Dental problems are a common complaint in emergency departments in the United States. There are a wide variety of dental issues addressed in emergency department visits such as dental caries, loose teeth, dental trauma, gingival infections, and dry socket syndrome. Review of the most common dental blocks and dental procedures will allow the practitioner the opportunity to make the patient more comfortable and reduce the amount of analgesia the patient will need upon discharge. Familiarity with the dental equipment, tooth, and mouth anatomy will help prepare the practitioner for to perform these dental procedures.

We present here the first in vivo optical coherence tomography (OCT) images of human dental tissue. A novel dental optical coherence tomography system has been developed. This system incorporates the interferometer sample arm and transverse scanning optics into a handpiece that can be used intraorally to image human dental tissues. The average imaging depth of this system varied from 3 mm in hard tissues to 1.5 mm in soft tissues. We discuss the application of this imaging system for dentistry and illustrate the potential of our dental OCT system for diagnosis of periodontal disease, detection of caries, and evaluation of dental restorations.

Dental sepsis or periapical abscess formation constitutes a large percentage of dental conditions that afflict horses. Dental sepsis occurs when the pulp chamber of the tooth is exposed to the oral cavity or external environment, allowing bacterial localization with resulting infection. Although acute, primary, septic pulpitis in horses is rare, dental sepsis often results from colonization of the pulp chamber with pathogenic bacteria secondary to maleruption or impaction of teeth with secondary alveolar bone lysis, primary fractures of the tooth, mandible, or maxilla, periodontal disease, or infundibular necrosis. The sequela to pulpal infection are extensions into the periradicular tissues and mandibular or maxillary periapical abscess formation.

Dental implants restore function to near normal in partially or completely edentulous patients. A root-form implant is the most frequently used type of dental implant today. The basis for dental implants is osseointegration, in which osteoblasts grow and directly integrate with the surface of titanium posts surgically embedded into the jaw. Radiologic assessment is critical in the preoperative evaluation of the dental implant patient, as the exact height, width, and contour of the alveolar ridge must be determined. Moreover, the precise locations of the maxillary sinuses and mandibular canals, as well as their relationships to the site of implant surgery must be ascertained. As such, radiologists must be familiar with implant design and surgical placement, as well as augmentation procedures utilized in those patients with insufficient bone in the maxilla and mandible to support dental implants.

This chapter describes the applications of OCT for imaging in vivo dental and oral tissue. The oral cavity is a diverse environment that includes oral mucosa, gingival tissues, teeth and their supporting structures. Because OCT can image both hard and soft tissues of the oral cavity at high resolution, it offers the unique capacity to identity dental disease before destructive changes have progressed. OCT images depict clinically important anatomical features such as the location of soft tissue attachments, morphological changes in gingival tissue, tooth decay, enamel thickness and decay, as well as the structural integrity of dental restorations. OCT imaging allows for earlier intervention than is possible with current diagnostic modalities.

Background An inverse relationship between dental calculus mineralization and dental caries demineralization on teeth has been noted in some studies. Dental calculus may even form superficial layers over existing dental caries and arrest their progression, but this phenomenon has been only rarely documented and infrequently considered in the field of Cariology. To further assess the occurrence of dental calculus arrest of dental caries, this study evaluated a large number of extracted human teeth for the presence and location of dental caries, dental calculus, and dental plaque biofilms. Materials and methods A total of 1,200 teeth were preserved in 10% buffered formal saline, and viewed while moist by a single experienced examiner using a research stereomicroscope at 15-25× magnification. Representative teeth were sectioned and photographed, and their dental plaque biofilms subjected to gram-stain examination with light microscopy at 100× magnification. Results Dental calculus was observed on 1,140 (95%) of the extracted human teeth, and no dental carious lesions were found underlying dental calculus-covered surfaces on 1,139 of these teeth. However, dental calculus arrest of dental caries was found on one (0.54%) of 187 evaluated teeth that presented with unrestored proximal enamel caries. On the distal surface of a maxillary premolar tooth, dental calculus mineralization filled the outer surface cavitation of an incipient dental caries lesion. The dental calculus-covered carious lesion extended only slightly into enamel, and exhibited a brown pigmentation characteristic of inactive or arrested dental caries. In contrast, the tooth's mesial surface, without a superficial layer of dental calculus, had a large carious lesion going through enamel and deep into dentin. Conclusions These observations further document the potential protective effects of dental calculus mineralization against dental caries. PMID:27446993

Dental caries is one of the most prevalent diseases afflicting mankind. It reached a peak in the 1950s but has been declining drastically in recent years in children and young adults. This article describes the three contributing factors in dental caries: microbial plaque, tooth susceptibility, and diet, and discusses practical preventive measures which help to reduce caries incidence. Some of these, such as vaccines and antimicrobial varnishes, are still in the research stages, while others, such as sucrose substitutes, low-calorie sweeteners, and limitation of frequency of sugar snacks are well established and can be promoted by family physicians.

This paper relates recent modes of dental practice to changes that the public and government are likely to ask the health care professions to make in the future. As usual they are asking for the best of all worlds. First, that we maintain the clinical model to the highest standards of personal dental care based and tested against the best research at our disposal, whilst we ensure there is no reduction in the high technical standards for which british dentists have a reputation. Second, that the profession is required to consider ways of providing care on the medicosocial model for the whole community at an economic level the country will afford. The broad changes in dental education have been reviewed, from the technical apprenticeship to the establishment of strong university departments in teaching hospitals. The importance of a sound biomedical foundation and of research both to education and the credibility of dental practice as a primary health care profession is stressed if the profession is to retain its position as a sister to medicine and not slide down to that of a technical ancillary.

Ten years have passed since the first articles appeared in this new field. The qualities of the laser light together with the need of contactless 3-D measurements for different dental purposes seemed to be extremely promising, but still just a few scientists have used the method and mostly for laboratory studies. For some reason there has been a preponderance for orthodontic measurements. This seems to be a bit peculiar from holographic view compared with measurements for engineering purposes, which usually are made on metals. So naturally holography can become a clinical tool for measurements in the field of fixed bridges, removable partial dentures and implants. One of the problems is that the need for holography in dental research must be fulfilled in collaboration with physicists. Only a two-way communication during an entire experiment can balance both technical and odontological demands and thus give practical and clinical important results. The need for an easy way of handling the evaluation to get all required information is another problem and of course the holographic equipment must be converted to a box easy to handle for everyone. At last the position of dental holography today is going to be carefully examined together with an attempt to look into the hopefully exciting and not to utopic future for this research field.

Dental caries continues to be the most prevalent bacteria-mediated non-contagious disease of humankind. Dental professionals assert the disease can be explained by poor oral hygiene and a diet rich in sugars but this does not account for caries free individuals exposed to the same risk factors. In order to test the hypothesis that amount of amelogenin during enamel development can influence caries susceptibility, we generated multiple strains of mice with varying levels of available amelogenin during dental development. Mechanical tests showed that dental enamel developed with less amelogenin is "weaker" while the dental enamel of animals over-expressing amelogenin appears to be more resistant to acid dissolution.

This article describes Colombia's development of formal dentistry, its dental school system, curriculum, and dental licensure, and current issues in oral health care. In 1969, there were only 4 dental schools in Colombia; at this writing there are 21. Five dental schools are public and the other 16 are private. Nearly all classes are conducted in Spanish. Undergraduate pre-dental coursework is not a prerequisite for dental school in Colombia. To obtain licensure, Colombian dental students must complete 5 years of study in dental school, earn a diploma, and work for the government for 1 year. There are approximately 41,400 dentists in Colombia, and the number is increasing quickly. However, the unemployment rate among dentists is very high, even though graduation from dental school is extremely difficult. Although the 1,100:1 ratio of citizens to dentists is considered satisfactory, access to dental care is limited due to the high rate of poverty. PMID:20339245

Forensic dental identification specialists are typically the last conventional option for postmortem identification. Forensic dental identification is most often accomplished by comparing radiographs of the decedent's teeth with the dental radiographs obtained from the dentist of the suspected victim. Unfortunately, antemortem dental radiographs are not always available. When presented with this challenge, the authors of this article have been successful in completing identifications using means other than dental radiographic comparison.

Teeth have long been used as indicators of primate ecology. Early work focused on the links between dental morphology, diet, and behavior, with more recent years emphasizing dental wear, microstructure, development, and biogeochemistry, to understand primate ecology. Our study of Lemur catta at the Beza Mahafaly Special Reserve, Madagascar, has revealed an unusual pattern of severe tooth wear and frequent tooth loss, primarily the result of consuming a fallback food for which these primates are not dentally adapted. Interpreting these data was only possible by combining our areas of expertise (dental anatomy [FC] and primate ecology [MS]). By integrating theoretical, methodological, and applied aspects of both areas of research, we adopted the term "dental ecology"-defined as the broad study of how teeth respond to the environment. Specifically, we view dental ecology as an interpretive framework using teeth as a vehicle for understanding an organism's ecology, which builds upon earlier work, but creates a new synthesis of anatomy and ecology that is only possible with detailed knowledge of living primates. This framework includes (1) identifying patterns of dental pathology and tooth use-wear, within the context of feeding ecology, behavior, habitat variation, and anthropogenic change, (2) assessing ways in which dental development and biogeochemical signals can reflect habitat, environmental change and/or stress, and (3) how dental microstructure and macro-morphology are adapted to, and reflect feeding ecology. Here we define dental ecology, provide a short summary of the development of this perspective, and place our new work into this context.

This article reports on the development of the dental hygiene profession in Slovakia from a global perspective. The aim is to inform about current developments and to examine, how access to qualified dental hygiene care might be improved and how professional challenges might be met. For an international study on dental hygiene, secondary source data were obtained from members of the House of Delegates of the International Federation of Dental Hygienists (IFDH) or by fax and e-mail from experts involved in the national professional and educational organization of dental hygiene in non-IFDH member countries, such as Slovakia. Responses were followed-up by interviews, e-mail correspondence, visits to international universities, and a review of supporting studies and reference literature. Results show that the introduction of dental hygiene in Slovakia in 1992 was inspired by the delivery of preventive care in Switzerland. Initiating local dentists and dental hygienists strive to attain a high educational level, equitable to that of countries in which dental hygiene has an established tradition of high quality care. Low access to qualified dental hygiene care may be a result of insufficient funding for preventive services, social and cultural lack of awareness of the benefits of preventive care, and of limitations inherent in the legal constraints preventing unsupervised dental hygiene practice. These may be a result of gender politics affecting a female-dominated profession and of a perception that dental hygiene is auxiliary to dental care. International comparison show that of all Eastern European countries, the dental hygiene profession appears most advanced in Slovakia. This is expressed in high evidence-based academic goals, in extensive work with international consultants from the Netherlands and Switzerland, in annual congresses of high professional quality, and in the establishment of a profession, which has not been introduced in all Western EU countries.

Dental public health is one of the nine specialties of dentistry recognized by the American Dental Association Commission on Dental Accreditation. Dental public health has been defined as the "science and art of preventing and controlling dental diseases and promoting dental health through organized community efforts. It is that form of dental practice which serves the community as a patient rather than as an individual. It is concerned with the dental health education of the public, with applied dental research, and with the administration of group dental care programs as well as the prevention and control of dental diseases on a community basis." This article will describe the many career and educational pathways dentists may follow to become irvolved in the practice of dental public health.

International dental standards are vital in maintaining the safety and quality of both the products and materials used by dental professionals and the many oral health products used by members of the general public, yet many dentists will be unaware of the role standards play in their daily practice. In this article, Derek W. Jones outlines the vital work of the International Standards Organization and highlights how standards pervade nearly every dental procedure.
The benefit for the child from the judicious use of diagnostic dental radiography is improved dental health. The risk to the child from dental diagnostic radiation exposure appears to be extremely low. Despite the low risk, the dentist must minimize the child's exposure to ionizing radiation by using sound clinical judgment to determine what radiographs are necessary and to provide children with optimal protection from ionizing radiation.

Although reports on dental erosion have always appeared in the dental literature, there is currently a growing interest among researchers and clinicians. Potential risk factors for dental erosion are changed lifestyle and eating patterns, with increased consumption of acidic foods and beverages. Various gastrointestinal and eating disorders expose the dentition to frequent contacts with very acidic gastric content, which may lead to erosion. Whether these factors indeed lead, on a population scale, to a higher prevalence and incidence of erosion is yet to be established. This article summarizes the different aspects of the prevalence, pathology, etiology, assessment, prevention and treatment of dental erosion, and concludes with recommendations for future research.

Among various dental materials and their successful applications, a dental implant is a good example of the integrated system of science and technology involved in multiple disciplines including surface chemistry and physics, biomechanics, from macro-scale to nano-scale manufacturing technologies and surface engineering. As many other dental materials and devices, there are crucial requirements taken upon on dental implants systems, since surface of dental implants is directly in contact with vital hard/soft tissue and is subjected to chemical as well as mechanical bio-environments. Such requirements should, at least, include biological compatibility, mechanical compatibility, and morphological compatibility to surrounding vital tissues. In this review, based on carefully selected about 500 published articles, these requirements plus MRI compatibility are firstly reviewed, followed by surface texturing methods in details. Normally dental implants are placed to lost tooth/teeth location(s) in adult patients whose skeleton and bony growth have already completed. However, there are some controversial issues for placing dental implants in growing patients. This point has been, in most of dental articles, overlooked. This review, therefore, throws a deliberate sight on this point. Concluding this review, we are proposing a novel implant system that integrates materials science and up-dated surface technology to improve dental implant systems exhibiting bio- and mechano-functionalities.

In 2005, Public Act No. 161 (PA 161) was passed in Michigan, allowing dental hygienists to practice in approved public dental prevention programs to provide services for underserved populations while utilizing a collaborative agreement with a supervising dentist. The aims of this study were to assess how well dental and dental hygiene students and faculty members and practicing dental hygienists have been educated about PA 161, what attitudes and knowledge about the act they have, and how interested they are in additional education about it. University of Michigan dental and dental hygiene students and faculty members, students in other Michigan dental hygiene programs, and dental hygienists in the state were surveyed. Respondents (response rate) were 160 dental students (50%), 63 dental hygiene students (82%), 30 dental faculty members (26%), and 12 dental hygiene faculty members (52%) at the University of Michigan; 143 dental hygiene students in other programs (20%); and 95 members of the Michigan Dental Hygienists' Association (10%). The results showed that the dental students were less educated about PA 161 than the dental hygiene students, and the dental faculty members were less informed than the dental hygiene faculty members and dental hygienists. Responding dental hygiene faculty members and dental hygienists had more positive attitudes about PA 161 than did the students and dental faculty members. Most of the dental hygiene faculty members and dental hygienists knew a person providing services in a PA 161 program. Most dental hygiene students, faculty members, and dental hygienists wanted more education about PA 161. Overall, the better educated about the program the respondents were, the more positive their attitudes, and the more interested they were in learning more.

Dental surgeries refer to procedures that affect the dental tissues or their supporting structures. With the development of specific, efficacious, and conservative treatments, morbidity risks have been lowered and chances of benefiting the health of equids improved. Advances in quality of sedation, analgesia, and locoregional anesthesia allow a majority of dental surgeries to be performed in the standing patient. This update focuses on an orthograde endodontic technique, a minimally invasive buccotomy technique, with the potential to combine it with a transbuccal screw extraction technique, and revisits the AO pinless external fixator for fractures of the body of the mandible.

Periodontal disease and chronic gingivitis/stomatitis are the most common feline dental diseases. With routine dental care and increased emphasis on home oral hygiene, these diseases can be controlled. Cats can be seen with a number of other dental disorders, and improved treatment methods such as restorations of early subgingival resorptive lesions, endodontic therapy, and orthodontic therapy can be performed successfully. More study and research are necessary about the gingivitis/stomatitis syndrome and subgingival resorptive lesions so that improved prevention and treatment recommendations can be made.

The fact that a significant percentage of dentists employ dental hygienists raises an important question: Are dental practices that utilize a dental hygienist structurally and operationally different from practices that do not? This article explores differences among dental practices that operate with and without dental hygienists. Using data from the American Dental Association's 2003 Survey of Dental Practice, a random sample survey of U.S. dentists, descriptive statistics were used to compare selected characteristics of solo general practitioners with and without dental hygienists. Multivariate regression analysis was used to estimate the effect of dental hygienists on the gross billings and net incomes of solo general practitioners. Differences in practice characteristics--such as hours spent in the practice and hours spent treating patients, wait time for a recall visit, number of operatories, square feet of office space, net income, and gross billings--were found between solo general practitioners who had dental hygienists and those who did not. Solo general practitioners with dental hygienists had higher gross billings. Higher gross billings would be expected, as would higher expenses. However, net incomes of those with dental hygienists were also higher. In contrast, the mean waiting time for a recall visit was higher among dentists who employed dental hygienists. Depending on personal preferences, availability of qualified personnel, etc., dentists who do not employ dental hygienists but have been contemplating that path may want to further research the benefits and opportunities that may be realized.

The objectives of the equine dental physical examination are to detect and quantify oral and dental disorders, to propose and carry out their treatment, and to implement management programs. The veterinarian should be able to offer a prognosis and to detail any future treatment or management plans that may be required. These objectives should take into account the cost of these procedures, and the veterinarian should be prepared to offer a cost-benefit analysis of the problem and the proposed cures.

Objective: This study was conducted to assess the dental arch asymmetry in a Yemeni sample aged (18-25) years. Materials and Methods: The investigation involved clinical examination of 1479 adults; only 253 (129 females, 124 males) out of the total sample were selected to fulfill the criteria for the study sample. Study models were constructed and evaluated to measure mandibular arch dimensions. Three linear distances were utilized on each side on the dental arch: Incisal-canine distance, canine-molar distance and incisal-molar distance, which represent the dental arch segmental measurements. Results: When applying “t-test” at P < 0.05, no significant differences were found between the right and left canine-molar, incisal-canine and incisal-molar distances in both dental arches for both sexes. The greater variation (0.30 mm) was observed between right and left canine-molar distance in the maxillary dental arch in male and the smaller (0.04 mm) in the mandibular dental arch between the right and left canine-molar distance in females. Conclusion: The findings of the present study revealed a symmetrical pattern of dental arches, since the right and left sides showed no statistically significant difference. In general, it can be observed that the measurements related to the central incisors and canines have the widest range of reading and give the impression that the location of central incisor and canines to each other and to other teeth is the strongest factor in determining the dental arch asymmetry.

Dental erosion is a multifactorial condition. The consideration of chemical, biological and behavioral factors is fundamental for its prevention and therapy. Among the biological factors, saliva is one of the most important parameters in the protection against erosive wear. Objective This review discusses the role of salivary factors on the development of dental erosion. Material and Methods A search was undertaken on MEDLINE website for papers from 1969 to 2010. The keywords used in the research were "saliva", "acquired pellicle", "salivary flow", "salivary buffering capacity" and "dental erosion". Inclusion of studies, data extraction and quality assessment were undertaken independently and in duplicate by two members of the review team. Disagreements were solved by discussion and consensus or by a third party. Results Several characteristics and properties of saliva play an important role in dental erosion. Salivary clearance gradually eliminates the acids through swallowing and saliva presents buffering capacity causing neutralization and buffering of dietary acids. Salivary flow allows dilution of the acids. In addition, saliva is supersaturated with respect to tooth mineral, providing calcium, phosphate and fluoride necessary for remineralization after an erosive challenge. Furthermore, many proteins present in saliva and acquired pellicle play an important role in dental erosion. Conclusions Saliva is the most important biological factor affecting the progression of dental erosion. Knowledge of its components and properties involved in this protective role can drive the development of preventive measures targeting to enhance its known beneficial effects. PMID:23138733

Objectives: To investigate the potential influence of standard dental materials on dental MRI (dMRI) by estimating the magnetic susceptibility with the help of the MRI-based geometric distortion method and to classify the materials from the standpoint of dMRI. Methods: A series of standard dental materials was studied on a 1.5 T MRI system using spin echo and gradient echo pulse sequences and their magnetic susceptibility was estimated using the geometric method. Measurements on samples of dental materials were supported by in vivo examples obtained in dedicated dMRI procedures. Results: The tested materials showed a range of distortion degrees. The following materials were classified as fully compatible materials that can be present even in the tooth of interest: the resin-based sealer AH Plus® (Dentsply, Maillefer, Germany), glass ionomer cement, gutta-percha, zirconium dioxide and composites from one of the tested manufacturers. Interestingly, composites provided by the other manufacturer caused relatively strong distortions and were therefore classified as compatible I, along with amalgam, gold alloy, gold–ceramic crowns, titanium alloy and NiTi orthodontic wires. Materials, the magnetic susceptibility of which differed from that of water by more than 200 ppm, were classified as non-compatible materials that should not be present in the patient’s mouth for any dMRI applications. They included stainless steel orthodontic appliances and CoCr. Conclusions: A classification of the materials that complies with the standard grouping of materials according to their magnetic susceptibility was proposed and adopted for the purposes of dMRI. The proposed classification can serve as a guideline in future dMRI research. PMID:23610088

Dental hygiene is defined as the science and practice of the recognition, treatment and prevention of oral diseases. The history of dental hygiene research is considered in the context of the development of the discipline and an emerging infrastructure. Research-related events supporting the growth and maturation of the profession are considered from the early years to the most recent. The benefits of preventive oral health services provided by dental hygienists have been supported by research, and the practice of dental hygiene has expanded as a result of research findings since its inception 100 years ago. Dental hygienists' engagement in research, however, did not begin until the 1960s as research associates or administrators, primarily with dental researchers as primary investigators. The Journal of Dental Hygiene (JDH) has provided information for dental hygiene practice since 1927, and has been the primary venue for dissemination of dental hygiene research since 1945. Graduate education in dental hygiene at the master's degree level and the work of early dental hygiene researchers led to the first conference on dental hygiene research in 1982. Over 30 years later, dental hygiene has established a meta-paradigm and defined conceptual models, built an initial infrastructure to support research endeavors and contributed much to the development of dental hygiene as a unique discipline. A doctoral degree in the discipline, continued theory-based research, initiatives to foster collaborations between dental hygiene and other researchers and enhanced capabilities to attract funding to support large scale studies are goals that must be attained through the efforts of future researchers to address the needs for additional development in the discipline of dental hygiene. Dental hygiene research supports the growing discipline and its value to society.

Dental ethics is often taught, viewed, and conducted as an intell enterprise, uninformed by other noncognitive factors. Emotional intelligence (EQ) is defined distinguished from the cognitive intelligence measured by Intelligence Quotient (IQ). This essay recommends more inclusion of emotional, noncognitive input to the ethical decision process in dental education and dental practice.

In 1921, New Zealand began training school dental nurses, subsequently deploying them throughout the country in school-based clinics providing basic dental care for children. The concept of training dental nurses, later to be designated dental therapists, was adopted by other countries as a means of improving access to care, particularly for children. This paper profiles six countries that utilise dental therapists, with a description of the training that therapists receive in these countries, and the context in which they practice. Based on available demographic information, it also updates the number of dental therapists practising globally, as well as the countries in which they practice. In several countries, dental therapy is now being integrated with dental hygiene in training and practice to create a new type of professional complementary to a dentist. Increasingly, dental therapists are permitted to treat adults as well as children. The paper also describes the status of a current initiative to introduce dental therapy to the United States. It concludes by suggesting that dental therapists can become valued members of the dental team throughout the world, helping to improve access to care and reducing existing disparities in oral health.

Dental amalgam has served as an excellent and versatile restorative material for many years, despite periods of controversy. The authors review its history, summarize the evidence with regard to its performance and offer predictions for the future of this material. The PubMed database was used initially; the reference list for dental amalgam featured 8641 articles and 13 publications dealing with recent advances in dental amalgam. A forward search was undertaken on selected articles and using some author names. For the present, amalgam should remain the material of choice for economic direct restoration of posterior teeth. When esthetic concerns are paramount, tooth-colored materials, placed meticulously, can provide an acceptable alternative. All alternative restorative materials and procedures, however, have certain limitations. PMID:21217947

Inflammatory periodontal disease is a major cause of loss of tooth-supporting structures. Novel approaches for regeneration of periodontal apparatus is an area of intensive research. Periodontal tissue engineering implies the use of appropriate regenerative cells, delivered through a suitable scaffold, and guided through signaling molecules. Dental pulp stem cells have been used in an increasing number of studies in dental tissue engineering. Those cells show mesenchymal (stromal) stem cell-like properties including self-renewal and multilineage differentiation potentials, aside from their relative accessibility and pleasant handling properties. The purpose of this article is to review the biological principles of periodontal tissue engineering, along with the challenges facing the development of a consistent and clinically relevant tissue regeneration platform. This article includes an updated review on dental pulp stem cells and their applications in periodontal regeneration, in combination with different scaffolds and growth factors. PMID:26620980

The clinical success of modern dental ceramics depends on an array of factors, ranging from initial physical properties of the material itself, to the fabrication and clinical procedures that inevitably damage these brittle materials, and the oral environment. Understanding the influence of these factors on clinical performance has engaged the dental, ceramics, and engineering communities alike. The objective of this review is to first summarize clinical, experimental, and analytic results reported in the recent literature. Additionally, it seeks to address how this new information adds insight into predictive test procedures and reveals challenges for future improvements. PMID:21224408

Epilepsy is a neurological condition characterised by seizure activity. It has an approximate incidence of 1%. General dental practitioners will encounter these patients in practice. This article discusses the types of epilepsy, the medical management and considerations in dental management of epileptic patients. General recommendations are made, based on current evidence, with respect to prescribing of medications. The management of an epileptic seizure is discussed. Status epilepticus is a rare but serious complication of epileptic seizures. An easy-to-follow algorithm is provided to assist the practitioner in managing seizures.
All exploration class missions--extending beyond earth's orbit--differ from existing orbital missions by being of longer duration and often not having a means of evacuation. If an exploration mission extends beyond a year, then there will be a greater lapse since the crewmembers last terrestrial dental exams, which routinely occur each year. This increased time since professional dental care could increase the chance of a dental emergency such as intractable pain, dental decay requiring a temporary filling, crown replacement, exposed pulp, abscess, tooth avulsion, or toothache. Additionally, any dental emergency will have to be treated in-flight with available resources and personnel who may not have extensive training in dental care. Thus, dental emergencies are an important risk to assess in preparation for exploration missions.
Dental caries result from erosion of tooth enamel or cementum by acidic substances produced by bacteria found in dental plaque. Caries can lead to pulp necrosis and tooth loss. Risk factors include certain dietary habits, poor oral hygiene, and dry mouth. Diabetes and Sjogren's syndrome can also promote dental caries. Psychotropic substances such as cocaine, methamphetamine, heroin and cannabis can promote dental caries. Many medicinal drugs facilitate the formation of dental caries, through various mechanisms; they include formulations with a high sugar content; drugs that cause dry mouth (especially antimuscarinics); drugs that lower the buccal pH (inhaled powders, etc.); and drugs that cause demineralisation (tetracyclines, etc.). In practice, patients (and parents) should be informed that some drugs can increase the risk of dental caries. They should be encouraged to adapt and reinforce dental hygiene, and advised to visit a dentist regularly.

Smoking is a prevalent behaviour in the population. The aim of this review is to bring to light the effects of smoking on dental implants. These facts will assist dental professionals when implants are planned in tobacco users. A search of “PubMed” was made with the key words “dental implant,” “nicotine,” “smoking,” “tobacco,” and “osseointegration.” Also, publications on tobacco control by the Government of India were considered. For review, only those articles published from 1988 onward in English language were selected. Smoking has its influence on general as well as oral health of an individual. Tobacco negatively affects the outcome of almost all therapeutic procedures performed in the oral cavity. The failure rate of implant osseointegration is considerably higher among smokers, and maintenance of oral hygiene around the implants and the risk of peri-implantitis are adversely affected by smoking. To increase implant survival in smokers, various protocols have been recommended. Although osseointegrated dental implants have become the state of the art for tooth replacement, they are not without limitations or complications. In this litigious era, it is extremely important that the practitioner clearly understands and is able and willing to convey the spectrum of possible complications and their frequency to the patients.

Objectives Clinical data on survival rates reveal that all-ceramic dental prostheses are susceptible to fracture from repetitive occlusal loading. The objective of this review is to examine the underlying mechanisms of fatigue in current and future dental ceramics. Data/sources The nature of various fatigue modes is elucidated using fracture test data on ceramic layer specimens from the dental and biomechanics literature. Conclusions Failure modes can change over a lifetime, depending on restoration geometry, loading conditions and material properties. Modes that operate in single-cycle loading may be dominated by alternative modes in multi-cycle loading. While post-mortem examination of failed prostheses can determine the sources of certain fractures, the evolution of these fractures en route to failure remains poorly understood. Whereas it is commonly held that loss of load-bearing capacity of dental ceramics in repetitive loading is attributable to chemically-assisted 'slow crack growth' in the presence of water, we demonstrate the existence of more deleterious fatigue mechanisms, mechanical rather than chemical in nature. Neglecting to account for mechanical fatigue can lead to gross overestimates in predicted survival rates. Clinical significance Strategies for prolonging the clinical lifetimes of ceramic restorations are proposed based on a crack-containment philosophy. PMID:24135295

Dental anxiety is still prevalent, despite advances in treatment, and affects the utilization of health care services. The purpose of this cross-sectional study was to determine if patients with different degrees of dental anxiety and pain undergoing emergency dental care have different stress reactions as measured by salivary cortisol. Seventy three patients completed the modified dental anxiety scale (MDAS), and described any previous dental traumatic experience. Their socio-demographic characteristics were also recorded. They also rated pain intensity on a 100 mm visual analogue scale (VAS). A saliva sample was collected before the procedure, and analyzed by enzyme immunoassay. Thirty patients were dentally anxious and forty one complained of pain. In this sample, dental anxiety was not related to gender, age, educational level and family income; however, a previous traumatic event was related to dental anxiety. There was no association between salivary cortisol concentrations and gender or dental anxiety. Patients with pain showed higher cortisol levels. When gathering patient information, the dentist should note patients' negative dental experiences in order to provide more effective, less traumatic treatment.

In Germany, the dental curriculum is still based on dental licensing regulations ("Approbations-/Prüfungsordnung für Zahnärzte") from 1955. Essential changes of the dental licensing regulations have not been made for over 50 years-unlike the medical licensing regulations in Germany. Teaching and learning concepts have, nevertheless, changed considerably in medical and dental education over time. The present study delivers an analysis about reform initiatives in dental education in Germany and introduces examples of innovative projects. To be able to establish long-term and broad reforms in dental education, new licensing regulations for dentists are required. This should create a contemporary framework for education, which assigns resources and enables occupational profile development at specific locations. Thereby, compatibility with the medical curriculum has to be guaranteed just as required adaptations of admission and curricular capacity regulations for dentistry.

Dental access disparities are well documented and have been recognized as a national problem. Their major cause is the lack of reasonable Medicaid reimbursement rates for the underserved. Specifically, Medicaid reimbursement rates for children average 40 percent below market rates. In addition, most state Medicaid programs do not cover adults. To address these issues, advocates of better oral health for the underserved are considering support for a new allied provider--a dental therapist--capable of providing services at a lower cost per service and in low-income and rural areas. Using a standard economic analysis, this study estimated the potential cost, price, utilization, and dentist's income effects of dental therapists employed in general dental practices. The analysis is based on national general dental practice data and the broadest scope of responsibility for dental therapists that their advocates have advanced, including the ability to provide restorations and extractions to adults and children, training for three years, and minimum supervision. Assuming dental therapists provide restorative, extraction, and pulpal services to patients of all ages and dental hygienists continue to deliver all hygiene services, the mean reduction in a general practice costs ranges between 1.57 and 2.36 percent. For dental therapists treating children only, the range is 0.31 to 0.47 percent. The effects on price and utilization are even smaller. In addition, the effects on most dentists' gross income, hours of work, and net income are negative. The estimated economic impact of dental therapists in the United States on private dental practice is very limited; therefore, the demand for dental therapists by private practices also would probably be very limited.

Odontophobia is a rather unique phobia with special psychosomatic components that impact on the dental health of odontophobic persons. It also has psychosocial components largely as a result of destruction of the teeth and subsequent embarrassment that can affect a person and cause a vicious cycle of dental fear. The phenomenon is facilitated by misunderstandings and myths generated by both patients and dentists. The most common reasons given in the literature for such strong fears of dental treatment are: 1) bad experiences in childhood for 85% of cases, 2) feeling of powerlessness and lack of control over personal emotional reactions and over the social situation in the dental chair, 3) social learning processes in which the image of the dentist is cast in a negative light by the mass media or by the person's relatives or friends and 4) that the person has other psychologic problems (in 20% of cases), such as serious phobias and/or neuroses. A strategy of researching and thus tackling the problem is presented which focuses on three essential targets that require studying and change: 1) the community at large and their image of the dentist, 2) the patient role and 3) the dentist role. Various model projects are presented along with their diagnostic systems. These are seen to focus in varying degrees on different elements of the target groups that effect the dentist-patient relationship but the need to come out into the community and make the social environment right for these patients is an important factor in all strategies.(ABSTRACT TRUNCATED AT 250 WORDS)

The escalating number and size of dental practices mean greater dependency on a ready supply of allied dental personnel. However, despite the increasing number of entry places in allied dental training programs, many places remain unfilled and large numbers of individuals do not complete the course of studies. A review of the changes in dental practice sizes and dental assistant, dental hygienist and dental laboratory technician programs raises concerns as to whether there will be enough allied dental personnel to meet the future needs of the profession. The need for increasing attention to this potential eventuality is stressed.

Anxiety is a significant issue in the dental care of adults and children. Dental anxiety often leads to avoidance of dental care which may result in significant deterioration of oral and dental health. Non-pharmacological anxiety management interventions such as music listening are increasingly used in dental care. Although efficacy for music's anxiolytic effects has been established for pre-operative anxiety, findings regarding the use of music listening for dental anxiety are inconclusive, especially for children. The use of music for passive distraction may not be adequate for children and highly anxious adults. Instead, interventions offered by a trained music therapist may be needed to optimize music's anxiolytic impact. Music therapy interventions are individualized to the patient's presenting needs and geared at enhancing patients' active engagement in the management of their anxiety. Interventions may include (i) active refocusing of attention, (ii) music-guided deep breathing, (iii) music-assisted relaxation, and (iv) music-guided imagery. In addition, music therapists can teach patients music-based anxiety management skills prior to dental treatments, offer them the opportunity to express emotions related to the upcoming procedure, and help them gain a sense of control and safety. Clinical guidelines for the use of music listening by dental practitioners are offered.

With the advent of nanotechnology, an opportunity exists for the engineering of new dental implant materials. Metallic dental implants have been successfully used for decades, but they have shortcomings related to osseointegration and mechanical properties that do not match those of bone. Absent the development of an entirely new class of materials, faster osseointegration of currently available dental implants can be accomplished by various surface modifications. To date, there is no consensus regarding the preferred method(s) of implant surface modification, and further development will be required before the ideal implant surface can be created, let alone become available for clinical use. Current approaches can generally be categorized into three areas: ceramic coatings, surface functionalization, and patterning on the micro- to nanoscale. The distinctions among these are imprecise, as some or all of these approaches can be combined to improve in vivo implant performance. These surface improvements have resulted in durable implants with a high percentage of success and long-term function. Nanotechnology has provided another set of opportunities for the manipulation of implant surfaces in its capacity to mimic the surface topography formed by extracellular matrix components of natural tissue. The possibilities introduced by nanotechnology now permit the tailoring of implant chemistry and structure with an unprecedented degree of control. For the first time, tools are available that can be used to manipulate the physicochemical environment and monitor key cellular events at the molecular level. These new tools and capabilities will result in faster bone formation, reduced healing time, and rapid recovery to function.

Tooth loss is very a very common problem; therefore, the use of dental implants is also a common practice. Although research on dental implant designs, materials and techniques has increased in the past few years and is expected to expand in the future, there is still a lot of work involved in the use of better biomaterials, implant design, surface modification and functionalization of surfaces to improve the long-term outcomes of the treatment. This paper provides a brief history and evolution of dental implants. It also describes the types of implants that have been developed, and the parameters that are presently used in the design of dental implants.

Dental science researchers do not really need a detailed, ready-at-hand knowledge of statistics to design and perform high quality scientific research. Although the acquisition and utilization of such knowledge by dental researchers is not discouraged, it is proposed that it is more important for dental researchers to be committed to developing and maintaining a long term, ongoing, interactive consulting relationship with a biostatistician. The nature of this relationship will depend in large part on the complexity of the dental research being conducted. While the statistical consultant will assist in interpreting analytic results for the dental researcher, the latter will need to provide extensive input in assisting in the estimation of sample size and power, and for expressing scientific hypotheses in statistical terms so that the appropriate data analytic methodology can be specified.
The American Dental Dream-the cultural desire for straight, white teeth-is difficult, if not impossible, for poor and working-class people to achieve. Using ethnographic fiction, autoethnography, poetry, and qualitative interviewing, I brush away the taken-for-granted assumptions about teeth. I explore the personal, relational, and structural consequences of this cultural desire, and show how social class writes itself on our bodies. I write these culture-centered teeth tales to show how one might cope with their teeth.

We have investigated the potential of lasers for real time in situ dental diagnosis via transillumination of teeth and gums and via fluorescence. Not surprisingly, absorption and/or scattering of light by teeth was found to be insensitive to light color. However, monochromatic transillumination revealed detail better than white light. Transillumination of gums was best performed with orange-red light because of tissue absorption. Illumination of oral structures by 488 nm Ar-laser light was effective in revealing diagnosis detail by fluorescence. Incipient caries and fine tooth fracture lines that are generally not revealed by radiography were observable by laser.
It is clear that many impression materials are available to the veterinary dentist. They each have different inherent properties, handling characteristics, and indications for use. A thorough understanding of these concepts is essential if the veterinarian and laboratory technician are to produce meaningful and accurate reproductions of oral structures. New products are constantly being introduced to the dental market, with fantastic claims for ease of use and reproduction of detail. The reader is urged to seek independent research findings when assessing such claims, and make decisions founded in the highest possible levels of evidence.

The changing role of dental hygienists deserves dental and dental hygiene educators' attention. The first aim of this survey study was to assess University of Michigan dental, dental hygiene, and graduate students' and faculty members' perceptions of dental hygienists' roles; their attitudes and behaviors related to clinical interactions between dental and dental hygiene students; and perceived benefits of engaging dental hygiene students as peer teachers for dental students. The second aim was to assess whether one group of dental students' experiences with dental hygiene student peer teaching affected their perceptions of the dental hygiene profession. Survey respondents were 57 dental hygiene students in all three years of the program (response rate 60% to 100%); 476 dental students in all four years (response rate 56% to 100%); 28 dental and dental hygiene graduate students (response rate 28%); and 67 dental and dental hygiene faculty members (response rate 56%). Compared to the other groups, dental students reported the lowest average number of services dental hygienists can provide (p≤0.001) and the lowest average number of patient groups for which dental hygienists can provide periodontal care (p<0.001). Dental students also had the least positive attitudes about clinical interactions between dental hygiene and dental students (p<0.001) and perceived the fewest benefits of dental hygiene student peer teaching (p<0.001) before experiencing peer teaching. After experiencing dental hygiene student peer teaching, the dental students' perceptions of dental hygienists' roles, attitudes about clinical interactions with dental hygienists, and perceived benefits of dental hygiene student peer teachers improved and were more positive than the responses of their peers with no peer teaching experiences. These results suggest that dental hygiene student peer teaching may improve dental students' perceptions of dental hygienists' roles and attitudes about

Dental schools in Japan are among many worldwide whose medium of instruction is not in English. With advances in science, technology, and communication, the demand for the globalization of professions increases. At present, dental schools in Asia, the Middle East, and Europe have started revising their dental curricula to either include English courses for dentistry or offer a full English dental curriculum. In Japan, dental English courses started to be introduced into curricula in the early 1990s. However, a survey conducted in 1999 found that English courses were not offered in Japan's twenty-nine dental schools and there was no consensus as to what such courses should include or when and how they should be taught. Ten years after that survey, the survey results reported in this article found that the problems reported in the 1999 survey still exist. Additionally, there are still differences among schools offering English courses in terms of the timing and contents of the courses. Since teachers and school officials will have an important role in curriculum development, this article recommends that a fact-finding meeting with educators, school, and education officials be initiated to discuss, develop, and implement a core curriculum for these dental English courses.

The aim of the present study was to investigate dental coping strategies, general anxiety, and depression in relation to regularity of dental treatment among persons with either regular dental care or phobic avoidance, whilst controlling for sociodemographic factors. Psychometric questionnaires on dental anxiety, dental coping strategies, general anxiety, and depression were delivered to 263 adult patients with dental phobic avoidance behavior who were seeking help from a specialized dental fear clinic and to 141 adult patients with dental anxiety who were receiving regular dental care from various public dental clinics. The results showed that the levels of dental and general anxiety and of depression were significantly higher among irregular attendees compared with regular attendees. Irregular attendees admitted fewer adaptive coping strategies. Predictive of irregular dental care were gender, dental anxiety, general anxiety, and the nonuse of the coping strategy 'optimism'. This study further confirms earlier preliminary results that the use of optimistic thinking is predictive for regular dental attendance habits and that male gender is a risk factor for irregular attendance. Moreover, this study adds that a high level of general anxiety indicates a higher risk for irregular dental care.

Dental implants have been considered an acceptable form of dental treatment since the early 1980s. A number of studies have been published describing impression techniques for dental implants. Many of the techniques described are so complex that they may seem daunting to the average restorative dentist. Most general practitioners do not wish to attempt to restore dental implants. This article describes a very simple, yet extremely accurate, technique for making impressions of dental implant fixtures.

The dental health data for the Iowa Department of Corrections (IDOC) inmate population were analyzed to better understand dental health issues experienced by inmates and IDOC's system for responding to those dental needs. Each inmate is given a dental health assessment upon admission to Iowa's prison system. These data were analyzed for frequency of dental health needs and frequency of dental health services. In addition, emergency dental health services were analyzed. The findings show that each inmate has approximately 7.6 dental codes, including the initial exam, dental services provided, and dental needs not yet addressed. When reviewing only dental needs (and not the initial exam), 32% (5,110) identified dental needs were completed and 66% (10,572) were not.

This paper presents a roughness measurement of zirconia ceramics, widely used for dental applications. Surface roughness variations caused by the most commonly used dental instruments for intraoral grinding and polishing are estimated. The applied technique is simple and utilizes the speckle properties of the scattered laser light. It could be easily implemented even in dental clinic environment. The main criteria for roughness estimation is the average speckle size, which varies with the roughness of zirconia. The algorithm used for the speckle size estimation is based on the normalized autocorrelation approach.
Allergic reactions to dental materials and remedies cause stomatitis in the patient and a contact dermatitis in the dental personnel. Topical contact (acrylic resin denture materials, heat accumulation, plaques on the denture) and endogenic (symptom of internal and psychiatric illnesses) factors are the cause for denture sore mouth. In metallic alloys corrosions and electric currents can effect an irritation to the oral mucosa. The application of amalgam fillings can possibly result in a mercurialism. Dental remedies used for treatment of wounds and dental roots are potent sensitizers. Surface anesthetics with tetracaine are the most frequent contact allergens for dentists. Injectable local anesthetics produce anaphylactic type reactions as well as toxic side-effects in the patient.

In a questionnaire survey, dental students from all four classes at The University of Iowa College of Dentistry were asked if they had cheated during their first and second years. They were then asked if they believed that others cheated. Cheating was admitted to by 43 percent of the respondents, but 94 percent believed it was occurring. Plagiarism was delineated as a form of cheating; while fewer students admitted to its use, the reported occurrence should be of concern in technique courses. Responses were analyzed both by year in school and grade point average. Reasons for cheating were described; and some conditions conducive to cheating were found to be under the control of the instructor.
Straightening teeth is an arduous process requiring months, often years, of applying corrective pressure by means of arch wires-better known as brace-which may have to be changed several times in the course of treatment. A new method has been developed by Dr. George Andreasen, orthodontist and dental scientist at the University of Iowa. The key is a new type of arch wire material, called Nitinol, with exceptional elasticity which helps reduce the required number of brace changes. An alloy of nickel and titanium, Nitinol was originally developed for aerospace applications by the Naval Ordnance Laboratory, now the Naval Surface Weapons Laboratory, White Oaks, Maryland. NASA subsequently conducted additional research on the properties of Nitinol and on procedures for processing the metal.

The most recent epidemiological data on the prevalence of dental caries in children indicate a halting of the increasing levels in many developing countries and a continuing decrease in many highly industrialized countries of the world. However, a further fall in caries levels predicted for 5-yr-old children in the U.K. has not occurred and the decline in caries may have begun to level out. 'Polarization' of caries to a minority of high-risk individuals is occurring in the developed world, with 20-25% of children accounting for more than 50% of the disease. Socio-economic factors are important in determining the proportion of high-risk children in these countries. The multifactorial aetiology of caries allows a number of different interpretations to account for changes in the prevalence of the disease with time, in both the developing and developed countries. These changes are variously ascribed to alterations in dietary habits, especially the consumption of sugar; variations in the patterns of oral hygiene; increased contact with trace elements, especially fluoride, in the environment; changes in the ecology and/or virulence of oral and dental plaque microflora and alterations in the oral protective mechanisms including the immune status. The epidemiological evidence available on the relationship of all these social, environmental and other factors to changes in the prevalence levels of caries does not, however, fully explain all the changes that have been observed. The claim that caries is no longer a public health problem is premature, as it ignores the still high proportion of individuals with tooth decay throughout the world.

Dental insurance is insurance designed to pay the costs associated with dental care. The Foreign Direct Investment (FDI) bill which was put forward in the winter session of the Lok Sabha (2008) focused on increasing the foreign investment share from the existing 26% to 49% in the insurance companies of India. This will allow the multibillion dollar international insurance companies to enter the Indian market and subsequently cover all aspects of insurance in India. Dental insurance will be an integral a part of this system. Dental insurance is a new concept in Southeast Asia as very few countries in Southeast Asia cover this aspect of insurance. It is important that the dentists in India should be acquainted with the different types of plans these companies are going to offer and about a new relationship which is going to emerge in the coming years between dentist, patient and the insurance company.

Dental abscess is a frequently occurring infectious process known to the health practice. The fate of the infection depends on the virulence of the bacteria, host resistance factors, and regional anatomy. Serious consequences arising from the spread of a dental abscess lead to significant morbidity and mortality. Acute dental abscess is polymicrobial, comprising of strict anaerobes, such as anaerobic cocci, Prevotella, Fusobacterium species, and facultative anaerobes, such as viridans group streptococci and the Streptococcus anginosus group. Numerous novel, uncultivable and fastidious organisms have been identified as potential pathogens with the use of non-culture techniques. The majority of localized dental abscesses respond to surgical treatment while the use of antimicrobials is limited to severe spreading infections. There is a need for good-quality clinical trials of sufficient size to identify the ideal treatment. The microbiology of the acute dentoalveolar abscess and its treatment in the light of improved culture and diagnostic methods are reviewed. PMID:24348613

The dental management of geriatric horses can be a rewarding challenge to the practitioner. Owners become dissatisfied when their expectations are unrealistic. Consequently, communication between the owner and the practitioner is essential prior to the start of any dental procedure in a geriatric horse. Owners often expect the practitioner to correct what has been neglected for years. It is critical that the owner understand the possible complications associated with dental procedures and that some procedures (e.g., trephination) may necessitate protracted care. Often, when a tooth has been removed, there is a need for more frequent masticatory examinations to curtail any potential problems (i.e., development of step mouth). The owner needs to be aware of the extra dental maintenance costs that must be included in the upkeep of the horse.

The focus for the achievement of complete success in the esthetic zone has traditionally been on addressing deficiencies of intraoral hard and soft tissue. Often, these deficiencies are accompanied by esthetic concerns regarding the lips that are routinely neglected by the dental team. A predictable plastic surgery technique - the lip lift - has been used for decades to enhance lip esthetics by shortening the senile upper lip to achieve a more youthful appearance. Over the years, this technique has been refined and used in many different ways, allowing its routine incorporation into full facial esthetic planning. Through restoration of the upper lip to its optimal position, the artistry of the dentist and dental technician can truly be appreciated in the rejuvenated smile. By the introduction of this minimally invasive surgical technique to the dental community, patients stand to benefit from a comprehensive orofacial approach to anterior dental esthetic planning.

Today's trend toward ambulatory medical care will bring more pharmacological problems into the dental office. While the dental management of patients taking oral anticoagulants is controversial, current research supports the contention that they can be safely treated on an outpatient basis. The use of the International Normalized Ratio (INR) has made better estimates of prothrombin time possible, and patients can be maintained in a narrow therapeutic range. Postoperative hemorrhage can be avoided or controlled with local hemostatic agents.

The application of surface topography measurement and characterization within dental materials science is highly active and rapidly developing, in line with many modern industries. Surface measurement and structuring is used extensively within oral and dental science to optimize the optical, tribological and biological performance of natural and biomimetic dental materials. Although there has historically been little standardization in the use and reporting of surface metrology instrumentation and software, the dental industry is beginning to adopt modern areal measurement and characterization techniques, especially as the dental industry is increasingly adopting digital impressioning techniques in order to leverage CAD/CAM technologies for the design and construction of dental restorations. As dental treatment becomes increasingly digitized and reliant on advanced technologies such as dental implants, wider adoption of standardized surface topography and characterization techniques will become evermore essential. The dental research community welcomes the advances that are being made in surface topography measurement science towards realizing this ultimate goal.

Early childhood dental caries occurs in all racial and socioeconomic groups; however, it tends to be more prevalent in children in families belonging to the low-income group, where it is seen in epidemic proportions. Dental caries results from an overgrowth of specific organisms that are a part of normally occurring human flora. Human dental flora is site specific, and an infant is not colonized until the eruption of the primary dentition at approximately 6 to 30 months of age. The most likely source of inoculation of an infant's dental flora is the mother, or another intimate care provider, shared utensils, etc. Decreasing the level of cariogenic organisms in the mother's dental flora at the time of colonization can significantly impact the child's redisposition to caries. To prevent caries in children, high-risk individuals must be identified at an early age (preferably high-risk mothers during prenatal care), and aggressive strategies should be adopted, including anticipatory guidance, behavior modifications (oral hygiene and feeding practices), and establishment of a dental home by 1 year of age for children deemed at risk.

Abstract Ensuring access to dental care, particularly for children, is a significant policy concern in the United States. Many factors affect access on both the provider and patient sides. This study examines an important factor in the ability to access dental care: the distribution and availability of dental health providers. The authors assess providers across the counties of Pennsylvania, primarily using data from the 2013 Survey of Dentists and Dental Hygienists administered by the Pennsylvania Department of Health. To identify possible dental provider shortages in Pennsylvania counties, the authors assessed ten indicators of access to dental providers. They find significant variation in the indicators across Pennsylvania counties. PMID:28083429

Over the last 5 to 7 years, dental teams have mastered the art and science of processing dental insurance for their patients but have major difficulties learning how to help their patients when it comes to medical insurance. This article attempts to provide a basic guide for the dental team in coding, billing, and processing of major medical insurance for dental sleep medicine. Although there is certainly a learning curve for the dental team in this endeavor, the "patient and physician friendly" dental sleep medicine practice is a model that will help to assure growth and success.

The objective of this study is to share cost analysis methodology and to obtain cost estimates for posterior restorations in public sector dental clinics. Two urban and 2 rural dental clinics in Selangor state were selected. Only cases of 1 posterior restoration per visit by dental officers were included over 6 months. One capsulated amalgam type, 1 capsulated tooth-colored, and 1 non-capsulated tooth-colored material were selected. A clinical pathway form was formulated to collect data per patient. Annual capital and recurrent expenditures were collected per clinic. The mean cost of an amalgam restoration was RM 30.96 (sdRM 7.86); and tooth-colored restorations ranged from RM 33.00 (sdRM 8.43) to RM 41.10 (sdRM 10.61). Wherein 1 USD = RM 2.8. Restoration costs were 35% to 55% higher in clinics in rural areas than in urban areas. The findings demonstrate economy of scale for clinic operation and restoration costs with higher patient load. Costs per restoration were higher in rural than in urban dental clinics. More studies are recommended to address the dearth of dental costs data in Malaysia.

The fluorescence of porcelain crowns recovered from the mouth of an unknown murder victim, and several control porcelain samples, were examined by fluorescent examination lamps. The fluorescence from two of the control samples was quite similar to that from the porcelain crowns recovered from the victim. To increase the objectivity of the results by quantitative analysis, the composition of each porcelain crown and control sample was also evaluated by wave dispersion X-ray microanalyser. The elements detected from the porcelain crowns of the victim matched those of two of the porcelain samples. Later, the antemortem dental records and radiographs of the victim were obtained through a dentist, who had recognized the name of the porcelain manufacturer in a postmortem dental information request placed on the Japanese Dental Association web page. Although component analysis of dental porcelain may be an effective means of assisting dental identification, a more rapid and non-destructive analysis for detecting the elements is required. The energy dispersive X-ray fluorescence (EDXRF) spectrometer was used for a pilot study of identification of porcelain composition.

Self-care behaviors are common and can act as substitutes for or supplements to formal health care services. We tested the hypothesis that problem-oriented dental attenders (POAs) report more dental self-care behaviors than do regular dental attenders (RAs), presumably as a substitute for professional care. The Florida Dental Care Study is a longitudinal cohort study of changes in oral health, in which we measured dental self-care behaviors related to three common dental problems: toothache pain, bleeding gums, and tooth loss. Despite using less dental care, POAs were less likely to report "conventional" methods as means to prevent the three dental problems; however, they were more likely to report that homemade remedies, topical medications, or mouthwashes were ways to prevent or treat these problems. POAs were also more likely to believe that "nothing can be done" to prevent these problems. Additionally, POAs had more negative dental attitudes, used less dental care during follow-up, had more dental disease, were the only persons who extracted at least one of their own teeth, and were more likely to use tobacco. With the exception of dental self-extractions, no single self-care belief or behavior distinguished POAs from RAs, nor were POAs likely to have different explanations for dental problems. Instead, the pattern was one of modest differences on a number of items. Although POAs use less dental care, they do not compensate by employing more "conventional" dental self-care behaviors, but report being more likely to employ "unconventional" behaviors. They also are more likely to believe that nothing can be done to prevent dental problems.

At a dental school in Canada, problem-based learning (PBL) sessions were restructured from an integrated dental-medical model to a separate dental model, resulting in three groups of students available for study: those who had participated in the two-year dental and medical combined, the one-year dental and medical combined, the one-year dental alone, and the two-year dental alone. The aim of this qualitative study was to examine the extent to which the PBL structure affected the dental students' perceptions of the learning value of PBL in the different models. A total of 34 first-, second-, and third-year dental students participated in six focus groups in May and June 2011 (34% of students in those total classes). Semistructured questions explored their experiences in the different PBL structures. The interviews were recorded and transcribed verbatim, and thematic analysis was employed. The results showed positive and negative perceptions for both the combined dental and medical settings and the settings with dental students alone. For students in the combined PBL groups, positive perceptions included gaining information from medical peers, motivation to learn, and interdisciplinary collaborations. The negative perceptions mainly related to irrelevant content, dominating medical students, and ineffective preceptors. Members of the separate dental groups were more positive about the content and felt a sense of belonging. They appreciated the dental preceptors but were concerned about the inadequacy of their medical knowledge. Overall, the dental students valued the combined PBL experience and appreciated the opportunity to learn with their medical colleagues. Close attention, however, must be paid to PBL content and the preceptor's role to optimize dental students' experience in combined medical and dental groups.

Dental plaque is being redefined as oral biofilm. Diverse overlapping microbial consortia are present on all oral tissues. Biofilms are structured, displaying features like channels and projections. Constituent species switch back and forth between sessile and planktonic phases. Saliva is the medium for planktonic suspension. Several major functions can be defined for saliva in relation to oral biofilm. It serves as a medium for transporting planktonic bacteria within and between mouths. Bacteria in transit may be vulnerable to negative selection. Salivary agglutinins may prevent reattachment to surfaces. Killing by antimicrobial proteins may lead to attachment of dead cells. Salivary proteins form conditioning films on all oral surfaces. This contributes to positive selection for microbial adherence. Saliva carries chemical messengers which allow live adherent cells to sense a critical density of conspecifics. Growth begins, and thick biofilms may become resistant to antimicrobial substances. Salivary macromolecules may be catabolized, but salivary flow also may clear dietary substrates. Salivary proteins act in ways that benefit both host and microbe. All have multiple functions, and many do the same job. They form heterotypic complexes, which may exist in large micelle-like structures. These issues make it useful to compare subjects whose saliva functions differently. We have developed a simultaneous assay for aggregation, killing, live adherence, and dead adherence of oral species. Screening of 149 subjects has defined high killing/low adherence, low killing/high adherence, high killing/high adherence, and low killing/low adherence groups. These will be evaluated for differences in their flora.

Medicaid was expanded to millions of individuals under the Affordable Care Act, but many states do not provide dental coverage for adults under their Medicaid programs. In the absence of dental coverage, patients may resort to costly emergency department (ED) visits for dental conditions. Medicaid coverage of dental benefits could help ease the burden on the ED, but ED use for dental conditions might remain a problem in areas with a scarcity of dentists. We examined county-level rates of ED visits for nontraumatic dental conditions in twenty-nine states in 2010 in relation to dental provider density and Medicaid coverage of nonemergency dental services. Higher density of dental providers was associated with lower rates of dental ED visits by patients with Medicaid in rural counties but not in urban counties, where most dental ED visits occurred. County-level Medicaid-funded dental ED visit rates were lower in states where Medicaid covered nonemergency dental services than in other states, although this difference was not significant after other factors were adjusted for. Providing dental coverage alone might not reduce Medicaid-funded dental ED visits if patients do not have access to dental providers.

ABSTRACT Objective To check knowledge of undergraduate dental students to make diagnosis of dental fluorosis with varying degrees of severity and choose its appropriate treatment. Methods Data were collected using a semi-structured questionnaire addressing knowledge of undergraduates based on ten images of mouths presenting enamel changes. Results Only three images were correctly diagnosed by most undergraduates; the major difficulty was in establishing dental fluorosis severity degree. Conclusion Despite much information about fluorosis conveyed during the Dentistry training, as defined in the course syllabus, a significant part of the students was not able to differentiate it from other lesions; they did not demonstrate expertise as to defining severity of fluorosis and indications for treatment, and could not make the correct diagnosis of enamel surface changes.

This article examines the financing of dental care in the United States. The major issues addressed include the amount and sources of funds, the reasons for increased dental care expenditures, the comparison of dental care with other medical care expenditures, the policy implications of current trends, and some cautious predictions about the financing of dental care in the next 10 to 20 years. The supply of dental services is expected to increase substantially in the next 10 to 20 years with more dental school graduates, a new midlevel practitioner, and greater use of allied dental health personnel. Whether the supply of services will grow faster than the demand for care is unknown.

Significant numbers of patients visiting the paediatric dental clinics have aesthetically objectionable brown stains and desire treatment for them. Intrinsic tooth discolouration can be a significant aesthetic, and in some instances, functional, problem. Dental fluorosis, tetracycline staining, localised and chronological hypoplasia, and both amelogenesis and dentinogenesis imperfecta can all produce a cosmetically unsatisfactory dentition. The aetiology of intrinsic discolouration of enamel may sometimes be deduced from the patient's history, and one factor long associated with the problem has been a high level of fluoride intake. Optimal use of topical fluorides leads to a decrease in the caries prevalence but may show an increase in the prevalence of fluorosis staining because of metabolic alterations in the ameloblasts, causing a defective matrix formation and improper calcification. A 12-year-old male patient was screened at the dental clinic for routine dental care. He wanted us to remove and/or minimise the noticeable brown/yellow staining of his teeth. He requested the least invasive and most cost-effective treatment to change his smile. Various treatment modalities are present for the treatment of fluorosis stains. This report discusses the microabrasion technique in the patient having dental fluorosis.
Many different surgical procedures have over the years been attributed to the ancient Egyptians. This is also true regarding the field of dental surgery. The existence of dentists in ancient Egypt is documented and several recipes exist concerning dental conditions. However, no indications of dental surgery are found in the medical papyri or in the visual arts. Regarding the osteological material/mummies, the possible indications of dental surgery are few and weak. There is not a single example of a clear tooth extraction, nor of a filling or of an artificial tooth. The suggested examples of evacuation of apical abscesses can be more readily explained as outflow sinuses. Regarding the suggested bridges, these are constituted of one find likely dating to the Old Kingdom, and one possibly, but perhaps more likely, dating to the Ptolemaic era. Both seem to be too weak to have served any possible practical purpose in a living patient, and the most likely explanation would be to consider them as a restoration performed during the mummification process. Thus, while a form of dentistry did certainly exist in ancient Egypt, there is today no evidence of dental surgery.

Thalassemias constitute a form of anemia that pose clear problems in relation to dental treatment. Dental professionals must be aware of the treatment adaptations required in patients with severe forms of beta-thalassemia. Until medical research is able to afford a definitive solution to these diseases (thereby greatly simplifying the dental management of such patients), effort will continue to center on the improvement of available therapeutic modalities, with the aim of obtaining effective and inexpensive oral chelators and drugs that either individually or in combination allow increases in fetal hemoglobin levels. Undoubtedly, the use of such measures together with serial blood transfusions has made it possible for an ever increasing number of patients with beta-thalassemia to reach adult age, where the provision of integral rather than merely palliative dental treatment must be seriously considered. At present, the clinical orofacial manifestations caused by the erythroid mass expanding the facial bones - resulting in dental malocclusions and protrusions tend to be less intense as a result of early medical treatment. In the future, gene therapy may be expected to allow a normal facial appearance thanks to complete healing of the patient.

There is very little information about the practice of sedation in Japan. Despite the remarkable advances in dentistry, fear and anxiety continue to be significant deterrents for seeking dental services. Most dental procedures can fortunately be undertaken with the aid of sedation. A comprehensive survey of all the dental schools in Japan was carried out to determine what sedation practices were used in Japan. All 29 dental schools in Japan possessed a dedicated department of anesthesiology at the time of this survey. The survey attempted to determine the specific sedation methods (techniques, routes of administration, and agents used in sedation) as well as practices (monitoring, fasting, location, education, and fees involved in sedation). The results indicate that there was a broad range in sedation practices. The Japanese Dental Society of Anesthesiology may wish to examine the findings of this study and may wish to formulate guidelines appropriate for the practice of sedation in Japan. Others may also wish to compare their own practices with those of Japan. PMID:15497299

Although the reduction and prevalence of dental caries in many countries has been largely associated with the use of fluorine and improving dental hygiene, eating habits also play a role in the development of caries. Fermentable carbohydrates characteristics of the food, rate of consumption, food protectors, the quality and quantity of saliva indices that determine the remineralization of teeth are factors to be considered. All these elements are analyzed through the sociodemographic, behavioral, physical and biological environment directly or indirectly with diet and caries.

Dental wear is loss of tooth structure resulting from erosion, attrition, abrasion, and, possibly, abfraction. Clinical/experimental data suggest no single damaging mechanism but rather simultaneous interaction of these destructive processes. The most important interaction is abrasion/attrition potentiated by dental erosion. Awareness of this pathosis is not well-appreciated by the public and dental professionals because the signs may be subtle. This article focuses on the recognition, diagnosis, and management of dental wear.

Oral health has a significant impact on the quality of life, appearance, and self-esteem of the people. Preventive dental visits help in the early detection and treatment of oral diseases. Dental care utilization can be defined as the percentage of the population who access dental services over a specified period of time. There are reports that dental patients only visit the dentist when in pain and never bother to return for follow-up in most cases. To improve oral health outcomes an adequate knowledge of the way the individuals use health services and the factors predictive of this behavior is essential. The interest in developing models explaining the utilization of dental services has increased; issues like dental anxiety, price, income, the distance a person had to travel to get care, and preference for preservation of teeth are treated as barriers in regular dental care. Published materials which pertain to the use of dental services by Indian population have been reviewed and analyzed in depth in the present study. Dental surgeons and dental health workers have to play an adequate role in facilitating public enlightenment that people may appreciate the need for regular dental care and make adequate and proper use of the available dental care facilities.

Syncope or Fainting is, by far, the most common emergency situation in the dental practice. Syncope is defined as an abrupt, transient, short term loss of consciousness and postural tone, followed by spontaneous and complete recovery. The pathophysiology of syncope consists of a sudden cessation or decrease in cerebral perfusion. Differential diagnosis of these medical conditions is of paramount importance in uncovering unrecognized systemic diseases. The dental team plays an important role in the process of establishing the correct diagnosis by its ability to recognize and document all the clinical symptoms and signs evident at the time of fainting. The dental surgeon is expected to be familiar with the various etiologies of syncope and should be able to differentiate between them. This article provides the essentials of the diagnostic procedure and an approach to the evaluation of the unconscious patient.

The advancements in science and technology allowed saving the lives of children, who had no chance of survival before. Hence the problem of so called rare diseases, usually genetically determined. It is a new challenge for both the physicians and the health services. These children require a coordinated multi specialist oriented health care, which includes also dentists. This situation is reflected by the case of an 18 years old girl with Rett Syndrome, described by us. In this patient despite numerous visits to various dental practices, no decision of a radical surgical extraction of the tooth has been conducted. In our Department the extraction of teeth 22, 16 and 14 has been performed, as a part of 1 day surgery procedures, thus eliminating the dental infections and pain. Conclusion: Elaboration and introduction into praxis principles of dental care in children and young adults with rare diseases are needed.
Aquatic biofilms, which are well-organized communities of microorganisms, are widespread in nature. They constitute a major problem in many environmental, industrial and medical settings. The use of advanced techniques has revealed biofilm structure, formation and ecology. Special attention was given to the build-up of biofilm in dental unit waterlines (DUWLs), which are small-bore flexible plastic tubing to bring water to different handpieces. They are coated with well-established biofilms. Active biofilm is a source of microbial contamination of DUWLs water. The safety of dental treatment requires a good quality of the water used. The knowledge of nature, formation and the ways to eliminate the biofilm is the first step towards reducing health risk, both for patients and dental personnel. The article reviews these issues.

Promotion of sound dietary practices is an essential component of caries management, along with fluoride exposure and oral hygiene practices. Scientific discoveries have lead to better understanding of the caries process, the ever-expanding food supply, and the interaction between the two. Fermentable carbohydrates interact dynamically with oral bacteria and saliva, and these foods will continue to be a major part of a healthful diet. Dental health professionals can serve their patients and the public by providing comprehensive oral health care and by promoting lifestyle behaviors to improve oral and general health within the time constraints of their practice. Dietary advice given should not contradict general health principles when providing practical guidance to reduce caries risk. The following principles should guide messages: * Encourage balanced diets based on moderation and variety as depicted by the Food Guide Pyramid and the Dietary Guidelines for Americans to provide a sound approach. Avoid references to "bad" foods and focus on "good" diets that include a variety of foods. * Give examples of how combining and sequencing foods can enhance mastication, saliva production, and oral clearance at each eating occasion. Combining dairy foods with sugary foods, raw foods with cooked, and protein-rich foods with acidogenic foods are all good examples. Suggest that eating and drinking be followed by cariostatic foods such as xylitol chewing gum. * Drink water to satisfy thirst and hydration needs as often as possible. Restrict consumption of sweetened beverages to meal and snack times when they can be combined with other cariostatic foods. * When a patient reports excessive dietary intake of a fermentable carbohydrate to the point of displacing other important foods in the diet, identify alternatives that will help the patient maintain or achieve a healthy body weight, oral health status, and a nutrient-dense intake.

Autism Spectrum Disorder (ASD) occurs in approximately 1% of the Dutch population. Among the group of patients with this disorder, there is a substantial diversity regarding skills, intelligence and treatability. However, there are also common characteristics; people with ASD often have difficulty with social interaction, communication, and exhibit typical patterns of behaviour. Therefore, problems may arise in the various areas of development, such as language development and responding to sensory stimuli. Dental practitioners will also be confronted with individuals with ASD. Care can be significantly improved, considering that negative experiences and dental anxiety are widespread at this time.

ABSTRACT Special and medically compromised patients present a unique population that challenges the dentist’s skill and knowledge. Providing oral care to people with cerebral palsy (CP) requires adaptation of the skills we use everyday. In fact, most people with mild or moderate forms of CP can be treated successfully in the general practice setting. This article is to review various dental considerations and management of a CP patient. How to cite this article: Sehrawat N, Marwaha M, Bansal K, Chopra R. Cerebral Palsy: A Dental Update.

Studies of the prevalence of dental anxiety in general population samples have produced estimates which range from a low of 2.6% to a high of 20.4%. It is not clear whether these reflect real differences among populations or whether they are the result of the use of different measures and different cut-off points. We undertook a large scale mail survey of dental anxiety in a random sample of the adult population living in Metropolitan Toronto designed to assess the performance of and agreement between three measures. These were Corah's DAS, the single item used by Milgrom and colleagues in Seattle and the ten-point fear scale used by Gatchel. These measures and their published cut-off points produced prevalence estimates of 10.9%, 23.4% and 8.2% respectively. While there was a significant association between scores on pairs of measures the agreement between them was far from perfect. Kappa values ranged from 0.37 to 0.56, indicating only fair to moderate agreement beyond chance. There was evidence to indicate that the dentally anxious subjects identified by each measure differed according to certain behavioural and other characteristics. The results of the study suggest the need to revisit the issue of measurement in studies of dental anxiety.

Undergraduate dental education programs have grown tremendously in India over the last five to six decades, mainly in the private sector, putting significant pressure on resources including faculty. This has raised concerns about the quality of dental education in the country. This article examines the concept of quality as applicable to higher education. It provides a roadmap for application of quality concepts, including steps for improving the effectiveness of teaching and applying Total Quality Management to dental education. It also makes suggestions for college-level and structural-level changes to meet the requirement of improved quality, which includes the addition of dental education as a subject in postgraduate dental programs.

The search for more accessible mesenchymal stem cells than those found in bone marrow has propelled interest in dental tissues. Human dental stem/progenitor cells (collectively termed dental stem cells [DSCs]) that have been isolated and characterized include dental pulp stem cells, stem cells from exfoliated deciduous teeth, stem cells from apical papilla, periodontal ligament stem cells, and dental follicle progenitor cells. Common characteristics of these cell populations are the capacity for self-renewal and the ability to differentiate into multiple lineages. In vitro and animal studies have shown that DSCs can differentiate into osseous, odontogenic, adipose, endothelial, and neural-like tissues.

Ketoprofen is a nonsteroidal antiinflammatory drug, recently approved as an over-the-counter (OTC) analgesic at a 12.5 mg dosage strength. This is the first published study which explores the analgesic efficacy and safety of ketoprofen 12.5 mg in patients experiencing pain following the removal of impacted third molars. This study was single-dose, double-blind and randomized utilizing a 6-hour in-patient evaluation period. Patients ingested a single dose of ketoprofen 12.5 mg (n = 30), ketoprofen 37.5 mg (n = 32) or placebo (n = 15) when their post-surgical pain reached at least a moderate intensity on a 5-point categorical (CAT) scale and greater than 50 mm on a 100 mm visual analog scale (VAS). Measures of pain intensity and relief were gathered every 20 minutes for the first 2 hours, and then hourly from hours 3 through 6. Adverse drug reactions were also recorded as they occurred. Both dosages of ketoprofen were significantly more efficacious than placebo (two way ANOVAs, p < 0.05). For pain intensity difference (PID) and pain relief, the 12.5 mg dose exhibited statistical superiority from hours 1 through 3, while the 37.5 mg dose exhibited statistical superiority from 40 minutes through 4 hours. Ketoprofen 37.5 mg was significantly more efficacious than the 12.5 mg dose only at 40 minutes for PID(VAS) and relief, and at 60 minutes for PID(VAS). Both ketoprofen dosages displayed significantly greater 3-hr, 4-hr and 6-hr summary analgesic measures (SPID(VAS), SPID(CAT), TOTPAR) than placebo, with the exception of the 6-hr SPID(CAT) measure for ketoprofen 12.5 mg. No serious side effects were observed in this study. We conclude that ketoprofen in a dose range of 12.5 mg to 37.5 mg is a safe and effective analgesic for the relief of post-operative dental pain.
Dental radiographs are critical for the complete assessment and treatment of dental diseases. Dental radiography is commonly used to evaluate congenital dental defects, periodontal disease, orthodontic manipulations, oral tumors, endodontic treatments, oral trauma, and any situation where an abnormality is suspected. Although standard radiographic equipment and film can be used to produce dental radiographs, dental X-ray equipment and film provide superior quality images and greater convenience of animal patient positioning. An understanding of normal dental radiographic anatomy is important when interpreting dental radiographs. Stage III periodontitis is the earliest stage of periodontal disease at which radiographic abnormalities become apparent. Bone loss associated with periodontal disease can be classified as either horizontal or vertical. Periapical radiolucencies can represent granulomas, cysts, or abscesses, whereas periapical radiodensities may represent sclerotic bone or condensing osteitis. Lytic lesions of the bone of the jaw often represent oral neoplasms. Neoplasms also can displace or disrupt teeth in the dental arch. Resorptive lesions can be external or internal and appear as radiolucent areas involving the external surface of the root or the pulp cavity, respectively. Feline dental resorptive lesions, also known as odontoclastic resorptions, are a specific form of dental resorptive lesions unique to cats.

Our objective was to evaluate whether there is an association with the different levels of dental fluorosis and the presence of dental trauma amongst school children. A transversal study was conducted amongst school children from the age of 12. Dental examinations were conducted by 24 well trained and fully qualified dental surgeons. Data was collected from 36 randomly selected public schools amongst 89 schools in a municipality. The criteria used to diagnose dental fluorosis was based on the Dean's fluorosis Index and for diagnosing dental trauma we looked for clinical signs of crown fractures and dental avulsions. Multiple descriptive analysis, which was bivariate, was carried out. Amongst the 2,755 school children that took part in the study 1,089 (39.6%) were diagnosed with dental fluorosis and 106 (3.8%) had one tooth or more with dental trauma. We noted a high prevalence of dental fluorosis, independent of the level of severity, amongst individuals with one tooth or more who had dental trauma. This association was even more evident where there were severely high levels of fluorosis. We also noted that the presence of fluorosis was greater amongst those that actively paid more attention to discoloration on their teeth and who received treatment from a dental professional at their schools. Nevertheless dental fluorosis was associated with the presence of dental trauma, independent of its severity.

To examine prenatal dental care needs, utilization and oral health counseling among Maryland women who delivered a live infant during 2001-2003 and identify the factors associated with having a dental visit and having an unmet dental need during pregnancy. Pregnancy Risk Assessment Monitoring System is an ongoing population based surveillance system that collects information of women's attitudes and experiences before, during, and shortly after pregnancy. Logistic regression was used to model dental visits and unmet dental need using predictor variables for Maryland 2001-2003 births. Less than half of all women reported having a dental visit and receiving oral health advice during pregnancy. Twenty-five percent of women reported a need for dental care, of which 33 % did not receive dental care despite their perceived need. Multivariate modeling revealed that racial minorities, women who were not married and those with annual income <$40,000 were least likely to have a dental visit. Women who were not married, had low annual income, were older than 40 years of age, had an unintended pregnancy and received prenatal care later than desired were most likely to have an unmet dental need during pregnancy. Despite reported needs and existing recommendations to include oral health as a component of prenatal care, less than half of pregnant women have a dental visit during their pregnancy. One-third of women with a dental problem did not have a dental visit highlighting the unmet need for dental care during pregnancy.

A new universal graphic dental system, Forensic Dental Symbols(©), has been created to provide precision in the construction of dental records, improve standardization, and increase efficiency in dental identification procedures. Two hundred and thirty-four different graphic symbols representing the most frequent clinical status for each tooth were designed. Symbols can be then converted to a typographic font and then are ready to use in any computer. For the appropriate use, manipulation, and storage of dental information generated by the Forensic Dental Symbols(©), Dental Encoder(©) database has been created. The database contains all the information required by INTERPOL Disaster Victim Identification (DVI)-dental-forms. To explore the possibilities that Dental Encoder(©) offers, an antemortem dental database from a Spanish population of 3920 military personnel had been constructed. Data generated by Dental Encoder(©) were classified into sex and age groups. The program can perform an automatic search of the database for cases that match a selected clinical status presented in a single tooth or a combination of situations for several teeth. Moreover, Dental Encoder(©) allows information to be printed on INTERPOL DVI-dental-forms, or the inclusion of any completed form into any document, technical report, or identification of dental report.

Extraction of 14 teeth in six patients taking dicumarol caused no unusual bleeding. Discontinuance of dicumarol prior to dental extraction should not necessarily be a routine procedure; in certain persons with a demonstrated strong tendency to recurrent thrombosis, dicumarol should be continued, based on the decision that the danger of clotting without the drug is greater than the danger of bleeding with the drug.

This paper reviews past and present applications of quantitative and molecular genetics to dental disorders. Examples are given relating to craniofacial development (including malocclusion), oral supporting tissues (including periodontal diseases) and dental hard tissues (including defects of enamel and dentine as well as dental caries). Future developments and applications to clinical dentistry are discussed. Early investigations confirmed genetic bases to dental caries, periodontal diseases and malocclusion, but research findings have had little impact on clinical practice. The complex multifactorial aetiologies of these conditions, together with methodological problems, have limited progress until recently. Present studies are clarifying previously unrecognized genetic and phenotypic heterogeneities and attempting to unravel the complex interactions between genes and environment by applying new statistical modelling approaches to twin and family data. Linkage studies using highly polymorphic DNA markers are providing a means of locating candidate genes, including quantitative trait loci (QTL). In future, as knowledge increases; it should be possible to implement preventive strategies for those genetically-predisposed individuals who are identified to be at risk.

There has been, and still is a firm belief that regular use of dental services is beneficial for all. Thus governments in most European countries have shown some interest in training oral health care professionals, distributing the dental workforce and cost sharing. Constantly evolving treatment options and the introduction of new methods make dental clinicians feel uncertain as to which treatments are most useful, who would benefit from them, and which treatments will achieve cost-effective health gain. Although there is a considerable quantity of scientific literature showing that most available preventive measures are effective, and the number of sensible best-practice guidelines in prevention is growing, there are few studies on cost-efficiency of different methods and, secondly, the prevention and treatment guidelines are poorly known among general practitioners. In the eyes of the public, it is obvious that preventive methods practised by patients at home have been eclipsed by clinical procedures performed in dental clinics. Reliance on an increasingly individualistic approach to health care leads to the medicalisation of issues that are not originally health or medical problems. It is important to move general oral disease prevention back to the people who must integrate this in their daily routines. Prevention primarily based on healthy lifestyles, highlighted in the new public health strategy of the European Union (EU), is the key to future health policy.

Dental coverage for adult enrollees is an optional benefit under Medicaid. Thirty-one states and the District of Columbia have expanded eligibility for Medicaid under the Affordable Care Act. Millions of low-income adults have gained health care coverage and, in states offering dental benefits, oral health coverage as well. Using data for 2010 and 2014 from the Behavioral Risk Factor Surveillance System, we examined the impact of Medicaid adult dental coverage and eligibility expansions on low-income adults' use of dental care. We found that low-income adults in states that provided dental benefits beyond emergency-only coverage were more likely to have had a dental visit in the past year, compared to low-income adults in states without such benefits. Among states that provided dental benefits and expanded their Medicaid program, regression-based estimates suggest that childless adults had a significant increase (1.8 percentage points) in the likelihood of having had a dental visit, while parents had a significant decline (8.1 percentage points). One possible explanation for the disparity is that after expansion, newly enrolled childless adults might have exhausted the limited dental provider capacity that was available to parents before expansion. Additional policy-level efforts may be needed to expand the dental care delivery system's capacity.

Drug therapy in dentistry is essential for patients' treatment and requires special care by dentists, so it must be part of a well-grounded education for predoctoral dental students. The aim of this study was to evaluate the knowledge of undergraduate students at dental schools in Brazil about the use of drugs in dental practice. The sample universe was comprised of all undergraduates enrolled in the last year of the dentistry course in three universities in 2010 (n=253). Inclusion criteria were students in their last year of enrollment and who agreed to participate in the research. The results were analyzed on Epi Info 3.5.1 software. Analyses were conducted with chi-square, Friedman, and Wilcoxon tests. Slightly more than half of the participants (51.9 percent) reported the ideal dose of anesthetic for a normal patient. However, their difficulties increased when asked about the relationship between the anesthetic and patients with systemic disease or those needing special care. Regarding drugs that usually cause allergic attack, only 29.2 percent and 36.6 percent, respectively, cited methyl methacrylate and latex. This study found that the knowledge of these undergraduates about the questions was deficient, so dental education should include more theoretical and clinical practice in recognizing the patient's medical needs.

Background: The present study aimed to assess potential correlation between dental anxiety and overall dental status in adult patients, in consideration of the frequency of dental appointments and individual dental hygiene practices. Materials and Methods: Individual dental anxiety levels were assessed with the aid of the Corah’s dental anxiety scale (DAS). The study embraced 112 patients of the University Dental Clinic, Kraków. Following clinical and X-ray exams, respectively, decayed, missing and filled teeth (DMFT) index and dental treatment index (DTI) were computed for each study subject. Results: Mean DAS among the 112 subjects under study was 9.41 standard deviation (SD = 3.36). Mean DMFT value was 15.86 (SD = 7.00), whereas DTI value was 0.76 (SD = 0.27). The number of decayed teeth and an individual dental anxiety level were found to be correlated (r = 0.26). Higher dental anxiety correlated with lower DTI value (r = −0.22) and lesser frequency of dental appointments (r = 0.22). Conclusions: Individual dental anxiety level appears to impact overall dental status, frequency of dental appointments and everyday oral health practices. Every conceivable effort should therefore be undertaken with a view to effectively diminishing dental anxiety levels in the patients.

At the bud stage of tooth development the neural crest derived mesenchyme condenses around the dental epithelium. As the tooth germ develops and proceeds to the cap stage, the epithelial cervical loops grow and appear to wrap around the condensed mesenchyme, enclosing the cells of the forming dental papilla. We have fate mapped the dental mesenchyme, using in vitro tissue culture combined with vital cell labelling and tissue grafting, and show that the dental mesenchyme is a much more dynamic population then previously suggested. At the bud stage the mesenchymal cells adjacent to the tip of the bud form both the dental papilla and dental follicle. At the early cap stage a small population of highly proliferative mesenchymal cells in close proximity to the inner dental epithelium and primary enamel knot provide the major contribution to the dental papilla. These cells are located between the cervical loops, within a region we have called the body of the enamel organ, and proliferate in concert with the epithelium to create the dental papilla. The condensed dental mesenchymal cells that are not located between the body of the enamel organ, and therefore are at a distance from the primary enamel knot, contribute to the dental follicle, and also the apical part of the papilla, where the roots will ultimately develop. Some cells in the presumptive dental papilla at the cap stage contribute to the follicle at the bell stage, indicating that the dental papilla and dental follicle are still not defined populations at this stage. These lineage-tracing experiments highlight the difficulty of targeting the papilla and presumptive odontoblasts at early stages of tooth development. We show that at the cap stage, cells destined to form the follicle are still competent to form dental papilla specific cell types, such as odontoblasts, and produce dentin, if placed in contact with the inner dental epithelium. Cell fate of the dental mesenchyme at this stage is therefore determined

Routine dental examinations for children are important for early diagnosis and treatment of dental problems. The level of dental morbidity among Israeli children is higher than the global average. A July 2010 reform of Israel's National Health Insurance Law gradually offers free dental services for children up to age 12. The study examines the use of dental services for children and the factors affecting mothers' decision to take their children for routine checkups. In addition, the study examines the impact of the reform on dental checkups for children in various populations groups. A national representative sample comprising 618 mothers of children aged 5-18 was surveyed by telephone. The survey integrated the principles of the health beliefs model and socio-demographic characteristics. The results show that mothers' decision to take their children for dental checkups is affected by their socio-demographic status and by their health beliefs with respect to dental health. After the reform, the frequency of children's dental checkups significantly increased among vulnerable populations. Therefore, the reform has helped reduce gaps in Israeli society regarding children's dental health. Raising families' awareness of the reform and of the importance of dental health care together with expanding national distribution of approved dental clinics can increase the frequency of dental checkups among children in Israel.
Context: Child dental neglect is a terrible tragedy with a high prevalence. Dealing with this issue is important regarding psychological and physical health policies. The current review was conducted to provide health professionals insight into the different aspects of child dental neglect as reported in previous literature. Evidence Acquisition: Our review was prepared through an electronic search using Pub Med, Science Direct, Medline, Google, Cochran Library, Google Scholar and EMBASE databases. Relevant papers published since 2000 until now in English, discussing child dental neglect were retrieved. Both original and review papers were included. Eligible articles were fully read by the author. A data form was used to record useful findings. Results: Distinguishing the direct and indirect signs of dental neglect is the first step for improvement of this matter. The dental team are the main professionals who can improve parental knowledge about the consequences of child dental neglect. Victims suffer from short and long-term adverse outcomes. Collaborative attempts need to be made by different health professionals to deal with this problem. Conclusions: Child dental neglect has many long-term impacts. The main professionals who are responsible for identification, intervention and treatment of child dental neglect are dental practitioners. However, other professionals cannot ignore this task. Finally, child dental neglect, despite its derivative outcomes, may be a presentation of a broader maltreatment. PMID:25741483

A prerequisite dental evaluation is usually recommended for potential organ transplant candidates. This is based on the premise that untreated dental disease may pose a risk for infection and sepsis, although there is no evidence that this has occurred in organ transplant candidates or recipients. The purpose of this study was to assess the prevalence of dental disease and oral health behaviors in a sample of liver transplant candidates (LTCs). Oral examinations were conducted on 300 LTCs for the presence of gingivitis, dental plaque, dental caries, periodontal disease, edentulism, and xerostomia. The prevalence of these conditions was compared with oral health data from national health surveys and examined for possible associations with most recent dental visit, smoking, and type of liver disease. Significant risk factors for plaque-related gingivitis included intervals of more than 1 yr since the last dental visit (P = 0.004), smoking (P = 0.03), and diuretic therapy (P = 0.005). Dental caries and periodontal disease were also significantly associated with intervals of more than 1 yr since the last dental visit (P = 0.004). LTCs with viral hepatitis or alcoholic cirrhosis had the highest smoking rate (78.8%). Higher rates of edentulism occurred among older LTCs who were less likely to have had a recent dental evaluation (mean 88 months). In conclusion, intervals of more than 1 yr since the last dental visit, smoking, and diuretic therapy appear to be the most significant determinants of dental disease and the need for a pretransplantation dental screening evaluation in LTCs. Edentulous patients should have periodic examinations for oral cancer.

The purpose of this study was to identify core journals and the databases that provide access to these journals for the field of dental assisting. This study was completed as a part of the Medical Library Association (MLA) Nursing and Allied Health Resources Section's project to map the literature of allied health. There were three original journals selected for analysis using the prescribed methodology, Dental Assistant, the journal of the American Dental Assistants Association; Journal of the CDAA, the journal of the Canadian Dental Assistants' Association; and Dental Teamwork, published by the American Dental Association. Dental Teamwork ceased publication in December 1996; however, it was considered a necessary part of the analysis due to its extensive coverage of dental assisting as well as its numerous scientific articles with references. In Dental Assistant, there were 16 source articles, containing 206 citations. In Dental Teamwork, there were 31 source articles with 308 citations. In Journal of the CDAA, there were only 3 source articles with 14 citations. Bradford's Law of Scattering was applied to the journal citations. Four databases, MEDLINE, the Cumulative Index to Nursing and Allied Health Literature, EMBASE/Excerpta Medica, and HEALTH were analyzed for their coverage of these cited journals. This study may encourage the dental assisting profession to take a close look at its existing journals and to consider enhancing the content of these journals or the publication of additional journals in the field. Dental assistants of today need substantive literature that deals with all aspects of their chosen profession in order to meet the challenges of providing dental health care in the future.

Dental services for elderly patients are characterized by a series of particularities related to the vulnerability of this age group, which is affected by various co morbidities, and the diminished physical, cognitive and financial capacities. Finding ways to keep elderly patients coming to a dental office is possible by improving the dentist-patient relationship and implicitly the quality of care by increasing the self-esteem of the elderly and their place in society, by increasing the role of oral health in the quality of life, and here we refer to the pleasure of eating, the pleasant physical aspect and normal diction. The present paper presents the psychological aspects that interfere in the communication process between the dentist and the elderly patient and the changes motivation undergoes when people are in pain. These data can sometimes change the reticent attitude of the dentist towards the elderly patient which is often considered to be a risk patient.

Dental caries is a chronic infectious disease resulting from the penetration of oral bacteria into the enamel and dentin. Microorganisms subsequently trigger inflammatory responses in the dental pulp. These events can lead to pulp healing if the infection is not too severe following the removal of diseased enamel and dentin tissues and clinical restoration of the tooth. However, chronic inflammation often persists in the pulp despite treatment, inducing permanent loss of normal tissue and reducing innate repair capacities. For complete tooth healing the formation of a reactionary/reparative dentin barrier to distance and protect the pulp from infectious agents and restorative materials is required. Clinical and in vitro experimental data clearly indicate that dentin barrier formation only occurs when pulp inflammation and infection are minimised, thus enabling reestablishment of tissue homeostasis and health. Therefore, promoting the resolution of pulp inflammation may provide a valuable therapeutic opportunity to ensure the sustainability of dental treatments. This paper focusses on key cellular and molecular mechanisms involved in pulp responses to bacteria and in the pulpal transition between caries-induced inflammation and dentinogenic-based repair. We report, using selected examples, different strategies potentially used by odontoblasts and specialized immune cells to combat dentin-invading bacteria in vivo. PMID:26538821
Numerous written relicts, belletristic works (poems of Martial, Juvenal, Ovid etc.) indicate that oral hygiene and its tools (toothbrush, toothpick, use of tooth pastes and tooth-powder) were used long before our times. Already ancient people started to remove, file, dye and inlay teeth. The teeth were dyed red, green or black in Egypt, red or brown (with henna or betel) in India, white by Romans. The teeth decoration has a long but forgotten history. The most skillful and artistic work was done by the Maya's between 900 BC and 1500 AD. The modification of contours (more than fifty forms) of the incisors were practiced also in Mesoamerica. Dentistry was surely practiced in ancient Egypt, India, China, Greece and Rome, while odontology and especially suitable dental appliances arose only by Etruscan. Dental prosthesis, including bridges and simple retention bands were invented by the Etruscans 2500 years ago. These Etruscan bridges were worn mostly by females, suggesting that cosmetics was the principal dental concern. Some,--if not all--of the Roman and other prostheses have been purely ornamental. Orthodontic appliances are also Etruscan invention. The holes caused by caries were filled with garlic, incense, caraway seed in Egypt, with wood or lead in Rome, and with "silver-paste" (amalgam) in ancient China. The toothache was cured with poppy-tee, or hashish and nightshade plants (Solanaceae) in Egypt, Greece, Roman Empire while with coca (Erythroxylon coca) in South-America.

The acute dental abscess is frequently underestimated in terms of its morbidity and mortality. The risk of potential serious consequences arising from the spread of a dental abscess is still relevant today with many hospital admissions for dental sepsis. The acute dental abscess is usually polymicrobial comprising facultative anaerobes, such as viridans group streptococci and the Streptococcus anginosus group, with predominantly strict anaerobes, such as anaerobic cocci, Prevotella and Fusobacterium species. The use of non-culture techniques has expanded our insight into the microbial diversity of the causative agents, identifying such organisms as Treponema species and anaerobic Gram-positive rods such as Bulleidia extructa, Cryptobacterium curtum and Mogibacterium timidum. Despite some reports of increasing antimicrobial resistance in isolates from acute dental infection, the vast majority of localized dental abscesses respond to surgical treatment, with antimicrobials limited to spreading and severe infections. The microbiology and treatment of the acute localized abscess and severe spreading odontogenic infections are reviewed.

A polarization sensitive optical imaging system is used to detect changes in polarization in dental tissues to aid the diagnosis of dental disease such as caries. The degree of depolarization is measured by illuminating the dental tissue with polarized light and measuring the polarization state of the backscattered light. The polarization state of this reflected light is analyzed using optical polarimetric imaging techniques. A hand-held fiber optic dental probe is used in vivo to direct the incident beam to the dental tissue and collect the reflected light. To provide depth-resolved characterization of the dental tissue, the polarization diagnostics may be incorporated into optical coherence domain reflectometry and optical coherence tomography (OCDR/OCT) systems, which enables identification of subsurface depolarization sites associated with demineralization of enamel or bone.

Dental wear is loss of tooth structure resulting from erosion, attrition, abrasion and, possibly, abfraction. Clinical/experimental data suggest no single damaging mechanism, but rather simultaneous interaction of these destructive processes. The most important interaction is abrasion/attrition potentiated by dental erosion. Awareness of this pathosis is not well-appreciated by the public and dental professionals because the signs may be subtle. This article focuses on recognizing, diagnosing and managing dental wear. Dental wear is a challenging problem for clinicians because of the subtlety of early changes; confusion about the etiology of the problem; and the dilemma of when or how to manage the etiology. Unfortunately, failure to recognize and manage the process often results in inaction until the breakdown is severe. At that point, the structural breakdown is so advanced that major rehabilitative treatment often is needed. This introductory article discusses diagnosing and managing dental wear.

This his article reports the findings of a study conducted to investigate the personality types of Chinese dental school applicants. The Chinese version of the Myers-Briggs Type Indicator (MBTI) (Form G) was used to assess the personality styles of 332 dental school applicants from the mainland of China. The results of the MBTI for Chinese dental school applicants were compared with a previous study of applicants from the U.K. A higher percentage of this group of Chinese applicants scored higher for Introversion (I) than Extroversion (E); both Chinese and English applicants preferred Judging (J) to Perceiving (P). The dominant personality types in Chinese applicants were ISTJ, ESTJ, and ISFP. The findings suggest that the personality types of Chinese dental students may be somewhat different from the personality profiles exhibited by dental students from other nations. The findings may be of value to individuals who desire to investigate personality type differences among dental students with different cultural backgrounds.

For many years, dental technicians were largely self-regulated and left to work without any undue interference from, or legislation by, outside authorities. This situation has changed somewhat dramatically in recent years, primarily as a result of a) mandatory General Dental Council (GDC) registration of UK-based dental technicians and b) the requirement to comply with certain EC directives governing the provision of dental appliances. There seems to be some confusion, however, about these various changes and the ensuing ramifications for dental practitioners. The purpose of this paper is firstly to clarify the various regulatory issues currently surrounding technician registration and the provision of laboratory work ('Made in Britain' or otherwise) and secondly to explore the various internationally-recognised quality assurance standards that can be applied to the production of such work in order to assist dentists in gauging quality-related claims made by dental laboratories, both in the UK and overseas.

This paper describes the Orthoscope, an equipment for acquisition, processing, and archiving of images of patients mouth or skin. The equipment can capture and process images of single tooth, group of teeth or the whole dental arc. A dentist can easily observe the situation in mouth, demonstrate intended plan of treatment to patient and document its results. A dermatologist can evaluate treatment progress. Unlike other methods, our device shows geometrically undistorted calibrated image.The presented equipment is intended for daily practice. The image processing module is connected to an insurance office system and medical archives. This eliminates time consuming literal description of the patient dental/dermatological status. The images can be used later checking of the diagnosis and treatment.

Soft skills and hard skills are essential in the practice of dentistry. While hard skills deal with technical proficiency, soft skills relate to a personal values and interpersonal skills that determine a person's ability to fit in a particular situation. These skills contribute to the success of organisations that deal face-to-face with clients. Effective soft skills benefit the dental practice. However, the teaching of soft skills remains a challenge to dental schools. This paper discusses the different soft skills, how they are taught and assessed and the issues that need to be addressed in their teaching and assessment. The use of the module by the Faculty of Dentistry, University of Malaya for development of soft skills for institutions of higher learning introduced by the Ministry of Higher Education, Malaysia.

Dental anomalies can be classified in different groups: anomalies of volume, anomalies of number, anomalies of form, anomalies of position and anomalies by union. Of the latter, we distinguish between fusion, alveolus-dental gemination, concrescence, coalescence and anchylosis. Gemination is more frequent in the anterior teeth, although it can also affect the bicuspids and molars, being an anomaly of infrequent union (prevalence 0.5%). We present the case of a young male patient age 19, without medical antecedents of interest, that goes to consultation for repeated inflammatory accidents at level of the inferior left retromolar area. These episodes are caused by a semi-impacted inferior third molar that is fused to a supernumerary fourth molar, sharing its roots, crown, pulp chambers and canals. After the appropriate radiologic study and suitable planning, the semi-impacted third molar was extracted under local anaesthesia and without any other complications during or after the operation.

The conclusions drawn from the study of an oral biopsy are considered essential for the definitive diagnosis of diseases of the oral mucosa, and for the subsequent planning of appropriate treatment. Although the obtainment of biopsies is widely used in all medical fields, the practice is not so widespread in dental practice--fundamentally because of a lack of awareness of the procedure among dental professionals. In this context, it must be taken into account that the early diagnosis of invasive oral malignancy may be critical for improving the patient prognosis. However, in some cases the results are adversely affected by incorrect manipulation of the biopsy material. The present study provides an update on the different biopsy sampling techniques and their application. Such familiarization in turn will contribute to knowledge of the material and instruments required for correct biopsy performance in dentistry, as well as of the material required for correct sample storage and transport.

In orthodontics the relation between the force (natural or artificial) and the structures that must be modified or led towards a normal situation is in fact a complex equation would multiple aspects determined by the biological part. The orthodontic forces imply, both in action as in effect, all the elements of the dental system, meaning bones, teeth, periodontal tissue. On the other side, the structures of the dental system may help, limit ate, or even erase the action of the orthodontic forces. Our article brings into discussion the relation between the teeth' sustaining structures and their movements determined by the orthodontic forces both as a reaction to a therapeutical treatment and as their direct implication into the result and the stability of the orthodontic treatment, on a long-term.

In existence for more than 100 years, the schools of medicine and dentistry of Howard University and Meharry Medical College have been responsible for training the majority of African-American physicians and dentists. The dissolution of the doctrine of "separate but equal" has resulted in the acceptance of larger numbers of African-American health professionals to America's medical and dental educational institutions. The University of Tennessee School of Dentistry is a primary example of a formerly segregated institution that has changed its policies and presently possesses a respectable number of African-American dental alumni. In a recent acknowledgment of this fact on Alumni Day, black graduates of this University celebrated and sponsored a program to increase the number of African-American matriculants at the school.

Dental fluorosis occurs as a result of excess fluoride ingestion during tooth formation. Enamel fluorosis and primary dentin fluorosis can only occur when teeth are forming, and therefore fluoride exposure (as it relates to dental fluorosis) occurs during childhood. In the permanent dentition, this would begin with the lower incisors, which complete mineralization at approximately 2-3 years of age, and end after mineralization of the third molars. The white opaque appearance of fluorosed enamel is caused by a hypomineralized enamel subsurface. With more severe dental fluorosis, pitting and a loss of the enamel surface occurs, leading to secondary staining (appearing as a brown color). Many of the changes caused by fluoride are related to cell/matrix interactions as the teeth are forming. At the early maturation stage, the relative quantity of amelogenin protein is increased in fluorosed enamel in a dose-related manner. This appears to result from a delay in the removal of amelogenins as the enamel matures. In vitro, when fluoride is incorporated into the mineral, more protein binds to the forming mineral, and protein removal by proteinases is delayed. This suggests that altered protein/mineral interactions are in part responsible for retention of amelogenins and the resultant hypomineralization that occurs in fluorosed enamel. Fluoride also appears to enhance mineral precipitation in forming teeth, resulting in hypermineralized bands of enamel, which are then followed by hypomineralized bands. Enhanced mineral precipitation with local increases in matrix acidity may affect maturation stage ameloblast modulation, potentially explaining the dose-related decrease in cycles of ameloblast modulation from ruffle-ended to smooth-ended cells that occur with fluoride exposure in rodents. Specific cellular effects of fluoride have been implicated, but more research is needed to determine which of these changes are relevant to the formation of fluorosed teeth. As further

Fifty-three patients were examined for dental abnormalities at an institution specializing in care of the mentally deficient in Bauru, São Paulo State. The incidence of teeth with abnormal morphology, mainly second molars with an abnormal number of cusps, was extremely high. Enamel hypoplasia was frequently found in anterior teeth, and the percentage of fractured maxillary incisors was significantly higher than that observed in normal individuals.

Sports drinks were originally developed to improve hydration and performance in athletes taking part in intense or endurance sporting events. These drinks contain relatively high amounts of carbohydrates (sugars), salt, and citric acid. These ingredients create the potential for dental ramifications and overall public health consequences such as obesity and diabetes. High intake of sports drinks during exercise, coupled with xerostomia from dehydration, may lead to the possibility of erosive damage to teeth.

Five dental alloys, on exposure to blood and chocolate media with and without inoculated microorganisms, showed varying degrees of tarnish. The results indicated a composition-dependent tarnish behavior of alloys in microorganism-inoculated media, indicating a potential role for the oral microorganisms in inducing clinically observed tarnish of dental alloys. Actinomyces viscosus and periodontal pocket specimens show a similarity in their activity to induce tarnish in base metal-containing dental alloys.

This study examined the impact of expanded function allied dental personnel on the productivity and efficiency of general dental practices. Detailed practice financial and clinical data were obtained from a convenience sample of 154 general dental practices in Colorado. In this state, expanded function dental assistants can provide a wide range of reversible dental services/procedures, and dental hygienists can give local anesthesia. The survey identified practices that currently use expanded function allied dental personnel and the specific services/procedures delegated. Practice productivity was measured using patient visits, gross billings, and net income. Practice efficiency was assessed using a multivariate linear program, Data Envelopment Analysis. Sixty-four percent of the practices were found to use expanded function allied dental personnel, and on average they delegated 31.4 percent of delegatable services/procedures. Practices that used expanded function allied dental personnel treated more patients and had higher gross billings and net incomes than those practices that did not; the more services they delegated, the higher was the practice's productivity and efficiency. The effective use of expanded function allied dental personnel has the potential to substantially expand the capacity of general dental practices to treat more patients and to generate higher incomes for dental practices.

Dental professionals are predisposed to a number of occupational hazards. These include exposure to infections (including Human Immunodeficiency Virus and viral hepatitis); percutaneous exposure incidents, dental materials, radiation, and noise; musculoskeletal disorders; psychological problems and dermatitis; respiratory disorders; and eye insults. Percutaneous exposure incidents remain a main concern, as exposure to serious infectious agents is a virtual risk. Minimizing percutaneous exposure incidents and their consequences should continue to be considered, including sound infection control practices, continuing education, and hepatitis B vaccination. Basically, for any infection control strategies, dentists should be aware of individual protective measures and appropriate sterilization or other high-level disinfection utilities. Strained posture at work disturbs the musculoskeletal alignment and leads to stooped spine. The stooped posture also involved certain groups of muscles and joints. This may lead to diseases of the musculoskeletal system. Continuous educating and appropriate intervention studies are needed to reduce the complication of these hazards. So, it is important for dentists to remain constantly up-to-date about measures on how to deal with newer strategies and dental materials, and implicates the need for special medical care for this professional group.

Actinic cheilitis is a potentially premalignant condition involving predominantly the vermilion of the lower lip. The aim of the current paper was to review the clinical presentation of actinic cheilitis and demonstrate the development of management plans using a series of cases. These are designed to provide immediate treatment where required but also to address the medium and long-term requirements of the patient. The authors suggest that the clinical examination of lips and the assessment of actinic cheilitis and other lip pathology become a regular part of the routine soft tissue examination undertaken as a part of the periodic examination of dental patients. Early recognition of actinic cheilitis can allow the development of strategies for individual patients that prevent progression. These are based on past sun exposure, future lifestyle changes and the daily use of emollient sunscreens, broad-brimmed hats and avoidance of sun exposure during the middle of the day. This is a service that is not undertaken as a matter of routine in general medical practice as patients are not seen with the regularity of dental patients and generally not under the ideal examination conditions available in the dental surgery.

Dental xeroradiography is a high-quality intraoral imaging system which provides a potentially convenient, rapid, low-dose alternative to conventional film radiography. In this study the sensitometric properties of dental xeroradiography were investigated via assessment of high- and low-contrast xeroradiographic processor settings, transmission versus reflection densitometry, reciprocity-law failure, and kVp (tube voltage) plate dependence. Findings of the study indicated that imaging at high-contrast processor settings results in greater dynamic range but less exposure latitude than imaging at low-contrast processor settings. Determination of characteristic curves demonstrated greater contrast in reflection mode than imaging by transillumination for all but the very densest of images (greater than 1.6 O.D.). There was also little difference in characteristic curves produced from 50 to 90 kVp, indicating that the xeroradiographic plate exhibits a relatively constant sensitivity over the tube voltages tested if exposure is expressed in roentgens. Finally, no substantial reciprocity-law failure was observed for dental xeroradiography over a clinically relevant range of exposure times.

On 12 May 2008, an earthquake with a magnitude of 8.0 on the Richter scale hit Wenchuan, China. In the aftermath of this natural disaster, Chinese dental professionals actively participated in the first emergency medical response team, definitive dental treatment, oral health services and education, and the recovery of local oral care infrastructure and resources. Learning from the experience and first-hand data of the Wenchuan earthquake, dental professionals can increase their awareness of the importance of collaborative emergency response health services in mass casualty events. Further research and emphasis is needed to encourage the participation of dental professionals in disaster preparation training and practice.

The goal of an infection control program is to provide a safe working environment for dental health care personnel and their patients. Practitioners can achieve this by adopting measures that reduce health care-associated infections among patients and occupational exposures among dental health care personnel. It is crucial for all dental practitioners to be up to date on current Centers for Disease Control and Prevention guidelines, equipment, and techniques for proper infection control. Continuous evaluation of infection control practices is important. Patients and dental providers should be confident that oral health care can be delivered and received in a safe manner.

Dental caries remains a significant public health problem and is considered pandemic worldwide. The prediction of dental caries based on profiling of microbial species involved in disease and equally important, the identification of species conferring dental health has proven more difficult than anticipated due to high interpersonal and geographical variability of dental plaque microbiota. We have used RNA-Seq to perform global gene expression analysis of dental plaque microbiota derived from 19 twin pairs that were either concordant (caries-active or caries-free) or discordant for dental caries. The transcription profiling allowed us to define a functional core microbiota consisting of nearly 60 species. Similarities in gene expression patterns allowed a preliminary assessment of the relative contribution of human genetics, environmental factors and caries phenotype on the microbiota's transcriptome. Correlation analysis of transcription allowed the identification of numerous functional networks, suggesting that inter-personal environmental variables may co-select for groups of genera and species. Analysis of functional role categories allowed the identification of dominant functions expressed by dental plaque biofilm communities, that highlight the biochemical priorities of dental plaque microbes to metabolize diverse sugars and cope with the acid and oxidative stress resulting from sugar fermentation. The wealth of data generated by deep sequencing of expressed transcripts enables a greatly expanded perspective concerning the functional expression of dental plaque microbiota. PMID:25177549

Today proper selection of dental cements is a key factor to achieve a successful restoration and will greatly increase the chances of long-term success of the restoration. In recent years, many newly formulated dental cements have been developed with the claim of better performance compared to the traditional materials. Unfortunately, selection of suitable dental cement for a specific clinical application has become increasingly complicated, even for the most experienced dentists. The purpose of this article is to review the currently existing dental cements and to help the dentists choose the most suitable materials for clinical applications.
The American Dental Trade Association Managed Care Task Force has provided an extensive study of the effects of reimbursement on the dental profession and the dental trade industry. There is great variety among the needs of patients and in the reimbursement plans available. ADTA is urged to take a leadership position to ensure that programs do not restrict access, value, or quality. The key to this strategy will be communicating a consistent message to dentists, patients, benefit managers, and the research community. The message is: "Responsible consumption of appropriate dental services."

Changes in normal equine dental anatomy with age result in dental disease specific to the geriatric horse. The culmination of dental disease throughout the life of a horse often results in advanced dental disease. Treatment of specific dental disease conditions has to be adapted for older horses to compensate for reduction in reserve crown and occlusal enamel. Ensuring oral comfort and maximizing masticatory ability are the mainstays of geriatric dental treatment. Recognition of dental disease common to older horses ensures that correct treatment is applied. Older patients often require long-term management changes, such as dietary modification, to manage dental disease effectively.

Virtual autopsy is a medical imaging technique, using full body computed tomography (CT), allowing for a noninvasive and permanent observation of all body parts. For dental identification clinically and radiologically observed ante-mortem (AM) and post-mortem (PM) oral identifiers are compared. The study aimed to verify if a PM dental charting can be performed on virtual reconstructions of full-body CT's using the Interpol dental codes. A sample of 103 PM full-body CT's was collected from the forensic autopsy files of the Department of Forensic Medicine University Hospitals, KU Leuven, Belgium. For validation purposes, 3 of these bodies underwent a complete dental autopsy, a dental radiological and a full-body CT examination. The bodies were scanned in a Siemens Definition Flash CT Scanner (Siemens Medical Solutions, Germany). The images were examined on 8- and 12-bit screen resolution as three-dimensional (3D) reconstructions and as axial, coronal and sagittal slices. InSpace(®) (Siemens Medical Solutions, Germany) software was used for 3D reconstruction. The dental identifiers were charted on pink PM Interpol forms (F1, F2), using the related dental codes. Optimal dental charting was obtained by combining observations on 3D reconstructions and CT slices. It was not feasible to differentiate between different kinds of dental restoration materials. The 12-bit resolution enabled to collect more detailed evidences, mainly related to positions within a tooth. Oral identifiers, not implemented in the Interpol dental coding were observed. Amongst these, the observed (3D) morphological features of dental and maxillofacial structures are important identifiers. The latter can become particularly more relevant towards the future, not only because of the inherent spatial features, yet also because of the increasing preventive dental treatment, and the decreasing application of dental restorations. In conclusion, PM full-body CT examinations need to be implemented in the

Background Attitudes and views are critical to the adoption of innovation. While there have been broadening calls for a standardized dental diagnostic terminology, little is known about the views of private practice dental team members towards the adoption of such a terminology. Methods A survey was developed using validated questions identified through literature review. Domain experts’ input allowed for further modifications. The final survey was administered electronically to 814 team members at a multi-office practice based in the Pacific Northwest. Results Response proportion was 92%. The survey had excellent reliability (Cronbach alpha coefficient = 0.87). Results suggested that participants showed, in general, positive attitudes and beliefs towards using a standardized diagnostic terminology in their practices. Additional written comments by participants highlighted the potential for improved communication with use of the terminology. Conclusions Dental providers and staff in one multi-office practice showed positive attitudes towards the use of a diagnostic terminology, specifically they believed it would improve communication between the dentist and patient as well as among providers, while expressing some concerns if using standardized dental diagnostic terms helps clinicians to deliver better dental care. Practical Implications As the dental profession is advancing towards the use of standardized diagnostic terminologies, successful implementation will require that dental team leaders prepare their dental teams by gauging their attitude toward the use of such a terminology.

Objectives. We examined the ways in which levels of preventive dental care and unmet dental needs varied among subgroups of low-income children. Methods. Data were drawn from the 2002 National Survey of America’s Families. We conducted bivariate and multivariate analyses, including logistic regression analyses, to assess relationships between socioeconomic, demographic, and health factors and receipt of preventive dental care and unmet dental needs. Results. More than half of low-income children without health insurance had no preventive dental care visits. Levels of unmet dental needs among low-income children who had private health insurance coverage but no dental benefits were similar to those among uninsured children. Children of parents whose mental health was rated as poor were twice as likely to have unmet dental needs as other children. Conclusions. Additional progress toward improving the dental health of low-income children depends on identifying and responding to factors limiting both the demand for and the supply of dental services. In particular, it appears that expanding access to dental benefits is key to improving the oral health of this population. PMID:16043667

Dental coverage for adults is an elective benefit under Medicaid. As a result of budget constraints, California Medicaid eliminated its comprehensive adult dental coverage in July 2009. We examined the impact of this policy change on emergency department (ED) visits by Medicaid-enrolled adults for dental problems in the period 2006-11. We found that the policy change led to a significant and immediate increase in dental ED use, amounting to more than 1,800 additional dental ED visits per year. Young adults, members of racial/ethnic minority groups, and urban residents were disproportionately affected by the policy change. Average yearly costs associated with dental ED visits increased by 68 percent. The California experience provides evidence that eliminating Medicaid adult dental benefits shifts dental care to costly EDs that do not provide definitive dental care. The population affected by the Medicaid adult dental coverage policy is increasing as many states expand their Medicaid programs under the ACA. Hence, such evidence is critical to inform decisions regarding adult dental coverage for existing Medicaid enrollees and expansion populations.

The aim of this research was to investigate the quality of written prosthetic prescriptions provided by fourth-year dental students to a commercially operated dental laboratory and to ascertain the contribution of interprofessional education to improving prescription quality. Based on guidelines established by the Medicines and Healthcare Products Regulatory Agency of the European Union (Medical Device Directive 93/42/EEC), an audit was conducted prior to and after an educational intervention was delivered by a dental technician to a dental student cohort at one Australian dental school. Prior to the intervention, thirty-nine dental prosthetic prescriptions were collected, analyzed, and audited to determine the clarity of written communication and instructions from dental student to dental technician. Following the intervention, a further forty prosthetic prescriptions were collected from the same cohort of students and were audited. The audit of the initial prescriptions showed that 85 percent (n=33) did not comply with the recommended conventions. After the intervention, the prescriptions that did not meet the guidelines had fallen to 30 percent (n=12) of the total. Improvements in prosthetic prescriptions submitted by these dental students to the commercial dental laboratory suggest there is an advantage to including a prosthetic prescription-writing module in dental school curricula.

The Dental Pipeline Program grew out of work at the Columbia University College of Dental Medicine in the 1990s designed to address access to oral healthcare needs in New York City. Since then the Robert Wood Johnson Foundation, the W. K. Kellogg Foundation, and The California Endowment have combined to fund the largest dental education program in history. The Dental Pipeline Program has involved 23 dental schools in two phases. The goal of the program is to address issues of access (a) by providing dental care with volunteers in communities in need, (b) by seeking either full- or part-time positions in community health facilities, and (c) by preparing dentists to be advocates for the needs of the underserved. This is a preliminary report of the types of curricular changes that have been introduced and some promising results in terms of oral health care provided, minority enrollments in dental schools, and expressed intentions to practice in underserved areas.

The dentitions of lamniform sharks are said to exhibit a unique heterodonty called the "lamnoid tooth pattern." The presence of an inflated hollow "dental bulla" on each jaw cartilage allows the recognition of homologous teeth across most modern macrophagous lamniforms based on topographic correspondence through the "similarity test." In most macrophagous lamniforms, three tooth rows are supported by the upper dental bulla: two rows of large anterior teeth followed by a row of small intermediate teeth. The lower tooth row occluding between the two rows of upper anterior teeth is the first lower anterior tooth row. Like the first and second lower anterior tooth rows, the third lower tooth row is supported by the dental bulla and may be called the first lower intermediate tooth row. The lower intermediate tooth row occludes between the first and second upper lateral tooth rows situated distal to the upper dental bulla, and the rest of the upper and lower tooth rows, all called lateral tooth rows, occlude alternately. Tooth symmetry cannot be used to identify their dental homology. The presence of dental bullae can be regarded as a synapomorphy of Lamniformes and this character is more definable than the "lamnoid tooth pattern." The formation of the tooth pattern appears to be related to the evolution of dental bullae. This study constitutes the first demonstration of supraspecific tooth-to-tooth dental homologies in nonmammalian vertebrates.

The aim of this in vitro study was to compare the actual torque of 2 manual wrench systems to their stated (target) torque. New spring- (Nobel Biocare USA, LLC) and friction-style (Zimmer Dental, Inc.) manual dental torque wrenches, as well as spring torque wrenches that had undergone sterilization and clinical use, were tested. A calibrated torque gauge was used to compare actual torque to target torque values of 15 and 35 N/cm. Data were statistically analyzed via mixed-effects regression model with Bonferroni correction. At a target torque of 15 N/cm, the mean torque of new spring wrenches (13.97 N/cm; SE, 0.07 N/cm) was significantly different from that of used spring wrenches (14.94 N/cm; SE, 0.06 N/cm; P < 0.0001). However, the mean torques of new spring and new friction wrenches (14.10 N/cm; SE, 0.07 N/cm; P = 0.21) were not significantly different. For torque measurements calibrated at 35 N/cm, the mean torque of new spring wrenches (35.29 N/cm; SE, 0.10 N/cm) was significantly different (P < 0.0001) from the means of new friction wrenches (36.20 N/cm; SE, 0.08 N/cm) and used spring wrenches (36.45 N/cm; SE, 0.08 N/cm). Discrepancies in torque could impact the clinical success of screw-retained dental implants. It is recommended that torque wrenches be checked regularly to ensure that they are performing to target values.

Cystic lesions of transient nature viz. Epstein pearls, Bohn's nodules and dental lamina cysts are frequently found in the oral cavities of newborn infants. These cysts arise from the developing dental tissues or from their remnants. These cystic lesions are not commonly seen by the dental surgeons due to their self-limiting nature and ignorance of the parents to seek the professional opinion. However, when contacted by anxious parents seeking treatment, dental surgeons should be able to explain and reassure the parents about the transient nature of these lesions and need for no treatment but regular follow-up. The present case report was written with the purpose to increase the awareness in dental surgeons about the peculiar clinical presentation and self-limiting nature of these cystic lesions, so that unnecessary surgical intervention can be avoided in such young infants.

Image post-processing of dental digital radiographs, a function which used commonly in dental practice is presented in this article. Digital radiography has been available in dentistry for more than 25 years and its use by dental practitioners is steadily increasing. Digital acquisition of radiographs enables computer-based image post-processing to enhance image quality and increase the accuracy of interpretation. Image post-processing applications can easily be practiced in dental office by a computer and image processing programs. In this article, image post-processing operations such as image restoration, image enhancement, image analysis, image synthesis, and image compression, and their diagnostic efficacy is described. In addition this article provides general dental practitioners with a broad overview of the benefits of the different image post-processing operations to help them understand the role of that the technology can play in their practices.

To determine the prevalence amng current U.S. Army recruits of dental conditions requiring treatment, an assessment was done of the dental care needs of a 3 percent sample (N = 5,613) of incoming recruits at all seven U.S. Army reception stations that operate under a dental treatment planning concept. Both the treatment needs of the total sample and of each Army component--that is, Regular, Reserve, and National Guard forces--were quantified. The results indicated that the requirement for dental care among Army recruits currently being processed for training is approximately the same as it was for such recruits at the time that the Selective Service System draft was in effect, although the types of care needed have changed. Like the draft-based recruits, current Army recruits enter active-duty status with a substantial backlog of unmet dental care needs. PMID:6867262

Sintered ceramics and glass-ceramics are widely used as biomaterials for dental restoration, especially as dental inlays, onlays, veneers, crowns or bridges. Biomaterials were developed either to veneer metal frameworks or to produce metal-free dental restorations. Different types of glass-ceramics and ceramics are available and necessary today to fulfill customers' needs (patients, dentists and dental technicians) regarding the properties of the biomaterials and the processing of the products. All of these different types of biomaterials already cover the entire range of indications of dental restorations. Today, patients are increasingly interested in metal-free restoration. Glass-ceramics are particularly suitable for fabricating inlays, crowns and small bridges, as these materials achieve very strong, esthetic results. High-strength ceramics are preferred in situations where the material is exposed to high masticatory forces.

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

Dental pulp stem cells were plated on two dentally relevant materials i.e. PMMA commonly used for denture and Titanium used for implants. In both cases, we probed for the role of surface interaction and substrate morphology. Different films of PMMA were spun cast directly onto Si wafers; PMMA fibers of different diameters were electro spun onto some of these substrates. Titanium metal was evaporated onto Si surfaces using an electron beam evaporator. In addition, on some surfaces, P4VP nanofibers were spun cast. DPSC were grown in alpha-MEM supplemented with 10% fetal bovine serum, 0.2mM L-ascorbic acid 2-phosphate, 2mm glutamine and 10mM beta-glycerol phosphate either with or without 10nM dexamethasone. After 21 days samples were examined using confocal microscopy of cells and by scanning electron microscopy (SEM) and Energy dispersive X-ray Analysis (EDAX). In the case of Titanium biomineralization was observed independent of dexamethasone, where the deposits were templated along the fibers. Minimal biomineralization was observed on flat Titanium and PMMA samples. Markers of osteogenesis and specific signaling pathways are being evaluated by RT-PCR, which are up regulated on each surface, to understand the fundamental manner in which surfaces interact with cell differentiation.

Silver has been used in medicine for centuries because of its antimicrobial properties. More recently, silver nanoparticles have been synthesized and incorporated into several biomaterials, since their small size provides great antimicrobial effect, at low filler level. Hence, these nanoparticles have been applied in dentistry, in order to prevent or reduce biofilm formation over dental materials surfaces. This review aims to discuss the current progress in this field, highlighting aspects regarding silver nanoparticles incorporation, such as antimicrobial potential, mechanical properties, cytotoxicity, and long-term effectiveness. We also emphasize the need for more studies to determine the optimal concentration of silver nanoparticle and its release over time. PMID:25667594

The Selenka orangutan collection obtained from 1892 to 1896 from wild-shot specimens in West Borneo, provides an excellent opportunity to examine dental pathology in free-ranging primates. Two hundred and twenty-three skulls from this collection were analyzed for dental conditions, including carious lesions, local infections (infra-alveolar and periapical osseous defects), horizontal bone loss, and premortem tooth loss. Specimens were sexed, divided into three broad age groups, and compared to ascertain sex-related or age-related differences in occurrence of dental pathology. None of the subadults displays any evidence of dental disease. One individual (2%) in the young adult group has a periapical osseous defect and evidence of horizontal bone loss, and another (2%) has two adjacent interproximal carious lesions. The old adults have a much higher prevalence of individuals afflicted with dental pathologies, including 6% carious lesions, 26% local infections, 23% horizontal bone loss, and 3% premortem tooth loss. The differences between the young and old adults in number of individuals afflicted with dental pathologies is statistically significant for local infections and horizontal bone loss. When compared by sex, the old adult group reveals that females have a higher occurrence of dental pathologies than males in all types of lesions recorded and these differences are statistically significant for local infections and horizontal bone loss. Considering the importance diet plays in the development of dental disease, it is suggested that ecological separation of the sexes, with the subsequent dietary differences, could be an important factor determining the higher prevalence of dental lesions observed in female orangutans. Additionally, the importance of local ecological factors, which may affect dietary patterns, are recognized as a potential source of variation in dental pathologies among different samples of orangutans.

The purpose of this study was to identify and compare the perspectives of dental students towards their career choice and dental education in Japan and Sweden. One hundred and fourteen dental students from the Nippon Dental University, Japan and 43 dental students from the Karolinska Institutet, Sweden participated in this study. Information was derived from a self-answered questionnaire consisting of five items for career choice and six items for dental education. Chi-square test and Wilcoxon signed-rank test were used for comparison. Significant differences were detected for 10 questionnaire items between the two countries. Regarding motivation towards the career choice, 44% of Swedish students indicated interpersonal motives related to helping other people, whereas 32% of Japanese students indicated expectations of their family in the dental profession. As future career options, 64% of Japanese and 47% of Swedish students planned to work as general dentists. More Swedish students (37%) preferred specialisation than Japanese students (17%). Nearly three-quarters of the Swedish students were satisfied with the teaching faculty of their school, whilst only 32% of the Japanese students indicated content. The perspectives of dental students were different in Japan and Sweden. This study provides a description of the perspectives of Japanese and Swedish dental students and enables better understanding of career decision and dental curriculum issues.

Dental and dental hygiene faculty members often do not provide consistent instruction in the clinical environment, especially in tasks requiring clinical judgment. From previous efforts to calibrate faculty members in calculus detection using typodonts, researchers have suggested using human subjects and emerging technology to improve consistency in clinical instruction. The purpose of this pilot study was to determine if a dental endoscopy-assisted training program would improve intra- and interrater reliability of dental hygiene faculty members in calculus detection. Training included an ODU 11/12 explorer, typodonts, and dental endoscopy. A convenience sample of six participants was recruited from the dental hygiene faculty at a California community college, and a two-group randomized experimental design was utilized. Intra- and interrater reliability was measured before and after calibration training. Pretest and posttest Kappa averages of all participants were compared using repeated measures (split-plot) ANOVA to determine the effectiveness of the calibration training on intra- and interrater reliability. The results showed that both kinds of reliability significantly improved for all participants and the training group improved significantly in interrater reliability from pretest to posttest. Calibration training was beneficial to these dental hygiene faculty members, especially those beginning with less than full agreement. This study suggests that calculus detection calibration training utilizing dental endoscopy can effectively improve interrater reliability of dental and dental hygiene clinical educators. Future studies should include human subjects, involve more participants at multiple locations, and determine whether improved rater reliability can be sustained over time.

This article explained the character of dental disease and effective facts for dental health utilization, and current situation of basic medical insurance for oral diseases through checking up relative articles. Dental insurance had a positive effect on utilization of dental medical service and public oral health. The PEST tool was used to analyze the environment of dental insurance developing direction and feasibility in this article, and then raise some suggestions and core strategies for developing dental insurance. We believe that the dental insurance can increase the oral health service utilizations and enhance the oral health for Chinese people. Only oral insurance will be developed, Chinese oral health could be geared to international practice.

Background: Titanium has been the most popular material of choice for dental implantology over the past few decades. Its properties have been found to be most suitable for the success of implant treatment. But recently, zirconia is slowly emerging as one of the materials which might replace the gold standard of dental implant, i.e., titanium. Materials and Methods: Literature was searched to retrieve information about zirconia dental implant and studies were critically analyzed. PubMed database was searched for information about zirconia dental implant regarding mechanical properties, osseointegration, surface roughness, biocompatibility, and soft tissue health around it. The literature search was limited to English language articles published from 1975 to 2015. Results: A total of 45 papers met the inclusion criteria for this review, among the relevant search in the database. Conclusion: Literature search showed that some of the properties of zirconia seem to be suitable for making it an ideal dental implant, such as biocompatibility, osseointegration, favourable soft tissue response and aesthetics due to light transmission and its color. At the same time, some studies also point out its drawbacks. It was also found that most of the studies on zirconia dental implants are short-term studies and there is a need for more long-term clinical trials to prove that zirconia is worth enough to replace titanium as a biomaterial in dental implantology.

Dental caries, trauma, and other possible factors could lead to injury of the dental pulp. Dental infection could result in immune and inflammatory responses mediated by molecular and cellular events and tissue breakdown. The inflammatory response of dental pulp could be regulated by genetic and epigenetic events. Epigenetic modifications play a fundamental role in gene expression. The epigenetic events might play critical roles in the inflammatory process of dental pulp injury. Major epigenetic events include methylation and acetylation of histones and regulatory factors, DNA methylation, and small non-coding RNAs. Infections and other environmental factors have profound effects on epigenetic modifications and trigger diseases. Despite growing evidences of literatures addressing the role of epigenetics in the field of medicine and biology, very little is known about the epigenetic pathways involved in dental pulp inflammation. This review summarized the current knowledge about epigenetic mechanisms during dental pulp inflammation. Progress in studies of epigenetic alterations during inflammatory response would provide opportunities for the development of efficient medications of epigenetic therapy for pulpitis. PMID:26901577

Due, in part, to the unique structure of the tooth, dental pain is initiated via distinct mechanisms. Here we review recent advances in our understanding of inflammatory tooth pain and discuss 3 hypotheses proposed to explain dentinal hypersensitivity: The first hypothesis, supported by functional expression of temperature-sensitive transient receptor potential channels, emphasizes the direct transduction of noxious temperatures by dental primary afferent neurons. The second hypothesis, known as hydrodynamic theory, attributes dental pain to fluid movement within dentinal tubules, and we discuss several candidate cellular mechanical transducers for the detection of fluid movement. The third hypothesis focuses on the potential sensory function of odontoblasts in the detection of thermal or mechanical stimuli, and we discuss the accumulating evidence that supports their excitability. We also briefly update on a novel strategy for local nociceptive anesthesia via nociceptive transducer molecules in dental primary afferents with the potential to specifically silence pain fibers during dental treatment. Further understanding of the molecular mechanisms of dental pain would greatly enhance the development of therapeutics that target dental pain.

Dental hygiene, as an emerging profession, needs to increase the number of intervention studies that identify improvements in oral health outcomes for clients. Historically, dental hygiene studies have typically been atheoretical, but the use of theoretical frameworks to guide these studies will increase their meaningfulness. Rogers' theory of diffusion of innovations has been used to study research utilization across many disciplines, and may offer insights to the study of research use in dental hygiene. Research use is an important component of evidence-based practice (EBP), and diffusion of research knowledge is an important process in implementing EBP. The purpose of this paper is to use diffusion of innovations theory to examine knowledge movement in dental hygiene, specifically through the example of the preventive practice of oral cancer screening by dental hygienists, considered as an innovation. Diffusion is considered to be the process by which an innovation moves through communication channels over time among a social network. We suggest diffusion theory holds promise for the study of knowledge movement in dental hygiene, but there are limitations including access to and understanding research studies as innovations. Nevertheless, using a theoretical framework such as Rogers' diffusion of innovations will strengthen the quality of intervention research in dental hygiene, and subsequently, health outcomes for clients.

Aims: The aim of the study was to assess the awareness of the patients regarding implant-retained prosthesis as an option for tooth replacement and the knowledge about tooth replacement as a whole including source of information and attitude towards it amongst Malaysian population. Materials and Methods: Information on demographic characteristics, knowledge about implant as an option for missing tooth replacement, source of information and knowledge about other options of tooth replacement were obtained from patients visiting various dental outpatient departments of hospital and private dental clinics using nationwide self-explanatory survey. Results: Amongst the 1013 response retrieved, 27% of respondents felt moderately well informed about the dental implant treatment. Only 9% of the respondents had dental implant treatment before and 17% felt well informed about different alternatives of replacing missing teeth. The dentists were the main source of information regarding dental implant treatment modality followed by friends and electronic media. 55.6% respondents felt implant to be as good as own teeth during function whereas high cost was the major limiting factor for implant treatment. Conclusion: 56% of Malaysian population was aware of dental implant as an alternative for replacing missing teeth. Necessary efforts and measures should be made to raise the awareness of dental implant treatment in the country. PMID:26752875

In spite of using recommended firing and displayed temperatures, low-fired dental porcelain more often demonstrates unsatisfactory results after firing than porcelain fired at higher temperatures. It could therefore be anticipated that temperatures shown on the display are incorrect, implying that the furnace does not render correct firing programs for low-fired porcelain. The purpose of this study is to investigate deviations from the real temperature during the firing process and also to illustrate the service and maintenance discipline of furnaces at dental laboratories. Totally 20 units of four different types of dental furnaces were selected for testing of temperature accuracy with usage of a digital temperature measurement apparatus, Therma 1. In addition,the staffs at 68 dental laboratories in Sweden were contacted for a telephone interview on furnace brand and on service and maintenance program performed at their laboratories. None of the 20 different dental furnaces in the study could generate the firing temperatures shown on the display, indicating that the hypothesis was correct. Multimat MCII had the least deviation of temperature compared with displayfigures. 62 out of 68 invited dental laboratories chose to participate in the interviews and the result was that very few laboratories had a service and maintenance program living up to quality standards. There is room for improving the precision of dental porcelain furnaces as there are deviations between displayed and read temperatures during the different steps of the firing process.

This was an observational study in which the management policies and procedures associated with infection control and instrument decontamination were examined in 179 dental surgeries by a team of trained surveyors. Information relating to the management of a wide range of infection control procedures, in particular the decontamination of dental instruments, was collected by interview and by examination of practice documentation. This study found that although the majority of surgeries (70%) claimed to have a management policy on infection control, only 50% of these were documented. For infection control policies, 79% of surgeries had access to the British Dental Association Advice Sheet A12. Infection control policies were claimed to be present in 89% of surgeries, of which 62% were documented. Seventy-seven per cent of staff claimed to have received specific infection control training, but for instrument decontamination this was provided mainly by demonstration (97%) or observed practice (88%). Many dental nurses (74%) and dental practitioners (57%) did not recognise the symbol used to designate a single-use device. Audit of infection control or decontamination activities was undertaken in 11% of surgeries. The majority of surgeries have policies and procedures for the management of infection control in dental practice, but in many instances these are not documented. The training of staff in infection control and its documentation is poorly managed and consideration should be given to development of quality management systems for use in dental practice.

Psychophysiological responses indicating the preparation of defensive behaviour, such as heart rate (HR)-increase and startle-response (SR) potentiation, have often been reported amongst individuals suffering from phobic disorders when exposed to phobia-related information. Although exposure is widely considered the 'gold standard' for treatment of Specific Phobia, it is unclear to what extent psychophysiological defensive response patterns change following treatment, and whether any changes are maintained. We assessed the acoustic SR- and HR-response to neutral, positive, negative and phobia-related pictures and sounds in 41 individuals currently suffering from dental phobia, 22 formerly dental phobic individuals who had remitted following an exposure-based treatment eight months prior to assessment, and 29 control individuals with no history of dental phobia. We observed SR-potentiation to dental-related stimuli in controls combined with HR-deceleration. In contrast, amongst phobic individuals SR-potentiation was accompanied by HR-acceleration to dental pictures. Successfully treated individuals showed inhibited startle reactivity in combination with HR-deceleration to dental related materials of both modalities. Our findings suggest inappropriate fight-flight preparation amongst individuals with dental phobia, reflecting overactivation of the defensive system. However, successful treatment results in inhibited physiological defence preparation, with remitted individuals displaying a response pattern that differed from that of phobic individuals and controls.

Access to care continues to be an overriding issue in dentistry. The development of new categories of dental auxiliaries, such as mid-level providers, is a matter of concern to many states and the dental profession. Tennessee has an EFDA educational program for dental auxiliaries taught by dental school educators who have trained more than 300 auxiliary personnel in restorative and prosthetic dentistry. Graduates of this educational program have helped keep Tennessee's dentists well ahead of any increased demand for dental care.

As health care practitioners, dental hygienists need information-gathering skills and the confidence to both perform literature searches in Internet databases and assess the results in order to utilize the wealth of scientific literature that supports evidence-based practice. The aim of this study was to assess the information-seeking strategies of dental hygienists. A self-administered electronic survey of thirty-eight questions was sent to 5,007 licensed dental hygienists in District III of the American Dental Hygienists' Association. The overall response rate was 7.9 percent (396/5,007). Most (90.9 percent) of the respondents were currently practicing dental hygiene, with 62.9 percent having practiced more than ten years. Approximately 56 percent had graduated from a two-year dental hygiene program and had graduated before 1998. Nearly all of the respondents who graduated in 1999 or after were confident using a computer (96.2 percent) and the Internet (95.4 percent); lower percentages of the pre-1999 graduates expressed such confidence (68.6 percent using a computer and 80.7 percent using the Internet). Most respondents (90.9 percent) who graduated in 1999 or after reported receiving evidence-based decision making (EBDM) training in their dental hygiene program- an increase over the 51.8 percent of pre-1999 graduates who reported having received it-though lower percentages (78.2 and 48.0 percent, respectively) reported thinking their EBDM training was adequate. Though the response rate was low, these results may suggest that information-gathering skills are being more effectively addressed in recent dental hygiene education than previously. Continuing education courses that teach hands-on navigation of databases and methods to search the scientific literature and analytically appraise it could increase both the skills and comfort level of dental hygienists, especially those who graduated more than a decade ago.

Epidemiological and intervention studies have suggested that infections are risk factors for coronary heart disease (CHD). Dental infections have appeared as cardiovascular risk factors in cross-sectional and in follow-up studies, and the association has been independent of the "classic" coronary risk factors. This case-control study aimed at detailed assessment of the dental pathology found in various CHD categories (including elderly patients). Altogether, 85 patients with proven coronary heart disease and 53 random controls, matched for sex, age, geographic area, and socio-economic status, were compared with regard to dental status, assessed blindly with four separate scores, and to the "classic" coronary risk factors (seven of the controls had CHD, and they were not included in the analyses). The dental indices were higher among CHD patients than in the controls, but, contrary to previous studies, the differences were not significant (between the CHD patients and their matched controls or among the different CHD categories). This result could not be explained by potential confounding factors. The participants in the present study were older and had more often undergone recent dental treatment in comparison with subjects in our earlier studies. Age correlated with the severity of dental infections only in the random controls but not in the coronary patients who, although young, already had high dental scores. We believe that the higher age of the participants in the present study is the most likely reason for the results. Other possible explanations include an age-related selection bias among older CHD patients, and the fact that those participating in studies like this may have better general health and thus also less severe dental infections. Thus, the role of dental infections as a coronary risk factor varies according to the characteristics of the population studied.

The purpose of this paper is to present the current activities of a research collaborative program between three institutions from Zagreb (School of Dental Medicine, Institute of Physics, and Institute Ruđer Bo\\vsković). Within the scope of this program, it is planned to investigate and find guidelines for the refinement of the properties of dental biomaterials (DBs) and of procedures in restorative dental medicine. It is also planned to identify and model the dominant mechanisms which control polymerization of DBs. The materials to be investigated include methacrylate based composite resins, new composite materials with amorphous calcium phosphate, silorane based composite resins, glass-ionomer cements, and giomer.

Urinary metabolites before dental treatment were compared in a group of patients with dental phobia and in a matched control group. Plasma adrenaline, noradrenaline, and free fatty acids were estimated before treatment, immediately after sedation with diazapam 0.2 mg/kg body weight in the phobic patients, during induction of oral anaesthesia, and during and after surgery. Patients with dental phobia had significantly higher levels of adrenaline, which were only temporarily lowered by sedation, and which during treatment remained consistently higher than those of control patients.

A large number of materials used in the diagnosis, treatment and prevention of dental, periodontal and oral mucosal diseases may induce acute or chronic reactions in the oral cavity including allergic reactions. Clinically, it may be difficult to discriminate oral mucosal changes caused by dental materials from changes related to oral mucosal diseases. Diagnosis and management of allergic reactions in the oral mucosa may therefore be a major challenge. The purpose of this paper is to draw attention to commonly used dental materials, which can trigger typical, but also atypical, symptoms and clinical signs of an allergic reaction.

This article highlights the commonly used medications used in dentistry and oral surgery. General dentists and specialists must be knowledgeable about the pharmacology of the drugs currently available along with their risks and benefits. Enteral sedation is a useful adjunct for the treatment of anxious adult and pediatric patients. When enteral sedation is used within the standards of care, the interests of the public and the dental profession are served through a cost-effective, effective service that can be widely available. Oral sedation enables dentists to provide dental care to millions of individuals who otherwise would have unmet dental needs.

A hand-held, fiber optic based dental device with optical coherence domain reflectometry (OCDR) sensing capabilities provides a profile of optical scattering as a function of depth in the tissue at the point where the tip of the dental explorer touches the tissue. This system provides information on the internal structure of the dental tissue, which is then used to detect caries and periodontal disease. A series of profiles of optical scattering or tissue microstructure are generated by moving the explorer across the tooth or other tissue. The profiles are combined to form a cross-sectional, or optical coherence tomography (OCT), image.

Current research shows that women tend to receive less dental care than usual when they are pregnant. In 2012, the first national consensus statement on oral health care during pregnancy was issued, emphasizing both the importance and safety of routine dental care for pregnant women. This article reviews the current recommendations for perinatal oral health care and common oral manifestations during pregnancy. Periodontal disease and its association with preterm birth and low birth weight are also discussed, as is the role played by dental intervention in these adverse outcomes.

Referral of periodontal patients requires development of a complex set of decision making skills. This study was conducted to determine criteria used by dental and dental hygiene students regarding the referral of periodontal patients for specialty care. Using mixed methods, a thirteen-item survey was developed to elicit the students' perceptions of their knowledge, confidence regarding managing patients, and clinical reasoning related to periodontal patients. The instrument was administered during the summer prior to (T1) and at the end of the students' final year (T2) of training. Seventy-nine dental students (81 percent of total class) and thirty dental hygiene students (83 percent of total class) completed T1. At T2, forty-two dental (44 percent of total class) and twenty-six dental hygiene students (87 percent of total class) completed the questionnaire. While 90 percent of dental and 96 percent of dental hygiene respondents reported a willingness to refer patients with active disease to specialists, only 40 percent of dental and 36 percent of dental hygiene respondents reported confidence in diagnosing, treating, and appropriately referring such patients. The students' ability to recognize critical disease and risk factors influencing referral was good; however, clinical application of that knowledge indicated a gap between knowledge and applied reasoning. The students' attitudes about the importance of periodontal disease and their perceived competence to identify critical disease risk factors were not significantly related (p>0.05) to correct clinical decisions in the case scenarios. The study concludes that dental and dental hygiene curricula should emphasize both the acquisition and application of knowledge regarding criteria for referral of periodontal patients.

Oral Health in America: A Report of the Surgeon General, and the subsequent National Call to Action to Promote Oral Health contributed significantly to raising the awareness of the American public and the dental profession regarding the lack of access to oral health care by many Americans, especially minorities and low income populations, with resulting disparities in oral health. The problem is particularly acute among children. The current workforce of dentists in the United States is inadequate to meet the oral health care needs of children in terms of numbers of dentists, as well as their distribution, ethnicity, education, and practice orientation. Dental hygienists trained in an expanded scope of practice, can help address the workforce inadequacy. Dental therapists, educated in 2-year programs of postsecondary education, comparable to America's associate degree dental hygiene programs, have been used throughout the world to provide basic, primary oral health care for children. Research has documented that utilizing dental therapists is a cost effective method of improving access to care for children. Countries that have led the way in introducing dental therapists to care for their children are now integrating their separate 2-year curriculum in dental therapy and dental hygiene into a 3-year curriculum to prepare a clinician dually trained in both dental therapy and dental hygiene. This clinician is being designated an oral health therapist. Expanding the education of dental hygienists in the United States to include skills of the internationally acclaimed dental therapist can produce oral health therapists, individuals capable of addressing the basic preventive, restorative, and minor surgical needs of children, but also able to continue to address the preventive and periodontal needs of adults.

The aim of this study was to assess the clinical and socioeconomic indicators associated with dental anxiety in preschool children with severe dental caries. A total of 100 children between 3 and 5 years of age were selected during a dental screening procedure. The selection criteria were having at least one tooth with dental caries and a visible pulpal involvement, ulceration, fistula, and abscess (PUFA) index of ≥1 in primary teeth. Before the clinical examination or any treatment procedure was performed, we evaluated the children's dental anxiety using the Facial Image Scale (FIS). Parents completed a questionnaire on socioeconomic conditions, which included the family structure, number of siblings, parental level of education, and family income. A dentist blinded to FIS and socioeconomic data performed the clinical examination. Poisson regressions associate clinical and socioeconomic conditions with the outcome. Most of the children (53%) experienced extensive dental caries (dmf-t ≥ 6), and all children had severe caries lesions, with a PUFA index of ≥1 in 41% and that of ≥2 in 59%. The multivariate adjusted model showed that older children (4-5-year old) experienced lower dental anxiety levels compared with younger children (3-year old) (RR = 0.35; 95%CI: 0.17-0.72 and RR = 0.18; 95%CI: 0.04-0.76, respectively), and children with three or more siblings were associated with higher levels of dental anxiety (RR = 2.27; 95%CI: 1.06-4.87). Older age is associated with low dental anxiety, and more number of siblings is associated with high dental anxiety in preschool children, whereas the severity or extent of dental caries is not associated with dental anxiety.

In cases of identification of bones, skeletal segments or isolated bones, searching for biotypologic diagnostic data to estimate an individual's age enables comparing these data with those of missing individuals. Enamel, dentin and pulp undergo remarkable changes during an individual's life. The enamel becomes more mineralized, smoother and thinner, and deteriorates because of physiological and pathological factors. Dental pulp decreases in volume due to the deposition of secondary dentin; thus, the dentin becomes thicker with time. In natural teeth, the fluorescence phenomenon occurs in dentin and enamel and changes in those tissues may alter the expression of the natural tooth color. The aim of this study was to assess the correlation between age and teeth fluorescence for individuals from different age groups. The sample consisted of 66 randomly selected Brazilians of both genders aged 7-63 years old. They were divided into 6 groups: Group 1 - aged 7-12 years, Group 2 - aged 13-20 years, Group 3 - aged 21-30 years, Group 4 - aged 31-40 years, Group 5 - aged 41-50 years and Group 6 - aged between 51 and 63 years. Upper right or left central incisors were used for the study. Restored and aesthetic rehabilitated teeth were excluded from the sample. The measurement of tooth fluorescence was carried out via computer analysis of digital images using the software ScanWhite DMC/Darwin Systems - Brazil. It was observed that dental fluorescence decreases when comparing the age groups 21-30, 31-40, 41-50 and 51-63 years. The results also showed that there is a statistically significant difference between the groups 41-50 years and 21-30 years (p=0.005) and also among the group 51-63 years and all other groups (p<0.005). It can be concluded that dental fluorescence is correlated with age and has a similar and stable behavior from 7 to 20 years of age. It reaches its maximum expected value at the age of 26.5 years and thereafter decreases.
Dental pain is the most common symptom associated with a wide array of dental problems and significantly impacts the oral health-related quality of life. The epidemiology and prevalence of oral diseases that could lead to dental pain are diverse and indicate regional variations. Several researchers have dwelled into the neurobiology and pathophysiology of dental pain making the pain pathways more clear and deciphering the precise targets for the management of pain. Although a number of pharmacological drugs are available in the market, a significant percentage of the population in India prefers alternative herbal medication for relief from dental pain due to the side effects and interactions of pharmacological treatment. However, there is a void in dental literature pertaining to the use, benefits, and safety of the herbal medicines. Therefore, the present assessment has been penned down, focusing on the current multimodal approaches for treating dental pain, the current unmet need, and the role of herbal medication in India for the management of dental pain, with a discussion on novel herbal dental gel.

This ross-sectional study involving 127 male prisoners evaluates the use of dental services and dental caries among Brazilian inmates. Data were collected by interview and clinical examination. Sociodemographic and sentencing information as well as use of dental services, self-reported dental morbidity, self-perception, and oral health impacts were investigated. The mean DMFT index value was 19.72. Of the components, the decayed component showed the highest mean value (11.06 ± 5.37). Statistically significant association was found between DMFTs with values from 22 to 32 and oral health satisfaction (p = 0.002), difficulty speaking (p = 0.024), shame of talking (p = 0.004) and smiling (p < 0.001). Regarding the use of dental services, 80% had their last dental appointment less than one year ago, with most visits occurring in prison (80%), with restorative treatment (32%), followed by dental pain (26.4%), being the main reasons for such appointments. Most prisoners used dental services provided by the prison. Although restorative treatment has been the main reason for the use of dental services, “decayed” and “missing” components contributed to the high mean DMFT index. PMID:25429680

Early detection of childhood caries is important to childrens' overall health. Untreated childhood caries can lead to pain, as in abscesses from prolonged neglect; altered dietary intake; and delays in the development of the permanent teeth if the primary teeth are prematurely lost. In the summer of 2000, funds were provided to various oral health care provider organizations by the Illinois Department of Public Health, Division of Oral Health, to purchase portable equipment to deliver preventive services (i.e., exams, sealants, and oral hygiene education) to second-grade and sixth-grade children who qualified for Medicaid and/or free and reduced-cost lunch programs. The Dental Sealant Grant Program at Southern Illinois University in Carbondale was a unique program that utilized dental hygiene students as the primary human resource. Within the state, the Dental Sealant Grant Program was, at the time of this report, the only grantee sponsored by a stand-alone dental hygiene program (not affiliated with a dental school). Other positive aspects of the dental hygiene-sponsored sealant program were that the supervising dentist was the primary Medicaid provider and a member of the dental hygiene faculty; dental hygiene faculty participated actively as site coordinators and clinicians; and dental hygiene students were given the opportunity to volunteer for the program as a service-learning option.

Increasing the quality of the services provided in a Dental School can raise the satisfaction level of patients and consequently increase the level of their oral health. This study was conducted to evaluate the quality of dental care and services provided to patients referred to a Dental School in Kerman, Iran. In this qualitative study, face-to-face, in-depth interviews were conducted with 41 participants [25 patients (P), 5 nurses (N), 6 dental academic staff (AS), and 5 dental students (S)]. Then, the interviews were transcribed and analyzed, using content analysis of data. Data analysis in qualitative research involves breaking down the data and searching for codes and categories that are then reassembled to form themes. Both positive and negative themes emerged. Positive themes included: good infection control, service accessibility, patient appointments and visits were not assigned on merit, precise examinations, and comprehensive treatment plans. Negative themes included: long wait time, lack of options to pass waiting time, such as newspapers and television, an insufficient number of nurses, and not enough professors for supervision. In addition, the results of this study show that the patients and dental staff have high expectations in relation to dental services, and that implementation of these expectations would increase the overall satisfaction with and the quality of the level of services. Finally, some recommendations for improving services in the Kerman Dental School were given to the managing team of the Dental School.

Aim: To study the awareness, attitude, practice and facilities among the different categories of dental laboratories in Abha city. Materials and Methods: A total of 80 dental technicians were surveyed in the study. The dental laboratories included in the study were teaching institute (Group I), Government Hospital (Group II), Private Dental Clinic (Group III) and Independent laboratory (Group IV). The pre-tested anonymous questionnaire was used to understand knowledge, attitude, facilities, practice and orientation regarding biomedical waste management. Results: The knowledge of biomedical waste categories, colour coding and segregation was better among Group I (55-65%) and Group II (65-75%). The lowest standard of waste disposal was practiced at Group IV (15-20%) and Group III (25-35%). The availability of disposal facilities was poor at Group IV. The continuous education on biomedical waste management lacked in all the Groups. Conclusion: The significant improvement in disposal facilities was required at Group III and Group IV laboratories. All dental technicians were in need of regular training of biomedical waste management. Clinical Significance: The dental laboratories are an integral part of dental practice. The dental laboratories are actively involved in the generation, handling and disposal of biomedical waste. Hence, it is important to assess the biomedical waste management knowledge, attitude, facilities and practice among different categories of dental laboratories. PMID:26962373

The objectives of the study were: 1) to describe the choice of dental care system among 16-year-olds, 2) to describe the utilization of dental services among 16-17-year-olds enrolled in either public or private dental care systems, and to compare the dental services provided by the alternative systems. The study comprised 1,245 adolescents from 3 municipalities; the historical cohort study design was applied; and data were collected from dental records (public dental service) and dental claims (private practice). At age 16, 12% preferred being enrolled in the private practice system, while 88% remained in the public dental care system. During the 2-year study period the attendance rate was 99% for the public system, while 90% attended the private practice system (P< 0.001). Preventive dental services were provided more frequently by the public than the private system (P< 0.001). Despite the fact that the economic barrier was eliminated a lower attendance rate was observed for patients transferred to the private practice system.

There are several types of lasers that will allow pediatric dentists to remove soft tissue (such as diode or Neodynium:Yttrium-Aluminum-Garnet (Nd:YAG) lasers) or remove both hard and soft tissue (such as the Erbium:YAG laser), in addition to photobiostimulation or therapeutic lasers that produce their healing benefits without producing heat. Lasers allow pediatric dentists to provide optimal care without many of the fear factors that result from conventional dental techniques. Lasers are extremely safe and effective when the user has a proper understanding of laser physics. Using lasers for caries removal, bone removal, and soft tissue treatment can reduce postoperative discomfort and infection and make it possible for dentists to provide safe, simple treatments.

Dental pulp testing is a useful and essential diagnostic aid in endodontics. Pulp sensibility tests include thermal and electric tests, which extrapolate pulp health from sensory response. Whilst pulp sensibility tests are the most commonly used in clinical practice, they are not without limitations and shortcomings. Pulp vitality tests attempt to examine the presence of pulp blood flow, as this is viewed as a better measure of true health than sensibility. Laser Doppler flowmetry and pulse oximetry are examples of vitality tests. Whilst the prospect is promising, there are still many practical issues that need to be addressed before vitality tests can replace sensibility tests as the standard clinical pulp diagnostic test. With all pulp tests, the results need to be carefully interpreted and closely scrutinised as false results can lead to misdiagnosis which can then lead to incorrect, inappropriate, or unnecessary treatment.

Equine congenital dental deformities are not limited merely to those presented here; however, the examples discussed offer the reader an appreciation for the range of severity and complexity that may be found in affected horses. The veterinarian is obligated to provide the best possible care for the patient and to relieve animal suffering. The lack of definitive evidence for heritability of many of these defects can place the veterinarian in an untenable position, particularly when presented with literature that proclaims or suggests without evidence that a particular condition is inherited. In such cases, the veterinarian is encouraged to counsel owners, citing substantiated medical information, and to recommend that owners make the decision to eliminate the affected animals' ability to reproduce.

This paper presents the dental findings of a child with the oculocerebrorenal syndrome of Lowe. The genetic abnormality in this condition results in an inborn error of inositol phosphate metabolism. Renal tubular dysfunction leads to metabolic acidosis and phosphaturia. At 4 years, generalised mobility of all primary teeth was noted. It is postulated that a defective inositol phosphate metabolism was responsible for the periodontal pathology found in this case. This is in direct contrast with previous reports of prolonged retention of primary teeth in children with this condition. Histology of extracted primary incisors demonstrated enlarged pulp chambers and mildly dysplastic dentin formation. This is consistent with a chronic subrachitic state, a known feature of Lowe syndrome, but no prominent interglobular dentin was present.

The purpose of this study was to investigate the effect of ultrasonic scaling on teeth restored with a light-cured resin. Ultrasonic scaling is a very popular periodontal therapy among dentists, and used for the removal of dental plaque and calculus in order to reduce and eliminate inflammation. Given the fact that most ultrasonic devices are used at high frequencies to perform scaling, undesirable consequences, such as loss of adhesion and increase in surface roughness, may occur in teeth that have been restored with light-cured resins. Electrochemical impedance spectroscopy (EIS) and scanning electron microscopy were used to investigate the effects of ultrasonic treatments at the dental material-hard dental tissue interface. After ultrasonic scaling, EIS measurements were performed on a human tooth that had been restored with a light-cured resin filling. The data were analyzed and the influence of ultrasound was shown after visualization of the hard dental tissues and the dental material as equivalent electrical circuits. The study revealed, through EIS measurements, that ultrasonic scaling affected the resistance of the light-cured resin filling and dentin, whereas the enamel was affected only slightly. Scanning electron microscopy revealed an increase in roughness of the dental material.
Through following the FPPD protocol for multiple adjacent implants, and delivering final abutments, picking up the metal framework, and delivering provisionals, many benefits are gained. The benefits of following the FPPD protocol are as follows: The restorative dentist is trying-in and delivering the final abutments in one visit as opposed to removing them and placing them multiple times. This requires less chair time and time for the patient. It also reduces the mechanical stress on the abutment screw and implant body due to the elimination of multiple try-in appointments. When the metal framework is tried-in and verified for fit, the restorative dentist has the opportunity check the retention, check the margins, and make any corrections that might be needed. The abutments will be staying in the mouth when the framework is picked up. This metal try-in allows for a verification of the bite to be given to the dental lab. The delivery of provisionals manufactured by the dental laboratory offers many advantages in the FPPD technique. The patient has a form of tooth much earlier in the traditional appointment sequence. The patient can now offer feedback to the doctor and laboratory for fabrication of the permanent prosthesis with regards to shape and color. The laboratory-fabricated provisionals offer progressive loading to the implants through having a reduced occlusion yet allowing food to stimulate the implants. Overall, the FPPD technique offers shorter appointment times, more rapid delivery of fixed supported teeth, improved doctor-technician communication, and less mechanical wear on the implant parts.

Nutrition and diet can affect teeth in three ways: by affecting the structure of teeth (and thus appearance), by causing dental caries and by eroding teeth. The importance of dietary sugars in causing dental caries is clearly established and a reduction in consumption of non-milk extrinsic sugars recommended by government. The Health Education Authority has played a major role in promoting this aspect of dietary advice. The structure of teeth is influenced by nutrition; much of the evidence for this being published by Mellanby and colleagues in this country. Interest in this topic has increased recently and it seems probable that malnutrition enhances susceptibility to dental caries, and possible that it increases susceptibility to enamel defects especially in areas with moderate to high levels of fluoride ingestion. The prevalence and severity of dental erosion is likely to be increasing in Britain. Preliminary studies indicated that fluoride helps to protect teeth against erosion, but more research is needed.

The use of dental implants for the rehabilitation of missing teeth has broadened the treatment options for patients and clinicians equally. As a result of advances in research in implant design, materials, and techniques, the use of dental implants has increased dramatically in the past two decades and is expected to expand further in the future. Success of dental implants depends largely on the quality and quantity of the available bone in the recipient site. This however may be compromised or unavailable due to tumor, trauma, periodontal disease, etc., which in turn necessitates the need for additional bone manipulation. This review outlines the various bone manipulation techniques that are used to achieve a predictable long-term success of dental implants. PMID:27433052

This paper describes an active learning-based education tool which enables dental students to learn preventive techniques relevant to patient dental health behaviour. 2 studies were conducted involving 33, 2nd year (study 1) and 9, 3rd year (study 2) undergraduate dental students. In study 1, snacking behaviour and its antecedents were analysed from detailed 3-day diet diaries completed by the students. Study 2 entailed the students changing one aspect of their sugar/diet behaviour using self-management techniques. It is concluded that dental students can successfully (a) identify antecedents to sugar snacking behaviours on several levels, i.e., cognitive, emotional and situational, (b) set goals and use behaviour change techniques to modify these behaviours, and (c) appreciate that this experience is relevant to similar preventive techniques that they will use in clinical practice. Training in the application of these skills to their own maladaptive behaviours provides a strong educational tool based on psycho-educational theories.

Cerebral palsy (CP) is a common chronic motor disorder with associated cognitive, communicative, and seizure disorders. Children with CP have a higher risk of dental problems creating significant morbidity that can further affect their wellbeing and negatively impact their quality of life. Screening for dental disease should be part of the initial assessment of any child with CP. The objective of this article is to present an updated overview of dental health issues in children with CP and outline important preventative and practical strategies to the management of this common comorbidity. Providing adequate oral care requires adaptation of special dental skills to help families manage the ongoing health issues that may arise. As oral health is increasingly recognized as a foundation for general wellbeing, caregivers for CP patients should be considered an important component of the oral health team and must become knowledgeable and competent in home oral health practices.

Deaths during dental treatment or as a result of dental treatment are rare, but the unfortunate fact is that such deaths do occur. Unexpected death of a patient can be emotionally draining and even harrowing to his or her relatives. The death of a patient may bring an enormous feeling of anxiety both at the personal and professional level, stress, profound grief, damage to self-esteem, loss of self-confidence, reputation, and specter of litigation on a dental surgeon. No dentist can be guaranteed to be free of such an incident during the course of his or her practice. The dentist should respond in a compassionate and respectful manner in case of such unfortunate tragic events, and also ensure self-protection. This article emphasizes on prevention of such incidents and throws some light on how to respond in case of an unfortunate death in a dental clinic, including the medico-legal aspects. PMID:27555720

In most industrialized countries the issues of unemployment or under-employment are becoming more critical for the members of the dental associations. In some countries this is creating greater competition between the private practitioners and public health dentists as well as between private dental practitioners themselves. Modern marketing, especially service marketing theory and models, can provide dentists and dental associations with tools to improve their position in relation to patients, political decision makers and other public agencies. However, marketing has to be understood correctly as a philosophy providing a means of approaching the establishing, maintaining and enhancing patient or customer relationships and not as a narrowly defined set of tools. As long as marketing is considered to be external campaigns, such as advertising and not much else, it is bound to fail. Other dimensions of marketing, such as interactive marketing and internal marketing, are of much greater importance to dental practitioners.

The popularity of dental bleaching has increased with the introduction of at-home whitening. Currently available whitening methods include those prescribed by a dental professional for use at home, those applied by the professional in the dental office, a combination of the two, or systems available over the counter. This article reviews the effect, efficacy, and safety of bleaching techniques and materials. Most whitening techniques are considered effective and safe when carried out under the supervision of a dental professional. This article also compares the efficacy and safety of some of the most popular bleaching techniques, including at-home whitening with carbamide peroxide, over-the-counter (OTC) systems, and in-office whitening. Some of these whitening techniques are illustrated in this article.

Forensic dentistry has become an integral part of forensic science over the past 100 years that utilizes dental or oro-facial findings to serve the judicial system. This has been due to the dedication of people like Gustafson's, Keiser-Nielson, and Suzuki for this field. They established the essential role which forensic dentistry plays mainly in the identification of human remains. The tooth has been used as weapons and under certain circumstances, may leave information about the identity of the biter. Dental professionals have a major role to play in keeping accurate dental records and providing all necessary information so that legal authorities may recognize mal practice, negligence, fraud or abuse, and identity of unknown individuals. This paper will try to summarize the various roles of dental experts in forensic medicine. PMID:25298709

Although chronic arterial hypertension is the leading cause of intracranial hemorrhage, an abrupt rise in systemic arterial pressure in normotensive people may sometimes induce a hemorrhagic stroke. Dental treatment is rarely associated with such an event. We report here on two middle-aged women, apparently healthy, who suffered from a fatal intracerebral hemorrhage following a dental treatment. On admission, high levels of arterial hypertension were found. It seems that trigeminal manipulation during dental treatment as well as increased serum levels of induced epinephrine mainly by stress and pain, and the small amounts absorbed from the site of local anesthesia might produce abrupt elevation of blood pressure, subsequent increase in cerebral blood flow and severe, even fatal intracerebral hemorrhage. The addition of catecholamines to local anesthetics should be considered. We recommend the use of benzodiazepin as a premedication drug to reduce stress during dental treatment.

The purpose of this study was to determine the factors that influence and contribute to patient exposure in radiologic procedures performed in the offices of 132 staff members within the dental department of a teaching hospital. A questionnaire was prepared in which data were requested on brands of film used, type of x-ray unit used, processing, and use of leaded apron, cervical shield, and film holder. Offices were also visited to evaluate performance of existing dental x-ray equipment. Both the Dental Radiographic Normalizing and Monitoring Device and the Dental Quality Control Test Tool were evaluated. The average exposure was equivalent to the class D film (220 mR), but only 13% of those surveyed used the faster class E film, which would reduce patient exposure in half. The survey indicates that dentists are not using the newer low-exposure class E film in their practices.

Dental features are one of few biometric identifiers that qualify for postmortem identification; therefore, creation of an Automated Dental Identification System (ADIS) with goals and objectives similar to the Automated Fingerprint Identification System (AFIS) has received increased attention. As a part of ADIS, teeth segmentation from dental radiographs films is an essential step in the identification process. In this paper, we introduce a fully automated approach for teeth segmentation with goal to extract at least one tooth from the dental radiograph film. We evaluate our approach based on theoretical and empirical basis, and we compare its performance with the performance of other approaches introduced in the literature. The results show that our approach exhibits the lowest failure rate and the highest optimality among all full automated approaches introduced in the literature.

Dental personnel are exposed to acrylates due to the acrylic resin-based composites and bonding agents used in fillings. It is well known that these compounds can cause contact allergy in dental personnel. However, in the 1990s, reports emerged on asthma also caused by methacrylates. The main volatile acrylates in dentistry are 2-hydroxyethyl methacrylate and methyl methacrylate. The aim of this study was to quantify the exposure to these acrylates in Swedish dental personnel. We studied the exposure to 2-hydroxyethyl methacrylate and methyl methacrylate in five randomly selected public dental clinics and at the Faculty of Odontology at Göteborg University. In total, 21 whole-day and 46 task-specific short-term (1-18 min) measurements were performed. The median 8-hour time-weighted averages were 2.5 microg/m3 (dentists) and 2.9 microg/m3 (dental nurses) for 2-hydroxyethyl methacrylate, and 0.8 microg/m3 (dentists) and 0.3 microg/m3 (dental nurses) for methyl methacrylate. The maximum short-term exposure levels were 79 microg/m3 for 2-hydroxyethyl methacrylate and 15 microg/m3 for methyl methacrylate, similar in dentists and dental nurses. The observed levels are much lower than in complete denture fabrication. We found only one previous study in dentistry and it showed similar results (though it reported short-term measurements only). Irritant effects would not be expected in healthy people at these levels. Nevertheless, occupational respiratory diseases due to methacrylates may occur in dental personnel, and improvements in the handling of these chemicals in dentistry are warranted. This includes better vials for the bonding agents and avoiding evaporation from discarded materials.

A topic seldom considered and even more rarely discussed among the dental components of the health professions is presented. The dentist's preoccupation with hosts of dental treatment problems has left little time for considering the perplexities of aging, critical illness, or dying or dead patient's relatives. Community dentistry has now forced upon our consciousness the fact that perhaps the subject is one which must not be avoided, if we are to fulfill completely our professional obligations to the public.

Appropriate preoperative assessment of dental patients should always include analysis of their medications. Psychiatric illnesses including panic/anxiety disorder, depression, psychoses, and manic disorders are prevalent within our society. An impressive number of drug formulations are prescribed for these disorders, and they introduce concern regarding side effects and possible drug interactions with medications the dentist may deem necessary for dental care. This article will address essential pharmacology of these psychotropic medications.

Orthodontic emergencies occasionally arise and although they can cause discomfort to the patient, they can usually be stabilized by a general dentist and then followed up by the orthodontist. CPD/Clinical Relevance: Patients undergoing orthodontic treatment may initially present to their general dental practitioner with an orthodontic emergency as opposed to their orthodontist. It is therefore important that general dental practitioners are aware of common orthodontic emergencies and their management.

Upgrades to a dental practice can range from a minor facelift to all new construction. Consulting a certified public accountant is important to properly account for all the various assets that go into a new office so the tax benefits from each can be optimized. After all the dust has settled, practitioners will be able to take pride in their new dental facility and enjoy their surroundings for many years to come.
Administrative requirements for radiographs are found in many segments of the United States health care system. This document presents an FDA radiation recommendation on administratively required dental x-ray examinations. In general, such examinations are not requested to further the patient's dental health, but rather as a means of monitoring claims. However, the administrative use of radiographs that have been taken in the normal course of patient care is usually appropriate, as long as the patient's right to privacy is respected.

Aim: This study was conducted to evaluate the clinical reversal of dental fluorosis with various combinations of calcium, vitamin D3, and ascorbic acid, along with changes in levels of certain biochemical parameters concerned with dental fluorosis. The role of fluoride level of drinking water in the etiology of dental fluorosis and the prevalence of dental fluorosis in both dentitions and teeth were also assessed. Materials and Methods: A total number of 50 patients with clinical features of dental fluorosis without trauma and any adverse habits were selected. Of these, in 30 co-operative patients, estimation of water fluoride level and pretreatment and post-treatment serum and urine fluoride levels were done with ion selective electrode method. The selected 30 patients were divided into three groups, that is, group A, group B, and group C, and were given various combinations of medications like calcium with vitamin D3 supplements, ascorbic acid with vitamin D3 supplements, and chlorhexidine mouthwash (placebo) for three months, respectively. These 30 patients were assessed for any change in the clinical grading of dental fluorosis. Results: No change in clinical grading of dental fluorosis was noted. Considerable reduction in serum and urine fluoride levels was noted in both group A and group B patients. Dental fluorosis was noted in permanent teeth more commonly than deciduous teeth, and permanent maxillary central incisors had the highest prevalence rate. Conclusion: This study comprises only 30 patients with three months of follow-up. So, this sample of patients and duration of follow-up period are conclusive to observe changes in biochemical parameters but not sufficient to observe changes in clinical grading. PMID:23633850

Few studies have been published regarding the importance of oral hygiene education for dental students and little is known about the influence of dental education in dental schools on students' attitudes to the subject. The objective of the present research was to examine the changes that occur in the attitudes of Israeli dental students toward their dental health during the course of their professional training. The research was based on a questionnaire developed at The Hiroshima University, Japan (The Hiroshima University Dental Behavioral Inventory, HU-DBI), and provides a quantitative estimate of the students' attitudes to their dental health. Similar studies have been carried out in several countries (Japan, Australia, Indonesia and Finland). This study was performed on students from the two dental schools in Israel, The Maurice and Gabriela Goldschleger School of Dental Medicine, Tel Aviv University and The Faculty of Dental Medicine at Hebrew University, Jerusalem. Students from all six academic years (1st-6th) were requested to complete the questionnaire within two months, from the beginning of the academic year that started in October 1999. While no significant differences could be detected in the students' attitudes with regard to the dental school of their origin, female students (from both schools) showed a significantly better attitude than their male colleagues throughout the years. Results showed a significant improvement in the students' attitudes through the years of their professional training, especially between the 1st year and the clinical years (5th and 6th) of their studies. This can be related to the teaching curricula in the dental schools in Israel that emphasizes clinical issues in the two last years of study. When comparing the results of this study to similar ones that were conducted in other parts of the world, certain differences become apparent. In spite of the gradual improvement in the Israeli students' attitudes during the course

Despite the advancement in highly active antiretroviral therapy and improved health status of HIV-infected individuals, dental problems are still affecting their life and well-beings. We aimed to establish the prevalence of oral and dental complaints among HIV-infected patients, the prevalence of delayed access to dental service, and factors related with delayed access to dental service. A cross-sectional study using self-report questionnaire completed by the HIV-positive subjects was conducted at the largest HIV research clinic in Thailand during 2009-2010. Of all 299 subjects (28.6% males, 71% females, and 0.4% sex change from male to female: ages ranged from 22 to 59 years [mean 36.7±5.53)]), 84.3% reported of having past or present illnesses or problems related to the dental or oral conditions. The most reported problems were dental hypersensitivity (93.3%), bleeding from the gum (92.1%), and having dental caries (65.9%). Two-hundred and forty-two subjects (80.9%) would not disclose their HIV status when seeing a dentist. The most cited reasons of such behavior were their personal right whether to reveal or not, and being afraid of not receiving dental treatment from the dentists or staffs (51.7 and 40.9%, respectively). It is important to note that HIV-subjects admitted to having fear of being discriminated by the dental staffs even if they trusted their dentists as having high morality. In conclusion, our HIV-subjects had good basic knowledge of oral health with regard to HIV infection, experienced common dental problems, and wished to have accesses to HIV-dental specialist services, if possible.

Dental calculus (calcified tartar or plaque) is today widespread on modern human teeth around the world. A combination of soft starchy foods, changing acidity of the oral environment, genetic pre-disposition, and the absence of dental hygiene all lead to the build-up of microorganisms and food debris on the tooth crown, which eventually calcifies through a complex process of mineralisation. Millions of oral microbes are trapped and preserved within this mineralised matrix, including pathogens associated with the oral cavity and airways, masticated food debris, and other types of extraneous particles that enter the mouth. As a result, archaeologists and anthropologists are increasingly using ancient human dental calculus to explore broad aspects of past human diet and health. Most recently, high-throughput DNA sequencing of ancient dental calculus has provided valuable insights into the evolution of the oral microbiome and shed new light on the impacts of some of the major biocultural transitions on human health throughout history and prehistory. Here, we provide a brief historical overview of archaeological dental calculus research, and discuss the current approaches to ancient DNA sampling and sequencing. Novel applications of ancient DNA from dental calculus are discussed, highlighting the considerable scope of this new research field for evolutionary biology and modern medicine.

Handball has developed into a much faster and high-impact sport over the past few years because of rule changes. Fast sports with close body contact are especially prone to orofacial trauma. Handball belongs to a category of sports with medium risk for dental trauma. Even so, there is only little literature on this subject. The aim of this study was to examine the prevalence and the type of injuries, especially the occurrence of orofacial trauma, habits of wearing mouthguards, as well as degree of familiarity with the tooth rescue box. For this purpose, 77.1% (n=542/703) of all top athletes and coaches from the two highest Swiss leagues (National League A and National League B), namely 507 professional players and 35 coaches, were personally interviewed using a standardized questionnaire. 19.7% (n=100/507) of the players experienced dental trauma in their handball careers, with 40.8% (n=51/125) crown fractures being the most frequent by far. In spite of the relatively high risk of lip or dental trauma, only 5.7% (n=29/507) of the players wear mouthguards. The results of this study show that dental trauma is common among Swiss handball players. In spite of the high risk of dental trauma, the mouthguard as prevention is not adequately known, and correct procedure following dental trauma is rarely known at all.
The aim of the present study was to investigate dental fear in women who have been exposed to different kinds of sexual abuse. In a cross-sectional questionnaire study, 99 sexually abused women were divided into three groups: one group who reported having been exposed to sexual touching (ST); one group who reported intercourse (IC); and one group who reported sexual abuse involving oral penetration (OP). The mean score on dental fear assessments was significantly higher for all groups than for Norwegian women in general. Women in the OP group scored significantly higher than women in other groups on dental fear. The majority of the women reported that they had experienced problems in relation to dental treatment situations. About half of the women in the OP group and one-third in the other groups reported that they had never considered that there was a relationship between the abuse and their problems with dental treatment situations. Significantly more women in the OP group reported that they had not been aware of the relationship, possibly because the abuse had been repressed. The majority of the women with extreme dental fear had never informed a dentist that they had been sexually abused.

Routine dental screening surveys of third graders have proven to be a useful tool to monitor the dental health of a community, especially those of highest risk. In 2010 the PEW Charitable Trust (PEW) conducted state-by-state oral hygiene assessments, giving Hawai‘i a poor grade, with routine dental surveys of children one of several criteria not met. The Maui Oral Health Task Force piloted its own survey for the island of Maui to assess the challenges in implementing a dental screening and to gain an understanding as to how obstacles might be addressed. Three issues were identified: technical (sampling methodology, data interpretation, and analysis), administrative (approvals of protocols, consent forms, and confidentiality), and operational (participation rates, dental referrals, and missing data of socio-economic status). These issues were relatively easy to resolve over the course of a few months due to the public's and providers' outcry over the negative findings of the PEW report. Two hundred and eighty-one students were surveyed, which represents 46% of the children whose forms were sent home for parental consent and approval. Of those returning the forms, 77% had parent's consent to participate. Based on our island survey, the estimated sample size and participation rate for the State of Hawai‘i would be comparable to those of other states, which had met the PEW survey criteria. Comparative exploratory analysis between Maui and survey data from other states underscores the value of prevention in averting dental treatment. PMID:27920943

Aims: The aim of this study is to evaluate the self-perceived need for dental care among medical professionals and general public. Setting and Design: (1) To determine the perceived oral health status. (2) To evaluate the results in understanding the perception of oral health. (3) To determine the patients attitude toward dentist. Subjects and Methods: The study was carried out on 537 patients who came for their regular checkup and treatment. Statistical Analysis Used: The statistical analysis of this study was based on Chi-square test evaluation. The study was performed among in 537 participants. The participants included from age group of both <30 and >30. The study was made in the form of questionnaires enquiring how they would perceive their personal dental care and their attitude towards dentist. Results: Self-perceived questionnaires in evaluating general public in age group of <30 and >30 shows, that people in age group more than 30 has good oral hygiene maintenance, whereas attitude toward dentist and attending dental problems were more among group less than 30 of age. Conclusions: I conclude that there must be more awareness created by public health dentist among people about various dental problems, their complications and the treatment needs. Hence, that people be aware of their dental problem at the small stage and get cured. By conducting varies Public Health Programs and camp they became very free to contact their dentist for their varies dental problems and people attitude about dentist and toward dentist completely changes.

Currently, the gold standard for dental imaging is projection radiography or cone-beam computed tomography (CBCT). These methods are fast and cost-efficient, but exhibit poor soft tissue contrast and expose the patient to ionizing radiation (X-rays). The need for an alternative imaging modality e.g. for soft tissue management has stimulated a rising interest in dental magnetic resonance imaging (MRI) which provides superior soft tissue contrast. Compared to X-ray imaging, however, so far the spatial resolution of MRI is lower and the scan time is longer. In this contribution, we describe wireless, inductively-coupled intraoral coils whose local sensitivity enables high resolution MRI of dental soft tissue. In comparison to CBCT, a similar image quality with complementary contrast was obtained ex vivo. In-vivo, a voxel size of the order of 250∙250∙500 μm3 was achieved in 4 min only. Compared to dental MRI acquired with clinical equipment, the quality of the images was superior in the sensitive volume of the coils and is expected to improve the planning of interventions and monitoring thereafter. This method may enable a more accurate dental diagnosis and avoid unnecessary interventions, improving patient welfare and bringing MRI a step closer to becoming a radiation-free alternative for dental imaging.

Background Anticoagulation therapy is used in several conditions to prevent or treat thromboembolism. Recently, new oral anticoagulants have been introduced as alternatives to warfarin and acenocoumarol. In Europe, the European Medicines Agency has approved dabigatran, rivaroxaban and apixaban. Their advantages include: predictable pharmacokinetics, drug interactions and limited food, rapid onset of action and short half-life. However, they lack a specific reversal agent. Material and Methods A literature search was conducted through November 2015 for publications in the ISI Web of Knowledge, PubMed, Scopus and Cochrane Library using the keywords “apixaban”, “rivaroxaban”, “dabigatran”, “new oral anticoagulants”, “dental treatment” and “dental implications”. We included studies published in English and Spanish over the last 10 years. Results Apixaban has been recently introduced in the daily medical practices for the control of thromboembolism. The number of patients taking apixaban is increasing. Management of patients on anticoagulation therapy requires that dentists can accurately assess the patient prior to dental treatments. It is important for dentists to have a sound understanding of the mechanisms of action and management guidelines for patients taking new oral anticoagulants. Conclusions The dentist should consider carefully the management of patients on apixaban. This paper sets out a clinical guidance of dental practitioners treating these patients. There is a need for further clinical studies in order to establish more evidence-based guidelines for dental patients requiring apixaban. Key words:Apixaban, new oral anticoagulants, dental treatment. PMID:27957279

The earliest reference to holographic applications appeared in the dental literature in 1972 when Wictorin, Bjelkhagen and Abramson described a method to study elastic deformation of defective gold solder joints in simulated fixed bridges. Their paper, published in the Swedish dental literature, offered a concise presentation of the interferometry technique which led to the development of other research applications of holographic interferometry(holometry) in dentistry. In this presentation, the development and application of the interferometry technique in the dental field will be discussed. Various interesting and potentially useful applications of holography have appeared in the dental literature over the past decade. Some of these, which will be discussed, include the use of holograms as a storage medium for dental study models, multiplexing of computer(CT) scan sections to form white light viewable holograms and the potential application of holographic training aids in the teaching of the basic courses of dental anatomy and restorative dentistry. In addition, some unique related applications will be mentioned including a laser reflection method for accurate non-contact measurement of tooth mobility/movement and a technique for contour mapping of occlusal surfaces to measure wear of restorative materials.

This study sought to evaluate the self-perceived response to dental care during prenatal assistance in the Unified Health System (SUS) in the Metropolitan Region of Vitória, Espírito Santo, Brazil. 1032 postpartum women were interviewed and 1006 prenatal records copied. Postpartum women's self-perceived response was measured by the Oral Health Index Profile-14. When an impact was identified, dental care rendered in educational, preventive and curative terms was considered adequate. When there was no impact, assistance was considered adequate in educational and preventive terms. The Chi-square test revealed an association between prenatal care and dental care. Oral health impact on quality of life was 14.7%. Dental care received by mothers in educational terms was rated at 41.3%, while in preventive terms it was 21% and in curative terms it was 16.6%. Six or more prenatal appointments coupled with educational activities was closely associated with adequate dental care (p < 0.05). Access to dental care is facilitated when pregnant women attend health services and become involved in educational activities during the prenatal period. Consequently, educational measures appear to indicate an improvement in prenatal care in the SUS.

Aim: At the annual meeting of German dentists in Frankfurt am Main in 2013, the Working Group for the Advancement of Dental Education (AKWLZ) initiated an interdisciplinary working group to address assessments in dental education. This paper presents an overview of the current work being done by this working group, some of whose members are also actively involved in the German Association for Medical Education's (GMA) working group for dental education. The aim is to present a summary of the current state of research on this topic for all those who participate in the design, administration and evaluation of university-specific assessments in dentistry. Method: Based on systematic literature research, the testing scenarios listed in the National Competency-based Catalogue of Learning Objectives (NKLZ) have been compiled and presented in tables according to assessment value. Results: Different assessment scenarios are described briefly in table form addressing validity (V), reliability (R), acceptance (A), cost (C), feasibility (F), and the influence on teaching and learning (EI) as presented in the current literature. Infoboxes were deliberately chosen to allow readers quick access to the information and to facilitate comparisons between the various assessment formats. Following each description is a list summarizing the uses in dental and medical education. Conclusion: This overview provides a summary of competency-based testing formats. It is meant to have a formative effect on dental and medical schools and provide support for developing workplace-based strategies in dental education for learning, teaching and testing in the future.

PURPOSE Dental implant has gained clinical success over last decade with the major drawback related to osseointegration as properties of metal (Titanium) are different from human bone. Currently implant procedures include endosseous type of dental implants with nanoscale surface characteristics. The objective of this review article is to summarize the role of nanotopography on titanium dental implant surfaces in order to improve osseointegration and various techniques that can generate nanoscale topographic features to titanium implants. MATERIALS AND METHODS A systematic electronic search of English language peer reviewed dental literature was performed for articles published between December 1987 to January 2012. Search was conducted in Medline, PubMed and Google scholar supplemented by hand searching of selected journals. 101 articles were assigned to full text analysis. Articles were selected according to inclusion and exclusion criterion. All articles were screened according to inclusion standard. 39 articles were included in the analysis. RESULTS Out of 39 studies, seven studies demonstrated that bone implant contact increases with increase in surface roughness. Five studies showed comparative evaluation of techniques producing microtopography and nanotopography. Eight studies concluded that osteoblasts preferably adhere to nano structure as compared to smooth surface. Six studies illustrated that nanotopography modify implant surface and their properties. Thirteen studies described techniques to produce nano roughness. CONCLUSION Modification of dental osseous implants at nanoscale level produced by various techniques can alter biological responses that may improve osseointegration and dental implant procedures.

Currently, the gold standard for dental imaging is projection radiography or cone-beam computed tomography (CBCT). These methods are fast and cost-efficient, but exhibit poor soft tissue contrast and expose the patient to ionizing radiation (X-rays). The need for an alternative imaging modality e.g. for soft tissue management has stimulated a rising interest in dental magnetic resonance imaging (MRI) which provides superior soft tissue contrast. Compared to X-ray imaging, however, so far the spatial resolution of MRI is lower and the scan time is longer. In this contribution, we describe wireless, inductively-coupled intraoral coils whose local sensitivity enables high resolution MRI of dental soft tissue. In comparison to CBCT, a similar image quality with complementary contrast was obtained ex vivo. In-vivo, a voxel size of the order of 250•250•500 μm3 was achieved in 4 min only. Compared to dental MRI acquired with clinical equipment, the quality of the images was superior in the sensitive volume of the coils and is expected to improve the planning of interventions and monitoring thereafter. This method may enable a more accurate dental diagnosis and avoid unnecessary interventions, improving patient welfare and bringing MRI a step closer to becoming a radiation-free alternative for dental imaging.
This series is based upon fact, experience, and some personal views of the author and gives a brief glimpse of forensic odontological issues with regard to the identification of human remains (to include mass fatality incidents), biting injuries and child abuse. The aim of the first paper is to give the reader greater understanding of the role of the forensic odontologist in the identification of human remains, and emphasise the importance of keeping good quality, accurate and comprehensive dental records. Identification of the deceased greatly assists families and friends at this difficult time, as well as aiding law enforcement agencies; getting it wrong is devastating to families and unacceptable. The dental identification process must be carefully undertaken and relies upon the comparison of information from the antemortem record with findings from the postmortem examination, and the efficiency of this process is dependent on the quality and availability of the dental record. As dental team members it is our responsibility to keep and maintain accurate records of our patients. The resilience of the dental structures to postmortem assault, denture labelling, and teeth as a source of DNA, all contribute to making identification successful. Dental identification is widely used, not only in the single fatality situation, but also in mass fatality incidents and cases of missing persons.

To offer individualized dental treatment to certain patients who cannot tolerate dental treatment, sedation or general anesthesia is required. The needs could be either medical, mental, or psychological. The most common indications for sedation or general anesthesia are lack of cooperation, multiple morbidities, and pediatric autism. In adults, cognitive impairment and multiple morbidities are most commonly encountered indications. Because of suboptimal home care, incomplete medical history, poor preoperative management, lack of cooperation, and developmental abnormalities, it is a challenge to prepare anesthesia for patients with special needs. The American Society of Anesthesiology (ASA) has proposed guidelines for office-based anesthesia for ambulatory surgery. In patients with ASA physical status IV and V, sedation or general anesthesia for treatment in the dental office is not recommended. The distinction between sedation levels and general anesthesia is not clear. If intravenous general anesthesia without tracheal intubation is chosen for dental procedures, full cooperation between the dentist, dental assistant, and anesthesiologist is needed. Teamwork between the dentist and healthcare provider is key to achieve safe and successful dental treatment under sedation or general anesthesia in the patient with special needs.

The high risk of occupational contact dermatitis in dental personnel are well accepted throughout the world. There are few reports concerning occupational skin disease in dental personnel in Korea. The purposes of this study were to investigate the frequency, characteristics and causative factors of contact dermatitis in Korean dental technicians. Recording of personal history, physical examination and patch tests with the Korean standard series and dental screening series were performed in 49 dental technicians. Most of the subjects were exposed to a variety of compounds, including acrylics, metals, plaster, alginate, etc. 22 (44.9%) subjects had contact dermatitis, present or past, and the site involved was the hand in all 22. The most common clinical feature of hand dermatitis was itching (77.3%); scaling, fissuring and erythema were other common clinical features. Metals, including potassium dichromate (24.5%), nickel sulfate (18.4%), mercury ammonium chloride (16.3%), cobalt chloride (12.2%) and palladium chloride (10.2%), showed high positive rates in patch test results of 49 dental technicians. 7 positive reactions to the various acrylics were found in 3 subjects. In our study, the frequency and clinical features of the contact dermatitis showed a similarity to other reports, though the patch test results were somewhat different; a higher patch-positive reaction to metals and a relatively lower patch-positive reaction to acrylics than the patch test results reported in Europe.

Objective The purpose of this article is to examine the relationship between changes in household finances (wealth and income) and changes in dental utilization at the onset of the recent recession in a population of older Americans. Methods Data from the Health and Retirement Study (HRS) were analyzed for U.S. individuals aged 51 years and older during the 2006 and 2008 waves of the HRS. We estimated logistic models of (1) starting and (2) stopping dental use between 2006 and 2008 survey periods as a function of changes in household wealth and income, controlling for other potentially confounding covariates. Results We found that only when household wealth falls by 50 percent or more were older adults less likely to seek dental care. Changes in household income and other changes in household wealth were not associated with changes in dental utilization among this population. Conclusions Older Americans’ dental care utilization appeared to be fairly resilient to changes in household finances; only when wealth fell by 50 percent or more did individuals decrease dental use. This finding might extend to other health care services that are preventive, routine, and relatively inexpensive. PMID:22994647

Since 1939, it has been known that, silicosis and extrinsic allergic alveolitis can be seen among dental technicians. The interstitial disease caused by the exposure to complex substances used by dental technicians is classified as a special group called dental technician's pneumoconiosis. A 36-year-old man, who has no smoking history, presented with severe dyspnea. He had worked in different dental laboratories for 22 years, but he did not have respiratory symptoms until five years ago. After that date, he had hospitalized and had been examined for respiratory pathologies for many times. He had came to our clinic, because of the progression of his dyspnea. Diffuse pulmonary parenchymal infiltrates which can be related with pneumoconiosis and chronic type 1 respiratory deficiency had been diagnosed as the result of the examinations. While he has no history of smoking or any other risk factors or diseases in his medical history, the case was accepted as dental technician's pneumoconiosis. The factors related with the pathogenesis of dental technician's pneumoconiosis are; the complex compound of the substances (metal dusts, silica, plaster, wax and resins, chemical liquids, methyl methacrylate) used in this sector and their effects on the lung parenchyma. Extrinsic allergic alveolitis related with methyl methacrylate has been reported. The most important factor to acquire an occupational lung disease is a complex occupational exposure. The insufficient workplace airing and the lack of preventive measures added on this exposure, the risks become much more greater.

Transfusion transmitted virus (TTV) is a new DNA virus found in patients with post-transfusion hepatitis. The prevalence of this virus among dental patients has not been reported, therefore, the prevalence of TTV infection in consecutive dental inpatients was evaluated. TTV DNA was assayed by the polymerase chain reaction (PCR) in 441 dental inpatients with oral cancer (n=192) or oral cysts (n=249). The serum HBs antigen and HCV antibody as well as aspartate transaminase (AST), alanine transaminase (ALT), and gamma glutamyl transpeptidase (gamma-GTP) concentrations were also measured. Of 441 subjects, 137 were infected with TTV (31.1%). This prevalence of TTV was much higher than that of HBV or HCV (HBV 1.2%; HCV 6.0%) in these dental patients. There was no gender or age difference in the prevalence of TTV infection. Of the 192 patients with oral cancer, 57 subjects had TTV in their sera, while 80 of 249 with oral cystic disease had TTV. The prevalence of TTV was similar between the two different disease groups. Neither the serum ALT nor serum AST concentrations were different between the subjects positive and negative for TTV DNA. In hospitalized dental patients, 31.1% were infected with TTV. The prevalence of TTV was much higher than that of HBV or HCV. There was no difference in the prevalence of TTV between subjects with cancer and cysts. Dentists should maintain high standards of infection control when treating any dental patient.

A collaborative relationship between prosthodontists and dental technicians can greatly improve the esthetic and functional results of restorations. When each discipline takes the time to understand the strengths and challenges of the other, together they can formulate a treatment plan that will culminate in a successful result. The diagnostic waxup gives the dental team a three-dimensional illustration of the problem and allows the patient to view the problem and discuss solutions. Intraoral records taken by the prosthodontist are used with the technician's centric relation jigs to properly mount the casts. When the prosthodontist and technician agree on materials to be used in the fabrication of the provisional prosthesis and master dies, more accurate and functional results are achieved. Of special interest are the tooth preparations: The shape of the margins can enable the dental technician to easily create an accurate restoration. A treatment waxup allows full communication of information about the restoration between the prosthodontist, dental technician, and patient, ensuring that all three parties are satisfied with the look and function before the definitive restoration is made. The type of material and the color properties for the definitive restoration are of utmost importance, and the combined skills and experience of the prosthodontist and dental technician can create an excellent result. This article defines specific points in the restorative process when a collaborative effort between the prosthodontist and the dental technician dramatically improve the end result.

Objectives: The aims of this study were to investigate the incidence of bacteremia, bacteriology and antibiotic susceptibility against to causative bacteria associated with dental implant installation. Study Design: 30 generally healthy patients were enrolled in this study. Blood samples were collected at baseline and at 30 minutes after dental implant installation and 24 hours after dental implant surgery. Blood samples were cultured in a BACTEC system. The isolated bacteria were identified using conventional methods. Antimicrobial sensitivity tests were performed by disc diffusion. Results: No bacteria were isolated at the baseline and 24 hours after surgery, whereas the prevalence of bacteremia at 30 minutes after dental implant installation was 23%. The isolated bacteria species were Staphylococcus epidermidis, Eubacterium spp., Corynebacterium spp. and Streptococcus viridans. The Staphylococcus epidermidis, which was isolated in three patients, was found to be resistant to penicillin which is first choice of many clinicians. Conclusion: Our findings suggest that installation of dental implants can produce bacteremia. Within the limitations of this study, it can be speculated that the resistance of antibiotics may compromise the routine prophylaxis against infective endocarditis. Therefore use of blood cultures and antibiograms may be suggested in risky patients. The outcome of the present study should be verified using a larger patient group with varying conditions. Key words: Dental implant, bacteremia, infective endocarditis, antibiotic prophylaxis. PMID:22157668

Forensic dental identification of casualties during Operation Desert Storm was performed at the Dover Port Mortuary, Dover Air Force Base, under the auspices of the Office of the Armed Forces Medical Examiner. A total of 251 dental identifications were attempted and 244 individuals were positively identified by dental comparison. The panoramic radiographs on file at the Central Panograph Storage Facility were the primary antemortem records utilized in establishing the dental identification. The inability to establish a positive dental identification was most often the result of a lack of available antemortem dental records.

This study evaluated the effect of dental education on oral health-related attitudes and behavior of students in a five-year dental program in Peru. A survey using the Hiroshima University-Dental Behavioral Inventory (HU-DBI), which consists of twenty dichotomous responses (agree-disagree) regarding oral health behavior and attitudes, was completed by Year 1 and Year 5 dental students at the Universidad Inca Garcilaso de la Vega in Lima, Peru. A total of 153 Year 1 students and 120 Year 5 students responded to the Spanish version of the HU-DBI questionnaire. The data were analyzed using chi-square tests and logistic regression analyses. Compared to the Year 1 students, the Year 5 dental students were more likely to agree with questions such as “I think I can clean my teeth well without using toothpaste” (OR=0.24, 95% CI: 0.10-0.58); “I have used a dye to see how clean my teeth are” (OR=0.19, 95% CI: 0.10-0.36); and “I have had my dentist tell me that I brush very well” (OR=0.34, 95% CI: 0.17-0.69). Overall, the data showed that the curriculum in this dental school in Peru resulted in more positive oral health-related attitudes and behavior among Year 5 dental students compared to those of Year 1 dental students.

In the United States, occupational regulations influence the work tasks that may legally be performed by dentists and dental hygienists. Only a dentist may legally perform most dental procedures; however, a smaller list of basic procedures may be provided by either a dentist or a dental hygienist. Since dentists and hygienists possess different levels of training and skill and receive very different wages, it is plausible that these regulations could distort the optimal allocation of skills to work tasks. We present simple theoretical framework that shows different ways that such regulations might affect the way that dentists and dental hygienists are used in the production of dental services. We then use a large database of dental insurance claims to study the effects of the regulations on the prevailing prices of a set of basic dental services. Our empirical analysis exploits variation across states and over time in the list of services that may be provided by either type of worker. Our main results suggest that the task-specific occupational regulations increase prices by about 12%. We also examine the effects of related occupational regulations on the utilization of basic dental services. We find that allowing insurers to directly reimburse hygienists for their work increases one year utilization rates by 3-4 percentage points.

The purpose of the present study was to assess the utilization pattern of dental services in a group of Pakistani immigrants in Norway. Use was related to sociodemographic characteristics, level of urbanization in Pakistan, knowledge and belief about dental diseases and evaluated and perceived dental health. A total of 160 immigrants were clinically examined and interviewed by a structured questionnaire. The effect change analysis was performed, and separate analyses were performed for men and women. Altogether 60% had visited the dentist during the last 3 yr. While 69% coming from the cities had been to the dentist in Norway, this was the case for only 38% of those from the villages of Pakistan. Pain was given as the main reason for dental visits, and the data indicated insufficient ability to perform self-assessment of own dental health. The independent variables could explain more of the variance in use of dental services among the Pakistani men (R2 = 40%) than among the women (R2 = 21%). While number of decayed teeth and level of urbanization were among the strongest predictors among the men, dental behavior in Pakistan and number of years in Norway were of importance among the women. The latter variable indicated that the women in terms of dental behavior had a higher degree of acculturation than the men, leading to a change in traditional health behavior.

The challenges of health care are increasingly complex and subject to frequent change. Meeting these demands requires that health professionals work in partnership with each other and the patient. One way of contributing to this is for students to learn together. However, effective teamwork requires an education system that helps to foster understanding among all those entering the health workforce. The purpose of this study was to investigate the attitudes towards shared learning of undergraduate dental students and trainee dental technicians in a university dental school/hospital in the United Kingdom. Twenty-five trainee dental technicians and 75 undergraduate dental students took part in the study over five academic years. Data were collected using structured questionnaires. A 100% response rate was achieved from the questionnaires. The results indicated the majority of students recognized the benefits of shared learning and viewed the acquisition of teamworking skills as useful for their future working lives, beneficial to the care of their patients, and likely to enhance professional working relationships. The study also found a positive association of being valued as an individual in the dental team by all student groups. Future dental curricula should provide opportunities to develop effective communication between these two groups and encourage teamworking opportunities. These opportunities need to be systematically developed in the dental curriculum to achieve the desired goals.

What can the study of ancient teeth tell us about the dietary habits of our ancestors? Diet plays a prominent role in the organisation and evolution of human cultures and an increasingly diverse array of analytical techniques are available to help reconstruct diet in ancient populations. Dental palaeopathology is particularly important as it can provide direct evidence of the type of diet an individual consumed during life. Heavy occlusal tooth wear is the most frequent condition recognisable and an examination of both macro and microscopic patterns of wear can establish the differences between the hard fibrous diet typical of a hunter-gatherer, and a diet primarily consisting of softer plant foods consumed by an agriculturist. The distributions of trace elements and stable isotopes in food webs make it possible to use them as natural tracers of foodstuffs. Through a consideration of photosynthetic pathways, the ratios of the different stable isotopes of carbon and nitrogen can determine which specific groups of plants and animals were dominant in the food chains of various populations - a fact that has been used to trace the spread of agriculture in ancient civilisations.

Becoming a dental professional requires one to apply ethical decision making skills and demonstrate high standards of professionalism in practice, including the way professionals present themselves to the public. With social media as an evergrowing part of personal and professional communications, this study aimed to determine the accessibility, amount, and type of unprofessional content on Facebook profiles of dental hygiene and dental students in a college of dentistry. The authors evaluated the online profiles of all 499 dental and dental hygiene students at The Ohio State University using objective measures that included existence of a profile, current privacy settings, and access to personally identifiable information. A sample of profiles were evaluated for unprofessional content including photos, comments, and wall posts. The majority of these students were found to use Facebook, with 61 percent having Facebook profiles. Dental hygiene students were more likely to have a Facebook profile than were dental students: 72.6 percent and 59.1 percent, respectively (p=0.027). The majority of the students' profiles had some form of privacy setting enabled, with only 4 percent being entirely open to the public. Fewer than 2 percent of the students allowed non-friends access to personal information. Based on in-depth analysis of the profiles, fourteen (5.8 percent) instances of unprofessionalism were recorded; the most common unprofessional content involved substance abuse. This study found that these dental and dental hygiene students frequently possessed an identifiable Facebook account and nearly half had some kind of personal information on their profile that could potentially be shared with the public. In some instances, the students gave patients, faculty, and potential employers access to content that is not reflective of a dental professional. Academic institutions should consider implementing policies that bring awareness to and address the use of social media

Aims and Objectives: Biomedical waste management has become a concern with increasing number of dental practitioners in India. Being health care professionals, dentists should be aware regarding safe disposal of biomedical waste and recycling of dental materials to minimize biohazards to the environment. The aim of the present study was to assess awareness regarding biomedical waste management as well as knowledge of effective recycling and reuse of dental materials among dental students. Materials and Methods: This cross-sectional study was conducted among dental students belonging from all dental colleges of Bhubaneswar, Odisha (India) from February 2016 to April 2016. A total of 500 students (208 males and 292 females) participated in the study, which was conducted in two phases. A questionnaire was distributed to assess the awareness of biomedical waste management and knowledge of effective recycling of dental materials, and collected data was examined on a 5-point unipolar scale in percentages to assess the relative awareness regarding these two different categorizes. The Statistical Package for Social Sciences was used to analyzed collected data. Results: Forty-four percent of the dental students were not at all aware about the management of biomedical waste, 22% were moderately aware, 21% slightly aware, 7% very aware, and 5% fell in extremely aware category. Similarly, a higher percentage of participants (61%) were completely unaware regarding recycling and reusing of biomedical waste. Conclusion: There is lack of sufficient knowledge among dental students regarding management of biomedical waste and recycling or reusing of dental materials. Considering its impact on the environment, biomedical waste management requires immediate academic assessment to increase the awareness during training courses. PMID:27891315

The following article has been prepared by the American Dental Association (ADA) at the request of the Minnesota Dental Association (MDA). The article is the culmination of a rigorous national study by the ADA to measure the concentration of dental insurance in major dental marketplaces around the country. Five Metropolitan Statistical Areas (MSA's)from Minnesota were compared to other MSA's around the country. The results of this study are very significant for dentists and dental patients in Minnesota. Minnesota' practicing dental community may find the results of the study to be somewhat disturbing. Nevertheless, the MDA believes that it is important to share the results of this study with MDA members and others in the Minnesota dental community. It is important to consider both the study's short-term ramifications, as well as its long-term implications, as we attempt to better understand Minnesota's dental marketplace. It is also important for MDA members to know that the ADA brought the results of this study as they relate to the Minnesota Dental Marketplace to the appropriate federal agencies. The ADA believed that these agencies might choose to develop it into an anti-trust case. After reviewing the matter and working with the ADA over a long period of time, these agencies decided that they would not proceed with a Minnesota-based anti-trust case; additional information beyond what the ADA was legally able to provide was needed by the federal agencies in order for them to proceed. The MDA will continue to analyze and respond to these dental marketplace developments.

The global market for dental materials is predicted to exceed 10 billion dollars by 2020. The main drivers for this growth are easing the workflow of dentists and increasing the comfort of patients. Therefore, remarkable research projects have been conducted and are currently underway to develop improved or new dental materials with enhanced properties or that can be processed using advanced technologies, such as CAD/CAM or 3D printing. Among these materials, zirconia, glass or polymer-infiltrated ceramics, and glass-ceramics (GCs) are of great importance. Dental glass-ceramics are highly attractive because they are easy to process and have outstanding esthetics, translucency, low thermal conductivity, high strength, chemical durability, biocompatibility, wear resistance, and hardness similar to that of natural teeth, and, in certain cases, these materials are bioactive. In this review article, we divide dental GCs into the following two groups: restorative and bioactive. Most restorative dental glass-ceramics (RDGCs) are inert and biocompatible and are used in the restoration and reconstruction of teeth. Bioactive dental glass-ceramics (BDGCs) display bone-bonding ability and stimulate positive biological reactions at the material/tissue interface. BDGCs are suggested for dentin hypersensitivity treatment, implant coating, bone regeneration and periodontal therapy. Throughout this paper, we elaborate on the history, processing, properties and applications of RDGCs and BDGCs. We also report on selected papers that address promising types of dental glass-ceramics. Finally, we include trends and guidance on relevant open issues and research possibilities. © 2016 Wiley Periodicals, Inc. J Biomed Mater Res Part A: 105A: 619-639, 2017.

Introduction Altmetrics is a new and emerging scholarly tool that measures online attention surrounding journal articles. Altmetric data resources include: policy documents, news outlets, blogs, online reference managers (eg Mendeley and CiteULike), post-publication peer-review forums (eg PubPeer and Publons), social media (eg Twitter, Facebook, Weibo, Google(+), Pinterest, Reddit), Wikipedia, sites running Stack Exchange (Q&A), and reviews on F1000 and YouTube.Methods To identify the top 50 dental articles in 2014, PubMed was searched using the following query "("2014/1/1"[PDAT]:"2014/12/31"[PDAT]) and jsubsetd[text]" in December, 2015. Consequently, all PubMed records were extracted and sent to Altmetric LLP (London, UK) as a CSV file for examination. Data were analysed by Microsoft Office Excel 2010 using descriptive statistics and charts.Results Using PubMed searches,15,132 dental articles were found in 2014. The mean Altmetric score of 50 top dental articles in 2014 was 69.5 ± 73.3 (95% CI: -74.14 to 213.14). The British Dental Journal (48%) and Journal of Dental Research (16%) had the maximum number of top articles. Twitter (67.13%), Mendeley (15.89%) and news outlets (10.92%) were the most popular altmetric data resources.Discussion Altmetrics are intended to supplement bibliometrics, not replace them. Altmetrics is a fresh and emerging arena for the dental research community. We believe that dental clinical practitioners, research scientists, research directors and journal editors must pay more attention to altmetrics as a new and rapid tool to measure the social impact of scholarly articles.

Occupational regulation of health personnel is important to professional associations and their members, the public that relies on their services and the regulatory agencies responsible for their conduct. There is increasing interest in ensuring that dental hygiene regulation fosters the continuing evolution of the profession and its contribution to oral health. The keynote address for the 2007 Regulatory Forum on Dental Hygiene, this paper discusses the rationale for and issues pertaining to occupational regulation, outlines the evolvement of dental hygiene and identifies regulatory options for the profession. Professional regulation exists to ensure public safety, health and welfare. However, negative political-economic side effects coupled with environmental pressures have resulted in increased scrutiny for health professionals. One such profession is dental hygiene. Its evolution has been dramatic, in particular over the past few decades, as illustrated by its rapidly increasing numbers and broader distribution globally, gradual shift to the baccalaureate as the entry-level educational requirement and increase in postgraduate programs and expanding scope of practice and increased professional autonomy. Regulatory changes have been more gradual. Regulation is mandatory for the vast majority of dental hygienists. Of the options available, the practice act - the most rigorous type, is predominant. Globally, regulation tends to be administered directly by the government (n = 9 countries) more so than indirectly through a dental board (n = 4) or self-regulation (n = 3). Whether regulated directly or indirectly, dental hygienists increasingly are seeking a greater role in shaping their professional future. Self-regulation, its responsibilities, misperceptions and challenges, is examined as an option.

Water samples collected from 28 dental facilities in six U.S. states were examined for the presence of Legionella pneumophila and other Legionella spp. by the PCR-gene probe, fluorescent-antibody microscopic, and viable-plate-count detection methods. The PCR and fluorescent-antibody detection methods, which detect both viable and viable nonculturable Legionella spp., gave higher counts and rates of detection than the plate count method. By the PCR-gene probe detection method, Legionella spp. were detected in 68% of the dental-unit water samples and L. pneumophila was detected in 8%. Concentrations of Legionella spp. in dental-unit water reached 1,000 organisms per ml or more in 36% of the samples, and 19% of the samples were in the category of 10,000/ml or above. L. pneumophila, when present in dental-unit water, never reached concentrations of 1,000/ml or more. Microscopic examination with fluorescent-antibody staining indicated that the contamination was in the dental-unit water lines rather than in the handpieces. Legionella spp. were present in 61% of potable water samples collected for comparative analysis from domestic and institutional faucets and drinking fountains; this percentage was not significantly different from the rate of detection of Legionella spp. in dental-unit water. However, in only 4% of the potable water samples did Legionella spp. reach concentrations of 1,000 organisms per ml, and none was in the 10,000 organisms-per-ml category, and so health-threatening levels of Legionella spp. in potable water were significantly lower than in dental-unit water. L. pneumophila was found in 2% of the potable water samples, but only at the lowest detectable level.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7747943

In this study, the grindability of cast magnetic alloys (Fe-Pt-Nb magnetic alloy and magnetic stainless steel) was evaluated and compared with that of conventional dental casting alloys (Ag-Pd-Au alloy, Type 4 gold alloy, and cobalt-chromium alloy). Grindability was evaluated in terms of grinding rate (i.e., volume of metal removed per minute) and grinding ratio (i.e., volume ratio of metal removed compared to wheel material lost). Solution treated Fe-Pt-Nb magnetic alloy had a significantly higher grinding rate than the aged one at a grinding speed of 750-1500 m x min(-1). At 500 m x min(-1), there were no significant differences in grinding rate between solution treated and aged Fe-Pt-Nb magnetic alloys. At a lower speed of 500 m x min(-1) or 750 m x min(-1), it was found that the grinding rates of aged Fe-Pt-Nb magnetic alloy and stainless steel were higher than those of conventional casting alloys.

Lactobacilli have been associated with dental caries for over a century. Here, we review the pertinent literature along with findings from our own study to formulate a working hypothesis about the natural history and role of lactobacilli. Unlike most indigenous microbes that stably colonize a host, lactobacilli appear to be planktonic, opportunistic settlers that can gather and multiply only in certain restrictive niches of the host, at least within the oral cavity. We postulate that the following essential requirements are necessary for sustained colonization of lactobacilli in humans: 1) a stagnant, retentive niche that is mostly anaerobic; 2) a low pH milieu; and 3) ready access to carbohydrates. Three sites on the human body meet these specifications: caries lesions, the stomach, and the vagina. Only a handful of Lactobacillus species is found in caries lesions, but they are largely absent in caries-free children. Lactobacilli present in caries lesions represent both a major contributor to caries progression and a major reservoir to the gastrointestinal (GI) tract. We extend the assertion from other investigators that lactobacilli found in the GI tract originate in the oral cavity by proposing that lactobacilli in the oral cavity arise from caries lesions. This, in turn, leads us to reflect on the health implications of the lactobacilli in the mouth and downstream GI and to ponder whether these or any of the Lactobacillus species are truly indigenous to the human GI tract or the oral cavity.

Spasmodic torticollis or cervical dystonia (CD) is the most common form of focal dystonia and is characterized by sustained abnormal muscle contractions in the head and neck area resulting in abnormal positioning or posturing of the head. The dystonic muscle spasms associated with spasmodic torticollis may affect any combination of neck muscles. Three cases are reported of spasmodic torticollis that were treated by a dental appliance with individual varying occlusal heights to open the maxillomandibular vertical dimension. Upon increasing the vertical dimension of occlusion, there was a slowing and/or discontinuance of the symptoms of cervical dystonia. The proposed hypothesis for this reversal is that there may be neuritis of the auriculotemporal branch of the trigeminal nerve, which has direct input into the reticular formation (RF), and it may activate the cells of the pontine region of the RF known for the control and deviation of head posture. There is growing clinical evidence that temporomandibular joint (TMJ) dysfunction may be a factor in this neurological and painful disorder when it coexists.
From an outline of a general model of inequalities in oral health, three main issues are addressed: (1) Self-perceived oral health; (2) Utilization of dental care; and (3) Satisfaction with dental care. The aim was to study these aspects in relation to each other as well as aspects such as socio-economic factors, health factors, and attitudes to teeth and care organization. Another aim was to study changes between the two study years. The study is a questionnaire study of a longitudinal sample: people born in 1942 and at the time of the studies living in Orebro or Ostergötland county in Sweden. A cohort (5363 persons) was established with those who completed the questionnaire in both 1992 and 1997. The main results were that there were social differences in self-perceived oral health, with those born outside Sweden, those living single, those with lower level of education and those being blue-collar worker perceiving worse oral health. Changes between the two study years were moderate despite major cutbacks in dental care insurance during this period. Socio-economic factors affected dental care utilization as well. Having a private care provider gave higher utilization and higher cost for care. Health perception, both oral and general health, and dental anxiety also affected utilization. Increasing patient cost for care did not appreciably affect utilization. The overall satisfaction with dental care was high, both in general terms and with the most recent dental visit. Differences between the two studied years were small. Persons not visiting dental care within the last year were more dissatisfied, both generally and with the most recent visit. A large number of regular attenders had no feelings of anxiety, pain or unpleasantness at all. Oral health related factors and dental care factors such as cost for care and care organization were related to satisfaction with dental care. So were experiences from the most recent dental visit and, to some extent, past care
