stem cell–based treatments are being used in conditions like Parkinson's disease, neural degeneration following brain injury, cardiovascular diseases, diabetes, and autoimmune diseases. In dentistry, recent exciting discoveries have isolated dental stem cells from the pulp of the deciduous and permanent teeth, from the periodontal ligament, and an associated healthy tooth structure, to cure a number of diseases. The aim of the study was to review the applications of stem cells in various fields of dentistry, with emphasis on its banking, and to understand how dental stem cells can be used for regeneration of oral and non-oral tissues conversely. A Medline search was done including the international literature published between 1989 and 2011. It was restricted to English language articles and published work of past researchers including in vitro and in vivo studies. Google search on dental stem cell banking was also done. Our understanding of mesenchymal stem cells (MSC) in the tissue engineering of systemic, dental, oral, and craniofacial structures has advanced tremendously. Dental professionals have the opportunity to make their patients aware of these new sources of stem cells that can be stored for future use, as new therapies are developed for a range of diseases and injuries. Recent findings and scientific research articles support the use of MSC autologously within teeth and other accessible tissue harvested from oral cavity without immunorejection. A future development of the application of stem cells in interdisciplinary dentistry requires a comprehensive research program. PMID:23919198

    Objective: The purpose of this study was to review the uses of electromyography (EMG) in dentistry in the last few years in related research. EMG is an advanced technique to record and evaluate muscle activity. In the previous days, EMG was only used for medical sciences, but now EMG playing a tremendous role in medical as well as dental sector. Materials and Methods: Several electronic databases such as Google Scholar, PubMed, Science Direct, and Web of Science were systematically searched for studies published until July 2015. Results: EMG can be used in both diagnosis and treatment purpose to record neuromuscular activity. In dentistry, we can utilize EMG to evaluate muscular activity in function such as chewing and biting or parafunctional activities such as clenching and bruxism. In case of TMJ and myofascial pain disorders, EMG widely is used in the last few years. Conclusions: EMG is one of biometric tests that occur in the modern evidence-based dentistry practice.

    There has been limited research into the impact of predoctoral experiences and postdoctoral general dentistry residencies on the practice patterns of dentists in the care of patients with special or complex needs. This study was undertaken to determine if educational experiences with special populations had a relationship to practice patterns after graduation or residency. University of the Pacific alumni who graduated between 1997 and 2007 were surveyed regarding their pre- and postdoctoral dental education and their practice patterns for the care of patients categorized as medically compromised, frail elders, and developmentally disabled. Definitions for each patient category were provided. Alumni were asked about their practice setting and postdoctoral education. Thirty-one percent (n=526) of those surveyed responded. Regression analyses showed respondents not in private practice were more likely to have completed a postdoctoral general dentistry program (Advanced Education in General Dentistry or General Practice Residency) after dental school compared to respondents in private practice (p<0.001). Across all age groups, respondents not in private practice treated significantly more patients with developmental disabilities than those in private practice (p<0.001). Respondents not in private practice treated more medically compromised patients younger than age sixty-five compared to respondents in private practice (p<0.01). Interestingly, those in private practice treated significantly more patients over sixty-five who were also classified as medically compromised (p<0.05). Pacific alumni who completed postdoctoral training in general dentistry were found to practice more often in non-private practice settings. Alumni in non-private practice settings reported treating a higher percentage of medically compromised patients below age sixty-five than their counterparts in a typical private practice.

  11. Payment systems and incentives in dentistry.

    PubMed

    Grytten, Jostein

    2016-11-03

    In this commentary, we discuss the advantages and disadvantages of the following incentive-based remuneration systems in dentistry: fee-for-service remuneration, per capita remuneration, a mixed payment system (a combination of fee-for-service remuneration and per capita remuneration) and pay-for-performance. The two latter schemes are fairly new in dentistry. Fee-for-service payments secure high quality, but lead to increased costs, probably due to supplier-induced demand. Per capita payments secure effectiveness, but may lead to under-treatment and patient selection. A mixed payment scheme produces results somewhere between over- and under-treatment. The prospective component (the per capita payment) promotes efficiency, while the retrospective component (the fee-for-service payment) secures high quality of the care that is provided. A pay-for-performance payment scheme is specifically designed towards improvements in dental health. This is done by linking provider reimbursements directly to performance indicators measuring dental health outcomes and quality of the services. Experience from general health services is that pay-for-performance payment has not been very successful. This is due to significant design and implementation obstacles and lack of provider acceptance. A major criticism of all the incentive-based remuneration schemes is that they may undermine the dentists' intrinsic motivation for performing a task. This is a crowding-out effect, which is particularly strong when monetary incentives are introduced for care that is cognitively demanding and complex, for example as in dentistry. One way in which intrinsic motivation may not be undermined is to introduce a fixed salary component into the remuneration scheme. Dentists would then be able to choose their type of contract according to their abilities and their preferences for nonmonetary rewards as opposed to monetary rewards. If a fixed salary component cannot be introduced into the remuneration

    The purpose of this work is to assess, both experimentally and theoretically the status of air quality in a dentistry clinic of the Athens University Dentistry Faculty with respect to chemical pollutants and identify the indoor sources associated with dental activities. Total VOCs, CO(2), PM(10), PM(2.5), NO(x) and SO(2) were measured over a period of approximately three months in a selected dentistry clinic. High pollution levels during the operation hours regarding CO(2), total VOCs and Particulate Matter were found, while in the non-working periods lower levels were recorded. On the contrary, NO(x) and SO(2) remained at low levels for the whole experimental period. These conditions were associated with the number of occupants, the nature of the dental clinical procedures, the materials used and the ventilation schemes, which lead to high concentrations, far above the limits that are set by international organizations and concern human exposure. The indoor environmental conditions were investigated using the Computational Fluid Dynamics (CFD) model PHOENICS for inert gases simulation. The results revealed diagonal temperature stratification and low air velocities leading to pollution stratification, accompanied by accumulation of inert gaseous species in certain areas of the room. Different schemes of natural ventilation were also applied in order to examine their effect on the indoor comfort conditions for the occupants, in terms of air renewal and double cross ventilation was found to be most effective. The relative contribution of the indoor sources, which are mainly associated with indoor activities, was assessed by application of the Multi Chamber Indoor Air Quality Model (MIAQ) to the experimental data. It was found that deposition onto indoor surfaces is an important removal mechanism while a great amount of particulate matter emitted in the Clinic burdened severely the indoor air quality.

    In the early years of the new millennium, the National Institute of Dental and Craniofacial Research of the National Institutes of Health began funding Oral Health Research Education Grants using the R25 mechanism to promote the application of basic and clinical research findings to clinical training and to encourage students to pursue careers in oral health research. This report describes the impact of an R25 grant awarded to the Texas A&M Health Science Center’s Baylor College of Dentistry (BCD) on its curriculum and faculty development efforts. At BCD, the R25 grant supports a multipronged initiative that employs clinical research as a vehicle for acquainting both students and faculty with the tools of evidence-based dentistry (EBD). New coursework and experiences in all four years of the curriculum plus a variety of faculty development offerings are being used to achieve this goal. Progress on these fronts is reflected in a nascent EBD culture characterized by increasing participation and buy-in by students and faculty. The production of a new generation of dental graduates equipped with the EBD skill set as well as a growing nucleus of faculty members who can model the importance of evidence-based practice is of paramount importance for the future of dentistry.

    Our second part of the publication entitled "The image of Dentistry" discusses the properties that correspond to the ideal image of dentistry or even the ideal scientist such as the management of the dental practice, the dentist-patient relationship and the appropriate handling of the patient's emotions such as anxiety or pain. The quality of treatment and the friendly, honest and compassionate attitude of the dentist can immediately affect the image of dentistry. Therefore, the dental professional must try to keep the balance between practice profit, staffing and patient well-being in order to fulfill both social and public health responsibilities.

  15. Occupational health problems in modern dentistry: a review.

    Despite numerous technical advances in recent years, many occupational health problems still persist in modern dentistry. These include percutaneous exposure incidents (PEI); exposure to infectious diseases (including bioaerosols), radiation, dental materials, and noise; musculoskeletal disorders; dermatitis and respiratory disorders; eye injuries; and psychological problems. PEI remain a particular concern, as there is an almost constant risk of exposure to serious infectious agents. Strategies to minimise PEI and their consequences should continue to be employed, including sound infection control practices, continuing education and hepatitis B immunisation. As part of any infection control protocols, dentists should continue to utilise personal protective measures and appropriate sterilisation or other high-level disinfection techniques. Aside from biological hazards, dentists continue to suffer a high prevalence of musculoskeletal disorders (MSD), especially of the back, neck and shoulders. To fully understand the nature of these problems, further studies are needed to identify causative factors and other correlates of MSD. Continuing education and investigation of appropriate interventions to help reduce the prevalence of MSD and contact dermatitis are also needed. For these reasons, it is therefore important that dentists remain constantly informed regarding up-to-date measures on how to deal with newer technologies and dental materials.

  16. The feminization of dentistry: implications for the profession.

    Over the last 40 years, the proportion of women in dentistry has been rising steadily, raising questions about the effects of this feminization on the profession. A review of the literature, although limited, highlights potentially important areas related to gender, including impact on work hours, practice models, professional incomes, the dentist-patient relationship, clinical philosophies, specialty practice, academia and leadership. Although cohorts of predominantly female dentists are only beginning to enter the workforce and, thus, it is difficult to predict the long-term effects, some trends are evident: women are less likely than men to own their practice; women may work 4-6 fewer hours a week and see fewer patients; there is a pay differential; female general practitioners and specialists appear more likely to work in urban centres; and women are less prominent in the specialties, academia and leadership roles. Thus, the profession may shift toward less entrepreneurship, more urbanization and, possibly, fewer clinical hours available to the population as a result of feminization. With the ultimate goal of excellence in patient care, this may entail increases in student enrolment, formal incentives for practice relocation to rural communities, more business education and policies to modify advanced education and training for women with children. This knowledge, although still not robust, is relevant for policy, educational institutions and professional governing bodies.

    Nanotechnology influences almost every facet of everyday life from security to medicine. The concept of nanotechnology is that when one goes down to the bottom of things, one can discover unlimited possibilities and potential of the basic particle. In nanotechnology, analysis can be made to the level of manipulating atoms, molecules and chemical bonds between them. The growing interest in the dental applications of nanotechnology is leading to the emergence of a new field called nanodentistry. An electronic database search that included PubMed, MedLine, and Cochrane library was conducted. Key words used in the search are nanotechnology dentistry and applications. Language limitation was set as articles reviewed were only those written and published in English language. We did not search the gray literature. Initially, 52 articles were retrieved from the database, and articles considered were those published from 2008 to 2013. Eight articles that met the selection criteria were eventually selected and reviewed. PMID:25364585

    The problem of spatial recording and analysing of mandibular movements was always of interest in dentistry. The permanent development of new technologies has resulted in a wide range of various methods and measuring systems for recording mandibular movements. However, only some of them have fulfilled a greater number of evaluation demands of modern measuring systems, which permit their industrial production. The paper discusses electrognathography as one of the most up-to-date methods widely used in the study of mandibular kinetics. The principles, performance and various possibilities of use of the two commercial electrognathographic apparatuses, now present on the world market, are presented. They are Sirognathograph (Siemens A.G., Bensheim, W. Germany) and Mandibular Kinesiograph (Myo-tronics Research, Seattle, U.S.A.)

    In recent years, a new class of drugs has revolutionized the treatment of autoimmune, allergic, infectious, and many more diseases. This new class of drugs is made of 3 groups-cytokines, monoclonal antibodies, and fusion proteins-that may target special damaged cells but not all the cells. These drugs may have side effects such as infection, hypersensitivity, hematologic disorders, cancer, hepatotoxicity, and neurologic disorders. However, there is not enough evidence or long-term studies of the mechanism of action and side effects of these drugs. Patients receiving biological therapies may need special consideration in dentistry. This paper is a review of the classification, mechanism of action, and side effects of these drugs and dental consideration for patients receiving biological therapies.

    As the population ages and life expectancy increases, clinicians today find themselves in the wake of an ever-growing demand for high-quality aesthetic dental treatment, by increasingly informed patients. The long-term success of both cosmetic and restorative dentistry is dependent on well designed restorations and the health of the periodontal tissues. Overhanging restorations, full crown restorations with poor marginal fit, and implant-supported prosthetics with inadequate hygiene access all increase the risk for periodontal sequelae and interproximal caries. When planning restorative treatment, consideration should be given to the restorative design, the need for hygiene access and the location of intended implants. In addition, the patient's manual dexterity and ability to manipulate oral hygiene aids is a crucial consideration, as is adequate access for the hygienist to manually debride and maintain the restorations.

    Long-acting local anesthetics have proved to be effective for the suppression of both intraoperative and postoperative pain. They are useful for lengthy dental treatments and for prevention of severe pain following many types of surgical procedures. Although the currently available long-acting local anesthetics for dentistry have minimal side effects in the doses usually employed, there are potential problems. Bupivacaine, for example, can cause significant cardiac depressant and dysrhythmogenic responses. Etidocaine has less pronounced effects on the cardiovascular system, but its use may be associated with inadequate control of intraoperative bleeding. A new long-acting local anesthetic, ropivacaine, appears to offer advantages over either of the currently used long-acting agents. PMID:1308373

    2006-09-01

    HIV transmission in the health-care setting is of concern. To assess the current position in dentistry, we have reviewed the evidence to November 1, 2005. Transmission is evidently rare in the industrialized nations and can be significantly reduced or prevented by the use of standard infection control measures, appropriate clinical and instrument-handling procedures, and the use of safety equipment and safety needles. We hope that breaches in standard infection control will become vanishingly small. When occupational exposure to HIV is suspected, the application of post-exposure protocols for investigating the incident and protecting those involved from possible HIV infection further reduces the likelihood of HIV disease, and also stress and anxiety.

    Human differences in disease phenotype and treatment responses are well documented. Technological advances now allow healthcare providers to improve the prevention and treatment of chronic diseases by stratifying patient populations. Although personalized medicine has great promise, it has, so far, been primarily applied in oncology. Wider adoption requires changes in the healthcare system and in clinical decision-making, and early applications of personalized medicine appear to require strong clinical utility and sufficient value to drive adoption. Personalized medicine is likely to enter dentistry as patients start to demand it and as new drugs are developed for pathways common to oral diseases.

    Background: The Journal of Conservative Dentistry (JCD) has been online since 2008. Materials and Methods: This paper reviews the publication in this journal over a 5-year period (2011–2015). It assesses the types of articles published, coverage of various types of subjects of endodontics, and conservative dentistry in the journal and explores the authorship patterns in the publication and citation of the journal over this period. Results and Conclusion: JCD has delivered broad-based, balanced coverage of endodontics and conservative dentistry between 2011 and 2015, with contributions from all over India, as well as abroad. Although a maximum number of articles were from India, the publications from other countries are also on an increase. Thus, the widespread coverage of this journal suggests that JCD has begun to represent the global face of the Indian Association of Conservative Dentistry and Endodontics. PMID:27656069

    Dr. Newell Sill Jenkins was one of the pioneer American dentists who took "American dentistry" to Europe. Among his patients were Composer Richard Wagner, and among his friends, Author Mark Twain. He treated some of the crown head of Europe, and yet found time to participate in organized dentistry and conduct research in cosmetic dentistry. He was the father of the porcelain revival in both Europe and America. Unfortunately, Jenkins' Legacy as the chief proponent of cosmetic dentistry in the late 19th and early 20th centuries has been largely ignored by dental historians. In a 20-year period (1896 to 1916), Jenkins published 32 articles in the dental literature on the esthetic advantages of porcelain fillings. It is time to give Jenkins his just recognition.

    A brief survey of the scientific and clinical literature (1990-present) on occupational hazards in dentistry is presented. The hazards identified are associated with chemical and biological agents. Yet, dentistry is a relatively safe profession. Other adverse health risks arise as new technologies and materials are developed. However, once identified and recognized as a risk, new guidelines, precautions and protocols are rapidly instituted to greatly reduce or even eliminate the occupational hazard.

    Objectives: Determine the domain of preventive dentistry in nursing personnel assigned to a primary care unit. Methods: Prospective descriptive study, questionnaire validation, and prevalence study. In the first stage, the questionnaire for the practice of preventive dentistry (CPEP, for the term in Spanish) was validated; consistency and reliability were measured by Cronbach's alpha, Pearson's correlation, factor analysis with intra-class correlation coefficient (ICC). In the second stage, the domain in preventive dental nurses was explored. Results: The overall internal consistency of CPEP is α= 0.66, ICC= 0.64, CI95%: 0.29-0.87 (p >0.01). Twenty-one subjects in the study, average age 43, 81.0% female, average seniority of 12.5 were included. A total of 71.5% showed weak domain, 28.5% regular domain, and there was no questionnaire with good domain result. The older the subjects were, the smaller the domain; female nurses showed greater mastery of preventive dentistry (29%, CI95%: 0.1-15.1) than male nurses. Public health nurses showed greater mastery with respect to other categories (50%, CI95%: 0.56-2.8). Conclusions: The CDEP has enough consistency to explore the domain of preventive dentistry in health-care staff. The domain of preventive dentistry in primary care nursing is poor, required to strengthen to provide education in preventive dentistry to the insured population. PMID:25386037

    Background Several controversies exist about the methods of harvesting and eventual utilization of stem cells in Medicine and Dentistry. The objective of the study was to investigate the awareness, attitude and knowledge of the use of stem cells in Dentistry among Nigerian Dentists. Methods This descriptive, cross-sectional study was conducted among dentists selected from both private and public health sectors, in some of the major cities in Nigeria. Results The majority of the participants were ≤35 years in age, male, Pentecostal Christians, possessed a postgraduate qualification, had practiced for ≤5 years and were specialists or specializing. In this study, 153(81.0%) of the participants reported awareness about the use of stem cells in dentistry which was significantly associated with qualification and type of practice. Most of the respondents 114 (60.3%) had a poor knowledge of the use of stem cells in Dentistry. This was significantly associated with type of practice and awareness about stem cell use in dentistry but binary logistic regression showed awareness as the only determinant of knowledge. About three-quarters 142 (75.1%) of the participants exhibited positive attitude towards stem cell use. This had a positive non-significant association with knowledge and reported awareness. Conclusion Data from this study revealed a high level of awareness, positive attitude to and poor knowledge of the use of stem cells in Dentistry among a cross section of Nigerian Dentists.

The imperialist Japan licensed the dental technicians (yipchisa) without limit and controlled them generously so they could practice dentistry freely. This measure was contrary to that in Japan. (In Japan no new dental technician was licensed.) Komori, a dental technician opened his laboratory at Chungmuro in 1902. The dental technician had outnumbered by 1920. In 1907, the first Korean dental technician Sung-Ryong Choi practiced dentistry in Jongno. The imperialist Japan made the regulations for dental technicians to set a limit to the advertisement and medical practice of dental technicians. The first Korean dentists Suk-Tae Ham was register No. 1 in the dentist license. The Kyungsung dental school was established by Nagira Dasoni for the purpose of educating some Korean people that contributed to Japanese colonization. It made progress with the help of Japan, it was was given the approval of the establishment of the professional school in January the 25th, 1929. It was intended to produce Korean dentists in the first place but became the school for Japanese students later on. The association of Chosun dentist, which had been founded by Narajaki doyoyo, was managed by Japanese dentists in favor of the colonial ruling. The Hansung Association of Dentists established in 1925 was the organization made by the necessity of the association for Koreans only. The Japanese forcefully annexed the Association of Hansung Dentists (Koreans only) to the Association of Kyungsung Dentists to avoid collective actions of Korean dentists in the name of 'Naesunilche' -- 'Japan and Korea and one'. Their invading intention was shown in the event of 'decayed tooth preventive day'. Japanese controlled

    Acetylation of histone and non-histone proteins alters gene expression and induces a host of cellular effects. The acetylation process is homeostatically balanced by two groups of cellular enzymes, histone acetyltransferases (HATs) and histone deacetylases (HDACs). HAT activity relaxes the structure of the human chromatin, rendering it transcriptionally active, thereby increasing gene expression. In contrast, HDAC activity leads to gene silencing. The enzymatic balance can be 'tipped' by histone deacetylase inhibitors (HDACi), leading to an accumulation of acetylated proteins, which subsequently modify cellular processes including stem cell differentiation, cell cycle, apoptosis, gene expression, and angiogenesis. There is a variety of natural and synthetic HDACi available, and their pleiotropic effects have contributed to diverse clinical applications, not only in cancer but also in non-cancer areas, such as chronic inflammatory disease, bone engineering, and neurodegenerative disease. Indeed, it appears that HDACi-modulated effects may differ between 'normal' and transformed cells, particularly with regard to reactive oxygen species accumulation, apoptosis, proliferation, and cell cycle arrest. The potential beneficial effects of HDACi for health, resulting from their ability to regulate global gene expression by epigenetic modification of DNA-associated proteins, also offer potential for application within restorative dentistry, where they may promote dental tissue regeneration following pulpal damage.

    After major disasters such as earthquakes, fires, floods, tsunami, bomb blasts or terrorist attacks, accurate, and early identification of the dead and injured becomes an utmost importance. Restorations, cariesteeth, missingteeth and/or prostheses are most useful aids for the dental identification. At times, only identifiable remains are a victim's partial or complete dentures. The central principle of dental identification is that postmortem dental remains can be compared with antemortem dental records which include, studycasts, radiographs, etc., to confirm the identity of the victims. Marking/labeling dentures have been considered an important aid in forensic dentistry. Other than finger printing, when compared with all the methods, the marking/labeling of dentures is an accurate and rapid method to identify the unknown victims. There are no standardized methods to follow, but dental practitioners needs to maintain some dental records of their patients. This may include documentation of the "marking of dentures." The preparedness is the key to success in mass disaster identification. The aim of this review article is to discuss the methods of denture identification, advantages of denture labeling for the rapid identification during major disasters/accidents and the importance of maintaining the patient records.

    The paper, will present the most important non-invasive methods for diagnostic, in different fields of dentistry. Moreover, the laser-based methods will be emphasis. In orthodontics, 3D laser scanners are increasingly being used to establish database for normative population and cross-sectional growth changes but also to asses clinical outcomes in orthognatic surgical and non-surgical treatments. In prevention the main methods for diagnostic of demineralization and caries detection in early stages are represented by laser fluorescence - Quantitative Light Florescence (QLF); DiagnoDent-system-655nm; FOTI-Fiberoptic transillumination; DIFOTI-Digital Imaging Fiberoptic transillumination; and Optical Coherence Tomography (OCT). In odontology, Laser Doppler Flowmetry (LDF) is a noninvasive real time method used for determining the tooth vitality by monitoring the pulp microcirculation in traumatized teeth, fractured teeth, and teeth undergoing different conservative treatments. In periodontology, recently study shows the ability of LDF to evaluate the health of gingival tissue in periodontal tissue diseases but also after different periodontal treatments.

  16. Drugs for pain management in dentistry.

    Hargreaves, K; Abbott, P V

    2005-12-01

    Pain is one of the most common reasons patients seek dental treatment. It may be due to many different diseases/conditions or it may occur after treatment. Dentists must be able to diagnose the source of pain and have strategies for its management. The '3-D's' principle--diagnosis, dental treatment and drugs--should be used to manage pain. The first, and most important, step is to diagnose the condition causing the pain and identify what caused that condition. Appropriate dental treatment should then be undertaken to remove the cause of the condition as this usually provides rapid resolution of the symptoms. Drugs should only be used as an adjunct to the dental treatment. Most painful problems that require analgesics will be due to inflammation. Pain management drugs include non-narcotic analgesics (e.g., non-steroidal anti-inflammatory drugs, paracetamol, etc) or opioids (i.e., narcotics). Non-steroidal anti-inflammatory drugs (NSAIDs) provide excellent pain relief due to their anti-inflammatory and analgesic action. The most common NSAIDs are aspirin and ibuprofen. Paracetamol gives very effective analgesia but has little anti-inflammatory action. The opioids are powerful analgesics but have significant side effects and therefore they should be reserved for severe pain only. The most commonly-used opioid is codeine, usually in combination with paracetamol. Corticosteroids can also be used for managing inflammation but their use in dentistry is limited to a few very specific situations.

    This review is intended to provide the ceramic engineer with information about the history and current use of ceramics in dentistry, contemporary research topics, and potential research agenda. Background material includes intra-oral design considerations, descriptions of ceramic dental components, and the origin, composition, and microstructure of current dental ceramics. Attention is paid to efforts involving net-shape processing, machining as a forming method, and the analysis of clinical failure. A rationale is presented for the further development of all-ceramic restorative systems. Current research topics receiving attention include microstructure/processing/property relationships, clinical failure mechanisms and in vitro testing, wear damage and wear testing, surface treatments, and microstructural modifications. The status of the field is critically reviewed with an eye toward future work. Significant improvements seem possible in the clinical use of ceramics based on engineering solutions derived from the study of clinically failed restorations, on the incorporation of higher levels of "biomimicry" in new systems, and on the synergistic developments in dental cements and adhesive dentin bonding.

    Complementary and alternative medicine (CAM) represent a group of diverse medical and health care systems, practices, and products that are not considered to be part of conventional medicine. Biofeedback, acupuncture, herbal medication, massage, bioelectromagnetic therapy, meditation, and music therapy are examples of CAM treatments. Some dentists in the United States have used some of these treatments and products in their practices. Complementary medicines include herbal remedies, homeopathic medicines, and essential oils. There has been an increase in the use of herbal medicines in the US over the last 15-20 years. There is a public belief that these medicines are safe because they are made from natural sources. However, some of these products have associated adverse effects including toxicity and drug interactions. The health history taken by the dentist should include questions regarding the taking of herbal and over-the-counter medications. The dentist needs to be informed regarding the herbal and over-the-counter products that may impact the delivery of safe and effective dental treatment. In addition, the use of CAM treatments in dentistry should be based on evidence of effectiveness and safety as demonstrated in randomized clinical trials.

    The goal of interprofessional education (IPE) is to bring various professional groups together in the educational environment to promote collaborative practice and improve the health care of patients. Interest in IPE has been sparked by several factors in the health care system, including the increased awareness of oral-systemic connections, an aging population, the shift of the burden of illness from acute to chronic care, and lack of access to basic oral care. Increasingly, since the publication of the U.S. surgeon general's report in 2000, the dialogue surrounding IPE in dentistry has escalated. But how has dentistry changed regarding IPE since the report was released? This position paper argues that little has changed in the way dental students are taught and prepared to participate in IPE. The authors contend that academic dentistry and organized dentistry must take the lead in initiating and demanding IPE if dental students are to be prepared to work in the health care environment of the twenty-first century. Included are reasons why IPE is necessary and why dentistry must lead the conversation and participate in the solution to the oral health care crisis. It explores existing models and alternate approaches to IPE, barriers to implementation, and proposed strategies for academic institutions.

    Stanley Lithgow Drummond-Jackson was born in Northumberland and qualified from Edinburgh University Dental School in 1931. Even in the early stages of his practice he devoted his energies to the problem of pain control in dentistry, publishing his first paper in 1935. In the early 20th century most dental anaesthetics were inhalational with nitrous oxide, ether, ethyl chloride and chloroform. The introduction of intravenous hexobarbitone in 1931 led to bold and enthusiastic researchers like Drummond-Jackson to pioneer its use in dental practice. He published his major work on intravenous hexobarbitone in 1952. In 1957, Drummond-Jackson and a group of colleagues formed the now well-known organisation called 'Society for the Advancement of Anaesthesia in Dentistry' or SAAD. SAAD has grown from a group of 40 to over 4000 members worldwide. In 1969, the BMJ published an article condemning Drummond-Jackson's technique of intermittent intravenous methohexitone. At his personal expense, Drummond-Jackson brought a libel action against the BMJ and authors of this paper. There were no winners as the case was settled after 38 days and earned the reputation for being the longest and most expensive libel case in the history of the London Courts. Despite this setback the founder of SAAD devoted the last days of his life in research, teaching and abolishing fear and pain in dentistry. He gained international reputation as a teacher in dental anaesthesia and was honoured with fellowships and awards. He died in 1975 at the age of 66. In the early 1900s dental anaesthesia was only inhalational with mainly nitrous oxide on one hand and ether, ethyl chloride and chloroform on the other. Induction was at times stormy and prolonged and recovery was delayed. The synthesis of barbiturates, especially intravenous hexobarbitone (1931), thiopentone (1932) and methohexitone (1959) opened new avenues for dental anaesthesia. Modern anaesthesia owes a lot to early pioneers, many of them being

    Prevention reduces tooth loss, but little evidence supports biannual preventive care for all adults. We used risk-based approaches to test tooth loss association with 1 vs. 2 annual preventive visits in high-risk (HiR) and low-risk (LoR) patients. Insurance claims for 16 years for 5,117 adults were evaluated retrospectively for tooth extraction events. Patients were classified as HiR for progressive periodontitis if they had ≥ 1 of the risk factors (RFs) smoking, diabetes, interleukin-1 genotype; or as LoR if no RFs. LoR event rates were 13.8% and 16.4% for 2 or 1 annual preventive visits (absolute risk reduction, 2.6%; 95%CI, 0.5% to 5.8%; p = .092). HiR event rates were 16.9% and 22.1% for 2 and 1 preventive visits (absolute risk reduction, 5.2%; 95%CI, 1.8% to 8.4%; p = .002). Increasing RFs increased events (p < .001). Oral health care costs were not increased by any single RF, regardless of prevention frequency (p > .41), but multiple RFs increased costs vs. no (p < .001) or 1 RF (p = .001). For LoR individuals, the association between preventive dental visits and tooth loss was not significantly different whether the frequency was once or twice annually. A personalized medicine approach combining gene biomarkers with conventional risk factors to stratify populations may be useful in resource allocation for preventive dentistry (ClinicalTrials.gov, NCT01584479).

  3. Accuracy of near-surface aerosol extinction determined from columnar aerosol optical depth measurements in Reno, NV, USA

    NASA Astrophysics Data System (ADS)

    2014-10-01

    The aim of the present work is a detailed analysis of aerosol columnar optical depth as a tool to determine near-surface aerosol extinction in Reno, Nevada, USA, during the summer of 2012. Ground and columnar aerosol optical properties were obtained by use of in situ Photoacoustic and Integrated Nephelometer and Cimel CE-318 Sun photometer instruments, respectively. Both techniques showed that seasonal weather changes and fire plumes had enormous influence on local aerosol optics. The apparent optical height followed the shape but not magnitude of the development of the convective boundary layer when fire conditions were not present. Back trajectory analysis demonstrated that a local flow known as the Washoe Zephyr circulation often induced aerosol transport from Northern California over the Sierra Nevada Mountains that increased the aerosol optical depth at 500 nm during afternoons when compared with mornings. Aerosol fine mode fraction indicated that afternoon aerosols in June and July and fire plumes in August were dominated by submicron particles, suggesting upwind urban plume biogenically enhanced evolution toward substantial secondary aerosol formation. This fine particle optical depth was inferred to be beyond the surface, thereby complicating use of remote sensing measurements for near-ground aerosol extinction measurements. It is likely that coarse mode depletes fine mode aerosol near the surface by coagulation and condensation of precursor gases.

    Transcutaneous electric nerve stimulation (TENS) is a non-pharmacological method which is widely used by medical and paramedical professionals for the management of acute and chronic pain in a variety of conditions. Similarly, it can be utilized for the management of pain during various dental procedures as well as pain due to various conditions affecting maxillofacial region. This review aims to provide an insight into clinical research evidence available for the analgesic and non analgesic uses of TENS in pediatric as well as adult patients related to the field of dentistry. Also, an attempt is made to briefly discuss history of therapeutic electricity, mechanism of action of TENS, components of TENs equipment, types, techniques of administration, advantages and contradictions of TENS. With this we hope to raise awareness among dental fraternity regarding its dental applications thereby increasing its use in dentistry. Key words:Dentistry, pain, TENS. PMID:25674327

  6. InSAR analysis of the 2008 Reno-Mogul earthquake swarm: Evidence for incipient westward migration of Walker Lane style dextral faulting

    Analysis and modeling of InSAR data from small magnitude earthquakes can provide insights into the long-term evolution of the Basin and Range and Walker Lane. InSAR data covering the 2008 Reno-Mogul M 4.7 earthquake swarm indicate that the swarm was produced by slip on a newly recognized, northwest-striking dextral fault in the Reno basin. The earthquake is the smallest magnitude event modeled with InSAR to date in the seismically active western Basin and Range, and it provides new insights into regional neotectonic relations. The Reno basin is dominated by post-mid-Miocene, east-west extension near the boundary with the relatively stable Sierra Nevada and west of the northern Walker Lane, and the 2008 swarm occurred on the northern end of the Carson Range, a north-plunging extensional anticline. Although no surface rupture was associated with the swarm, 0.5-2.5 cm of radar line-of-sight change was detected by InSAR over a ~150 km2 area. We modeled six descending and six ascending InSAR pairs covering the swarm using the geodetic modeling program Geodmod. Inverse modeling of the InSAR data suggests that the swarm was generated by 25-75 cm of dextral displacement on a N44W-striking fault having a ~3 km rupture length and a rupture depth of ~2 km. As much as 4 cm of total across-fault dextral offset was detected. The InSAR results further indicated that a significant part of the ground deformation was post-seismic, in agreement with continuous GPS data (Blewitt et al., 2008). The model-derived moment magnitude Mw 5.3 was found to be larger than the instrumental Mw 5.1 indicating that a significant amount of the post-seismic slip was aseismic. The InSAR-detected strike-slip ground deformation is unique for the Reno basin which is in the extensional domain of the Sierra Nevada-Basin and Range Transition Zone. The modeling results support the concept that transcurrent faulting of the Walker Lane is migrating westward into areas previously affected only by extension, as

    2006-12-01

    Local anesthetics are the safest most effective drugs in medicine for the control and management of pain. They also represent the most important drugs in dentistry. Today, dentistry has a spectrum of local anesthetics that permit pain control to be tailored to the specific needs of the patient: short-, intermediate-, and long-acting drugs. Bupivacaine has become a standard part of the armamentarium for postsurgical pain control while articaine has become the second-most used local anesthetic in the United States since its introduction in 2000. Despite an increase in anecdotal reports of paresthesia since articaine's introduction there is yet, no supporting scientific evidence.

    As the use of information and communication technology (ICT) becomes more widespread in dentistry the risk of breaching electronic commerce laws and patient confidentiality increases. It is necessary to be aware of the responsibilities internet usage entails, especially within a dental practice where the protection of patient information is of the utmost importance. More should be done to outline the various precautions that should be taken to ensure ICT security within the professional domain, as it would appear dentistry has been neglected with regard to receiving the proper ICT education, training and support systems.

    The usage of ozone in dentistry has been proposed because of its antimicrobial, disinfectant, biocompatibility and healing properties. In the last decade a number of therapeutic protocols with ozone have been developed to address common dental infections associated with periodontal disease, RCT and caries. Despite these advantages, therapeutic ozone's application in dentistry is limited because of its possible side effects. Hence, dental practitioners need to know the proper usage of ozone therapy that can provide better patient care and considerably cut down the time and cost of the treatment.

    Infection prevention in dentistry is an important topic that has gained more interest in recent years and guidelines for the prevention of cross-transmission are common practice in many countries. However, little is known about the real risks of cross-transmission, specifically in the dental healthcare setting. This paper evaluated the literature to determine the risk of cross-transmission and infection of viruses and bacteria that are of particular relevance in the dental practice environment. Facts from the literature on HSV, VZV, HIV, Hepatitis B, C and D viruses, Mycobacterium spp., Pseudomonas spp., Legionella spp. and multi-resistant bacteria are presented. There is evidence that Hepatitis B virus is a real threat for cross-infection in dentistry. Data for the transmission of, and infection with, other viruses or bacteria in dental practice are scarce. However, a number of cases are probably not acknowledged by patients, healthcare workers and authorities. Furthermore, cross-transmission in dentistry is under-reported in the literature. For the above reasons, the real risks of cross-transmission are likely to be higher. There is therefore a need for prospective longitudinal research in this area, to determine the real risks of cross-infection in dentistry. This will assist the adoption of effective hygiene procedures in dental practice. PMID:22701774

    An update is provided of the literature on the role of odontology in human identification, based on a PubMed-Medline search of the last 5 years and using the terms: "forensic dentistry" (n = 464 articles), "forensic odontology" (n = 141 articles) and "forensic dentistry identification" (n = 169 articles). Apart from these initial 774 articles, others considered to be important and which were generated by a manual search and cited as references in review articles were also included. Forensic dentistry requires interdisciplinary knowledge, since the data obtained from the oral cavity can contribute to identify an individual or provide information needed in a legal process. Furthermore, the data obtained from the oral cavity can narrow the search range of an individual and play a key role in the victim identification process following mass disasters or catastrophes. This literature search covering the last 5 years describes the novelties referred to buccodental studies in comparative identification, buccodental evaluation in reconstructive identification, human bites as a method for identifying the aggressor, and the role of DNA in dental identification. The oral cavity is a rich and noninvasive source of DNA, and can be used to solve problems of a social, economic or legal nature.

    Background: Traditional Chinese acupuncture has a history of more than 2500 years and is one of the best-known complementary and alternative therapies. Acupuncture stimulates the nervous system and alters the processing and perception of pain signals and also releases natural painkillers, such as endorphins and serotonin in the nervous system. Acupuncture's successful use for various dental conditions has been proven. Thus, it is important for the dental clinicians to be familiar with the applications of acupuncture for dental disorders. Objective: One aim of this article is to review related articles in the literature that have focused on acupuncture and its applications in dentistry. Another aim is to provide a quick sketch of acupuncture use in dentistry for dental clinicians. Materials and Methods: A detailed search was performed to identify systematic reviews and research articles, using PUBMED and the Cochrane Database of Systematic Reviews. Language was restricted to English. Key search terms were acupuncture in dentistry, myofacial pain, temporomandibular disorders, xerostomia, dental pain and gag reflex. Results: All of the current the authors independently extracted data for analysis and review. Two independent reviewers screened the titles and abstracts of all the articles for eligibility. When the reviewers noted that an abstract or title of an article indicated that the article was potentially useful, full copies were retrieved. Ultimately, 40 articles underwent full-text review. Conclusions: The research to date certainly offers valid applications of acupuncture in dentistry. Meanwhile, practical strategies with the highest success rates are needed to use in further interventions.

    2012-07-01

    Stem cells can self-renew and produce different cell types, thus providing new strategies to regenerate missing tissues and treat diseases. In the field of dentistry, adult mesenchymal stem/stromal cells (MSCs) have been identified in several oral and maxillofacial tissues, which suggests that the oral tissues are a rich source of stem cells, and oral stem and mucosal cells are expected to provide an ideal source for genetically reprogrammed cells such as induced pluripotent stem (iPS) cells. Furthermore, oral tissues are expected to be not only a source but also a therapeutic target for stem cells, as stem cell and tissue engineering therapies in dentistry continue to attract increasing clinical interest. Part I of this review outlines various types of intra- and extra-oral tissue-derived stem cells with regard to clinical availability and applications in dentistry. Additionally, appropriate sources of stem cells for regenerative dentistry are discussed with regard to differentiation capacity, accessibility and possible immunomodulatory properties.

    1-[4-[2-(4-Bromobenzene-sulfonamino)ethyl]phenylsulfonyl]-3-(trans-4-methylcyclohexyl) urea (G004, CAS865483-06-3) is a synthetic sulfonylurea, incorporating the hypoglycemic active structure of glimepiride (CAS 93479-97-1) and anti-TXA2 receptor (TP) active structure of BM-531(CAS 284464-46-6). In this study, we evaluated the effect of G004 on hyperglycemia and dyslipidemia as well as diabetic nephropathy (DN) in db/db mice by gavage over 90 consecutive days of treatment. The fasting blood glucose (FBG), glucose, and insulin tolerance as well as dyslipidemia were effectively ameliorated in db/db mice treated with G004. Interestingly, renal histological results of db/db mice revealed that G004 markedly reversed the expansion of mesangial extracellular matrix (ECM), the early hallmark of DN. Indeed, G004 treatment downregulated the renal expressions of type 4 collagen (Col IV) and transforming growth factor-β1 (TGF-β1) in db/db mice. In addition, imbalance in expressions of matrix metalloproteinase-9 (MMP-9) and its tissue inhibitor-1 (TIMP-1) in db/db mice kidneys was observed. However, G004 increased and decreased the expressions of MMP-9 and TIMP-1, respectively. It is well known that TGF-β pathway signaling plays an essential role in hyperglycemia-induced cell protein synthesis. On the other hand, MMP/TIMP system is responsible for the breakdown and turnover of ECM. Thus, we speculate that G004 possibly attenuated ECM accumulation via remodeling the synthesis and degradation of ECM component Col IV through modulation in TGF-β1 and MMP-9/TIMP-1 expressions in kidneys of db/db mice. Results from this study provide a strong rationale for G004 to be an efficient glucose-controlling agent with significant reno-protective properties.

    After approximately 2 months of swarm-like earthquakes in the Mogul neighborhood of west Reno, NV, seismicity rates and event magnitudes increased over several days culminating in an Mw 4.9 dextral strike-slip earthquake on 26 April 2008. Although very shallow, the Mw 4.9 main shock had a different sense of slip than locally mapped dip-slip surface faults. We relocate 7549 earthquakes, calculate 1082 focal mechanisms, and statistically cluster the relocated earthquake catalog to understand the character and interaction of active structures throughout the Mogul, NV earthquake sequence. Rapid temporary instrument deployment provides high-resolution coverage of microseismicity, enabling a detailed analysis of swarm behavior and faulting geometry. Relocations reveal an internally clustered sequence in which foreshocks evolved on multiple structures surrounding the eventual main shock rupture. The relocated seismicity defines a fault-fracture mesh and detailed fault structure from approximately 2-6 km depth on the previously unknown Mogul fault that may be an evolving incipient strike-slip fault zone. The seismicity volume expands before the main shock, consistent with pore pressure diffusion, and the aftershock volume is much larger than is typical for an Mw 4.9 earthquake. We group events into clusters using space-time-magnitude nearest-neighbor distances between events and develop a cluster criterion through randomization of the relocated catalog. Identified clusters are largely main shock-aftershock sequences, without evidence for migration, occurring within the diffuse background seismicity. The migration rate of the largest foreshock cluster and simultaneous background events is consistent with it having triggered, or having been triggered by, an aseismic slip event.

    Background Consensus guidelines are useful to improve clinical decision making. Therefore, the methodological evaluation of these guidelines is of paramount importance. Low quality information may guide to inadequate or harmful clinical decisions. Objective To evaluate the methodological quality of consensus guidelines published in implant dentistry using a validated methodological instrument. Methods The six implant dentistry journals with impact factors were scrutinised for consensus guidelines related to implant dentistry. Two assessors independently selected consensus guidelines, and four assessors independently evaluated their methodological quality using the Appraisal of Guidelines for Research & Evaluation (AGREE) II instrument. Disagreements in the selection and evaluation of guidelines were resolved by consensus. First, the consensus guidelines were analysed alone. Then, systematic reviews conducted to support the guidelines were included in the analysis. Non-parametric statistics for dependent variables (Wilcoxon signed rank test) was used to compare both groups. Results Of 258 initially retrieved articles, 27 consensus guidelines were selected. Median scores in four domains (applicability, rigour of development, stakeholder involvement, and editorial independence), expressed as percentages of maximum possible domain scores, were below 50% (median, 26%, 30.70%, 41.70%, and 41.70%, respectively). The consensus guidelines and consensus guidelines + systematic reviews data sets could be compared for 19 guidelines, and the results showed significant improvements in all domain scores (p < 0.05). Conclusions Methodological improvement of consensus guidelines published in major implant dentistry journals is needed. The findings of the present study may help researchers to better develop consensus guidelines in implant dentistry, which will improve the quality and trust of information needed to make proper clinical decisions.

    BackgroundThis systematic appraisal was conducted to determine if the Evidence-Based Dentistry Journal (EBDJ) acts as a reliable and contemporary source of knowledge for practitioners across all disciplines within dentistry.ObjectivesThe main objectives were to determine i) the year the articles were published and included in the EBDJ; ii) if the articles published covered all fields equally within dentistry; iii) the type of study design of the articles reported in the journal and; iv) the level of expertise of the writers of the commentaries.MethodsThis study used a systematic approach to assess the articles included in the journal. Data were extracted on the difference in the year the article was originally published and the year the article was included in the EBDJ, the number of articles in each dental discipline, the type of study designs included in the journal and the expertise of the commentators of each article. The information provided by the journal was validated by accessing the original articles through electronic databases.ResultsThe appraisal considered the 582 articles that met the inclusion criteria. Overall, 45.3% of the articles were included in the EBDJ in the same year and 44.8% of the articles were included a year after they were originally published. The number of articles varied across disciplines within dentistry: 23.7% from dental public health, 18.4% from periodontology and 11.8% from orthodontics, with only 4.6% from prosthodontics, 1% from oral pathology and 0.5% from dental materials. Most of the articles were systematic reviews and randomised controlled trials at 72% and 22.3% respectively. The writers of the commentaries were mostly academics and hospital consultants (71.2% and 13.6% commentators).ConclusionsOn the whole, it can be concluded that the journal acts as a reliable and contemporary source of knowledge/evidence for dentists, however, not all specialities within dentistry had equal coverage.

    Cloud-to-ground (CG) lightning flashes recorded by both the National Lightning Detection Network (NLDN) and Earth Networks Total Lightning Network (ENTLN) are compared with three-dimensional lightning mapping observations from the Oklahoma Lightning Mapping Array (OKLMA) and storm chaser video recorded of the 31 May 2013 El Reno tornadic supercell. The El Reno Survey Project (El-Reno-Survey.net) was created to crowd-source the abundance of storm chaser video from this event and provide open-access to the scientific community of the data. An initial comparison of CG lightning flashes captured on these videos with CG data from NLDN revealed a disagreement on the total number of flashes, with NLDN recording many negative CG flashes at lower peak amplitude not apparent in any of the videos. For this study, the area of the comparison was expanded to include the entire storm and data from both the ENTLN and LMA were added to compare the observations from each network in terms of timestamp, location detection, peak current, and polarity of each flash in the period 2230-2330 UTC. An initial comparison of 557 matched NLDN and ENLTN CG flashes, indicated predominately negative polairy CG flashes (58% NLDN/77% ENI) throughout the storm during this period. However, after a 15 kA peak current filter was applied, the NLDN indicated primarily positive polarity (84% +CG) while ENTLN still indicated primarily negative polarity (77% -CG) for the 264 remaining matched flashes. Before the filter was applied, the average distance between the two networks for the same flash was more than 2 km, but improved to approximately 1 km after the 15 kA filter was applied, likely removing some misidentified cloud flashes of uncertain location. This misclassification of IC flashes as CG at low peak current amplitudes for both networks is further evident when compared to video and the OKLMA data. Additionally, the charge analysis of OKLMA flashes revealed the NLDN-determined positive-polarity as

    This paper describes how a relatively new style of online learning, a massive open online course (MOOC), may be used to raise aspirations and widen participation in dental professions. A MOOC was designed and run with the aim of engaging prospective students of dental professions in learning and discussion. Over 4,200 learners signed up, and 450 students fully completed this first run of the course. The course attracted a significantly younger demographic than is typical for MOOCs, and nearly a third who responded to the pre-course survey reported they were doing the course specifically as preparation for a dental degree. The approach also provided a platform for public engagement on the subject of dentistry with participants, both dental professionals and members of the public, contributing to discussion around the learning materials from around the world, providing a unique, internationalised perspective of oral healthcare for learners. This study shows that there is genuine potential for MOOCs to involve people from disadvantaged backgrounds in higher education by offering free, accessible, enjoyable and engaging educational experiences. The data gives us cautious optimism that these courses can play a significant role within a platform of other WP interventions.

    2015-12-01

    Recorded by numerous local and temporary stations and containing over 5000 earthquakes shallower than 5-km depth, the 2008 Mogul Earthquake sequence (MES) in west Reno, NV provides an excellent dataset for investigating earthquake interaction and physical properties of a long-duration earthquake swarm. The MES was energetic for a 6-month period beginning in late Feb 2008 with 8 weeks of foreshock activity leading to the Mw 5.0 mainshock on Apr 26, 2008. We develop a high-precision catalog with relative hypocentral errors less than 100 meters using the double-difference algorithm HypoDD (Waldhauser and Ellsworth, 2000). The data is objectively decomposed into spatiotemporal subclusters by applying the statistical declustering methods of Zaliapin et al. (2008) based on nearest-neighbor space-time-magnitude distances. We choose a cluster threshold using a Gaussian mixture model. This approach results in 57 distinct subclusters, with a minimum of 5 earthquakes each, that together comprise 66% of the entire MES relocated catalog. Ten of the 57 subclusters have mainshocks that occur prior to the Mw 5.0 mainshock. All single events or those clustered with less than 4 other events are ignored in further analysis. We compare the spatial and temporal patterns, including aftershock decay and/or diffusion rates, of each subcluster as well as Poisson's ratio, focal mechanisms, and source parameters for each. Over 1000 focal mechanisms developed using the HASH algorithm of Hardebeck and Shearer (2002) reveal distinct right-lateral, left-lateral, normal, and normal-oblique structures, which the declustering method identifies successfully. Stress drops for 90 events greater than or equal to Ml 2.5 are estimated from multiple EGF spectral ratios of P- and S-waves, objectively chosen based on signal-to-noise ratio, cross-correlation, bandwidth, and corner-frequency variance. We also investigate how the subclusters interact with and overlap each other in time and space to understand

    2016-01-01

    The GMA committee for dentistry of the German Society for Medical Education (GMA) considers its’ main purpose the representation and interconnection of all aspects of dentistry with and within the GMA. Teaching and assessing practical skills during training is traditionally of great importance in dental education. This is also reflected in the National Competence Based Catalogue of Learning Objectives for Dental Education (NKLZ). Practical skills are not comprised in a separate chapter as they are in the National Competence Based Catalogue of Learning Objectives for Medical Education (NKLM), but are considered in all sections of the NKLZ for the purpose of interdisciplinary patient- or disease-specific application, targeting the educational level of acting competency. The implementation of the associated joined interdisciplinary integrated educational concept has undoubtedly been a challenge for dental curriculum development against the backdrop of German Dental Licensure Act dating back to 1955.

    Teeth are the most natural, noninvasive source of stem cells. Dental stem cells, which are easy, convenient, and affordable to collect, hold promise for a range of very potential therapeutic applications. We have reviewed the ever-growing literature on dental stem cells archived in Medline using the following key words: Regenerative dentistry, dental stem cells, dental stem cells banking, and stem cells from human exfoliated deciduous teeth. Relevant articles covering topics related to dental stem cells were shortlisted and the facts are compiled. The objective of this review article is to discuss the history of stem cells, different stem cells relevant for dentistry, their isolation approaches, collection, and preservation of dental stem cells along with the current status of dental and medical applications.

    In dental practice there is an increasing need for predictable therapeutic protocols able to regenerate tissues that, due to inflammatory or traumatic events, may suffer from loss of their function. One of the topics arising major interest in the research applied to regenerative medicine is represented by tissue engineering and, in particular, by stem cells. The study of stem cells in dentistry over the years has shown an exponential increase in literature. Adult mesenchymal stem cells have recently been isolated and characterized from tooth-related tissues and they might represent, in the near future, a new gold standard in the regeneration of all oral tissues. The aim of our review is to provide an overview on the topic reporting the current knowledge for each class of dental stem cells and to identify their potential clinical applications as therapeutic tool in various branches of dentistry.

    The horizons of treatment options in dentistry are broadening rapidly. In this scenario, applications of unconventional treatment options like use of botulinum toxin (BT) are gaining momentum. The use of BT has been popularly accepted in esthetic procedures like management of facial wrinkles; however, it has been documented to be successful in a variety of conditions. Of particular interest to this paper are applications of BT in the maxillofacial region, concerned to dentistry. BT offers a transient, reversible, relatively safe treatment option to many conditions of interest to a dental practitioner. Dental surgeons by their virtue of being extensively aware of the anatomy of faciomaxillary region are a potential pool of operators who can use BT in their armamentarium with minor skill enhancement and thus widen the perspective of alternative, minimally invasive options to refractory conditions or invasive protocols.

    Dentistry-related applications for mobile phones are becoming a popular way of accessing information for students, practitioners and patients. The aim of this article is to review the use of mobile technology, such as 'apps', within dentistry. Over time, there has been a change from desktop learning (D-learning) to mobile learning (M-learning) and this has only been possible with the aid of electronic media and the growth of the Internet. In spite of the increase in mobile applications, there is a need for any information to have a strong underlying evidence base. Several good examples of dental applications which take full advantage of this electronic medium are available. However, developers of mobile applications should provide good quality, peer-reviewed evidence to validate their material.

  19. Can Dentistry Have Two Contracts with the Public?

    2015-01-01

    The social contract is an implicit agreement between parts of society and society as a whole. Since the Middle Ages, the learned professions, recently including dentistry, have had a covenantal relationship with the public based on trust, exchanging monopoly privileges for benefiting the public good. Unlike commercial trade in commodities, professional relationships are grounded in ensuring an adequate level of oral health to all. A second contract is emerging where dentists relate to society as business operators, exchanging commodity services for a price. Recent actions by the Federal Trade Commission and the U.S. Supreme Court make it unlikely that dentistry will be able to enjoy only selected aspects of each contract while avoiding obligations that it finds unfavorable.

    This article aims to provide a brief background to the current applications of finite-element analysis (FEA) in nanomedicine and dentistry. FEA was introduced in orthopedic biomechanics in the 1970s in order to assess the stresses and deformation in human bones during functional loadings and in the design and analysis of implants. Since then, it has been applied with great frequency in orthopedics and dentistry in order to analyze issues such as implant design, bone remodeling and fracture healing, the mechanical properties of biomedical coatings on implants and the interactions at the bone-implant interface. More recently, FEA has been used in nanomedicine to study the mechanics of a single cell and to gain fundamental insights into how the particulate nature of blood influences nanoparticle delivery.

    The notion of utilizing laser technology in conservative dentistry was proposed in 1990 by Hibst and Keller, who introduced the possibility of using an Er:YAG laser as alternative to conventional instruments such as the turbine and micro-motor. In subsequent years a continuing effort has been made by clinicians, researchers and commercial companies to improve the technology. The aim of this clinical study is to demonstrate, by the description of different clinical cases, the possibilities and the advantages of using Er:YAG lasers in conservative dentistry and to show that better results may be achieved in terms of stronger adhesion, less invasiveness, reduced pain as well as greater comfort and satisfaction of patients.

    Abstract Background: Traditional Chinese acupuncture has a history of more than 2500 years and is one of the best-known complementary and alternative therapies. Acupuncture stimulates the nervous system and alters the processing and perception of pain signals and also releases natural painkillers, such as endorphins and serotonin in the nervous system. Acupuncture's successful use for various dental conditions has been proven. Thus, it is important for the dental clinicians to be familiar with the applications of acupuncture for dental disorders. Objective: One aim of this article is to review related articles in the literature that have focused on acupuncture and its applications in dentistry. Another aim is to provide a quick sketch of acupuncture use in dentistry for dental clinicians. Materials and Methods: A detailed search was performed to identify systematic reviews and research articles, using PUBMED and the Cochrane Database of Systematic Reviews. Language was restricted to English. Key search terms were acupuncture in dentistry, myofacial pain, temporomandibular disorders, xerostomia, dental pain and gag reflex. Results: All of the current the authors independently extracted data for analysis and review. Two independent reviewers screened the titles and abstracts of all the articles for eligibility. When the reviewers noted that an abstract or title of an article indicated that the article was potentially useful, full copies were retrieved. Ultimately, 40 articles underwent full-text review. Conclusions: The research to date certainly offers valid applications of acupuncture in dentistry. Meanwhile, practical strategies with the highest success rates are needed to use in further interventions. PMID:25538815

  5. Enduring symbols of dentistry: international metaphors of dental science.

    Pearn, J

    2008-12-13

    Dentists' contributions to science and society extend beyond the practice of clinical dentistry and preventive oral health. Such service encompasses contributions to biology specifically and more generally to societal good works for which dentists are particularly esteemed. The profession of dentistry promotes the history and heritage of its craft and those who practise it. Enduring symbols of dentistry take many forms. These include metonymic emblems such as those of Cadmus and Saint Apollonia and the portrayal of effigies of twentieth century dentists on eponymous medals. Other enduring symbols are to be found in the names of streets and towns (eg Normanville in Australia) which commemorate dentists; and in the worldwide scientific names of plants and animal species which perpetuate singular contributions of dentists to biological science. Such include the scientific names of grasses (Deyeuxia rodwayi) after the Tasmanian dentist, Dr Leonard Rodway (1853-1936); seaweeds (Jeannerettia sp.) after a seaweed of the Pacific and Southern Oceans, after Dr Henry Jeannerett (1802-1886); gastropods (Typhina yatesi) after Dr Lorenzo Yates (1837-1909); copepods (eg Mimocalanus heronae) named to commemorate the life and works of Gayle Ann Heron (b.1923), a dental hygienist of the University of Washington, USA; and crabs (eg Cancer bellianus) named to commemorate the life and works of the leading British dentist of his day, Thomas Bell (1792-1880). This paper explores this theme of the creation and promotion of enduring symbols of dental science - enshrined in the civic, numismatic and taxonomic record.

    As I noted earlier, all things being equal, patients prefer tooth-colored restorations. This technique has removed virtually all the barriers to treatment and makes things a lot more equal. There's the cost factor (Dramatically reduced!) There's the fear-of-needle factor (Gone!) There's the time factor (Minimized!). In fact, prepping and placing these occlusal veneers is so fast I can now do 8 to 10 amalgam rehabs in one appointment. Doing so many in a short time is extremely profitable, even at the reduced fee. This technique certainly does not qualify as "great dentistry," but it brings "desire-motivated" cosmetic dentistry to an entirely new universe and those patients are appreciative. They're even referring their friends! In my practice, veneering amalgam has brought cosmetic dentistry to many patients who would never agree to have their restorations replaced with traditional composite resin. And it has brought me several additional thousand dollars in collections each month. So this is a classic "win-win" situation. Patients are getting cosmetic restorations they didn't think they could afford, and I'm making a great profit doing it.

    2009-01-01

    While widespread advances in tissue engineering have occurred over the past decade, many challenges remain in the context of tissue engineering and regeneration of the tooth. For example, although tooth development is the result of repeated temporal and spatial interactions between cells of ectoderm and mesoderm origin, most current tooth engineering systems cannot recreate such developmental processes. In this regard, microscale approaches that spatially pattern and support the development of different cell types in close proximity can be used to regulate the cellular microenvironment and, as such, are promising approaches for tooth development. Microscale technologies also present alternatives to conventional tissue engineering approaches in terms of scaffolds and the ability to direct stem cells. Furthermore, microscale techniques can be used to miniaturize many in vitro techniques and to facilitate high-throughput experimentation. In this review, we discuss the emerging microscale technologies for the in vitro evaluation of dental cells, dental tissue engineering, and tooth regeneration.

    Laser-doppler flowmetry (LDF) is a diagnostic method for checking and judging vitality in tissues. In dentistry, with the help of LDF, there can be investigated short-term or long-term changes of the oral microcirculation. Defects in the LDF equipment which go undiscovered lead to changes in the quality of the biosignals and hamper diagnosis. Reliable and reproducible results are only obtained if the LDF equipment concerned there exists a standardized quality assurance program. There has been developed and tested a method for constancy checks in LDF measurements. The investigation shows that before each clinical application of an LDF equipment careful testing is necessary.

  19. Occupational blood exposures in dentistry: a decade in review.

    PubMed

    Cleveland, J L; Gooch, B F; Lockwood, S A

    1997-10-01

    This review summarizes data from self-reported and observational studies describing the nature, frequency, and circumstances of occupational blood exposures among US dental workers between 1986 and 1995. These studies suggest that, among US dentists, percutaneous injuries have declined steadily over the 10-year period. Data also suggest that, in 1995, most dental workers (dentists, hygienists assistants, and oral surgeons) experienced approximately three injuries per year. Work practices (eg, using an instrument instead of fingers to retract tissue), safer instrumentation or design (eg, self-sheathing needles, changes in dental-unit design), and continued worker education may reduce occupational blood exposures in dentistry further.

    Prion diseases are a group of fatal neurodegenerative diseases that are rapidly progressive and fatal, with no definite cure. There are no reported cases of prion disease transmission arising from dental procedures. Nevertheless, there is a theoretical but real risk of transmission of prion disease from dental instruments. A review was made of studies up to 2008 to provide an update of the characteristics, risk of transmission, and the infection-control implications of prions in the field of dentistry. As the prions are resistant to conventional sterilization methods, highly-specific, cross-infection control measures are required when managing patients infected with these.

    To assess the effect of aqueous extract of Carum carvi seeds in experimentally induced diabetic nephropathy (DN) in rodents, we studied 48 adult male Wistar rats divided into 4 groups: normal controls (group A), diabetes positive control (group B), and experimental (groups C and D). They received Carum carvi extract as a renoprotective agent. Rats having fasting blood glucose levels over 280 mg/dL were included in this study. Group C rats received STZ (60 mg/kg) and aqueous extract of Carum carvi at 30 mg/kg of body weights. On the other hand group D rats received STZ (60 mg/kg) and aqueous extract of Carum carvi at 60 mg/kg of body weight. Blood samples were collected on the 60 th day, and kidneys were also extracted for examination. The diabetic group rats showed a variable increase in the serum levels of glucose, urea, creatinine, total urinary protein and microalbuminuric levels. Body weight decreased and urine volume increased in the diabetic groups. 30 mg/kg body weight of Carum carvi dose decreased the levels of these parameters in rats. On the other hand, 60 mg/kg body weight of Carum carvi dose significantly decreased the levels of the biochemical parameters. The morphological examination of group C rats showed no changes whereas the rats in group D showed moderate changes. Carum carvi constituents, especially flavonoids and carvone have strong anti-oxidant activity, which provides reno-protection against diabetes and its complications. In conclusion, high dose of Carum carvi aqueous seeds extract (60 mg/kg) showed reno-protection against STZ induced dia-betic nephropathy in rats.

    2010-01-01

    Geriatric dentistry and its instruction are critical in a rapidly aging population. Japan is the world’s fastest-aging society, and thus geriatric dentistry education in Japan can serve as a global model for other countries that will soon encounter the issues that Japan has already confronted. This study aimed to evaluate geriatric dental education with respect to the overall dental education system, undergraduate geriatric dentistry curricula, mandatory internships, and graduate geriatric education of a selected dental school in Japan. Bibliographic data and local information were collected. Descriptive and statistical analyses (Fisher and Chi-square test) were conducted. Japanese dental schools teach geriatric dentistry in 10 geriatric dentistry departments as well as in prosthodontic departments. There was no significant differences found between the number of public and private dental schools with geriatric dentistry departments (p = 0.615). At Showa University School of Dentistry, there are more didactic hours than practical training hours; however, there is no significant didactic/practical hour distribution difference between the overall dental curriculum and fourth-year dental students’ geriatric dental education curriculum (p=0.077). Graduate geriatric education is unique because it is a four-year Ph.D. course of study; there is neither a Master’s degree program nor a certificate program in Geriatric Dentistry. Overall, both undergraduate and graduate geriatric dentistry curricula are multidisciplinary. This study contributes to a better understanding of geriatric dental education in Japan; the implications of this study include developing a clinical/didactic curriculum, designing new national/international dental public health policies, and calibrating the competency of dentists in geriatric dentistry.

    During dental education, dental students learn how to examine patients, make diagnosis, plan treatment and perform dental procedures perfectly and efficiently. However, progresses in computer-based technologies including virtual reality (VR) simulators, augmented reality (AR) and computer aided design/computer aided manufacturing (CAD/CAM) systems have resulted in new modalities for instruction and practice of dentistry. Virtual reality dental simulators enable repeated, objective and assessable practice in various controlled situations. Superimposition of three-dimensional (3D) virtual images on actual images in AR allows surgeons to simultaneously visualize the surgical site and superimpose informative 3D images of invisible regions on the surgical site to serve as a guide. The use of CAD/CAM systems for designing and manufacturing of dental appliances and prostheses has been well established. This article reviews computer-based technologies, their application in dentistry and their potentials and limitations in promoting dental education, training and practice. Practitioners will be able to choose from a broader spectrum of options in their field of practice by becoming familiar with new modalities of training and practice. PMID:28392819

    Laser technology has been recently introduced into the dental field with the idea to replace drilling. Having a less painful first dental experience by the use of modern instruments like laser can be an efficient preventive and therapeutic strategy in pediatric dentistry. Pedodontists need to learn the new less invasive technologies and adopt them in their routine practice. This study aimed to review the available types of lasers and their applications in pediatric dentistry. An electronic search was carried out in IranMedex, InterScience, Scopus, Science Direct, PubMed, ProQuest, Medline and Google Scholar databases to find relevant articles published from 2000 to 2014. Relevant textbooks were reviewed as well. Laser can be used as a suitable alternative to many conventional diagnostic and therapeutic dental procedures. It is especially efficient for caries detection and removal, pulp therapy, lowering the risk of infection, inflammation and swelling and reducing bleeding. On the other hand, due to minimal invasion, laser treatment is well tolerated by children. Improved patient cooperation leads to higher satisfaction of the parents, dentists and the children themselves.

The characteristics and expectations of Generation X faculty are explored: who are they and what do they want from the academic workplace? The article describes the culture clash that often occurs when Gen Xers encounter policies and practices that were designed by and for prior generations (e.g., Traditionalists and Boomers) who filled the ranks of dental school faculty in the 1970s, 1980s, and 1990s. Recommendations for rethinking academic employment systems in ways that might make the university workplace more attractive to Generation X are described.

  14. Laser sources in dentistry and radiation safety regulations

    NASA Astrophysics Data System (ADS)

    De Luca, D.; Gaeta, G. M.; Lepore, M.

    2007-02-01

    Nowadays laser sources are largely adopted in dentistry due to their unique properties making them good candidates to substitute traditional scalpel and conventional diamond bur in the surgery of the soft and hard oral tissue, respectively. The large use of laser sources outside the research laboratories without the need of highly specialized personnel can ask for a widespread knowledge of safety issues related to this kind of equipment. The main hazard of accidental exposures regards eyes injury but increasing the power of the laser beam also skin can be involved. Safety legislations in Europe and U.S.A. take into account non ionizing radiations and laser radiation for the hazards for the health deriving from physical agents. Laser safety standards introduce 3 useful parameters for hazard characterization: "Accessible Emission Limit" (AEL), "Maximum Permissible Exposure" (MPE) and "Nominal Ocular Hazard Distance" (NOHD). We measured the MPE and NOHD for Er:YAG and other laser sources currently adopted in dentistry and we compared our results with data elaborated from standards in order to single out safe and comfortable working conditions. In fact an experimental assessment of the hazard parameters and the comparison with those of reference from safety standards turns out to be useful in order to estimate the residual hazard that can be still present after applying all the engineering protection and administrative rules.

  15. Persuasive evidence that formocresol use in pediatric dentistry is safe.

    PubMed

    Milnes, Alan R

    2006-04-01

    Concern has been expressed about the safety of formocresol use in pediatric dentistry. Formaldehyde, a primary component in formocresol, is a hazardous substance and is considered a probable human carcinogen by Health Canada. However, humans inhale and ingest formaldehyde daily and also produce this compound as part of normal cellular metabolism. The human body is physiologically equipped to handle this exposure through multiple pathways for oxidation of formaldehyde to formate and incorporation into biological macromolecules via tetrahydrofolate-dependent one-carbon biosynthetic pathways. Recent re-evaluation of earlier research that examined potential health risks associated with formaldehyde exposure has shown that the research was based on flawed assumptions, which resulted in erroneous conclusions. This review examines more recent research about formaldehyde metabolism, pharmacokinetics and carcinogenicity, the results of which indicate that formaldehyde is probably not a potent human carcinogen under conditions of low exposure. Extrapolation of these research results to pediatric dentistry suggests an inconsequential risk of carcinogenesis associated with formaldehyde use in pediatric pulp therapy. Areas for further investigation are suggested.

    2008-10-01

    Infectious endocarditis is a cardiac pathology of bacterial, viral or more rarely mycotic origin developing on the surfaces of the endocardium or heart valves. Predisposing conditions are congenital malformations of the heart or valvular acquired alterations, as well as the presence of a valvular prosthesis. The microorganisms involved in the etiology and pathogenesis of the damage of such infection (bacterias, viruses or yeasts) determine the formation of the endocardic vegetations typical of this condition. Such lesions can be located on the valvular or the parietal endocardium and sometimes on the endothelium of a great artery. In despite of the elevated standards of instrumental investigations and therapeutic protocols, the bacterial endocarditis represents a pathology of wide interest, scientific and social, due to its high rate of incidence, morbility and mortality. Still now infectious endocarditis causes death in 20-30% of the patients. Although the significant progress on prevention of the infectious diseases and of the cross infections in dentistry practice, from the tartar ablation up to the oncologic oral surgery, still now the skills of oral hygiene and dentistry represent a potential threat for the development of an infectious endocarditis in predisposed patients. The authors, on the base of the revision of the literature and of their own clinical experience, show the etiology, pathophysiology and the clinical pictures related to such complex disease.

    2017-02-01

    Additive manufacturing or 3D printing is becoming an alternative to subtractive manufacturing or milling in the area of computer-aided manufacturing. Research on material for use in additive manufacturing is ongoing, and a wide variety of materials are being used or developed for use in dentistry. Some materials, however, such as cobalt chromium, still lack sufficient research to allow definite conclusions about the suitability of their use in clinical dental practice. Despite this, due to the wide variety of machines that use additive manufacturing, there is much more flexibility in the build material and geometry when building structures compared with subtractive manufacturing. Overall additive manufacturing produces little material waste and is energy efficient when compared to subtractive manufacturing, due to passivity and the additive layering nature of the build process. Such features make the technique suitable to be used with fabricating structures out of hard to handle materials such as cobalt chromium. The main limitations of this technology include the appearance of steps due to layering of material and difficulty in fabricating certain material generally used in dentistry for use in 3D printing such as ceramics. The current pace of technological development, however, promises exciting possibilities.

  19. The application of silicon and silicates in dentistry: a review.

    PubMed

    Lührs, A-K; Geurtsen, Werner

    2009-01-01

    Silicates and silicate-based compounds are frequently used materials in dentistry. One of their major applications is their use as fillers in different dental filling materials such as glass-ionomer cements, compomers, composites, and adhesive systems. In these materials, the fillers react with acids during the setting process or they improve the mechanical properties by increasing physical resistance, thermal expansion coefficient and radiopacity in acrylic filling materials. They also reduce polymerization shrinkage, and increase esthetics as well as handling properties. Furthermore, silicates are used for the tribochemical silication of different surfaces such as ceramics or alloys. The silicate layer formed in this process is the chemical basis for silanes that form a bond between this layer and the organic composite matrix. It also provides a micromechanical bond between the surface of the material and the composite matrix. Silicates are also a component of dental ceramics, which are frequently used in dentistry, for instance for veneers, inlays, and onlays, for denture teeth, and for full-ceramic crowns or as crown veneering materials.

    Objective: Between a quarter and a third of adults with intellectual disability is estimated to have dental anxiety. Unpleasant stimuli, such as the injection of local anaesthesia or the noise and vibration of rotary instruments, may provoke anxiety and subsequent low compliance until the opposition to the treatment. The use of Er:YAG laser in conservative dentistry had a great development in these last years thank to new devices and also to their advantages when compared to the conventional instruments. The aim of this clinical study was to show the advantages of the Er:YAG laser in the conservative treatment of Special Care patients. Methods: Four cases are here described to show the Er:YAG laser use in our Unit on special needs patients. Results and conclusions: Based on the experience gained on conservative laser-assisted treatments performed in a time of 5 years at our Dentistry, Special Needs and Maxillo-Facial Surgery Unit we may affirm that Er:YAG laser may be considered as a good way to improve the cooperation, to reduce anxiety related to rotating instruments and to reach better results with equal or shorter operating times.

    This study describes what training programs in pediatric dentistry and dental anesthesiology are doing to meet future needs for deep sedation/general anesthesia services required for pediatric dentistry. Residency directors from 10 dental anesthesiology training programs in North America and 79 directors from pediatric dentistry training programs in North America were asked to answer an 18-item and 22-item online survey, respectively, through an online survey tool. The response rate for the 10 anesthesiology training program directors was 9 of 10 or 90%. The response rate for the 79 pediatric dentistry training program directors was 46 of 79 or 58%. Thirty-seven percent of pediatric dentistry programs use clinic-based deep sedation/general anesthesia for dental treatment in addition to hospital-based deep sedation/general anesthesia. Eighty-eight percent of those programs use dentist anesthesiologists for administration of deep sedation/general anesthesia in a clinic-based setting. Pediatric dentistry residency directors perceive a future change in the need for deep sedation/general anesthesia services provided by dentist anesthesiologists to pediatric dentists: 64% anticipate an increase in need for dentist anesthesiologist services, while 36% anticipate no change. Dental anesthesiology directors compared to 2, 5, and 10 years ago have seen an increase in the requests for dentist anesthesiologist services by pediatric dentists reported by 56% of respondents (past 2 years), 63% of respondents (past 5 years), and 88% of respondents (past 10 years), respectively. Predicting the future need of dentist anesthesiologists is an uncertain task, but these results show pediatric dentistry directors and dental anesthesiology directors are considering the need, and they recognize a trend of increased need for dentist anesthesiologist services over the past decade.

Dental anesthesiology directors compared to 2, 5, and 10 years ago have seen an increase in the requests for dentist anesthesiologist services by pediatric dentists reported by 56% of respondents (past 2 years), 63% of respondents (past 5 years), and 88% of respondents (past 10 years), respectively. Predicting the future need of dentist anesthesiologists is an uncertain task, but these results show pediatric dentistry directors and dental anesthesiology directors are considering the need, and they recognize a trend of increased need for dentist anesthesiologist services over the past decade.

    A chief means of print advertising in the Victorian era was the "trade card." Innumerable products, companies, and services were highlighted on colorful chromolithographic trade cards, and these became desirable collectible objects which were pasted into scrapbooks and enjoyed by many families. Dentistry- and oral health-related subjects were often depicted on Victorian trade cards, and esthetic and restorative dentistry themes were featured. This review describes the history of advertising trade cards and offers a photographic gallery of dentistry-related cards of the era.

    As in many other industries, production stages are increasingly becoming automated in dental technology. As the price of dental laboratory work has become a major factor in treatment planning and therapy, automation could enable more competitive production in high-wage areas like Western Europe and the USA. Advances in computer technology now enable cost-effective production of individual pieces. Dental restorations produced with computer assistance have become more common in recent years. Most dental companies have access to CAD/CAM procedures, either in the dental practice, the dental laboratory or in the form of production centres. The many benefits associated with CAD/CAM generated dental restorations include: the access to new, almost defect-free, industrially prefabricated and controlled materials; an increase in quality and reproducibility and also data storage commensurate with a standardised chain of production; an improvement in precision and planning, as well as an increase in efficiency. As a result of continual developments in computer hardware and software, new methods of production and new treatment concepts are to be expected, which will enable an additional reduction in costs. Dentists, who will be confronted with these techniques in the future, require certain basic knowledge if they are to benefit from these new procedures. This article gives an overview of CAD/CAM-technologies and systems available for dentistry today.

    2010-01-01

    This paper combines resources from the organization studies and sociology literatures to advance understanding of institutional change processes in healthcare that emerge from the professionalization projects of occupations. Conceptually, we introduce a model that combines the ‘archetype’ approach to analyzing structural change with a framework for analyzing the agency of emergent professions. We then employ the model to frame a historical case analysis (1972-2009) of the highly contested process by which the occupation of dental hygiene in the US fought to introduce a new organizational form, the alternative practice hygiene (APH) archetype. This archetype challenges the traditional model (the Dentist's Office archetype) that is supported by the dominant dentistry profession. Our analysis contributes two main sets of empirical findings. First, we present a systematic comparison of the APH and Dentist's Office archetypes in terms of their belief systems, formal structures, agents, and policy implications (e.g., access to services). Second, we provide an account of the agency of dental hygienists' attempts to secure the APH model as part of their professionalization project. PMID:21075497

    The curricula of dental faculties in many countries of the European Union can be described as odontological. The faculties of some of the countries who have become and are becoming members of the European Community have traditionally educated dentists in the stomatological tradition. In 1987, the Spanish dental education system initiated movement from the stomatological model to the odontological. Both models have their respective strengths and weaknesses. This study surveyed professors and senior lecturers in Spain's public dental faculties to assess their perspectives on 10 items related to the tension between the odontological and the stomatological approach to preparing dentists. Amongst other things, the results of the study indicate that the respondents believe the odontological model, with its emphasis on strengthening technical qualifications, may not prepare individuals for dental practice better than the stomatology tradition; and that the odontological model results in the loss of the strength of the stomatological model, that is, the strong foundation in clinical medicine. The suggestion is advanced that European dental educators consider revising the odontology curriculum to strengthen the education of dental students in clinical medicine. A curriculum in which dental and medical students share the first 3 years of study could accomplish this. It is further suggested that subsequent years in the curriculum be flexible enough for students to earn degrees in both dentistry and medicine, if desired. Such an approach is not inconsistent with the accepted profile and competencies of the European dentist.

    2012-01-01

    In the last few years, Deoxyribonucleic Acid (DNA) analysis methods have been applied to forensic cases. Forensic dental record comparison has been used for human identification in cases where destruction of bodily tissues or prolonged exposure to the environment has made other means of identification impractical, that is, after fire exposure or mass disaster. Teeth play an important role in identification and criminology, due to their unique characteristics and relatively high degree of physical and chemical resistance. The use of a DNA profile test in forensic dentistry offers a new perspective in human identification. The DNA is responsible for storing all the genetic material and is unique to each individual. The currently available DNA tests have high reliability and are accepted as legal proofs in courts. This article gives an overview of the evolution of DNA technology in the last few years, highlighting its importance in cases of forensic investigation.

    Forensic dentistry plays a major role in body identification. The dental examination is very accurate and also, nowadays, in the time of a comprehensive fingerprint and DNA assessment, objectively supported. The identification, which is based on the dental documentation, leads up to 43-89% of a successful process. The purpose of the study is to describe the techniques employed by forensic odontology to identify human remains and also to provide details of some of the novel developments within this area. Comparative methods of dental identification of the unknown subject with pre-mortem clinical records, X-ray images, implant presence, superimposition and DNA analysis confirm the identity of the individual. It was shown that dental identification of a person is based on unique individual characteristics of the dentition and dental restorations, relative resistance of the mineralised dental tissues and dental restorations to changes resulting from decomposition and harsh environmental extremes such as conditions of temperature and violent physical forces.

    One of the consequences of placing amalgam restorations is that mercury is required for the trituration process. In turn, this raises the issue of the possible environmental impact of mercury. This report considers ways in which any impact can be modified and reduced by careful attention to mercury usage and hygiene in the dental practice, the use of filters and separators in waste water pipes and the appropriate disposal of waste contaminated with amalgam. The total amount of mercury discharged into the environment varies considerably in different parts of the world due to both natural and human activities. The extent to which dentistry adds to this total also varies according to local circumstances and requirements. Recommendations are given for further development of ways to reduce mercury discharge and for further research into the environmental impact of the metal.

    The proliferation of digital technology is impacting on the training and development of healthcare professionals. Research on the online behaviour of medical and pharmacy students indicates that social media poses a number of risks to the professional practice of healthcare professionals. General Dental Council guidelines on the use of social media also suggest that it has the potential to expose dental professionals to a variety of breaches of professional conduct. This paper explores the various ways social media can help, as well as hinder, the practice of dental professionalism. However, the lack of primary research on the social media behaviour of dental students and qualified dental practitioners alike acts as a barrier to increasing social media awareness within dentistry. The paper concludes by calling for more research-led discussion on the role social media plays in shaping our understanding of dental professionalism in the twenty-first century.

    The term LASER is an acronym for ‘Light Amplification by the Stimulated Emission of Radiation’. As its first application in dentistry by Miaman, in 1960, the laser has seen various hard and soft tissue applications. In the last two decades, there has been an explosion of research studies in laser application. In hard tissue application, the laser is used for caries prevention, bleaching, restorative removal and curing, cavity preparation, dentinal hypersensitivity, growth modulation and for diagnostic purposes, whereas soft tissue application includes wound healing, removal of hyperplastic tissue to uncovering of impacted or partially erupted tooth, photodynamic therapy for malignancies, photostimulation of herpetic lesion. Use of the laser proved to be an effective tool to increase efficiency, specificity, ease, and cost and comfort of the dental treatment. PMID:23833485

    Low level lasers, cold or soft lasers: These lasers do not produce thermal effects on tissues and induce photoreactions in cells through light stimulation which is called photobiostimulation. Power of these lasers is usually under 250mW. The main point differentiating low level lasers and high power ones is the activation of photochemical reactions without heat formation. The most important factor to achieve this light characteristic in lasers is not their power, but their power density for each surfa ceunit (i.e cm2). Density lower than 670mW/cm2, can induce the stimulatory effects of low level lasers without thermal effects. Low level lasers (therapeutic) used today as treatment adjunctive devices in medicine and dentistry. Numerous studies have been performed on the applications of low level lasers in patient pain reduction. Mechanisms of pain reduction with therapeutic lasers and their application are expressed, and the studies realized in this field are presented. PMID:25606308

    The use of medicines during pregnancy deserves special attention from dentists due to the potential risks to fetal development. The prescription of antimicrobial drugs during this period must be based not only on the etiology of the disease but also on the drug's effect on the embryo, which may be toxic, possibly leading to irreversible lesions. Interest in studies of the teratogenic effects of drugs increased in response to reports of the high incidence of phocomelia in patients treated with thalidomide. Although teratogenicity has long been known, pregnant women today are still exposed to this risk. The effects of drugs depend on the level of susceptibility of the fetus and on the period of exposure during pregnancy. In this context, and considering the paucity of studies on this subject in dentistry, the aim of this review was to offer an up-to-date compilation of data on the antimicrobial drugs most frequently used during pregnancy and the effects of their use.

    Reliable and safe provision of sedation and general anesthesia is dependent on continuous vigilance of patient's sedation depth. Failure to do so may result in unintended oversedation or undersedation. It is a common practice to observe sedation depth by applying subjective sedation scales and in case of general anesthesia, practitioner is dependent on vital sign assessment. The Bispectral Index System (BIS) is a recently introduced objective, quantitative, easy to use, and free from observer bias, and clinically useful tool to assess sedation depth and it precludes the need to stimulate the patient to assess his sedation level. The present article is an attempt to orient the readers towards utility and validity of BIS for sedation and general anesthesia in pediatric dentistry. In this article, we attempt to make the readers understand the principle of BIS, its variation across sedation continuum, its validity across different age groups and for a variety of sedative drugs.

    Foreign body aspiration (FBA) causes death in more than 300 children every year in the United States. Morbidity and mortality are increased in children due to narrow airways and immature protective mechanisms. Factors to consider in pediatric dentistry are: (1) the patient's age and behavior; (2) presence and extent of disability; (3) local anesthesia; (4) body positioning; and (5) loose teeth. FBA requires prompt recognition and early treatment to minimize potentially serious and sometimes fatal consequences. The purpose of this case report was to describe the aspiration of a stainless steel crown in a 5-year-old boy during conscious sedation. It also discusses how a prompt and accurate diagnosis, early referral, and immediate treatment helped prevent serious complications.

    Glass-ionomer cements (GICs) are mainstream restorative materials that are bioactive and have a wide range of uses, such as lining, bonding, sealing, luting or restoring a tooth. Although the major characteristics of GICs for the wider applications in dentistry are adhesion to tooth structure, fluoride releasing capacity and tooth-colored restorations, the sensitivity to moisture, inherent opacity, long-term wear and strength are not as adequate as desired. They have undergone remarkable changes in their composition, such as the addition of metallic ions or resin components to their composition, which contributed to improve their physical properties and diversified their use as a restorative material of great clinical applicability. The light-cured polymer reinforced materials appear to have substantial benefits, while retaining the advantages of fluoride release and adhesion. Further research should be directed towards improving the properties, such as strength and esthetics without altering its inherent qualities, such as adhesion and fluoride releasing capabilities.

    In 2004, a survey of the deans of U.S. and Canadian dental schools was conducted to determine the implant dentistry curriculum structure and the extent of incorporating implant dentistry clinical treatment into predoctoral programs. The questionnaire was mailed to the deans of the fifty-six dental schools in advance of the ADEA Implant Workshop conference held in Arizona in November 2004. Out of the fifty-six, thirty-nine responded, yielding a response rate of 70 percent. Thirty-eight schools (97 percent) reported that their students received didactic instruction in dental implants, while one school (3 percent) said that its students did not. Thirty schools (86 percent) reported that their students received clinical experience, while five schools (14 percent) reported that theirs did not. Four schools (10 percent) did not respond to this question. Fifty-one percent of the students actually receive the clinical experience in restoring implants, with the range of 5-100 percent. Of those schools that provide clinical experience in restoring implants, four schools (13 percent) reported that it is a requirement for them, while twenty-eight schools (88 percent) reported that it is not a requirement for them. Three schools (9 percent) did not respond. The fee for implants is 45 percent higher than a crown or a denture, with a range of 0-100 percent. Twenty-nine schools (85 percent) indicated that they did receive free components from implant companies, while five schools (15 percent) did not. The conclusions of this report are as follows: 1) most schools have advanced dental education programs; 2) single-tooth implant restorations are performed at the predoctoral level in most schools; 3) implant-retained overdenture prostheses are performed at the predoctoral level in most schools; 4) there is no predoctoral clinical competency requirement for surgical implant placement in all schools that responded to the survey; 5) there is no predoctoral clinical competency

    The concept of "Industrial Archaeology" was introduced in the 1950s in England in order to consider the branch of Archaeology that, in integration with engineering, architecture and economics, studies the industrial past, with the purpose of document, protect and exploite the industrial-cultural heritage. The systematic study of this kind of structures and artefacts need a wide range approach, that starts from the investigation about the object historic fonts until its complete qualitative and quantitative description, also considering the characteristics of the surrounding territory. This task often needs the integration of different survey techniques for data capturing and processing, in order to perform the 3D modeling and to analize the structural deformations of manufactured articles. The paper presents the surveying and monitoring activities on the important structure of the Casalecchio di Reno dyke, near Bologna. The first historic notes on the dyke are very old; they are dated back to the I millenium A. D. and report the news of a wooden barrage of the Reno canal. The construction of the actual structure is in the period 1360-1367 and suffered during the centuries numerous interventions and restores. The surveying activities on the dyke were realized in 2005-2006 and 2009 and involved different techniques (classical topography, high precision geometric levelling, range-based method by terrestrial laser scanning, digital photogrammetry, thermal imagery) integrated together in a unique local reference system, in order to study the stability and the movements of the structure in a established period of time and to realize a 3D model. Together with detail surveys on the single parts of the structure, an analysis at a larger territorial scale was performed by aerial photogrammetry, either using current imagery and historical data. The topographic measurements with traditional differential techniques have achieved a very high level precision and the realized

    The history of dental practice in Israel dates back to 1953, with the establishment of the Faculty of Dentistry at the Hebrew University. This article will discuss the early roots of American involvement in Israeli dentistry: beginning with the late Ottoman period in Palestine, through the British Mandate, the establishment of the State of Israel in 1948, and the institution of the Faculty of Dentistry at the Hebrew University of Jerusalem. It will introduce the central characters who promoted the professionalization process of dentistry in Israel--a process made possible by the 'Americanization' of the field: importing American knowledge and practice. Moreover, this article will demonstrate that although the majority of dentists and dental practitioners arrived in Palestine from Russia and from Germany, the main professional influence was American.

    2012-01-01

    Neogene (Miocene–Pliocene) sedimentary rocks of the northeastern Sierra Nevada were deposited in small basins that formed in response to volcanic and tectonic activity along the eastern margin of the Sierra. These strata record an early phase (ca. 11–10 Ma) of extension and rapid sedimentation of boulder conglomerates and debrites deposited on alluvial fans, followed by fluvio-lacustrine sedimentation and nearby volcanic arc activity but tectonic quiescence, until ~ 2.6 Ma. The fossil record in these rocks documents a warmer, wetter climate featuring large mammals and lacking the Sierran orographic rain shadow that dominates climate today on the eastern edge of the Sierra. This record of a general lack of paleo-relief across the eastern margin of the Sierra Nevada is consistent with evidence presented elsewhere that there was not a significant topographic barrier between the Pacific Ocean and the interior of the continent east of the Sierra before ~ 2.6 Ma. However, these sediments do not record an integrated drainage system either to the east into the Great Basin like the modern Truckee River, or to the west across the Sierra like the ancestral Feather and Yuba rivers. The Neogene Reno-Verdi basin was one of several, scattered endorheic (i.e., internally drained) basins occupying this part of the Cascade intra-arc and back-arc area.

    2011-07-08

    Amorphous Calcium Phosphate (ACP) is an essential mineral phase formed in mineralized tissues and the first commercial product as artificial hydroxyapatite. ACP is unique among all forms of calcium phosphates in that it lacks long-range, periodic atomic scale order of crystalline calcium phosphates. The X-ray diffraction pattern is broad and diffuse with a maximum at 25 degree 2 theta, and no other different features compared with well-crystallized hydroxyapatite. Under electron microscopy, its morphological form is shown as small spheroidal particles in the scale of tenths nanometer. In aqueous media, ACP is easily transformed into crystalline phases such as octacalcium phosphate and apatite due to the growing of microcrystalline. It has been demonstrated that ACP has better osteoconductivity and biodegradability than tricalcium phosphate and hydroxyapatite in vivo. Moreover, it can increase alkaline phosphatase activities of mesoblasts, enhance cell proliferation and promote cell adhesion. The unique role of ACP during the formation of mineralized tissues makes it a promising candidate material for tissue repair and regeneration. ACP may also be a potential remineralizing agent in dental applications. Recently developed ACP-filled bioactive composites are believed to be effective anti-demineralizing/remineralizing agents for the preservation and repair of tooth structures. This review provides an overview of the development, structure, chemical composition, morphological characterization, phase transformation and biomedical application of ACP in dentistry.

    Today's society is becoming increasingly unsafe for children: we frequently hear about new incidents of missing children, which lead to emotional trauma for the loved ones and expose systemic failures of law and order. Parents can take extra precautions to ensure the safety of their children by educating them about ways to protect themselves and keep important records of the child such as updated color photographs, fingerprints, deoxyribonucleic acid (DNA) samples, etc., handy. However, in spite of all efforts, the problem of missing children still remains. Developments in the field of dentistry have empowered dentists with various tools and techniques to play a pivotal role in tracing a missing child. One such tool is Toothprints, a patented arch-shaped thermoplastic dental impression wafer developed by Dr. David Tesini, a paediatric dentist from Massachusetts. Toothprints enables a unique identification of the missing children not only through the bite impression but also through salivary DNA. Besides the use of Toothprints, a dentist can assist investigating agencies in identifying the missing children in multiple ways, including postmortem dental profiling, labeled dental fixtures, DNA extraction from teeth, and serial number engraving on the children's teeth. More importantly, all these tools cause minimal inconvenience to the individual, making a dentist's role in tracking a missing child even more significant. Thus, the simple discipline of maintaining timely dental records with the help of their dentists can save potential hassles for the parents in the future. PMID:27051216

    2011-01-01

    Forensic dentistry as a science has evolved from simple methods of age estimation and bite-mark analysis, to a new era of genetic and serological investigations. DNA analysis in forensic science requires a sample or source from either an individual (living or dead) or a crime/incident site. The orofacial region is a good source of such material, due to the fact that certain oral tissues are relatively resistant to environmental degradation and destruction by thermal, electrical, and mechanical insult. Dentists may be called upon to provide samples and expert analysis in many such situations. Sources include soft and hard tissues of teeth and jaws, saliva, biopsy material, and mucosal swabs. Tissue samples should be handled with care, and correct protocol in collection and preparation has to be followed. This ensures a high yield of the required DNA. Hard tissues like teeth require specialized procedures to extract the genetic material. Research has shown that there is a wide variation in the quality and quantity of DNA extracted from different individuals from the same site even under similar conditions. This necessitates calibration of the various methods to achieve best results. DNA analysis can provide highly accurate identification if used correctly. Here a description of the various sources in the oral region has been provided from which samples could be forwarded to the forensic laboratory. Most commonly employed techniques of collection and handling for laboratory procedures have been outlined.

    Among ancient civilizations, India has been known to be a rich repository of medicinal plants. Herbal extracts have been used in traditional medicine for several thousand years. Some plants contain phytochemicals that have effects on the body. The use of phytotherapy is staging a comeback and an era of herbal renaissance is being revolutionized all over the globe. Herbs are a class of plants that are devoid of the woody tissue characteristic of shrubs or trees and have been known for their aromatic, flavoring, and medicinal values over the past centuries. Since the birth of contemporary practices, many have turned away from herbal therapies in favor of synthetic drugs. But these synthetic medicines can alter microbiota and have several side effects. However, the blind dependence on synthetics is over and people are returning to the naturals with the hope of safety and security. Hence, the search for alternative natural products continue. This review includes a few herbs, which can be used in dentistry as alternatives to allopathic medicines. PMID:27114947

    The objective of this study was to determine the prevalence, severity, and duration of postoperative pain in children undergoing general anesthesia for dentistry. This prospective cross-sectional study included 33 American Society of Anesthesiology (ASA) Class I and II children 4–6 years old requiring multiple dental procedures, including at least 1 extraction, and/or pulpectomy, and/or pulpotomy of the primary dentition. Exclusion criteria were children who were developmentally delayed, cognitively impaired, born prematurely, taking psychotropic medications, or recorded baseline pain or analgesic use. The primary outcome of pain was measured by parents using the validated Faces Pain Scale-Revised (FPS-R) and Parents' Postoperative Pain Measure (PPPM) during the first 72 hours at home. The results showed that moderate-to-severe postoperative pain, defined as FPS-R ≥ 6, was reported in 48.5% of children. The prevalence of moderate-to-severe pain was 29.0% by FPS-R and 40.0% by PPPM at 2 hours after discharge. Pain subsided over 3 days. Postoperative pain scores increased significantly from baseline (P < .001, Wilcoxon matched pairs signed rank test). Moderately good correlation between the 2 pain measures existed 2 and 12 hours from discharge (Spearman rhos correlation coefficients of 0.604 and 0.603, P < .005). In conclusion, children do experience moderate-to-severe pain postoperatively. Although parents successfully used pain scales, they infrequently administered analgesics. PMID:26650492

  11. Toxin yet not toxic: Botulinum toxin in dentistry.

    Paracelsus contrasted poisons from nonpoisons, stating that "All things are poisons, and there is nothing that is harmless; the dose alone decides that something is a poison". Living organisms, such as plants, animals, and microorganisms, constitute a huge source of pharmaceutically useful medicines and toxins. Depending on their source, toxins can be categorized as phytotoxins, mycotoxins, or zootoxins, which include venoms and bacterial toxins. Any toxin can be harmful or beneficial. Within the last 100 years, the perception of botulinum neurotoxin (BTX) has evolved from that of a poison to a versatile clinical agent with various uses. BTX plays a key role in the management of many orofacial and dental disorders. Its indications are rapidly expanding, with ongoing trials for further applications. However, despite its clinical use, what BTX specifically does in each condition is still not clear. The main aim of this review is to describe some of the unclear aspects of this potentially useful agent, with a focus on the current research in dentistry.

    This article is an updated review of the published literature on glass-ionomer cements and covers their structure, properties and clinical uses within dentistry, with an emphasis on findings from the last five years or so. Glass-ionomers are shown to set by an acid-base reaction within 2-3 min and to form hard, reasonably strong materials with acceptable appearance. They release fluoride and are bioactive, so that they gradually develop a strong, durable interfacial ion-exchange layer at the interface with the tooth, which is responsible for their adhesion. Modified forms of glass-ionomers, namely resin-modified glass-ionomers and glass carbomer, are also described and their properties and applications covered. Physical properties of the resin-modified glass-ionomers are shown to be good, and comparable with those of conventional glass-ionomers, but biocompatibility is somewhat compromised by the presence of the resin component, 2 hydroxyethyl methacrylate. Properties of glass carbomer appear to be slightly inferior to those of the best modern conventional glass-ionomers, and there is not yet sufficient information to determine how their bioactivity compares, although they have been formulated to enhance this particular feature.

  13. Formaldehyde in dentistry: a review of mutagenic and carcinogenic potential

    For many years there has been controversy over the value of antimicrobial drugs for intracanal dressings in endodontics. Formocresol, a formaldehyde compound, has evolved as the preferred drug for routine endodontic procedures, as well as pediatric endodontics. The increase in the use of formaldehyde has been complicated by the introduction of paraformaldehyde pastes for filling root canals. Neither of these formulas has ever been standardized. The doses are arbitrary, and the common dose of formocresol has been shown to be many times greater than the minimum dose needed for effect. The efficacy of paraformaldehyde pastes is questionable and remains clouded by inconclusive evidence, conflicting research, inadequate terminology, and a lack of convincing statistical evidence. The clinical use and delivery of formocresol and paraformaldehyde pastes remain arbitrary and unscientific. Formaldehyde has a known toxic mutagenic and carcinogenic potential. Many investigations have been conducted to measure the risk of exposure to formaldehyde; it is clear that formaldehyde poses a carcinogenic risk in humans. There is a need to reevaluate the rationale underlying the use of formaldehyde in dentistry particularly in light of its deleterious effects.

    Numerous written relicts, belletristic works (poems of Martial, Juvenal, Ovid etc.) indicate that oral hygiene and its tools (toothbrush, toothpick, use of tooth pastes and tooth-powder) were used long before our times. Already ancient people started to remove, file, dye and inlay teeth. The teeth were dyed red, green or black in Egypt, red or brown (with henna or betel) in India, white by Romans. The teeth decoration has a long but forgotten history. The most skillful and artistic work was done by the Maya's between 900 BC and 1500 AD. The modification of contours (more than fifty forms) of the incisors were practiced also in Mesoamerica. Dentistry was surely practiced in ancient Egypt, India, China, Greece and Rome, while odontology and especially suitable dental appliances arose only by Etruscan. Dental prosthesis, including bridges and simple retention bands were invented by the Etruscans 2500 years ago. These Etruscan bridges were worn mostly by females, suggesting that cosmetics was the principal dental concern. Some,--if not all--of the Roman and other prostheses have been purely ornamental. Orthodontic appliances are also Etruscan invention. The holes caused by caries were filled with garlic, incense, caraway seed in Egypt, with wood or lead in Rome, and with "silver-paste" (amalgam) in ancient China. The toothache was cured with poppy-tee, or hashish and nightshade plants (Solanaceae) in Egypt, Greece, Roman Empire while with coca (Erythroxylon coca) in South-America.

    Control of hemorrhage is one of the challenging situations dentists confront during deep cavity preparation and before impressions or cementation of restorations. For the best bond and least contamination it is necessary to be familiar with the hemostatic agents available on the market and to be able to choose the appropriate one for specific situations. This review tries to introduce the commercially available hemostatic agents, discusses their components and their specific features. The most common chemical agents that are widely used in restorative and prosthodontic dentistry according to their components and mechanism of action as well as their special uses are introduced. PubMed and Google Scholar were searched for studies involving gingival retraction and hemostatic agents from 1970 to 2013. Key search words including: “gingival retraction techniques, impression technique, hemostasis and astringent” were searched. Based on the information available in the literature, in order to achieve better results with impression taking and using resin bonding techniques, common hemostatic agents might be recommended before or during acid etching; they should be rinsed off properly and it is recommended that they be used with etch-and-rinse adhesive systems.

    To increase an orthopedic implant's lifetime, researchers are now concerned on the development of new titanium alloys with suitable mechanical properties (low elastic modulus-high fatigue strength), corrosion resistance and good workability. Corrosion resistance of the newly developed titanium alloys should be comparable with that of pure titanium. The effect of medical preparations containing fluoride ions represents a specific problem related to the use of titanium based materials in dentistry. The aim of this study was to determine the corrosion behavior of β titanium alloy Ti-39Nb in physiological saline solution and in physiological solution containing fluoride ions. Corrosion behavior was studied using standard electrochemical techniques and X-ray photoelectron spectroscopy. It was found that corrosion properties of the studied alloy were comparable with the properties of titanium grade 2. The passive layer was based on the oxides of titanium and niobium in several oxidation states. Alloying with niobium, which was the important part of the alloy passive layer, resulted in no significant changes of corrosion behavior. In the presence of fluoride ions, the corrosion resistance was higher than the resistance of titanium.

    The expansion of evidence-based dentistry (EBD) is essential to the continued growth and development of the dental profession. Expanding EBD requires increased emphasis on critical thinking skills during dental education, as noted in the American Dental Education Association's Competencies for the New General Dentist. In order to achieve this goal, educational exercises must be introduced to increase the use of critical thinking skills early in the dental curriculum, with continued reinforcement as students progress through subsequent years. Described in this article is one approach to increasing student exposure to critical thinking during the early basic science curriculum-specifically, within the confines of a traditional histology course. A method of utilizing the medical and dental research literature to reinforce and enliven the concepts taught in histology is described, along with an approach for using peer-to-peer presentations to demonstrate the tools needed to critically evaluate research studies and their presentation in published articles. This approach, which could be applied to any basic science course, will result in a stronger foundation on which students can build their EBD and critical thinking skills.

    After major disasters such as earthquakes, fires, floods, tsunami, bomb blasts or terrorist attacks, accurate, and early identification of the dead and injured becomes an utmost importance. Restorations, cariesteeth, missingteeth and/or prostheses are most useful aids for the dental identification. At times, only identifiable remains are a victim's partial or complete dentures. The central principle of dental identification is that postmortem dental remains can be compared with antemortem dental records which include, studycasts, radiographs, etc., to confirm the identity of the victims. Marking/labeling dentures have been considered an important aid in forensic dentistry. Other than finger printing, when compared with all the methods, the marking/labeling of dentures is an accurate and rapid method to identify the unknown victims. There are no standardized methods to follow, but dental practitioners needs to maintain some dental records of their patients. This may include documentation of the “marking of dentures.” The preparedness is the key to success in mass disaster identification. The aim of this review article is to discuss the methods of denture identification, advantages of denture labeling for the rapid identification during major disasters/accidents and the importance of maintaining the patient records.

    Speech adaptation after oral rehabilitation is based on a complex interaction of articulatory and myofunctional factors. The knowledge of basic phonetic principles may help clinicians identify phonetic problems associated with prosthodontic treatment. The purpose of this article is to illustrate basic phonetic terminology, standard Chinese (Putonghua) phonetics, and the anatomic structures relevant for dentistry. In cooperation with a Chinese linguistic specialist, Chinese articulators were selected and are described and compared with English phonetics. Established test words and sentences aid the identification of mispronounced articulators and their related dental structures. The pronunciation of most consonants and vowels in standard Chinese is similar to English, but some of them, such as the retropalatals (/zh/ [tʂ], /ch/ [thʂ], /sh/ [ʂ]), have notable differences. Palatal consonants (/j/ [tɕ], /q/ [tɕh], /x/ [ɕ]) are unique to the Chinese phonetic system and are not found in English phonetics. The comprehension of the basic anatomic regions involved in Chinese phonetics may help prosthodontists treat patients whose native language is standard Chinese.

    Dental caries is the most prevalent disease in humans, especially during early childhood. The restoration of such an extensive carious lesion should be done properly to reestablish their anatomy and hence their masticatory, phonetic, esthetic and space-maintainer functions in the dental arches. The consequences of premature loss of primary teeth are well known, namely the loss of vertical dimension of occlusion, tongue thrusting and mouth breathing habits, which can be the sources of future malocclusion. Satisfactory restoration of these teeth, improving esthetics, along with the management of space and function has always been a challenge for pediatric dentist. An ever increasing demand for esthetics has led to innovation and development of newer treatment modalities for these problems. In an attempt to widen the treatment options as biologically and conservatively as possible, tooth structure is used as a restorative material to rehabilitate severely destroyed tooth crowns. This technique consists of bonding sterile dental fragments, obtained either from the patient or from a tooth bank, to the teeth. Such a technique was termed as 'biological restoration'. This article aims at reviewing the evolution, techniques and outcome of such biological restorations. How to cite this article: MD Indira, Dhull KS, Nandlal B, Kumar PSP, Dhull RS.

    A dentist is frequently required to translate dental trauma into monetary value, for example after car accidents and/or work-related injuries. When called to act in this capacity a dentist should combine his/her biological and technical knowledge with a quality medico-legal knowledge. Calculation of economic (pecuniary) damages and non-economic (non-pecuniary) damages requires specific training in medico-legal matters and awareness of the inherent pitfalls. Expert Witnesses registered in Court are usually asked to perform this duty. Nevertheless, European countries have differences regarding dental damage evaluations as well as significant differences in the conditions required for registration as an Expert Witness in Court. A dental Expert Witness has precise responsibilities and is subject to civil or criminal proceedings (depending on the judicial system) if found wanting. In forensic/legal dentistry a medico-legal doctor should not work in isolation from a dentist in dental cases nor is it wise for a dentist to work in the courts without having had specific training regarding judicial disciplines relating to dental damages. In this preliminary work the authors investigate the principal differences in the judicial systems regarding the appointment of Expert Witnesses in both Italian and Croatian courts. The next step will expand this investigation through to European countries in order to marshal knowledge towards harmonization, best practice and a common ground for dental evaluation and claim compensations (in accordance with the Council of Europe Resolution 75 – 7 Compensation for physical injury or death).

    Conservative treatment which restores the function, aesthetics and protects remaining tooth structure, and what is the most important, the viability of the tooth pulp, is still needed. Dental fillings replace specialized tissues of the tooth that have been lost due to caries or injury. Any decision concerning the use of a particular restorative material should be individualized and based on the competence regarding the composition, properties and characteristics of the specific restorative material. This requires continuous updating of knowledge about available dental materials as well as education of patients who, according to actual models of dental care, should be active partners in the therapeutic process. The selection of restorative materials is often related to financial abilities of the patients, and more generally to the economic model of organized health care in a particular country. Nowadays, amalgam is increasingly dislodged by adhesive materials which permit to save more tooth structure and allow to preserve natural teeth for a longer time. In the nearest future we can expect further development of minimally invasive techniques and improvements of restorative materials, especially their mechanical properties like strength and wear resistance as well as biocompatibility. The article presents restorative materials used in modern dentistry.

    Forensic dentistry as a science has evolved from simple methods of age estimation and bite-mark analysis, to a new era of genetic and serological investigations. DNA analysis in forensic science requires a sample or source from either an individual (living or dead) or a crime/incident site. The orofacial region is a good source of such material, due to the fact that certain oral tissues are relatively resistant to environmental degradation and destruction by thermal, electrical, and mechanical insult. Dentists may be called upon to provide samples and expert analysis in many such situations. Sources include soft and hard tissues of teeth and jaws, saliva, biopsy material, and mucosal swabs. Tissue samples should be handled with care, and correct protocol in collection and preparation has to be followed. This ensures a high yield of the required DNA. Hard tissues like teeth require specialized procedures to extract the genetic material. Research has shown that there is a wide variation in the quality and quantity of DNA extracted from different individuals from the same site even under similar conditions. This necessitates calibration of the various methods to achieve best results. DNA analysis can provide highly accurate identification if used correctly. Here a description of the various sources in the oral region has been provided from which samples could be forwarded to the forensic laboratory. Most commonly employed techniques of collection and handling for laboratory procedures have been outlined. PMID:22022138

    In dental practice, local anesthesia causes pain, fear, and stress, and is frequently the reason that patients abandon treatment. Topical anesthetics are applied in order to minimize the discomfort caused by needle insertion and injection, and to reduce the symptoms of superficial trauma at the oral mucosa, but there are still no efficient commercially available formulations. Factorial design is a multivariate data analysis procedure that can be used to optimize the manufacturing processes of lipid nanocarriers, providing valuable information and minimizing development time. This work describes the use of factorial design to optimize a process for the preparation of nanostructured lipid carriers (NLC) based on cetyl palmitate and capric/caprylic triglycerides as structural lipids and Pluronic 68 as the colloidal stabilizer, for delivery of the local anesthetics lidocaine and prilocaine (both at 2.5%). The factors selected were the excipient concentrations, and three different responses were followed: particle size, polydispersity index and zeta potential. The encapsulation efficiency of the most effective formulations (NLC 2, 4, and 6) was evaluated by the ultrafiltration/centrifugation method. The formulations that showed the highest levels of encapsulation were tested using in vitro release kinetics experiments with Franz diffusion cells. The NLC6 formulation exhibited the best sustained release profile, with 59% LDC and 66% PLC released after 20h. This formulation was then characterized using different techniques (IR-ATR, DSC, DRX, TEM, and NTA) to obtain information about its molecular organization and its physicochemical stability, followed during 14months of storage at 25°C. This thorough pre-formulation study represents an important advance towards the development of an efficient pre-anesthetic for use in dentistry.

    We resolve complex spatial and temporal evolution of a long-duration earthquake sequence on multiple fault planes by combining high-precision relative relocations with over 350 first-motion focal mechanisms and applying physics-based, open-source software supported by both the USGS and CIG (Computational Infrastructure in Geodynamics) to investigate static and quasi-static stress changes during an 8 week foreshock period. Low-magnitude earthquake activity began on February 28, 2008 in the Mogul neighborhood west of urban Reno, NV and continued to build in intensity leading to the MW 5.0 mainshock on April 26, 2008. Initial locations are obtained by applying station and datum corrections to analyst-picked travel times using HYPOINVERSE then relocating the sequence via the HypoDD double-difference algorithm of Waldhauser and Ellsworth (2000) using both cross-correlated and catalog phase data on P and S arrivals. The final relocation set reveals a mechanism-supported temporal and spatial migration of seismicity on several distinct structures prior to the mainshock rupture. First-motion focal mechanisms are computed using the HASH code of Hardebeck and Shearer (2002). We apply the spatial and temporal stress inversion (SATSI) software (Hardebeck and Michael, 2006) to investigate variations in the stress field throughout the sequence. We integrate preliminary analysis of stress drops (ML ≥ 3.0) using an EGF-derived spectral ratio technique. Finally, we determine significant fault planes identified in the foreshock sequence and build a local 3D fault model. We systematically test various slip scenarios on these structures using both CIG's finite-element crustal deformation code PyLith and the USGS-supported Coulomb 3 program to explore how the foreshocks promote or inhibit failure on subsequent structures that may facilitate mainshock rupture.

    A growing need for broad dissemination of current scientific research and improved scientific literacy requires new models of professional development that allow for direct collaboration between educators and university researchers. One example is a project funded by the National Science Foundation (NSF) as part of a study titled, "Reconstructing 2500 years of environmental change at the periphery of Rome: Integrating paleoecology and socioeconomic history to understand human response to climate." This project involves a team of middle school teachers working with researchers at the University of Nevada, Reno (UNR) to gain first-hand knowledge in multidisciplinary research connecting science and society, and applies a similar approach in the classroom. In 2013, the team's science teacher traveled to Italy as a member of the science research group. A series of workshops introduced the remaining teachers to the research project. Teachers collaborated to develop a Project Based Learning (PBL) unit that incorporated Next Generation Science Standards and encompassed English, Social Studies, Math, and Science curricula using a pedagogical approach different from the single subject-based PBL's usually taught in their school district. The PBL unit draws on the NSF study and focuses on exploring the balance between economic and environmental issues surrounding local wetlands. In May 2014, 160 middle school students worked in groups to create and test a question about physio-chemical parameters in a nearby wetland and used these data to discuss local economic development. Initially, students claimed polarized views of environmental issues or economic development interests; however, during a multimedia session showcasing results, students communicated more informed perspectives that clearly incorporated knowledge gained from their own research. Some students were able to make recommendations for good practices involving planned economic development near the wetland

    Dentistry has evolved from a genuine medical practice to a mere business. From an ethical point of view it is asked whether this evolution creates more problems than it solves. The paper elaborates four arguments against this evolution and shows that aesthetics in dentistry which works only according to market categories runs the risk of loosing the view for the real need of patients. Dentistry which comprehends itself as part of a market will be nothing else than a part of a beauty industry which has the only aim to sell something, but not the aim to help people. Such a dentistry makes profit from the ideology of a society which serves only vanity, youthfulness and personal success and which is losing the sight for real values. The real value of man cannot be reduced to his appearance and medicine as an art should feel the obligation to resist these modern ideologies and should help people to get a more authentic attitude to themselves. If modern dentistry fails to think about these implications it will lose its identity as medicine, which would be too great a loss.

    The postdoctoral application and matching process in dental education is a high-stakes and resource-intensive process for all involved. While programs seek the most qualified candidates, applicants strive to be competitive to increase their likelihood of being accepted to a desirable program. There are limited data regarding either subjective or objective factors underlying the complex interplay between programs and applicants. This qualitative study sought to provide insight into the stakeholders' experiences and views on the matching process. Telephone and in-person interviews were conducted with ten pediatric dentistry program directors and ten recent applicants to pediatric dentistry programs in the United States in 2013-14. Participants were selected to represent the geographic (five districts of the American Academy of Pediatric Dentistry) and institutional (hospital- or university-based) diversity of pediatric dentistry programs. Interviews were recorded and transcribed verbatim. Veracity and need for more information were the themes most often articulated by both groups. The program directors most valued teachability and self-motivation as desirable applicant characteristics. The applicants relied primarily on subjective sources to gather information about programs and prioritized location and financial factors as pivotal for their rankings. Both groups appreciated the uniformity of the current application process and highlighted several weaknesses and areas for improvement. These results shed light on the postdoctoral matching process in pediatric dentistry via a qualitative description of stakeholders' experiences and viewpoints. These insights can serve as a basis for improving and refining the matching process.

    The scope of this paper is to describe characteristics of the scientific output in the area of public oral health in journals on public health and dentistry nationwide. The Scopus database of abstracts and quotations was used and eight journals in public health, as well as ten in dentistry, dating from 1947 to 2011 were selected. A research strategy using key words regarding oral health in public health and key words about public health in dentistry was used to locate articles. The themes selected were based on the frequency of key words. Of the total number of articles, 4.7% (n = 642) were found in oral health journals and 6.8% (n = 245) in public health journals. Among the authors who published most, only 12% published in both fields. There was a percentile growth of public oral health publications in dentistry journals, though not in public health journals. In dentistry, only studies indexed as being on the topic of epidemiology showed an increase. In the area of public health, planning was predominant in all the phases studied. Research to evaluate the impact of research and postgraduate policies in scientific production is required.

    The purpose of this study was to evaluate the perceptions and opinions of dental students from two different Dentistry Schools in Brazil, both known here as Dentistry Schools 1 and 2 about the Family Health Program--FHP. The study analyzed if the Dentistry Schools had any influence on the students, graduating professionals with humanitarian and social sensibility, which are considered very important prerequisites for those who wish to work on this governmental health program, as well as searching for professional expectation of the students. Individual questionnaires were applied by only one researcher among the students who took part in the study. Answers were analysed by the Epi-Info program and results showed that difficulties related to the job market may be influencing students to join the FHP. Results also reveal that students consider technician an important prerequisite for dentists who wish to work on this governmental program. Significant statistical differences between the students were found: those who were graduating in Dentistry School 1 seemed more adequate to FHP and the reason for this difference may be the Supervised Training Program, a unit available on this Dentistry School that enables the students face the reality of FHP, as well the social and economical reality of the families assisted by this program.

    Objective: The use of local anesthetics associated to vasoconstrictor agents in dentistry is thoroughly justified and is widely extended, but we cannot ignore the fact that anesthetic infiltration poses risk of complications throughout the dental treatment period. The objective of the present review is to document the reported effects the use of the local anesthetics most widely employed in dentistry, with or without association to vasoconstrictor agents may have in patients with any sort of cardiopathy. Study Design: We have searched for randomized clinical trials on the assessment of the cardiovascular effects of local anesthetics used in dentistry, without limits as regards age or sex, conducted in patients with any type of cardiopathy which were published during the last decade and were index-linked in Cochrane, Embase and Medline. Results: We have found six randomized clinical trials index-linked in Medline and Cochrane in the past ten years. These trials compare different types of anesthetics: lidocaine 2%, mepivacaine 2%, prilocaine 2% , associated or not to different vasoconstrictor concentrations such as adrenaline or felypressin. The cardiopathies affecting the patients included in the different trials range from hypertension, ischemic heart disease, arrythmias, chronic coronary disease to heart transplantation. Conclusions: The use of anesthetics associated to vasoconstrictor agents is justified in the case of patients with cardiopathies (once we get over the period in which any type of dental manipulation is contraindicated) and in controlled hypertensive patients. In any case, we must be very careful with the choice and execution of the anesthetic technique, being it possible to use a dose between 1.8 and 3.6 ml, on a general basis. Further studies are necessary to establish the effects of these drugs on severe hypertensive patients or in patients with other more advanced cardiopathies.

    2010-01-01

    The erbium-doped yttrium aluminium garnet (Er:YAG) laser has emerged as a possible alternative to conventional methods of bone ablation because of its wavelength of 2.94 μm, which coincides with the absorption peak of water. Over the last decades in several experimental and clinical studies, the widespread initial assumption that light amplification for stimulated emission of radiation (laser) osteotomy inevitably provokes profound tissue damage and delayed wound healing has been refuted. In addition, the supposed disadvantage of prolonged osteotomy times could be overcome by modern short-pulsed Er:YAG laser systems. Currently, the limiting factors for a routine application of lasers for bone ablation are mainly technical drawbacks such as missing depth control and a difficult and safe guidance of the laser beam. This article gives a short overview of the development process and current possibilities of noncontact Er:YAG laser osteotomy in oral and implant surgery. PMID:23662082

    The reasons that students choose certain specialties may be integral to the quality of specialty programs and the future of those specialties. The Harvard School of Dental Medicine (HSDM) has a high percentage (87.6 percent) of students who enroll in postgraduate programs. The goals of this study were to establish a baseline of factors that affect postgraduate program selection at HSDM and to determine if there was a significant difference in factor selection by gender, relationship status, graduation year, or choice to specialize versus choice to pursue advanced training in general dentistry. As a pilot study, we asked HSDM graduates from the classes of 2005 to 2007 to rank the importance of forty-two factors in selecting a field of dentistry and a particular program or institution within a specialty. Overall, students felt that intellectual content, challenging diagnostic problems, and possessing a special skill or talent unique to a specialty were the most important factors in choosing a field of dentistry. Influence of family members in dentistry was ranked as least important. In choice of a certain program or institution within a given field, clinical training and philosophy of training were ranked most highly. Students felt that the opportunity to moonlight was least important. Significant differences (p<0.05) were found regarding gender, relationship status, and students who chose to specialize versus those pursuing advanced general dentistry training. No significant differences were found among the students in different graduating classes.

  18. A rationale for the use of high-powered magnification or microscopes in general dentistry.

    PubMed

    Mamoun, John S

    2009-01-01

    This article argues that high-powered magnification (4x-6x or more) provides substantially more visual information for diagnosing and treating dental pathology compared to the use of unaided vision or entry-level 2.5x magnification. In all phases of general dentistry, the increased visual detail provided by high magnification reduces ambiguity in diagnosis and treatment decision-making, increases control in treatment implementation, allows a dentist to produce more ergonomic restorations that are less prone to recurrent decay, and arguably improves clinical outcomes compared to work performed with unaided vision. High magnification enhances a dentist's ability to diagnose caries and cracks in teeth, distinguish between different colors intraorally, detect the interfaces between different surfaces and materials, detect microscopic interferences in fixed and removable metal frameworks, adjust occlusal prematurities, and polish restorations. This article explains specific general dental applications for high-powered magnification in restorative dentistry, fixed and removable prosthodontics, endodontics, pediatric dentistry, periodontics, and oral surgery.

    The present review provides an insight into various potential areas of dentistry that are being invaded by nanotechnology based drugs and drug delivery systems. Current treatments for diseases of dental and oral structures rely on the use of classical pharmacological agents which, in some cases are limited by low efficacy and lack of selectivity to target cells. However, various nanostructures in drug delivery and their challenges in the field of dentistry have not been reviewed so far in the literature. The different treatment opportunities of importance include caries control restorations, tooth remineralisation, management of dentinal hypersensitivity, dental caries vaccine, management of oral biofilm, root canal disinfection, local anaesthesia and periodontal infection. The authors have also identified few dental applications demanding extensive research to emerge as a promising therapeutic strategy. We conclude by claiming that dentistry should follow the trend of probing matter at nanoscale to achieve a predictable treatment outcome.

    The aim of this study is to present data concerning hazardous waste management in the health area, with emphasis to the utilization of mercury in dentistry. The study was based on a bibliographic review regarding the use of mercury in dental fillings and its potential toxicological risks for patients and due to occupational exposure. The studies also take into consideration national and international recommendations on the use of mercury and its occupational exposure limits. The review of the literature reveals the potential toxic effects of mercury both on the environment and on human health. Given that the use of dental amalgam is still very frequent in dentistry, there is a need for safety regulations in order to minimize the risks posed by dental amalgam in dentistry proceedings based on technical guidelines for its use, discard and final disposal.

    There have been many developments in operative dentistry in recent years, including a progressive shift to the use of resin composites, rather than dental amalgam, in the restoration of posterior teeth. This shift allows the adoption of minimal intervention approaches, thereby helping to conserve and preserve remaining tooth tissues and structures. This paper presents the position of the Academy of Operative Dentistry European Section (AODES) in relation to posterior resin composites. The AODES considers adhesively bonded resin composites of suitable composition and properties to be the "material of choice" for use in direct minimal intervention approaches to the restoration of posterior teeth. In so doing, the AODES emphasises the importance of the practice of evidence-based minimal intervention dentistry, including the use of refurbishment and repair techniques to extend the longevity of restorations. Guidance, based on best available evidence, has been made in relation to certain aspects of resin composite placement techniques in posterior teeth.

    Although the use of computer color matching can reduce the influence of subjective factors by technicians, matching the color of a natural tooth with a ceramic restoration is still one of the most challenging topics in esthetic prosthodontics. Back propagation neural network (BPNN) has already been introduced into the computer color matching in dentistry, but it has disadvantages such as unstable and low accuracy. In our study, we adopt genetic algorithm (GA) to optimize the initial weights and threshold values in BPNN for improving the matching precision. To our knowledge, we firstly combine the BPNN with GA in computer color matching in dentistry. Extensive experiments demonstrate that the proposed method improves the precision and prediction robustness of the color matching in restorative dentistry.

    Recent developments in research have been based on the maintenance and regeneration of natural organs and tissues; among such developments is the use of growth factors (GFs). The use of basic fibroblastic growth factors (bFGF) may be indicated in different disciplines of dentistry such as periodontics and dental traumatology. These cells' ability to induce proliferation and differentiation of cells may make GFs a useful source for the development of natural structures. This mini-review will discuss how bFGF can be beneficial to dentistry in relation to 1) re-implantation/autotransplantation of avulsed teeth and 2) periodontal regeneration.

    The ability to conduct efficient literature searches is fundamental to the practice of evidence-based dentistry. In the second part of this series on evidence-based dentistry, strategic literature search techniques are discussed. MEDLINE, because of its breadth, depth and continuous maintenance by the U.S. National Library of Medicine (NLM), is the best source of evidence for health care. Although there are many gateways to MEDLINE, this paper highlights the user-friendly versions of MEDLINE offered free on the Internet by the NLM. The use of well-established search tactics and the unique features of the NLM sites facilitate rapid, effective literature searches.

    Forensic odontology explores the field of human identification through dental tissues in cases where there is destruction of body tissues in criminal investigations and mass disasters. Forensic odontology involves dentists participating in legal and criminal issues. Parameters such as age and gender identification are important in identifying the person or persons. Over the last two decades, the molecular aspect of forensic sciences has increased, and these molecular techniques now provide a novel approach to forensic odontology. Molecular advancements in science like DNA analysis has extended the range of forensic dentistry as teeth possess the character of resistance toward physical or chemical aggressions. Teeth provide the abundant space for DNA, and hence teeth represent an excellent source of genomic DNA. The present paper focusses on molecular advancements in the field of forensic odontology.

    Introduction: Previous studies have shown that the state of oral health in the area of Podrinje Canton is really poor. Taking into account that in the last five years are implemented two projects in the municipality it is necessary to examine the impact of preventive measures in dentistry on the oral health. The research goals are: a) To evaluate the impact of continuing education and local fluoridation on the state of oral health; b) To analyze the economic importance of preventive measures. The examinees and methods: For the purpose of the research on activities of continuing education on the importance of oral health and local fluoridation of teeth and to determine the economic aspects of the application of preventive measures is tested and reviewed 900 students from fourth to ninth grade. The children were divided into three groups of 300 students in each group: a) In the first group of children is carried out continuous education about proper tooth brushing and the importance of oral hygiene and local fluoridation twice a year during the last three years, b) In the second group children carried out local fluoridation twice a year during the last three years while in the third group, there were no continuous prevention measures; c) Used is a single questionnaire for all respondents. Data obtained in this study were analyzed by descriptive and inferential statistical methods. The results and conclusions: The importance of continuing education and local fluoridation is clearly reflected in the different values DMF-index, which was the subject of research. In the first group, in which is carried out continuous education and local fluoridation value of DMF index was 2.7, in the second group with local fluorination this value was 3.56, while in the third group, in which is not implemented preventive measures, the value DMF- index was 5.93. From an economic point the preventive measures are the cheapest, most effective and the best solution in order to maintain oral

    The University of Miami (UM) deployed a sequential two-photon laser-induced fluorescence (2P-LIF) instrument for the in situ measurement of gaseous elemental mercury, Hg(0), during the Reno Atmospheric Mercury Intercomparison Experiment (RAMIX) campaign. A number of extended sampling experiments, typically lasting 6-8 h but on one occasion extending to ˜ 24 h, were conducted, allowing the 2P-LIF measurements of Hg(0) concentrations to be compared with two independently operated instruments using gold amalgamation sampling coupled with cold vapor atomic fluorescence spectroscopic (CVAFS) analysis. At the highest temporal resolution, ˜ 5 min samples, the three instruments measured concentrations that agreed to within 10-25 %. Measurements of total mercury (TM) were made by using pyrolysis to convert total oxidized mercury (TOM) to Hg(0). TOM was then obtained by difference. Variability in the ambient Hg(0) concentration limited our sensitivity for measurement of ambient TOM using this approach. In addition, manually sampled KCl-coated annular denuders were deployed and analyzed using thermal dissociation coupled with single-photon LIF detection of Hg(0). The TOM measurements obtained were normally consistent with KCl denuder measurements obtained with two Tekran speciation systems and with the manual KCl denuder measurements but with very large uncertainty. They were typically lower than measurements reported by the University of Washington (UW) Detector for Oxidized Hg Species (DOHGS) system. The ability of the 2P-LIF pyrolysis system to measure TM was demonstrated during one of the manifold HgBr2 spikes but the results did not agree well with those reported by the DOHGS system. The limitations of the RAMIX experiment and potential improvements that should be implemented in any future mercury instrument intercomparison are discussed. We suggest that instrumental artifacts make a substantial contribution to the discrepancies in the reported measurements over the

    Prof. Dr. Gheorghe Bilaşcu (1863–1926) was one of the founders of the Romanian Faculty of Medicine in Cluj. At this Faculty, in 1919/1920 he created the department and the clinic of dentistry. These two achievements were accomplished for the first time in Romania. Normally, his contribution should have been appreciated both during his life and after his death. Also, his name would be expected to be present in the large majority of Romanian medico-historians dictionaries, treatises, papers etc. Unfortunately, his posthumous appreciation was not as Bilaşcu would have deserved. In our paper we present the recognition of Gh. Bilaşcu’s contributions in the Romanian history of dentistry between 1926–2013. We divided this period into three intervals: from 1926 to 1948, the communist era, and after the anticommunist revolution (1990-present). In the first interval the achievements of Bilaşcu in the field of dentistry were very much appreciated and they were mentioned in a correct way in different medico-historical sources of information. During the communist era the name of Bilaşcu was omitted in some dictionaries, courses etc. After 1990, the important role of Bilaşcu in Romanian dentistry was put into its important place in the majority of Romanian history of medicine sources of information.

    Previously dentists focused on repair and maintenance of function. However, the emphasis of many patients and dentists is now on esthetics. Often there is a need for the disciplines of orthodontics, periodontics, restorative dentistry, and maxillofacial surgery to work together in order to achieve optimum results. Currently the sequencing planning process begins with esthetics and then function, structure, and ultimately biology.

    Studies have shown the use of laser therapy at points of acupuncture as an alternative to metal needles. The scientific literature in the area of laser acupuncture is rather large; however, the actual mechanisms and effects have not yet been proven in detail. Therefore, the current manuscript reviews the existing literature regarding the effects of laser acupuncture in Dentistry, seeking treatment modalities in which this technique is used and which are able to generate positive clinical results. Thus, the literature survey was conducted in electronic databases--Medline/Pubmed, VHL and Science Direct--using the uniterms "alternative medicine", "low-power laser and acupuncture", "laser acupuncture and dentistry" and "laser therapy and acupuncture". Retrospective and prospective clinical studies were considered. According to the findings of the literature, laser therapy at points of acupuncture was effective for the treatment of various orofacial problems encountered in dentistry, but there are still many differences among the parameters used for irradiation and there is a lack of important information reported by the studies, such as the wavelength, dose, power density, irradiation time and frequency, points of acupuncture selected for irradiation and therapy outcomes. Although these results indicate the potential benefit of the use of laser therapy at points of acupuncture on Dentistry, further double-blinded, controlled clinical trials should be carried out in order to standardize protocols for clinical application.

    2010-01-01

    Evidence-based Dentistry (EBD), like Evidence-based Medicine (EBM), was born in order to seek the “best available research evidence” in the field of dentistry both in research and clinical routine. But evidence is not clearly measurable in all fields of healthcare: in particular, while drug effect is rather independent from clinician’s characteristics, the effectiveness of surgical procedures is strictly related to surgeon’s expertise, which is difficult to quantify. The research problems of dentistry have a lot in common with other surgical fields, where at the moment the best therapeutic recommendations and guidelines originates from an integration of evidence-based medicine and data from consensus conferences. To cope with these problems, new instruments have been developed, aimed at standardizing clinical procedures (CAD-CAM technology) and at integrating EBM achievements with the opinions of expert clinicians (GRADE System). One thing we have to remember however: it is necessary to use the instruments developed by evidence-based medicine but is impossible to produce sound knowledge without considering clinical expertise and quality of surgical procedures simultaneously. Only in this way we will obtain an evidence-based dentistry both in dental research and clinical practice, which is up to third millennium standards. PMID:20871758

    Based on the regulatory framework and an overview of dentistry in supplementary health, this paper discusses the specifics of the dental sector with respect to health promotion policies and quality of health care services proposed by the National Supplementary Health Agency (ANS). The State's activities in supplementary health are based on law 9.656/98, which defines the relations between operators, products and their beneficiaries, and law 9.961/2000, which created the ANS. Concomitantly there was a great increase in dentistry in the private health plan market, because of changes in the practices of the profession. This required the need to know the logic of the organization of the services regarding the assistance provided and the model of care. The ANS develops measures to encourage operators to implement health promotion programs, striving for an integral care model. At the same time, it promotes the qualification policy of supplementary health care, with emphasis on the scope of care, though in dentistry the focus of evaluation is still individual and fragmented care. Indeed, the great challenge of dentistry is making it a public health policy, accessible to all, and the qualification of dental care in supplementary health.

    Empirical concepts describe the direction of the masticatory stress dissipation in the skull. The scientific evidence of the trajectories and the magnitude of stress dissipation can help in the diagnosis of the masticatory alterations and the planning of oral rehabilitation in the different areas of Dentistry. The Finite Element Analysis (FEA) is a tool that may reproduce complex structures with irregular geometries of natural and artificial tissues of the human body because it uses mathematical functions that enable the understanding of the craniofacial biomechanics. The aim of this study was to review the literature on the advantages and limitations of FEA in the skull biomechanics and Dentistry study. The keywords of the selected original research articles were: Finite element analysis, biomechanics, skull, Dentistry, teeth, and implant. The literature review was performed in the databases, PUBMED, MEDLINE and SCOPUS. The selected books and articles were between the years 1928 and 2010. The FEA is an assessment tool whose application in different areas of the Dentistry has gradually increased over the past 10 years, but its application in the analysis of the skull biomechanics is scarce. The main advantages of the FEA are the realistic mode of approach and the possibility of results being based on analysis of only one model. On the other hand, the main limitation of the FEA studies is the lack of anatomical details in the modeling phase of the craniofacial structures and the lack of information about the material properties.

    The use of a randomized controlled trial (RCT) research design is considered the gold standard for conducting evidence-based clinical research. In this present study, we aimed to assess the quality of RCTs in dentistry and create a general foundation for evidence-based dentistry on which to perform subsequent RCTs. We conducted a systematic assessment of bias of RCTs in seven general dentistry journals published between January 2011 and March 2012. We extracted study characteristics in duplicate and assessed each trial's quality using the Cochrane Risk of Bias tool. We compared risk of bias across studies graphically. Among 1,755 studies across seven journals, we identified 67 RCTs. Many included studies were conducted in Europe (39%), with an average sample size of 358 participants. These studies included 52% female participants and the maximum follow-up period was 13 years. Overall, we found a high percentage of unclear risk of bias among included RCTs, indicating poor quality of reporting within the included studies. An overall high proportion of trials with an "unclear risk of bias" suggests the need for better quality of reporting in dentistry. As such, key concepts in dental research and future trials should focus on high-quality reporting.

    2013-05-01

    Motivational interviewing (MI) is a client-centred, directive, therapeutic approach that enhances clients' readiness to change by exploring their ambivalence about doing so, thus increasing their motivation to change, and by helping them to commit to the process of change. MI is now being applied to dentistry in the area of oral health e.g. smoking cessation and the prevention of early childhood caries. This aligns dentistry with other healthcare professions in their focus on utilising MI to bring about behavioural change. This paper focuses on how the profession of dentistry would benefit from examining how to integrate MI both in undergraduate teaching and practice. Currently the teaching focus in relation to MI has centred on the theoretical content and less on underlying philosophy. This paper explores how a teaching philosophy, as delivered in the behavioural science programme in the School of Dentistry, University College Cork, Ireland, can provide a framework for teaching MI. Key components within this teaching philosophy are: teaching for understanding, developing reflective practice and student-centred teaching.

    This revised Clinical Guideline in Paediatric Dentistry replaces the previously published sixth guideline (Fayle SA. Int J Paediatr Dent 1999; 9: 311-314). The process of guideline production began in 1994, resulting in first publication in 1997. Each guideline has been circulated widely for consultation to all UK consultants in paediatric dentistry, council members of the British Society of Paediatric Dentistry (BSPD), and to people of related specialities recognized to have expertise in the subject. The final version of this guideline is produced from a combination of this input and thorough review of the published literature. The intention is to encourage improvement in clinical practice and to stimulate research and clinical audit in areas where scientific evidence is inadequate. Evidence underlying recommendations is scored according to the SIGN classification and guidelines should be read in this context. Further details regarding the process of paediatric dentistry guideline production in the UK is described in the Int J Paediatr Dent 1997; 7: 267-268.

    Background: As in other fields of medicine, scientific production in the field of dentistry has significant placement. This study aimed at quantitatively and qualitatively evaluating Iranian researchers’ scientific output in the field of dentistry and determining their contribution in each of dentistry subfields and branches. Methods: This research was a scientometric study that applied quantitative and qualitative indices of Web of Science (WoS). Research population consisted of927indexed documents published under the name of Iran in the time span of 1993-2012 which were extracted from WoS on 10 March 2013. The Mann-Whitney test and Pearson correlation coefficient were used to data analyses in SPSS 19. Results: 777 (83. 73%) of indexed items of all scientific output in WoS were scientific articles. The highest growth rate of scientific productionwith90% belonged to endodontic sub field. The correlation coefficient test showed that there was a significant positive relationship between the number of documents and their publication age (P < 0. 0001). There was a significant difference between the mean number of published articles in the first ten- year (1993-2003) and that of the second one (2004-2013), in favor of the latter (P = 0. 001). Conclusions: The distribution frequencies of scientific production in various subfields of dentistry were very different. It needs to reinforce the infrastructure for more balanced scientific production in the field and its related subfields. PMID:26635439

    Introduction Various studies have reported poor awareness and knowledge of dentistry in the Nigerian population. There is, however, paucity of information assessing the knowledge and awareness of medical doctors/students and nurses about dentistry. The present study is aimed at determining the knowledge and awareness of medical doctors/students and nurses about dentistry. Methods Self-administered questionnaires were randomly distributed among medical doctors/students, and nurses of Obafemi Awolowo Teaching Hospitals’ Complex, Ile-Ife, Nigeria. Information collected using the questionnaire included participants’ biodata, questions evaluating dental awareness, knowledge of systemic and oral health connections as well as referral practices. The data analysis was done with STATA version 11 software. Results A total of 300 questionnaires were randomly distributed among doctors/students and nurses, 206 were returned (response rate of 69%). Of the returned questionnaires, 129(63%) were males and 77(37%) were females. There were 42 medical doctors, 49 nurses and 115 medical students. The mean age of the participants was 26.7 years (SD 5.2). Majority (99.5%) was aware of dental profession, but 92% had never referred patients for dental consultation. One third (31%) of medical doctors believed that Ludwig angina was a cardiac disease. A large proportion of the respondents (61%) see no need for routine dental visit while 27% would want to visit the dentist only when they had a dental complaint. Conclusion Although a large percentage of the participants claimed to be aware of dentistry, our findings revealed low level of knowledge and attitude to Dentistry. Efforts should be made towards closing this knowledge gap to achieve efficient oral health. PMID:27303588

    Many people with special needs (PSN) have difficulty having good oral health or accessing oral health services because of a disability or medical condition. The number of people with these conditions living in community settings and needing oral health services is increasing dramatically due to advances in medical care, deinstitutionalization, and changing societal values. Many of these individuals require additional supports beyond local anesthesia in order to receive dental treatment services. The purpose of this consensus statement is to focus on the decision-making process for choosing a method of treatment or a combination of methods for facilitating dental treatment for these individuals. These guidelines are intended to assist oral health professionals and other interested parties in planning and carrying out oral health treatment for PSN. Considerations for planning treatment and considerations for each of several alternative modalities are listed. Also discussed are considerations for the use of combinations of modalities and considerations for the repeated or frequent use of these modalities. Finally, the need to advocate for adequate education and reimbursement for the full range of support alternatives is addressed. The Special Care Dentistry Association (SCDA) is dedicated to improving oral health and well being of PSN. The SCDA hopes that these guidelines can help oral health professionals and other interested individuals and groups to work together to ensure that PSN can achieve a "lifetime of oral health."

    "Identification through forensic science is an art of giving the corpse a name A real life detective work that would put even Sherlock Homes to shame." Forensic dentistry deals with proper handling and examination of dental evidence and proper evaluation and presentation of dental findings in interest of justice. The Prosthodontists are playing a very important role in forensic dentistry as they are concerned with fabrication of various prosthesis which can serve as an important tool for identification. Identification is essential requirement of any medico-legal investigation because a wrong identity may pose a problem in delivering justice. This article describes the different methods for identification/marking of the complete dentures, removable partial dentures and fixed partial dentures and the importance of denture marking in forensic investigatory purposes. The PubMed, Ebsco and Google search engines were used to gather the articles.

    Data from available literature point to an early beginning of Forensic Dentistry in Croatia relating to a post-mortem examination of a female patient after a dental procedure in the 1930s. Later on, there were several mass casualties due to collisions and airplane crashes and a railway accident at the Zagreb Main Railway Station wherein the identity of the victims was established based on dental features. Foreign experts in forensics helped identify those victims, particularly forensic dentists because this specialty was almost unknown in our region at the time. During the twenty-year period of the development of Forensic Dentistry at the University of Zagreb, the School of Dental Medicine, the city of Zagreb and Croatia have become internationally recognised on the forensic map of the world.

    Dentistry increasingly uses Information and Communication Technology (ICT), which has impact on teaching, research, the profession and dental care in general. However, there is a lack of valid information on ICT resources and use in Latin America. This was a descriptive, cross-sectional, multi-center, interdisciplinary study, the aim of which was to conduct a survey on how extensively ICT is used in Dentistry in Latin American countries by enquiring into two primary components: 1) use of ICT in student training and 2) use of ICT by professionals in consulting rooms and services. Two questionnaires on ICT were prepared: one for teachers/researchers and another for students/professionals. We received 94 answers from teachers/researchers at universities in the region providing information on ICT resources for teaching (type and implementation) and 221 answers from professionals (personal use and use in healthcare). Data are presented as absolute relative frequencies and analyzed quantitatively as percentages.

    Clinical dental work is placing increasing demands on a clinician's vision as new techniques that require fine detail become more common. High hand-eye coordination requires good visual acuity as well as other psychological and neurological qualities such as stereopsis. Stereopsis (three-dimensional vision) is the highest form of depth perception obtained by visual disparity of images formed in the retinas of two eyes. It is believed to confer functional benefits on everyday tasks such as hand-eye coordination. Although its role in depth perception has long been established, little is known regarding the importance of stereopsis in dentistry. This article reviews the role of stereopsis in everyday life and the available literature on the importance of stereopsis in dentistry.

    This manuscript reports the treatment trends in a pediatric dentistry clinic from 1980 to 1992 and discusses their implication in clinical teaching. Analysis of the records of the senior year pediatric dentistry students indicated: no significant change with time in the patients/student ratio, the number of preformed crowns, pulpotomies, and pulpectomies by student or by patient; a significant decrease in the number of one-surface and > or = 2-surface restorations by student and by patient; a significant increase in the number of pit-and-fissure sealants and preventive resin restorations by student and by patient. During the thirteen-year period, the students performed an average of 7.3 one-surface; 12.9 > or = 2-surface restorations; 5.5 preformed crowns; 6.4 pit-and-fissure sealants; 2.4 pulpotomies. There was a significant increase with time in the number of students who performed pit-and-fissure sealants.

  16. Cold Atmospheric Plasma: methods of production and application in dentistry and oncology

    PubMed Central

    2013-01-01

    Cold Atmospheric Plasma is an ionized gas that has recently been extensively studied by researchers as a possible therapy in dentistry and oncology. Several different gases can be used to produce Cold Atmospheric Plasma such as Helium, Argon, Nitrogen, Heliox, and air. There are many methods of production by which cold atmospheric plasma is created. Each unique method can be used in different biomedical areas. In dentistry, researchers have mostly investigated the antimicrobial effects produced by plasma as a means to remove dental biofilms and eradicate oral pathogens. It has been shown that reactive oxidative species, charged particles, and UV photons play the main role. Cold Atmospheric Plasma has also found a minor, but important role in tooth whitening and composite restoration. Furthermore, it has been demonstrated that Cold Atmospheric Plasma induces apoptosis, necrosis, cell detachment, and senescence by disrupting the S phase of cell replication in tumor cells. This unique finding opens up its potential therapy in oncology. PMID:24083477

    1. The ADA Council on Dental Education Commission on Accreditation, using the Standards for undergraduate education and current National Board scores, does not believe there has been a deemphasis in prosthodontic knowledge and skill. This opinion is not shared by program Directors or representatives of the laboratory industry. The Council on Dental Education has a mechanism for periodic review in place. State Boards of Dental Examiners did not respond. 2. Teaching experience for residents or graduate students should be encouraged in advanced education programs in prosthodontics as an elective or be limited to no more than 10% of the curriculum time. 3. The American Board of Prosthodontics would not comment on any changes regarding the clinical or didactic knowledge of candidates. 4. Meaningful research is not possible within the current minimum 22-month program duration. 5. Accredited advanced education programs in prosthodontics are currently meeting the standard guidelines for clinical and didactic experiences. 6. Accredited advanced education programs in prosthodontics are currently satisfying the requirements on supervision and faculty; however, the data from the annual reports suggest a marked decrease in staff support and amount of time that program directors are devoting to the program. 7. Expanding the curriculum to include implant prosthodontics will require lengthening the curriculum time. 8. TMJ therapy and geriatric dentistry need to be better defined in the educational guidelines. 9. The criterion-based examination currently given by the American Board of Prosthodontics clearly delineates acceptable, marginal, and unacceptable levels of performance. 10. Program directors desire more "feedback" from the American Board of Prosthodontics on the performance of candidates.(ABSTRACT TRUNCATED AT 250 WORDS)

    Communication skills have long been associated with practice success in dentistry. The Commission on Dental Accreditation's standards state that "Graduates must be competent in the application of the fundamental principles of behavioral sciences" and that "Graduates must be competent in managing a diverse patient population and have...interpersonal and communications skills." A recent survey of U.S. dentists found an underutilization of communication skills by general dentists. The University of Tennessee College of Dentistry strives for continuous improvement and has implemented an innovative behavioral science curriculum to improve students' communication skills, consistent with the College's "patient-centered, comprehensive care" philosophy. We describe the design and implementation of our "Patient-Centered Dentistry" course, in which third-year dental students practice communication skills with simulated patients in the Kaplan Clinical Skills Center on the UTHSC campus. The clinical simulations involve the following scenarios: The Initial Interview with a Patient, Presenting a Treatment Plan, Treating Patients with Fear and Anxiety, Interviewing Considerations for Difficult Patients, Delivering Distressing News to Patients, and Coping with a Drug-Seeking Patient. Student simulations were videotaped and assessed by course instructors as well as clinical faculty, and students received immediate feedback by instructors and clinical faculty after their simulations. Students were provided with the opportunity to view their simulation performance and to reflect on their performance in order to recognize their communication strengths as well as areas for improvement. The use of simulation experiences is becoming a widespread and expected practice in health care education. The Patient-Centered Dentistry course provides students with the opportunity to experience the kinds of real-life situations that they would experience in dental practice, without risks to patients

    In the past few decades, there has been an increase in demand for safety evaluation and control of dental materials used daily in dentistry; however, this task is difficult and cumbersome. Dental materials that are passive and do not react with the oral environment will be more stable and have superior durability. It is expected that dental materials will be universally accepted and will not cause harm or injury to the surrounding structures in the oral cavity. This is an entirely negative approach to the material tolerance and biocompatibility, and hides the possibility that some positive gains can be achieved. Side-effects of dental materials are believed to be rare, and generally, those that have been reported are mild. There are wide varieties of materials used in dentistry, which include liners, irrigants, intracanal filling materials, intracanal medicaments, prosthetic materials, restorative materials, subgingival implants, and mouth rinses. Therefore, in this study, the biocompatibility of various commonly-used clinical materials used in contemporary dentistry was discussed.

    The capacity to locate, access, and appraise information is an important skill required for success in dental school and beyond. An interdisciplinary course was implemented to teach first-year dental students at the University of Texas Health Science Center at Houston Dental Branch about evidence-based dentistry, search strategies, critical appraisal of the literature, and dental informatics. Students learned to develop a clinical question, conduct a search to find answers to that question, and critically appraise one of the retrieved resources. Over a period of four years, a total of 259 dental students completed a questionnaire that requested their assessment of this course. Seventy-five percent of the respondents agreed or strongly agreed that they learned to effectively search databases such as the Cochrane Collaboration and PubMed and to critically appraise websites and journal articles and that the information on evidence-based dentistry and critical thinking skills was valuable. In response to open-ended questions, approximately 35 percent of the respondents mentioned the importance of learning to search PubMed and Cochrane databases. Approximately 20 percent of the respondents felt the course did not contain new information. These results indicated the effectiveness of the course in familiarizing the students with the capacity of online resources to help them locate, access, and appraise information pertinent to oral health issues and the practice of dentistry. A future goal is to integrate information and skills associated with evidence-based practice into other courses in the dental curriculum.

    Introduction Magnetic Resonance Imaging (MRI), being a technique with huge potential, has become the primary diagnostic investigation for many clinical problems. Its application now has been successfully used in dentistry to maximize the diagnostic certainty. Aim The present review aims to analyze the applicability, feasibility and efficacy of MRI in the field of dentistry. Materials and Methods A literature search was performed in main databases like Pub Med Central, Cochrane Library, Embase and Google Scholar from 1970 up to December 2015. The 2672 titles that appeared, 25 fulfilled the criteria and were included in the review. Two articles were hand searched and three articles through e-mail were also included. Results The review highlights the increasing role of MRI in dentistry. In the available literature, it was found that T1 and T2 weighted images were the acceptable diagnostic images for detection of dental related diseases. Conclusion MRI can be used in diagnosis and treatment planning of implants, jaw lesions, diseases of Temporomandibular Joints (TMJ), orthodontic treatment, endodontic treatment etc., to achieve better prognosis.

    2013-03-01

    The concept of leadership means different things to different people. At present there is no single definition of leadership nor an established theoretical approach. Despite this, leadership in the clinical environment is becoming increasingly cited as an important component in the transition of the National Health Service (NHS) and in the development of clinician led services. In medicine, clinical commissioning groups (CCGs) will soon be operational and the Department of Health (DH) seeks to establish a similar approach in dentistry, where local clinicians drive forward a quality agenda with a focus on patient outcomes. To facilitate this, the NHS Commissioning Board (NHSCB) are in the process of developing Local Professional Networks (LPNs) for dentistry. Given this shift towards localism and clinician led services it would appear that leadership will have a significant role in both medicine and dentistry. This paper explores what leadership is, before determining why it might be important in providing a clinician-led, patient-based and outcomes-focused service.

    Oral disease continues to be a major problem in Australia impacting quality of life, the economy and broader health system. Although the understanding of caries and periodontal disease has improved along with increased government support, oral diseases continue to be the most prevalent among all health conditions. This is despite unprecedented levels of funding in the Chronic Disease Dental Scheme and the Teen Dental Plan. Access to primary care dentistry in the private sector, where the majority of dental services are provided, remains a critical issue. Under the current system of dentistry, it cannot be assumed that the practice of dentistry represents a prioritised approach to combat disease patterns based on scientific evidence in primary health and prevention. Drawing on data in relation to these two programs, the present study highlights issues impacting dental service provision. This includes issues such as access and affordability to dental care, sustainability of policy and its unintended consequences, private practice pressures and the impact of remuneration on treatment. This paper argues that without structural reform there will continue to be barriers in implementing policies capable of improving oral health.

    Pediatric dentistry has enjoyed growing popularity in recent years, yet there remains a need for leadership in academe, research, and public health. In November 2008, the first Maternal and Child Health Bureau-sponsored regional Leadership in Pediatric Dentistry convocation was held at the Columbia University College of Dental Medicine. Seventy-two pediatric dentistry trainees from thirteen programs in the New York City area participated in interactive presentations and exercises. Of the sixty- seven participants who completed a pre-event survey, 93 percent stated they would likely or very likely pursue careers that involved, at least in part, private practice, 55 percent in care of children in Medicaid, 51 percent academics, 36 percent dental public health, and 12 percent research. Barriers related to finances, competence, or work environment/location were perceived by 83 percent for careers involving research, 73 percent for dental public health, 66 percent for providing care to children in Medicaid, 46 percent for academics, and 9 percent for private practice. Results of a pair of pre-event and post-event surveys completed by sixty-three attendees showed no change in reported likelihood to pursue a career alternative except for an increase in the likelihood of working in a practice that accepts Medicaid. The challenge before dental educators is to provide consistent and meaningful opportunities throughout training that encourage residents to consider all career options and to discover how their individual interests mesh with their clinical learning.

    The aim of this study was the fabrication and evaluation of a novel bioactive and bactericidal material, which could have applications in dentistry by supporting tissue regeneration and killing oral bacteria. Our hypothesis was that a new scaffold for pulp-dentin tissue engineering with enhanced antibacterial activity could be obtained by associating extracellular matrix derived from porcine bladder with an antibacterial bioactive glass. Our study combines in vitro approaches and ectopic implantation in scid mice. The novel material was fabricated by incorporating a sol-gel derived silver (Ag)-doped bioactive glass (BG) in a natural extracellular matrix (ECM) hydrogel in ratio 1:1 in weight % (Ag-BG/ECM). The biological properties of the Ag-BG/ECM were evaluated in culture with dental pulp stem cells (DPSCs). In particular, cell proliferation, cell apoptosis, stem cells markers profile, and cell differentiation potential were studied. Furthermore, the antibacterial activity against Streptococcus mutans and Lactobacillus casei was measured. Moreover, the capability of the material to enhance pulp/dentin regeneration in vivo was also evaluated. Our data show that Ag-BG/ECM significantly enhances DPSCs' proliferation, it does not affect cell morphology and stem cells markers profile, protects cells from apoptosis, and enhances in vitro cell differentiation and mineralisation potential as well as in vivo dentin formation. Furthermore, Ag-BG/ECM strongly inhibits S. mutans and L. casei growth suggesting that the new material has also anti-bacterial properties. This study provides foundation for future clinical applications in dentistry. It could potentially advance the currently available options of dental regenerative materials.

    The authorization of departments of community dentistry and public health in the nation's dental schools is a relatively recent innovation in dental education. Such a department was established at the University of Southern California School of Dentistry in 1966, as part of the School of Medicine's effort to share responsibility in providing both access and availability of health services in inner-city Los Angeles, California. Dentistry was included in the protocol submitted to the US Office of Economic Opportunity to build a neighborhood health center in Watts, operated under the joint jurisdiction of the medical and dental schools. The dental division of the health center was designated a satellite of the community dentistry department. The department envisioned future changes during the revolutionary 1960s when all aspects of the nation were experiencing upheaval as traditional concepts were challenged by new attitudes. The nation's leaders in government and education as well as in the health professions were stimulated by scientific and technologic discoveries. Dentistry had come of age, having gained the respect of other health-care disciplines. It was a time of expanded exploration of means toward a healthier populace and a more sensitive ethical provider of health care. In one decade, the USC community dentistry department accomplished a major shift in attitude about the specialty from one of pervasive opposition and antipathy to that of acceptance and even enthusiasm. The department became competitive with similar units nationwide in educating dental students and practitioners to fulfill their responsibilities at the highest level of proficiency and to be true to the trust bestowed on them by the public. In pursuit of these goals, the department reflected credit on dentistry and the University of Southern California.

    The authorization of departments of community dentistry and public health in the nation's dental schools is a relatively recent innovation in dental education. Such a department was established at the University of Southern California School of Dentistry in 1966, as part of the School of Medicine's effort to share responsibility in providing both access and availability of health services in inner-city Los Angeles, California. Dentistry was included in the protocol submitted to the US Office of Economic Opportunity to build a neighborhood health center in Watts, operated under the joint jurisdiction of the medical and dental schools. The dental division of the health center was designated a satellite of the community dentistry department. The department envisioned future changes during the revolutionary 1960s when all aspects of the nation were experiencing upheaval as traditional concepts were challenged by new attitudes. The nation's leaders in government and education as well as in the health professions were stimulated by scientific and technologic discoveries. Dentistry had come of age, having gained the respect of other health-care disciplines. It was a time of expanded exploration of means toward a healthier populace and a more sensitive ethical provider of health care. In one decade, the USC community dentistry department accomplished a major shift in attitude about the specialty from one of pervasive opposition and antipathy to that of acceptance and even enthusiasm. The department became competitive with similar units nationwide in educating dental students and practitioners to fulfill their responsibilities at the highest level of proficiency and to be true to the trust bestowed on them by the public. In pursuit of these goals, the department reflected credit on dentistry and the University of Southern California.

    The validity and reliability of a newly-developed objective structured clinical examination for 4th year dental students (OSCE(D)) were estimated by a range of quantitative and qualitative methods. The OSCE(D) consisted of 17 stations in conservation, periodontology and prosthetics. A blueprint was used to match the OSCE stations to clinical subject areas and to 7 skill clusters of clinical competence. Repeat measures of skills were undertaken in the OSCE(D) to maximise its validity and reliability. The primary purposes of the OSCE(D) were to assess clinical competence and to provide feedback to students. The results indicate that the OSCE(D) was intrinsically valid and a better predictor of performance in the final examination than either a concurrent 4th-year examination or Advanced-level university entry grades. The OSCE(D) scored relatively highly on internal consistency (Cronbach's alpha = 0.68). Intra-domain and inter-domain correlations were high and inter-examiner reliability was relatively high (eta 2 coefficients ranged from 0.00 to 0.10). There were no significant differences between performances in the morning and afternoon sessions of the examination so reproducibility is assumed to be high. Some improvement in individual stations and in inter-examiner reliability are required. A set of recommendations based on the experience of designing and testing a dental OSCE are provided.

    Context Most child population is able to undergo dental treatment in the conventional setting. However, some children fail to cope with in-office conscious state and cannot respond to usual management modalities. This review aims to discuss the topic further. Evidence Acquisition A computerized search in databases PubMed, MEDLINE, EMBASE, Google Scholar and Google were performed using dental general anesthesia related keywords. Original and review English-written articles that were limited to child population were retrieved without any limitation of publication date. The suitable papers were selected and carefully studied. A data form designed by author was used to write relevant findings. Results Preoperative oral examination and comprehensive evaluation of treatment needs is only possible after clinical and radiographic oral examination. Effective collaboration in dental GA team should be made to minimize psychological trauma of children who undergo dental GA. Before conducting comprehensive dental treatment under GA, the general health of the child and the success rate of procedures provided needs to be accurately evaluated. It is noteworthy that determination of the optimal timing for GA dental operation is of great importance. Providing safety with pediatric dental rehabilitation under GA is critical. Conclusions Besides criteria for case selection of dental GA, some degree of dental practitioner’s judgment is required to make decision. Pre- and post-operative instructions to parents or caregiver decrease the risk of complications. However, trained resuscitation providers, careful monitoring and advanced equipment minimize adverse outcomes. PMID:27307962

    The aim of this study was to investigate whether advanced simulation parameters, such as simulation exam scores, number of student self-evaluations, time to complete the simulation, and time to complete self-evaluations, served as predictors of dental students' preclinical performance. Students from three consecutive classes (n=282) at one U.S. dental school completed advanced simulation training and exams within the first four months of their dental curriculum. The students then completed conventional preclinical instruction and exams in operative dentistry (OD) and fixed prosthodontics (FP) courses, taken during the first and second years of dental school, respectively. Two advanced simulation exam scores (ASES1 and ASES2) were tested as predictors of performance in the two preclinical courses based on final course grades. ASES1 and ASES2 were found to be predictors of OD and FP preclinical course grades. Other advanced simulation parameters were not significantly related to grades in the preclinical courses. These results highlight the value of an early psychomotor skills assessment in dentistry. Advanced simulation scores may allow early intervention in students' learning process and assist in efficient allocation of resources such as faculty coverage and tutor assignment.

    Introduction Eco-friendly or green dentistry can be a reality by effectively designing dental clinics and using more eco-friendly materials in the clinical practice. Aim To determine the awareness of eco-friendly dentistry among dental faculty and students in preparation for future implementation. Materials and Methods Assessment of knowledge regarding eco-friendly dentistry was done using an 18 item self-administered questionnaire among 160 participants. After baseline data collection, the intervention was done by educating participants with a power point presentation. The post-intervention data was then collected for analysis. Statistical analysis was done using Wilcoxon’s signed rank test and one-way ANOVA. Results The educational intervention increased the knowledge about eco-friendly dentistry confirming the importance of continuing education. There was a statistically significant gain in knowledge among the participants after the presentation. The gain was highest for department of Preventive Dental Sciences (PDS) followed by Substitute Dental Sciences (SDS), No specialty, Maxillofacial Dental Sciences (MDS), and Restorative Dental Sciences (RDS) respectively. (F=5.5091, p<0.05). Conclusion Lack of knowledge of green dentistry amongst the dental fraternity is highly prevailing. The same can be substantiated with effective training in the respective fields if channelized through the curriculum in an educational set-up. PMID:27891464

    SUMMARY Rubber dam use during operative dentistry procedures has been quantified based on questionnaires completed by dentists. However, to our knowledge there are no reports based on use during actual clinical procedures other than in dental materials studies, and none based on routine care. Our objectives were to: (1) quantify how commonly the rubber dam is used during operative dentistry procedures; (2) test the hypothesis that certain dentist-, restoration- and patient-level factors are associated with its use. A total of 229 dentist practitioner-investigators in “The Dental Practice-Based Research Network (DPBRN)” participated. DPBRN comprises five regions: Alabama/Mississippi, Florida/Georgia, Minnesota, Permanente Dental Associates, and Scandinavia. Practitioner-investigators collected data on 9,890 consecutive restorations done in previously-unrestored tooth surfaces from 5,810 patients. Most dentists (63%) did not use a rubber dam for any restoration in the study. A rubber dam was used for only 12% of restorations, 83% of which were used in one DPBRN region. With region accounted for, no other dentist characteristics were significant. A multi-level multiple logistic regression of rubber dam use was done with restoration- and patient-level variables modeled simultaneously. In this multi-variable context, these restoration-level characteristics were statistically significant: tooth-arch type, restoration classification, and reason for placing the restoration. These patient-level characteristics were statistically significant: ethnicity, dental insurance, and age. These results, obtained from actual clinical procedures rather than questionnaires, document a low prevalence of usage of rubber dam during operative dentistry procedures. Usage varied with certain dentist-, restoration-, and patient-level characteristics. PMID:20945739

    In 2008, Texas A&M University Baylor College of Dentistry launched a comprehensive four-year curriculum in evidence-based dentistry (EBD) along with a series of faculty development initiatives to create an EBD culture. The aim of this study was to determine the institution's success in achieving this goal. The assessment tool used was the PEAK instrument, which measures respondents’ EBD Practices, Experience, Attitudes, and Knowledge. Two EBD-trained classes of students and one class untrained in EBD (approximately 100 students in each class) were assessed annually. The faculty were assessed before and after completion of the initiative. Nearly all students responded, with samples ranging from 87 to 102; the faculty response rates were 53% (62/117) in 2009 and 66% in 2013 (81/123). In the results, the trained students scored significantly higher in knowledge than the untrained students at each of the first three PEAK administrations (p≤0.001). Regarding confidence in appraising a research report, the first trained group significantly gained in appropriate use of statistical tests (p<0.001), while the second trained group significantly gained in this aspect and five others (p≤0.032). At the final PEAK administration, the second trained group agreed more than the untrained group that EBD was important for the practice of dentistry (p<0.001). Faculty comfort level with reading peer-reviewed articles increased significantly from 2009 to 2013 (p=0.039). Faculty members who participated in the summer EBD Fundamentals course (n=28) had significantly higher EBD knowledge scores than those who did not participate (p=0.013), and their EBD attitudes and practices were more positive (p<0.05). Students and faculty trained in EBD were more knowledgeable and exhibited more positive attitudes, supporting a conclusion that the college has made substantial progress towards achieving an EBD culture.

    Economic evaluation (EE) studies have been undertaken in dentistry since the late 20th century because economic data provide additional information to policy makers to develop guidelines and set future direction for oral health services. The objectives of this study were to assess the methodological quality of EEs in oral health. Electronic searching of Ovid MEDLINE, the Cochrane Library, and the NHS Economic Evaluation Database from 1975 to 2013 were undertaken to identify publications that include costs and outcomes in dentistry. Relevant reference lists were also searched for additional studies. Studies were retrieved and reviewed independently for inclusion by 3 authors. Furthermore, to appraise the EE methods, 1 author applied the Drummond 10-item (13-criteria) checklist tool to each study. Of the 114 publications identified, 79 studies were considered full EE and 35 partial. Twenty-eight studies (30%) were published between the years 2011 and 2013. Sixty-four (53%) studies focused on dental caries prevention or treatment. Median appraisal scores calculated for full and partial EE studies were 11 and 9 out of 13, respectively. Quality assessment scores showed that the quality of partial EE studies published after 2000 significantly improved (P = 0.02) compared to those published before 2000. Significant quality improvement was not found in full EE studies. Common methodological limitations were identified: absence of sensitivity analysis, discounting, and insufficient information on how costs and outcomes were measured and valued. EE studies in dentistry increased over the last 40 y in both quantity and quality, but a number of publications failed to satisfy some components of standard EE research methods, such as sensitivity analysis and discounting.

    Interest in the use of engineered nanomaterials (ENMs) as either nanomedicines or dental materials/devices in clinical dentistry is growing. This review aims to detail the ultrafine structure, chemical composition, and reactivity of dental tissues in the context of interactions with ENMs, including the saliva, pellicle layer, and oral biofilm; then describes the applications of ENMs in dentistry in context with beneficial clinical outcomes versus potential risks. The flow rate and quality of saliva are likely to influence the behavior of ENMs in the oral cavity, but how the protein corona formed on the ENMs will alter bioavailability, or interact with the structure and proteins of the pellicle layer, as well as microbes in the biofilm, remains unclear. The tooth enamel is a dense crystalline structure that is likely to act as a barrier to ENM penetration, but underlying dentinal tubules are not. Consequently, ENMs may be used to strengthen dentine or regenerate pulp tissue. ENMs have dental applications as antibacterials for infection control, as nanofillers to improve the mechanical and bioactive properties of restoration materials, and as novel coatings on dental implants. Dentifrices and some related personal care products are already available for oral health applications. Overall, the clinical benefits generally outweigh the hazards of using ENMs in the oral cavity, and the latter should not prevent the responsible innovation of nanotechnology in dentistry. However, the clinical safety regulations for dental materials have not been specifically updated for ENMs, and some guidance on occupational health for practitioners is also needed. Knowledge gaps for future research include the formation of protein corona in the oral cavity, ENM diffusion through clinically relevant biofilms, and mechanistic investigations on how ENMs strengthen the tooth structure.

    The study objective was to assess predoctoral dental students' experience with a caries risk assessment computer program in the pediatric dentistry clinic at Marquette University School of Dentistry. In 2005, spring semester sophomore dental students (class of 2008) were introduced to the caries risk assessment computer program "Cariogram." The students received a fifty-minute lecture on caries risk assessment and a demonstration on how to use Cariogram in the clinic. After two years of clinical exposure to Cariogram, sixty-six out of eighty senior dental students completed an anonymous eleven-item questionnaire on their experience with the tool. Each item on the questionnaire was scored on a five-point Likert scale with the exception of two questions. Full- and part-time faculty members in the pediatric dentistry clinic were involved in teaching and supervising students in the use of Cariogram for caries risk assessment after their training and calibration. Forty-five percent of the students who participated in the study agreed that Cariogram was easy to understand, and 18 percent disagreed. Thirty-six percent felt that it was easy to apply, and 25 percent reported that it was useful in determining caries preventive procedures. The students reported that 60 percent of full-time and 33 percent of part-time faculty were knowledgeable about Cariogram use. A majority of the students felt that Cariogram was not easy to understand, and eighty-two percent of them reported that they would not be using Cariogram in their private offices. Future studies should explore reasons why students do not feel inclined to use Cariogram as a caries risk assessment tool in their private practices even after being exposed to the tool in dental school.

    Interprofessional education (IPE) has received increasingly more attention over recent years. The objectives of this study were to assess 1) how nursing students' considerations concerning their own oral health and oral health-related knowledge changed from before to after experiencing IPE; 2) how nursing students', dental students', and pediatric dentistry residents' IPE-related attitudes and Readiness for Interprofessional Learning Scale (RIPLS) scores changed after experiencing an IPE rotation; and 3) how these groups' attitudes and RIPLS scores were related. Data were collected from three groups who participated in an IPE rotation: thirty-eight of forty third-year dental students (95 percent response rate), all thirty-three nursing students (100 percent), and all six pediatric dentistry residents (100 percent) prior to the rotation, and 100 percent of each group after the rotation. As a control group, data were also collected at the beginning of the winter term from first-year dental students (104 out of 105; 99 percent response rate) and second-year dental students (102 out of 116; 88 percent); the same groups were surveyed at the end of term, with response rates of 98 percent for first-year students and 89 percent for second-year students. After the rotation, the nursing students' tooth brushing frequency increased, and their comfort level with dental visits and oral health-related knowledge improved. The dental students rated the importance of nurses' having oral health-related knowledge and skills lower than did the nursing students and pediatric dentistry residents. The groups' RIPLS scores correlated with these importance ratings. Overall, while the nursing students showed positive responses to IPE, the dental students' attitudes and RIPLS scores did not change as a result of the IPE experience. Future research should explore the conditions under which dental students are impacted by IPE.

  6. The need for leadership and vision in dentistry. A personal view.

    PubMed

    Holt, Vernon P

    2008-07-01

    This paper considers how dentistry has developed in the United Kingdom (UK) over the last 60 years and concludes that dentists have failed to be proactive and to shape the systems for the delivery of an optimal level of care to the population. It suggests that there is a need for far better leadership and for dentists, as individuals and as a profession, to rediscover the sense of vision that they once had and to shape their destinies, rather than accepting the current situation. The author goes on to explain how this might be done. Since the inception of the National Health Service (NHS), the dental profession in the UK has, to a large extent, been dominated by the politics of the NHS, by changing fee structures and contracts, by reports from the Review Body on Doctors' and Dentists' Remuneration (DDRB), and by strategies adopted by successive governments, especially during the last two decades. These strategies have resulted in cohorts of disillusioned dental practitioners reducing their commitment to, or opting out of, NHS contracts and committing themselves, to a greater or lesser extent, to private practice. It is now over three years since, for the first time, the proportion of dentistry provided under private contact in the UK, as measured by gross fees, exceeded that provided under NHS contract. The profession has shown a remarkable lack of imagination in organising itself to provide the best kind of care for patients. Instead of being proactive and visionary, it has allowed itself to become a political football. This has led to the progressive deskilling of many practitioners, and a manifest failure to secure the long-term oral health of patients. This paper considers how the situation could be improved and looks at four aspects, which are: 1. 21st century dentistry: state of the art versus reality? The contrast between what is clinically possible and what the profession currently delivers. 2. What are we here for? The need for a new vision for dentistry

    In this article, we look at the philosophy of customer focus and value, and how dental practices can produce and deliver high customer value and satisfaction, to retain as well as attract their customers-the patients. Total quality concepts will also be discussed in the context of their relationship with marketing activities. In all cases, where 'customer' is referenced, this means 'patient' in the context of a dentistry, since patients are the customers, their requirements must be considered in targeting the marketing of a dental practice.

    2006-04-01

    There are numerous CAD/CAM technologies available today for the production of highly aesthetic restorations with strength and precision. Laboratory-based CAD/CAM systems typically require the patient to receive a provisional restoration and then return to the dental office for a second visit for placement of the definitive restoration upon receipt from the laboratory. Chairside systems, as described in the following case presentation, allow excellent benefits to be achieved in one patient visit. Thus, this case presentation describes the sequences associated with single-visit, in-office CAD/CAM quadrant dentistry.

  9. Examining whether dental therapists constitute a disruptive innovation in US dentistry.

    2011-10-01

    Dental therapists-midlevel dental providers who are roughly analogous to nurse practitioners in medicine-might constitute a disruptive innovation within US dentistry. Proponents tend to claim that dental therapists will provide more equitable access to dental care; opponents tend to view them from a perspective that focuses on retaining the current attributes of the dental profession. Therapists display traits similar to those of disruptive innovations: their attributes are different from dentists', they may not initially be valued by current dental patients, they may appeal to current dental underutilizers, and they may transform the dental delivery system. Whether dental therapists constitute a disruptive innovation will only be determined retrospectively.

    The article touches upon the technology of basalt fiber manufacturing and prospects of its use in dental practice. Two kinds of construction using basalt fiber have been proposed. The first one is a splinting construction for mobile teeth and the second one is the reinforced base for removable plate-denture. The work presents the results of the investigation of physical and mechanical properties of the constructions based on basalt fiber. It also describes the aspects of biomechanical modeling of such constructions in the ANSYS software package. The results of the investigation have proved that applying constructions using basalt fiber is highly promising for prosthetic dentistry practice.

    The study of anatomy is important to accomplish any kind of surgical and medical procedure and to understand the physiology and diseases of animals. It is no different in veterinary dentistry. The study of oral anatomy helps the veterinarian to accomplish any kind of surgical procedure more quickly and with less damage to tissues, especially in cases of major oral surgery. In fact, under-standing the anatomy is easier when this knowledge is acquired directly, with surgical application. This article describes the essentials of the oral anatomy of the dog and cat, correlating this knowledge with the dental procedures to be used by veterinarians as a guide.

    An increasing proportion of the population is medically compromised. Dental and medical staff need to communicate and cooperate to afford these patients the best possible health care. In this study, the attitude towards and awareness of medical problems were examined in final-year predoctoral (undergraduate) dental and in final-year medical students. The results revealed that most dental students felt their knowledge of and training in medical problems in dentistry to be moderate to good. In contrast, most medical students thought both their knowledge and training in medical problems in dentistry to be only poor to moderate. Dental students rated the importance of medical problems in dentistry higher than did medical students.

    Over the past decade, the dental field has benefited from recent findings in stem cell biology and tissue engineering that led to the elaboration of novel ideas and concepts for the regeneration of dental tissues or entire new teeth. In particular, stem cell-based regenerative approaches are extremely promising since they aim at the full restoration of lost or damaged tissues, ensuring thus their functionality. These therapeutic approaches are already applied with success in clinics for the regeneration of other organs and consist of manipulation of stem cells and their administration to patients. Stem cells have the potential to self-renew and to give rise to a variety of cell types that ensure tissue repair and regeneration throughout life. During the last decades, several adult stem cell populations have been isolated from dental and periodontal tissues, characterized, and tested for their potential applications in regenerative dentistry. Here we briefly present the various stem cell-based treatment approaches and strategies that could be translated in dental practice and revolutionize dentistry. PMID:27648076

    One of the most important figures in the development of the dental profession was Solyman Brown, in whose home the leading dentists of his day met and organized the first national dental organization in the world as well as the first dental journal in the world. He was named the first secretary of the organization and served, for two years, as the first editor of the journal. A true Renaissance man, Brown was also a consummate, and widely published, poet, and his epic poem, Dentologia, was hailed by the critics of his day as a literary masterpiece, earning him the sobriquet, "Poet Laureate of Dentistry." Recently Solyman Brown's great-great grandson, cleaning out an attic, discovered a trunk full of material relating to Brown's life - his daughters' memoirs, many of his letters and other of his writings, and many of his unpublished poetical works. This author was fortunate to be able to study all this material, and the poems published herein give a much fuller and rounded picture of this monumental figure in American, and world, dentistry.

    In recent years there have been an increasing number of in vitro and in vivo studies that show positive results regarding antimicrobial photodynamic therapy (aPDT) used in dentistry. These include applications in periodontics, endodontics, and mucosal infections caused by bacteria present as biofilms. Antimicrobial photodynamic therapy is a therapy based on the combination of a non-toxic photosensitizer (PS) and appropriate wavelength visible light, which in the presence of oxygen is activated to produce reactive oxygen species (ROS). ROS induce a series of photochemical and biological events that cause irreversible damage leading to the death of microorganisms. Many light-absorbing dyes have been mentioned as potential PS for aPDT and different wavelengths have been tested. However, there is no consensus on a standard protocol yet. Thus, the goal of this review was to summarize the results of research on aPDT in dentistry using the PubMed database focusing on recent studies of the effectiveness aPDT in decreasing microorganisms and microbial biofilms, and also to describe aPDT effects, mechanisms of action and applications.

    Educational technologies such as video cases can improve health professions student learning outcomes, but few studies in dentistry have evaluated video-based technologies. The goal of this study was to compare outcomes associated with video and paper cases used in an introductory public health dentistry course. This was a retrospective cohort study with a historical control group. Based on dual coding theory, the authors tested the hypotheses that dental students who received a video case (n=37) would report better affective, cognitive, and overall learning outcomes than students who received a paper case (n=75). One-way ANOVA was used to test the hypotheses across ten cognitive, two affective, and one general assessment measures (α=0.05). Students in the video group reported a significantly higher overall mean effectiveness score than students in the paper group (4.2 and 3.3, respectively; p<0.001). Video cases were also associated with significantly higher mean scores across the remaining twelve measures and were effective in helping students achieve cognitive (e.g., facilitating good discussions, identifying public health problems, realizing how health disparities might impact their future role as dentists) and affective (e.g., empathizing with vulnerable individuals, appreciating how health disparities impact real people) goals. Compared to paper cases, video cases significantly improved cognitive, affective, and overall learning outcomes for dental students.

    Meeting the oral health care needs of the growing population of people with special health care needs (SHCN) starts with dental students' acquisition of sound knowledge and development of clinical competence at the predoctoral level. The aim of this study was to review the level of undergraduate education in Special Needs Dentistry (SND) in Malaysian and Australian dental schools. The deans of all six Malaysian public dental schools and eight of nine Australian dental schools participated in a postal survey on current undergraduate didactic and clinical training in SND at their institutions. The results showed the number of dental schools in Malaysia with teaching in SND as a specific discipline was relatively low compared to that of Australia. However, a high percentage of Malaysian and Australian dental schools reported incorporating teaching of SND into pediatric dentistry (83.3 percent vs. 75 percent), oral medicine/oral pathology (66.7 percent vs. 75 percent), and oral surgery (66.7 percent vs. 25 percent). Most respondents said their school delivered SND clinical training in dental school clinics, hospital-based settings, and residential aged care facilities. Respondents in both countries viewed lack of faculty expertise as the greatest barrier to providing SND education. The study provides valuable information that can direct SND curriculum development in the two countries.

    Industry-supported clinical trials may present better outcomes than those supported by other sources. The aim of this paper was to assess whether systematic reviews (SRs) published in periodontology and implant dentistry report and discuss the influence of funding sources on study results. Two reviewers conducted a comprehensive search in PubMed and the Cochrane Database of Systematic Reviews independently and in duplicate to identify SRs published up to 11 November 2012. Speciality dental journals and the reference lists of included SRs were also scrutinised. Information on the reporting and discussion of funding sources of primary studies included in the SRs was extracted independently and in duplicate. Any disagreement regarding SR selection or data extraction was discussed until consensus was achieved. Of 146 SRs included in the assessment, only 45 (31%) reported the funding sources of primary studies. Fourteen (10%) SRs discussed the potential influence of funding sources on study results, that is, sponsorship bias. Funding sources are inadequately reported and discussed in SRs in periodontology and implant dentistry. Assessment, reporting, and critical appraisal of potential sponsorship bias of meta-analytic estimates are paramount to provide proper guidance for clinical treatments.

  20. Induced Pluripotent Stem (iPS) Cells in Dentistry: A Review

    iPS cells are derived from somatic cells via transduction and expression of selective transcription factors. Both viral-integrating (like retroviral) and non-integrating (like, mRNA or protein-based) techniques are available for the production of iPS cells. In the field of dentistry, iPS cells have been derived from stem cells of apical papilla, dental pulp stem cells, and stem cells from exfoliated deciduous teeth, gingival and periodontal ligament fibroblasts, and buccal mucosa fibroblasts. iPS cells have the potential to differentiate into all derivatives of the 3 primary germ layers i.e. ectoderm, endoderm, and mesoderm. They are autogeneically accessible, and can produce patient-specific or disease-specific cell lines without the issue of ethical controversy. They have been successfully tested to produce mesenchymal stem cells-like cells, neural crest-like cells, ameloblasts-like cells, odontoblasts-like cells, and osteoprogenitor cells. These cells can aid in regeneration of periodontal ligament, alveolar bone, cementum, dentin-pulp complex, as well as possible Biotooth formation. However certain key issues like, epigenetic memory of iPS cells, viral-transduction, tumorgenesis and teratoma formation need to be overcome, before they can be successfully used in clinical practice. The article discusses the sources, pros and cons, and current applications of iPS cells in dentistry with an emphasis on encountered challenges and their solutions. PMID:27572712
