    Full Text Available Dental bleaching occurs due to an oxidation reaction between the bleaching agents and the macromolecules of pigments in the teeth. This reaction is unspecific and the peroxides can also affect the dental matrix causing mineral loss. On the other hand, recent studies have suggested that the thickener agent carbopol can also cause mineral loss. Thus, the objective of this study was to evaluate in vitro the effect of at-home dental bleaching on dental enamel microhardness after the use of bleaching agents with and without carbopol as a thickener agent. Bovine dental slabs with 3 x 3 x 3 mm were obtained, sequentially polished, and randomly divided into 4 groups according to the experimental treatment: G1: 2% carbopol; G2: 10% carbamide peroxide with carbopol; G3: carbowax; G4: 10% carbamide peroxide with poloxamer. Bleaching was performed daily for 4 weeks, immersed in artificial saliva. Enamel microhardness values were obtained before the treatment (T0 and 7 (T1, 14 (T2, 21 (T3, 28 (T4, and 42 (T5 days after the beginning of the treatment. ANOVA and Tukey's test revealed statistically significant differences only for the factor Time (F = 5.48; p O clareamento dental ocorre devido a uma reação de oxidação entre o agente clareador e as macromoléculas de pigmentos presentes nos dentes. Esta reação é inespecífica e o peróxido pode agir na matriz dental causando perdas de mineral. Por outro lado, estudos recentes sugerem que o agente espessante carbopol também pode causar perda mineral. Assim, o objetivo deste trabalho foi avaliar in vitro o efeito do clareamento caseiro sobre a microdureza do esmalte após o uso de agentes clareadores com e sem carbopol como espessante. Fragmentos de esmalte bovino de 3 x 3 x 3 mm foram obtidos, polidos seqüencialmente e aleatoriamente divididos em 4 grupos de acordo com o tratamento experimental: G1: carbopol a 2%; G2: peróxido de carbamida a 10% com carbopol; G3: carbowax; G4: peróxido de carbamida a

    The aim of this study was to evaluate the intra-pulpal temperature change, as well as to compare the bleaching power of a 38% hydrogen peroxide (Opalescence Xtra Boost- Ultradent. Inc), when activated with a diode laser, with a LED system and without activation, in the extrinsic tooth bleaching in vitro. Ten mandibular human incisors, a thermocouple, 45 bovine incisors and a spectrophotometer (Shade Eye- Shofu) for the color analysis. The samples were divided into 3 groups: 38% hydrogen peroxide activated by a diode laser (ZAP lasers, wavelength 808 nm {+-} 5, power of 1,4 W); 38% hydrogen peroxide activated by LED (Bright LEC-Mmoptics, wavelength 470 nm {+-} 25, power of 380 mW); 38% hydrogen peroxide without activation. After the artificial pigmentation, the bleaching agent acted for the same time in the 3 groups, differing only by the type of activation. The results of temperature showed that the LED activation was safer than the diode laser, which, in some measures exceeded the limit of 5.6 deg C. The luminosity of the samples did not show significantly statistics differences in none of the groups and moments of this study. The diode laser and LED activation did not influenced at the bleaching power of the peroxide, which showed effective for removing stains, with great capacity of bleaching bovine tooth artificially darkened.

    Full Text Available Os autores testaram a resistência ao cisalhamento de dentes submetidos a duas técnicas de clareamento. Foram utilizados 50 incisivos centrais superiores, divididos em 5 grupos, a saber: controle (só abertura coronária, clareamento sem calor, clareamento catalisado por calor controlado, clareamento catalisado por calor controlado e restauração com resina composta de última geração e dentes hígidos. Após o teste de cisalhamento, constatou-se que, nos dentes submetidos ao clareamento dental com perborato de sódio/Peridrol com ou sem aplicações de calor controlado, apesar de estes apresentarem leve diminuição da resistência ao cisalhamento, esta não é estatisticamente significante quando comparada com a dos dentes em que se executa o acesso endodôntico sem clareamento. A restauração do dente após o clareamento dental com adesivo dentinário de 4ª geração e resina fotopolimerizada aumenta a resistência do elemento dental clareado. Não existem diferenças estatísticas de resistência ao cisalhamento entre dentes clareados sem o uso de calor e aqueles em que o calor foi empregado de forma controlada, como preconizado neste estudo. Dentes hígidos apresentam resistência maior do que os dentes clareados com calor, sem calor e aqueles não clareados, com significância estatística no nível de 5%. Já com os dentes clareados e restaurados, os dentes hígidos não mostraram diferenças estatísticas significantes

A partir da análise documental e da realização de entrevistas (semiestruturadas com cirurgiões dentistas formados há dez ou mais anos, o estudo recorreu a uma abordagem qualitativa, ancorada na análise temática. No âmbito do ensino da periodontia, o estudo evidenciou que a presença da pigmentação fisiológica é omitida ou tratada como uma alteração de normalidade e/ou antiestética. Todos os entrevistados aprenderam a realizar o clareamento gengival em nível de pós-graduação, sendo estimulados a ofertar tal procedimento em nome de um sorriso saudável e bonito. Diante da supervalorização da eficiência da técnica, ressalta a ausência da discussão da questão estética na perspectiva étnica. Parece que a oferta do clareamento gengival se faz norteada pelo padrão branco de beleza, evidenciando o caráter etnocêntrico do procedimento.The aim of this study was to identify buccal/gingival cosmetic dentistry patterns subjacent to formation and professional practice of the dental surgeon from the ethnocentrism point of view. This is an exploratory study with a qualitative approach based on the thematic analysis. Initially a documental analysis was carried out. Thereafter, dental surgeons were interviewed and semi-structured questions were applied. In the Periodontal teaching field, this study showed that the presence of racial melanosis is omitted or treated as an alteration in the normality patterns and it is considered anti-aesthetic. All the interviewers learnt how to practice gingival bleaching in the post-graduation courses, they were all encouraged to offer this cosmetic dentistry procedure with the opportunity of obtaining a beautiful and healthy smile, thus assuring the belief of the Caucasian racial aesthetic superiority.

    This in vitro study evaluated the efficacy of LED and laser diode irradiation during the dental bleaching procedure, using two bleaching agents (Opalescence X-tra and HP Whiteness). The diode laser and the LED were operated in the continuous mode, with wavelength of 808 nm and 470 nm, respectively. The results of the irradiations were characterized with the CIELAB system calculating the L{sup *}a{sup *}b{sup *} values for the darkened and the bleached teeth (60 bovine incisors). This is to our knowledge the first time that light sources laser and LED are compared with respect to their whitening capability when applied to different agents. Significant differences in the chroma value are obtained for the two whitening agents and for the different light sources, too. Also, in terms of luminance, the combination of laser/ Whiteness HP showed significantly better results than when the same agent was used alone or in combination with LED. Best overall results are obtained with the combination of Whiteness HP and laser. (author)

    The laser enamel bleaching is a common used procedure due to its satisfactory esthetic results. The possible changes on the dental structures caused by the bleaching technique are of great importance. The enamel superficial microhardness changes through instrumented indentation hardness on bovine teeth were analyzed in this present study. The samples were divided in two halves, one being the control and the other irradiated with a diode laser (808 nm) or with a Nd:YAG laser (1064 nm) to activate the Whiteness HP bleaching gel (hydrogen peroxide at 35%). It was possible to conclude that there was a statistical significant increase on the enamel superficial microhardness (Group I, sample 1 and Group II, sample 1) despite this increase did not seem to indicate a concern regarding the enamel surface resistance change. There was not a significant statistical change on the enamel microhardness on the other samples. The final conclusion is that there was no superficial enamel morphological change after these treatments. (author)

    Full Text Available It has been reported that bond strength of resin to tooth structure can be reduced when the bonding procedure is carried out immediately after the bleaching treatment. This study evaluated the effect of bleaching of non-vital teeth bleaching on the shear bond strength (SBS of composite resin/bovine dentin interface and the influence of delaying the bonding procedures for different time intervals following internal bleaching. According to a randomized block design, composite resin cylinders (Z100/Single bond - 3M were bonded to the flattened dentin surface of two hundred and fifty-six teeth which had previously been subjected to four different treatments: SPH - sodium perborate + 30% hydrogen peroxide; SPW - sodium perborate + distilled water; CP - 37% carbamide peroxide; and CON - distilled water (control, each one followed by storage in artificial saliva for 0 (baseline, 7, 14, and 21 days after bleaching (n = 16. The bleaching agents in the pulp chambers were replaced every 7 days, over 4 weeks. The SBS test of the blocks was done using a universal testing machine. The ANOVA showed that there was no significant interaction between time and bleaching agents, and that the factor time was not statistically significant (p > 0.05. For the factor bleaching treatment, the Student's t-test showed that [CON = CP] > [SPW = SPH]. The bleaching of non-vital teeth affected the resin/dentin SBS values when sodium perborate mixed with 30% hydrogen peroxide or water was used, independently of the elapsed time following the bleaching treatment.Tem-se sugerido que a qualidade da adesão resina composta-dentina pode ser prejudicada quando restaurações são confeccionadas imediatamente após o tratamento clareador.

    Dental radiology is the core diagnostic modality of veterinary dentistry. Dental radiographs assist in detecting hidden painful pathology, estimating the severity of dental conditions, assessing treatment options, providing intraoperative guidance, and also serve to monitor success of prior treatments. Unfortunately, most professional veterinary training programs provide little or no training in veterinary dentistry in general or dental radiology in particular. Although a technical learning curve does exist, the techniques required for producing diagnostic films are not difficult to master. Regular use of dental x-rays will increase the amount of pathology detected, leading to healthier patients and happier clients who notice a difference in how their pet feels. This article covers equipment and materials needed to produce diagnostic intraoral dental films. A simplified guide for positioning will be presented, including a positioning "cheat sheet" to be placed next to the dental x-ray machine in the operatory. Additionally, digital dental radiograph systems will be described and trends for their future discussed.

    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.

    Dental caries is a biofilm-mediated, sugar-driven, multifactorial, dynamic disease that results in the phasic demineralization and remineralization of dental hard tissues. Caries can occur throughout life, both in primary and permanent dentitions, and can damage the tooth crown and, in later life......, exposed root surfaces. The balance between pathological and protective factors influences the initiation and progression of caries. This interplay between factors underpins the classification of individuals and groups into caries risk categories, allowing an increasingly tailored approach to care.

  6. Dental Calculus Arrest of Dental Caries.

    Keyes, Paul H; Rams, Thomas E

    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. 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. 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. These observations further document the potential protective effects of dental calculus mineralization against dental caries.

    Dental caries, otherwise known as tooth decay, is one of the most prevalent chronic diseases of people worldwide; individuals are susceptible to this disease throughout their lifetime. Dental caries forms through a complex interaction over time between acid-producing bacteria and fermentable carbohydrate, and many host factors including teeth and saliva. The disease develops in both the crowns and roots of teeth, and it can arise in early childhood as an aggressive tooth decay that affects the primary teeth of infants and toddlers. Risk for caries includes physical, biological, environmental, behavioural, and lifestyle-related factors such as high numbers of cariogenic bacteria, inadequate salivary flow, insufficient fluoride exposure, poor oral hygiene, inappropriate methods of feeding infants, and poverty. The approach to primary prevention should be based on common risk factors. Secondary prevention and treatment should focus on management of the caries process over time for individual patients, with a minimally invasive, tissue-preserving approach.

    Dental caries is a biofilm-mediated, sugar-driven, multifactorial, dynamic disease that results in the phasic demineralization and remineralization of dental hard tissues. Caries can occur throughout life, both in primary and permanent dentitions, and can damage the tooth crown and, in later life, exposed root surfaces. The balance between pathological and protective factors influences the initiation and progression of caries. This interplay between factors underpins the classification of individuals and groups into caries risk categories, allowing an increasingly tailored approach to care. Dental caries is an unevenly distributed, preventable disease with considerable economic and quality-of-life burdens. The daily use of fluoride toothpaste is seen as the main reason for the overall decline of caries worldwide over recent decades. This Primer aims to provide a global overview of caries, acknowledging the historical era dominated by restoration of tooth decay by surgical means, but focuses on current, progressive and more holistic long-term, patient-centred, tooth-preserving preventive care.

    Full Text Available Objective. To assess the prevalence and level of dental fear among health related undergraduates and to identify factors causing such fear using Kleinknecht’s Dental Fear Survey (DFS questionnaire. Methods. Kleinknecht’s DFS questionnaire was used to assess dental fear and anxiety among the entire enrollment of the medical and dental undergraduates’ of the University of Malaya. Results. Overall response rate was 82.2%. Dental students reported higher prevalence of dental fear (96.0% versus 90.4%. However, most of the fear encountered among dental students was in the low fear category as compared to their medical counterpart (69.2 versus 51.2%. Significantly more medical students cancelled dental appointment due to fear compared to dental students (P=0.004. “Heart beats faster” and “muscle being tensed” were the top two physiological responses experienced by the respondents. “Drill” and “anesthetic needle” were the most fear provoking objects among respondents of both faculties. Conclusion. Dental fear and anxiety are a common problem encountered among medical and dental undergraduates who represent future health care professionals. Also, high level of dental fear and anxiety leads to the avoidance of the dental services.

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

    Dental insurance status is strongly associated with service use. In models of dental visiting, insurance is typically included as an enabling factor. However, in Australia, people self-select into health insurance (privately purchased) and levels of cover for dental services are modest. Rather than enabling access, insurance status may be a "marker" for unmeasured predisposing attitudes. This study aims to explore associations between dental insurance status and visiting while adjusting for dental care attitudes. Participants (South Australians aged 45-54 years) of a 2-year prospective cohort study (2005-2007) investigating dental service use were surveyed on their attitudes to dental care and insurance status. Six attitudinal factors were assessed using a 23-item Likert scale. Bivariate associations between insurance, attitudes, visiting, and other known covariates (age, sex, and household income) were explored. A series of regression models assessed whether prevalence ratios of visiting were attenuated after controlling for attitudinal factors. Response rate was 85.0 percent. Analysis was limited to dentate adults with known dental insurance status (n=529). The majority had dental insurance (75.2%) and made regular visits (63.7%). Insurance status, visiting, and attitudinal factors were significantly associated. Controlling for covariates, insured adults, compared with the uninsured, were 57 percent more likely to make regular visits. After adjusting for attitudinal factors, the significant association between insurance and visiting persisted. Dental care attitudes did not confound the association between dental insurance and visiting, indicating that dental insurance status was not a "marker" for predisposing attitudes. © 2012 American Association of Public Health Dentistry.

    Full Text Available Dental bleaching is a simple and conservative procedure for aesthetic restoration of vital and non-vital discolored teeth. Nevertheless, a number of studies have demonstrated the risk of tissue damage from the contact of these agents with the oral mucosa. In the current study, the genotoxic potential associated with exposure to dental bleaching agents was assessed by the single cell gel (comet assay in vitro. Chinese hamster ovary (CHO cells in vitro were exposed to six commercial dental bleaching agents (Clarigel Gold - Dentsply; Whitespeed - Discus Dental; Nite White - Discus Dental; Magic Bleaching - Vigodent; Whiteness HP - FGM and Lase Peroxide - DMC. The results pointed out that all dental bleaching agents tested contributed to DNA damage as depicted by the mean tail moment, being the strongest effect observed with the highest dose of hydrogen peroxide (Whiteness HP and Lase Peroxide, at a 35% concentration. On the other hand, Magic Bleaching (Vigodent induced the lowest level of DNA breakage. Negative and positive controls displayed absence and presence of DNA-damaging, respectively. Taken together, these results suggest that dental bleaching agents may be a factor that increases the level of DNA damage. A higher concentration of hydrogen peroxide produced higher noxious activities in the genome as detected by single cell gel (comet assay.Clareamento dental é um procedimento simples e conservador para restaurar esteticamente a cor de dentes vitais e não-vitais.

    The dental team plays an integral role in safeguarding the general health of patients. Dental health care workers should be able to recognize risk factors associated with hypertension and counsel patients in an effort to reduce those that are present. In addition, dental professionals should recognize how these risk factors and associated hypertension affect the provision of dental care. This article reviews recent findings and therapies for hypertension, evaluates historically accepted but unsupported anecdotal information on the dental management of hypertensive patients and proposes guidelines for the dental management of these patients.

In 1977, there were only 59 Mexican dental schools; however, there were 83 schools registered in the last official national count in 2007. Forty-one dental schools are public, and the other 42 are private. Every year the number of private dental schools increases. Admission to dental schools in Mexico requires a high school diploma. All classes are conducted in Spanish. To obtain licensure in Mexico, dental students must complete a 3 to 5-year program plus a year of community service. No formal nationwide standard clinical/didactic curriculum exists in Mexico. There are approximately 153,000 dentists in Mexico, a number that increases each year. The dentist-patient ratio is approximately 1:700. However, the high percentage of inactive licensed dentists in Mexico points to a serious problem.

    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.

    2001-10-01

    Modern dental alloys have been used for 50 years to produce prosthetic dental restorations. Generally, the crowns and frames of a prosthesis are prepared in dental alloys, and then veneered by feldspar ceramics or composites. In use, the alloys are exposed to the corrosive influence of saliva and bacteria. Metallic dental materials can be classified as precious and non-precious alloys. Precious alloys consist of gold, platinum, and small amounts of non-precious components such as copper, tin, or zinc. The non-precious alloys are based on either nickel or cobalt, alloyed with chrome, molybdenum, manganese, etc. Titanium is used as Grade 2 quality for dental purposes. As well as the dental casting alloys, high purity electroplated gold (99.8 wt.-%) is used in dental technology. This review discusses the corrosion behavior of metallic dental materials with saliva in ''in vitro'' tests and the influence of alloy components on bacteria (Lactobacillus casei and Streptococcus mutans). The test results show that alloys with high gold content, cobalt-based alloys, titanium, and electroplated gold are suitable for use as dental materials. (orig.)

    Dental caries is one of the most common infectious diseases. Of the oral bacteria, mutans streptococci, such as Streptococcus mutans and S. sobrinus, are considered to be causative agents of dental caries in humans. There have been numerous studies of the immunology of mutans streptococci. To control dental caries, dental caries vaccines have been produced using various cell-surface antigens of these organisms. Progress in recombinant DNA technology and peptide synthesis has been applied to the development of recombinant and synthetic peptide vaccines to control dental caries. Significant protective effects against dental caries have been shown in experimental animals, such as mice, rats and monkeys, which have been subcutaneously, orally, or intranasally immunized with these antigens. Only a few studies, however, have examined the efficacy of dental caries vaccines in humans. Recently, local passive immunization using murine monoclonal antibodies, transgenic plant antibodies, egg-yolk antibodies, and bovine milk antibodies to antigens of mutans streptococci have been used to control the colonization of the organisms and the induction of dental caries in human. Such immunization procedures may be a safer approach for controlling human dental caries than active immunization.

    The aim of this study is to determine if there is any interaction between special colorant found on bleaching agents that have 35 % of hydrogen peroxide on its composition, and argon or diode laser. The first part of the study was to characterize the extrinsic stain obtained through a staining solution containing products present on the day by day diet of the general population. Thirty-two inferior human extracted incisors, free of caries and without filling material were selected for the study. The laser devices employed were Argon laser (AccuCure 3000 TM - Lasermed), wave length 488 nm, with a 200 mW/cm{sup 2} for 30 seconds in continuos mode; and diode laser (L 808 Medical Laser - Lasering do Brasil), wave length 808 {+-} 10 nm, with 1,6 W/cm{sup 2} for 30 seconds in continuos mode. The application mode done by a scanning movement over the buccal surface. The bleaching agents used were: Opalescence Extra (OE) - Ultradent Products USA, hydrogen peroxide 35%, gel with Carotene to convert light into heat; Pola Office (PO) - SDI - USA single doses of hydrogen peroxide; Whiteness HP (WHP) - FGM - Brasil, hydrogen peroxide 35%; Opus White (OW) - Sharplan - Israel, hydrogen peroxide 35%. The temperature rise measurement was performed with a thermocouple model 120-202-AJ, Fenwal, inserted into the pulpar chamber. The bleaching material was applied on the tooth surface with 2 mm thickness and then the irradiation was perform. The thirty two teeth were randomized in four groups, two for each laser device. The obtain data demonstrated a superior performance of the Argon laser on tooth whitening and also better results concerning the temperature rise. The alteration on tooth coloration was verified through digital spectrophotometer (Shade-Eye EX - Shofu) and quantitative analyses showed statistical differences among the groups. The bleaching results for Argon laser combined with OE and WHP were superior for the other groups. The mean variation of the temperature rise obtained Argon laser were {<=} 5,6 deg C, and the values obtained with the Diode laser were {>=} 5,6 deg C. The results obtained lead to conclude that Argon laser is safer and more efficient than diode laser for tooth whitening procedures, and the best results achieved with the association of Argon laser irradiation to the bleaching agent OP and WHP.

  2. The future dental workforce?

    2009-02-28

    The Editor-in-Chief of the BDJ has previously raised important questions about dental workforce planning and the implications for dental graduates of recent changes and pressures. It is now time to revisit this issue. Much has changed since the last workforce review in England and Wales, and the rate of change is in all probability set to increase. First, at the time of writing this paper the momentous step of including dental care professionals (DCPs) on General Dental Council (GDC) registers in the United Kingdom has recently been completed. Second, the Scope of Practice of all dental professionals has been under consultation by the General Dental Council, and research evidence suggests that greater use should be made of skill-mix in the dental team. Third, within England, Lord Darzi has just published the 'Final Report of the NHS Next Stage Review', which emphasises 'quality care' and 'team-working' as key features of healthcare; this report was accompanied by an important document entitled 'A High Quality Workforce', in which plans for local workforce planning within the NHS are outlined, placing responsibilities at national, local and regional levels. Fourth, policy makers across the UK are wrestling with addressing oral health needs, promoting health and facilitating access to dental care, all of which have implications for the nature and shape of the dental workforce. Fifth, with the impact of globalisation and European policies we are net gainers of dentists as well as having more in training. Sixth, although there have been reviews and policy initiatives by regulatory, professional and other bodies in support of shaping the dental workforce, there has been little serious consideration of skill-mix and funding mechanisms to encourage team-working. Together, these events demand that we enter a fresh debate on the future dental workforce which should extend beyond professional and national boundaries and inform workforce planning. This debate is of great

  6. What is dental ecology?

    Science.gov (United States)

    Cuozzo, Frank P; Sauther, Michelle L

    2012-06-01

    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. Copyright © 2012 Wiley Periodicals, Inc.

    Humphris, Gerry M; Freeman, Ruth

    2012-01-01

    Medline and the Social Science Index Citation databases were searched. Studies had to have used measures of dental anxiety completed by children themselves (≤16 years), been published in English and reported primary data. Non-validated measures, those using proxy measures and non-dentally specific measures were excluded. Data were extracted independently using a standardised form. Validity and reliability of the questionnaires were assessed, and measures were evaluated against a theoretical framework of dental anxiety. A qualitative summary of the measures is presented. Sixty studies met the inclusion criteria. These covered seven 'trait' and two 'state' measures of dental anxiety used to assess children's dental anxiety over the past decade. The findings from this systematic review can be used to help guide dental academics, clinicians, psychologists and epidemiologists to choose the most appropriate measure of dental anxiety for their intended use. Future work should involve evaluating the content and developmental validity of existing measures with further consideration given to the use of theoretical frameworks to develop this field.

    The reintroduction and development of safe motorized instruments, the increased availability of continuing education, and the understanding and implementation of appropriate procedures allow practitioners to provide better dental care. Veterinarians realize that sedation, analgesia, a full-mouth speculum, and proper instrumentation are necessary to provide these services. Continued instrument design, future research, and new treatment and prophylactic protocols should have a positive impact on the future of equine dental health. New and rediscovered procedures for equilibrating equine occlusion are allowing horses to masticate more efficiently, carry a bit more comfortably, and experience improved performance. The horse, the horse owner, and the veterinary profession all benefit from providing complete equine dental care.

    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.

    2012-10-01

    Full Text Available 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.

    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

    Fisher, Monica A; Beeson, Dennis C; Hans, Mark G

    2009-12-01

    As dental schools incorporate training in evidence-based dentistry (EBD) into their curricula, students must learn how to critically evaluate systematic reviews and meta-analyses. It is important that dental education in the United States support the American Dental Association's position statement on EBD, which defines "best evidence" as data obtained from all study designs. Given that much evidence is missing when EBD is derived from Cochrane Systematic Reviews' randomized clinical trials, we propose the creation of a dental practice network of U.S. dental schools. We developed an electronic clinical dentistry research database for EBD using Epi-Info (available at www.cdc.gov/epiinfo/downloads.htm). As a free, public use software, Epi-Info provides the foundation for the development of clinical research databases that can increase the research capacity through multisite studies designed to generate outcomes data on the effectiveness of dental treatment. The creation of a dental practice network of dental schools with their large number of patients would expand the research capacity for EBD practice and advance the EBD science regarding the effectiveness of dental treatment. The next step is to link clinical dental researchers/educators at multiple dental schools through a collaborative clinical research network, so that the findings can be applied to the EBD component of problem-based learning curricula of dental education.

    1997-01-01

    Bacteremia resulting from dental extraction is regarded as an important cause of bacterial endocarditis, and it is therefore recommended that patients undergoing tooth extraction be given prophylactic antibiotics. As dental procedures other than extractions may also cause bacteremias, we studied a variety of dental procedures routinely used in pediatric dentistry. Blood samples for cultures were obtained 30 s after each of 13 dental operative procedures in 735 anesthetized children aged 2-16 years. Four procedures used for conservative dentistry caused bacteremias significantly more often than the baseline value of 9.4%: polishing teeth 24.5%, intraligamental injection 96.6%, rubber dam placement 29.4%, and matrix band with wedge placement 32.1%. In comparison, toothbrushing alone caused a bacteremia on 38.5% of occasions. The organisms isolated were typical of odontogenic bacteremias in that 50% of the isolates were identified as varieties of viridans streptococci. These data show that a wider variety of dental procedures than was previously documented cause bacteremia.

    Dental pulp is a highly specialized mesenchymal tissue, which have a restrict regeneration capacity due to anatomical arrangement and post-mitotic nature of odontoblastic cells. Entire pulp amputation followed by pulp-space disinfection and filling with an artificial material cause loss of a significant amount of dentin leaving as life-lasting sequelae a non-vital and weakened tooth. However, regenerative endodontics is an emerging field of modern tissue engineering that demonstrated promising results using stem cells associated with scaffolds and responsive molecules. Thereby, this article will review the most recent endeavors to regenerate pulp tissue based on tissue engineering principles and providing insightful information to readers about the different aspects enrolled in tissue engineering. Here, we speculate that the search for the ideal combination of cells, scaffolds, and morphogenic factors for dental pulp tissue engineering may be extended over future years and result in significant advances in other areas of dental and craniofacial research. The finds collected in our review showed that we are now at a stage in which engineering a complex tissue, such as the dental pulp, is no longer an unachievable and the next decade will certainly be an exciting time for dental and craniofacial research.

    Diagnosis and treatment for traumatic dental injuries are very complex owing to the multiple trauma entities represented by six luxation types and nine fracture types affecting both the primary and the permanent dentition. When it is further considered that fracture and luxation injuries are often...... combined, the result is that more than 100 trauma scenarios exist, when the two dentitions are combined. Each of these trauma scenarios has a specific treatment demand and prospect for healing. With such a complexity in diagnosis and treatment, it is obvious that even experienced practitioners may have...... problems in selecting proper treatment for some of these trauma types. To remedy this situation, an Internet-based knowledge base consisting of 4000 dental trauma cases with long-term follow up is now available to the public and the professions on the Internet using the address http://www.DentalTrauma...

    During the last decades, people have tried to develop a better material for use in dental obturation materials. This new material should meet the following requirements: durability, wear resistance, biocompatibility and chemical adhesion to dentin enamel. Wear resistance is very important and it is related with the service life of dental replacements. We have obtained aesthetically promising novel nano composites that can be used as dental replacements. The main objective of this work is to study the scratch and wear resistance of these nano composites. To meet this goal, scratch tests are performed using a micro scratch tester machine (CSEM), where a diamond indenter is used to make the scratch and the penetration of this indenter is measured with high resolution (7nm). We will be looking at the penetration depth (Rp) and the residual (or healing) depth (Rh) to calculate the percent recovery. These measurements represent the scratch resistance of the material.

    A high number of patients have one or more missing tooth and it is estimated that one in four American subjects over the age of 74 have lost all their natural teeth. Many options exist to replace missing teeth but dental implants have become one of the most used biomaterial to replace one (or more) missing tooth over the last decades. Contemporary dental implants made with titanium have been proven safe and effective in large series of patients. This review considers the main historical facts concerned with dental implants and present the different critical factors that will ensure a good osseo-integration that will ensure a stable prosthesis anchorage.

    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.

    Approximately 50% of children under the age of 15 are victims of various kinds of injuries in the orofacial region. Post-traumatic complications may occur, including crown discolouration, cervical root fracture, ankylosis, root resorption and tooth loss. The most severe complication after dental injury in primary dentition can affect the developing permanent tooth germ, and various consequences may be seen several years later when the permanent tooth erupts. In the permanent dentition, the most severe dental injury affects the surrounding alveolar bone structure and will lead to loss of the tooth. Current literature emphasises that awareness of appropriate triage procedures following dental trauma is unsatisfactory and that delay in treatment is the single most influential factor affecting prognosis. What should a paediatrician know, and more importantly, how should he/she advise parents and caretakers? In an emergency situation such as tooth avulsion, reimplantation within 30 min is the best treatment option at the site of the accident. If reimplantation of the tooth is impossible, milk, saline or even saliva are the preferred transport media. The prognosis for an avulsed tooth depends upon prompt care, which is a determinant factor for successful treatment of the traumatised tooth. In all other dental trauma cases, it is important to refer the child to a paediatric dentist, to follow up the healing process and reduce late post-traumatic complications. With timely interventions and appropriate treatment, the prognosis for healing following most dental injuries is good. In conclusion, it is important that paediatricians are able to inform parents and caretakers about all possible and long-lasting consequences of different dental injuries.

    Dental anxiety can be a hindrance to treatment. It is prevalent, so helping patients to overcome it should not be regarded as the province of a specialist. Hypnosis can be effective but is underused. A comparison of the conscious, alert state and hypnosis/nitrous oxide sedation is shown by electroencephalogram examples. The benefits and drawbacks of the use of hypnosis are discussed and suggestions of ways of learning and using hypnosis outlined. This paper is an overview of the common problem of dental anxiety and a pragmatic approach to overcoming it using hypnotherapy.

    By all outward signs, the dental profession is prospering. However, signs of a looming crisis in dental education threaten the future effectiveness of the profession. Transforming dental education through the application of principles espoused by the ADEA Commission on Change and Innovation in Dental Education (CCI) is essential for securing the future of the profession. To meet the future oral health needs of the public, dental schools must retain their research mission and prepare students for evidence-based practice. To accomplish this, both the curricular content and the environment and approach to dental education must change. Besides the knowledge and abilities needed to care for a more diverse and aging population, future practitioners must possess tools needed to thrive in the world of small business and have the ethical foundation to conduct themselves as responsible professionals. Ensuring the future of the profession is a leadership challenge to be shared by both dental educators and practitioners.

    Full Text Available Dentist and dental nurse as dental health personnel in community health center are spearheads in community dental health service. The effectiveness and efficacy of community dental health service needs updated adequate dental health knowledge and skill. One effort to assure the fulfillment of those needs is by providing community dental health survey training. This training aims at improving the skill and capability of dental health personnel to conduct dental health survey. The training consisted of materials on community dental health survey, principles of survey implementation, and field survey activity as an integral part of the training. Survey was conducted among third grade students of Madrasah Ibtidaiyah (MI in Tangerang city. Targeting and sampling part of the survey was implemented by city health office. There were 224 students, 182 parents, and 16 teachers who were successfully examined and/or interviewed. The survey showed that the participant’s knowledge was significantly (p<0.05 improved. The survey also showed that only 34% of the students had good oral hygiene score. There were 46.9% of students who suffered M1 caries and 47.3% had caries on their permanent teeth. Parents’ knowledge and attitude regarding child dental health was quite good and teachers had implemented students dental care effort. In conclusion, the survey-training model was proved to be useful to refresh the community dental health science while simultaneously obtained important data through survey. This model had never been conducted before and new breakthrough in the community dental health science refreshing activity targeted to local dental health personnel.

    Full Text Available Background. In 1999, An Oral Health Survey of American Indian and Alaska Native (AI/AN Dental Patients found that 79% of 2- to 5-year-olds had a history of tooth decay. The Alaska Native Tribal Health Consortium in collaboration with Alaska’s Tribal Health Organizations (THO developed a new and diverse dental workforce model to address AI/AN oral health disparities. Objectives. This paper describes the workforce model and some experience to date of the Dental Health Aide (DHA Initiative that was introduced under the federally sanctioned Community Health Aide Program in Alaska. These new dental team members work with THO dentists and hygienists to provide education, prevention and basic restorative services in a culturally appropriate manner. Results. The DHA Initiative introduced 4 new dental provider types to Alaska: the Primary Dental Health Aide, the Expanded Function Dental Health Aide, the Dental Health Aide Hygienist and the Dental Health Aide Therapist. The scope of practice between the 4 different DHA providers varies vastly along with the required training and education requirements. DHAs are certified, not licensed, providers. Recertification occurs every 2 years and requires the completion of 24 hours of continuing education and continual competency evaluation. Conclusions. Dental Health Aides provide evidence-based prevention programs and dental care that improve access to oral health care and help address well-documented oral health disparities.

  15. Review of Spaceflight Dental Emergencies

    Menon, Anil

    2012-01-01

    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.

  16. Drugs that promote dental caries.

    Science.gov (United States)

    2015-02-01

    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.

    1994-07-01

    DM is such a common disease in the United States that virtually every dentist encounters patients with known or undiagnosed diabetes. The dentist should be alert for both general and oral signs and symptoms suggestive of uncontrolled or poorly controlled DM, and laboratory or interoffice screening tests should be a part of dental practice. Under no circumstances, however, should the dentist attempt to diagnose the disease. Patients with suggestive symptoms or with abnormal blood glucose levels identified by screening tests should be referred to a physician for diagnosis and any treatment necessary. Uncontrolled DM may be associated with increased frequency and severity of oral infections, including periodontal disease and dental caries. In some diabetic patients, susceptibility to oral disease may continue despite establishment of effective metabolic control. Dental treatment can safely be performed on the controlled diabetic patient, but some adjustment of office protocol and of antihyperglycemic drug administration may occasionally be necessary. Finally, the dental treatment team must always be alert for signs and symptoms of developing diabetic emergencies and be prepared to provide treatment as necessary.

    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.

    A workflow is defined as a predefined set of work steps and partial ordering of these steps in any environment to achieve the expected outcome. Few studies have investigated the workflow of providers in a dental office. It is important to understand the interaction of dental providers with the existing technologies at point of care to assess breakdown in the workflow which could contribute to better technology designs. The study objective was to assess electronic dental record (EDR) workflows using time and motion methodology in order to identify breakdowns and opportunities for process improvement. A time and motion methodology was used to study the human-computer interaction and workflow of dental providers with an EDR in four dental centers at a large healthcare organization. A data collection tool was developed to capture the workflow of dental providers and staff while they interacted with an EDR during initial, planned, and emergency patient visits, and at the front desk. Qualitative and quantitative analysis was conducted on the observational data. Breakdowns in workflow were identified while posting charges, viewing radiographs, e-prescribing, and interacting with patient scheduler. EDR interaction time was significantly different between dentists and dental assistants (6:20 min vs. 10:57 min, p = 0.013) and between dentists and dental hygienists (6:20 min vs. 9:36 min, p = 0.003). On average, a dentist spent far less time than dental assistants and dental hygienists in data recording within the EDR.

    Using cigarettes and alternative tobacco products (ATPs) is associated with negative oral health outcomes, and dental health professionals are poised to help patients quit. The aim of this study was to determine dental, dental hygiene, and advanced dental students' use, knowledge, and beliefs about cigarettes and ATPs, including perceptions about their education in tobacco dependence treatment and counseling experience. All 1,783 students enrolled in the dental, dental hygiene, and postdoctoral dental programs at the New York University College of Dentistry were invited to participate in the survey in 2016. A total of 708 students at least partially completed the survey, for a response rate of 39.7%. In the results, 146 of the students (20.1%) reported ever using cigarettes, while 253 (35.7%) reported ever using any ATP. Regarding tobacco use intervention, the students reported they had not received enough training on ATPs, were neutral about cigarettes, and were somewhat confident and not so confident counseling a cigarette smoker or ATP user, respectively. By their fourth year, 77.8% of the dental students reported they had counseled someone to stop smoking cigarettes, but only 40.7% had counseled someone to stop using ATPs. Overall, all groups of students reported feeling more confident and had received more education on interventions for cigarettes than for ATPs (pcigarettes and ATPs. These findings call for a revised tobacco education curriculum for dental, dental hygiene, and advanced dental students, focused on building knowledge and confidence for promoting tobacco dependence treatment.

    There is growing evidence to support the contention that interprofessional education (IPE) at both pre and post-qualification levels will improve professionals' abilities to work more effectively in a team and to communicate more effectively with colleagues and patients. This body of evidence, however, is primarily concerned with nursing, medical and associated professionals and students, and there are few studies that include dental students and particularly where learning occurs with the dental care professions (DCP). The purpose of this study was to examine the attitudes of dental and DCP students to IPE and to highlight some of the barriers to developing programmes for these students. It was also intended to examine the students' awareness of dental and DCP roles and responsibilities. Two questionnaires, the Readiness for Interprofessional Learning Scale (RIPLS) and a dental roles and responsibilities questionnaire, were distributed to all 5 years of dental students (n = 189) based at Queen's University Belfast (QUB), both years of the dental hygiene students (n = 8) also based at QUB, as well as to final year dental nursing students based at Belfast Institute of Further and Higher Education (BIFHE) (n = 64). The results indicated that dental and DCP students had a positive attitude to IPE as a means to improve teamwork and communication skills but there are potential obstacles as demonstrated by the differing perceptions of each of the three groups about the roles of the other. Some aspects of practice, involving personal care and advice to patients, were regarded by all groups as a shared role but the dental hygiene students regarded themselves as having a shared role in several tasks identified by dental and dental nurse students as the sole role of the dentist. Dental hygiene students in this study did not see their role as primarily to support the dentist but more as a partner in care. Professional identity and its development are issues that must be

    The curriculum for graduating dental and dental hygiene students must prepare them to contribute to the improvement or maintenance of health for individual patient's and the public's health. The objective is to describe the background for and the process used to develop a core Dental Public Health Curriculum for such students. The process used was to solicit and review existing dental public health curriculum in dental and dental hygiene schools; review curriculum for other health professionals; identify the themes needed to frame the curriculum; select usable materials and identify gaps in existing curricular materials; and develop appropriate curriculum materials that would embody the competencies developed for undergraduate dental and dental hygiene education. Twenty-three topics were identified as embodying the eight competencies. Based on these topics, six courses, Principles of Dental Public Health, Evidence-Based Dentistry, Ethics and Dental Public Health, Dental Public Health Policy and Advocacy, Oral Health Promotion and Disease Prevention, and Oral Health Literacy and Dental Public Health, were prepared. Each course includes syllabus, PowerPoint presentations, student assignments and activities, instructor guide, and classroom discussion points. Depending on the hours available in the existing curriculum at the dental or hygiene school, lecture presentations and take home assignments/discussions may be used independently or in combination with presentations from other courses. In addition, individual discussions and activities may be used to integrate dental public health materials into other courses. A flexible curriculum is available at the AAPHD website to enable the incorporation of DPH topics into the curriculum. © 2015 American Association of Public Health Dentistry.

    Attitudes of dental students regarding the provision of treatment tend to be dentist-centered; however, facilitating mixed student group formation could change such perceptions. The aim of this study was to investigate the perceived scope of practice of dental and dental hygiene students and whether their perceptions of task distribution between dentists and dental hygienists would change following an educational intervention consisting of feedback, intergroup comparison, and competition between mixed-group teams. The study employed a pretest-posttest single group design. Third-year dental students and second-year dental hygiene students at a university in The Netherlands were randomly assigned to intraprofessional teams (four or five members) and received team-based performance feedback and comparison. The intervention was finalized with an award ceremony for the best intraprofessional team. Before and after the intervention, students completed a questionnaire measuring their perceived distribution of ten tasks between dentists and dental hygienists. A total of 38 dental students and 32 dental hygiene students participated in the intervention-all 70 of those eligible. Questionnaires were completed by a total 88.4% (n=61) of the participants: 34 dental (89.5%) and 27 dental hygiene students (84.4%). Dental and dental hygiene students had similar perceptions regarding teeth cleaning (prophylaxis) (p=0.372, p=0.404) and, after the intervention, preventive tasks (p=0.078). Following the intervention, dental students considered four out of ten tasks as less dentist-centered: radiograph for periodontal diagnosis (p=0.003), local anesthesia (p=0.037), teeth cleaning (p=0.037), and periodontal treatment (p=0.045). Dental hygiene students perceived one task as being less dentist-centered after the intervention: radiograph for cariologic diagnosis (p=0.041). This study found that these dental and dental hygiene students had different opinions regarding the scope of practice

    2011-09-01

    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.

    The aim of this study was to analyse dental care utilization, refrainment from self-perceived needed dental care and the association with socioeconomic indicators among adult individuals. This cross-sectional survey included 3500 randomly selected adult individuals. Telephone interviews were conducted and the participants answered a battery of questions regarding dental visiting habits, health, socioeconomic position (SEP), behavioural factors and lifestyle indicators. The outcome 'dental visits' was significantly correlated with SEP, especially with monetary dimensions, such as income and economic resources for unforeseen expenditures. However, educational level was not a significant predictor in the tested statistical models. Furthermore, other covariates that contributed significantly to the models were ethnicity, dental anxiety and lifestyle factors, albeit with a different pattern of impact on the two outcome dimensions. Important features of the SEP variables were the stepwise gradient relative to the outcomes, implicating that the lower the SEP status, the greater the risk of reporting irregular dental visiting habits and refraining from dental care due to financial problems. Dental care utilization and refraining from dental care for financial reasons clearly reveal associations with socioeconomic positions among adult individuals.

    Dental traumas are frequent in children. They can be complex events and sometimes real emergencies. Since very little attention is devoted to this topic in the international literature and there are no well-coded laser guidelines for these specific clinical events, our aim is to consider and present those situations in which laser-assisted therapy can offer new treatment possibilities. The authors' aim is to stimulate more extensive scientific research in this area, which might not only increase the use of these technologies, but also improve outcomes and reduce complications connected to dental trauma, particularly in children. Furthermore, laser-assisted therapies drastically reduce the need for analgesics and anti- inflammatory medications compared with conventional procedures. Using laser equipment to obtain anaesthesia is another challenge, while the use of low power setting for desensitising tissue and to obtain anaesthesia is also an open field.

    The long-term clinical success of dental implants is related to their early osseointegration. This paper reviews the different steps of the interactions between biological fluids, cells, tissues, and surfaces of implants. Immediately following implantation, implants are in contact with proteins and platelets from blood. The differentiation of mesenchymal stem cells will then condition the peri-implant tissue healing. Direct bone-to-implant contact is desired for a biomechanical anchoring of i...

    Self-reported dental anxiety in relation to sociocultural and socioeconomic variables were investigated in a random sample of the Norwegian population aged 15 years and older (n = 1351). Education, profession, number of years in school, family income and personal income were negligibly or not at all associated with dental anxiety. The only statistically significant difference in levels of self-reported dental anxiety in relation to social background factors was between female labourers (high level) and female functionaries (low level).

  7. Confronting shibboleths of dental education.

    Science.gov (United States)

    Masella, Richard S

    2005-10-01

    Shibboleths are common expressions presented as indisputable truths. When used in educational discussions, they reflect "motherhood and apple pie" viewpoints and tend to bring debate to a halt. Use of shibboleths may precede a desired imposition of "locksteps" in educational programming and are easily perceived as paternalistic by recipients. Nine shibboleths are presented as common beliefs of dental faculty and administrators. Evidence contradicting the veracity of the "obvious truths" is offered. The traditional "splendid isolation" of dentistry contributes to parochialism and belief in false shibboleths. Sound principles of higher and health professions education, student learning, and dental practice apply to dental education as to all health disciplines. Student passivity in dental education is not the best preparation for proficiency in dental practice. The master teacher possesses a repertoire of methodologies specific to meeting defined educational objectives. Active learning experiences bear close resemblances to professional duties and responsibilities and internally motivate future doctors of dental medicine. The difficulty in achieving curricular change leads to curricular entrenchment. Dentistry and dental education should not trade their ethical high ground for the relatively low ethical standards of the business world. Principles of professional ethics should govern relationships between dentists, whether within the dental school workplace or in practice. Suggestions are made on how to confront shibboleths in dental school settings.

    Serious medical emergencies are fortunately a rare occurrence in the dental practice environment; however, if an emergency situation is encountered a delay in treatment may result in potentially avoidable consequences. The risk of mortality or serious morbidity can be reduced by ensuring that basic emergency equipment and medications are in place, and that the dental team is appropriately trained in basic life support measures. This article aims to provide an overview of the basic emergency medications and equipment that should be present in dental practices, and to discuss specific responses to some of the more common adverse medical events that can present while providing dental treatment.

    Dental anxiety is common among children. Although there is a wealth of research investigating childhood dental anxiety, little consideration has been given to the child's perspective. This qualitative study sought to explore with children their own experiences of dental anxiety using a cognitive behavioural therapy assessment model. Face-to-face, semi-structured interviews were conducted with dentally anxious children aged 11-16 years. The Five Areas model was used to inform the topic guide and analysis. Data were analysed using a framework approach. In total, 13 children were interviewed. Participants described their experiences of dental anxiety across multiple dimensions (situational factors and altered thoughts, feelings, physical symptoms, and behaviours). Participants placed considerable value on communication by dental professionals, with poor communication having a negative influence on dental anxiety and the dentist-patient relationship. This study confirms the Five Areas model as an applicable theoretical model for the assessment of childhood dental anxiety. Children provided insights about their own dental anxiety experiences that have not previously been described. © 2016 BSPD, IAPD and John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    2004-11-01

    Dental anxiety and subsequent avoidance of dental care and deterioration of oral health pose a significant problem for the dental profession. In an attempt to elucidate preferences of anxious dental patients, we gathered survey data from 121 persons at a small, private liberal arts college in the mid-Atlantic region of the United States. Half of the respondents experienced dental anxiety, and most of these (66 percent) attributed anxiety to fear of anticipated pain. The majority of anxious patients preferred a dentist to be friendly (93 percent), talkative (82 percent), and to have an office with adorned walls (89 percent) and a slightly cool temperature (63 percent). Patients who identified themselves as anxious also indicated that music in the background (89 percent) and magazines and books in the dental office (75 percent) were helpful. Anxious patients were more likely than non-anxious patients to prefer a male dentist (77 percent versus 52 percent). This finding was especially marked among anxious male respondents, 93 percent of whom preferred a male dentist compared to 73 percent of anxious female respondents. These survey data may assist dental professionals in understanding and combating patients' dental anxiety, in order to increase the frequency of dental visits and to prompt a corresponding restoration or maintenance of oral health.

  11. Cognitive vulnerability and dental fear

    Directory of Open Access Journals (Sweden)

    2008-01-01

    Full Text Available Abstract Background The Cognitive Vulnerability Model proposes that perceptions of certain characteristics of a situation are critical determinants of fear. Although the model is applicable to all animal, natural environment and situational fears, it has not yet been applied specifically to dental fear. This study therefore aimed to examine the association between dental fear and perceptions of dental visits as uncontrollable, unpredictable and dangerous. Methods The study used a clustered, stratified national sample of Australians aged 15 years and over. All participants were asked in a telephone interview survey to indicate their level of dental fear. Participants who received an oral examination were subsequently provided with a self-complete questionnaire in which they rated their perceptions of uncontrollability, unpredictability and dangerousness associated with dental visiting. Results 3937 participants were recruited. Each of the three vulnerability-related perceptions was strongly associated with the prevalence of high dental fear. In a logistic regression analysis, uncontrollability and dangerousness perceptions were significantly associated with high dental fear after controlling for age and sex. However, unpredictability perceptions did not have a statistically significant independent association with dental fear after controlling for all other variables. Conclusion Results are mostly consistent with the Cognitive Vulnerability Model of the etiology of fear, with perceptions of uncontrollability, unpredictability and dangerousness each showing a strong bivariate relationship with high dental fear prevalence. However, more extensive measures of vulnerability perceptions would be valuable in future investigations.

    Dental satisfaction is associated with continuity of dental care, compliance with dentist advice, and positive health outcomes. It is expected that people with higher dental fear might have less dental satisfaction because of more negative dental experiences. The objective of this study was to examine satisfaction and reasons for satisfaction with dental practitioners in Switzerland and variations by dental fear. A national sample of 1,129 Swiss residents aged 15-74 (mean = 43.2 years) completed a personal interview at their home with questions assessing dental fear, dental service use, general satisfaction with their dentist, and reasons for satisfaction or dissatisfaction. Overall, 47.9 percent of participants responded that they were satisfied with their dentist and 47.6 percent that they were very satisfied. Satisfaction differed significantly by gender, language spoken, region of residence, and educational attainment. Greater dental fear was significantly associated with greater dissatisfaction with the dentist. The percentage of people who were very satisfied with the dentist ranged from 56.0 percent among people with no fear to 30.5 percent for participants with "quite a lot" of fear but was higher (44.4 percent) for people who stated that they were "very much" afraid of the dentist. The most common reasons attributed for satisfaction with dentists were interpersonal characteristics of the dentist and staff. People with "quite a lot" of fear were found to endorse these sentiments least. Although higher dental fear was associated with more dissatisfaction with the dentist, the level of satisfaction among fearful individuals in Switzerland is still high. © 2012 American Association of Public Health Dentistry.

    Osteoradionecrosis (ORN) is a severe complication of radiation therapy (RT). A triggering factor is frequently present. It is often a dental, periodental, or surgical traumatism. We report the case of a bilateral ORN: the first lesion appeared 3months after the end of RT around the osteosynthesis plate and was treated by mandibular resection. The second lesion appeared 40months after RT on the opposite side, due to peri-implantitis. Dental implants had been inserted 10years before cancer therapy. No case of ORN in post-implantation RT had been previously reported. A 75-year-old woman was admitted for a squamous cell carcinoma of the right cheek extending to the intermaxillary commissure, the maxillary tuberosity, the soft palate, the lingual junction, and the vestibule up to the second premolar area. There was no suspicious lymph node. She had undergone dental implant procedure 15 and 10 years before, respectively, one in the second premolar position of the right maxilla and four in the premolar and molar left mandible area. All of them were osseo-integrated and charged. A trans-mandibular buccopharyngectomy with modified radical neck dissection was performed, completed by RT. The total dose of irradiation was 65Gy in the oral cavity and 45Gy on cervical and supraclavicular areas. Delayed mucosal healing was observed on the right mandible and ORN appeared in this area 3months after the end of irradiation. Mandibular resection was necessary. Later, the right maxillary implant was lost, and multiple dental extractions were required. Forty months after RT, peri-implantitis was observed on the left side of the mandible, complicated by ORN and pathological fracture. No surgical reconstruction could be performed because of the patient's age and state. The patient was carrying a complete removable maxillary prosthesis on latest follow-up. This was the first case of ORN on dental implants placed before RT. RT is a risk factor of implant failure, a relatively rare and

    2016-11-25

    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. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    This study evaluated the presence of current and general phobia and anxiety symptoms in periodontology patients just before treatment in relation to specific dental fears and to general health status and quality of life. The study population was all consecutive outpatients attending the Periodontics and Implantology Services, School of Dentistry, University of Bologna, over a 12-month period in 2007. Data collection instruments were psychological questionnaires (State-Trait Anxiety Inventory [STAI]-Y1, Marks-Sheehan Phobia Scale [MSPS], World Health Organization Quality of Life [WHOQOL] short form) plus supplementary items investigating specific dental fears, patient's dental history, and the dentist's clinical assessment of the patient. In all, 250 consecutive patients were recruited. Most (86%) presented with very mild anxiety and phobia symptoms; 13.2% and 13% presented with psychological symptoms of anxiety and phobia, respectively, independently of those subjects with specific dental fears who were significantly younger. The most common dental fears were fear of pain (48.8%) and of receiving an injection (29.9%). The patients' quality of life did not appear to be affected by these fears. In the dental outpatients seeking treatment for moderate-to-severe dental pathology at a university periodontics and implantology clinic and referring good general health and psychosocial functioning, levels of anxiety and phobia were usually low or absent; but when present, they were independent of ascertained specific dental fears.

    Teeth are colonized by oral bacteria from saliva containing more than 700 different bacterial species. If removed regularly, the dental biofilm mainly comprises oral streptococci and is regarded as resident microflora. But if left undisturbed, a complex biofilm containing up to 100 bacterial species at a site will build up and may eventually cause development of disease. Depending on local ecological factors, the composition of the dental biofilm may vary considerably. With access to excess carbohydrates, the dental biofilm will be dominated by mainly gram-positive carbohydrate-fermenting bacteria causing demineralization of teeth, dental caries, which may further lead to inflammation and necrosis in the pulp and periapical region, i.e., pulpitis and periapical periodontitis. In supra- and subgingival biofilms, predominantly gram-negative, anaerobic proteolytic bacteria will colonize and cause gingival inflammation and breakdown of supporting periodontal fibers and bone and ultimately tooth loss, i.e., gingivitis, chronic or aggressive periodontitis, and around dental implants, peri-implantitis. Furthermore, bacteria from the dental biofilm may spread to other parts of the body by bacteremia and cause systemic disease. Basically, prevention and treatment of dental biofilm infections are achieved by regular personal and professional removal of the dental biofilm. © 2017 APMIS. Published by John Wiley & Sons Ltd.

  10. Dental Forensics: Bitemark Analysis

    Directory of Open Access Journals (Sweden)

    Elza Ibrahim Auerkari

    2013-06-01

    Full Text Available Forensic odontology (dental forensics can provide useful evidence in both criminal and civil cases, and therefore remains a part of the wider discipline of forensic science. As an example from the toolbox of forensic odontology, the practice and experience on bitemark analysis is reviewed here in brief. The principle of using visible bitemarks in crime victims or in other objects as evidence is fundamentally based on the observation that the detailed pattern of dental imprints tend to be practically unique for each individual. Therefore, finding such an imprint as a bitemark can bear a strong testimony that it was produced by the individual that has the matching dental pattern. However, the comparison of the observed bitemark and the suspected set of teeth will necessarily require human interpretation, and this is not infallible. Both technical challenges in the bitemarks and human errors in the interpretation are possible. To minimise such errors and to maximise the value of bitemark analysis, dedicated procedures and protocols have been developed, and the personnel taking care of the analysis need to be properly trained. In principle the action within the discipline should be conducted as in evidence-based dentristy, i.e. accepted procedures should have known error rates. Because of the involvement of human interpretation, even personal performance statistics may be required from legal expert statements. The requirements have been introduced largely due to cases where false convictions based on bitemark analysishave been overturned after DNA analysis.DOI: 10.14693/jdi.v15i2.76

    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.

    In this study on aggression in the dental practice, 8 dentists and 1 dental nurse who had experienced aggression in their dental practice, were interviewed and filled out a questionnaire. They had responded to a call in 2 Dutch dental journals or were contacted through personal communication. The interviews show that aggression in particular can be expected in patients having not paid their expense account, non compliant patients, or in patients who often come too late or even do not show up at their appointments. Aggression also can appear when patients with toothache are told they cannot be helped immediately. Aggression seems predominantly connected to people under influence of alcohol or drugs, psychiatric patients and people having contacts in criminal circuits. Although the incidence seems relatively low, the occurrence of aggression always has a great impact on the dental team. Therefore it seems useful to study how dentists and their auxiliaries could act to prevent aggression.

    Dental practice is the integral component of the oral health. Though the dental practice is in close relation with that of the medical practice, it has its own distinctiveness in relation to safe practice. The safe dental practice should not only assure good oral and general health but also improve social interaction by enhancing physical appearance, esthetics, etc. For the safe dental practice, dentists must excel in patient care and standard of treatment. The interlocking missions of education, research, and patient care are the cornerstones for the safe and healthy dental practice. This paper is designed to bridge the gap between the educational preparation of the dentist and the reality of the working world in a simple way.

  17. Are dental students ready for supercomplex dental practice?

    Leadbeatter, D; Peck, C

    2018-02-01

    Contemporary dental practice requires practitioners who are able to draw upon varying interconnected knowledge and skills, in order to make judgments and take action when faced with multiple, often contradictory, ways of interpreting a situation. However, the curricula that prepare students for dental practice are traditionally based on the theoretical knowledge and technical skills to be gained by students. This is despite evidence in the dental literature of a collective desire for graduates to have more range and depth in their repertoire. Examination of contemporary dental practice through the lens of supercomplexity (Higher Education, 40, 409 and 2000) provides contextual understanding and a platform to explore the types of learning and curriculum approaches that can best prepare students for professional practice. From the insights offered by examples from other professional fields, we, as dental educators, can begin to conceptualise learning dentistry as much more than competency frameworks or descriptions of what students need to know and be able to do. Rather, to equip graduates for contemporary dental practice, the dental curriculum needs to become a vehicle for students to develop personally and professionally as well as teaching the theoretical and technical aspects of dentistry. © 2017 John Wiley & Sons A/S.

    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.

    Bernson, Jenny M; Elfström, Magnus L; Hakeberg, Magnus

    2013-06-01

    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. © 2013 Eur J Oral Sci.

    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.

    2008-01-01

    Recent negative publicity has drawn attention away from recognizing and celebrating the ways today's dental students differ in a positive fashion from previous generations of dental students who may have suffered the same ethical lapses we are hearing about now. Dental students are more diverse than their predecessors and learn to develop a sense of integrity that encompasses more toleration of alternative cultures. They are group-oriented, which expresses itself in sharing responsibility for their colleagues, both in educational settings and in their practices. With guidance from senior dentists and organized dentistry, they will contribute inclusiveness and group responsibility and thus strengthen the profession.

  12. Entrepreneurship in continuing dental education: a dental school perspective.

    2005-01-01

    The definition of continuing dental education is presented, along with its benefits to the profession. The preeminence of dental schools in providing lifelong learning opportunities and freedom from commercial involvement that existed even twenty years ago has changed. Less than a quarter of CE takes place in school, and the focus there is increasingly on material with deep scientific background and hands-on learning. The newest innovations and those with the greatest commercial potential are taught elsewhere. Proposed changes in the ADA CERP standards would take on a "purist" approach that could place dental schools at a severe disadvantage while allowing "for profit" institutes to flourish and thus further undermine the role dental schools can play in providing quality professional development experiences.

    2011-01-01

    Head and neck cancer is a real presence in the dental-implant world--patients who undergo surgery, chemotherapy, and/or radiation often seek the assistance of dental-implant practitioners to restore them to better function; other patients who have had implants in place for years will return with questions regarding how their treatment will be affected by the presence of their dental implant. As oral-cancer treatment modalities are rapidly changing, practitioners struggle to keep up with the literature surrounding this important subset of the dental-implant population. This month, we look at the numbers of patients suffering from oral cancers, consider the different treatment options for patients with oral cancers, and investigate the role that implants play in improving therapeutic outcomes or changing treatment course.

    Harr, R

    2001-01-01

    Society now expects more from its doctors and dentists, and these increasing demands can be summed up in one relatively new term for the medical profession: "quality management" (QM). Doctors and dentists formerly took the view that their performance could be assessed solely on the basis of their technical skills, ethics and expertise, but are now confronted with a new social imperative, from outside the profession--quality management. The author, prize-winner of the European Quality Award 2000 describes his approach to introduce the European Foundation for Quality Management (EFQM) Excellence Model in his dental practice. He shows that the EFQM model is well suited as a basis for a quality management system in healthcare.

    2015-05-01

    Full Text Available All treatment involving the use of biomaterials in the body can affect the host in positive or negative ways. The microbiological environment in the oral cavity is affected by the composition and shape of the biomaterials used for oral restorations. This may impair the patients’ oral health and sometimes their general health as well. Many factors determine the composition of the microbiota and the formation of biofilm in relation to biomaterials such as, surface roughness, surface energy and chemical composition, This paper aims to give an overview of the scientific literature regarding the association between the chemical, mechanical and physical properties of dental biomaterials and oral biofilm formation, with emphasis on current research and future perspectives.

    To estimate responsibility loadings for a comprehensive list of dental services, providing a standardized unit of clinical work effort. Dentists (n = 2500) randomly sampled from the Australian Dental Association membership (2011) were randomly assigned to one of 25 panels. Panels were surveyed by questionnaires eliciting responsibility loadings for eight common dental services (core items) and approximately 12 other items unique to that questionnaire. In total, loadings were elicited for 299 items listed in the Australian Dental Schedule 9th Edition. Data were weighted to reflect the age and sex distribution of the workforce. To assess reliability, regression models assessed differences in core item loadings by panel assignment. Estimated loadings were described by reporting the median and mean. Response rate was 37%. Panel composition did not vary by practitioner characteristics. Core item loadings did not vary by panel assignment. Oral surgery and endodontic service areas had the highest proportion (91%) of services with median loadings ≥1.5, followed by prosthodontics (78%), periodontics (76%), orthodontics (63%), restorative (62%) and diagnostic services (31%). Preventive services had median loadings ≤1.25. Dental responsibility loadings estimated by this study can be applied in the development of relative value scales. © 2017 Australian Dental Association.

    2013-01-01

    Full Text Available 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.

    Full Text Available 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.

    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.

    The people of Appalachia-West Virginia are culturally unique and are known to have oral health disparities. The purpose of this study was to evaluate dental fear in relation to delayed dental care as a factor influencing oral health behaviors within this culture. A cross sectional study design was used. Participants were urgent care patients in a university dental clinic. The sample included 140 adults over age 18 years. The Dental Fear Survey was used to determine dental fear level. Self-report of delayed dental care was provided by the participants. The Dental Fear Survey was dichotomized at score 33, with higher scores indicating dental fear. The prevalence of dental fear was 47.1% (n=66). There was a significant association of dental fear and dental delay. The unadjusted odds ratio was 2.87 (95% CI: 1.17, 7.04; p=0.021). The adjusted odds ratio was 3.83 (95%CI: 1.14, 12.82; p=0.030), controlling for tobacco use, perceived oral health status, pain, and last dental visit. A difference in dental delay between men and women was not present in this sample. The only significant variable in delayed dental care was dental fear. In Appalachia-West Virginia, there remains a high level of dental fear, despite advances in dental care, techniques, and procedures. Copyright © 2015 The American Dental Hygienists’ Association.

    This paper explores the thesis that the changing medical needs of dental patients, advances in biomedical research, and the confluence of the financing of medical and dental care will result in closer linkages between the medical and dental care delivery systems during the next century. Five trends have been documented in support of this thesis: the increasing number of elderly and their retention of teeth means there is a greater need for restorative dental care than in previous generations; the elderly have chronic diseases and are taking more medications; younger patients are presenting more frequently with infectious, systemic diseases such as HIV/AIDS. New scientific discoveries are opening new possibilities for patient care, which generate even higher expectations on the part of future consumers of medical and dental services. The health and fitness trend is not a fad; new knowledge regarding diet, nutrition, and exercise is identifying systemic risk factors related to common oral pathologies. Medical and dental educators are paying increased attention to the application of basic sciences to patient care. HMOs are increasing their market share of medical care delivery and expanding their services with preventive care and total patient care, including dental services. Data are provided documenting that dentists see these trends occurring in their private practices. The paper concludes that the application of advances in science and technology to oral health will improve the quality of dentistry. However, only new, effective preventive agents will decrease the cost of care, while improved diagnostics and restorative technologies could increase dental care costs.(ABSTRACT TRUNCATED AT 250 WORDS)

    Measuring dental clinic service quality is the first and most important factor in improving care. The quality provided plays an important role in patient satisfaction. The purpose of this paper is to identify factors affecting dental service quality from the patients' viewpoint. This cross-sectional, descriptive-analytical study was conducted in a dental clinic in Tehran between January and June 2014. A sample of 385 patients was selected from two work shifts using stratified sampling proportional to size and simple random sampling methods. The data were collected, a self-administered questionnaire designed for the purpose of the study, based on the Parasuraman and Zeithaml's model of service quality which consisted of two parts: the patients' demographic characteristics and a 30-item questionnaire to measure the five dimensions of the service quality. The collected data were analysed using SPSS 21.0 and Amos 18.0 through some descriptive statistics such as mean, standard deviation, as well as analytical methods, including confirmatory factor. Results showed that the correlation coefficients for all dimensions were higher than 0.5. In this model, assurance (regression weight=0.99) and tangibility (regression weight=0.86) had, respectively, the highest and lowest effects on dental service quality. The Parasuraman and Zeithaml's model is suitable to measure quality in dental services. The variables related to dental services quality have been made according to the model. This is a pioneering study that uses Parasuraman and Zeithaml's model and CFA in a dental setting. This study provides useful insights and guidance for dental service quality assurance.

    There have been recent changes in teenage lifestyle and diet. The increasing consumption of soft drinks and foods containing significant acidic components may play a role in the development of dental erosion. The aims of this investigation were firstly to assess the prevalence of vegetarian children in a cluster random sample of 14-year-old children in Birmingham, United Kingdom. Secondly, to determine the prevalence of dental erosion in these children, and thirdly, to see if there were any differences between vegetarian and non-vegetarian children in the prevalence of dental erosion and dietary intake. A cluster random sample of 418 14-year-old children (209 males and 209 females) were examined from 12 different schools in Birmingham, United Kingdom; a dietary questionnaire was completed and the levels of tooth wear were recorded using a modification of the (TWI) index. All data were analysed using SPSS with t-test and Chi-square analysis. Significance was accepted at the P children were vegetarian; 52% of them had low dental erosion and 48% moderate dental erosion. Statistically there were no significant differences between vegetarian and non-vegetarian children in the prevalence of erosion; however, there were significant differences in some food and drink consumption. It was concluded that dental erosion is common in teenage children, but there were no significant differences in prevalence between vegetarian and non-vegetarian children.

    The paradigmatic shift to evidence-based dentistry (EBD) that relates to occlusal therapy, selective occlusal adjustment (OA) and stabilization splints therapy (SS) for TMDs has had an unfavourable impact on the teaching of many of the important aspects of occlusion needed in dental practice. The teaching of OA systematically in dental schools has been nearly abandoned because of the belief that OA is an irreversible procedure and gives the impression that it is without merit elsewhere in the management of occlusion. However, a particular dose of knowledge and practice of occlusion that is necessary for all aspects of dental care should be taught systematically in dental schools. The uses and misuses of OA and SS and their limitations should be emphasized because of their importance to bring clinical reality into the dental curriculum. Thus, and irrespective of EBD induced contradictions, OA and SS should still have a significant place in systematically teaching of occlusal therapy. However, there are many more aspects of the management of occlusion that should to be considered. Hopefully, because of their importance, other aspects of the management of occlusion will once again become a significant part of the dental curriculum.

    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.

    Dental treatment is usually performed without any development of medical sequela. However, patients can acquire serious, life threatening complications, even though successful dental treatment is completed. This paper presents four case reports of medical complications following routine pediatric dental treatment. The cases include: Ludwig's angina, endocarditis, brain abscess, and anesthetic toxicity. Many of the medical complications were caused by pre-existing conditions and were not necessarily direct result of dental treatment. Although medical complications following dental treatment cause grave concern, the dental practitioner can learn much from these occurrences.

    To assess the frequency and causes of dental anxiety and their relation to irregular dental visits among adult dental patients. The Dental Anxiety Question (DAQ) included within a self-administered questionnaire was distributed to 1025 patients attending the Interns' Dental Clinics in the Department of Preventive Dental Sciences, College of Dentistry, University of Dammam, Dammam, Kingdom of Saudi Arabia from March 2012 to February 2013. A cross-sectional study design was used. The questionnaire consisted of 22 closed-ended questions divided into 4 sections; 1) demographics, 2) regularity of dental visits, and related causes, 3) DAQ, cancellation of dental appointments, history of previous trauma, dental anxiety provoking factors within dental environment and procedures, and 4) patients' status in dental clinics, preferences of dentists, and perceptions regarding dental anxiety. The prevalence of dental anxiety among the study sample was 27%. Anesthetic injection was the main factor of dental fear (88.2%), while dental surgical procedures (35.7%) and extractions (23%) were the most terrifying dental procedures. Lack of time (79.5%), cost (71.5%), far-situated dental services (62.2%), and fear (57.1%) were causes listed for irregular dental visits; while 31.3% had no specific reason. Irregular dental visits were not related to dental anxiety. Dental anxiety continues to be an obstacle despite the vast improvement in dentistry; and this raises an alert regarding personal and communication factors in the patient-dentist relationship. Factors such as equal distribution of dental services, time, and cost should also be addressed.

    Full Text Available The aim of the present study was to evaluate the association between childhood dental experiences and dental fear in adulthood among dentistry, psychology and mathematics undergraduate students. A cross-sectional study of 1,256 students from the city of Belo Horizonte, Brazil, was performed. Students responded to the Brazilian version of the Dental Fear Survey (DFS and a questionnaire regarding previous dental experiences. Both the DFS and the questionnaire were self-administered. Association was tested using descriptive, bivariate and multivariate linear regression analysis, with a 5% significance level. Dentistry undergraduates reported lower scores than psychology (p < 0.001 and mathematics undergraduates (p < 0.05 for all three dimensions of the DFS. Negative dental experiences in childhood was associated with dimensions of Avoidance (B = 2.70, p < 0.001, Physiological arousal (B = 1.42, p < 0.001 and Fears of specific stimuli/situations (B = 3.44, p < 0.001. The reason for first visit to dentist was associated with dimensions of Physiological arousal (B = 0.76, p < 0.01 and Fears of specific stimuli/situations (B = 1.29, p < 0.01. Dentists should be encouraged to evaluate the dental fear of their patients before treatment. The DFS has been found to be an effective instrument for this purpose.

    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.

    Full Text Available Periodontal disease is among the most prevalent canine dis-eases affecting over 75% of dogs. Strengthening of the human-animal bond and the increasing education of the aver-age pet owner, have fostered a heightened awareness of periodontal care in dogs and cats. Industry support has further assisted the small animal veterinarian in providing quality dental treatments and prevention. As recently as the 1990’s, veterinary curriculums contained little or no dental training. That trend is changing as nearly every one of the 28 US Colleges of Veterinary Medicine offers some level of small animal dentistry during the four-year curriculum. Primary areas of focus are on client education, the treatment of periodontal disease, dental prophylaxis, dental radiology, endodontics, exodontics and pain control. Students receive instruction in dental anatomy during their di-dactic curriculum and later experience clinical cases. Graduate DVMs can attend a variety of continuing education courses and even choose to specialize in veterinary dentistry in both small animals and horses. Through the efforts of organizations such as the American Veterinary Dental So-ciety, The American Veterinary Dental College and The Academy of Veterinary Dentistry, many veterinarians have been able to advance their skills in dentistry and improve animal welfare. Increasing ex-pectations of the pet-owning public coupled with the recent advancements of training opportunities available for vete-rinary students, graduate DVMs and certified veterinary technicians make veterinary dentistry an emerging practice-builder among the most successful small animal hospitals.

    The objectives of this article are to describe the dental assistant's role in the dental delivery system; assess the educational structure of the dental assisting profession; and project factors likely to impact the future role of the dental assistant. The article summarizes the current status and trends of the dental assisting profession including general responsibilities, credentialing, and regulation. An overview of the workforce and parameters of employment is provided with a description of the broad scope of practice, education, and licensure options, which vary by state. Existing academic models and enrollment trends in accredited dental programs are included, as are the strengths and weaknesses of the current educational system. Multiple factors may impact the future of this profession. To address the anticipated increase in the demand for and responsibilities of dental assistants, curricular revisions will be needed to prepare for implementation of interprofessional care models in which dental assistants will play a vital role. Well-educated dental assistants will be needed to support viable models of dental care and wellness in the U.S. Enhanced career opportunities and varied employment environments may increase job satisfaction and practice longevity. As protection of the public is of the utmost importance in the dental profession, this evolving dental clinician must be formally educated in all aspects of clinical practice and be permitted to perform delegated patient care, as legally allowed by their states. This article was written as part of the project "Advancing Dental Education in the 21st Century."

  12. Periostin in dental science

    Full Text Available In this mini-review, we focus on periostin, a matricellular protein that is preferentially expressed in cells such as fibroblastic cells in the periodontal ligament (PDL and osteoblastic cells on the alveolar bone surfaces. Since the abnormal phenotypes of periostin-deficient mice in periodontal tissues have been reported over the last 5 years, we would like to summarize the action of this protein in the PDL, including our unpublished results. Following these results, we hypothesize the function of periostin in the PDL: (1 activation of matrix metalloproteinases for collagen remodeling, and (2 stabilization of the Notch1 protein for anti-apoptotic signaling against stress conditions through the secretion pathway from the inside to outside of the PDL cells. Furthermore, recent observations have demonstrated that periostin functions in fibrillogenesis in association with extracellular matrix molecules. Finally, for clinical applications of periostin, several translational research studies have started in respiratory and cardiovascular medicine. Such research will stimulate the study of dental application of this protein for the treatment of periodontal diseases.

    Full Text Available In the present study we aimed to optimize the thermal imaging method for evaluation of skin patch test reactions in dental clinical allergology. A total of 30 patients without a history of allergic diseases were included in the study - 12 men and 18 women, age 21 - 32 years. Skin patch testing was performed with a set of 20 standardized allergens. The thermographic investigations were performed with the FlirT620 infrared camera with a temperature resolution of 0,06°C. Thermograms were analysed using the Flir Reporter Professional software 2013. The statistical analysis of the results revealed an average correlation between the clinical evaluation of the results according to the cheme of ICDRG and the thermal image diagnostic (rphi = 0.538, p = 0.001. Absolute matching of clinical and thermal image results was observed only for the negative ones. For the clinically positive skin patch results matching with thermal image method was observed in 60.7% of the cases. Optimization of thermal imaging as a method for evaluation of skin patch test results could serve as a safe, accurate and non-invasive method, especially to distinguish weak (+, doubtful and irritant reactions, although not standardized criteria to distinguish these reactions have been elaborated yet. Crucial factor for the accurate interpretation of results is the precise diagnosing performed by well-trained physicians in this area, with clinical relevance, to minimize the role of subjective factors.

    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.

    To check knowledge of undergraduate dental students to make diagnosis of dental fluorosis with varying degrees of severity and choose its appropriate treatment. Data were collected using a semi-structured questionnaire addressing knowledge of undergraduates based on ten images of mouths presenting enamel changes. Only three images were correctly diagnosed by most undergraduates; the major difficulty was in establishing dental fluorosis severity degree. 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.

    Full Text Available Dental anxiety is associated with previous distressing dental experiences, such as lack of understanding of the dentist intentions, perceptions of uncontrollability and experiences of pain during dental treatment. People with autism spectrum disorder (ASD are impaired in building flexible predictions and expectations, which is very much needed during a dental visit. The aims of the study were to investigate if people with ASD have more negative dental experiences and a higher level of dental anxiety compared to a matched control group. Forty-seven adults with ASD and of normal intellectual performance, and 69 age- and sex-matched typically developing controls completed questionnaires on previous dental experiences and dental anxiety, the Dental Anxiety Scale, and the Dental Beliefs Survey. The ASD group experienced pain during dental treatments more often than the controls and 22% had repeatedly experienced being forced to dental treatment they were not prepared for, compared to 3% of the controls. A higher level of dental anxiety was reported by the ASD group. Dental treatment and methods for supporting the communication with patients with ASD need to be developed, in order to reduce the negative dental experiences and dental anxiety in people with ASD.

    While somatization has been investigated as an important variable in relation to excessive health-service utilization, its role in relation to dental visiting and dental fear has received limited attention. It was hypothesized that an excessive focus on physical symptoms might lead somatizers to experience dental treatment as more traumatic, resulting in greater dental fear. The aims of this study were to determine whether somatization was associated with dental fear, reduced dental visiting, and symptomatic visiting. Questionnaire data were collected from 5,806 dentate Finnish adults, with somatization measured using 12 items from the Symptom Check List (SCL-90). Dental fear was measured using a single-item question and dental visiting was assessed by questions relating to time since last dental visit and the usual reason for dental visiting. Multinomial logistic regression analyses indicated that somatization has a statistically significant positive association with both dental fear and symptomatic dental visiting after controlling for age, gender, and education. However, the association between dental-visiting frequency and somatization was not statistically significant. The results were consistent with the hypothesized role of somatization in the development of dental fear. Further investigation of how somatization is related to dental fear and dental-service utilization appears warranted. © 2011 Eur J Oral Sci.

    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.

    The purpose of this study was to assess the incidence of traumatic dental injury among Turkish children and young adults with autism and compare this to the general population of Turkish children and young adults without autism. This study was comprised of 186 children and young adults (138 males and 48 females), 93 with autism (autistic group, or AG) and 93 without autism (control group, or CG). Dental injuries were classified according to drawings and texts based on the WHO classification system, as modified by Andreasen and Andreasen. The rate of injury was higher among the AG (23%) than the CG (15%). The difference between the 2 groups, however, was not statistically significant (Pdental injury was enamel fracture. The rate of enamel fracture was higher in the CG (59%) than in the AG (33%), and the distribution of types of traumatic injury differed significantly between the AG and CG (P>.01). There were no significant differences in the rates of traumatic dental injuries among children and young adults with and without autistic disorder. The most frequently injured teeth were the permanent maxillary central incisors, and the frequency of injury to these teeth differed significantly (P>.01) between AG (56%) and CG (91%). The most common type of dental injury, enamel fracture, was more common in CG (59%) than AG (33%). The distribution of types of traumatic dental injuries differed significantly between the 2 groups (P>.01).

  4. Dental surgery in ancient Egypt.

    2013-01-01

    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.

    Soft dental tissues have been identified as easily accessible sources of multipotent postnatal stem cells. Dental stem cells are mesenchymal stem cells (MSC) capable of differentiating into at least three distinct cell lineages: osteo/odontogenic, adipogenic and neurogenic. They express various markers including those specific for MSC, embryonic stem cells and neural cells. Five different types of dental stem cells have been isolated from mature and immature teeth: dental pulp stem cells, stem cells from exfoliated deciduous teeth, periodontal ligament stem cells, stem cells from apical papilla and dental follicle progenitor cells. Dental stem cells may be used in dental tissue engineering including dental, enamel and periodontal tissue regeneration.

    2010-06-01

    Full Text Available Nowadays there are many methods available for dental age estimation: morphological, radiological, biochemical. Some methods require sample sectioning while other non-destructive methods are more appropriate for use in paleodontology. Children’s dental age assessment is based on phases in growth and development of the deciduous and permanent dentition, while age assessment in the adult dentition is based upon changes in the structure of hard dental tissue caused by aging. Dental age calculating software enables automated age calculations.

    This case report reviews the variability of dental eruption and the possible sequelae. Dental eruption of the permanent teeth in cleft palate children may be variable, with delayed eruption the most common phenomenon. A case of premature dental eruption of a maxillary left first premolar is demonstrated, however, in a five-year-old male. This localized premature dental eruption anomaly was attributed to early extraction of the primary dentition, due to caries.

    This study investigated the dental health of children (aged 1-14 years) diagnosed with cancer 4-36 months earlier. Sixty patients were examined and interviewed; 43% had untreated decay and only 35% had seen a dentist since their malignancy had been diagnosed. A significant source of bacterial infection is not being treated in this at risk population. The level of dental disease and lack of dental prevention indicates a need to integrate medical and dental care.

    Feng, Xue; Sambamoorthi, Usha; Wiener, R Constance

    2017-04-01

    There is considerable variation in dental services utilization across Appalachian counties, and a plausible explanation is that individuals in some geographical areas do not utilize dental care due to dental workforce shortage. We conducted an ecological study on dental workforce availability and dental services utilization in Appalachia. We derived county-level (n = 364) data on demographic and socioeconomic characteristics and dental services utilization in Appalachia from the 2010 Behavioral Risk Factor Surveillance System (BRFSS) using person-level data. We obtained county-level dental workforce availability and physician-to-population ratio estimates from Area Health Resources File and linked them to the county-level BRFSS data. The dependent variable was the proportion using dental services within the last year in each county (ranging from 16.6% to 91.0%). We described the association between dental workforce availability and dental services utilization using ordinary least squares regression and spatial regression techniques. Spatial analyses consisted of bivariate local indicators of spatial association (LISA) and geographically weighted regression (GWR). Bivariate LISA showed that counties in the central and southern Appalachian regions had significant (P dental workforce availability, low percent dental services utilization). GWR revealed considerable local variations in the association between dental utilization and dental workforce availability. In the multivariate GWR models, 8.5% (t-statistics > 1.96) and 13.45% (t-statistics > 1.96) of counties showed positive and statistically significant relationships between the dental services utilization and workforce availability of dentists and dental hygienists, respectively. Dental workforce availability was associated with dental services utilization in the Appalachian region; however, this association was not statistically significant in all counties. The findings suggest that program and policy efforts to

  1. The estimation of need for dental care.

    Science.gov (United States)

    Spencer, A J

    1980-01-01

    This paper presents a background discussion of the estimation of normative need for dental care. Definitions are given which differentiate normative need for dental care from perceived need, demand, or utilization. Four different approaches to obtaining estimates of normative need for dental care are outlined. They are the translation of data from surveys of dental status, surveys of need for dental care, analyses of service or treatment records, and best judgment of dental practitioners. Present limitations within the four aproaches to estimating need to include factors such as objectivity, directness, completeness, precision, and extent of population coverage. Applications of estimates of need for dental care are identified in the areas of evaluation, setting of priorities, and planning of dental health programs. Current developments in the area of health services, including the concepts of an adequate minimum standard for personal health services, quality assurance, and rationing by need, are seen as providing some impetus for greater interest in need for dental care. Future directions in the estimation of dental needs will depend upon the validation of the approaches outlined, as well as general factors including costs of collecting data on dental status and need for dental care in population.

    2013-01-01

    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.

    2014-03-01

    Ceramics are used for many dental applications and are characterized in various ways, including by their hardness, brittleness, thermal and electrical insulation, and biocompatibility. The ceramics most commonly used in dentistry are oxides, particularly silicon dioxide (SiO2), or silica; aluminum oxide (Al2O3), or alumina; and zirconium dioxide (ZrO2), or zirconia. This article reviews the microstructure of current dental ceramic materials and how it relates to their mechanical properties, clinical techniques, and optical properties. Typical ceramics currently in use are described, and their clinically relevant properties such as strength, fracture, polishability, and wear are compared. Cementation methods are also discussed.

    2013-01-01

    Tooth loss or absence is a common condition that can be caused by various pathological circumstances. The replacement of the missing tooth is important for medical and aesthetic reasons. Recently, scientists focus on tooth tissue engineering, as a potential treatment, beyond the existing prosthetic methods. Tooth engineering is a promising new therapeutic approach that seeks to replace the missing tooth with a bioengineered one or to restore the damaged dental tissue. Its main tool is the stem cells that are seeded on the surface of biomaterials (scaffolds), in order to create a biocomplex. Several populations of mesenchymal stem cells are found in the tooth. These different cell types are categorized according to their location in the tooth and they demonstrate slightly different features. It appears that the dental stem cells isolated from the dental pulp and the periodontal ligament are the most powerful cells for tooth engineering. Additional research needs to be performed in order to address the problem of finding a suitable source of epithelial stem cells, which are important for the regeneration of the enamel. Nevertheless, the results of the existing studies are encouraging and strongly support the belief that tooth engineering can offer hope to people suffering from dental problems or tooth loss.

    Endosseous implants have revolutionized dental prosthetic rehabilitation, providing a reliable, a stable, and an aesthetic option for dental reconstruction. Dental implants have similarly improved the functionality of reconstructions following cancer surgery. The use of dental implants in oral cancer reconstruction can be divided into 2 categories: (1), for retention of a prosthetic device, for example, palatal obturator, used as the primary means of maxillary reconstruction, and (2), for dental rehabilitation after bony reconstruction of the jaws. This article discusses these different uses of endosseous implants in patients with head and neck cancer. Copyright © 2011 Elsevier Inc. All rights reserved.

    2005-03-01

    Information on dental caries among patients attending Mulago Hospital is scarce. Yet knowledge of the pattern of caries can be used to plan preventive and treatment interventions. This study describes the pattern of dental caries (in terms of age group, tooth and tooth surface and gender) among patients attending the Public Health Dental Officers School Clinic, Mulago Hospital. A review of patients' treatment records for the period 1995 to 1999 was done. A total of 1800 cards were reviewed for the diagnosis of dental caries, age, gender and the data was analyzed using EPI INFO 6 program. The patients were from both urban and peri-urban settings and were aged between 10-90 years. The results showed that the most frequently affected tooth surface was the occlusal (68.8%) followed by the interproximal (24%) and the least affected was the lingual/palatal (1.5%). The second molars were found to be the most affected of all teeth, with tooth 37(12%), 47(11%), 17(9.5%) and 27 (9.1%). The distribution of caries was higher in the lower than the upper jaw. There was a slight difference in sex predilection with females having 54.5% and males 45.5% of the lesions and the age group most affected was 20-29 years. The results showed a high occurrence of occlusal surface caries in molars especially the second molars in the 20-29 age group in the patients attending the Public Health Dental Officers School Clinic, Mulago Hospital.

    2014-08-20

    Poor or inequitable access to oral health care is commonly reported in high-, middle- and low-income countries. Although the severity of these problems varies, a lack of supply of dentists and their uneven distribution are important factors. Delegating care to dental auxiliaries could ease this problem, extend services to where they are unavailable and liberate time for dentists to do more complex work. Before such an approach can be advocated, it is important to know the relative effectiveness of dental auxiliaries and dentists. To assess the effectiveness, costs and cost effectiveness of dental auxiliaries in providing care traditionally provided by dentists. We searched the following electronic databases from their inception dates up to November 2013: the Cochrane Effective Practice and Organisation of Care (EPOC) Group's Specialised Register; Cochrane Oral Health Group's Specialised Register; the Cochrane Central Register of Controlled Trials (Issue 11, 2013); MEDLINE; EMBASE; CINAHL; Cochrane Database of Systematic Reviews; Database of Abstracts of Reviews of Effectiveness; five other databases and two trial registries. We also undertook a grey literature search and searched the reference list of included studies and contacted authors of relevant papers. We included randomised controlled trials (RCTs), non-randomised controlled clinical trials (NRCTs), interrupted time series (ITSs) and controlled before and after studies (CBAs) evaluating the effectiveness of dental auxiliaries compared with dentists in undertaking clinical tasks traditionally performed by a dentist. Three review authors independently applied eligibility criteria, extracted data and assessed the risk of bias of each included study and two review authors assessed the quality of the evidence from the included studies, according to The Cochrane Collaboration's procedures. Since meta-analysis was not possible, we gave a narrative description of the results. We identified five studies (one cluster

    This study was designed to identify personal, familial, academic, and employment characteristics of dental hygiene students from the central region of the United States to develop a comprehensive student profile for research and recruitment purposes. In fall 1990, 25 dental hygiene program directors in ten states in the central region of the United States and 475 students enrolled in these programs were mailed surveys to develop program and student profiles. Data were analyzed using measures of central tendency and frequency. Directors and students from 24 of 25 dental hygiene programs responded. Data are reported from these 24 directors and 422 of 464 (91%) of the students enrolled in the programs. Dental hygiene students in the central region of the United States are similar in personal, parental, and academic backgrounds to the general population of college students nationally. Unlike the general college population, the regional dental hygiene population tends to be singularly female. Students chose to major in dental hygiene for economic and personal reasons. The availability of employment opportunities, the flexibility to work full- or part-time, and the prospects of making a better income and becoming a professional influenced their decision. Students identified dentists, dental hygienists, and relatives as being influential in their becoming interested in the dental hygiene profession. Previous dental office employment experience also influenced many students in their career choice. The study findings provide information for dental hygiene educators and others interested in student characteristics and factors that influence the selection of dental hygiene as a career.

  1. Dental Problems in Calcium Metabolism Disorders

    Ali Rabbani M.D.

    2011-06-01

    Full Text Available Background: Calcium metabolism disorders can be acute or chronic and chronic disorders can cause different disease states such as dental problems. Methods: In this descriptive cross-sectional study done in Children's Medical Center affiliated to Tehran University of Medical Sciences during 2005-2009, all (93 patients with hypoparathyroidism, nutritional rickets, hypophosphatemic rickets and renal osteodysthrophy from the endocrinology and nephrology departments of the Center were referred to a dentist there for orodental examination. Subsequently, the frequency of dental problems including taurodontism, enamel hypoplasia, dental abscess, dental caries and gingivitis were recorded and analyzed. Results: Nutritional rickets was the most common disorder in this study and delay in dentition was the most frequent dental problem in the patients (61.9%. Most cases of taurdontism and enamel hypoplasia were seen in patients with hypoparathyroidism (33% and 50%, respectively. Dental abscess, dental caries and gingivitis were more common in patients with renal osteodysthrophia (50%, 90% and 20%, respectively. In addition, dental caries and delay in dentition were the most prevalent disorders in this study (69.8% and 49.5%, respectively. Conclusion: According to the above findings, it seems that effective screening, regular periodic examinations, proper diagnosis and timely treatment of dental diseases are the main principles of prevention of orodental problems. Moreover, dentists as well as pediatricians should be aware of the features of the aforesaid disorders which lead to dental problems so that early intervention could prevent subsequent serious and more invasive dental problems.

    Dental hygiene activities were developed as part of a randomized clinical trial designed to assess the safety of low-level mercury exposure from dental amalgam restorations. Along with dental-hygiene clinical work, a community programme was implemented after investigators noticed the poor oral hygiene habits of participants, and the need for urgent action to minimize oral health problems in the study population. Clinical and community activity goal was to promote oral health and prevent new disease. Community activities involved participants and their fellow students and were aimed at providing education on oral health in a school environment. Dental hygienists developed clinical work with prophylaxis, sealants application and topical fluoride and implemented the community programme with in-class sessions on oral health themes. Twice a month fluoride mouthrinses and bi-annual tooth brushing instructional activity took place. Participation at dental-hygiene activities, sealed teeth with no need of restoration and dental-plaque-index were measures used to evaluate success of the programme for the participants. Improvement in dental hygiene is shown by the decrease in dental plaque index scores (P teeth. 888 (13.7%) teeth with sealants had to be restored or were lost. Children participated actively on dental hygiene activities. Teachers became aware of the problem and included oral-health in school curricula. Dental hygiene activities have shown to be helpful to promote dental hygiene, promote oral health and to provide school-age children with education on habits that will be important for their future good health.

    To investigate caregivers' preference regarding dental stories to prepare children with autism for dental visits. Caregivers of children with autism were allowed use of dental stories available via different media (paper, tablet computer, computer) and image types (comics or drawings, photographs, video). Caregivers completed pre- and postintervention surveys. Fisher's exact tests were used to determine associations between predictive factors and preferences. Forty initial and 16 follow-up surveys were completed. Subjects were primarily male (85%). Mean child age was 6.7 years. Nine (64%) caregivers found the dental story useful for themselves and their child. Two (14%) caregivers found the aid only helpful for themselves. Preferred media type was associated with language understanding (p = .038) and home media preference (p = .002). Practitioners should consider using dental stories to help prepare families and children for dental visits. Individual preferences for dental stories vary; using prior history can aid in selection. © 2016 Special Care Dentistry Association and Wiley Periodicals, Inc.

    To determine the attitudes of general dental practitioners toward aspects of change in undergraduate dental education. Descriptive postal survey using a cross-sectional random sample of general dental practitioners administered in 1997. 689 general dental practitioners practising in five regions of England with close proximity to a dental school selected by a one in two stratified random sample. Response rate: 70%. The questionnaire was both valid and reliable with an internal consistency reliability coefficient of 0.84. Responses identified strong support for preparing dental students for the wider role of the dentist and an emphasis toward self-directed learning. Other themes emerging from the investigation included support for learning to work as part of a dental team and for students to have experience of general dental practice early on in the undergraduate course. These responses have implications for curriculum design, syllabus, teaching methods, resources and staff development for dental schools in the UK.

    1994-01-01

    Several studies indicate that stress is inherently present in dental practice. The present study was conducted to help identify the factors underlying this stress and the relative contribution of each factor. A questionnaire presented participating dentists with 52 potentially-stressful situations related to dental practice. Respondents were asked to rate each situation on a five-point scale, using a range of responses that varied from "not stressful" to "exceedingly stressful," and "I don't know" to "not applicable." The present data are based on the ratings given by the 1,332 dentists practicing in Québec who answered the questionnaire (52 per cent). Ten situations received a mean score of greater than 3.0, and were therefore considered as above average stress-producing situations. The majority of these situations could be classified as being related either to dental procedures and office organization or to interpersonal relationships involving patients and/or office personnel. It was found that the older age groups showed significantly less stress for six of the 10 most stressful situations. This study has indicated the specific situations that most frequently lead to stress in dentists. The precise identification of these situations could lead to reduced stress through the elimination of its vague and insidious character. Furthermore, an understanding of the most common stress-causing situations allows the practitioner to take preventive measures to eliminate its damaging effects in the dental practice.

    This study was conducted to assess and increase the level of awareness of occupational hazards among the dental surgeons of Indian Navy. The data was obtained using a self-administrated questionnaire from 17 serving dental surgeons that included questions on personal data, awareness of occupational hazards, safety measures practiced and experience of occupational hazard while in practice. All the respondents were aware of the occupational hazards at workplace and had been vaccinated against Hepatitis B infection. 82.3% had regular exposure to dental amalgam. Backache was the commonest hazard in 70.59% members of the study. This study shows that although there appears to be a high level of awareness of exposure to occupational hazards among the dental surgeons of the Indian Navy, the practical steps to prevent them needs to be reinforced. Increased awareness must be created about the dangers of chronic mercury poisoning, its prevention, the importance of regular monitoring of blood mercury levels and the mercury vapour levels in the clinic.

    2010-03-01

    Full Text Available Abstract Background Microbial denitrification is not considered important in human-associated microbial communities. Accordingly, metabolic investigations of the microbial biofilm communities of human dental plaque have focused on aerobic respiration and acid fermentation of carbohydrates, even though it is known that the oral habitat is constantly exposed to nitrate (NO3- concentrations in the millimolar range and that dental plaque houses bacteria that can reduce this NO3- to nitrite (NO2-. Results We show that dental plaque mediates denitrification of NO3- to nitric oxide (NO, nitrous oxide (N2O, and dinitrogen (N2 using microsensor measurements, 15N isotopic labelling and molecular detection of denitrification genes. In vivo N2O accumulation rates in the mouth depended on the presence of dental plaque and on salivary NO3- concentrations. NO and N2O production by denitrification occurred under aerobic conditions and was regulated by plaque pH. Conclusions Increases of NO concentrations were in the range of effective concentrations for NO signalling to human host cells and, thus, may locally affect blood flow, signalling between nerves and inflammatory processes in the gum. This is specifically significant for the understanding of periodontal diseases, where NO has been shown to play a key role, but where gingival cells are believed to be the only source of NO. More generally, this study establishes denitrification by human-associated microbial communities as a significant metabolic pathway which, due to concurrent NO formation, provides a basis for symbiotic interactions.

    Data sourcesMedline, Scopus and Google Scholar.Study selectionTwo reviewers selected studies independently. English language clinical studies assessing the association between temporomandibular disorders (TMD) and features of dental occlusion were considered.Data extraction and synthesisStudy quality was assessed based on the Newcastle-Ottawa Scale (NOS) and a narrative synthesis was presented.ResultsIn all 25 studies (17 case-control, eight comparative) were included. Overall there was a high variability between occlusal features and TMD diagnosis. Findings were consistent with a lack of clinically relevant association between TMD and dental occlusion. Only two studies were associated with TMD in the majority (≥50%) of single variable analyses in patient populations. Only mediotrusive interferences are associated with TMD in the majority of multiple variable analyses.ConclusionsThe findings support the absence of a disease-specific association, there is no ground to hypothesise a major role for dental occlusion in the pathophysiology of TMDs. Dental clinicians are thus encouraged to move forward and abandon the old-fashioned gnathological paradig.

    The prevalence and correlates of dental fear have been studied in representative population studies, but not in patients presenting for dental treatment. We hypothesized that dental fear among patients presenting at a large, urban college of dentistry would be similar to that of the population (e.g. 11% high dental fear, 17% to 35% moderate or higher fear) and that fear would be associated with avoidance of routine dental care, increased use of urgent dental care and poor oral health. Participants were 1070 consecutive patients at a large, urban dental care center. All patients completed a clinical interview, including demographics, medical history, dental history and presenting concerns, and behavioral health history. Patients were also asked to rate their dental anxiety/fear on a 1 (none) to 10 (high) scale. Over 20% of patients reported elevated anxiety/fear, of which 12.30% reported moderate and 8.75% high fear. Severity of dental anxiety/fear was strongly related to the likelihood of avoiding dental services in the past and related to myriad presenting problems. As hypothesized, the prevalence of moderate or higher fear in dental patients was considerable and closely matched that found in general population surveys. Thus, the 'dental home' is an ideal location to treat clinically significant dental anxiety/fear.

    2012-01-01

    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. © 2011 American Academy of Forensic Sciences.

    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.

    Full Text Available Globalization including General Agreement on Trade in Services (GATS and Asia Fair Trade Agreement (AFTA are a new free trade system. In globalization era, there will be an intense and free competition in looking for jobs throughout the world. This new system will affect the health services system in which health services tend to follow an industrial model. Meaning that dentistry or dental health services tend to be part of a business system, and this system has caused controversy among the community and the profession itself. The results of the discussion revealed that professional and business of dentistry is compatible and complementary. The tendency of increasing number of legal form of practice (group and a professional corporation and the worldwide advertisement of these practices supported the premise that delivering dental practice tends to follow the industrial model. Dentists should not only more focus on achieving financial success in running the business of practice but profession should have the most concern for the people who seek their services. Delivering quality of dental care depends on the high skill of the dentist and on the satisfactory income for the survival of the practice in the long run, and this make the practice will be viewed by the public and profession as being appropriate and of high quality. Facing the globalization, besides possessing high clinical skill, dentists must have a firm understanding of management concepts and apply them in their practice. In conclusion: The profession and the business of dentistry are compatible and complementary. The delivery of the dental services tends to follow the industrial model, which is a current reality. Dentist should concern more on the delivering high quality of dental services, not only focus on the business of the practice, although the satisfactory income is important for the survival growth of the practice in the long run. It is suggested for dentists to follow as

    This cross-sectional study was performed in the Dental School of Prince of Songkla University to ascertain noise exposure of dentists, dental assistants, and laboratory technicians. A noise spectral analysis was taken to illustrate the spectra of dental devices. A noise evaluation was performed to measure the noise level at dental clinics and one dental laboratory from May to December 2010. Noise spectral data of dental devices were taken during dental practices at the dental services clinic and at the dental laboratory. A noise dosimeter was set following the Occupational Safety and Health Administration criteria and then attached to the subjects' collar to record personal noise dose exposure during working periods. The peaks of the noise spectrum of dental instruments were at 1,000, 4,000, and 8,000 Hz which depended on the type of instrument. The differences in working areas and job positions had an influence on the level of noise exposure (p personal hearing zone found that the laboratory technicians were exposed to the highest impulsive noise levels (137.1 dBC). The dentists and dental assistants who worked at a pedodontic clinic had the highest percent noise dose (4.60 ± 3.59%). In the working areas, the 8-hour time-weighted average of noise levels ranged between 49.7-58.1 dBA while the noisiest working area was the dental laboratory. Dental personnel are exposed to noise intensities lower than occupational exposure limits. Therefore, these dental personnel may not experience a noise-induced hearing loss.

  1. Salivary biomarkers for dental caries.

    As a highly prevalent multifactorial disease, dental caries afflicts a large proportion of the world's population. As teeth are constantly bathed in saliva, the constituents and properties of this oral fluid play an essential role in the occurrence and progression of dental caries. Various inorganic (water and electrolytes) and organic (proteins and peptides) components may protect teeth from dental caries. This occurs via several functions, such as clearance of food debris and sugar, aggregation and elimination of microorganisms, buffering actions to neutralize acid, maintaining supersaturation with respect to tooth mineral, participation in formation of the acquired pellicle and antimicrobial defense. Modest evidence is available on the associations between dental caries and several salivary parameters, including flow rate, buffering capacity and abundance of mutans streptococci. Despite some controversial findings, the main body of the literature supports an elevated caries prevalence and/or incidence among people with a pathologically low saliva flow rate, compromised buffering capacity and early colonization or high titer of mutans streptococci in saliva. The evidence remains weak and/or inconsistent on the association between dental caries and other saliva parameters, such as other possible cariogenic species (Lactobacillus spp., Streptococcus sanguis group, Streptococcus salivarius, Actinomyces spp. and Candida albicans), diversity of saliva microbiomes, inorganic and organic constituents (electrolytes, immunoglobulins, other proteins and peptides) and some functional properties (sugar clearance rate, etc.). The complex interactions between salivary components and functions suggest that saliva has to be considered in its entirety to account for its total effects on teeth. © 2015 John Wiley & Sons A/S.

    Objective The natural accumulation of supragingival plaque on surfaces of human teeth is associated with gingival inflammation and the initiation of common oral diseases. This study evaluated the distribution of dental plaque and gingivitis scores within the dental arches after prophylaxis. Methods Adult subjects from the Dharwad, India area representing the general population who provided written informed consent were scheduled for screening. Healthy subjects over the age of 18 years, not currently requiring any medical or dental care, and presenting with a complement of at least 20 natural teeth were recruited for this parallel design study. Enrolled subjects (n = 41) underwent oral examinations for dental plaque (PI) and gingivitis (GI) using the Turesky modification of the Quigley-Hein and the Löe-Silness Index, respectively, at the baseline visit, followed by a whole mouth dental prophylaxis. Subjects were given fluoride toothpaste for twice daily oral hygiene for the next 30 days. Subjects were recalled on days 15 and 30 for PI and GI examinations identical to baseline. Results Analyses indicated that mean scores for PI and GI on either arch and the whole mouth were higher than 2 and 1, respectively, during all examinations. Anterior surfaces consistently exhibited lower PI scores than posterior regions of either arch, or the entire dentition. Regional GI differences within the dentition were similar to PI scores, with lower scores on anterior than posterior teeth. Prophylaxis reduced both the frequency and mean scores of both PI and GI, irrespective of arch, with lower scores observed on anterior than posterior regions during all recall visits. Molar and lingual regions consistently exhibited higher PI and GI scores compared with anterior surfaces. At all examinations, mean scores for both plaque and gingivitis were higher on approximal vestibular than mid-vestibular surfaces. Conclusions Differences observed in PI and GI within the dentition have

    The teaching of dental English for undergraduate students plays an important role in dental education. Most dental schools or colleges have set up the course of dental English education in China. However, this course lacks of a unified educational plans, contents and goals based on actual situation of dental students, which does not fully achieve the teaching purpose. This study was aimed to explore the developmental direction of the course of dental English education through comparison among different dental schools or colleges in China, in order to find out the teaching mode of dental English education, and promote the teaching effect and cultivation of international dental talents.

    Dental access centres (DACs) were introduced in England at the turn of the twenty-first century in response to a growing problem of access to NHS dental services. DACs were expected to offer NHS dental care primarily to those patients that were unwilling or unable to attend 'high street' dental practice. At the same time, the new NHS primary care dental contract in England, introduced in April 2006, has been associated in some areas with access difficulties, with routine dental patients having difficulty accessing NHS dental care. In light of these changes, have DACs become an alternative provider of NHS dental services to patients seeking routine dental care? In summer 2007, a cross sectional dental epidemiological study was undertaken in Halton & St Helens PCT and Warrington PCT to compare the dental health and attitudes to dental visiting of adult patients attending DACs and neighbouring 'high street' dental practices. The results of the study showed that DAC patients: were younger and from a more disadvantaged background than patients attending 'high street' practices; had worse oral health than 'high street' dental patients; experienced more frequent episodes of dental pain than 'high street' dental patients and were more likely to be dentally anxious; had different attitudes to dental health than their 'high street' counterparts. The study suggests that the DACs in Halton, St Helens and Warrington are offering treatment to a different population of patients to that seen in neighbouring 'high street' practices and therefore the DACs are fulfilling the function expected of them locally.

    The aim of this study was to test a hypothesized mediation model to explain associations between mothers' dental anxiety and children's dental utilization through the mothers' own dental utilization. Two hundred and fourteen low-income African American mothers with young children (age 31-59 months) completed a study questionnaire which assessed (i) mothers' dental anxiety; (ii) mothers' dental utilization (seeing a dentist at least once a year) and (iii) children's dental utilization (at least one non-study-related dental visit during the 36-month study period). The hypothesized mediation model consisted of these three elements with both a direct path from mothers' dental anxiety to children's dental utilization and an indirect path from mothers' dental anxiety to children's dental utilization through mothers' dental utilization. Mediation analysis with bootstrapping was conducted to test the hypothesized model. The mediation analysis indicated significant total effect of mothers' dental anxiety on children's dental utilization. The standardized total effect of mothers' anxiety on children's dental utilization was -0.172 (SE=.084, P=.041), and the standardized indirect effect of mothers' anxiety on children's dental utilization mediated by mothers' dental utilization was -0.069 (SE=.039, P=.076). The direct effect from mothers' anxiety to children's dental utilization was not statistically significant (P=.261) after adjusting for the mothers' dental utilization. In this low-income African American sample, there was a trend for mothers' dental anxiety to be associated with children's dental utilization indirectly through mothers' own dental utilization, while the direct influence of mothers' dental anxiety on children's dental utilization was not seen. This suggests that mothers' dental utilization might explain how mothers' dental anxiety impacts children's early dental utilization. © 2017 John Wiley & Sons A/S.

    Dental anxiety and dental phobia typically emerge during childhood; the associated avoidance of dental care can result in oral health problems and is associated with lower quality of life. In this review, we discuss the definition of dental phobia and dental anxiety and issues related to their differentiation. We then review the literature on dental anxiety and dental phobia, including its prevalence, assessment, and sequalae. Moreover, we provide a synthesis of findings on the etiology and maintenance of dental phobia and propose a comprehensive cognitive behavioral model to guide further study. We also present a systematic qualitative and a quantitative review of the treatment literature, concluding that although we have made strides in learning how to prevent dental anxiety in youth, the methods effective in preventing anxiety may not be equally effective in treating youth with dental phobia. We propose a multidisciplinary approach, including those with expertise in pediatric anxiety as well as pediatric dentistry, is likely required to move forward. Copyright © 2017 Elsevier Ltd.

    Methacrylates are important allergens in dentistry. The study aimed to analyse patch test reactivity to 36 acrylic monomers in dental personnel in relation to exposure. We reviewed the test files at the Finnish Institute of Occupational Health from 1994 to 2006 for allergic reactions to acrylic monomers in dental personnel and analysed the clinical records of the sensitized patients. 32 patients had allergic reactions to acrylic monomers: 15 dental nurses, 9 dentists, and 8 dental technicians. The dentists and dental nurses were most commonly exposed to 2-hydroxyethyl methacrylate (2-HEMA), triethyleneglycol dimethacrylate (TREGDMA), and 2,2-bis[4-(2-hydroxy-3-methacryloxypropoxy) phenyl]propane (bis-GMA). 8 dentists and 12 dental nurses were allergic to 2-HEMA. The remaining dentist was positive to bis-GMA and other epoxy acrylates. The remaining 3 dental nurses reacted to diethyleneglycol diacrylate (DEGDA) or triethyleneglycol diacrylate (TREGDA), but not to monofunctional and multifunctional methacrylates. Our dental technicians were mainly exposed and sensitized to methyl methacrylate (MMA) and ethyleneglycol dimethacrylate (EGDMA). 1 technician reacted only to 2-HEMA, and another to ethyl methacrylate (EMA) and ethyl acrylate (EA). 2-HEMA was the most important allergen in dentists and dental nurses, and MMA and EGDMA in dental technicians. Reactions to bis-GMA, DEGDA, TREGDA, EMA and EA were relevant in some patients.

    Dental fear in children has been recognized as an important condition in patient management for many years. Its effects have been shown to persist into adulthood which can lead to dental avoidance. The aim of this study is to assess the magnitude and factors associated with dental fear among pediatric age group dental clinic attendees at Jimma University Specialized Hospital. A cross-sectional study was conducted on 240 children who visited the dental clinic. Consecutive children who came to the dental clinic participated in the study. Dental anxiety was measured using Corah's Dental Anxiety Scale (CDAS) and Dental Fear Survey (DFS). Data was collected by directly interviewing the children and their parents. Chi-square statistics were used to explore for level of significance of associations between the variables. The mean age of the study population was 10.45 years (SD = 3.19). The rate of dental anxiety in the children was found to be 74.1% ranging from moderate to severe anxiety. More than a third of the participants (36.6%) had moderate level of anxiety; 17% of them had high level of anxiety and 20.5% of them had severe anxiety. Sex of the child was not significantly associated with dental anxiety whereas age of the child was found to be significantly associated (P = 0.029). Having previous experience of dental procedure in general was not associated with the level of anxiety, however, having painful previous experience was found to be associated with higher anxiety level. Also, there was significant association is found between anxiety levels of parents and children (P dental anxiety were found to have avoidance of dental treatment. The huge burden of dental anxiety and dental fear as well as its consequent dental avoidance found in this study calls for further study. Dentists should be aware of the pervasiveness of the problem and be ready to address the issue in routine clinical care.

    The development of electronic control systems has enabled severely physically handicapped people to revolutionize their lives by using any minimal residual movements they may have to operate micro-switches linking them with typewriters and other environmetal controls. Technical skills of a high order are required in making the unique splint or interface which links the switches with these residual movements whether of the tongue, lips, chin, eyebrow, finger or toe. Through the initiative of the Cordent Trust and generous financial support from the Leverhulme Trust a mobile laboratory was designed and built and a dental technician appointed for a three-year development project in the use of these switches as it was felt that his experience was particularly appropriate to the work and would also demonstrate how dental skills can be used to bring about a degree of rehabilitation far beyond the oral environment.

    Introduction Medicaid-enrolled children with autism spectrum disorder (ASD) encounter significant barriers to dental care. Iowa’s I-Smile Program was implemented in 2006 to improve dental use for all children in Medicaid. This study compared dental home and preventive dental utilization rates for Medicaid-enrolled children by ASD status and within three time periods (pre-implementation, initial implementation, maturation) and determined I-Smile’s longitudinal influence on ASD-related dental use disparities. Methods Data from 2002–2011 were analyzed for newly Medicaid-enrolled children aged 3–17 years (N=30,059), identified each child’s ASD status, and assessed whether the child had a dental home or utilized preventive dental care. Log-linear regression models were used to generate rate ratios. Analyses were conducted in 2015. Results In 2003–2011, 9.8% of children with ASD had dental homes compared with 8% of children without ASD; 36.3% of children with ASD utilized preventive care compared to 45.7% of children without ASD. There were no significant differences in dental home rates by ASD status during pre-implementation, initial implementation, or maturation. There were no significant differences in preventive dental utilization by ASD status during pre-implementation or initial implementation, but children with ASD were significantly less likely to utilize preventive care during maturation (rate ratio=0.79, pdental home and preventive dental utilization rates were not significant (p=0.54 and p=0.71, respectively). Conclusions Among newly Medicaid-enrolled children in Iowa’s I-Smile Program, those with ASDs were not less likely than those without ASD to have dental homes but were significantly less likely to utilize preventive dental care.

    This study examines predictors of transnational dental care utilization, or the use of dental care across national borders, over a 4-year period among immigrants to Canada. Data from the Longitudinal Survey of Immigrants to Canada (LSIC, 2001-2005) were used. Sampling and bootstrap weights were applied to make the data nationally representative. Bivariate and multiple logistic regression analyses were applied to identify factors associated with immigrants' transnational dental care utilization. Approximately 13% of immigrants received dental care outside Canada over a period of 4 years. Immigrants lacking dental insurance (OR = 2.05; 95% CI: 1.55-2.70), those reporting dental problems (OR = 1.45; 95% CI: 1.12-1.88), who were female (OR = 1.59; 95% CI: 1.22-2.08), aged ≥ 50 years (OR = 2.30; 95% CI: 1.45-3.64), and who were always unemployed (OR = 1.70; 95% CI: 1.20-2.39) were more likely to report transnational dental care utilization. History of social assistance was inversely correlated with the use of dental services outside Canada (OR = 0.48; 95% CI: 0.30-0.83). It is estimated that roughly 11 500 immigrants have used dental care outside Canada over a 4-year period. Although transnational dental care utilization may serve as an individual solution for immigrants' initial barriers to accessing dental care, it demonstrates weaknesses to in-country efforts at providing publicly funded dental care to socially marginalized groups. Policy reforms should be enacted to expand dental care coverage among adult immigrants. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available 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.

    A dental chart is very useful as a standard source of evidence in the personal identification of bodies. However, the kind of dental chart available will often vary as a number of types of odontogram have been developed where the visual representation of dental conditions has relied on hand-drawn representation. We propose the Digital Dental Chart (DDC) as a new style of dental chart, especially for open investigations aimed at establishing the identity of unknown bodies. Each DDC is constructed using actual oral digital images and dental data, and is easy to upload onto an Internet website. The DDC is a more useful forensic resource than the standard types of dental chart in current use as it has several advantages, among which are its ability to carry a large volume of information and reproduce dental conditions clearly and in detail on a cost-effective basis.

    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.

    An implant-supported restoration offers a predictable treatment for tooth replacement. Reported success rates for dental implants are high. Nevertheless, failures that mandate immediate implant removal do occur. The consequences of implant removal jeopardize the clinician's efforts to accomplish satisfactory function and esthetics. For the patient, this usually involves further cost and additional procedures. The aim of this paper is to describe different methods and treatment modalities to deal with dental implant failure. The main topics for discussion include identifying the failing implant, implants replacing failed implants at the exact site, and the use of other restorative options. When an implant fails, a tailor made treatment plan should be provided to each patient according to all relevant variables. Patients should be informed regarding all possible treatment modalities following implant failure and give their consent to the most appropriate treatment option for them. PMID:19089213

    Full Text Available The term "work-related musculoskeletal disorders (WMSDs," refers to musculoskeletal disorders to which the work environment contributes significantly, or to musculoskeletal disorders that are made worse or longer lasting by work conditions or workplace risk factors. In recent years, there has been an increase in reporting WMSDs for dental persons. Risk factors of WMSDs with specific reference to dentistry include - stress, poor flexibility, improper positioning, infrequent breaks, repetitive movements, weak postural muscles, prolonged awkward postures and improper adjustment of equipment. Ergonomics is the science of designing jobs, equipment and workplaces to fit workers. Proper ergonomic design is necessary to prevent repetitive strain injuries, which can develop over time and can lead to long-term disability. In this article, 20 strategies to prevent WMSDs in the dental operatory are discussed.

    Bruxism (tooth grinding and clenching) is generally considered a contraindication for dental implants, although the evidence is usually based on clinical experience only. So far, studies to the possible cause-and-effect relationship between bruxism and implant failure do not yield consistent and specific outcomes. This is partly due to the large variation in the technical and the biological aspects of the investigations. Although there is still no proof that bruxism causes overload of dental implants and their suprastructures, a careful approach is recommended. Practical advices as to minimize the chance of implant failure are given. Besides the recommendation to reduce or eliminate bruxism itself, these advices concern the number and dimensions of the implants, the design of the occlusion and articulation patterns, and the use of a hard nightguard.

    The paper presents a conceptual framework to inform dental education. Drawing from a vast body of research into student learning, the simple model presented here has an explanatory value in describing what is currently observed to happen and a predictive value in guiding future teaching practices. We introduce to dental education the application of threshold concepts that have a transformative role in offering a new vision of the curriculum that helps to move away from the medieval transmission model of higher education towards a dual processing model that better reflects the way in which professionals operate within the discipline. Threshold concepts give a role for the student voice in offering a novice perspective which is paradoxically something that is out of reach of the subject expert. Finally, the application of threshold concepts highlights some of the weaknesses in the competency-based training model of clinical teaching. 2011 John Wiley & Sons A/S.

    The application of tribology in dentistry is a growing and rapidly expanding field. Intensive research has been conducted to develop an understanding of dental tribology for successful design and selection of artificial dental materials. In this paper, the anatomy and function of human teeth is presented in brief, three types of current artificial dental materials are summarized, and their advantages and disadvantages, as well as typical clinical applications, are compared based on the literature. Possible tribological damage of tooth structure, which is induced by complex interfacial motion, and friction-wear test methods are reported. According to results obtained by the authors and from the literature, the main progress in the area of dental tribology on both natural teeth and artificial dental materials is reviewed. Problems and challenges are discussed and future research directions for dental tribology are recommended. (topical review)

    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.

    Background: Dental anxiety and fear are major complications for both patient and dental care provider. The purpose of this study was to assess the prevalence of dental anxiety and fear in patients who referred to Isfahan Dental School and their relation to their age, gender, educational level, past traumatic experiences and frequency of dental visits. Materials and Methods: In this cross-sectional study, 473 patients were provided with a questionnaire including three sections. First section contained questions concerning their age, gender, educational level, frequency of dental visits, reasons for irregular attendance and existence of past traumatic experiences. Second section comprised a Farsi version of Modified Dental Anxiety Scale (MDAS); and third included a Farsi version of dental fear survey (DFS). Data were analyzed by t-test, ANOVA, Pearson and Spearman correlation tests. Results: The prevalence of dental anxiety among the study population was 58.8%. No correlation was found between age and MDAS (r = −0.08, P = 0.07) and DFS (r = −0.03, P = 0.53). Women demonstrated higher anxiety (P dental anxiety (r = −0.046, P = 0.32) and dental fear (r = −0.017, P = 0.79). Previous traumatic experiences were found to result in elevated anxiety and fear (P dental attendance and anxiety (r = −0.128, P = 0.008). Conclusions: Within the limitations of this study, anxiety associated with dental treatment was widespread in the study population. Dental fear and anxiety were not affected by age or education level. Dental fear and anxiety were higher in women. In addition, people who visited the dentist more regularly and individuals without previous traumatic dental experiences were less anxious. PMID:26005465

    Interprofessional and intraprofessional education (when students from two or more professions or within the same profession, respectively, learn about, from, and/or with each other) is crucial for effective interdisciplinary collaboration. The aims of this study were to assess the effectiveness of a clinical intraprofessional education program for dental and dental hygiene students, based on students' expectations and satisfaction with the program and patients' satisfaction with the team-based care. The pilot program was developed at the University of Tennessee Health Science Center College of Dentistry, where dental hygiene students were paired randomly with dental students scheduled for prophylaxis, scaling and root planing, or periodontal maintenance. Surveys with questions about the students' expectations and satisfaction were distributed to 89 senior dental students and 27 senior dental hygiene students before and after team-based procedures. Another survey was distributed to 17 patients asking about their satisfaction with the team-based care. All 27 dental hygiene students (100% response rate), 51 dental students (57.3% response rate), and all 17 patients (100% response rate) participated in the surveys. The results showed that both the dental and dental hygiene students had high expectations and were overall satisfied with the intraprofessional education. The students' expectations and perceived educational gap (difference between expectations and satisfaction) differed for the dental and dental hygiene students (ppatients were overwhelmingly satisfied with the team-based care. These results suggest that this intraprofessional practice model provided an effective educational experience for both dental and dental hygiene students and patients. The differences between the dental hygiene and dental students' expectations will help in the design of more effective training that promotes intraprofessional and interprofessional teamwork.

  18. Chronic fluoride toxicity: dental fluorosis.

    Science.gov (United States)

    Denbesten, Pamela; Li, Wu

    2011-01-01

    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

    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.

    Thermal insulative efficiency, is one of the desirable properties of the dental cements. In this study, the thermal diffusivity of three types of dental cements, were measured. Thermal diffusivity was determined by the following method. Two thermo-couples were used and connected to a chart record, the first was embedded in the cylindrical block of the cement specimen and the other in a mixing of ice and water (reference thermocouple). All them were set in a apparatus consisting of a double cooling bath. Calculation of thermal diffusivity were based on the curve provided of the record during cooling of the cement and a theoretical mathematic model. Values were ranged from 2,985 to 3,934 cm2.sec-1. ZOE cement exhibited the highest value, the glass-ionomers the lowest and the poly-carboxylates were average. The results showed that the thermal diffusivity of the cements is dependent from the type of the cement but the differences between them were not statistically significant. Additionally, the values obtained were about the same as the dentin, so the dental cements may consider as good thermal insulators.

    There has always been some degree of cheating in educational institutions. Many students who have difficulty retaining information, or who are just too lazy to work, turn to cheating as an easy way to obtain high marks. The aims of this study were to investigate undergraduate dental students' attitudes about the seriousness of thirteen cheating behaviors and to determine the students' attitudes about justification for cheating. A multiple choice questionnaire was distributed to 200 undergraduate dental students at the Faculty of Dentistry of the Jordan University of Science and Technology in the second through the fifth year of the curriculum in order to rate thirteen cheating behaviors and report their degree of satisfaction with studying dentistry. The response rate was 100 percent. Nine out of the thirteen cheating behaviors were considered as serious by about 85 percent of students. This majority also reported that they enjoyed studying dentistry compared to 10 percent who liked dentistry and 5 percent who disliked dentistry. Those 85 percent reported that they considered themselves to be ethical, while 10 percent selected somewhat ethical and 5 percent selected not ethical. This study revealed the importance of the issue of cheating and how it is evaluated by dental students who may benefit from educational programs as part of their curriculum.

    Most childhood tooth decay is preventable with a combination of fluoride--which protects the smooth surfaces of a tooth--and dental sealants--which protect tooth surfaces with irregularities called pits and fissures. Sealants are plastic coatings that protect these vulnerable areas, often narrower than a single toothbrush bristle, from decay-causing bacteria and food in the mouth. Yet, 1988-1991 data from the National Health and Nutrition Examination Survey showed that while many children still had cavities, over 80% of which were related to pits and fissures, relatively few children had sealants applied to permanent teeth. As caries has gone from a ubiquitous disease to one affecting only half of children in early elementary school and two-thirds of those who are 15 years of age, dentists must consider how to best target sealants to individual children who are at greatest risk for new disease. Most sealants are placed in private dental offices, but children at greatest risk for problems resulting from tooth decay are least likely to get private care. State and local health departments, therefore, have gone after hard-to-reach children and adolescents through school-based and school-linked sealant programs, often using portable dental equipment. This article focuses on public health strategies for community-based prevention.

  8. Occupational hazards to dental staff

    Full Text Available 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.

    To explore the undergraduate dental students' insight of their professionalism development through Focus Group Discussions (FGD). Constructivist approach using qualitative phenomenological design. Fatima Memorial Hospital, College of Dentistry, Lahore, from April to June 2011. Four FGDs of 1st year (8 students), 2nd year (6 students), 3rd year (6 students) and 4th year (6 students) enrolled in Bachelor of Dental Surgery (BDS) program were conducted to explore how they have developed various elements of professionalism namely altruism, accountability, excellence, duty and service, honor and integrity, and respect for all; and how professionalism can be further developed in them. The FGDs were audio taped, transcribed and analyzed through thematic analysis. Triangulation of themes and trends were done through content analysis by relating to their respective frequency of quotes. Data verification was done through audit by second author. Role models and social responsibility were the main reasons in the students' professionalism development thus far with personal virtues and reasons; religion; and punishment and reward contributing to a lesser degree. Training contributed least but was deemed most in furthering professionalism. Excessive workload (quota) and uncongenial educational environment were considered detrimental to the cause. Formal planning and implementation of professionalism curriculum; selection of students with appropriate attributes; control of hidden curriculum, including effective role models, good educational and working environments will foster professionalism among dental students maximally.

  11. Bacterial sex in dental plaque

    Directory of Open Access Journals (Sweden)

    Ingar Olsen

    2013-06-01

    Full Text Available Genes are transferred between bacteria in dental plaque by transduction, conjugation, and transformation. Membrane vesicles can also provide a mechanism for horizontal gene transfer. DNA transfer is considered bacterial sex, but the transfer is not parallel to processes that we associate with sex in higher organisms. Several examples of bacterial gene transfer in the oral cavity are given in this review. How frequently this occurs in dental plaque is not clear, but evidence suggests that it affects a number of the major genera present. It has been estimated that new sequences in genomes established through horizontal gene transfer can constitute up to 30% of bacterial genomes. Gene transfer can be both inter- and intrageneric, and it can also affect transient organisms. The transferred DNA can be integrated or recombined in the recipient's chromosome or remain as an extrachromosomal inheritable element. This can make dental plaque a reservoir for antimicrobial resistance genes. The ability to transfer DNA is important for bacteria, making them better adapted to the harsh environment of the human mouth, and promoting their survival, virulence, and pathogenicity.

    Titanium, as an implant material, is regarded to be durable and biocompatible, which allows functional replacement of missing teeth. Successful dental implantation depends on an osseointegration phenomenon, a direct structural and functional binding reaction between bone and implant. It is well known that physicochemical characteristics of the dental implant surface, such as roughness, topography, chemistry, and electrical charge affect the biological reactions occurring at the interface of tissue and implant. Therefore, considerable efforts have been made to modify the surface of titanium implants which are based on mechanical, physical and chemical treatments. Recently, biological molecules were introduced onto the surface of implants to stimulate osteogenic cells in the early stage of implantation and consequently accelerate bone formation around implant and subsequent rapid implant stabilization. A range of extracellular matrix components, designed peptides, and growth factors have been proposed as the biological moiety. In this review, we address several issues related to the biology of dental implants and discuss biomimetic modification of the implant surface as a novel approach to obtain successful osseointegration.

    Human teeth are anisotropic composites. Dentin as the core material of the tooth consists of nanometer-sized calcium phosphate crystallites embedded in collagen fiber networks. It shows its anisotropy on the micrometer scale by its well-oriented microtubules. The detailed three-dimensional nanostructure of the hard tissues namely dentin and enamel, however, is not understood, although numerous studies on the anisotropic mechanical properties have been performed and evaluated to explain the tooth function including the enamel-dentin junction acting as effective crack barrier. Small angle X-ray scattering (SAXS) with a spatial resolution in the 10 μm range allows determining the size and orientation of the constituents on the nanometer scale with reasonable precision. So far, only some dental materials, i.e. the fiber reinforced posts exhibit anisotropic properties related to the micrometer-size glass fibers. Dental fillings, composed of nanostructures oriented similar to the natural hard tissues of teeth, however, do not exist at all. The current X-ray-based investigations of extracted human teeth provide evidence for oriented micro- and nanostructures in dentin and enamel. These fundamental quantitative findings result in profound knowledge to develop biologically inspired dental fillings with superior resistance to thermal and mechanical shocks.

    Dental abrasion is most commonly seen at the cervical necks of teeth, but can occur in any area, even inter-dentally from vigorous and incorrect use of dental floss. Acid erosion has been implicated in the initiation and progress of the cervical lesion, while tooth-brush abrasion has long been held as the prime cause of cervical abrasion. Identification of the risk factors is clearly important in order to modify any habits and provide appropriate advice.

    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.

    In the Netherlands, the Individual Health Care Professions Act (IHCP Act) allows dental students, amongst other non-qualified individuals, to work under certain conditions in a dental practice. The aim of the study was to determine how many dental students have part-time employment in dental practice and which professional tasks they carry out. We also asked the dental students their opinion about the IHCP Act. All the enrolled dental students at the Academic Centre for Dentistry Amsterdam (ACTA) in the Netherlands received a questionnaire by e-mail. Within 1 month, two reminders were sent. The response was 44% (427 students). Of the responding students, 71% had paid employment in addition to their study. Twenty-five per cent of all students worked in a dental practice, usually 8 h a week. Study year and age were positively related to working part-time in dental practice. Activities frequently performed were providing chair side assistance, giving oral hygiene instruction, fluoride applications, scaling and root planning. The self-reported knowledge about the IHCP Act was positively related to study year and working in a dental practice. Hardly any information about the requirements of the IHCP Act with regard to delegation of tasks was provided by the employer. Many Dutch dental students work in a dental practice, taking over a variety of tasks. Although the self-reported knowledge about the IHCP Act was relatively high, many dental students expressed the need for more detailed information about the legal aspects of their tasks.

    2014-11-01

    Information crucial to the diagnosis and treatment of feline oral diseases can be ascertained using dental radiography and the inclusion of this technology has been shown to be the best way to improve a dental practice. Becoming familar with the techniques required for dental radiology and radiography can, therefore, be greatly beneficial. Novices to dental radiography may need some time to adjust and become comfortable with the techniques. If using dental radiographic film, the generally recommended 'E' or 'F' speeds may be frustrating at first, due to their more specific exposure and image development requirements. Although interpreting dental radiographs is similar to interpreting a standard bony radiograph, there are pathologic states that are unique to the oral cavity and several normal anatomic structures that may mimic pathologic changes. Determining which teeth have been imaged also requires a firm knowledge of oral anatomy as well as the architecture of dental films/digital systems. This article draws on a range of dental radiography and radiology resources, and the benefit of the author's own experience, to review the basics of taking and interpreting intraoral dental radiographs. A simplified method for positioning the tubehead is explained and classic examples of some common oral pathologies are provided. © ISFM and AAFP 2014.

    David Farrar Mitchell, DDS, PhD (1918-1975), was a pioneer in aviation dentistry and a leader in dental education, service and research. In the mid-1940's, he was the first dental officer assigned to the School of Aviation Medicine (SAM) in San Antonio, Texas, a unique, Army Air Corps organization for research and teaching. From 1942-1946, as a trained dental researcher and oral pathologist, he published works on dental problems afflicting military aviators, especially those associated with high altitude flying. His work greatly influenced ongoing dental treatment of military flyers. He served as faculty chairman of two dental schools: The University of Minnesota (1948-1955) and Indiana University (1955-1975). Of his 33 graduate students in oral pathology/medicine, 28 became department chairs at dental schools throughout the world. He was president of the American Academy of Oral Pathology (1962) and of the American Association for Dental Research (1975). From 1969 to 1975, he was editor of the prestigious Journal of Dental Research. During his professional career, Dr. Mitchell published 120 scientific articles on diverse topics relating to oral diagnosis and oral medicine.

    This study aimed to test whether socioeconomic status (SES) in childhood may affect dental visiting patterns between ages 18 and 32 years. Using data from a complete birth cohort, childhood SES status was measured (using the New Zealand Elley-Irving index) at each study stage between birth and 15 years. Longitudinal dental visiting data were available for 833 study participants from ages 15, 18, 26, and 32, and these were analyzed by trajectory analysis. Three separate dental visiting trajectories were identified; these were categorized as opportunists (13.1%), decliners (55.9%), and routine attenders (30.9%). Bivariate analyses showed low SES in childhood, male sex, and dental anxiety to be associated with membership of the "opportunist" dental visiting trajectory. Multinomial logistic regression showed that low childhood SES and dental anxiety were statistically significant predictors for membership in the opportunist or decliner trajectories after accounting for potential confounding variables. Individuals who grew up experiencing low childhood SES were less likely to adopt a routine dental visiting trajectory in adulthood than those with a high childhood SES. Dental anxiety was also an important predictor of dental visiting patterns.

  1. Functional Expression of Dental Plaque Microbiota

    2014-08-01

    Full Text Available 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.

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.

    Full Text Available Despite being a commonly studied topic, it is difficult to find studies which explain the problem of dental erosion. For this article, literature was analyzed to find information on the agents which trigger dental erosion, the main diagnosis methods, the most common treatments used nowadays and the interrelationship with dental materials. The etiology of dental erosion is multifactorial, including acids, eating disorders and gastro-esophageal reflux. However, biological factors such as saliva or habits also play a part in the establishment of this condition. In order to establish a reliable diagnosis, clinical appearance becomes decisive. The Basic Index Erosive Wear Examination (BEWE, created in 2008, is an auxiliary diagnosis tool for assessing the status and progress of the erosion. Treatment should be linked to the eradication of the causative agent and it can range from simple observational monitoring of slightly affected teeth to the placement of total crowns in the most severe cases, but this will depend entirely on the extent, severity, symptoms and type of dentition. Regarding dental materials used in the treatment of eroded parts, there are glass ionomer and composite; the latter presents the greatest resistance to biodegradation when interacting with acids. Glass ionomers are the most vulnerable material while resin is seen as the most resistant. In conclusion, dental erosion has become an issue of great importance in the dental practice because of its serious impact on dental structures. Consequently, it is ranked among the most important dental disorders in the present day.

    The authors clarified the causal mechanisms underlying the high prevalence of dental disease encountered in people who habitually use methamphetamine (meth). Using a stratified sampling approach, the authors conducted comprehensive oral examinations and psychosocial assessments for 571 study participants who used meth. Three calibrated dentists, who used National Health and Nutrition Examination Survey (NHANES) protocols, characterized the study participants' dental disease. The authors also collected data related to study participants' history of meth use and other attributes linked to dental disease. Study participants who used meth manifested higher rates of xerostomia and caries experience compared with NHANES control participants. Participants who used meth had a higher level of daily consumption of sugary beverages compared with NHANES control participants. Smoking meth did not increase caries experience over other modes of intake. Dental hygiene was a significant determinant of dental health outcomes. Mode of intake and frequency of meth use have a minimal impact on dental health outcomes. Behaviors, such as sugary beverage consumption and poor oral hygiene, better explain dental health outcomes. Having a better understanding of the causal mechanisms of "meth mouth" sets the stage for clinicians to provide more personalized interventions and management of dental disease in people who use meth.

    In Japan, there continues to be a shortage of active dental hygienists. The scope of dental hygienists' practice is also considered to be unclear. One of the reasons for this is that dental hygienists find the working conditions during dental hygiene education different from those in reality. The purpose of this study was to clarify the actual working condition of dental hygienists in dental clinics, as well as evaluate the awareness of dental hygiene students and dentists regarding the working condition of dental hygienists. Questionnaires were sent by post to 481 dentists and were distributed to 89 dental hygiene students. The awareness about the working condition of dental hygienists was compared between dentists and dental hygiene students. Two hundred twenty-two dentists and 89 dental hygiene students responded to questionnaires. Dental hygiene students considered the team of 'dental hygienist, dental technician and clerk' to be more effective in providing dental care than dentists (P working conditions, and dental team work was not always effective. For training high quality dental hygienists, all educational institutions related to dentistry must educate students regarding the more realistic dental hygienists' working condition, as well as benefits. © 2014 John Wiley & Sons A/S.

    Attitudes of dentists and dental hygienists towards extended scope and independent dental hygiene practice are described in several studies, but the results are heterogenous. The purpose of this systematic review was to compare the attitudes of dentists and dental hygienists towards extended scope and independent dental hygiene practice. PubMed, AMED and CINAHL were screened by two independent assessors to identify relevant studies. Only quantitative studies that reported the percentages of dentists' and dental hygienists' attitude towards extended scope and independent dental hygiene practice were included. The random-effects model was used to synthesise possible heterogenous influences. Meta proportions with regard to a positive attitude towards extended scope of practice are 0.54 for dentists and 0.81 for dental hygienists. Meta proportions of a positive attitude towards independent practice are 0.14 for dentists and 0.59 for dental hygienists. A meta analysis with regard to negative attitudes could only be performed on extended scope of practice and did not reveal a difference between the two professions. We obtained homogeneous outcomes of the studies included regarding negative attitudes of dentists . A minority of dentists hold negative attitudes towards extended scope of dental hygiene practice. Study outcomes regarding negative attitudes of dental hygienists were heterogeneous. Positive attitudes are present among a majority of dentists and dental hygienists with regard to extended scope of dental hygiene practice, while for independent dental hygiene practice this holds for a minority of dentists and a majority of dental hygienists. © 2016 FDI World Dental Federation.

    It has been proposed that avoidance of dental visits might be the main determinant of poor oral health outcomes in people with high dental anxiety (HDA). This study aimed to determine the predictors of dental avoidance among people with HDA and also whether these predictors differed from those found in people with lower dental anxiety (LDA). Study participants (n = 596; response rate = 41.1%) comprised a random cross-sectional sample of the Australian adult population who completed a mailed self-complete questionnaire containing items relating to the use and accessibility of dental services, trust in dental professionals, dental anxiety, dental experiences, self-perceived oral health, vulnerability-related perceptions of visiting the dentist, and psychological health. Multiple imputation was used to replace missing values and statistically significant variables in bivariate analyses were entered into a multivariable logistic generalized linear model. More than two-thirds of participants with HDA were currently avoiding or delaying a dental visit. Among people with HDA, dental avoidance was independently and significantly predicted by difficulty paying a $300 dental bill, having no or only little trust in the last-visited dentist, perceived treatment need and dental anxiety. Among people with LDA, only perceived treatment need and dental anxiety predicted avoidance. In addition to their high anxiety, a number of additional barriers to dental visiting were found for people with HDA. These barriers, especially cost and communication issues with dentists, need to be addressed to assist people with HDA obtain necessary, regular dental care. (c) 2015 APA, all rights reserved).

    To determine perceptions about dental hygiene doctoral education among dental hygiene master's degree program enrollees. In this cross-sectional national study, all dental hygiene master degree program directors were sent an email requesting they forward an attached consent form and online-survey-link to their graduate learners. The 29-item online survey assessed their perceptions about need for, importance of and interest in applying to proposed dental hygiene doctoral degree programs. A second-request was sent 1 month later to capture non-responders. Frequencies and cross-tabulations of responses were analyzed using the online software program, Qualtrics.™ Of the 255 graduate learners enrolled in 2014 reported by dental hygiene program directors, 159 completed the survey for a 62% response rate. The majority of respondents (77%) indicated that doctoral education in dental hygiene is needed for the advancement of the dental hygiene discipline and such programs are important to the dental hygiene profession (89%). Although most respondents supported both the PhD in dental hygiene and the Doctor of Dental Hygiene Practice (DDHP) degrees, more were interested in applying to a DDHP program (62%) than to a dental hygiene PhD program (38%). In addition, 43% expressed interest in enrolling in a doctoral degree program in the next 1 to 5 years and most preferred a hybrid online/onsite program format. The most frequently reported reasons for pursing a doctoral degree were: to become a better teacher, to expand clinical practice opportunities, to become a better researcher and to increase salary. Most dental hygiene master degree learners in this study believed doctoral dental hygiene education is needed and important to the dental hygiene discipline and profession, and were interested in applying to such programs.

    2014-01-01

    Background To investigate the role of geography (place of residence) as a moderator in the relationship between dental caries disease and treatment experience and dental fear in 16-year-olds living in Malaysia. Methods A multi-stage-stratified sampling method was employed. Five hundred and three, 16-year-olds from 6 government secondary schools participated in this study. The questionnaire examined participants’ demographic profile and assessed their dental fear using the Dental Fear Survey (DFS). The clinical examination consisted of the DMFT as the outcome measure of dental caries disease and treatment experience by a single examiner (ICC = 0.98). Structural equation modelling inspected the relationship between dental fear and dental caries disease and treatment experience. Results The mean DMFT was 2.76 (SD 3.25). The DT, MT and FT components were 0.64 (SD 1.25), 0.14 (SD 0.56) and 1.98 (SD 2.43) respectively. Rural compared with urban adolescents had significantly greater mean numbers of decayed and missing teeth. The mean DFS score was 40.8 (SD 12.4). Rural compared with urban adolescents had significantly higher mean scores for physical symptoms of dental fear. The correlation between dental fear (DFS) and dental caries disease and treatment experience (DMFT) was 0.29, p dental caries disease and treatment experience. The strength of the relationship between dental fear and dental caries disease and treatment experience varied in accordance with place of residence. Conclusion In conclusion a relationship between dental fear and dental caries disease and treatment experience was shown to exist in 16-year-old adolescents living in Malaysia. This study showed that the rural–urban dichotomy acted as a moderator upon this relationship. PMID:24621226

    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.

    The importance of understanding barriers to dental attendance of adults in the UK was acknowledged in the first Adult Dental Health Survey in 1968 and has been investigated in all subsequent ADH surveys. In 1968, approximately 40% of dentate adults said they attended for a regular check-up; by 2009 this was 61%. Attendance patterns were associated with greater frequency of toothbrushing, use of additional dental hygiene products, lower plaque and calculus levels. Just under three-fifths of adults said they had tried to make an NHS dental appointment in the previous five years. The vast majority (92%) successfully received and attended an appointment, while a further 1% received an appointment but did not attend. The remaining 7% of adults were unable to make an appointment with an NHS dentist. The majority of adults were positive about their last visit to the dentist, with 80% of adults giving no negative feedback about their last dentist visit. Cost and anxiety were important barriers to care. Twenty-six percent of adults said the type of treatment they had opted for in the past had been affected by the cost and 19% said they had delayed dental treatment for the same reason. The 2009 survey data demonstrated a relationship between dental anxiety and dental attendance. Adults with extreme dental anxiety were more likely to attend only when they had trouble with their teeth (22%) than for a regular check-up.

    Collaboration between dental practitioners and non-dental primary care providers has the potential to improve oral health care for people in rural and remote communities, where access to oral health services is limited. However, there is limited research on collaboration between these professional disciplines. The purpose of this paper was to explore the relationships between dental practitioners and non-dental primary care providers from rural and remote areas of Queensland and to identify strategies that could improve collaboration between these disciplines from the perspective of dental participants. Semi-structured interviews were conducted between 2013 and 2015 with visiting, local and regional dental practitioners (n = 12) who had provided dental services to patients from eight rural and remote Queensland communities that did not have a resident dentist. Participants were purposely recruited through a snow ball sampling technique. Interview data were analysed using thematic analysis with the assistance of QSR Nvivo v.10. Four major themes emerged from the data: (1) Communication between dental practitioners and rural primary care providers; (2) Relationships between dental and primary care providers; (3) Maintenance of professional dualism; (4) Strategies to improve interprofessional relationships (with subthemes: face to face meetings; utilisation of technology; oral health training for primary care providers; and having a community based oral health contact person). Participants observed that there was a lack of communication between the dental providers who saw patients from these rural communities and the primary care providers who worked in each community. This was attributed to poor communication, the high turnover of staff and the siloed behaviours of some practitioners. Visiting dental practitioners were likely to have stronger professional relationships with hospital nursing, administrative and allied health care staff who were often long term

    Many students have paid employment while studying. In the Netherlands, the Individual Health Care Professions Act (IHCP Act) allows dental hygiene students to work under certain conditions in a dental practice. The aim of the study was to determine how many dental hygiene students have part-time job employment in dental practice and which professional tasks they carry out. We also asked the dental hygiene students their opinion of the IHCP Act. All the enrolled dental hygiene students (n = 341) at a School of Health in the Netherlands received a questionnaire by email. The response was 52% (176 students). Of the responding students, 75% had paid employment in addition to their study. A proportion of the students (35%) worked in a dental practice. The median number of hours worked per week was eight. Study year, age and prior education were positively related to working part-time in dental practice. Activities frequently performed were giving oral hygiene instruction, fluoride applications, scaling and root planning, providing chair side assistance and giving local anaesthesia. Although the self-reported knowledge about the IHCP Act was high, almost half of the students expressed the need for more detailed legal information. Many dental hygiene students work in a dental practice, taking over a number of tasks usually performed by the dentist. More information in the dental hygiene curriculum about the requirements of the IHCP Act seems desirable.

    To examine the prevalence of dental anxiety and its associations with pain and other psychological variables among patients seeking dental treatment and develop a directed acyclical graph of these relationships. One hundred and twenty patients who sought regular or emergency dental care completed a semi-structured interview assessing DSM-IV specific phobia of dental procedures and questionnaires assessing dental anxiety, pain at last dental visit, blood-injection-injury (BII) phobia, social appearance anxiety, and other psychological constructs. Differences between regular and emergency patients were explored using t-tests. Potential excess risk of dental anxiety due to interactions between pain and psychological processes was explored. Finally, multivariate linear regression was conducted. Thirty-five percent of participants came for emergency care. Almost half (49.2%) reported moderate or high anxiety, and 20% met criteria for specific phobia. The relationship between pain at the last dental visit and dental anxiety scores was confounded by social appearance anxiety and BII phobia. The dental anxiety-pain response may be affected by psychological processes such as social appearance anxiety and BII phobia. Targeting these related psychological constructs may improve the management of anxiety treatment among adult patients seeking dental care. © 2014 John Wiley & Sons A/S.

    2017-09-01

    The health care system is undergoing transformation in which oral health is not only valued as an aspect of overall health, but health care delivery systems are aligning to better deliver total patient care. As a result of this transformation, education for many non-dental professionals incorporates oral health content to prepare them to practice in comprehensive delivery models. While some non-dental professionals already incorporate oral health care in their service, many opportunities exist for expansion of oral health care delivery by other non-dental professionals, including radiologic technicians, nursing staff, and human services professionals. As non-dental professionals take on expanded roles in oral health care, the dental hygiene workforce must be prepared to practice in settings with new types of professionals. Dental hygiene curricula should prioritize interprofessional education to best prepare these students for practice in evolved delivery models. This article was written as part of the project "Advancing Dental Education in the 21st Century."

    2009-01-30

    We studied the influence of a dental occlusion perturbation on postural control. The tests were performed in three dental occlusion conditions: (Rest Position: no dental contact, Maximal Intercuspal Occlusion: maximal dental contact, and Thwarted Laterality Occlusion: simulation of a dental malocclusion) and four postural conditions: static (stable platform) and dynamic (unstable platform), with eyes open and eyes closed. A decay of postural control was noted between the Rest Position and Thwarted Laterality Occlusion conditions with regard to average speed and power indexes in dynamic conditions and with eyes closed. However, the head position and stabilization were not different from those in the other experimental conditions, which means that the same functional goal was reached with an increase in the total energetic cost. This work shows that dental occlusion differently affects postural control, depending on the static or dynamic conditions. Indeed, dental occlusion impaired postural control only in dynamic postural conditions and in absence of visual cues. The sensory information linked to the dental occlusion comes into effect only during difficult postural tasks and its importance grows as the other sensory cues become scarce.

    Most used dental implants for human dental prostheses are of two steps type: first step means implantation and, after several months healing and osseointegration, second step is prosthesis fixture. For sure, dental implants and prostheses are meant to last for a lifetime. Still, there are unfortunate cases when dental implants break. This paper studies two steps dental implants breakage and proposes a set of instruments for replacement and restoration of the broken implant. First part of the paper sets the input data of the study: structure of the studied two steps dental implants based on two Romanian patents and values of the loading forces found in practice and specialty papers. In the second part of the paper, using DEFORM 2D™ FEM simulation software, worst case scenarios of loading dental implants are studied in order to determine which zones and components of the dental implant set are affected (broken). Last part of the paper is dedicated to design and presentation of a set for extracting and cutting tools used to restore the broken implant set.

    This study investigated the relationship between dental anxiety and fear, demographic and socioeconomic characteristics, and dental attendance patterns in a sample of women in Brazil. A cross-sectional study of women in healthcare centers was conducted during an immunization campaign in the city of Pelotas in southern Brazil. Interviews were conducted to assess dental anxiety and fear, education level, family income, marital status, and the use of dental services. Data were analyzed by Poisson regression models, with estimation of the prevalence ratio and the rate ratio (RR). A total of 608 women aged 16-50 years (mean age 29.3 ± 7.2 years) were included in the study. Dental anxiety and fear scores (according to Corah's Dental Anxiety Scale) ranged from 4 to 20. Of the 608 participants, 59.5 percent displayed low dental fear, 18.1 percent had moderate dental fear, and 22.4 percent displayed high dental fear. A total of 60.2 percent of the women exhibited irregular dental attendance patterns, characterized by never visiting a dentist, or only visiting when experiencing pain. After adjustments, the presence of at least moderate dental anxiety and fear was associated with low education levels (RR 1.43; 95 percent CI 1.11-1.84), low family income (RR 1.33; 95 percent CI 1.06-1.68), and irregular dental attendance patterns (RR 1.83; 95 percent CI 1.41-2.37). In this sample of Brazilian women, dental anxiety and fear were strongly associated with socioeconomic characteristics and dental attendance patterns. © 2014 American Association of Public Health Dentistry.

    There is a general consensus regarding the lack of awareness regarding the emergency management of traumatic dental injuries amongst laypersons and dental professionals. This article aims to provide an overview of the apps available for traumatic dental injuries using smartphones. These apps may serve as a gateway for raising awareness of traumatic dental injuries. Three smartphone devices were used to access their respective app stores (Nokia Lumia 635 with Windows Phone OS 8.1; iPhone 5 with iOS 8.1; Samsung Galaxy Ace II with Android OS v2.3.6 Gingerbread). Nine phrases were searched: broken tooth/teeth; chipped tooth/teeth; dental emergency; dental injury; dental trauma; fractured tooth/teeth; knocked-out tooth/teeth; tooth/teeth injury; and tooth/teeth trauma. Seven apps for the Android and one app for the Apple operating system were relevant. The only Apple iOS app retrieved (Dental Trauma) was also found for the Android OS (Dental Trauma First Aid) and had the endorsement of the International Association of Dental Traumatology. AcciDent was the only app dedicated to traumatic dental injuries targeted solely towards dental professionals. Five other apps (Chipped Tooth Solution, Dental Crown Repair, Fixing Cracked Tooth, Repairing the Front Tooth and Solution to Broken Tooth) appeared to come from the same source (KBES). No traumatic dental injury apps were found for the Windows Phone OS. There are apps available for both patients and dentists that range in quality and on the whole lack real-life photographs. Future apps should continue to provide good quality, evidence-based and validated material. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    The aim of this study was to assess the relationship between burnout, depressive symptoms and suicidal ideation in dental and dental hygiene students and to evaluate the influence of gender, programme type and year of study. Third- and fourth-year dental (DS) and first- and second-year hygiene students (DHS) completed the Patient Health Questionnaire (PHQ-9) and an abbreviated Maslach Burnout Inventory online as measures of depressive symptoms/suicidality and burnout, respectively. The statistical analyses included summary statistics and tests for intergroup comparisons (chi-square) to evaluate the influence of gender, programme type (DHS or DS) and year of study. Correlations between depression, suicidality and burnout were also conducted. A total of 32 dental hygiene and 119 dental students participated. 40% of the dental and 38% of the hygiene students met criteria for burnout. No differences were found between years or between programmes. Nine per cent of both dental and hygiene students were above the cut-off for moderate depressive symptoms, but there were no statistical differences between the third- and fourth-year dental and the first- and second-year hygiene students. Six per cent of the dental and 9% of the dental hygiene students were above the cut-off for clinically significant suicidal ideation, but there were no statistical differences between dental and hygiene students. There were no differences noted in the dental students based on gender for any of the measures. Depression was significantly associated with all three subscales of burnout. Suicidal ideation was only significantly related to the lack of personal accomplishment subscale of burnout. These findings suggest the need for introducing preventive measures for such affective states in dental and dental hygiene training programmes. © 2017 John Wiley & Sons A/S.

  19. Dental enamel, fluorosis and amoxicillin

    Directory of Open Access Journals (Sweden)

    I. Ciarrocchi

    2012-06-01

    Full Text Available Introduction: Amoxicillin is one of the most used antibiotics among pediatric patients for the treatment of upper respiratory tract infections and specially for acute otitis media (AOM, a common diseases of infants and childhood. It has been speculated that the use of amoxicillin during early childhood could be associated with dental enamel fluorosis, also described in literature with the term Molar Incisor Hypomineralization (MIH, because they are generally situated in one or more 1st permanent molars and less frequently in the incisors. The effect of Amoxicillin seems to be independent of other risk factors such as fluoride intake, prematurity, hypoxia, hypocalcaemia, exposure to dioxins, chikenpox, otitis media, high fever and could have a significant impact on oral health for the wide use of this drug in that period of life. Objective: The aim of this work was to review the current literature about the association between amoxicillin and fluorosis. Methods and Results: A literature survey was done by applying the Medline database (Entrez PubMed; the Cochrane Library database of the Cochrane Collaboration (CENTRAL. The databases were searched using the following strategy and keywords: amoxicillin* AND (dental fluorosis* OR dental enamel* AND MIH*. After selecting the studies, only three relevant articles published between 1966 and 2011 were included in the review. Conclusion: The presence of several methodological issues does not allow to draw any evidence-based conclusions. No evidence of association was detected, therefore, there is a need of further well-designed studies to assess the scientific evidence of the relationship between amoxicillin and fluorosis and to restrict the prescription of this drug for recurrent upper respiratory tract infections especially acute otitis media (AOM during the first two years of life. When it is possible can be opportune to use an alternative antibiotic treatment.

    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.

    Laboratory studies show that digital intraoral radiography systems are as accurate as dental film for the detection of caries when a good-quality image is obtained, although more re-takes might be necessary because of positioning errors with the digital systems, particularly the charge-coupled device sensors. The phosphor plate is more comfortable for the patient than nondigital systems, and the dose can be further reduced with the storage phosphors. Cross-contamination does not pose a problem with digital systems if simple hygiene procedures are observed.

    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.

    The roentgenologic diagnosis of lateral subluxation of the atlanto-axial joint is very difficult because the only presentation is increase of the atlanto-dental interval. This study was carried out with 70 volunteers for normal value of atlanto-dental interval. We measured these intervals from lateral roentgenograms of cervical spine in neutral, flexion, and extension position of the neck. The results were as follows: 1. The mean value of atlanto-dental interval in all subjects was 1.54+-0.52mm in neutral, 1.59+-0.62mm in flexion, and 1.46+-0.48mm in extension position. 2. After thirty years of age the atlanto-dental interval was getting narrower according to aging. 3. In neutral and flexion positions there is no difference in atlanto-dental intervals, but in extension position it was significantly narrowed.

    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.

    The aim of this study was to determine the factors that affect Jordanian dental hygienists with their career satisfaction including financial issues, employment settings and policies. Randomized sample of 102 dental hygienists with a bachelor's degree were selected from the entire population of Jordanian dental hygienists. Participants received a cover letter with a questionnaire. Findings were analysed using descriptive data techniques. Chi-square test was used to determine the statistically significant differences across demographic variables and career satisfaction's factors. About 22.5% of the participants are not working as dental hygienist. Dental hygiene profession in Jordan includes predominantly (74.0%) females. Majority of them (51.9%) were employed in JUST, and minority (6.3%) in MOH. Most of them (56.4%) were aged 24-29 years old, and mostly 62.2% with ≤1 child. About 53.1% employed by general dentist. Almost 35.3% had ≥4 years' job experience. Majority (47.6%) expressed high level of satisfaction with dental materials and equipment to practice work; however, only 2.0% expressed very high level of satisfaction with employment policies. Almost 32.4% expressed low level of satisfaction with salary level. Minority (2.0%) expressed dissatisfaction with quality of dentist's work. Statistically significant association was found between workplace, and dental materials and equipment to practice work, salary level, employment policies (P = 0.003, P = 0.003, P = 0.026), and number of children with flexibility in work hours (P = 0.001).

    To describe dental and dentofacial characteristics observed in patients diagnosed with osteopetrosis and to advise a dental care approach in these patients. Four patients were clinically diagnosed with osteopetrosis, characterised by increased bone density, bone marrow failure, blindness and deafness due to compression of cranial nerves. All patients were dentally screened at different ages (2.5-31 years) and three of them were treated with a haematopoietic stem cell transplantation (HSCT) at the age of 6 months, 1 and 3.1 years. All patients showed similar dental characteristics but varying severity and extent. Dental pits, abnormalities in form, agenesis and enamel deformations are seen. The eruption of the permanent dentition occurs at a slow rate, primary teeth can persist, have no successor, and aberrant form of the primary/permanent teeth can delay eruption. Uneven surfaces and atypical dental crowns combined with visual impairment make brushing of the teeth and plaque removal more difficult to manage. Dental problems such as delay in tooth eruption, crown anomalies and agenesis are seen in the patients diagnosed with osteopetrosis, although the severity and extensiveness of the symptoms differ and possibly depend on the age of the patient at HSCT. Treatment management: Frequent dental follow-up examinations are necessary for guiding the eruption and professional dental cleanings. Aid in the eruption can be helpful. In the case of surgical interventions, an antibiotic prophylaxis is advised. A fluoride treatment can be added to prevent caries. The role of HSCT in dental findings needs further research.

    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.

    The purpose of this study was to find out the prevalence of dental anomalies in 600 normal persons (male:363, female:237) at age 14 to 39 years, through history taking, oral examination, and radiographic observations of subjects. The obtained results were as follows: 1. The prevalence of individual dental anomalies were as follows; Congenitally missing teeth 7%; supernumerary teeth 1.33%; ectopic eruption 8.50%; transposition 0.33%; rotation 23.67%; microdontia 11.16% (peg lateral is 5.33%; third molar 5.83%); prolonged retention of deciduous teeth 1.33%; crowding 49.83%; and spacing 15.17%. 2. Alterations in numbers of teeth : The most frequently missing teeth were mandibular lateral incisors, followed by mandibular second premolars and maxillary second premolars. In numbers of congenitally missing teeth per person, 52.38% had one missing tooth and 30.95% had two missing teeth. In supernumerary teeth, there was higher rate in male than in female. Most supernumerary teeth were mesiodens of median area in maxilla and the eruption pattern of that teeth generally was unerupted state. 3. In transposition, exchange of position of teeth involved the canine and first premolar. 4. Congenital missing rate of permanent successors in prolonged retention of deciduous teeth was 69.23%. 5. Crowding and spacing had respectively higher rate in mandible and in maxilla.

  16. Dental infection and vascular disease.

    Zoellner, Hans

    2011-04-01

    Periodontitis is a chronic inflammatory response to bacterial plaque in which the anchoring bone and soft tissues supporting teeth are destroyed, resulting in tooth mobility and loss. Dental caries involves the spread of infection from the dentine to the vascular dental pulp and periapical bony tissues, before involvement of adjacent soft tissues and spreading sepsis. Several case-controlled, cross-sectional, and cohort studies report correlation between periodontitis and increased cardiovascular, cerebrovascular, and peripheral artery disease, as determined by clinical disease, angiography, ultrasonography, and reduced flow-mediated dilation. Some studies report a similar relationship of atherosclerosis with periapical infection and potentially also with coronal caries, and this review identifies the need to investigate these associations further. Smoking and cadmium exposure are epidemiologically confounding environmental risk factors shared by atherosclerosis and periodontitis. Further complicating epidemiological studies are the risk factors for both atherosclerosis and periodontitis, with which periodontitis appears to have separate positive feedback relationships. These include diabetes, increased plasma lipid levels, hypertension, and white blood cell count. Animal and human intervention studies provide some direct support of a causal role for periodontitis in atherosclerosis, and possible mechanisms include bacterial invasion of arteries, specific atherogenic properties of oral bacteria, the acute phase response, and cytokine polymorphisms. © Thieme Medical Publishers.

    This study assessed the current employment status of dental hygienists practicing in Hong Kong, investigated factors affecting their employment, evaluated the satisfaction of local dental hygienists and their employers, and explored the career prospects of dental hygienists in Hong Kong. All registered dental hygienists (n = 64), all dentists who employed dental hygienists (n = 25), and a systematic sample of dentists who did not employ dental hygienists (n = 278) were surveyed in June 1994 concerning employment situation, salaries, job satisfaction, and opinions on future prospects for dental hygienists. Response rates were 86% for dental hygienists (n = 55), 88% for employers (n = 22), and 63% for dentists at large (n = 175). Among the dental hygienists, 87% still were employed as dental hygienists, and both the dental hygienists and their employers agreed that the employment situation was satisfactory; however, several dental hygienists were considered to be working below their level of qualification. Major reasons for dentists not to employ a dental hygienist were having only one operatory and having an inadequate number of patients. In general, employers expressed satisfaction with the performance of the dental hygienists. Major reasons for employing a dental hygienist were that a dental hygienist would add professional and economical benefit to their clinic. Few dentists would support expanded duties for dental hygienists. In Hong Kong, dental hygienists and their employers comprise a small group with limited impact on oral healthcare services. Dental hygienists' perceptions of their future roles and ambitions are higher than those of their employers. To further the development of dental services in Hong Kong and meet documented oral healthcare needs in the population, greater utilization of dental hygienists should be promoted.

    2012-03-01

    To assess dental fluorosis, dental caries and quality of life factors associated with dental fluorosis among schoolchildren living in a Colombian endemic dental fluorosis area. 110 12-year olds were visually examined for dental caries (ICDAS) and dental fluorosis (TF) and a self-administered quality of life and fluorosis questionnaire was applied. The prevalence of dental fluorosis reached 100% in this sample with most children falling within the TF 3 severity category. Varying degrees of severity were observed as follows for TF 1 to 6: 1%, 16%, 62%, 16%, 4%, 2%. The prevalence of caries experience (DF-S2) was 54%. The DF-S2 mean was 4.4 (sd 4.3). The principal contributor to the DF-S2 outcome was the decayed component. When initial caries lesions were included (ICDAS-scores 1-3) the mean DF-S1,2 increased to 10 (sd 5.1). The association between fluorosis and dental caries was not statistically significant (p > 0.05). Children not only detected the presence of something abnormal in their teeth but also reported feeling embarrassed, and worried due to their dental appearance. Almost 60% of the children reported avoiding smiling because of their teeth's appearance. The high prevalence of dental fluorosis and dental caries combined with the schoolchildren's negative perception about their dental health reflects the need to propose effective dental public health policies to regulate multiple exposures to fluoride at an early age, and to improve health outcomes in a highly vulnerable population.

  19. Dental caries, age and anxiety: factors influencing sedation choice for children attending for emergency dental care.

    2001-02-01

    The aim of the study was to examine how physical (dental caries) and psychosocial (age, dental anxiety and dental health behaviour) factors, associated with child and parent, influenced dentists' sedation choice when a child presents in pain. 600 parents whose children were aged between 5 and 11 years took part: 200 attended for routine dental care (RDC); the remaining 400 attended as emergency patients and were offered either dental general anaesthesia (DGA) or relative analgesia (RA). The subjects were approached and invited to take part. The researcher was blind as to the child's pattern of dental attendance and the type of sedation offered. All parents and children completed self-reported ratings of dental anxiety. The children's teeth were examined to determine past and present dental caries experience. The results showed that children who were offered DGA had greater experience of dentinal caries, were younger and dentally anxious. The children offered RA were older, had a higher frequency of brushing their teeth with fluoride toothpaste and were also dentally anxious. Discriminant analysis showed that 2 canonical functions provided clear categorisation of the three treatment groups. Function 1 was a physical (dental caries) factor, which was related to the child's experience of dentinal caries. Function 2 was a psychosocial factor, which was related to the child's age, dental anxiety and frequency of tooth brushing. A greater proportion of the variance in the treatment offered was explained by Function 1, suggesting that the most important factor in the decision to offer DGA was dentinal caries. Function 2 was of lesser importance. The findings have implications for the type of sedation offered to children presenting for emergency care. These children may not otherwise receive treatment and the need to provide less anxiety provoking forms of sedation must be promoted. By doing so, parents who have only brought their children when in pain may take advantage

    A medium- and long-term perspective is required in human resource development to ensure that future needs and demands for oral healthcare are met by the most appropriate health professionals. This paper presents a case study of the Sultanate of Oman, one of the Gulf States with a current population of 3.8 million, which has initiated dental training through the creation of a dental college. The objectives of this paper are first to describe trends in the dental workforce in Oman from 1990 to date and compare the dental workforce with its medical counterparts in Oman and with other countries, and second, to consider future dental workforce in the Sultanate. Data were collected from published sources, including the Ministry of Health (MoH), Ministry of Manpower (MoM), and Ministry of National Economy (MoNE)-Sultanate of Oman; the World Health Organization (WHO); World Bank; and the Central Intelligence Agency (CIA). Dentist-to-population ratios were compared nationally, regionally and globally for medicine and dentistry. Dental graduate outputs were mapped onto the local supply. Future trends were examined using population growth predictions, exploring the expected impact in relation to global, regional and European workforce densities. Population growth in Oman is increasing at a rate of over 2% per year. Oman has historically been dependent upon an expatriate dental workforce with only 24% of the dentist workforce Omani in 2010 (n = 160). Subsequent to Oman Dental College (ODC) starting to qualify dental (BDS) graduates in 2012, there is an increase in the annual growth of the dentist workforce. On the assumption that all future dental graduates from ODC have an opportunity to practise in Oman, ODC graduates will boost the annual Omani dentist growth rate starting at 28% per annum from 2012 onwards, building capacity towards global (n = 1711) and regional levels (Gulf State: n = 2167) in the medium term. The output of dental graduates from Oman Dental College is

    Karnad, Maya P Rao

    2015-01-01

    Dental anxiety is well documented within dental literature, and is a condition with which dentists and dental care professionals alike will be familiar. Its consequences may extend beyond dental implications alone, but can also have the potential to affect a patient's quality of life. It is important that as a dental profession we are aware of the methods which can be used to manage various forms of dental anxiety, and to refer to specialist services as appropriate. This paper focusses on detailing both the evidence-based behavioural and pharmacological strategies that may be employed for both dentally anxious adults and children.

  14. Dental screening of pediatric cardiac surgical patients.

    Hayes, P A; Fasules, J

    2001-01-01

    Dental screenings were completed on 209 pediatric patients six months and older that were scheduled for cardiac surgery from two different geographical locations. The screening involved an educational session on bacterial endocarditis and preventive dentistry followed by a dental examination. We found that sixty-two (30 percent) patients had seen a dentist regularly, ninety-three (44 percent) practiced daily oral hygiene and thirty-seven (18 percent) knew about bacterial endocarditis. Local dentists performed invasive procedures on seventy-one (34 percent) patients and thirty-four (48 percent) received antibiotic prophylaxis. Only twenty-three (68 percent) of the thirty-four patients received the then current American Heart Association antibiotic regimen. Dental disease was diagnosed in 175 (84 percent) of the 209 patients: 164 (78 percent) gingivitis; sixty (29 percent) caries; six (7 percent) dental abscess; three (1 percent) periodontal abscess; five (2 percent) periocornitis. Cardiac surgery was postponed in twenty-four (12 percent) patients. We conclude that parents lacked knowledge about bacterial endocarditis even after being informed during their routine cardiology visit, there appears to be a deficiency of knowledge among dentists regarding the indications and antibiotic regimen required to prevent bacterial endocarditis, and all cardiac surgical patients should have a dental exam and preventive dental program implemented prior to six months of age and dental screening prior to their cardiac surgery.

    2007-09-01

    To present data on hemodynamic changes during dental extractions in 5 patients with cardiac sarcoidosis, performed with electrocardiogram, heart rate, and blood pressure monitoring throughout the procedures, and to discuss the problems relating to the disease and dental extraction. The medical data for 5 patients, including medical records, physician correspondence, and laboratory data before the treatments, were assessed. Seven dental extractions were then performed while monitoring and recording the hemodynamic conditions. Heart rate, blood pressure, rate pressure products, and electrocardiographic findings were analyzed. Finally, posttreatment evaluations of the general and local conditions of the patients were conducted. All dental extractions were performed in nonactive stable periods, with no remarkable hemodynamic changes or complications, while maintaining a stable hemodynamic state throughout the extraction procedure. All patients received a pretreatment supplement of corticosteroid. Wound healing was similar to that in normal patients under antibiotic prophylaxis against infection originating from the dental extraction wound and the original dental lesion. Pretreatment general evaluation of patients with cardiac sarcoidosis should be performed through various examinations and physician consultation, and a stable hemodynamic change during the surgical procedure should be maintained under any hemodynamic monitors. Corticosteroid supplement and antibiotic coverage are also necessary for safe dental extraction and suitable healing.

  16. Psychophysiological reactivity of currently dental phobic-, remitted dental phobic- and never-dental phobic individuals during exposure to dental-related and other affect-inducing materials.

    Wannemueller, André; Adolph, Dirk; Joehren, Hans-Peter; Blackwell, Simon E; Margraf, Jürgen

    2017-03-01

    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.

    In recent years the topic of dental tourism has increasingly come into focus of dentists and patients. In the present study an attempt was made to find out, why patients from a restricted region travel to Germany for dental care. In five German dental clinics located in the border area between Switzerland and Germany, 272 women and 236 men ranging in age from 5 to 94 years, who had undergone at least one dental treatment in Germany, were questioned concerning the reasons for their visits. The interviews took place within a period of 6 months and relied on a questionnaire to collect data regarding sociodemographic features and patient behavior. In comparison to residents of Germany, patients residing in Switzerland took on considerably longer travel distances for the dental visit, in some cases more than 50km (9.7%). For patients residing in Switzerland the technical equipment of the practice was more important (pSwitzerland (95.6%) confirmed that dental treatments in Germany were cheaper and that additional family members also came to Germany for dental care (65.0%).

    2002-02-01

    Dental Internet portals can offer dental practitioners "one-stop shopping" for many information needs. To date, no studies have described and evaluated dental portals' services and content. The authors evaluated five dental portals from Jan. 22, 2001, to April 5, 2001, using 90 evaluation criteria in seven categories: general, services, miscellaneous, navigation and usability, site currency, site performance and responsiveness, and site integrity. Groups of three to four dental students rated each portal. The authors rated certain criteria using commercial monitoring and analysis services. The portals evaluated in this study provided a wide range of services such as product purchasing, online continuing education, practice management services, news, dental practice Web pages and event calendars. Portals differed in many characteristics, such as the number of services, product pricing, discussion forum activity, navigability, reaction time in response to questions and site responsiveness. The implementation and usefulness of each portal's services varied. No portal can fit all needs best, and many portals change rapidly owing to the volatility of the Internet industry. Dentists should be familiar with portals' services and alternatives for using them. Portals can provide useful services to dental practitioners. Practitioners, however, should evaluate portals carefully to ensure that their needs are met optimally.

    The aim of this study was to describe a new dental hygiene education program for nursing staff and to report experiences from the program at a nursing home in Stockholm, Sweden (2006). This strategy comprises 3 steps. The first is individual instruction for nursing staff about oral care for patients and hands-on training in toothbrushing technique using an electric toothbrush. The second step was small discussion groups of 4 to 8 nursing staff, led by a dental hygienist and a psychologist. The third step was a theoretical lecture focusing on the associations among dental hygiene, oral health, and general health among the elderly. During the dental hygiene education program, a negative attitude toward oral care was noted among members of the nursing staff, although they did consider oral care important for their patients. Increased self-confidence of staff in providing oral care was noted after completing the dental hygiene education program. Nursing staff members stated that they had received more detailed knowledge about oral care during the program. This dental hygiene education program appears to result in increased knowledge and interest in oral hygiene tasks among the nursing staff and may lead to improved dental hygiene among nursing home residents.

    To assess the psychosocial impact of dental aesthetics using the 'Psychosocial Impact of Dental Aesthetics Questionnaire' (PIDAQ) and self-rated Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN). Cross-sectional study. Dental Section, the Aga Khan University Hospital, Karachi, from August to September 2006. Adults with no prior orthodontic treatment were asked to complete a modified version of the 'Psychosocial Impact of Dental Aesthetics Questionnaire' (PIDAQ). A total of four variables including 'Dental Self-confidence', 'Social impact', 'Psychological impact' and 'Perceived orthodontic treatment need' were assessed by a series of statements, whereas dental aesthetics were assessed by the respondents using the IOTN Aesthetic Component (self-rated IOTN-AC). Kruskal-Walli's test was applied to determine significance. The respondents were 120 adults (70 females and 50 males; mean age 25.8 years), all four of the above-mentioned variables measuring psychosocial impact showed positive and significant correlations with the perceived severity of malocclusion as depicted by the Aesthetic Component (AC) of Index of Orthodontic Treatment Need (IOTN), with p-value of less than 0.01 for all variables. The results indicate the strong psychosocial impact of altered dental aesthetics on the emotional state of an individual. The association between self-rated IOTN-AC grading with psychosocial well-being stands established, indicating that the perceived aesthetics of malocclusion may be as significant a factor in determining treatment need as the degree of malocclusion.

    To develop prediction models of the relative need for care to differentiate between urgent and not urgent individuals presenting for emergency dental care. Data were collected from 839 adults presenting to public dental clinics across South Australia (SA) and New South Wales (NSW) for emergency dental care. Prediction of the urgency of emergency dental care was based on the assessment of two binary logistic regression models - Model 1: urgency of care=dental care were developed using binary logistic regression analysis. The models incorporated subjective oral health indicators (i.e., experience of pain or other oral symptoms) and measures of psychosocial impact of oral disorders (i.e., difficulty sleeping and being worried about the appearance/health of one's teeth or mouth). The cut-off point for the prediction of urgency was defined as a probability value > or =0.40 and > or =0.50 for Model 1 and Model 2 respectively. These cut-off values were chosen as they produced test results that were consistent with the proportions of patients falling into various urgency categories derived from dentist's assessment of urgency. Model 1's sensitivity was 58%, specificity 77% and positive predictive value (PPV) 59%. Model 2's sensitivity was 75%, specificity 65% and PPV 71%. These models of relative need may be useful tools for the screening of urgent dental care and for allocating priority among patients presenting for emergency dental care.

    The safety of mercury-containing dental amalgam has been hotly debated for well over a century. Dental exposures from mercury have been suggested as the cause of numerous diseases including multiple sclerosis, autism and many others. Known health effects of mercury exposure include CNS and renal damage. However, these effects have only been shown at occupational or higher levels of exposure, and have not been conclusively shown to be present at levels of mercury exposure consistent with that from dental amalgam fillings. The use of mercury amalgam fillings remains a state-of-the-art treatment for dental caries throughout the world. Although there have been a small number of peer-reviewed reports examining the health effects of dental mercury in children, only very recently have the only randomised, controlled clinical trials (two) of the safety of mercury amalgam been published. The purpose of this review is to discuss the scientific evidence on the safety of the use of mercury-containing dental amalgam as a treatment for dental caries.

    The poor oral health of nursing home residents is the cause of substantial morbidity and has major implications relating to health care policy. The aim of this study was to measure dental caries experience in Australians living in nursing homes, and investigate associations with resident characteristics. Clinical dental examinations were conducted on 243 residents from 19 nursing homes in Melbourne. Resident characteristics were obtained from nursing home records and interviews with residents, family and nursing home staff. Two dental examiners assessed coronal and root dental caries using standard ICDAS-II criteria. Residents were elderly, medically compromised and functionally impaired. Most required assistance with oral hygiene and professional dental care was rarely utilized. Residents had high rates of coronal and root caries, with a mean 2.8 teeth with untreated coronal caries and 5.0 root surfaces with untreated root caries. Functional impairment and irregular professional dental care were associated with higher rates of untreated tooth decay. There were no significant associations with medical conditions or the number of medications taken. Nursing home residents have high levels of untreated coronal and root caries, particularly those with high needs due to functional impairment but poor access to professional services. © 2014 Australian Dental Association.

    The assessment of dental anxiety among children will aid in dealing with management issues related to dental treatment. There is no study available from Pakistan on dental anxiety in children. The aim of this study was to assess the prevalence of dental anxiety in children attending a teaching dental hospital in Islamabad, Pakistan. A cross-sectional study was conducted on 252 children aged between 5-10 years attending a dental clinic in a dental hospital in Islamabad, Pakistan. Dental anxiety was assessed by using the Faces Version of the Modified Child Dental Anxiety Scale. This scale uses faces as pictograms to indicate the levels of dental anxiety making it easier for children to answer the questionnaire. A total of 252 children were observed for assessment of dental anxiety having mean age of 7.88±1.55 years with 123 (48.8%) males and 129 (51.2%) females. Out of these children 150 (59.5%) had previously visited a dentist and 102 (40.5%) had no experience with a dentist before; 38% (95/252) of children had moderate and severe dental anxiety. Dental anxiety decreased significantly with age (p=0.0003). The difference in anxiety levels was not statistically significant between males and females and in different socio-economic status. This study has highlighted dental anxiety as a potential public health concern regarding children in Pakistan. Assessment of dental anxiety is a useful way to identify anxious dental patients.

    with today's 21st century technological advancements, it is expected that individuals will either retain their natural teeth or obtain functional tooth replacements throughout their entire life. Modern dental therapies for the replacement of missing teeth largely utilize partial or complete dentures and titanium implants capped with prosthetic crowns. Although these prostheses serve a purpose, they are not equivalent, neither in function nor aesthetics, to natural teeth. Recent progress in dental tissue engineering has lent significant credibility to the concept that biological replacement teeth therapies may soon be available to replace missing teeth. in this review, we summarize the emerging concepts of whole-tooth replacement strategies, using postnatal dental stem cells (DSCs) and dental tissue engineering approaches. we provide a thorough and extensive review of the literature. current approaches to achieve clinically relevant biological replacement tooth therapies rely on the cultivation of DSCs capable of relaying odontogenic induction signals, through dental epithelial-mesenchymal cell interactions. DSC expansion and differentiation can be achieved by programming progenitor stem cells to adopt dental lineages, using instructive, bioengineered scaffold materials. Periodontal ligament regeneration in particular has demonstrated significant progress recently, despite the somewhat unpredictable clinical outcomes, with regard to its capacity to augment conventional metallic dental implants and as an important component for whole-tooth tissue engineering. Following recent advances made in DSC and tissue engineering research, various research groups are in the midst of performing 'proof of principle' experiments for whole-tooth regeneration, with associated functional periodontal tissues. This mini-review focuses on recent and promising developments in the fields of pulp and periodontal tissue DSCs that are of particular relevance for dental tissue and whole

  9. Radiopacity of Dental Materials: An Overview

    2016-06-01

    Full Text Available Context This study aimed to provide an overview of the literature on the radiopacity of dental materials in order to emphasize its importance. Evidence Acquisition English-language literature was investigated using manual and electronic searches for the terms “radiopacity,” “dental material,” “cement,” “composite,” “ceramic,” “endodontic root canal sealer,” “bone graft,” and “acrylic resin” in the databases of Medline, google scholar, and Scopus up to April 2016. Seventy-nine selected publications, including review articles, original articles, and books, were evaluated. Results The radiopacity of different dental materials may be lower or higher than that of the replaced tissue depending on the restorative material used. The research revealed that highly-radiopaque materials should not be used in dental restorations, except as bone graft and endodontic root canal filling materials. For most of the dental restorative materials, moderate radiopacity within the range of the replaced dental tissue is recommended. However, the lower radiopacity of polymer-based restorative or prosthetic dental materials is still a significant clinical problem. Conclusions The author recommends using highly-radiopaque materials whenever possible for treatment of bone defects and root canals. For dental materials that replace clinical crowns, the radiopacity should be within the range of that of the replaced tooth structure (dentin or enamel. The radiopacity of dental cements should be much higher than that of the enamel in order to facilitate detection of the thin cement remnants.

    2017-05-01

    This is the second paper in a two-part series discussing the management of common restorative dental emergencies. The first paper focussed upon problems relating to conventional fixed and removable restorations, and this paper discusses the management of common dental implant related emergencies. With dental implant treatment becoming an increasingly popular method of replacing missing teeth, it is very likely that dentists working in general practice will routinely come across patients who have previously undergone this form of treatment, even if they themselves are not directly involved in placing or restoring dental implants. This paper is aimed at general dental practitioners (GDPs) who have some experience in managing dental implants, and those who want to gain further insight into how such situations may be managed.

    Since the 2000s, different epidemiological studies focusing on the prevalence or the aetiology of DE in adolescents recognised them as an at-risk population due to their eating behaviours. None was carried out in French adolescents. The primary objective of this study was to assess the prevalence of dental erosion (DE) using the total BEWE score among adolescents in the department of Alpes Maritimes, France. The secondary objectives were to observe changes in prevalence estimates depending on both the cutoffvalue of total BEWE score with different teeth/dental surfaces examined, and to identify the related risk factors. A cross-sectional study in a multistage random sample of 339 14-yr-old schoolchildren was carried out in 2014. The children completed a self-administered questionnaire concerning diet and oral habits. Caries was assessed with ICDAS-II (International Caries Detection and Assessment System-II) criteria and erosion with BEWE (Basic Erosive Wear Examination) index. The total BEWE score was calculated to assess the DE prevalence with two cutoff values (3 and 1). Data were analysed using descriptive statistics and logistic regression models. The 331 children were aged 14.4 ± 0.5 years. The DE prevalence was 39 % using a total BEWE score ≥ 3. With a cutoff total BEWE score of 1 (at least one affected tooth), the prevalence varied from 3.9 to 56.8 % depending on the teeth/surfaces that were used for the analysis. The DE prevalence, assessed with only first molars and maxillary incisors, was about 54 %. The risk factors for DE (total BEWE score ≥ 3) were daily consumption of acidic beverages (OR: 4.0; 95 % CI: 2.1-7.6) and acidic sweets (OR: 3.2; 95 % CI: 1.2-8.0), low socio economic category (OR: 2.4; 95 % CI: 1.1-5.0) and visible dental biofilm (OR: 2.0; 95 % CI: 1.2-3.4). Depending on the method chosen, the prevalence varied from 3.9 to 56.8 % among these adolescents. Thus, a consensus on choice of index, teeth to examine and age at

    Children with significant baby bottle tooth decay and children who are challenged by significant physical and emotional limitations are candidates for dental rehabilitaion procedures with general anesthesia. Rehabilitation of children's primary teeth is important to prevent pain, infection, and tooth loss. To provide skilled care for children undergoing dental rehabilitation procedures, perioperative nurses must understand normal dentition, tooth anatomy, and caries prevention and formation and be able to meet children's developmental and emotional needs. Perioperative nurses also must collaborate with dentists to maintain appropriate supply inventories that are unique to dental rehabilitation procedures.
