    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

    Although human mouth benefits from remarkable mechanical properties, it is very susceptible to traumatic damages, exposure to microbial attacks, and congenital maladies. Since the human dentition plays a crucial role in mastication, phonation and esthetics, finding promising and more efficient strategies to reestablish its functionality in the event of disruption has been important. Dating back to antiquity, conventional dentistry has been offering evacuation, restoration, and replacement of the diseased dental tissue. However, due to the limited ability and short lifespan of traditional restorative solutions, scientists have taken advantage of current advancements in medicine to create better solutions for the oral health field and have coined it "regenerative dentistry." This new field takes advantage of the recent innovations in stem cell research, cellular and molecular biology, tissue engineering, and materials science etc. In this review, the recently known resources and approaches used for regeneration of dental and oral tissues were evaluated using the databases of Scopus and Web of Science. Scientists have used a wide range of biomaterials and scaffolds (artificial and natural), genes (with viral and non-viral vectors), stem cells (isolated from deciduous teeth, dental pulp, periodontal ligament, adipose tissue, salivary glands, and dental follicle) and growth factors (used for stimulating cell differentiation) in order to apply tissue engineering approaches to dentistry. Although they have been successful in preclinical and clinical partial regeneration of dental tissues, whole-tooth engineering still seems to be far-fetched, unless certain shortcomings are addressed.

    Although there are a considerable number of published papers on the role of laser treatment in dentistry, a critical review shows that laser technology is used only by specialists in a small therapeutic field. Most lasers are heat-producing devices converting electromagnetic energy into thermal energy. These lasers find uses in oral surgery for cutting or coagulating soft tissues or in the welding of dental prostheses. More recently, new types of lasers have offered non-thermal modes of tissue interaction, called photoablation, photodisruption and photochemical effects. Basic and clinical research is being carried out into the application of these devices in dentistry. However, much development will be required before lasers can replace conventional surgical methods for treating oral cancer or indeed replace the conventional bur for excavating carious lesions.

    In this study, 491 dental students at one dental school in the United States and one in Bulgaria were surveyed to assess their perceptions about the mission of dental schools to advance global dentistry and philanthropy. The study included questions about prior involvement in charitable dental missions. Many respondents felt that their dental school does not advance global dentistry nor adequately teaches students the virtues of philanthropy and volunteerism. The majority agreed, however, that dental schools have a moral obligation to raise the level of oral health care worldwide and help underserved communities access basic dental care. They reported that an opportunity to spend a semester at a foreign dental school would enhance their dental education in ways that are not presently fulfilled; help them better understand cultural diversity; and teach them about philanthropy and volunteerism. In their opinion, international exchange programs that provide clinical rotations and field experiences in economically challenged and underserved areas of the world would a) foster the global advancement of dentistry; b) promote an appreciation for cultural diversity and socioeconomic disparity in the communities that graduates will be serving; and c) teach students the virtues of philanthropy and volunteerism. This study may contribute to understanding factors affecting student involvement in programs to advance global dentistry.

    The RENO (Reactor Experiment for Neutrino Oscillation) experiment is under construction to measure the smallest neutrino mixing angle θ13 using anti-neutrinos emitted from the Yonggwang nuclear power plant in Korea. The experiment is planning to start data-taking in early 2011 with two identical 16-ton Gadolinium loaded liquid scintillator detectors located near and far from the center of the reactor array. The estimated systematic uncertainty associated with the measurement is less than 0.6%. Based on three years of data, the expected statistical error is about 0.3% and it would be sensitive to measure the neutrino mixing angle in the range, sin2(2θ13)> 0.02. In this talk, the overview and status of RENO experiment are described.

    2008-03-01

    The oral health of children became a more prominent concern with the U.S. surgeon general's report on oral health in America in 2000. The purpose of our study was 1) to assess General Practice Residency (GPR) and Advanced Education in General Dentistry (AEGD) (here jointly referred to as advanced general dentistry [AGD] programs) directors' current behaviors with regard to pediatric training of residents and 2) to assess their attitudes about which components of pediatric oral health training should be included in AGD programs. A twenty-one item survey was mailed to all GPR and AEGD programs accessed through the American Dental Association website. Seventy percent of directors (N=187) completed and returned the survey. Responses indicated that AGD residents receive adequate clinical exposure to pediatric patients and provide much-needed services to uninsured, underinsured, and underserved people. Although clinical training in pediatric treatment was high, didactic hours focused on pediatric treatment did not seem commensurate with clinical activity. Program directors indicated strong attitudinal support for teaching residents many components of pediatric oral health care, although most directors have concerns over increasing didactic hours spent on pediatric oral health due to already crowded curricula. Approximately 88 percent of directors said that they would implement a pediatric oral health module in their curricula if they had access to one.

    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.

    2015-11-01

    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.

    Columbia University College of Dental Medicine, in partnership with the Harlem United Community AIDS Center, has developed a service-learning (SL) program for use in the training of Advanced Education in General Dentistry (AEGD) residents. This article presents basic tenets of SL, their applicability for dentistry, and our experience implementing SL in care of people living with HIV/AIDS. It proposes that social-behavioral theory, when incorporated into the basic components of SL, can play a useful role in resolving a number of challenges inherent in competency-based training programs. Although the article provides examples of how a particular theory, the Theory of Planned Behavior, might be applied in the SL context, opportunities for the application of other social-behavioral theories potentially exist.

  8. 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

    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

    The RENO Model, first published during 2004, described a science-based framework of responsible gambling principles for a range of industry operators, health service providers, community and consumer groups, and governments. These strategic principles serve as a guide for the adoption and implementation of responsible gambling and harm-minimization initiatives. This article extends the RENO Model core principles by describing how to apply these strategies to clinical practice. This discussion examines the central tenets of the model and includes a review of (a) the ethical principles that should guide the development, implementation, and practice of RENO Model responsible gambling activities; (b) a brief consideration of the various perspectives that influence the treatment of gambling-related problems; and (c) a discussion of key applied elements of responsible gambling programs. This article advances the argument that, to maximize positive outcomes and to avoid unintended harms, clinicians should apply science-based principles to rigorously evaluate the efficacy and impact of their clinical practice activities.

    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. PMID:22639498

    2008-01-01

    The real definition of restorative dentistry is found in the heart and hands of each individual restorative dentist. His or her training, continuing dental education, mentors, needs (financial and emotional), and style of practice all help to develop a philosophy of dental practice that affects daily restorative decisions. Depending on the factors described above, the decision to repair a tooth or change the environment and restore the tooth to a different shape, size, or color also may change. In recent years, patients' esthetic desires have become more of a factor than they were in previous decades. There are no exact written-tn-stone definitions of restorative dentistry, since the answers are operator-dependent and can vary. This column is meant to be food for thought and perhaps inspire discussion when dentists assemble for meetings or study clubs with the goal of delivering longer-lasting dentistry through a restorative dental practice.

    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.

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.

    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.

  8. New trends in prosthetic dentistry.

    PubMed

    Hubálková, H; Linetskiy, I

    2006-01-01

    Prosthetic dentistry is one of the fundamental pillars of dentistry. Even though it is highly specialized in replacement of missing teeth and adjacent soft and hard oral tissues, the cooperation with other branches of dentistry is very important. It usually provides final stages of rehabilitation of the whole maxillofacial system. The loss of several teeth doesn't have to be an immediate threat to the function of the whole dentition, but it can initiate serious problems related to the whole orofacial region, psychics and the wellbeing of the patient. From this point of view prosthetic dentistry is a valuable tool with high therapeutical and preventive character. Modern prosthetics offers classical solutions with simple fixed and removable dentures, and advanced solutions with dental implants support for rehabilitation of dental defects. Final quality and prognosis of prosthetic treatment depends both on materials and technologies used and on the patients' motivation and dental care. Superior esthetical demands and biocompatibility issues drive dental manufacturers to introduce new materials with defined properties. Nowadays the most sophisticated systems are based on ceramics, dental implants and CAD/CAM technologies.

  9. Biomaterials in Relation to Dentistry.

    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

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

  16. Advances in pediatric esthetic dentistry.

    PubMed

    Cannon, Mark L

    2003-08-01

    The introduction of low-shrinkage composite and no-rinse conditioners has created an opportunity for pediatric dentists to change their standard operative regimen. The low-shrink composite solves many of the problems that have discouraged clinicians from routinely providing posterior composites for their patients. The reduction in polymerization shrinkage decreases problems with contraction stresses, sensitivity, microleakage, recurrent caries, and negative pulpal sequelae. No-rinse conditioners simplify the process and shorten the time required for bonding procedures. Liquid polish reduces the tedious finishing previously required with resin-based composites. The combination of the easier bonding and more user-friendly composite could add a new operative technique to the pediatric dentist's armamentarium. A study of low-shrink, resin-based composite restorations was performed to determine the effectiveness of these new materials for pediatric dental practice. The restorations were placed in primary molars to allow for their retrieval when exfoliated. The preparation and restorative techniques were standardized to match a similar study that used the "open-sandwich" method. The modified US Public Health Service ranking was used to evaluate marginal integrity at 6-month intervals for the 40 restorations placed in primary molars as a pilot study. TESCERA ATL restorations and prostheses were also evaluated for clinical effectiveness.

    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 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. PMID:17589569

The recent advances in nanodentistry and innovations in oral health-related diagnostic, preventive, and therapeutic methods required to maintain and obtain perfect oral health, have been discussed. The recent advances in nanotechnology could hold promise in bringing a paradigm shift in dental field. Although there are numerous complex therapies being developed to treat many diseases, their clinical use requires careful consideration of the expense of synthesis and implementation.

This plant is proved to be non allergic and very good in building up the immune system. Aloe vera is gaining popularity in dentistry as it is completely natural and there is no side effects being reported with its use. This paper gives an overview of the uses of this miracle plant and its uses in dentistry.

  14. Corporate dentistry in 2032?

    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. PMID:23073159

    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. PMID:25828074

    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

  2. Planetary Boundary Layer Dynamics over Reno, Nevada in Summer

    2014-12-01

    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 successful practice of dentistry involves a good combination of technical skills and soft skills. Soft skills or communication skills are not taught extensively in dental schools and it can be challenging to learn and at times in treating dental patients. Guiding the child's behavior in the dental operatory is one of the preliminary steps to be taken by the pediatric dentist and one who can successfully modify the behavior can definitely pave the way for a life time comprehensive oral care. This article is an attempt to revisit a simple behavior guidance technique, reframing and explain the possible psychological perspectives behind it for better use in the clinical practice.

    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.

  7. Understanding wear in dentistry.

    PubMed

    Mair, L H

    1999-01-01

    Tooth wear is an increasing problem in dentistry. Traditionally, it has been divided into three categories: abrasion, attrition, and erosion. However, most clinical cases of tooth wear involve more than one of these processes. It is often easier to make a diagnosis by looking for the signs of the fundamental wear processes rather than trying to categorize the individual case. Wear can be caused by direct surface-to-surface wear, an intervening slurry, or a corrosive environment. Wear occurs during mastication, but also at other times, often at night. Although it may be possible to institute a preventive regimen, this will not always help the patient if his or her prime concern is esthetics. The same processes that cause tooth wear will cause wear to restorative materials. To diagnose and prevent wear, its processes must be understood.

    2015-01-01

    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.

    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.

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.

    Konopka, K; Goslinski, T

    2007-08-01

    Photodynamic therapy (PDT), also known as photoradiation therapy, phototherapy, or photochemotherapy, involves the use of a photoactive dye (photosensitizer) that is activated by exposure to light of a specific wavelength in the presence of oxygen. The transfer of energy from the activated photosensitizer to available oxygen results in the formation of toxic oxygen species, such as singlet oxygen and free radicals. These very reactive chemical species can damage proteins, lipids, nucleic acids, and other cellular components. Applications of PDT in dentistry are growing rapidly: the treatment of oral cancer, bacterial and fungal infection therapies, and the photodynamic diagnosis (PDD) of the malignant transformation of oral lesions. PDT has shown potential in the treatment of oral leukoplakia, oral lichen planus, and head and neck cancer. Photodynamic antimicrobial chemotherapy (PACT) has been efficacious in the treatment of bacterial, fungal, parasitic, and viral infections. The absence of genotoxic and mutagenic effects of PDT is an important factor for long-term safety during treatment. PDT also represents a novel therapeutic approach in the management of oral biofilms. Disruption of plaque structure has important consequences for homeostasis within the biofilm. Studies are now leading toward selective photosensitizers, since killing the entire flora leaves patients open to opportunistic infections. Dentists deal with oral infections on a regular basis. The oral cavity is especially suitable for PACT, because it is relatively accessible to illumination. PMID:17652195

    Due to a rapid increase of unemployment among dentists in many countries, the interest in advertising as a means of stimulating the demand for dental care is increasing. In some countries (i.e. USA, Canada, Finland and Holland) campaigns have been organized and the results have been published. In order to give as complete a picture as possible of all promotional activities in the field of dentistry, the member organizations of the FDI have been asked to answer the following questions: (1) Are individual dentists in your country allowed to solicit new patients by means of advertisements? (2) Do you, as an organization, have guidelines for your members in this respect? (3) Have there been any joint promotional activities by dentists in your country aimed at increasing the demand for dental care? (a) If so, in what form (e.g. advertisements, television or radio commercials)? (b) How much money was invested in such activities? (c) What were the results achieved? The results are presented. The effectiveness of specific methods used in stimulating the demand for dental care are analysed. Moreover, a comparison is made between studies on the attitudes of dentists toward advertising in Holland and the United States. PMID:3476465

  16. 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.

    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.

  18. 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.

    The speed at which advances are being made in science has catapulted nanotechnology from its theoretical foundations straight into the real world. There are now many examples of commercially available products demonstrating that, in given situations, the technology really does work and that its scope for further application is wide. Healthcare, along with society as a whole, is facing a major revolution in the wake of ongoing technological developments in the field of nanotechnology. Dentistry as an individual healthcare discipline is not exempt, having already been targeted directly with novel 'nano-materials' at the same time as indirectly enjoying the benefits of nano-related advances in the electronics industry through the ongoing computerization of the modern practice. This article examines current practical applications of nanotechnology alongside proposed applications in the future and aims to demonstrate that, as well as a good deal of science fiction, there is some tangible science fact emerging from this novel multi-disciplinary science.

    Since the early 80's, the use of laser has been introduced in the daily dental practice and the technological development has also provided over time to optimize its use. 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.

    Results from the pre-feasibility study of a geothermal district heating system for greater Reno and the pre-feasibility study of providing geothermal heat to casinos/hotels located in downtown Reno by connection to the proposed district heating system (DHS) are combined. Geothermal sources were selected from published data. Potential users were selected from aerial and city planning maps, and published building and demographic information. Energy consumption data from the electric and gas utility was matched with consumption information from surveys of representative buildings by category and climatic data. As an example, a written survey was mailed to the casino/hotels and two on-site visits were made. Retrofit methodology and cost were examined for the casino/hotels and representative buildings. Based on the pre-feasibility studies, a geothermal district heating system for Reno appears technically and economically feasible. Furthermore, additional economic savings are achieved when the Reno casinos/hotels are connected to the DHS. Steamboat Hot Springs and a geothermal area east of downtown are the most promising geothermal sources for the DHS. The City of Reno has a large yearly heat load with an average heating degree days per year of 6022/sup 0/F days and a heating season greater than eight months.

    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

    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.

    Dentistry is neither an allied health profession nor a paramedical profession. It is the only anatomically focused health care profession that is university-based and for which primary care responsibility is maintained by the profession. Dentists must have a reliable knowledge of basic clinical medicine for safely and effectively treating individuals with chronic and other diseases, which make them biologically and pharmacologically compromised. With changes in the life expectancy of people and lifestyles, as well as rapid advancement in biomedical sciences, dentists should have similar knowledge like a physician in any other fields of medicine. There are number of primary care activities that can be conducted in the dental office like screening of diabetics, managing hypertension etc., The present review was conducted after doing extensive literature search of peer-reviewed journals. The review throws a spotlight on these activities and also suggests some the measures that can be adopted to modify dental education to turn dentists to oral physicians. PMID:25810982

    This paper reviews Minimally Invasive Dentistry (MID) from a day-to-day dentistry perspective, focusing mostly on cariology and restorative dentistry, even though it embraces many aspects of dentistry. The concept of MID supports a systematic respect for the original tissue, including diagnosis, risk assessment, preventive treatment, and minimal tissue removal upon restoration. The motivation for MID emerges from the fact that fillings are not permanent and that the main reasons for failure are secondary caries and filling fracture. To address these flaws, there is a need for economical re-routing so that practices can survive on maintaining dental health and not only by operative procedures.

    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.

    One of the main goals of RENO (Reactor Experiment for Neutrino Oscillation) is to measure the smallest neutrino mixing angle θ{sub 13} using reactor neutrinos in Korea. RENO is the first reactor experiment taking data with two identical detectors in different locations (Near and Far), which is critical to reduce systematic uncertainty in reactor neutrino flux. Our data taking has been almost continuous since Aug. 2011 and we have collected about 434,000 (54,000) electron anti-neutrinos in the Near (Far) detector by 2013. Using this data (about 800 live days) we present a new result on θ{sub 13}: sin{sup 2}2θ{sub 13} = 0.101 ± 0.008 (stat.) ± 0.010 (syst.). We also report the 5 MeV excess present in the prompt signal spectrum in our data, and its correlation with our reactor thermal power.

    Indian women, have come up a long way during the past 50 years. Gone are the days when the leadership positions in dentistry and health care professions were occupied solely by males and the women in-charge were looked down upon as anomalies. The staff rooms in dental and medical schools, the research laboratories in India today are employing women, who have quietly begun challenging the conventional male ideas that had shaped the policies earlier on. Women have advanced considerably in academic dentistry but like every coin, this story too, has two sides. In spite of the considerable gain in equity of status, women in research and academic careers related to health care professions still face innumerable barriers to their careers. This study was conducted with an aim to highlight the various barriers being faced by women in leadership positions in academic dentistry in India and this paper also suggests issues which require global concern for unbiased advancement of women. This was a questionnaire-based study in which the subjects were women in leadership positions in the various dental colleges in India. The questions are related to the various barriers like family commitments, attitude of the society, sexual harassment, gender bias and lack of cooperation from spouse which hinders the development of the careers of such women with tremendous potential. The results show that 67% of the subjects feel there are more barriers to their careers as women than men and health care professions definitely need more women leaders for improvement in women's health status globally. 63.5% of women in dentistry feel their family commitments are barriers to rising in their careers and 64.7% report that a marriage is happier if the husband's career graph is better than wife's. The survey results indicate that the same salary is paid to 93.5% women as their male colleagues. The results of the study show that there certainly has been a change in outlook of Indian women as they have

    To improve the effectiveness of teaching professionalism, the authors propose introducing mindfulness practice into the dental curriculum. The qualities cultivated through mindfulness meditation practice closely resemble the global attitudes of professionalism. Professionalism and mindfulness are broad overlapping constructs with a common prosocial aim: letting go of selfish, short-sighted rewards and promoting the long-term common good. Both constructs also aim for the highest quality of life for practitioners and patients alike. Based on a selective review of the medical literature, we suggest that mindfulness practice should help improve attentiveness, self-awareness, acceptance, wisdom, and self-care in dentistry. We briefly review the role of mindfulness in higher education, as well as current attempts at Dalhousie University to integrate mindfulness into the dental and dental hygiene curricula.

    Electronic publishing is expanding very rapidly and will soon substitute in part for the traditional role of paper and printing in accessing information and in its library storage. This change is occurring now for medicine and engineering. For dentistry the compact disc (CD-ROM) would have advantages over tape or on-line computer systems; one or two discs a year could hold all current dental journal and textbook literature. The setting of standards is the key to the successful introduction of this technology through production and playback systems. Indexing, retrieval and hardware are considered as well as copyright problems. The profession has the chance to guide the introduction of this publishing system in preference to it being fragmented between multiple publishers and thereby becoming costly. A proposal is offered which includes the nexus of traditional printing with this new publishing form through a forum for considering standards and goals for agreement on principles. PMID:2703262

    One of the main objectives of contemporary dentistry is to preserve healthy tooth structure by applying techniques of noninvasive treatment. Air abrasion is a minimally invasive nonmechanical technique of tooth preparation that uses kinetic energy to remove carious tooth structure. A powerful narrow stream of moving aluminum-oxide particles hit the tooth surface and they abrade it without heat, vibration or noise. Variables that affect speed of cutting include air pressure, particle size, powder flow, tip's size, angle and distance from the tooth. It has been proposed that air abrasion can be used to diagnose early occlusal-surface lesions and treat them with minimal tooth preparation using magnifier. Reported advantages of air abrasion include reduced noise, vibration and sensitivity. Air abrasion cavity preparations have more rounded internal contours than those prepared with straight burs. This may increase the longevity of placed restorations because it reduces the incidence of fractures and a consequence of decreased internal stresses. However, air abrasion cannot be used for all patients, i.e. in cases involving severe dust allergy, asthma, chronic obstructive lung disease, recent extraction or other oral surgery, open wounds, advanced periodontal disease, recent placement of orthodontic appliances and oral abrasions, or subgingival caries removal. Many of these conditions increase the risk of air embolism in the oral soft tissues. Dust control is a challenge, and it necessitates the use of rubber dam, high-volume evacuation, protective masks and safety eyewear for both the patient and the therapist.

This study aimed to determine the knowledge, awareness, and attitude of dentistry students towards evidence-based dentistry. Methods In this cross-sectional study, all dentistry students who were studying in their sixth semester and higher in the Kerman School of Dentistry (n = 73) were studied. The data were analyzed using SPSS version 17 and the independent-samples t-tests and the ANOVA test. Results The means of the students’ knowledge, awareness, and attitude scores were 29.2 ± 10.8, 29.9 ± 8.12 and 44.5 ± 5.3, respectively. Among demographic variables, only the number of semesters showed a significant difference with knowledge, awareness, and attitude of dentistry students toward evidence-based dentistry (p = 0.001). Conclusion According to the results of this study, knowledge and awareness of dentistry students at Kerman University of Medical Sciences towards evidence-based dentistry were average and have a neutral attitude. Thus, providing necessary training in this regard will cause promoting the knowledge, awareness, and improved attitudes of dentistry students. PMID:27382446

    Dentistry in Hong Kong during this century has advanced from an informal streetside practice to a discipline that now serves the community by way of registered oral health care personnel. Throughout the years, public attitudes towards dental care have also changed: from a palliative approach involving the extraction of teeth when pain arose, to the prevention of dental disease even at the formative stage of dentition through water fluoridation, regular therapeutic care, and oral health maintenance. The education and professionalisation of practitioners has evolved from apprenticeship to the establishment of a structured university curriculum and postgraduate specialist training of international standards.

  17. Significance of biofilms in dentistry.

    PubMed

    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.

    ASP practice management systems are a new and potentially useful service for the dental profession. ASP systems have the potential to reduce the time, effort, and expense required to maintain computer-based practice management functions. ASP systems can deliver a rich array of functions at a distance, eliminate concerns about upgrades, back-ups, and server hardware, and make management of client workstations easier. The ASP industry is young, however, and its companies and products will be in constant flux. Practitioners should exercise great caution in selecting an ASP system. If the ASP model proves viable in dentistry over the long term, we can expect to see a growing number of services being delivered over the Internet. Many ASPs exist already that serve many needs of small businesses, such as accounting, personnel management, and supply ordering. Application service provider systems also have the potential to improve communication between dental care providers. The ease of exchanging selected patient information between providers may result in more patient-related information exchange than is currently the case. The quality of dental care can only benefit.

    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.

    Conservation of deciduous teeth with pulp alterations caused by caries and trauma is a major therapeutic challenge in pediatric dentistry as a result of the internal anatomy and life cycle characteristic. It is essential that the root canal procedures sanitizers have a performance in eliminating bacterial. In this context, antimicrobial photodynamic therapy (PAT) is promising and emerging as adjuvant therapy in an attempt to eliminate the microorganisms persistent to chemi-mechanical preparation. Since there is presence of oxygen in cells, photosensitizer activated by light can react with molecules in its vicinity by electrons' or hydrogen's transfer, leading to microorganism death. This paper reports the case of 4-year-old patient, female, with early childhood caries. The proposed endodontic treatment incuded chemomechanical treatment allied to PAT in the decontamination of root canals using methylene blue dye 50 μg/mL during 3–5 minutes and 40 J/cm2 as energy density, taking into account the need for tissue penetration and effectiveness of PAT inside the dentinal tubules.

    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.

    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. PMID:22764439

    The proposed action involves the development of geothermal wells to provide hot water and heat for five users in Reno, Nevada. Data from nearby wells indicate the sufficient hot water is available from the Moana Known Geothermal Resource Area for this action. Construction activities have been planned to minimize or eliminate problems with noise, runoff, and disturbance of biota as well as other potential environmental effects. Disposal of the geothermal fluids via surface water or injection will be determined based on water quality of the geothermal fluids and geologic effects of injection. The affected environment is described by this document and needed mitigation procedures discussed.

    Before 1979, there were only 5 undergraduate dental schools in Iran with a total admission of 200 students per year, and only 2,000 dentists and about 50 specialists practicing in the country. Currently, there are 18 dental schools with a total admission of 750 undergraduate students, 5 postgraduate programs in 10 disciplines with a total of 100 students, more than 11,000 dentists (1 dentist per 5,500 population) and nearly 1,000 specialists in the country. Two new schools have recently begun offering specialty training courses in 2 disciplines. The length of the dentistry curriculum is 6 years. Students take general and basic science courses during the first 2 years, then continue on the predental and dental courses for the remaining 4 years. The curriculum has been revised over the past 20 years to establish intership and specialty programs and introduce courses reflecting current trends in the dental profession. Dental services in Iran are provided by both public and private sectors. Oral health care was integrated into the Public Health Care network by 1997, and 4 levels of a Dental Health Care Delivery System were established. The first level is concerned with primary prevention at 'health houses', where auxiliary health workers called 'behvarzes' provide periodic examinations, referrals, and oral health education. At the next level, oral hygienists and dentists in 'health centers' perform basic oral health care services such as fillings, scaling, and extraction. At the third level, dentists manage and treat oral diseases in 'urban health centers', while the last level is for advanced treatment by specialists in university health centers in the cities.

    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 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.

  8. Quaternary extensional growth folding beneath Reno, Nevada, imaged by urban seismic profiling

    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 established importance of Forensic Dentistry for human identification, mainly when there is little remaining material to perform such identification (e.g., in fires, explosions, decomposing bodies or skeletonized bodies), has led dentists working with forensic investigation to become more familiar with the new molecular biology techniques. The currently available DNA tests have high reliability and are accepted as legal proofs in courts. This article presents a literature review referring to the main studies on Forensic Dentistry that involve the use of DNA for human identification, and makes an overview of the evolution of this technology in the last years, highlighting the importance of molecular biology in forensic sciences.

    This paper explores the entrepreneurial role of dentists in primary care dentistry. 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. PMID:22402534

    The purpose of coatings on implants is to achieve some or all of the improvements in biocompatibility, bioactivity, and increased protection from the release of harmful or unnecessary metal ions. During the last decade, there has been substantially increased interest in nanomaterials in biomedical science and dentistry. Nanocomposites can be described as a combination of two or more nanomaterials. By this approach, it is possible to manipulate mechanical properties, such as strength and modulus of the composites, to become closer to those of natural bone. This is feasible with the help of secondary substitution phases. Currently, the most common composite materials used for clinical applications are those selected from a handful of available and well-characterized biocompatible ceramics and natural and synthetic polymers. This approach is currently being explored in the development of a new generation of nanocomposite coatings with a wider range of oral and dental applications to promote osseointegration. The aim of this review is to give a brief introduction into the new advances in calcium phosphate nanocoatings and their composites, with a range of materials such as bioglass, carbon nanotubes, silica, ceramic oxide, and other nanoparticles being investigated or used in dentistry.

    Dentistry is most importantly and foremost a healing profession. In today’s world, it is very necessary to understand the importance of being eco-friendly in every facet of our lives, including dental practice which has a huge impact on the environment due to the large amount of metallic waste generated by various dental procedures along with excessive use of water and electricity, which specifically emphasis the thrust to move towards ‘Green dentistry’. Green dentistry is an innovative way of dental practice which is environment friendly and at the same time conserves money and time by reducing waste, conserving energy and decreasing pollution with the use of latest techniques and procedures. Green dentistry therefore, protects the environment and mankind from the hazards of rapid urbanisation in developing countries. The authors wish to emphasize the practice of eco-friendly, green dentistry in a developing country like India which needs to conserve resources and curb environmental pollution. PMID:25177666

    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

    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. PMID:12125697

    Urolithiasis has an important role in the structure of urological pathology, due to its high incidence, frequency of recurrence and complications it might cause. There are many methods of treatment for kidney stones described in the scientific literature as conservative, surgical, laparoscopic, endoscopic, and ESWL. In this study, we have analyzed the ESWL method of treatment of reno-ureteral stones.There are still many controversies about the effectiveness of different models of lithotripters but the lithotripter type Modulith SLK Storz Medical (Germany) used in our clinic has proved to be very effective. ESWL is currently the first-line treatment for the majority of kidney and ureteral stones, which are up to 20 mm in diameter.

    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.

    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.

    Dentistry has a long, often well documented history. Evidence of tooth pullings has been discovered in crude carvings on the walls of caves that are over 10,000 years old. The ancient Egyptians, the Athenians, and the early inhabitants of Rome required oral health care; in addition to tooth extractions, they underwent tumor removal, tamponade for hemorrhage, reduction of jaw fractures with gold wire ligatures, cautery using white hot platinum loops, and an additional variety of remedies and nostrums. Pain relief was offered, with courses of treatment as varied as postural change, alteration of ambient temperature, and vegetable and organic medicines in poultices or via oral and rectal routes. Through the centuries, great surgeons and physicians introduced various methods of treatment: Hippocrates codified ethical standards; Maimonides established pragmatic rules for physicians; LeFort categorized facial fractures; Pasteur clarified the need for sterilization; Semmelweis standardized antiseptic conditions in the operating theater; Morton and Wells discovered safer methods of analgesia; Freud explored the theraupeutic uses of narcotics; Roentgen championed X-ray imaging; Curie pioneered the use of chemotherapy; and Barton and Nightingale were models of empathy and patient care. In more recent times, we have profited from the genius of Watson and Crick (DNA); Fleming (penicillin); Venable and Stuck (Chrome-cobalt--molybdenum alloy); Gershkoff and Goldberg (the subperiosteal implant); Chercheve, Branemark, Linkow, Misch, Tatum, and Niznick (innovative root forms, titanium and its alloys, and sinus floor grafting). The 20th century has brought to us phenomenal imaging, breathtaking intrauterine fetal surgery, wildly promising stem cell research, and astonishing CADCAM techniques. We've had great teachers and clinicians who have introduced us to new forms of therapy and advanced methods, including the role of the hemidesmasomes, the essential elements of bone grafting

    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.

    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. PMID:25201627

    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.

  15. Emergency medicine in pediatric dentistry: preparation and management.

    PubMed

    Malamed, Stanley F

    2003-10-01

    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.

    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

    2005-01-01

    Composite resin has been used for nearly 50 years as a restorative material in dentistry. Use of this material has recently increased as a result of consumer demands for esthetic restorations, coupled with the public's concern with mercury-containing dental amalgam. Composite is now used in over 95% of all anterior teeth direct restorations and in 50% of all posterior teeth direct restorations. Carbon fiber reinforced composites have been developed for use as dental implants. In medicine, fiber-reinforced composites have been used in orthopedics as implants, osseous screws, and bearing surfaces. In addition, hydroxyapatite composite resin has become a promising alternative to acrylic cement in stabilizing fractures and cancellous screw fixation in elderly and osteoporotic patients. The use of composite resin in dentistry and medicine will be the focus of this review, with particular attention paid to its physical properties, chemical composition, clinical applications, and biocompatibility.

    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.

    Propolis, known as bee glue, is a wax-cum-resin substance, which is created out of a mix of buds from some trees with the substance secreted from the bee's glands. Its diverse chemical content is responsible for many valuable properties. Multiple applications of propolis have been studied and described in detail for centuries. However, currently available information on propolis is scarce. A literature search in the PubMed database was performed for English language articles, using the search terms propolis, oral health, dentistry, and oral cancer; no restrictions were used for publication dates. The aim of the article was to review propolis and its applications in dentistry including oral cancer. PMID:25006559

    Digital communication offers advantages and challenges to dental practice. As dentistry becomes comfortable with this technology, it is essential that commercial and other values not be accepted on a par with professional ones and that the traditional dentist-patient relationship not be compromised by inserting third parties that introduce nonprofessional standards. The Officers and Regents of the American College of Dentist have prepared this background and position paper as a guide to the ethical use of digital communication in dental practice.

    Prehistoric evidence for the drilling of human teeth in vivo has so far been limited to isolated cases from less than six millennia ago. Here we describe eleven drilled molar crowns from nine adults discovered in a Neolithic graveyard in Pakistan that dates from 7,500-9,000 years ago. These findings provide evidence for a long tradition of a type of proto-dentistry in an early farming culture.

    Restorative materials in pediatric dentistry have to fulfill special requirements. They should be easy to handle and applicable in a not always dry mouth. They should potentially be adhesive in order to avoid too much mechanical preparation. They do not have to be extremely wear resistant as the dwell time of the restorations is relatively short. Glass-ionomer cements and in particular the resin modified types possess properties which make them almost ideal for the required purpose.

    PubMed

    Brostek, Andrew M; Bochenek, Andrew J; Walsh, Laurence J

    2006-06-01

    The term "Minimal Invasive (MI) Dentistry" can best be defined as the management of caries with a biological approach, rather than with a traditional (surgical) operative dentistry approach. Where operative dentistry is required, this is now carried out in the most conservative manner with minimal destruction of tooth structure. This new approach to caries management changes the emphasis from diagnosing carious lesions as cavities (and a repeating cycle of restorations), to one of diagnosing the oral ecological imbalance and effecting biological changes in the biofilm. The goal of MI is to stop the disease process and then to restore lost tooth structure and function, maximizing the healing potential of the tooth. The thought process which underpins this new minimal invasive approach can be organized into three main categories: (1) Recognize, which means identify patient caries risk, (2) Remineralize, which means prevent caries and reverse non-cavitated caries, and (3) Repair, which means control caries activity, maximize healing and repair the damage. The disease of dental caries is not just demineralization, but a process of repeated demineralization cycles caused by an imbalance in the ecological and chemical equilibrium of the biofilm /tooth interface (the ecological plaque hypothesis). Dietary and lifestyle patterns, especially carbohydrate frequency, water intake and smoking, play an important role in changing the biofilm ecology and pathogenicity. Tools for chairside assessment of saliva and plaque, allow risk to be assessed and patient compliance monitored. The remineralizing properties of saliva can be enhanced using materials which release biologically available calcium, phosphate and fluoride ions (CPP-ACP and CPP-ACFP). Use of biocides can also alter the pathogenic properties of plaque. Use of these MI treatment protocols, can repair early lesions and improve patient understanding and compliance. This review article introduces some of the key concepts

    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.

    Polymerization of Resin Based Composites (RBCs) initiated by a light curing unit activating photoinitiators. Different RBCs require different light energy levels for proper curing. Manufacturers are now producing RBCs with more than one initiator and not all of these will be properly polymerised with blue LED lights. An added problem is that manufacturers do not always indicate the type of photoinitiators in their materials. This review discusses the importance of matching the spectral output of LCUs to the absorption spectra of RBCs and the consequences of spectral mismatch. Resin based composites (RBCs) were first introduced in the 1960s and with development of effective and reliable dentine bonding systems2, have been used routinely as a filling material for both anterior and posterior teeth. The early RBCs were either chemically cured two component materials or photo-initiated materials that used UV initiators in the beginning and then transitioned to visible light initiators such as camphorquinine which was introduced in 1978.3 The first report of a light curing material was of an ultraviolet (UV) cured fissure sealant. However, due to the limited penetration depth of the UV light and the potential health hazards, this system was quickly abandoned. The advancement of science yielded light curing materials which contributed to a significant clinical progress over the UV and chemically cured RBCs. Additional advancements to direct RBC restoration materials included luting agents for ceramic restorations, pit and fissure sealants and resin modified glass ionomers. Polymerization in an RBC is initiated by a light curing unit (LCU); this technology is based on the use of photoreactive systems that absorb light irradiation from the LCUs at appropriate wavelength. Then the photoinitiators contained in the RBCs, absorb the incoming photons from the LCU and the monomers in the molecular structure become excited and in that active state, there is a change from monomers

    Background Acute renal failure from ischemia significantly contributes to morbidity and mortality in clinical settings, and strategies to improve renal resistance to ischemia are urgently needed. Here, we identified a novel pathway of renal protection from ischemia using ischemic preconditioning (IP). Methods and Findings For this purpose, we utilized a recently developed model of renal ischemia and IP via a hanging weight system that allows repeated and atraumatic occlusion of the renal artery in mice, followed by measurements of specific parameters or renal functions. Studies in gene-targeted mice for each individual adenosine receptor (AR) confirmed renal protection by IP in A1−/−, A2A−/−, or A3AR−/− mice. In contrast, protection from ischemia was abolished in A2BAR−/− mice. This protection was associated with corresponding changes in tissue inflammation and nitric oxide production. In accordance, the A2BAR-antagonist PSB1115 blocked renal protection by IP, while treatment with the selective A2BAR-agonist BAY 60–6583 dramatically improved renal function and histology following ischemia alone. Using an A2BAR-reporter model, we found exclusive expression of A2BARs within the reno-vasculature. Studies using A2BAR bone-marrow chimera conferred kidney protection selectively to renal A2BARs. Conclusions These results identify the A2BAR as a novel therapeutic target for providing potent protection from renal ischemia. PMID:18578565

    The RENO experiment has analyzed about 500 live days of data to observe an energy dependent disappearance of reactor ν[over ¯]_{e} by comparing their prompt signal spectra measured in two identical near and far detectors. In the period between August of 2011 and January of 2013, the far (near) detector observed 31 541 (290 775) electron antineutrino candidate events with a background fraction of 4.9% (2.8%). The measured prompt spectra show an excess of reactor ν[over ¯]_{e} around 5 MeV relative to the prediction from a most commonly used model. A clear energy and baseline dependent disappearance of reactor ν[over ¯]_{e} is observed in the deficit of the observed number of ν[over ¯]_{e}. Based on the measured far-to-near ratio of prompt spectra, we obtain sin^{2}2θ_{13}=0.082±0.009(stat)±0.006(syst) and |Δm_{ee}^{2}|=[2.62_{-0.23}^{+0.21}(stat)_{-0.13}^{+0.12}(syst)]×10^{-3}  eV^{2}.

    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.

    We have studied the role of afferent renal nerve fibres in anaesthetized cats in mediating the decrease in sodium and water excretion from the contralateral kidney caused by unilateral renal denervation. Transient denervation of one kidney obtained by cooling of the left renal nerves increases contralateral efferent renal nerve activity and decreased sodium and water excretion from the opposite kidney. The results observed in animals with intact neural pathways were compared with those obtained after the left kidney had been selectively deafferentated by cutting the dorsal roots from T9 to L4. Bilateral section of dorsal roots did not affect the increase in sodium and water excretion from the transiently denervated left kidney, but entirely abolished the decrease in sodium and water excretion from the contralateral kidney. Neither the left nor the right dorsal root section alone, affected the response of the contralateral right kidney. Our data demonstrate that afferent renal nerve fibres project bilaterally to the spinal cord and form the afferent branch of the reno-renal reflex by which one kidney can control the function of the opposite one.

    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.

    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.

    In this era of fast developing technologies and innovative ideas, the need for faster treatment has become a necessity. Treatment with lasers that is much less time-consuming and painless is accepted and appreciated by the patient. Use of Lasers is not new; they have been in use for decades since their development by Maiman in 1960. Lasers have travelled a long way from ruby lasers to erbium lasers and are being fondly used in every aspect of dental treatment. This article aims at elaborate the use and applications of lasers in the field of esthetic dentistry. PMID:26124614

    Probiotics are dietary supplements, which have been advocated for the prevention and the treatment of a wide range of diseases. These products consist of beneficial micro-organisms, which stimulate health promoting flora thus, suppressing the pathologic colonization and disease spread. Since, probiotics are now widely used in both medical (such as cancer risk reduction, gastrointestinal tract health, and urinary tract health) and dental specialties (reduction in caries development, in achieving periodontal health, reducing oral malodor, etc.), a thorough understanding of their risks and benefits are essential. This review focuses on the recent trends in use of probiotics in dentistry as well as the potential risks associated with them. PMID:24019796

    The concept of minimally invasive dentistry will provide favorable conditions for the use of composite resin. However, a number of factors must be considered when placing composite resins in conservatively prepared cavities, including: aspects on the adaptation of the composite resin to the cavity walls; the use of adhesives; and techniques for obtaining adequate proximal contacts. The clinician must also adopt an equally conservative approach when treating failed restorations. The quality of the composite resin restoration will not only be affected by the outline form of the preparation but also by the clinician's technique and understanding of the materials.

    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.

    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

    Neuromuscular dentistry has been a controversial topic in the field of dentistry and still remains debatable. The issue of good occlusion and sound health has been repeatedly discussed. 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. PMID:25737904

    2007-05-26

    As a profession we have a responsibility to ensure that the oral health needs of individuals and groups who have a physical, sensory, intellectual, medical, emotional or social impairment or disability are met. In the UK, over 200,000 adults have profound learning disabilities and/or complex medical conditions. Adults with a disability often have poorer oral health, poorer health outcomes and poorer access to services than the rest of the population. This paper examines the need for Special Care Dentistry based on a review of published literature, surveys and health policy, and suggests how services might be delivered in the future. Existing models of good practice reveal that established clinicians working in this field have a patient base of between 850 and 1,500 patients per year and work across primary care and hospital settings, liaising with colleagues in health, social services and the voluntary sector to ensure integrated health care planning. On this basis, a conservative estimate of 133 specialists is suggested for the future, working in networks with Dentists with Special Interests (DwSIs) and primary dental care practitioners. A skilled workforce that can address the wider needs of people requiring Special Care Dentistry should be formally recognised and developed within the UK to ensure that the needs of the most vulnerable sections of the community are addressed in future.

    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

    The Moana geothermal systems, located in Reno, Nevada, is a moderate-temperature geothermal resource used for space heating applications. Both historic and new hydrologic, thermal, and groundwater chemistry data were collected to evaluate the Moana system and to develop a calibrated numerical model of the geothermal aquifer for investigation of resource development scenarios. The new data collection consisted of static water level measurements and temperature with depth measurements for a 13-month period at 26 geothermal wells to investigate hydrologic and thermal changes with time. In addition, groundwater chemistry sampling at 10 wells was used to evaluate mixing of thermal and nonthermal waters. Collected information indicates that in the most heavily used portion of the geothermal aquifer, the hydraulic heads have declined. This decline may induce additional leakage of cooler water from the overlying unconfined aquifer and lead to decreased temperatures at well locations in the geothermal aquifer. The groundwater chemistry data show concentration changes with temperature for boron, chloride, fluoride, lithium, and bicarbonate that are a function of the degree of mixing of thermal and nonthermal waters. Temporal changes in these constituents may be used as an indication of relative temperature changes in the geothermal system caused by mixing at a given location. An attempt was made to use the hydraulic head and maximum temperature data to develop a calibrated numerical model for the Moana geothermal system. However, lack of information about the horizontal and vertical thermal and fluid fluxes made the development of a calibrated model not possible at this time. 25 refs., 54 figs., 6 tabs.

    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

    The experiments were performed to study the role of the renal nerves and the reno-renal reflexes in the control of water and sodium excretion in spontaneously hypertensive rats (SHR) compared to their normotensive controls, Wistar Kyoto (WKY) rats. Unilateral renal denervation in anaesthetized animals produced a slight, progressive decrease in arterial pressure in both WKY and SHR rats. The glomerular filtration rate temporarily increased in the kidney that underwent the denervation in the SHR group only. After unilateral renal denervation a sharp increase in water and sodium excretion from the ipsilateral kidney was observed in both WKY and SHR. One hour after the denervation, the percent changes in water and sodium excretion were smaller in WKY (+32 +/- 19% and +24 +/- 17%) than in SHR rats (+84 +/- 15% and +93 +/- 20%). In the kidney contralateral to the denervation a reduction in water and sodium excretion was observed and this reduction was prompter in SHR than in WKY rats. One hour after the denervation, the percent changes in water and sodium excretion were similar in WKY (-21 +/- 8% and -18 +/- 7%) and SHR (-19 +/- 6% and -19 +/- 7%). In control groups, sham denervation did not cause significant changes in glomerular filtration rate, and urinary water and sodium excretion. Arterial pressure slightly and progressively decreased in both control groups. Electrical stimulation of the efferent renal nerves performed in WKY and SHR produced similar decreases in renal blood flow, glomerular filtration rate, and water and sodium excretion in the two groups for the same frequencies of stimulation. As this finding indicates that renal targets in hypertensive rats are normally responsive to the neural drive, our data demonstrate that renal responses to unilateral renal denervation in hypertensive rats are equal to the responses observed in normotensive rats. Our results indicate that tonically active inhibitory renorenal reflexes normally operate in spontaneously

    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.

    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.

    Objective Develop and validate an initial content taxonomy for patient records in general dentistry. Methods Phase 1–Obtain 95 de-identified patient records from 11 general dentists in the United States. Phase 2–Extract individual data fields (information items), both explicit (labeled) and implicit (unlabeled), from records, and organize into categories mirroring original field context. Phase 3–Refine raw list of information items by eliminating duplicates/redundancies and focusing on general dentistry. Phase 4–Validate all items regarding inclusion and importance using a two-round Delphi study with a panel of 22 general dentists active in clinical practice, education, and research. Results Analysis of 76 patient records from 9 dentists, combined with previous work, yielded a raw list of 1,509 information items. Refinement reduced this list to 1,107 items, subsequently rated by the Delphi panel. The final model contained 870 items, with 761 (88%) rated as mandatory. In Round 1, 95% (825) of the final items were accepted, in Round 2 the remaining 5% (45). Only 45 items on the initial list were rejected and 192 (or 17%) remained equivocal. Conclusion Grounded in the reality of clinical practice, our proposed content taxonomy represents a significant advance over existing guidelines and standards by providing a granular and comprehensive information representation for general dental patient records. It offers a significant foundational asset for implementing an interoperable health information technology infrastructure for general dentistry. PMID:23838618

  1. How dentistry should approach its problems: a vote for professionalism.

    PubMed

    Rule, James T

    2010-01-01

    Dentistry, like all professions, has always had ethical problems to contend with, including societal trust, flagrant advertising, commercialism, and access to care. Although the profession's interest and expertise in ethics has grown enormously in the last three decades, the issues facing dentistry have not really decreased, and perhaps have grown more problematic. Thus, despite the invaluable contributions of ethical progress to the structure and function of our profession, this paper argues that reflective ethics by itself appears unable to exact change. For change to occur, dentistry also needs a broad-based display of enlightened, and ethically-driven but action-oriented professionalism. This existed in the 1830s when U.S. dentistry was in its early stages of becoming thought of as a profession. Using the lessons learned from that period of our history, we need to do the same thing now--not excluding ethics, but working hand in glove with ethics. This paper suggests that, as in the 1830s, dentistry now needs the grassroots attention of its membership. Using recent publications about the importance of "connectedness" in dentistry, guidelines are presented that provide a framework for approaching the problems faced by dentistry and contributing to a more satisfying professional career.

    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.

    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.

    1997-01-01

    In the history of many professions there are periods of more or less pronounced borderline fights against other professions and/or charlatans. This article is about such an example from the profession of dentistry in Sweden. From the middle of the second decade of this century, there was an increasing discrepancy between the need for dental care and the too low number of dentists. Furthermore: the majority of the Swedish people could not afford dental care at all. In the public debate the concept "dental misery" was created. In 1919 a famous Swedish paediatric professor, Isak Jundell, presented a debate article in "Allmänna Svenska Läkartidningen" (Journal of the Swedish Medical Association), with a proposal for building up a corps of dental assistants with shorter training than dentists, but still with competence for tooth cleaning, extraction and some operative dentistry. The aim of the proposal was to give people easier available and cheaper dental care. The dental profession had been questioned and threatened and the reaction from the advocates of the dentists was immediate and intense. Now followed an almost five year long struggle, with the Swedish Dental Association on one side and parts of the medical profession, dental technicians, even some dentists and a number of politicians on the other. The controversy ended up in the Swedish Parliament in 1924 where many members in both the chambers had signed motions concerning authorisation of dental technicians. The dentists won the fight thanks to the resolution in the Parliament not to authorise the technicians. But still more important, from a social political point of view, was a statement from the Parliament with a commission to the Government to analyse the prerequisites for building up a Public Dental Health Service organisation in Sweden. After a series of committees this was finally a reality fourteen years later, in 1938, when the Parliament in a resolution initiated "folktandvården".

    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.

  10. RENO-CC: A new system to fuel lattice design in boiling water reactors using neural networks

    2006-07-01

    We show a new system to optimize fuel lattices in BWRs named RENO-CC. The system employs a multi state recurrent neural network (MSRNN) for optimizing a fuel lattice pin-by-pin {sup 235}U enrichment distribution. Local Power Peaking Factor (LPPF) and k-infinite (k{sub {infinity}}) are involved in the MSRNN energy function. Both parameters are calculated by the 2D HELIOS transport code for lattice burn-up. Through the iterative process the MSRNN decreases PPF value while k{sub {infinity}}, is kept in a rank of values, at the beginning of lattice life (BOL). The iterative process ends after 20 iterations. If PPF is not lower than limit, RENO-CC applies a fuzzy logic rule in order to recommend if the fuel lattice has an acceptable LPPF value and it might eventually be used in a fuel load. When a fuel lattice is obtained it can be used into a fuel assembly. And eventually, this fuel assembly would be used in the process of fuel load and control rod patterns optimization. So, a 3D core reactor calculation must decide if such a lattice design can fulfill the operation conditions into the reactor core. Preliminary results are shown in this paper. (authors)

    In pediatric renal transplantation in the setting of IVC thrombosis, the retrohepatic IVC or gonadal veins are often used for outflow. However, if use of systemic venous outflow is unsuccessful, options become limited. We report the use of the portal vein for venous outflow in kidney retransplantation in the setting of IVC thrombosis. The patient is a 19-month-old male who developed end-stage renal failure at seven months of age secondary to hypotension after spontaneous rupture of an accessory renal vein. The IVC was occluded during emergent laparotomy, and the patient developed extensive IVC thrombosis. The first two transplant attempts used the retrohepatic IVC for venous outflow. Despite good initial flow, in both instances the renal vein thrombosed on post-operative day 1. In an unsuccessful salvage attempt of the second transplant, a reno-portal anastomosis was performed. With few options for vascular access, a third transplant was attempted. The reno-portal stump from the second transplant was used for outflow. The patient recovered well from his third transplant (creatinine 0.6 mg/dL 35 months post-surgery), demonstrating that the portal vein can be used for outflow in cases of extensive IVC thrombosis.

    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. PMID:15530264

    Purpose The purpose of this paper is to explore selective leadership approaches in the context of dentistry in the UK. Design/methodology/approach This is a conceptual paper utilising published sources from relevant literature about leadership theory and practice and the policy background to dentistry in the UK. Findings This paper suggests that there is merit in identifying and applying an eclectic mix of leadership theory to the case of dentistry. It offers insight into individual aspects of the leadership role for dentists and applies this to the dental context. It also contrasts these individual approaches with shared leadership and suggests this may also be relevant to dentistry. It highlights the fact that leadership will be of growing concern for dentistry in the light of recent policy changes. Research limitations/implications This paper points out that there are developmental implications depending on the particular approach taken. It argues that leadership development will become increasingly important in dentistry in the UK. Originality/value This paper addresses a topic that has so far received limited attention in the literature.

    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.

    PubMed

    Little, James W

    2004-08-01

    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.

    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.

  8. Minimally invasive dentistry and the dental enterprise.

    PubMed

    Rossomando, Edward F

    2007-03-01

    Improvements in understanding the process of remineralization have resulted in a reappraisal of repair of damaged tooth structure and call into question the principles of cavity preparation of GV Black and his principle of "extension for prevention." From this reappraisal has emerged the idea of minimally invasive dentistry (MID). The goal of MID is to remove as little of the sound tooth structure during the restoration phase as possible. This goal is in our reach in part because of availability of products that promote mineralization and of dental excavation instruments, like the dental laser, that can be managed to remove only damaged tooth structure. It is critical that the leaders of the dental enterprise endorse MID. Delay could allow new products to move from the dental profession to other health care providers. For example, a caries vaccine will soon enter the market place. Will dentists expand the scope of their practices to include the application of this vaccine, or will they ignore this new product and allow the new technology to enter the scope of practice of other health providers?

    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.

    Surface disinfection is a procedure carried out on the external parts of the dental equipment as well as on other items of the dental office. The aim of this study was to analyze the efficacy of 4 surface disinfectants utilized in dentistry: 77 degrees GL alcohol, phenolic compound (Duplofen), iodophor (PVP-I) and 77 degrees GL alcohol with 5% of chlorhexidine. Four surfaces of the equipment were analyzed in the study (the carter, the washbasin for hand-washing, the headrest of the chair and the external surface of the reflector), and the spray-wipe-spray procedure was carried out. From each surface, samples were collected by means of surface plates containing Mitis Salivarius bacitracin sucrose agar, Sabouraud Dextrose agar with chloramphenicol, MacConkey agar and blood agar, for counting mutans streptococci, Candida yeasts, gram-negative bacteria and total microorganisms, respectively (ufc/plate). The results were statistically analyzed by means of the Student's t test in order to compare the mean ufc/plate values. The most effective disinfectant was 77 degrees GL alcohol with 5% of chlorhexidine, mainly against gram-positive bacteria. Iodophor and phenolic compound were also effective in microbial reduction. 77 degrees GL alcohol was the least effective product - however, although it is not considered as a surface disinfectant, it produced, in this study, statistically significant microbial reduction after the disinfecting procedure.

    The purpose of this study was to examine how patients perceived the professionalism of University of Minnesota School of Dentistry students, faculty, and staff. Professionalism is defined by the authors as an image that will promote a successful relationship with the patient. Patients within comprehensive care clinics were asked to assess physical attributes and behaviors of the dental care providers using a questionnaire. The patients read statements dealing with characteristics of the dental care providers and responded as to whether they agreed, were neutral, or disagreed with the statement. The surveyed population consisted of 103 males and 97 females, 64 percent of whom lacked insurance coverage. Fifty-one percent of the patients were between the ages of forty-four and sixty-nine, but the overall age distribution was dispersed over a range of eighteen to one hundred. Our research found that all dental care providers displayed a professional appearance as well as behavior. The attire of the dental care provider affected the comfort and anxiety levels of patients, as did first impressions of both students and faculty. Most patients reported that students and faculty displayed effective time management and used appropriate language during the appointment. Finally, hairstyle, makeup, and jewelry appeared to have little effect on patients' opinions of the various dental care providers.

    The Truckee River drainage system above Reno, Nevada presents unique examples of complex slope stability problems because of the varied and complex geologic terrane. Several factors control mass wasting and slope stability as the Truckee River flows from the Sierra Nevada to the Basin and Range Physiographic province. A distinct change in climatic conditions occurs. The river passes through Cenozoic jointed and faulted volcanic rocks of various lithologies and competency interspersed with clastics which lend to complex geological problems. The upper canyon is U-shaped and over-steepened by multiple Pleistocene glacial stages. The lower canyon has been incised deeply from periodic outburst flooding originating from glacial dammed lakes in the upper canyon. The area is seismically active which exacerbates the slope instability. These factors together have contributed to approximately five categories of mass wasting.

  13. AIDS: today's vital challenge to dentistry.

    PubMed

    Thompson, E O

    1985-01-01

    This article suggests precautions that should be taken if dentists are to treat acquired immunodeficiency syndrome (AIDS) patients. Dentists are considered to be at higher risk of contracting AIDS than physicians. AIDS patients often present at dental offices seeking treatment for the oral symptoms sometimes associated with the virus. Identification of patients who may have AIDS is a critical factor in establishing treatment and protective guidelines; however, such identification is hindered by the prolonged incubation period. It is suggested that questions identifying symptoms of AIDS should be added to the Medical-Dental History Form (a sample form is included with the article). If responses to this form raise suspicion that a patient might have AIDS, the patient should be referred to his physician before an oral examination is scheduled. There is good evidence that AIDS patients can be safely treated in the dental office if the following precaustions are observed: 1) faithful use of an updated medical-dental history form with the follow-up measures suggested, 2) limitation to an absolute minimum of any dental operations; and 3) control of splashback. It is reasonable to assume that liquids that come from the mouth contain blood, infected fluids, saliva, sputum, and mucus that can act as carriers for the AIDS virus if they become droplets and/or aerosols and are transmitted to others through the mucuous membranes of the mouth or eyes. The use of face masks, washed-field dentistry, the rubber dam, protective eyeglasses, rubber gloves, disposable needles, autocleavable instruments, and disposable cap and gown is advocated to protect dentists from the AIDS virus.

    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).

    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

  16. An interdisciplinary approach to treatment planning in implant dentistry.

    2005-04-01

    The practice of implant dentistry requires an interdisciplinary approach that integrates the knowledge, skills, and experience of all the disciplines of dentistry into a comprehensive treatment plan. The team must examine the anticipated restorative site to determine the suitability of the existing hard and soft tissues for implant placement. Deficiencies in hard and soft tissue, which prevent ideal implant placement, must be recognized and addressed to ensure a more predictable esthetic outcome. This article outlines a comprehensive interdisciplinary treatment philosophy designed for developing the foundation of optimal esthetics in implant dentistry. Cases are presented to illustrate the utility of interdisciplinary treatment in which specialists are recruited to enhance and improve a patient's dental function and esthetics. PMID:15915880

  17. The use of information and communication technology (ICT) in dentistry.

    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. PMID:27386005

    Virtual reality is a computer based technology linked with the future of dentistry and dental practice. The virtual articulator is one such application in prosthetic and restorative dentistry based on virtual reality that will significantly reduce the limitations of the mechanical articulator, and by simulation of real patient data, allow analyses with regard to static and dynamic occlusion as well as to jaw relation. It is the purpose of this article to present the concepts and strategies for a future replacement of the mechanical articulator by a virtual one. Also, a brief note on virtual reality haptic system has been highlighted along with newly developed touch enabled virtual articulator. PMID:25177664

    A damp and dull London day in March somewhat contradicted the title of the meeting of the Odontology Section of the RSM, Let there be light--the laser in dentistry, but there was no doubt, once inside, that the organisers had, with perfect timing, caught the interest of the profession as a Barnes Room packed to capacity was greeted by the president of the section, Margaret Seward. Rather apologetically, she confessed that the film Goldfinger was unavailable, but promised us equal fascination with a galaxy of international experts to guide us through a maze of new developments in laser dentistry.

  1. Local anesthetics: dentistry's most important drugs, clinical update 2006.

    PubMed

    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.

    An adequate understanding of the relationship between periodontal tissues and restorative dentistry is paramount to ensure adequate form, function, esthetics and comfort of the dentition. While most clinicians are aware of this important relationship, uncertainty remains regarding specific concepts such as biologic width, its maintenance and applications of crown lengthening in cases of biologic width violation. Relevant publications regarding biologic width, its violation and management were identified up to August 2011 using manual and electronic database search in Medline, Embase, Directory of Open Access Journals and Google Scholar. This review discusses the concept of biologic width around tooth and its relationship to periodontal health and restorative dentistry. PMID:22368328

    The role that cosmetic dentistry can play in improving one's overall facial esthetics has become increasingly more meaningful to patients, dentists, and physicians as elective cosmetic procedures continue to gain momentum and acceptance in today's Western culture. By incorporating fundamental principals of proper smile design into a total esthetic facial enhancement treatment plan, dramatic improvements may be realized. As cosmetic dentists, maxillofacial surgeons, and orthodontists continue to make successful strides with their physician counterparts, they must continue to emphasize the key role that the smile commands. Although a review of current literature discloses few references to the specific topic of facial enhancements through cosmetic dentistry, it is nonetheless a topic for further discussion.

    1993-07-01

    . When occlusal disharmony has been shown to reactivate a TMD, an equilibration or a more extensive rehabilitation may be necessary in the second phase of TMD treatment. In the symptomatic phase of a TMD, however, only reversible measures are appropriate. In this time of fast-moving change in restorative techniques and products, all operative dentists should raise their consciousness of occlusal principles. Occlusal forces set limits on the selection of materials and often prescribe the design features needed for a successful outcome. With structurally or periodontally compromised teeth, the occlusal planning to minimize nonaxial forces lies at the heart of the restoration. Virtually all restorative dentistry is affected by the occlusal forces of the teeth in function.(ABSTRACT TRUNCATED AT 400 WORDS)

    Every practitioner has the obligation to offer his or her patients the latest advances in their profession. Dentistry has made a shift over the past 50 years from caries restoration and prosthetic replacement to preventative and esthetic rejuvenation. Related dental specialties have also blossomed with new procedures and an expanded scope of practice. This shift has also included more comprehensive care and treatment of the oral and maxillofacial region. Modern esthetic dentists realize the facial soft tissues serve as a frame for their restorative artwork. Contemporary oral and maxillofacial surgery includes cosmetic facial surgery. Procedures for such surgery are taught in oral and maxillofacial surgery residency programs, are part of the oral and maxillofacial surgery board exams, and are covered by oral and maxillofacial surgery malpractice companies. Esthetic dentists should understand facial aging, as well as the basic procedures available for facial rejuvenation by the oral and maxillofacial surgeon. Contemporary esthetic dentistry goes beyond the oral cavity, and the smile is truly enhanced by simultaneous facial rejuvenation. This article discusses the process of perioral facial aging and various cosmetic facial surgery options.

    Reno, Nevada, USA is subject to typical urban aerosol, wind-blown dust, and occasional biomass burning smoke from anthropogenic and natural fires. Reno has complex air flow at levels relevant for aerosol transport. At times recirculating mountain and urban flow arrives from the Sierra Nevada, San Francisco, CA and Sacramento, CA. The urban plumes are further modified by biogenic forest emissions and secondary aerosol formation during transport over the Sierra Nevada Mountains to Reno. This complicates the use of MODIS aerosol optical depth (AOD) for air quality measurements in Reno. Our laboratory at the University of Nevada Reno has collocated multispectral photoacoustic instruments and reciprocal nephelometers to measure light absorption and light scattering coefficients as well as an AERONET operated CIMEL CE-318 ground-based sunphotometer. Preliminary measurements from August 2011 indicate substantially larger Cimel AOD than could be accounted for by use of the in situ aerosol extinction measurements combined with mixing height estimate. This poster presents new results comparing AERONET AOD and single scattering albedo and MODIS AOD with in situ measurements for summer and fall 2012, along with extensive back trajectory analysis, to evaluate conditions when satellite measurement may be useful for air pollution applications in Reno.

During this period postgraduate training, dental health, and the organization of child dental care have changed considerably. Aim. To investigate services provided by specialists in paediatric dentistry in Sweden in 2008, and to compare with data from previous surveys. Design. The same questionnaire was sent to all 30 specialist paediatric dental clinics in Sweden that had been used in previous surveys. Comparisons were made with data from 1983, 1989, 1996 and 2003. Results. Despite an unchanged number of specialists (N = 81 in 2008), the number of referrals had increased by 16% since 2003 and by almost 50% since 1983. There was greater variation in reasons for referrals. The main reason was still dental anxiety/behaviour management problems in combination with dental treatment needs (27%), followed by medical conditions/disability (18%), and high caries activity (15%). The use of different techniques for conscious sedation as well as general anaesthesia had also increased. Conclusions. The referrals to paediatric dentistry continue to increase, leading to a heavy work load for the same number of specialists. Thus, the need for more paediatric dentists remains.

    The objectives of this article are to provide a short history of dentistry and dental education in Brazil and to analyze the nature of its development to date. The databases consulted are those provided by the Brazilian Federal Council of Dentistry, Brazilian Ministry of Health, Brazilian Ministry of Education, National Institute of Studies and Educational Research Anísio Teixeira, and Brazilian Institute of Geography and Statistics. Formal dental education in Brazil started in the late nineteenth century with the creation of courses annexed to existing schools of medicine in Rio de Janeiro and Bahia. Today, there are 191 institutions of higher education nationwide granting degrees in dentistry (137 private [71.7 percent] and fifty-four public [28.3 percent]), with a total of 17,157 student positions offered annually. These schools graduate around 10,000 professionals per year-one of the highest rates in the world. Both the distribution of schools of dentistry and of dentists varies among the regions of the country, with the greatest concentrations in major metropolitan centers with high population density, resulting in limited coverage in the more deprived regions. A review of epidemiological data for oral health and distribution of dentists in Brazil indicates that there is a lack of systematic planning for the allocation of the dental workforce and a lack of consideration of regional needs in the development of dental training programs in Brazil today.

    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

    NASA Astrophysics Data System (ADS)

    1991-05-01

    The great interest in the field of laser applications in dentistry provokes the question, if all these new techniques may really fulfill advantages, which are expected after initial in-vitro studies. Whereas laser surgery of soft oral tissues has been developed to a standard method, laser treatment of dental hard tissues and the bone are attended with many unsolved problems. Different laser types, especially pulsed lasers in a wide spectrum of wavelengths have been proofed for dental use. Today neither the excimer lasers, emitting in the far uv-range from 193 to 351 nm, nor the mid-infrared lasers like Nd:YAG (1,064 μm), Ho:YAG (2,1 μm) and Er:YAG (2,96 μm) or the C02-laser (10,6 μm) show mechanism of interaction more carefully and faster than a preparation of teeth with diamond drillers. The laser type with the most precise and considerate treatment effects in the moment is the short pulsed (15 ns) ArF-excimer laser with a wavelength of 193 nm. However this laser type has not yet the effectivity of mechanical instruments and it needs a mirror system to deliver the radiation. Histological results point out, that this laser shows no significant pathological alterations in the adjacent tissues. Another interesting excimer laser, filled with XeCI and emitting at a wavelength of 308 nm has the advantage to be good to deliver through quartz fibers. A little more thermal influence is to be seen according to the longer wavelength. Yet the energy density, necessary to cut dental hard tissues will not be reached with the laser systems available now. Both the pulsed Er:YAG- (2,94 μm, pulse duration 250 s) and the Ho:YAG -laser (2,1 μm, pulse duration 250 μs) have an effective coupling of the laser energy to hydrogeneous tissues, but they do not work sufficient on healthy enamel and dentine. The influence to adjacent healthy tissue is not tolerable, especially in regard of the thermal damage dentine and pulp tissues. Moreover, like the 193 nm ArF-excimer laser

    On 31 May 2013, a line of severe tornadic thunderstorms (the El Reno event) developed during the local afternoon in central Oklahoma, USA. Within range of the Oklahoma Lightning Mapping Array, the evolution of the event can be separated into three distinct periods: an Early period (before 02:00 UTC on 1 June) when the storm consisted of discrete supercells, a Middle period (02:00-05:00 UTC) when the convection began merging into a linear feature and stratiform precipitation developed, and a Late period (after 05:00 UTC) featuring a mature mesoscale convective system (MCS). Each of these periods demonstrated distinct patterns in the large (>100 C km) charge moment change (CMC) lightning that was produced. During the Early period, large-CMC positive cloud-to-ground (+CG) lightning was produced in the convective cores of supercells. These flashes were small in area (typically <500 km2) and were commonly associated with a sloping midlevel positive charge region in the echo overhang on the storm's forward flank. The Middle period featured a population of larger +CMCs (>500 km2, >300 C km) in the developing stratiform, similar to typical sprite-parent lightning in MCSs. During the Late period, convective large CMC +CGs ceased and instead large-CMC negative CGs were produced in and near the MCS convection. These flashes neutralized charge both in convection as well as in adjacent stratiform and anvil precipitation. The results suggest that the CMC metric has potential applications for studying tropospheric weather.

    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.

  13. Discover Dentistry: encouraging wider participation in dentistry using a massive open online course (MOOC).

    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. PMID:26205936

    2013-01-01

    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.

    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.

    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.

    2011-01-01

    Minimal intervention is a key phrase in today's dental practice. Minimal intervention dentistry (MID) focuses on the least invasive treatment options possible in order to minimize tissue loss and patient discomfort. Concentrating mainly on prevention and early intervention of caries, MID's first basic principle is the remineralization of early carious lesions, advocating a biological or therapeutic approach rather than the traditional surgical approach for early surface lesions. One of the key elements of a biological approach is the usage and application of remineralizing agents to tooth structure (enamel and dentin lesions). These agents are part of a new era of dentistry aimed at controlling the demineralization/ remineralization cycle, depending upon the microenvironment around the tooth. This article details the various agents that enhance and/or promote remineralization and discusses their clinical implications.

    The current treatment philosophy is to prevent and detect dental disease at the earliest stage in order to avoid invasive treatment. With the current understanding of the nature of dental disease and its process, the treatment philosophy is now changing to a more conservative approach and the concept of minimal intervention is gaining popularity in modern dentistry throughout the world. It is now established that demineralized but non-cavitated enamel and dentine can be healed and traditional surgical approach of drilling and filling may no longer be necessary as this only treats the symptoms of the disease and not the cause. However, when surgical intervention is indicated, the least invasive techniques such as preventive resin restoration and minimal cavity preparation are utilized. The aim of this article is to give dental professionals an overview of the concepts of minimal intervention dentistry and recent innovations in dental technology in both the diagnosis and treatment of dental caries.

    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

    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. PMID:19079108

    The concept 'Minimally Invasive Dentistry' can be defined as maximal preservation of healthy dental structures. Within cariology, this concept includes the use of all available information and techniques ranging from accurate diagnosis of caries, caries risk assessment and prevention, to technical procedures in repairing restorations. Dentists are currently spending more than half their time replacing old restorations. The main reasons for restoration failures are secondary caries and fractures, factors that are generally not addressed in the technical process of replacing a restoration. Prevailing concepts on minimally invasive dentistry seem to be 'product or technique-motivated', challenging one technique or product with another, rather than focusing on a general concept. New knowledge of caries progression rates has also led to substantial modification of restorative intervention thresholds and further handling of the disease. New diagnostic tools for caries lesion detection, caries risk assessment and focused preventive treatments have decreased the need for early restorative interventions. In parallel to this, new techniques for cutting teeth and removing decay have evolved. This paper focuses on describing minimally invasive dentistry in cariology from a conceptual perspective, relating to clinical caries diagnosis, restorative intervention thresholds and operative procedures, with special reference to survival of tunnel and slot restorations and to repair vs. replacement of defective restorations.

    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. Key words:Forensic identification, DNA, forensic dentistry, rugoscopy, cheiloscopy, saliva. PMID:24790717

    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. PMID:25943026

    Hacking, S A; Khademhosseini, A

    2009-05-01

    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. PMID:19493883

  20. Professional ethics and professional etiquette in dentistry: are they compatible?

    PubMed

    Newbrun, Ernest

    2007-01-01

    In keeping with the theme of this colloquium, two aspects of ethics in dentistry are addressed: its evolution and its future. With respect to its evolution, two examples of changes in the design of clinical trials in dentistry are discussed. These concern the current requirement of informed consent from the subjects in the trial, now taken for granted, but not necessarily observed before 1964. The Vipeholm dental caries study is one example of pre-Helsinki Declaration experimentation. The second example, also drawn from caries research design, concerns the stricture on the use of placebo-controlled trials in the face of a proven drug. For example, the design of clinical trials of fluoride dentifrices has evolved since the mid 1970s. The use of a placebo-inactive control group is no longer acceptable as it would deprive its subjects of a proven caries-preventive agent and would expose its subjects to increased caries risk. While definitions of professional ethics in dentistry may vary, the ADA Code of Ethics includes five principles: patient autonomy ("self-governance"), non-maleficence ("do no harm"), beneficence ("do good"), justice ("fairness") and veracity ("truthfulness"). Professional etiquette refers to the way dentists relate to one another and is governed by the ADA Code of Professional Conduct which expresses specific types of conduct that are either required or prohibited. Sometimes, ethics and etiquette may conflict. The problem of financial issues that conflict with ethical ones is discussed along with the problem of commercialism in the practice of dentistry. Debts from dental school may adversely affect the professional behavior of young dentists, while general dentists might succumb to "goodies" provided by specialists. These often include continuing education courses, gifts, trips, and kickbacks. Specialists may fail to inform patients of improper or poor quality treatment by the referring general practitioner, fearing loss of referrals. Of course

    Pacific Northwest National Laboratory (PNNL) and Redhorse Corporation (Redhorse) conducted an energy audit on the Federal Aviation Administration (FAA) control tower and base building in Reno, Nevada. This report presents the findings of the energy audit team that evaluated construction documents and operating specifications (at the 100% level) and completed a site visit. The focus of the review was to identify measures that could be incorporated into the final design and operating specifications that would result in additional energy savings for the FAA that would not have otherwise occurred.

  3. Inside an Earthquake Swarm: Objective Identification and Analysis of Spatiotemporal Subclusters of the Mogul 2008 Earthquake Swarm in Reno, NV

    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

  5. [Quality assurance in dentistry--past, present and future].

    PubMed

    Vered, Y; Schwartz, N; Babayoff, I

    2003-01-01

    Quality assurance involves the cycle of quality assessment, formal identification of problems, developing a strategy for resolving problems and implementation of changes. Historically, the term "first do not harm" can be considered as the first step in quality assurance. Patients' high expectations from the outcomes of dental treatment, new technology and cost containment changed the perspectives completely. We are facing a new era of an increasing demand for patients' involvement as well as an increasing demand for accountability of the members of the profession. The article describes the development of the issue of quality assurance during the last thirty years and highlights the difficulties encountered by the profession in adjusting the changes due to lack of education, experience, knowledge and absence of a definition for accepted criteria for action. Developing criteria for appropriateness of dental treatment, developing mechanisms for assessing the art of care, development of large data bases and development of consumers' surveys are some of the leading suggestions for future action. The responsibility for quality and quality assurance lies in the hands of the dental profession. Organized dentistry possesses a social and ethical commitment for the society, as well as professional obligation for the members of the profession. Although cost containment gave rise to the issue of quality, quality assurance should not be measured in financial terms, but in terms of accepting responsibility and working for continuous improvement. Steps in the right direction will, hopefully, lead to a better and more efficient utilization of the available resources and will increase the trust of the public in the profession of dentistry. Therefore, organized dentistry should not leave this important issue to be dealt by non-dental professions or commercial organizations. PMID:12674922

    Soon after the discovery of X-rays, it became clear that their use can cause detrimental effects. The field of radiobiology deals with these detrimental effects. In this article, the theoretical concepts of radiobiology relevant to diagnostic X-ray use are presented. The effects of radiation on living tissues, the relationship between dose and effect, and a translation of these effects into the dental application are discussed. X-rays cannot be considered to be harmless even when used at the relatively low doses as in dentistry. If applied with justification and optimization, the risk to the patient will, however, be small.

    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.

    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.

  7. Is dentistry a profession? Part 1. Professionalism defined.

    PubMed

    Welie, Jos V M

    2004-09-01

    Individual dentists and organized dentistry alike invariably claim to be (members of) a profession. This label is cherished because it suggests special social, moral and political status. However, almost every self-respecting occupation nowadays claims to be a profession. Hence, the question arises as to what exactly is meant when dentists claim to be professionals and, more important, whether they can justifiably lay claim to this label. Rather than reviewing the manifold and divergent discussions in the literature about professionalism, the author proposes--in this first of 3 consecutive articles--a definition of the term "profession" that is based on the literal origins of the word. Next, it is argued that a profession arises out of a social contract between the public and a service occupation that professes to give priority to the existential needs of the people served. In the second article, the author deduces several professional responsibilities. The third and final article examines whether and to what extent dentistry fulfills these responsibilities and outlines some future challenges. PMID:15363212

    2014-01-01

    Thanks to sophisticated adhesive techniques in contemporary dentistry, and the development of composite and ceramic materials, it is possible to reproduce a biomimetic match between substitution materials and natural teeth substrates. Biomimetics or bio-emulation allows for the association of two fundamental parameters at the heart of current therapeutic treatments: tissue preservation and adhesion. This contemporary concept makes the retention of the integrity of the maximum amount of dental tissue possible, while offering exceptional clinical longevity, and maximum esthetic results. It permits the conservation of the biological, esthetic, biomechanical and functional properties of enamel and dentin. Today, it is clearly possible to develop preparations allowing for the conservation of the enamel and dentin in order to bond partial restorations in the anterior and posterior sectors therefore limiting, as Professor Urs Belser from Geneva indicates, "the replacement of previous deficient crowns and devitalized teeth whose conservation are justified but whose residual structural state are insufficient for reliable bonding."1 This article not only addresses ceramic adhesive restoration in the anterior area, the ambassadors of biomimetic dentistry, but also highlights the possibility of occasionally integrating one or two restorations at the heart of the smile as a complement to extensive rehabilitations that require more invasive treatment.

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.

  10. 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.

    Saliva is a secretion of the salivary and mucous glands and is of major importance in the maintainance of oral health. Over the last few decades, saliva has been evaluated as a diagnostic fluid in medicine for determining systemic disease markers as well as for monitoring numerous drugs, narcotics, and hormones. The biochemical analysis of saliva is particularly important in dentistry. The estimation of the risk of appearance and diagnosis of disease, monitoring of disease progression, evaluation of therapy efficacy for caries, periodontitis, premalignant and malignant oral lesions, as well as infectious diseases of the oral cavity, can be assessed by analysing different constituents of saliva. Individuals at risk of caries can be identified using tests that determine saliva flow rate, saliva buffer capacity, and colonisation of the oral cavity by cariogenic bacteria. Today, these rapid and simple diagnostic tests are used routinely in caries risk determination. The study and use of saliva-based diagnostics have increased over the last few decades. Clinical testing of saliva shows much promise. However, there is a need for much additional research in this area, before the true clinical value of saliva as a diagnostic fluid in dentistry can be determined.

    2015-01-01

    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. PMID:26464775

    Geriatric dentistry and its instruction are critical in a rapidly ageing population. Japan is the world's fastest-ageing 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 at evaluating 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. Bibliographical data and local information were collected. Descriptive and statistical analyses (Fisher and chi-squared test) were conducted. Japanese dental schools teach geriatric dentistry in 10 geriatric dentistry departments as well as in prosthodontic departments. There were 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 4-year PhD course of study; there is neither a master's degree programme nor a certificate programme 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.

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.

    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.

  17. Application of Low level Lasers in Dentistry (Endodontic)

    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

  18. Social media and dentistry: some reflections on e-professionalism.

    2015-04-24

    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.

  19. Complementary and alternative medicine techniques available for dentistry.

    PubMed

    Andrews, Esther K

    2007-01-01

    Complementary and alternative medicine in dentistry includes various treatment modalities. Many procedures are under scientific investigation to determine effectiveness. Dental patients request CAM therapy in an attempt to save money and to prevent invasive procedures. The Alternative Medical Systems are methods of alternative therapy different from Conventional/Western medicine. Mind-Body Interventions are methods of affecting body functions using prayer, meditation, mental imagery and creativity. Biologically-Based Therapy is the use of substances found in nature to promote healing and wellness. Manipulative and Body-Based Methods are based on the manipulation and/or movement of the body to treat for pain and wellness. Energy Therapy is based on manipulating energy fields of body. CAM procedures may eventually become standard practice after scientific verification of efficacy.

    The 21(st) 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.

    This article has been written jointly by Ingried Morris, a dentist, and Sheila Scott, a marketing consultant. Ingried discusses some of the reasons why her colleagues may reject the marketing approach to dentistry, while Sheila argues that many of these skepticisms are indeed good reasons to embrace the discipline wholeheartedly. We felt that the article posed many questions, often unspoken, that worry a number of the profession who find it difficult harmonizing their perception of a commercial technique--marketing--with treating their patients in a caring profession. The article then goes on to answer those questions and suggests that true marketing is indeed caring, and can only strengthen the quality of clinical care.

    Since 2001, an interdisciplinary project on multimedia education in medicine has been sponsored by the Federal Ministry of Education and Research at the Charité. One part of the project is on dentistry. In the light of the results of a survey of dental students, an Internet-based education management system was created using open-source back-end systems. It supports four didactic levels for editing documentation of patient treatments. Each level corresponds to the learning abilities of the students. The patient documentation is organized to simulate the working methods of a physician or dentist. The system was tested for the first time by students in the summer semester of 2003 and has been used since the winter semester of 2003 as part of the curriculum. PMID:15516095

  3. Glass-ionomer Cements in Restorative Dentistry: A Critical Appraisal.

    PubMed

    2016-01-01

    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.

    This article presents a brief history of dental ceramics and offers perspectives on recent research aimed at the further development of ceramics for clinical use, at their evaluation and selection, and very importantly, their clinical performance. Innovative ceramic materials and ceramics processing strategies that were introduced to restorative dentistry since the early 1980s are discussed. Notable research is highlighted regarding (1) wear of ceramics and opposing enamel, (2) polishability of porcelains, (3) influence of firing history on the thermal expansion of porcelains for metal ceramics, (4) machining and CAD/CAM as fabrication methods for clinical restorations, (5) fit of ceramic restorations, (6) clinical failure mechanisms of all-ceramic prostheses, (7) chemical and thermal strengthening of dental ceramics, (8) intraoral porcelain repair, and (9) criteria for selection of the various ceramics available. It is found that strong scientific and collaborative foundations exist for the continued understanding and improvement of dental ceramic systems.

    There is growing interest in the use of ozone in oral healthcare and the National Institute for Clinical Excellence (NICE) is at present reviewing the evidence for its effectiveness in the management of occlusal and plain surface caries. These are only two of the clinical problems for which ozone can, and has, been used; it has also been employed for a wide variety of other purposes in both dentistry and medicine. This pale blue-coloured gas plays an important role as a natural constituent in the higher layer of the Earth's atmosphere. There is growing evidence that it can be employed as a useful therapeutic agent. This paper reviews its therapeutic uses to date and suggests its possible future clinical applications. Consumer demands for this strong oxidant may increase as the general public becomes increasingly aware of its therapeutic capacity and the non-invasive manner in which it can be administered.

    The "Applied Kinesiology" evolved in the USA is increasingly being used in Central Europe. In this review the development of the method and its practical application in medicine and in dentistry are elucidated. Furthermore the propagation of the method by the International College of Applied Kinesiology (= ICAK) and the "Touch for Health" (=TFH) is described. School medicine's criticism of "Applied Kinesiology" as well as the methodological replies from "Applied Kinesiologists" are outlined. It is important to realise that there is to date a lack of evidence for the effectiveness, validity and reliability of "Applied Kinesiology". The following requirements are thus vital: "Applied Kinesiologists" must develop clear criteria for single subgroups of "Applied Kinesiology", prove the effectiveness of their methods, and explain their findings in agreement with current medical knowledge.

    Reno, Nevada, USA is located in a mountain valley often characterized by very dry conditions, clear sky and red sunsets during the summer season, with rare incursions of monsoonal moisture. This city is subject to moderately strong nocturnal inversions nearly every day in summer. Urban aerosols, wind blown dust, as well as occasional biomass burning smoke from natural and non-natural fires all contribute to the optical depth. Because of its geographical position, drastic changes in weather conditions and variations in aerosol optical properties make Reno an excellent location for evaluating measurements of aerosol optical depth in order to determine particulate air pollution concentration as well as to provide input for models of atmospheric radiation transfer and evaluation of satellite-based aerosol optical sensing measurements. Aerosol optical depth can be calculated by in situ photoacoustic measurements of aerosol light absorption and reciprocal nephelometer scattering coefficients and estimation of aerosol mixing height. LED-based hand-held sun photometers are commonly used as inexpensive instruments for informal networks. However, the LED emission wavelength maximum and bandwidth are higher and narrower than the LED reception wavelength spectrum, necessitating empirical determination of an equivalent wavelength. The manually operated spectrometer and Cimel sun photometer measurements provide the most accurate and precise column aerosol optical depth. This paper makes a comparison between these four instruments for measurements obtained during the summer and fall seasons in order to study how the total and aerosol optical depth change during dry and moist conditions. Ångström exponents of extinction and absorption are also analyzed to provide insight on aerosol size distribution and composition, respectively.

    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.

    Advanced ceramic materials such as zirconia have great potential as substitutes for traditional materials in many biomedical applications. Since the end of the 1990s, the form of partially stabilized zirconia has been promoted as suitable for dental use due to its excellent strength and superior fracture resistance as result of an inherent transformation toughening mechanism. In addition, zirconia bioceramic presents enhanced biocompatibility, low radioactivity, and interesting optical properties. The introduction of computer-aided design/computer-aided manufacturing (CAD/CAM) techniques has increased the general acceptance of zirconia in dentistry. However, some fabrication procedures such as grinding, polishing, sandblasting, heat treatment, and veneering of the fine-grained metastable zirconia microstructures may affect the long-term stability and success of the material by influencing its aging sensitivity. The purpose of this review is to address the evolution of zirconia as a biomaterial; to explore the material's physical, chemical, biological, and optical properties; to describe strengthening procedures; and finally to examine aging, processing, and core/veneer interfacial effects.

    Kitchener, Martin; Mertz, Elizabeth

    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

    2016-01-01

    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.

    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.

    2016-01-01

    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

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

    2016-04-01

    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. PMID:27486290

    With new fiber systems available for 3 μm, Erbium lasers become more interesting for precise tissue ablation in a water environment enabling new application in e.g. dentistry. The dynamics of explosive bubble formation was investigated at 2.78 μm (Er,Cr;YSGG) and 2.94 μm (Er:YAG), in relation to energy (10-50 mJ), pulse length (20-150 μs) and fiber tip shape (flat or taper). The dynamics of exploding and imploding vapor bubbles were captured with high speed imaging (10 - 300 μs range). Increasing the pulse length and energy, the vapor bubble became more elongated with an opaque surface for flat tip fibers. Tapered fibers produced spherical vapor bubbles with an optically transparent surface expected to be more forceful for creating mechanical effects in both hard and soft tissues. There was no significant difference between bubbles formed at 2.78 μm (Er,Cr;YSGG) and 2.94 μm (Er:YAG).

    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.

    The current paper reviews the curing mechanisms found in resin-based materials used in dentistry. Historical aspects of dental products and the associated curing mechanisms are reviewed. In comparison with common industrial procedures, curing methods employed for dental materials are relatively limited because of the need to polymerize quickly in the oral cavity at an ambient temperature. Heat-cure and self-cure dental resins utilize benzoyl peroxide initiator alone with a tertiary amine co-initiator. At present, most dental restorative composites use a camphorquinone-amine complex initiation, visible light-cure, one-component systems, although alternative photoinitiators have been researched and developed. A multiple curing mode in a dual-cure material is a complex combination of various initiation systems. The use of aryl sulfinic acid sodium salt to overcome adverse chemical interactions between simplified adhesives and self- or dual-cure composites is based on another self-cure polymerization mechanism, sulfinic acid-initiated polymerization, proposed by Hagger in 1948. The sodium salt of aryl sulfinic acid reacts with an acidic monomer in simplified adhesives, and is believed to produce radicals. Clinically, it is important to try to optimize the degree of conversion of resin-based materials using proper manipulation and adequate light-curing techniques to ensure the best outcome for materials used to restore teeth.

    Prions are normal proteins present in all mammals, especially in the central nervous system (CNS) and lymphoreticular tissue. Their transformation into a highly infectious molecule gives rise to a group of diseases known as transmissible spongiform encephalopathies (TSEs), which cause vacuolar degeneration of gray matter and produce a fatal neurodegenerative disorder. Prion diseases have attracted considerable attention in recent years, and this review of the literature was designed to determine their implications for dentistry, studying the possibility of cross-transmission in the dental office and describing their oral manifestations. The main oral manifestations are dysphagia, dysarthria, paresthesias, dysesthesias, and dysgeusia. The most frequently involved oral tissues are the trigeminal ganglion, posterior third of the tongue, tonsils, and, much less commonly, alveolar nerves, gingiva, and salivary glands. Although no contagion has been reported in the dental setting to date, prions resist the usual dental sterilization systems and transmission of this type of disease remains a potential risk. It is therefore important for dentists to be aware of these diseases, to identify high-risk patients by obtaining an adequate clinical history, and to know the appropriate procedures to be followed.

    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.

    The hot topic from Capitol Hill in Washington to Capitol Hill in Jefferson City is health care reform. President Clinton started the ball rolling during the campaign in 1992 by including health care reform in his platform. He continued the effort after his election by appointing his wife, Hillary, to chair a task force to present an outline for federal legislation. Since the package was presented to Congress, there has been much discussion, lobbying, and rumoring about the implications of health care reform and what it could mean to all of us as dentists. On the home front, Governor Carnahan has introduced legislation in Missouri to reform the health care system. This effort is known as the Missouri Health Assurance Plan (H.B. 1622). Missouri Dental Association members are vitally concerned about the impact of health care reform on their practice, their taxes, their relationship with their patients and employees, and on their ability to seek out health care services since each member is also a consumer of health care. This article represents answers to some of the questions being asked by MDA members in order that they might be more aware of the activities by the MDA, the ADA, and other levels of organized dentistry relating to health care reform.

    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.

    Aim: To evaluate the sound levels generated in dental clinics of conservative dentistry and endodontics. Material and Methods: A decibel-meter with digital readout was used to measure sound levels at different time intervals at the chairside and at the center of the clinic. Minimum and maximum readings during a 3 min interval were recorded. Results: In the post-graduate (PG) clinic, there was significant difference in noise levels between the chairside (66-81 dB[A]) and the center of the clinic (66-67 dB[A]) at certain times. In the under graduate (UG) clinic, noise levels with suction and either high/slow speed handpieces (67-80 dB[A]) were significantly higher than the center of clinic. Suction alone in the UG clinic (63-75 dB[A]) was significantly quieter than in the PG clinic (69-79 dB[A]). Conclusions: (1) Mean sound levels in the working clinics ranged from 63.0 dB[A] to 81.5 dB[A]. These are within the recommended range for dental equipment. (2) With suction and either low/high speed handpiece combination, the PG clinic was significantly noisier than the UG clinic at several time periods. PMID:23716962

    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

    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.

    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

    Evidence-based dentistry (EBD) is reviewed in depth to underscore the limitations for evidence-based dental materials information that exist at this time. Anecdotal estimates of evidence for dental practice are in the range of 8 percent to 10 percent. While the process of evaluating the literature base for dental evidence began 20 years ago, it was not practical to implement it until high-speed wireless connections, open access to journals, and omnipresent connections via smart phones became a reality. EBD includes five stages of information collection and analysis, starting with a careful definition of a clinical question using the PICO(T) approach. Clinical evidence in randomized control trials is considered the best. Clinical trial perspectives (prospective, cross-sectional, retrospective) and outcome designs (RCTs, SCTs, CCTs, cohort studies, case-control studies) are quite varied. Aggregation techniques (including meta-analyses) allow meaningful combinations of clinical data from trials with similar designs but with fewer rigors. Appraisals attempt to assess the entire evidence base without bias and answer clinical questions. Varying intensities to these approaches, Cochrane Collaboration, ADA-EBD Library, UTHSCSA CATs Library, are used to answer questions. Dental materials evidence from clinical trials is infrequent, short-term, and often not compliant with current guidelines (registration, CONSORT, PRISMA). Reports in current evidence libraries indicate less than 5 percent of evidence is related to restorative dental materials. PMID:24571523

    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 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. PMID:26522631

    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.

    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.

    RENO (Reactor Experiment for Neutrino Oscillation) made a definitive measurement of the smallest neutrino mixing angle θ13 in 2012, based on the disappearance of reactor electron antineutrinos. The experiment has obtained a more precise value of the mixing angle and the first result on neutrino mass difference Δ mee2 from an energy and baseline dependent reactor neutrino disappearance using ∼500 days of data. Based on the ratio of inverse-beta-decay (IBD) prompt spectra measured in two identical far and near detectors, we obtain sin2 ⁡ (2θ13) = 0.082 ± 0.009 (stat .) ± 0.006 (syst .) and | Δ mee2 | = [2.62-0.23+0.21 (stat .)-0.13+0.12 (syst .) ] ×10-3 eV2. An excess of reactor antineutrinos near 5 MeV is observed in the measured prompt spectrum with respect to the most commonly used models. The excess is found to be consistent with coming from reactors. A successful measurement of θ13 is also made in an IBD event sample with a delayed signal of neutron capture on hydrogen. A precise value of θ13 would provide important information on determination of the leptonic CP phase if combined with a result of an accelerator neutrino beam experiment.

    Local anesthetics are frequently administered in dentistry and thus can be expected to be a major source of drug-related complications in the dental office. Additionally, the dentist will more often be confronted with the treatment of risk patients; thus, the incidence of side effects can be expected to rise. In this study, 2731 patients receiving dental anesthesia were evaluated by questionnaire for risk factors, type and dosage of local anesthetic applied, type and duration of treatment, and complications associated with the administration of the local anesthetic. Of all patients, 45.9% had at least one risk factor in their medical histories, with cardiovascular diseases and allergies being the most frequent. The overall incidence of complications was 4.5%. It was significantly higher in risk patients (5.7%) than in nonrisk patients (3.5%). The most frequently observed complications (dizziness, tachycardia, agitation, nausea, tremor) were transient in nature and did not require treatment. Severe complications (seizure, bronchospasm) occurred in only two cases (0.07%). Articaine was found to be administered in over 90% of all dental anesthesias in Germany despite the great variety of local anesthetics available. Articaine 1:100,000 caused more sympathomimetic side effects than did articaine 1:200,000. Additionally, doses of local anesthetics proved not to be strictly determined according to body weight, especially for patients weighing less than 50 kg. In summary, it can be stated that dental local anesthesia can be considered safe. Nevertheless, the incidence of complications due to dental anesthesia can be expected to be further reduced if (a) patients are routinely evaluated for risk factors with an adequate medical history prior to dental treatment, (b) doses of local anesthetics are strictly determined according to body weight, (c) anesthetics with low concentrations of epinephrine are used, and (d) the concept of a differentiated dental anesthesia is applied

  7. Does ART have a place in preservative dentistry?

    Anusavice, K J

    The ART technique consists of hand excavating carious tissue and placing a highly viscous glass ionomer cement as a restoration material and as a sealant. Although the results of several studies are promising, the retention rates of these restorations for primary teeth are not impressive. Materials and methods that yield greater success rates are needed to improve long-term caries management outcomes. In principle, ART should yield outcomes similar to those associated with preservative dentistry, including the potential for minimal surgical intervention, conservation of sound tooth structure, avoidance of pain and need for local anesthetic injections, reduced risk for subsequent endodontics and tooth extraction, and increased survival time of the affected teeth. The ideal direct-filling ART material would be biocompatible and tooth colored; "forgiving" in its handling properties; insensitive to moisture or desiccation; hardenable without special equipment; able to form stable bonds to enamel and dentin; able to seal marginal gaps against bacteria; capable of releasing fluoride or remineralization and antibacterial agents when demineralization is most likely; and resistant to chemical attack. The highly viscous glass ionomer materials currently used for ART meet several of this criteria, though they may be deficient in their ability to seal marginal gaps against bacteria and in their sensitivity to desiccation. Furthermore, although they release fluoride over the lifetime of the restoration, this fluoride release alone may not prevent caries progression in all cases. It is necessary for cases of high caries risk to use chlorhexidine in conjunction with fluoride to achieve caries arrest and remineralization of adjacent areas of the affected teeth. Thus, while the ART technique offers some benefits in restoring function and reducing the rate of caries progression, it is unlikely that current materials will be able to arrest caries progression completely in high

    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. Key words:Vasoconstrictor agents, epinephrine/adverse effects

  9. Minimal intervention dentistry and older patients. Part 1: Risk assessment and caries prevention.

    Ten million people in the UK today are aged over 65. The latest projections estimate that there will be 5 1/2 million more people aged 65 and older in the next 20 years. This projected pattern of population ageing will have profound consequences for dentistry. Minimal intervention dentistry (MID) is a modern evidence-based approach to caries management in dentate patients that uses the 'medical model' whereby disease is controlled by the 'oral physician'. This approach offers considerable benefits over conventional dentistry for older patients. It encourages patients to be responsible for their oral health through the provision of both knowledge and motivation. MID encompasses risk assessment for dental disease, early detection and control of disease processes, and minimally invasive treatment. Clinical Relevance: Risk assessment tools can aid the general dental practitioner and the patient to develop a suitable caries prevention programme for that individual and reduce the need for future operative intervention.

  10. Early dental journalism: a mirror of the development of dentistry as a profession.

    PubMed Central

    The rise of dentistry from a mechanical trade to a profession has often been attributed to the so-called "triumvirate" of organization, education, and journal literature. This essay focuses on one part of the triumvirate, examining the role of journals in the growth of dentistry as a profession, from the appearance of the first journal in 1839 to the publication of the Index to Dental Literature in 1921. Rather than discussing the history of individual titles, it identifies some of the broader issues and problems that confronted early dental journalism. The evolution of dental journals from trade house publications to independent scientific literature mirrored the movement toward professional status in dentistry during the late 19th and early 20th centuries.

    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. PMID:25873990

    PubMed Central

    Stübinger, Stefan

    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

  14. How to deliver a comprehensive preventive dentistry service that dental insurance carriers can underwrite.

    PubMed

    Nizel, A E

    1976-05-01

    The successful practice management of preventive dentistry requires that it be comprehensive and include both chairside and counseling procedures. The chairside clinical procedures are a prophylaxis, topical application of fluorides, application of pit and fissure sealants, and fabrication of mouth-guards and space maintainers. The counseling procedures include plaque control and nutritional guidance. The caries activity test can be used as a means of monitoring excessive sugar intake. It is the responsibility of the dentist to determine the preventive dentistry needs of his patient based on the latter's caries score, periodontal, gingival, and plaque indexes, and diet evaluation. Since patients are prone to certain dental problems during particular age periods, the preventive management procedures must consider the existing and anticipated dental problems on the basis of the patient's age. Each of the preventive services is objective in nature because it involves either chairside or counseling procedures. During the counseling service,worksheets and clinical case notes are kept as part of the patient's dental record. The progressive effectiveness of the home-care preventive dentistry counsling procedures can be measured by scores and indexes. The frequency of repeating the service depends on proven clinical merit and the individual needs of the patient. The delivery of preventive dentistry services can be monitored by dental insurance carriers through peer review of clinical services, data sheets, case notes, a preventive dentistry record, and by patient questionnaire. A method for managing, measuring, and monitoring an objective, comprehensive preventive dentistry service has been presented so that the insurance carrier can underwrite this type of coverage as part of its dental insurance plan.

    Finite element analysis (FEA) has been used extensively to predict the biomechanical performance of various dental implant designs as well as the effect of clinical factors on implant success. By understanding the basic theory, method, application, and limitations of FEA in implant dentistry, the clinician will be better equipped to interpret results of FEA studies and extrapolate these results to clinical situations. This article reviews the current status of FEA applications in implant dentistry and discusses findings from FEA studies in relation to the bone-implant interface, the implant-prosthesis connection, and multiple-implant prostheses.

    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

    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.

    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.

    This article describes a mixed methods conceptual framework for evidence-based dentistry to enhance the curriculum at the University of Alabama at Birmingham School of Dentistry. A focus of recent curriculum reform has been to prepare students to integrate evidence-based dentistry into clinical practice. The authors developed a framework consisting of four conceptual phases to introduce curriculum innovation: 1) exploration of the phenomenon; 2) development of two new instruments; 3) data collection, analysis, outcomes, and evaluation; and 4) application to curricular reform. Eight sequential procedural steps (literature review; focus group discussions; development of themes; survey design; internal review; data collection, analysis, and evaluation; development of recommendations with external review; and implementation of recommendations for curricular enhancement) guided the curricular enhancement. Faculty members supported the concept of teaching evidence-based dentistry to facilitate major curriculum reform, and course directors incorporated evidence-based teaching to prepare scientist-practitioners who meet dental performance standards. The new curriculum implemented following completion of the study is in its third year. Much of its structure is based on evidence-based teaching methodologies, and approximately one-third of the content consists of small groups researching clinical problems with applied science and discussing the findings. The framework described in this article proved useful to guide revision of predoctoral clinical education at one dental school and may be useful in other settings.

    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

    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

    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.

    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

    In 1992, The Faculty of Dentistry of The Karolinska Institute (KI) introduced a dental undergraduate programme specifically for Baltic students. Initiative for this programme came from both the Ministries of Health in Estonia and Latvia and a Member's Bill in the Swedish Committee for Foreign Affairs. The first 10 students were admitted in January 1992, and in 1994, a further 8 students were accepted. The main objective is to train Baltic students according to the Scandinavian model of dental education, in order to facilitate a positive development in dentistry in these countries. Candidates for the programme, dental students in Latvia or Estonia who had completed several preclinical years, were interviewed and tested in their home countries by a Swedish Admissions Committee. The curriculum comprises 7 semesters at the School of Dentistry, and includes complementary courses in basic science, preventive dentistry, and theoretical and practical courses in all fields of clinical dentistry. The students work with increasing independence, treating patients with a great variety of oral diseases and from different age groups. A course in Informatics is central and forms a base for a research-based assignment in collaboration with the respective home universities. The Baltic Programme is the first time KI has designed and implemented a specially tailored dental undergraduate curriculum in English for a selected group of foreign undergraduates. The students have proved to be ambitious and industrious, with very high academic standards. Their results in the written examinations were equal to or better than those of the home students. Of the 9 students who to date have completed the course, all are working as dentists in their respective countries and 6 are associated with their university.

  4. [Pseudo-color filter in two-dimensional imaging in dentistry].

    Most digital systems that are currently used in two-dimensional imaging in dentistry provide opportunities for different image processing filters. One possible means of enhancing digital radiographic image is pseudocoloring (i.e., color conversion of gray-scale images). Recently, this method has become widely used in digital radiology. The human eye is more sensitive to differences in color than to differences in shades of gray. Theoretically, converting a gray scale intensity level of a digital image into colors could enhance the radiographic information. There have been some studies that applied pseudocoloring of digital radiographic images for the detection of caries and periodontal defects. However, thus far, this method failed to show a significantly improved ability for the detection of these lesions. Further investigations are necessary in order to develop specific algorithms that will increase the validity of pseudocoloring in two-dimensional imaging in dentistry.

    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.

    2016-01-01

    Light amplification by stimulated emission of radiation (laser) has been used widely in a range of biomedical and dental applications in recent years. In the field of restorative dentistry, various kinds of lasers have been developed for diagnostic (e.g. caries detection) and operative applications (e.g. tooth ablation, cavity preparation, restorations, bleaching). The main benefits for laser applications are patient comfort, pain relief and better results for specific applications. Major concerns for using dental lasers frequently are high cost, need for specialized training and sensitivity of the technique, thereby compromising its usefulness particularly in developing countries. The main aim of this paper is to evaluate and summarize the applications of lasers in restorative dentistry, including a comparison of the applications of lasers for major restorative dental procedures and conventional clinical approaches. A remarkable increase in the use of lasers for dental application is expected in the near future. PMID:26642047

    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.

    Provisional restorations fulfill many functions in restorative dentistry. Quality provisional restorations can provide the clinician, the patient, and the laboratory technician much valuable information prior to fabrication of the definitive restoration. Such diagnostic provisional restorations fabricated with acrylic resin are easily adjusted and modified until both esthetic and functional results are approved by the patient. Once this approval has been obtained, the definitive restorations can be fabricated with confidence, using the esthetic form of the provisional restorations as a blueprint.

    Artificially induced demineralization of enamel is frequently used during laboratory tests, particularly in minimally invasive dentistry. The aim of this study was to analyze demineralization techniques of hard tooth tissue applicable in the research of materials in minimally invasive dentistry. The most important factor taken into consideration when designing a method is to make a model as closely similar to the natural environment of the human oral cavity as it is possible. In vitro models allow us to maintain stability and control over the environment and guarantee repeatability of the results. There are main models to produce dental caries outside of the body. The first model is chemical and it uses acids. It is simplified and reflects the actual environment of the oral cavity to a lesser degree. The second model is biological and it is more accurate as it uses microorganisms which build the dental plaque. Among in vitro protocols are also used pH-cycling models. Based on the available literature, it was found that bovine teeth and human teeth with demineralization diagnosed while still inside the oral cavity are the most frequently used kind of specimens in research conducted with use of the chemical model. Not a single case of use of the biological and pH-cycling models were found in the available literature related to the research of infiltrants in minimally invasive dentistry.

    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 purpose of the present study was to evaluate the clinical success and patient satisfaction when dental implant-retained mandibular overdentures are placed and restored by novice general dentistry residents. A total of 50 subjects who were dissatisfied with their mandibular complete dentures were enrolled in the study. Two dental implants were placed in the anterior mandible between the mental foramina by novice general dentistry residents under the direct supervision of the principal investigator. The resident attached the denture to the implants 3 to 4 months later using locator attachments. The implant success rate was determined by measuring bone loss, mobility, pocket probing depth, and gingival and plaque indices. Subjects were asked to complete a satisfaction questionnaire with the prosthesis at 3 months, 1 year, and 2 years after overdenture delivery. A total of 100 implants were placed in the 50 study subjects. Of these, 2 implants were lost in 1 subject, and 1 subject died due to unrelated causes. Of the 48 remaining subjects, 45 have had their implants restored with overdentures. The subjects' overall satisfaction with fit and ability to chew hard foods with their mandibular overdentures improved significantly (P < .05) following the denture attachment to the dental implants. We conclude that novice general dentistry residents can successfully place mandibular implants and restore them with overdentures under direct supervision, subsequently enhancing the subjects' satisfaction with their mandibular dentures.

    The role of fluoride to reduce demineralization and enhance remineralization of dental hard tissue has been well documented. Different forms of fluoride solutions have been topically used in dentistry as prophylactic agents against tooth decay. In the recent past, metal fluorides, especially titanium tetrafluoride, have become popular in the fraternity of dental research due to their unique interaction with dental hard tissue. Many studies on titanium tetrafluoride, with positive and negative conclusions, have been published in many research journals. This gives the reader a plethora of inconclusive results with one study neutralizing the outcome of other, which confuses us regarding the present status of titanium tetrafluoride in the field of dentistry. This is an endeavor to organize and present the various studies of this unique compound, to provide us with a lucid overall review of its versatile potential application in dentistry, along with its fallacy/drawbacks. We have discussed its role as a cariostatic agent, pit and fissure sealant, tooth desensitizer, against dental erosion, as a root canal irrigant and others. PMID:21814345

    The role that Lois played at the NIDR and the IADR as an advocate for biopsychosocial research in dentistry cannot be underestimated and remains one of her most cherished and lasting legacies. First, she has steadfastly maintained her vision for dentistry as a major health discipline that continues to mature toward acceptance of responsibility for every aspect of the impact that oral disease could have on the health and welfare of its patients. Next, she has been an exemplary role model as a rigorous social scientist, simultaneously advocating that such research be interdisciplinary and collaborative while reflecting only the highest standards of excellence for research from the social, biologic, and clinical sciences. Through her administrative leadership skills, she has encouraged such a research mission to be incorporated into the long-range planning of the NIDCR, IADR, FDI, and ADA. Such is the esteem in which she is held that respected social scientists have been attracted to dentistry, persuaded by her vision and drawn by her science. For several decades, thanks to Lois as the primary role model, these scientists have been able to develop their own careers and research interests while bringing cadres of new scientists similarly committed to the broadest and deepest understanding of dental and orofacial growth and development and the prevention and management of dental and orofacial conditions as those processes emerge in peoples around the world.

    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 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.

    Research in the context of the dental school has traditionally been focused on institutional/faculty accomplishments and generating new knowledge to benefit the profession. Only recently have significant efforts been made to expand the overall research programming into the formal dental curriculum, to provide students with a baseline exposure to the research and critical thinking processes, encourage evidence-based decision-making, and stimulate interest in academic/research careers. Various approaches to curriculum reform and the establishment of multiple levels of student research opportunities are now part of the educational fabric of many dental schools worldwide. Many of the preliminary reports regarding the success and vitality of these programs have used outcomes measures and metrics that emphasize cultural changes within institutions, student research productivity, and student career preferences after graduation. However, there have not been any reports from long-standing programs (a minimum of 25 years of cumulative data) that describe dental school graduates who have had the benefit of research/training experiences during their dental education. The University of Manitoba Faculty of Dentistry initiated a BSc Dent program in 1980 that awarded a formal degree for significant research experiences taking place within the laboratories of the Faculty-based researchers and has continued to develop and expand this program. The success of the program has been demonstrated by the continued and increasing demands for entry, the academic achievements of the graduates, and the numbers of graduates who have completed advanced education/training programs or returned to the Faculty as instructors. Analysis of our long-term data validates many recent hypotheses and short-term observations regarding the benefits of dental student research programs. This information may be useful in the design and implementation of dental student research programs at other dental schools.

    2016-06-01

    In recent years in the United States, there has been heightened interest in offering clinical licensure examination (CLE) alternatives to the live patient-based method in dentistry. Fueled by ethical concerns of faculty members at the University of Minnesota School of Dentistry, the state of Minnesota's Board of Dentistry approved a motion in 2009 to provide two CLE options to the school's future predoctoral graduates: a patient-based one, administered by the Central Regional Dental Testing Service, and a non-patient-based one administered by the National Dental Examining Board of Canada (NDEB). The validity of the NDEB written exam and objective structured clinical exam (OSCE) has been verified in a multi-year study. Via five-option, one-best-answer, multiple-choice questions in the written exam and extended match questions with up to 15 answer options in the station-based OSCE, competent candidates are distinguished from those who are incompetent in their didactic knowledge and clinical critical thinking and judgment across all dental disciplines. The action had the additional effects of furthering participation of Minnesota Board of Dentistry members in the University of Minnesota School of Dentistry's competency-based curriculum, of involving the school's faculty in NDEB item development workshops, and, beginning in 2018, of no longer permitting the patient-based CLE option on site. The aim of this article is to describe how this change came about and its effects. PMID:27251345

    2013-12-31

    Throughout the world there is considerable variation in the techniques used to manage anxious dental patients requiring treatment. Traditionally anxious or phobic dental patients may have been sent for general anaesthesia to allow dental treatment be undertaken. While this is still the case for the more invasive oral surgical procedures, such as wisdom teeth extraction, sedation in general dentistry is becoming more popular. Various sedation techniques using many different anaesthetic agents have gained considerable popularity over the past 30 years. While the practice of sedating patients for dental procedures is invaluable in the management of suitably assessed patients, patient safety must always be the primary concern. Medical, dental and psychosocial considerations must be taken into account when evaluating the patient need and the patient suitability for sedation or general anaesthesia. The regulations that govern the practice of dental sedation vary throughout the world, in particular regarding the techniques used and the training necessary for dental practitioners to sedate patients. It is necessary for medical and dental practitioners to be up to date on current practice to ensure standards of practice, competence and safety throughout our profession. This article, the first in a two-part series, will provide information to practitioners on the practice of sedation in dentistry, the circumstances where it may be appropriate instead of general anaesthesia and the risks involved with sedation. It will also discuss the specific training and qualifications required for dental practitioners to provide sedation. The second article in this series will outline the different techniques used to administer inhalation, oral and intravenous sedation in dentistry and will focus on specific methods that are practiced.

    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.

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.

    This study investigated the career choice and aspirations of early phase dental students in the four dental schools in South Africa, namely the University of the Western Cape (UWC), University of the Witwatersrand (Wits), University of Limpopo (Medunsa) and University of Pretoria (UP). Willing participants completed a self-administered questionnaire (n=184). Motivations for entering a dentistry programme were similar across race and university, with wanting a secure job most often stated as an important factor. For a third of respondents, dentistry was not a first choice. Amongst the White students, it was a first choice for 82% compared with 59% amongst Black Africans. Expected income five-years after graduation also differed significantly across race and university, with White and UP students expecting to earn considerably higher than the others. About 36% of students were concerned about the levels of personal debt related to studying, with the White and Asian students less concerned. Those who expected lower levels of income from the profession were more concerned about personal debts. Most students planned to enter general dental practice (GDP) after community service, almost all White and Wits students expressed this intention, compared with only 35% of Black Africans and 39% of Medunsa students. Orthodontics and Maxillofacial & Oral Surgery were the most popular specialities of choice. The professional attribute "Has a friendly manner and good relationship with patients" was ranked high most often. In conclusion, career advice may not need to be tailored differently for the different racial groups. There is however a need for further investigations on how to address the concerns of financial security which may be realised by the practice of dentistry, and in particular the racial disparities observed in expectations of the profession. This study further highlights the need for government financial assistance for students from under-represented groups.

    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.

    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 need for scientific evidence should be the basis of clinical practice. The field of restorative dentistry and endodontics is evolving at a rapid pace, with the introduction of several materials, instruments, and equipments. However, there is minimal information of their relevance in clinical practice. On the one hand, material and laboratory research is critical, however; its translation into clinical practice is not being substantiated enough with clinical research. This four part review series focuses on methods to improve evidence-based practice, by improving methods to integrate laboratory and clinical research.

    The need for universal access to health care and the failure of the pedagogical model centered on only the transmission of knowledge has led to changes in the training of health professionals. The aim of this study was to provide a new alternative for evaluation of Dentistry courses based on the National Curriculum Guidelines (NCG) of the area. For this, a logical model was formulated on the need for training in the oral health pathway which allowed for the construction of a criteria matrix, validated by Delphi consensus technique and modified by the participation of 33 "experts." The matrix dimensions presented as a pedagogical approach the profile of graduates, the teaching-service integration and orientation of health care. The detailing of these dimensions into sub-dimensions and of measurable criteria allowed for deepening structural elements of the NCG unexplored in other studies evaluating undergraduate courses in Dentistry. The final instrument proposed in this study is differentiated alternative assessment training, for both dentists and other professionals, considering that the NCG of all healthcare courses provide for the training focused on the health needs of the population, integrated to Unified Health System (SUS) and based on student-centered learning.

    Test items created for dentistry examinations are often individually written by content experts. This approach to item development is expensive because it requires the time and effort of many content experts but yields relatively few items. The aim of this study was to describe and illustrate how items can be generated using a systematic approach. Automatic item generation (AIG) is an alternative method that allows a small number of content experts to produce large numbers of items by integrating their domain expertise with computer technology. This article describes and illustrates how three modeling approaches to item content-item cloning, cognitive modeling, and image-anchored modeling-can be used to generate large numbers of multiple-choice test items for examinations in dentistry. Test items can be generated by combining the expertise of two content specialists with technology supported by AIG. A total of 5,467 new items were created during this study. From substitution of item content, to modeling appropriate responses based upon a cognitive model of correct responses, to generating items linked to specific graphical findings, AIG has the potential for meeting increasing demands for test items. Further, the methods described in this study can be generalized and applied to many other item types. Future research applications for AIG in dental education are discussed. PMID:26933110

    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.

    Sports dentistry has been considered a prominent area of dentistry because dental health can limit the abilities of athletes, both professional and nonprofessional, in their training and competition. Dental decay is associated with the frequent use of carbohydrates, recommended as an energy source for exercise. Strong indications exist regarding the possibility to use saliva as a performance determinant and for evaluation and prescription of physical activity. This study evaluated the salivary profiles (pH, flow rate, mutans streptococci and Lactobacillus counts) and decayed, missing, and filled teeth of 18 female soccer players (13 to 19 years old) of the Olympic Training and Research Center of São Paulo, before and after a training session. The salivary flow rate presented a significant reduction after training; however, there was no significant alteration in pH. Fifty percent of the players presented 10(5) to 10(6) mutans streptococci, and 66% presented 10(3) Lactobacillus. Several salivary components protect against microorganisms that cause superior respiratory tract infections (common in athletes), as well as participating in the remineralization mechanism during cariogenic challenges. Thus, due to the salivary flow rate reduction in this population with a high number of cariogenic microorganisms, noncariogenic drink ingestion at regular intervals and maintenance of hydration levels during training, are suggested.

    Summary This study aims to critically summarize the literature about nano-hydroxyapatite. The purpose of this work is to analyze the benefits of using nano-hydroxyapatite in dentistry, especially for its preventive, restorative and regenerative applications. We also provide an overview of new dental materials, still experimental, which contain the nano-hydroxyapatite in its nano-crystalline form. Hydroxyapatite is one of the most studied biomaterials in the medical field for its proven biocompatibility and for being the main constituent of the mineral part of bone and teeth. In terms of restorative and preventive dentistry, nano-hydroxyapatite has significant remineralizing effects on initial enamel lesions, certainly superior to conventional fluoride, and good results on the sensitivity of the teeth. The nano-HA has also been used as an additive material, in order to improve already existing and widely used dental materials, in the restorative field (experimental addition to conventional glass ionomer cements, that has led to significant improvements in their mechanical properties). Because of its unique properties, such as the ability to chemically bond to bone, to not induce toxicity or inflammation and to stimulate bone growth through a direct action on osteoblasts, nano-HA has been widely used in periodontology and in oral and maxillofacial surgery. Its use in oral implantology, however, is a widely used practice established for years, as this substance has excellent osteoinductive capacity and improves bone-to-implant integration.

    The aim of this paper is to report the views of academic dentists about careers in academic dentistry assessed by method of a postal questionnaire survey. The subjects of the survey were dentists in academic posts in the United Kingdom. The incentives in pursuing an academic career which respondents rated most highly were the opportunity to teach and the variety of work in an academic career. The greatest disincentives were competing pressures from service work, teaching and research, and the difficulty of getting research grants. Many would like to spend more time on research and less on service work and teaching. The length of time required for training, and the quality of training, was a concern, particularly for junior academics. Most respondents rated the enjoyment of their job highly but scored much lower on satisfaction with the time their job left for domestic and leisure activities. By contrast with academic medicine, in academic dentistry there is typically greater emphasis on teaching and less on research. In conclusion, the balance of activities in academic posts, particularly between service work, teaching and research, needs to be regularly reviewed. The development of a more structured training programme for junior academics, which does not disadvantage academic dentists when compared with their NHS colleagues, may be required.

    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.

    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.

    This cross-sectional study aimed at evaluating the abstracts of all articles published in the 'Jornal Brasileiro de Odontopediatria e Odontologia do Bebê' in order to collect data on the study design used, the most researched topics and the Brazilian states with the highest scientific production. Copies were made of the abstracts of each article, totaling 572 abstracts. Data categorization was done by two trained and independent reviewers. The results showed that the most used study design were case report (33%) and cross-sectional study (30%). On the other hand, there were only 2.5% of randomized clinical trials and no systematic review or meta-analysis. The most researched topics were cariology (15%) and restorative dentistry / dental materials (10%). The state with the greatest number of publications was São Paulo (40%), followed by Rio de Janeiro (17%). It was concluded that the majority of the articles published referred to studies with a low potential to establish scientific evidence, indicating a need for conducting research based on better quality methodology. Moreover, it was found that the assessed literature reflected the trends observed in the clinical practice of Pediatric Dentistry in Brazil.

    Exposure among dentistry students has not been assessed or regulated in Mexico. This work assessed the average exposure of 35 dentistry students during their training with the aid of LiF:Mg,Cu,P+PTFE thermoluminescent dosimeters. For the students in the roles of dentist and observers, maximum accumulated equivalent dose obtained was 2.59±0.11 and 4.64±0.39 mSv, respectively. Students in the role as patients received a maximum accumulated effective dose of 28.41±0.31 mSv. If compared to occupational dose limits, this latter value is 56% of the recommended value of 50 mSv in any year. It was found that in all cases, values of equivalent dose to the women breasts were equal to the background dose. Results are discussed and compared to previous published work. Suggested recommendations were given to authorities in order to minimize exposure of the students in the role as patients.

    Objective: The aim of the this study was to evaluate the perception of smile esthetics and alterations in cases of gingival plastic surgery for correction of a gummy smile, by means of alterations in smile photograph among dentistry degree students. Materials and Methods: A frontal smile photograph of a 40-year-old woman having normal occlusion was used with diverse compositions of gingival exposure level and crown length of maxillary teeth. The eight photographs were evaluated by 216 dentistry students in five class groups (1st, 2nd, 3rd, 4th and 5th classes). Results: The results revealed that almost all of the class’ students perceived differences between images, additionally, the highest percentage of students that answered “no difference” was 12% at 1st class’ students. 1st and 2nd class’ students most liked photograph which is 2.5 mm gingival display and 3rd class students liked two different photographs which are 2.5 mm gingival display and 2 mm gingival display whereas 4th class students preferred two different photographs which are 1.5 mm gingival display and 1 mm gingival display, 5th class students preferred photograph which is 1.5 mm gingival display as the most. Conclusion: Esthetic perception of smile improve as a student passes to higher study classes in terms of gingival exposure. The harmonious display of gingiva exhibits an important effect in the smile esthetics rather than reduced or excessive display. PMID:27403061

    Nanotechnologies are predicted to revolutionize: (a) the control over materials properties at ultrafine scales; and (b) the sensitivity of tools and devices applied in various scientific and technological fields. In this short review, we argue that dentistry will be no exception to this trend. Here, we present a dynamic view of dental tissues, an adoption of which may lead to finer, more effective and minimally invasive reparation approaches. By doing so, we aim at providing insights into some of the breakthroughs relevant to understanding the genesis of dental tissues at the nanostructural level or generating dental materials with nanoscale critical boundaries. The lineage of the progress of dental science, including the projected path along the presumed nanotechnological direction of research and clinical application is mentioned too. We conclude by claiming that dentistry should follow the trend of probing matter at nanoscale that currently dominates both materials and biological sciences in order to improve on the research strategies and clinical techniques that have traditionally rested on mechanistic assumptions.

    The aims of this study were to identify the level of interexaminer agreement among preclinical operative dentistry faculty members when grading Class II preparations performed by first-year dental students; to develop discrimination exercises for specific preparation components where interexaminer agreement was poor; and to evaluate if the discrimination exercises were able to improve inter- and intraexaminer agreement. In the preliminary phase of this study, 13 components of 32 Class II cavity preparations were assessed by eight course faculty members at one U.S. dental school. Analysis of average interexaminer agreement on these components revealed that six were below 60%. These were proximal contact clearance, retention groove placement, retention groove depth, preparation walls, preparation margins, and preparation toilet/debris. A 30-minute calibration session was subsequently developed to provide discrimination exercises utilizing 3-D models and digital images of various levels of student performance for five of the six components. Immediately following calibration, the course faculty assessed the same 32 preparations (Phase I) followed by a delayed assessment without calibration (Phase II) approximately six months later. The results showed that overall interexaminer reliability improved after calibration. Although there was a decline in interexaminer reliability after an interval of six months (Phase II), the degree of variation among examiners was lower than in the preliminary assessment. These findings support the use of discrimination exercises for preclinical operative dentistry course faculty to increase interexaminer agreement and thereby improve the consistency of faculty-student communication.

Two follow-up contacts were made to increase the response rate. A total of 49 surveys were returned for a response rate of 86%. The responding program directors reported that their programs' patient pools had declined in number and had changed in character with more diversity and fewer procedures. They attributed the changes to competition, cost, and location of the dental school. The respondents reported that community-based dental education clinical sites continued to provide additional service experiences for dental students, with contributions varying by the nature of the site. A large number of the respondents felt that their graduates lacked some basic pediatric dentistry clinical skills and were not ready for independent practice with children. The results of this study suggest that the predoctoral pediatric dentistry patient pool has changed and general dentists may be graduating with inadequate experiences to practice dentistry for children.

    People with disability are subject to inequality in oral health both in terms of prevalence of disease and unmet healthcare needs. Over 18% of the global population is living with moderate to severe functional problems related to disability, and a large proportion of these persons will require Special Care Dentistry at some point in their lifetime. It is estimated that 90% of people requiring Special Care Dentistry should be able to access treatment in a local, primary care setting. Provision of such primary care is only possible through the education and training of dentists. The literature suggests that it is vital for the dental team to develop the necessary skills and gain experience treating people with special needs in order to ensure access to the provision of oral health care. Education in Special Care Dentistry worldwide might be improved by the development of a recognised academic and clinical discipline and by providing international curricula guidelines based on the International Classification of Functioning, Disability and Health (ICF, WHO). This article aims to discuss the role and value of promoting and harmonising education in Special Care Dentistry as a means of reducing inequalities in oral health. PMID:23050499

    The esthetic and functional rehabilitation of worn anterior teeth should follow the principles of minimally invasive dentistry. When dental wear occurs at both the facial and palatal surfaces, the sandwich approach of reconstructing eroded anterior teeth with palatal followed by facial veneers is a straightforward treatment that preserves sound dental structure.

    Dental records are essential for dentist and patient protection, and its maintenance is considered an ethical and legal obligation of the dentist: Ethical, because it satisfies the duty of care that the dentist has toward his patient and legal, as it is an investment for future protection against medico-legal complications. In addition to its legal and ethical role, the dental fraternity in India is slowly waking up to its importance in forensic dentistry. Dentists could play a vital role in assisting forensic investigators in providing information that would help in the identification of perpetrators or victims of crime and natural or manmade disaster situations. This information would be easily available and accessible through well-maintained patient records under dental care. PMID:24695875
