Full Text Available Las sinusitis odontógenas son una patología relativamente frecuente causada por infecciones dentales, quistes periapicales así como tras procedimientos bucodentales como una endodoncia, una elevación sinusal o la colocación de un implante. A continuación se presenta un caso extremo de una pansinusitis derecha con fistulización a espacio epidural causada por un implante osteointegrado. Ante la sospecha de una sinusitis maxilar de origen odontogénico se debe iniciar rápidamente un tratamiento antibiótico correcto y un seguimiento estrecho ya que pueden tener consecuencias fatales como la pérdida de un ojo, abscesos cerebrales o incluso la muerte.Odontogenic sinusitis is a relatively common disease caused by dental infections, periapical cysts and oral procedures such as root canal, sinus lift or implant placement. We report an extreme case of a right pansinusitis with an epidural space fistula caused by osseointegrated implants. When maxillary sinusitis of odontogenic origin is suspected, we should quickly start effective antibiotic treatment and monitor the patient closely because odontogenic sinusitis can have serious consequences, such as the loss of an eye, brain abscess or death.

Isidro de Jesús Nápoles González

Full Text Available La higiene bucal proviene de épocas remotas. En la era primitiva el hombre empleaba sus uñas o fragmentos de madera, en la prehispánica los indígenas utilizaban la raíz de una planta o se frotaban los dientes con los dedos. Pero el cepillo de dientes tal y como hoy se conoce comenzó a utilizarse en el siglo XVII. En su diseño se han combinado diferentes tipos, tamaños y grosores de cerdas, dispuestas en distintas angulaciones para facilitar el cepillado dental. Conocer la evolución histórica del cepillo dental constituye el propósito de esta revisión. Se realizó una búsqueda exhaustiva retrospectiva automatizada en internet, utilizando el buscador Google. Para reunir la información necesaria se emplearon las herramientas para la comunicación asincrónica de gestores personales como Endnote, que facilitan el ordenamiento de las citas. Se consultaron artículos originales en revistas, informaciones en sitios web y blogs. No hubo restricciones en la selección de los materiales, ni por fecha, autores o estilos. Se revisaron textos que en sus páginas presentan referencias concernientes al tema de investigación. Consideramos que no es necesario utilizar cepillos de alta tecnología para la lograr la higiene dental. Aplicar una técnica adecuada y saber emplear el cepillo dental facilitará este proceso, para evitar enfermedades frecuentes causadas por la placa dentobacteriana (caries dentales y enfermedad periodontal, y así lograr por más tiempo la conservación dientes funcionales en la cavidad bucal.

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

Full Text Available El presente trabajo expone avances de conocimiento acerca de algunos impactos territoriales, de la exploración y explotación de hidrocarburos de reservorios no convencionales en la Cuenca Neuquina Argentina. Se enfocan los cambios recientes en el sistema de ciudades de la Confluencia Neuquina y en las tramas de empresas que integran la cadena de valor. Ellos se extienden asimismo a localidades rionegrinas asentadas en la Cuenca, extendida hasta el sur de la provincia de Mendoza y el oeste de las provincias de la Pampa y Río Negro. Se retoman debates teóricos sobre las funciones de las ciudades, el peso de la trayectoria y los fenómenos de aglomeración, los cambios que se generan como parte de redes y flujos en tiempos de la globalización; y las cuestiones de la gestión del conocimiento y las capacidades de innovación de las pequeñas y medianas empresas proveedoras de bienes y servicios a los hidrocarburos. Se revisan documentos, planes y programas públicos sobre la región y las relaciones proveedores/clientes en el upstream, y se reflexiona acerca de las tensiones que generan dichos procesos, y las perspectivas de transformación del sistema urbano regional en su actual fase de desarrollo. La evaluación de los cambios urbanos de las actividades relacionadas al upstream, y una amplia gama de servicios directos de distinta intensidad tecnológica, involucran factores regionales y locales en las distintas ciudades, acorde a su localización, funciones, trayectoria histórica regional y de las localidades, y sus posibilidades de integración y diversificación económica. En dicho sistema de organización, Neuquén capital es un centro abastecedor de servicios públicos y privados, sociales, personales y a empresas, de distinto grado de complejidad y alcance regional.

Full Text Available La erosión dental es la pérdida localizada, crónica y patológica de tejido duro dental. Ésta es causada por soluciones químicas las cuales entran en contacto con los dientes. La apariencia de los dientes erosionados es suave, sedosa y brillante, a veces mate, la superficie del esmalte tiene una ausencia de periquimatíes y esmalte intacto en el margen gingival. Se ha hipotetizado que la banda de esmalte preservado a lo largo del margen vestibular y lingual pudiera ser debido a que algunos remanentes de placa podían actuar como una barrera de difusión para los ácidos. Un diagnóstico temprano de este daño del tejido duro dental es de importancia clínica. El objetivo de este artículo es mostrar algunos aspectos básicos de erosión dental en términos de diagnóstico y epidemiología. Este documento enfatiza sobre factores de riesgo extrínsecos los cuales son discutidos con respecto a su relevancia para el desarrollo de erosión dental. Salud UIS 2011; 43 (2: 179-189Dental erosion is a pathologic, chronic, localized loss of dental hard tissue. It is caused by chemical solutions which come into contact with the teeth. The appearance of eroded teeth is smoothing, silky-glazed, sometimes dull, the enamel surface has an absence of perikymata and intact enamel on the gingival margin. It has been hypothesized that the preserved enamel band along the oral and facial gingival margin could be due to some plaque remnants could act as a diffusion barrier for acids. Early diagnosis of this damage of dental hard tissue is of clinical importance. The aim of this article is to show some basic aspects of dental erosion in terms of diagnosis and epidemiology.

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.

In the dental X-rays and mammography facilities, usually lead shielded walls as protective barriers are used. Lead is a good attenuator for X-rays, but has toxic properties and its cost is high. Mammography equipment s emit low-energy photons in the range of 25 keV to 35 keV, on current computers; the primary radiation beam is intercepted by the image receptor. Peri apical dental equipment s emit photons in the range of 50 to 90 keV, their filtration is fixed. These devices emit a collimated beam whose diameter is slightly larger than the diagonal dimension of a standard film of dental X-rays. When a dental x-ray is performed, the radiation beam is partially attenuated by the patient. Drywall is a material consisting of plasterboard between two cardboard layers, being its components gypsum and cellulose generally. It is used in construction for execution of interior walls, ceilings and wall coverings, could also serve as a replacement for lead as well as other materials. In this paper three drywall prototypes (Giplac), formed with 02, 04 and 06 drywall layers (13, 16 and 20 cm of thickness respectively) were tested as barriers against primary and secondary X-ray radiation that come from dental and mammography equipment s. The results show that the drywall prototype, 02 layers, efficiently attenuates the secondary radiation beam produced by conventional mammography equipment. And the prototype 04 and 06 layers, efficiently attenuates the primary radiation beam produced by peri apical dental equipment. (author)

Full Text Available La apariencia dental es considerada un componente de la belleza facial, que al ser restaurada por el odontólogo, podría influir con un efecto positivo en la valoración personal y la calidad de vida. El objetivo del estudio fue determinar la satisfacción general con la apariencia dental en estudiantes de las carreras de Artes Visuales y Diseño de Indumentaria del Instituto Superior de Arte de la Facultad de Arquitectura Diseño y Arte de la Universidad Nacional de Asunción, matriculados en el 2014. Se aplicó un cuestionario que contenía preguntas sobre datos demográficos, satisfacción con el aspecto dental general y con diversos aspectos dentales, así como también sobre el tratamiento estético deseado. La muestra quedó conformada por 108 estudiantes, que corresponde al 49,1% de la población. Se observó que el 48,2% se encontraba insatisfecho con el aspecto general de sus dientes, siendo los tratamientos de elección: blanqueamiento (63,9% y ortodoncia (47,2%. Los factores predisponentes a la insatisfacción fueron residir en Gran Asunción e interior del país y percibir sus dientes como desalineados. Por otro lado, favoreció la satisfacción el haberse sentirse a gusto con el color de sus dientes.

Full Text Available Un método sencillo de laboratorio reveló diferencias en el éxito de alimentación de Lutzomyia evansi, el vector de Leishmania chagasi en el norte de Colombia, cuando se alimentó sobre cinco especies de pequeños mamíferos de un foco endémico de leishmaniasis visceral, en los que éstos podrían actuar como reservorios. En cada ensayo, a 50 flebótomos hembra se les permitió alimentarse durante 30 minutos sobre un área similar de piel depilada de la pata posterior en 44 mamíferos. El número de flebótomos alimentados se comparó entre especies a través de un análisis de varianza y de la prueba de Tukey de comparaciones múltiples. Los flebótomos escasamente se alimentaron sobre Sciurus granatensis, una ardilla común en el área endémica que no se ha encontrado infectada con Leishmania chagasi. En otros dos mamíferos que hasta el presente han sido negativos para L. chagasi (Heteromys anomalus y Zygodontomys brevicauda, los flebótomos se alimentaron en bajos números. En cambio, los flebótomos se alimentaron en altas proporciones sobre Didelphis marsupialis y Proechimys canicollis, los dos mamíferos más abundantes en el área endémica y que se hallan infectados con L. chagasi. Los resultados aportaron evidencia adicional que estas dos especies de mamíferos silvestres serían una fuente de sangre común para los flebótomos y que, por lo tanto, pueden tener gran impacto sobre la transmisión de L. chagasi en el norte de Colombia.

Weaker dental enamel explains dental decay.

Vieira, Alexandre R; Gibson, Carolyn W; Deeley, Kathleen; Xue, Hui; Li, Yong

2015-01-01

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

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.

2015-01-01

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.

Mapeo cromático dental a partir de imágenes digitales

2015-11-01

Full Text Available El mapeo cromático dental es una técnica que consiste en la estimación de las características ópticas de la dentadura del paciente. Su objetivo es crear un mapa de tonalidades que facilite, al especialista, la elección de resinas o cerámicas a utilizar en la restauración de piezas dentales. Actualmente, el mapeo cromático se realiza comparando directamente la dentadura del paciente contra una guía de colores. Dicho procedimiento se ve afectado por diferentes factores como: condiciones ambientales, características del paciente, percepción del especialista, entre otras, lo que involucra un alto grado de subjetividad. En el presente trabajo se describe un método para el mapeo cromático dental a partir de imágenes digitales. El principal objetivo de esta propuesta es reducir la subjetividad en la selección de los materiales para la reconstrucción de piezas dentales, y en un futuro, desarrollar una herramienta que realice este trabajo automáticamente.

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

Fluorosis dental: no solo un problema estético Dental fluorosis: not only an aesthetic problem

Full Text Available Mientras la profesión estomatológica plantea que la fluorosis dental es solamente un problema estético y no un efecto de salud, esta declaración es una asunción y no un hecho. Ciertamente, la fluorosis dental representa un efecto tóxico en las células del diente, pero se pregunta si las células del diente son las únicas células en el cuerpo que son impactadas por este efecto. Motivados por lo controvertido del tema, se realiza una revisión bibliográfica con el objetivo fundamental de profundizar en los conocimientos teóricos y las características clínicas de esta afección que puede manifestarse tanto de formal local como general, y las consecuencias del uso inadecuado del flúor en el organismo humano. Se concluye que fluorosis es una enfermedad que no solo afecta las estructuras dentarias, y no puede ser enmarcada solamente pos los estomatólogos debido a las afecciones dentarias que puede producir, pues en muchas ocasiones es el primer signo de que la persona ha estado expuesta a niveles elevados de flúor.While the stomatological profession states that dental fluorosis is only an aesthetic problem and not a health effect, this declaration is an assumption and not a fact. Certainly, dental fluorosis represents a toxic effect in the tooth cells, but it is asked if the tooth cells are the only body cells impacted by this effect. Motivated by this controversial topic, a bibliographic review was made aimed mainly at going deep into the theoretical knowledge and the clinical characteristics of this affection that may manifest in a local or general way, and into the consequences of the inadequate use of fluor in the human organism. It was concluded that fluorosis is a disease that not only affects the dental structures and that it can not only be defined by the stomatologists due to the dental affections it may produce, since in many occasions it is the first sign that the person has been exposed to elevated levels of fluorine.

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 (ptobacco and did not perceive they had received enough training on intervening with patients on use of cigarettes 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.

2018-01-01

Although a link between dietary changes, caries, and dental development has been observed, the literature provides little insight about this relationship. The aim of our study was to investigate the association between dental caries and dental development in a clinical sample of Albanian children and adolescents. In total, 118 children and adolescents, born between 1995 and 2004 and aged 6–15 years, were included. Dental caries in the deciduous dentition was assessed using the Decayed, Filled Teeth (dft) index and dental caries in the permanent dentition was assessed using the Decayed, Missing, Filled Teeth (DMFT) index. Dental development during the permanent dentition was determined using the Demirjian method. Linear and ordinal regression models were applied to analyze the associations of dental caries with dental age and developmental stages of each left mandibular tooth. Dental caries in the deciduous dentition, estimated as a median dft of 2.0 (90% range, 0.0–9.1), was significantly associated with lower dental age (β = -0.21; 90% CI: -0.29, -0.12) and with delayed development of the canine, both premolars, and the second molar. Untreated dental caries (dt) was associated with lower dental age (β = -0.19; 90% CI: -0.28, -0.10). Dental caries in the permanent dentition, estimated as a median DMFT of 1.0 (90% range, 0.0–8.0), was not significantly associated with dental age (β = 0.05; 90% CI: -0.04, 0.14). However, the DMFT was associated with the advanced stages of development of both premolars and the second molar. The untreated dental caries in the deciduous dentition delays the development of permanent teeth. PMID:29659350

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.

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

Objectives 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. Methods We derived county-level (n = 364) data on demographic, socio-economic 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 Resource 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). Results 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. Conclusions 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

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.

Medina, Aida Carolina; Pozo, Rodrigo Del; de Cedres, Lucila Blanco

Dental agenesis is the most common developmental anomaly in humans, frequently associated with disorders in dental development and maturation. The purpose of this study is to determine radiographic variations in dental maturation in a group of Venezuelan children with dental agenesis. 1,188 panoramic radiographs, from healthy patients ages 5 to 12 years old were studied for agenesis of permanent teeth. Dental maturation was assessed by relative eruption and dental age according to Nolla, comparing children affected with dental agenesis to a stratified control group selected from the same population, excluding children with premature loss of primary teeth in the left quadrants and unclear radiographs. Descriptive analysis, and differences between means and medians (Student t test, Kruskall-Wallis p=0.05) were performed. Medians for Nolla stages were similar between groups, with delay in tooth formation in the agenesis group for second molars (p<0.05) and maxillary lateral incisors and second premolars. Dental age was significantly underestimated for both groups, -0.89 (±0.78) for the control group and -1.20 (±0.95) for the study group. Tooth eruption was similar between groups. Dental age was significantly delayed in Venezuelan children with dental agenesis, with variable significance for tooth formation of studied teeth.

The objective was to examine the relationship between dental pain (and its sequelae), and the extent of restorative care provided for primary molars, amongst children who regularly attend a general dental practitioner. A retrospective review of the clinical case notes of 677 children with caries who attended 50 general dental practitioners on a regular basis. Analyses were performed at the subject level. Logistic regression models were fitted for the dependent variables whether or not pain, a dental extraction for pain or sepsis and a course of antibiotics was recorded, after taking into account the proportion of carious teeth that were restored, the total number of carious teeth, the age caries was first recorded, gender and the clustering of the subjects within dental practices. Almost half of the children in the study (48%) were recorded as having at least one episode of pain. Total decay experience in the primary molars was a significant predictor of pain, extraction due to pain or sepsis and prescription of antibiotics. There was no significant association between the proportion of carious teeth restored and each of the three dependent variables. For those children who regularly attend their general dental practitioner and who have decay in their primary molars, dental pain is a common finding. Total decay experience in primary molars is the principal predictor of pain, extraction due to pain and the need for antibiotics, whilst the level of restorative care in the primary dentition is less important. In order to reduce the incidence of dental pain in young children, effective methods of preventing caries at the individual and public health levels need to be expanded.

General anesthesia has been widely used in pediatric dentistry in recent years. However, there remain concerns about potential postoperative dental morbidity. The goal of this study was to identify the frequency of postoperative dental morbidity and factors associated with such morbidity in children. From March 2012 to February 2013, physically and mentally healthy children receiving dental treatment under general anesthesia at the Department of Pediatric Dentistry of the Chang Gung Memorial Hospital in Taiwan were recruited. This was a prospective and observational study with different time evaluations based on structured questionnaires and interviews. Information on the patient demographics, anesthesia and dental treatment performed, and postoperative dental morbidity was collected and analyzed. Correlations between the study variables and postoperative morbidity were analyzed based on the Pearson's chi-square test. Correlations between the study variables and the scale of postoperative dental pain were analyzed using the Mann-Whitney U test. Fifty-six pediatric patients participated in this study, with an average age of 3.34 ± 1.66 years (ranging from 1 to 8 years). Eighty-two percent of study participants reported postoperative dental pain, and 23% experienced postoperative dental bleeding. Both dental pain and bleeding subsided 3 days after the surgery. Dental pain was significantly associated with the total number of teeth treated, while dental bleeding, with the presence of teeth extracted. Patients' gender, age, preoperative dental pain, ASA classification, anesthesia time, and duration of the operation were not associated with postoperative dental morbidity. Dental pain was a more common postoperative dental morbidity than bleeding. The periods when parents reported more pain in their children were the day of the operation (immediately after the procedure) followed by 1 day and 3 days after the treatment.

Purpose: To demonstrate the usefulness of Dental-MRT for imaging of anatomic and pathologic conditions of the mandible and maxilla. Methods: Seven healthy volunteers, 5 patients with pulpitis, 9 patients with dentigerous cysts, 5 patients after tooth transplantation and 12 patients with atrophic mandibles were evaluated. Studies of the jaws using axial T1- and T2-weighted gradient echo and spin echo sequences in 2D and 3D technique have been to performed. The acquired images were reconstructed with a standard dental software package on a workstation as panoramic and cross sectional views of the mandible or maxilla. Results: The entire maxilla and mandibula, teeth, dental pulp and the content of the mandibular canal were well depicted. Patients with inflammatory disease of the pulp chamber demonstrate bone marrow edema in the periapical region. Dentigerous cysts and their relation to the surrounding structures are clearly shown. After contrast media application marked enhancement of the dental pulp can be found. Conclusion: Dental-MRT provides a valuable tool for visualization and detection of dental diseases. (orig.) [de

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.

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.

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

Poorterman, J H G; Dikkes, B T; Brand, H S

2010-08-01

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.

Epidemiología molecular de la rabia urbana en Colombia, 1994-2004. La rabia en ecosistemas silvestres como amenaza para la población humana

En Colombia la rabia ocurre en dos ciclos epidemiológicos principales: la rabia urbana con el perro como principal reservorio y transmisor principalmente a humanos, y la rabia silvestre con especies animales de la vida silvestre como los quirópteros y zorros entre otros, como reservorios y transmisores principalmente a especies ganaderas y eventualmente a humanos que se convierten en víctimas accidentales. Durante los últimos años la rabia silvestre en Colombia ha cobrado mayor relevancia como problema de salud pública que la rabia urbana, a juzgar por el número de víctimas humanas. Con el fin de perfeccionar el diagnóstico y la tipificación del virus de la rabia en Colombia, el Laboratorio Nacional de Referencia del Instituto Nacional de Salud estandarizó técnicas para amplificar y secuenciar un fragmento de ADN complementario (cADN a una fracción de 902 nucleótidos seleccionados del ARN del virus, con el fin de adelantar estudios de epidemiología molecular. La fracción mencionada contiene secuencias que codifican para los aminoácidos 447-525 de la glicoproteína y 1-35 de la proteína L. Además contiene la región intergénica no codificante conocida como Pseudogen Psi.

Full Text Available En las últimas décadas, numerosas investigaciones se han dedicado al estudio de los mecanismos potenciales implicados en el desarrollo de la caries dental y su prevención, sin embargo, a pesar de haber disminuido gradualmente el índice de caries en la población, son muchos los pacientes que necesitan tratarse la caries dental, tal es así que continuamente se están utilizando diferentes materiales en la búsqueda de aquel que ante una agresión a la pulpa, ayude a una respuesta biológica de la misma, conservando de esta forma su integridad. De ahí la importancia de la actividad de la fosfatasa alcalina de la pulpa en el proceso carioso, como una reacción ante el hidróxido de calcio que continuamente se está usando en toda la red docente-asistencial del país. Se seleccionaron 50 dientes monorradiculares, con pulpa viva y con caries de segundo, tercer y cuarto grado y 50 dientes sanos de pacientes de diferentes edades. Se extrajo la pulpa de cada diente y se realizaron improntas (3 por cada muestra, una de las cuales se procesó para obtener orientación morfológica, y las otras 2 para valorar la actividad de la fosfatasa alcalina. Para esto se utilizaron 2 métodos: el de calcio cobalto y el de alpha naftol fosfato de Gomori. Como resultado, se obtuvo que la pulpa tiene más actividad enzimática en caries profunda y que la edad del paciente no determina el aumento o disminución de dicha actividad.In the last decades, numerous investigations have been made on the study of potential mechanisms involved in the development of dental caries and their prevention. However, in spite of the gradual reduction of dental caries in the population, a lot of patients need to have their dental caries treated and different materials are continuously used searching for one that before the aggression to the pulp helps it to give a biological response, conserving this way its integrity. That's why the activity of the alkaline phosphatase of the pulp

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.

2016-01-01

Summary Background 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. Objective 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. Methods 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. Results 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). Conclusions On average, a dentist spent far less time than dental assistants and dental hygienists in data recording within the EDR. PMID:27437058

This cross sectional study was performed to evaluate dental ages and incidence of dental anomalies in children treated for acute lymphoblastic leukemia (ALL). A total of 25 ALL patient who passed at least 2 years of chemotherapy and 25 healthy sex and age matched children were evaluated. Dental age as well as dental anomalies in shape, size, number, and structure was recorded based on their panoramic radiographies which were taken for dental purposes. The number of dental anomalies significantly increased in ALL treated children. Seven ALL cases (28%) in compression to only one (4%) in control group had at least one dental anomaly. However, there was neither statistically significant differences between the mean of dental (p=0.32) and chronologic age (p=0.12) in both groups, nor between dental age of cases and control group (p=0.62).The age at the onset of treatment as well as treatment durations has not affected dental age and the incidence of dental anomalies significantly (pdental anomaly. Dental age, maturity, and development process however seems to be independent from chemotherapy.

This article describes recent trends in dental visits and private dental insurance in the United States. This study is based on the analyses of data regarding dental visits and private dental insurance among the population 2 years of age or older from the 1989 and 1999 National Health Interview Surveys. Overall, the percentage of the population with a dental visit rose from 57.2 percent in 1989 to 64.1 percent in 1999, while the percentage with private dental insurance fell from 40.5 percent to 35.2 percent. Although a higher percentage of people with private dental insurance reported having a dental visit than did those without private dental insurance in both years, the increase from 1989 to 1999 in the percentage of those with a visit was larger among the uninsured. If this trend persists, a smaller portion of practicing dentist's clientele will be insured. This may affect demand for services, as well as front office operations.

Singhal, Astha; Damiano, Peter; Sabik, Lindsay

2017-04-01

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

Armfield, Jason M; Ketting, Manon

2015-09-01

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).

The aim of this study was to evaluate the factors influencing the satisfaction of dental appearance and attitude toward treatments to improve dental esthetics among patients attending a dental teaching center. A questionnaire was used to collect data of four background variables among 450 patients attended a dental teaching center in the city of Irbid in Jordan. The questionnaire enclosed self-reported questions about the appearance of anterior teeth, received esthetic treatment and desired treatment for improving esthetics. Descriptive, multiple logistic regression and Chi-square tests were used for data analysis (p ≤ 0.05). The 450 participants consisted of (66.2%) male and (33.8%) female. Of these, 69.3% were satisfied with their dental appearance and 58.0% with the color of their teeth. Esthetic restorations were the most received treatment (39.8%) and whitening of teeth was the most desired treatment (55.3%). The patients' satisfaction with dental appearance was influenced by teeth color, crowding and receiving whitening (p < 0.05. r = 0.561, r(2) = 0.315). The most desired esthetic treatments influenced by the satisfaction with dental appearance were esthetic restorations and orthodontics (p < 0.05. r = 0.223, r(2) = 0.05). Significantly more female reported having esthetic restorations and orthodontics (p = 0.008, 0.000) and desired to have orthodontic, crowns or veneers and esthetic restorations (p = 0.000, 0.015, 0.028). Satisfaction with dental appearance was affected by teeth color, feeling teeth are crowded, desire for esthetic restorations and orthodontic treatment. A high percentage of patients were not satisfied with the color of their teeth. Recognizing the factors that affect patients' satisfaction with their present dental appearance and attitude toward treatments to improve dental esthetic can guide clinicians to strategies to improve esthetics.

Purpose: To demonstrate the usefulness of Dental-MRT for imaging of anatomic and pathologic conditions of the mandible and maxilla. Methods: Seven healthy volunteers, 5 patients with pulpitis, 9 patients with dentigerous cysts, 5 patients after tooth transplantation and 12 patients with atrophic mandibles were evaluated. Studies of the jaws using axial T1- and T2-weighted gradient echo and spin echo sequences in 2D and 3D technique have been to performed. The acquired images were reconstructed with a standard dental software package on a workstation as panoramic and cross sectional views of the mandible or maxilla. Results: The entire maxilla and mandibula, teeth, dental pulp and the content of the mandibular canal were well depicted. Patients with inflammatory disease of the pulp chamber demonstrate bone marrow edema in the periapical region. Dentigerous cysts and their relation to the surrounding structures are clearly shown. After contrast media application marked enhancement of the dental pulp can be found. Conclusion: Dental-MRT provides a valuable tool for visualization and detection of dental diseases. (orig.)

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.

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

All children in Sweden are entitled to regular, free dental care up to 20 years of age. While dental caries generally continues to decline, still there is a pronounced skewness in caries prevalence. Furthermore, the reported increase in dental erosion in young adults is cause for concern. The aim was to study the prevalence of dental caries and dental erosion in a cohort of Swedish 20 year-olds, with special reference to the influence of previous caries experience and lifestyle as well as parental, socioeconomic and psychosocial factors. The study was prospective, longitudinal and cross-sectional in design and based on registration of caries lesions, dental erosion, body adiposity status, saliva sampling, interviews, and questionnaires at 20 years of age. Data were available for the same cohort at 1, 3, 6 and 15 years of age. 499 subjects (74 percent of the original cohort) were included. Five individuals were subsequently excluded, leaving a final sample of 494. 74 percent of the subjects had initial and/or manifest caries lesions and/or restorations. The mean number of DimFS was 5.8 and the mean number of DmFS on occlusal surfaces of molars was 1.1. There was a strong relationship between caries activity at 3 and 6 years of age and approximal caries prevalence in premolars and molars at 20 years of age. Overweight/obese individuals had significantly higher caries prevalence than normal weight individuals. Parental, socioeconomic and psychosocial factors during infancy were related to approximal caries at age 20. Dental erosion was found in 75 percent of the individuals: 18 percent of these had extensive erosion. There was a significant association between caries and dental erosion. A relationship was found between dental erosion and lifestyle factors and overweight/obesity. There is a strong relationship between caries prevalence at age 20 and caries experience in early childhood. Young adults show a high prevalence of dental erosion, but the severity is

Manejo clínico de la resorción dental interna utilizando agregad o trióxido mineral como material de obturación intracanal

There is a great need for leaders in the dental profession. As technological advances make our world smaller and our lives faster and more complex, we as a profession face challenges and opportunities that are evolving. Many of the changes in the scope and mode of practice will require new and different approaches. Meeting these challenges will require changes in how we as dental professionals do business; interact with our patients, other stakeholders, and health care providers; and educate our future colleagues. The purposeful incorporation of leadership education into dental and dental hygiene curricula represents an important departure from existing paradigms-but will help prepare our students to address these challenges. This article provides an overview of the development of a Scholars Program in Dental Leadership (SPDL) at the University of Michigan School of Dentistry. Our aim for the program is to create a learning environment that fosters leadership development, so that students are prepared and motivated to assume leadership positions in the profession and their communities.

The purpose of this study was to determine the methods dental practitioners in the United Arab Emirates (UAE) use to communicate cast removable dental prosthesis (RDP) design to dental laboratories; identify common practices taken by dentists/dental technicians prior to fabrication of RDP framework; and seek out dental technicians' attitudes toward their role in RDP design decisions. All dental laboratories (n = 28) listed in a local telephone directory were invited to complete a questionnaire through a face-to-face interview. They were also requested to examine RDP cases fabricated in the past 2 months and identify steps taken by dentists/dental technicians prior to fabrication of the framework. Descriptive statistics were used to report frequencies and percentages. Twenty-one (75%) dental laboratories agreed to participate, out of which 19 had the facilities to fabricate chrome-cobalt RDPs. Cast RDPs comprised approximately 4.04% (±2.67) of services provided. A reported 84.2% of dentists frequently communicate through generic lab script, with 89.5% rarely/never giving details regarding RDP design. While 52.6% of labs agree/strongly agree that it is the dentist's responsibility to decide the final RDP design, 94.7% agree/strongly agree that dentists should depend on dental technicians for design-making decisions. A total of 19 RDP cases were reviewed. All 19 were surveyed and designed by dental technicians but received dentist approval of design prior to fabrication. Thirteen (68.4%) had rest-seat preparations done by dentists after approval, and new impressions sent to the lab. No other tooth modifications were noted. The responsibility of RDP design appeared to be largely delegated to dental technicians. Importance of tooth modifications seemed to be undervalued and not completed prior to framework fabrication. © 2012 by the American College of Prosthodontists.

Study Design: The questions were structured using adobe forms central online software, regarding the user-friendliness of pediatric dental chair vs. traditional adult dental chair available in the market. Results: Our result shows that out of 337 respondents, 79% worked on pediatric dental chair, whereas 21% had no experience of it. Of these 79% pediatric dentist, 48% preferred pediatric dental chair. But pediatric dental problem still has certain disadvantages like higher cost, leg space problem, lower availability, etc. Conclusion: During the research it was found that ergonomics and usability issues were the main problems. Thus, pediatric dental chair is not so popular in the current scenario. This study allowed for general ideas for the improvement of dental chairs and thus improved dental chair would fill the gap in the current scenario.

Organisational aspects of dental practices: do dental students think like patients or like general dental practitioners?

In view of transparency in health care, the widespread desire for more patient-centred care, and in an attempt to facilitate educational programmes that effectively respond to these changes, two research questions are formulated: (i) How do dental students rate the importance of various organisational aspects of dental practices compared with dental patients and general dental practitioners (GDPs), and what prescripts, defined as specific operational responsibilities of GDPs in these matters, do dental students propose? and (ii) In doing so, do students resemble patients or GDPs? In two survey studies, dental students (n = 198), patients (n = 3127) and GDPs (n = 303) were asked to rate by questionnaire the importance of 41 organisational aspects of a general dental practice and proposed specific operational responsibilities ('prescripts'). Seven of 41 aspects were rated as important by the majority of the students. Although in a different rank order, three aspects were predominantly selected by all three groups: continuing education, accessibility by telephone and Dutch-speaking GDP. For most aspects, significant differences were found between the prescripts proposed by students and those proposed by patients, and few differences were found between students and GDPs. The findings do not permit the general conclusion that the views of dental students resemble those of patients or GPDs. Looking at the overall rank order, the three respondent groups showed a great resemblance although significant differences were found for specific aspects. With regard to the proposed prescripts, students showed realistic views and the majority wants to participate in continuing education and work with protocols and guidelines. In this, they tend to resemble GDPs more than they resemble patients. © 2012 John Wiley & Sons A/S.

This paper provides information about Peru's dental history and dental school system, including the curriculum and dental licensure. With the increase in the number of dental schools in Peru, the number of dentists is also increasing. Until 1965, Peru had only three dental schools; currently, there are 14. Four of these dental schools are public, and ten are private. A five- or six-year dental program leads to the B.D.S. degree. After successful completion of a thesis defense or competency examination, the D.D.S. degree is awarded. The D.D.S. is mandatory for practicing dentistry in Peru. Currently, there are approximately 14,000 active dentists, with a dentist-patient ratio of approximately 1:2,000.

U.S. Dental School Deans’ Perceptions of the Rising Cost of Dental Education and Borrowing Pressures on Dental Students: Report of Survey Results.

2015-06-01

This report presents findings from a survey of U.S. dental school deans designed to capture their perceptions regarding the rising cost of dental education and its impact on borrowing by dental students to finance their education. The survey included questions about factors influencing the cost of dental education, concerns about dental student borrowing, and financial awareness resources for students. The survey was distributed to the deans of all 63 U.S. dental schools in January 2013; 42 deans responded, for a 67% response rate. The results indicate that, according to the responding deans, new clinical technologies, technology costs, and central university taxes are the main factors that contribute to the increasing cost of dental education. Coupled with reduced state appropriations at public dental schools and declines in private giving at all dental schools, dental school deans face a perplexing set of financial management challenges. Tuition and fees are a primary source of revenue for all dental schools; however, many deans do not have total control over the cost of attending their schools since tuition and fees are often tied to mandates and policies from the parent university and the state legislature. The findings of this study indicate that U.S. dental school deans are aware of and concerned about the impact of increases in tuition and fees on dental student debt and that they are using a variety of strategies to address the growth in dental student borrowing.

Barriers and Drawbacks of the Assessment of Dental Fear, Dental Anxiety and Dental Phobia in Children: A Critical Literature Review.

Asl, Aminabadi Naser; Shokravi, Marzieh; Jamali, Zahra; Shirazi, Sajjad

Dental anxiety, fear and phobia have different etiology, response patterns, time courses, and intensities that justify a clear distinction between these constructs. Differentiation of dental anxiety, fear or phobia in practice is a critical prerequisite for developing and implementing effective treatment for children. The aim of this study was to investigate whether current researches in the pediatric dentistry appropriately discriminate the central construct of dental anxiety, fear and phobia. We also highlighted the specific methodological issues in the assessment of these issues in pediatric dentistry. A systematic search was conducted in Pubmed/medline and Scopus for articles which assessed dental anxiety, fear or phobia in children. 104 research papers were included in the review that had made a distinction between dental anxiety, fear and phobia and had not used them interchangeably. Only five studies used different clinical measures or cut-offs to discriminate between dental anxiety, fear and phobia. The dental literature appears unable to capture and also measure the multi-sided construct of dental anxiety, fear and phobia and, therefore, there was a tendency to use them interchangeably.

Home patients have few chances for going out, so communication with their family means a lot. Talking and eating are particular pleasures. Therefore, oral and dental health and oral and dental support are very important for home patients. A dental hygienist from our clinic visits and offers oral and dental health (oral care) and oral and dental support (oral rehabilitation) to home patients as part of a care plan with home care nurses. Moreover, as general conditions are closely related with oral function, maintaining oral and dental health and regular oral and dental support are very important in order to improve the quality of life (QOL) of home patients.

2017-10-01

Purpose: Many states are exploring alternative provider models and examining the role of the dental hygienist to address access to care challenges as the United States continues to face increasing demands for oral healthcare services. The purpose of this study was to assess dental hygienists' opinions in the state of Oregon regarding the current limitations of dental hygienists' scope of practice, perceived need for a mid-level provider in Oregon, and personal interest in becoming a mid-level provider. Methods: In December 2013 a survey was mailed to a sample of 1,231 dental hygienists registered in Oregon representing 30% of the licentiates. All licentiates holding expanded practice permits (EPP) were included in the sample (n=351). The following categories were included in the 32-question survey: scope of practice, mid-level provider, current practice, and demographics. Results: A total of 440 surveys were returned for a response rate of 36%. Of the EPP holders, 51% responded to the survey. Over half of respondents (59%) believe that a mid-level provider is needed in the state. Respondents holding membership in the American Dental Hygienists' Association, as well as EPP holders, were significantly more likely to respond that a mid-level dental provider was needed in the state (plevel provider was introduced in Oregon, the new provider should be a registered dental hygienist model. Forty-three percent (n=186) of respondents were interested in becoming mid-level providers and 47% (n=203) of respondents believed that the minimum education for a mid-level provider should be a bachelor's degree. The majority, 74% (n=137), of those interested in becoming a mid-level provider indicated a preference in completing their education through online teaching combined with a clinical internship. Conclusion: There is strong support from dental hygienists in Oregon that a need exists for a mid-level dental provider and that this provider model should be dental hygiene based

Policy has recently changed on provision of dental general anaesthetic services in England. The aim of this study was to investigate general dental practitioners' views about dental general anaesthetics, the reduction in its availability and the impact on care of children with toothache. Qualitative study using semi-structured interviews and clinical case scenarios. General dental practitioners providing NHS services in the North West of England. 93 general dental practitioners were interviewed and 91 answered a clinical case scenario about the care they would provide for a 7-year-old child with multiple decayed teeth presenting with toothache. Scenario responses showed variation; 8% would immediately refer for general anaesthesia, 25% would initially prescribe antibiotics, but the majority would attempt to either restore or extract the tooth causing pain. Interview responses also demonstrated variation in care, however most dentists agree general anaesthesia has a role for nervous children but only refer as a last resort. The responses indicated an increase in inequalities, and that access to services did not match population needs, leaving some children waiting in pain. Most general dental practitioners support moving dental general anaesthesia into hospitals but some believe that it has widened health inequalities and there is also a problem associated with variation in treatment provision. Additional general anaesthetic services in some areas with high levels of tooth decay are needed and evidence based guidelines about caring for children with toothache are required.

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

To examine the relationship between self-reported parental rearing style, parent's assessment of their child's dental anxiety and the dental history of children. Parents of primary school children were asked to complete questionnaires about their parenting style, using four different questionnaires. Parents also completed the Child Fear Survey Schedule Dental Subscale (CFSS-DS) on behalf of their child and a questionnaire about the dental history of their child. 454 interview forms were available for analysis. Minor associations were found between dental anxiety and parenting style. Anxious parents were more permissive and less restrictive in their parenting style. Parents of children who did not visit their dentist for regular check-ups reported more laxness and less restrictiveness. Children who had a cavity at the time of investigation, children who had suffered from toothache in the past and children who did not have a nice and friendly dentist reported more dental anxiety. No clear associations between parenting style and dental anxiety were found. Known causes of dental anxiety were confirmed.

Scarbecz, Mark; Ross, Judith A

2002-08-01

Women's role in the field of dentistry has historically been limited to the dental auxiliary fields, rather than that of D.D.S. or D.M.D. Today, women are nearly 38 percent of U.S. dental school students and 14 percent of active practitioners. The slow(er) influx of women into dentistry has been little studied by dental educators. During the 2000-01 academic year, we conducted a survey of first-year dental students at a sample of publicly funded U.S. dental schools. The purpose of the survey was to assess gender differences in motives for pursuing a dental career. The data show that male dental students rate self-employment and business-related motives as more important, while female dental students rate people-oriented motives more highly. Factor analysis revealed four distinct clusters of motives for pursuing a dental career: a financial motive, a business-oriented motive, a people-oriented or caring motive, and a flexibility motive. Women scored significantly higher than men on the caring factor, whereas the reverse was true on the business factor. Male and female students rated financial and flexibility motives equally. The implications of the results for attracting students to the profession of dentistry are discussed.

The purposes of this research were to investigate factors influencing patients' satisfaction with their present dental esthetic, received previous dental treatments on anterior teeth and basic treatments that they wanted to undergo to improve their dental appearance. A total of 1014 patients who attended a dental school in a major city in Turkey participated in the study. The participants were surveyed with a questionnaire containing questions about gender, age, education level, self-reported tooth appearance, received previous dental treatments on anterior teeth and desired basic esthetic dental treatments. Statistical analysis of the verifying data was made with descriptive statistics, chi2 test and multiple logistic regression analyses. According to the analyses of the verifying data, 55.1% of the patients were dissatisfied with the color of their teeth, 42.7% with dental appearance, 29.9% with crowding of anterior teeth, 23.3% were hiding teeth while smiling, 16.1% had non-esthetic restorations and 11.9% thought that their anterior teeth were protruding. Esthetic restoration was found to be the most-performed treatment recently (29.0%) and whitening of teeth was the most-desired dental treatment (49.0%). Gender, age and education level had an effect on satisfaction and received previous and desired dental treatments for improvement of esthetics. Many of the Turkish patients surveyed in the study were dissatisfied and desired the improvement of dental esthetics. Therefore, dentists should consider this as an important dimension in their practice.

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.

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

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 anxiety of patients is a common feature of the everyday experience of dental practice. This article advocates the use of regular assessment of this psychological construct to assist in patient management. Various tools, such as the Modified Dental Anxiety Scale (MDAS), are available to monitor dental anxiety that are quick to complete and easy to interpret. Patient burden is low. A new mobile phone assessment system (DENTANX) is being developed for distribution. This application and other psychological interventions are being investigated to assist patients to receive dental care routinely. Clinical relevance: This article provides evidence and expert opinion on the worth of regular dental anxiety assessment in dental practice using structured tools, such as the Modified Dental Anxiety Scale, and consideration of psychological intervention development.

Three-dimensional volume data set is useful for diagnosis in dental treatments. However, to obtain three-dimensional images of a dental arch in general dental clinics is difficult. In this paper, we propose a method to reconstruct pseudo three-dimensional dental images from a dental panoramic radiograph and a tooth surface shape which can be obtained from three dimensional shape measurement of a dental impression. The proposed method finds an appropriate curved surface on which the dental panoramic radiograph is mapped by comparing a virtual panoramic image made from a tooth surface shape to a real panoramic radiograph. The developed pseudo three-dimensional dental images give clear impression of patient's dental condition. (author)

History of dental hygiene research.

Science.gov (United States)

Bowen, Denise M

2013-01-01

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

[Correction made on 21 March 2014, after first online publication: The sentence 'Data on elderly's dental service are scarce, although increased use is seen and more teeth are present in this age group.' was removed.] A cross-sectional study of all aged 64-65 (n = 37 234) who received a dental examination in 2009 was conducted. Clinical data comprised dental services received under the National Health Insurance reimbursement scheme, dental status and DMFT. Geographical, socio-demographic and socioeconomic data derived from public registers. Almost all received restorations, while periodontal treatment was received by dental services was dominated by periodontal services. Periodontal services were most prevalent in the capital and the most affluent areas. Relatively more extractions were related to low income and persons in least affluent areas. Total number of services was highest among women, persons with ≥20 teeth, persons living in the capital, and where the ratio user per dentist was low. For future planning of dental care for elderly, dental status, geographical and social area-based factors and to some degree gender, income, and education must be taken into consideration as all these factors seem to influence the future demand for dental services. © 2014 John Wiley & Sons A/S and The Gerodontology Association.

India faces an acute shortage of health personnel. Together with inequalities in distribution of health workers, dental health workers also become a part contributing to it impeding the progress towards achievement of the Millennium Development Goals. To assess dental health-workforce distribution, identify inequalities in dental health-workers provision and report the impact of this mal distribution in India. Situational analysis done by using the primary data from the records of Dental Council of India. In India, 0.088% of dental health worker per 1000 population exists. Inequalities in the distribution of dentists exist in India. Certain states are experiencing an acute shortage of dental health personnel whereas certain cities are over fledged with dentists like Karnataka, Maharastra, Tamilnadu being states with high concentration & Jharkhand, Rajasthan, Uttaranchal being the least. Although the production of health workers has expanded greatly in recent years by increase in number of dental colleges the problems of imbalances in their distribution persist. In the race of increasing dentist population ratio in total, inequitable distribution of appropriately trained, motivated and supported dentists gives a mere feel of saturation in jobs making youngsters to not to choose dentistry as a career giving an alarm.

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.

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.

Entrepreneurship in continuing dental education: a dental school perspective.

Science.gov (United States)

Liberto, Vincent N

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.

This study investigates student and stakeholder perceptions of the role of the dental hygienist in Nepal. The impact of these perceptions on the professionalization of dental hygienists is described whilst exploring the consequences for oral health workforce planning. Dentistry and dental hygiene students from one dental college in Nepal were asked to complete an anonymous questionnaire; 171 students returned the questionnaire containing a mix of forced response and open-ended items. Quantitative data were analysed using SPSS ® 22. These data were complemented with qualitative information from survey open questions and from semi-structured interviews with key informants from several relevant organizations. Qualitative data were manually analysed and coded. Data were triangulated to contextualize quantitative data. A high level of positive regard for the role of the dental hygienist in Nepal was evident amongst dentistry and dental hygiene students in this college. Both groups believe that the dental hygienist can play a major role in raising oral health awareness in Nepal. The scope of practice of the dental hygienist was unclear with issues surrounding the scope of practice and reports of illegal practice by dental hygienists. Significant differences (P dental hygiene and dentistry students in relation to their opinion regarding independent practice and the need of supervision by a dentist. Supervision of the dental hygienist by dentists and issues surrounding the scope of practice are polarizing the relationship between dentists, dental hygienists and the relevant professional organizations. This could hinder cooperation between these oral health professionals and might lead to underutilization of the dental hygienist. To improve the understanding about the roles of each oral health professional, establishing functional relationships and intraprofessional education involving dentistry and dental hygiene students needs to be introduced. This will benefit the

Nikhil Ahuja

2014-01-01

Full Text Available Background and Objectives: Preventive approach in dental practice has been cited as a reason for the decline in oral diseases and as a predominant part of the service-mix of dental practices in the future. Dental faculty′s knowledge and attitude toward prevention are important, since they have exceptionally important direct and indirect roles in shaping student′s preventive orientation and also potentially influencing their patient′s ability to take care of their teeth. Thus, this study was conducted to assess knowledge and attitudes toward preventive dental care among dental faculties and their relation to demographic and professional characteristics. Materials and Methods: A cross-sectional study was conducted among dental faculties in Bangalore city. Of 17 dental colleges, 4 were selected by simple random sampling. A total of 218 dental faculties was individually asked to complete a pretested questionnaire. The questionnaire requested information on dental faculty′s demographic and professional characteristics and their knowledge and attitudes toward preventive dental care. Descriptive, Chi-square tests, and ANOVA were used to analyze the data. Results: The highest knowledge was seen among dental faculties regarding prevention of malocclusion (3.51 ± 1.02 followed by oral cancer (2.95 ± 1.09 and periodontal diseases (2.86 ± 1.02. The least knowledge was seen for the prevention of caries (2.63 ± 1.35. The most positive attitudes regarding preventive dentistry was characterized as being essential (6.34 ± 1.05, useful (6.32 ± 1.07 and valuable (6.27 ± 1.00. Statistically significant differences were found in relation to knowledge and attitudes for all demographic and professional characteristics except for gender and Department of Teaching. Conclusion: Dental faculty seems to have differing levels of knowledge regarding oral diseases with positive attitudes seen regarding preventive dentistry. Continuing education activities and

Regenerative medicine in dental and oral tissues: Dental pulp mesenchymal stem cell

Directory of Open Access Journals (Sweden)

Janti Sudiono

2017-08-01

Full Text Available Background. Regenerative medicine is a new therapeutic modality using cell, stem cell and tissue engineering technologies. Purpose. To describe the regenerative capacity of dental pulp mesenchymal stem cell. Review. In dentistry, stem cell and tissue engineering technologies develop incredibly and attract great interest, due to the capacity to facilitate innovation in dental material and regeneration of dental and oral tissues. Mesenchymal stem cells derived from dental pulp, periodontal ligament and dental follicle, can be isolated, cultured and differentiated into various cells, so that can be useful for regeneration of dental, nerves, periodontal and bone tissues. Tissue engineering is a technology in reconstructive biology, which utilizes mechanical, cellular, or biological mediators to facilitate regeneration or reconstruction of a particular tissue. The multipotency, high proliferation rates and accessibility, make dental pulp as an attractive source of mesenchymal stem cells for tissue regeneration. Revitalized dental pulp and continued root development is the focus of regenerative endodontic while biological techniques that can restore lost alveolar bone, periodontal ligament, and root cementum is the focus of regenerative periodontic. Conclucion. Dentin-derived morphogens such as BMP are known to be involved in the regulation of odontogenesis. The multipotency and angiogenic capacity of DPSCs as the regenerative capacity of human dentin / pulp complex indicated that dental pulp may contain progenitors that are responsible for dentin repair. The human periodontal ligament is a viable alternative source for possible primitive precursors to be used in stem cell therapy.

Dental anxiety and personality: investigating the relationship between dental anxiety and self-consciousness.

Science.gov (United States)

Economou, George C

2003-09-01

This study investigated whether personality plays a role in a condition called dental anxiety. Specifically, the study examined the relationship between dental anxiety (the negative response to the stress elicited from a dental interaction) and self-consciousness (the tendency to evaluate aspects of oneself that are subject to private and public display). The purpose of this study was to identify the characteristics possessed by dentally anxious individuals who face potential health risks because of their avoidance. Sixty York University undergraduate students were recruited by convenience sampling to participate. These subjects completed Corah's Dental Anxiety Scale and the Self-Consciousness Scale. The Self-Consciousness Scale consists of three subscales, including private self-consciousness, public self-consciousness, and social anxiety. Results indicated an 0.54 significant correlation between dental anxiety and self-consciousness. The public self-consciousness and social anxiety subscales correlated the most with dental anxiety. Furthermore, the data did not indicate a significant moderating relationship for gender between the two aforementioned variables. These results contribute to the establishment of personality characteristics as one of the dimensions determining dental anxiety.

2017-03-01

Fourteen dentists at different practices in the UK assessed the dental charts of 1128 patients who were new to the dentist but not new to the practice; 44% of the dental charts were found to be inaccurate. Inaccuracy of the individual practice-based charts ranged between 16% for the best performing practices to 83% for the worst: 5% of dental charts had too many teeth charted and 5% had too few teeth charted; 13% of charts had missed amalgam restorations and 18% had missed tooth-coloured restorations; 5% of charts had amalgam restorations recorded but with the surfaces incorrect (eg an MO restoration charted but a DO restoration actually present); 9% of charts had tooth-coloured restoration surfaces incorrectly recorded. For 7.5% of charts, amalgams were charted but not actually present. Other inaccuracies were also noted. The authors reinforce the requirements of the GDC, the advice of defence organizations, and the forensic importance of accurate dental charts. Clinical relevance: Dental charting forms part of the patient’s dental records, and the GDC requires dentists to maintain complete and accurate dental records.

Purpose: To establish a new method for dental imaging using magnetic resonance tomography named Dental-MRT and to demonstrate its usefulness in diagnosing dentogen pathologies of the mandible and maxilla. Methods: Seven healthy volunteers, three patients with pulpitis, two patients with dentigerous cysts, two patients after tooth transplantation, and three patients with atrophic mandibles have been evaluated. Optimized axial T{sub 1}- and T{sub 2}-weighted gradient echo and spin echo sequences in 2D and 3D technique have been established to perform studies of the jaws. The acquired images were reconstructed with a standard dental software package on a workstation as panorama and cross-sectional views of the mandible or maxilla. Results: The entire maxillo-mandibular bone, teeth, dental pulp, and the content of the mandibular canal were well depicted. Patients with pulpitis demonstrate bone marrow edema in the periapical region. Dentigerous cysts and their relation to the surrounding structures are clearly shown. After contrast media administration marked enhancement of the dental pulp can be demonstrated. Conclusion: Dental-MRT promises to provide a new tool for visualization and detection of dental diseases. (orig.)

What is dental ecology?

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.

Dental anxiety could impede dental treatment in children. Evidence shows that parents' fear of dentists contributes to children's anxiety towards dentists. The aim of the present study was to determine whether and to what extent: a) parents' anxiety and depression personality traits, b) parent's dental fear, and c) child personality traits can predict children's dental anxiety in an Italian population. One hundred and four children (5-14 years old) and one of their parents participated in the study. Well-known and validated questionnaires were administered to children (MCDASf, CFSS-DS, TAD) and parents (FDPQ, STAI Y1, Y2, and BDI-II). Dental anxiety is significantly associated with the anxiety personality trait and depression of the child and with parental fear of dental pain. A hierarchical regression analysis showed that, regardless of age and gender, the best predictor of child dental anxiety is parent's fear of dental pain, rather than relatively stable temperaments of the child. In line with the literature concerning adults, these findings highlight the children dental anxiety as a complex phenomena consisting of different components, including the child's personality traits (anxiety trait and depression) and parents' dental fear. Clinical implications of this evidence are discussed. © 2015 American Association of Public Health Dentistry.

2017-09-01

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.

Science.gov (United States)

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

Full Text Available Context: To investigate the antibiotic prescribing training received by dental students, clinical experience in treating child patients, awareness of antibiotic prescribing guidelines, preparedness in antibiotic prescribing, and compliance with antibiotic prescribing guidelines for the management of dental infections in children. Methods: This was a cross-sectional study involving final year dentals students from Malaysian and Asian dental schools. A self-administered questionnaire consisting of five clinical case scenarios was e-mailed to all final year students at selected dental schools. Students′ responses were compared for each clinical case scenario with the prescribing guidelines of the American Academy of Pediatric Dentistry and the American Dental Association. Compliance in each scenario was tested for association with their preparedness in antibiotic prescribing, previous training on antibiotic prescribing and awareness of antibiotic prescribing guidelines using Chi-square test. Data collected were analyzed using SPSS statistics version 20. Results: A total of 108 completed responses were received. About 74 (69% students were from Malaysian dental schools. The compliance rate with prescribing guidelines ranged from 15.7% to 43.5%. Those attending Malaysian dental schools (47.3% and those who had treated child patient more often (46.3% were more likely (P < 0.05 to be aware of the guidelines. Those who had received antibiotic prescribing training (21.3% were more likely to think they were well prepared in antibiotic prescribing (P < 0.05. Conclusions: Final year dental students had low awareness and compliance with antibiotic prescribing guidelines. Further research is needed to investigate how compliance with the guidelines may be enhanced.

Dental radiology is quickly becoming integral to the standard of care in veterinary dentistry. This is not only because it is critical for proper patient care, but also because client expectations have increased. Furthermore, providing dental radiographs as a routine service can create significant practice income. This article details numerous conditions that are indications for dental radiographs. As you will see, dental radiographs are often critical for proper diagnosis and treatment. These conditions should not be viewed as unusual; they are present within all of our practices. When you choose not to radiograph these teeth, you leave behind painful pathology. Utilizing the knowledge gained from dental radiographs will both improve patient care and increase acceptance of treatment recommendations. Consequently, this leads to increased numbers of dental procedures performed at your practice.

The purpose of this study was to analyze traumatic dental injuries in children visiting the dental hospital emergency department in Samsun of Turkey, in the period from 2007 to 2011. Data of age, gender, causes of dental trauma, injured teeth, type of dental injuries, the application period, the dental treatments, and traumatic dental injuries according to the seasons were obtained from the records at dental hospital. Of all 320 patients with traumatic dental injury, 205 were boys and 115 were girls with a boys/girls ratio 1.78:1. Traumatic dental injury was observed more frequently in the 7-12 age groups: 52.5% in girls and 67.8% in boys. Falls are the major cause of traumatic dental injury in the age group 6-12 (51.4%). Sport activities are a common cause of traumatic dental injury in the 7-12 age group (34.2%). Patients visited a dentist within approximately 2 h (57.1%). The upper anterior teeth were subjected to trauma more frequently than the lower anterior teeth. The maxillary central incisors were the most commonly affected teeth, and the mandibular canins were the least affected teeth. In primary teeth, avulsion was the most common type of dental injury (23%); on the other hand, enamel fractures were the most common type of dental injury (30.6%) observed in permanent teeth. In the primary dentition, the most commonly performed treatments were dental examination and prescribing (70%). The most common treatment choices in permanent teeth were restoration and dental examination (49.7 and 15.8%, respectively). The results of the study show that the emergency intervention to traumatized teeth is important for good prognosis of teeth and oral tissues. Therefore, the parents should be informed about dental trauma in schools, and dental hospital physicians should be subjected to postgraduate training.

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.

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.

The changing health care environment and societal imperatives indicate the need for transformative change within the dental hygiene profession to serve the emerging needs of the public. The American Dental Hygienists' Association is leading the way toward meaningful change. The American Dental Hygienists' Association (ADHA) has as its vision the integration of dental hygienists into the health care delivery system as essential primary care providers to expand access to oral health care. This article provides data on current dental hygiene education programs and those in development. Also included is a discussion regarding how the dental hygiene profession can better serve the health and wellness needs of society by transforming the way graduates are prepared for the future. ADHA's dental hygiene survey center data, policies and a futuristic analysis plus a review of the professional literature describe the current state of dental hygiene education and the profession. A discussion of societal, health care and educational trends that creates the imperative for transformation of the dental hygiene profession is provided. Ultimately, the purpose of advancing education in dental hygiene is to achieve better oral and overall health for more people. The profession's responsibility to the public includes evaluating its own ability to provide care and taking the steps necessary to ensure its maximum effectiveness. ADHA is leading this process for dental hygienists in diverse ways. It is imperative that the dental hygiene profession understands and embraces the changing health care environment. Through open dialog and the sharing of evidence the professional path will be determined along with forward movement for the benefit of society and the dental hygiene profession.

2013-01-01

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. 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. 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. 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.

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.

Crawford, W H

1986-05-01

Total expenditures and revenues of 58 US dental school were derived from reports of the ADA Division of Educational Measurements. These financial data were studied by type of dental school (public, state-related private, and private) and by expenditure/revenue categories. Dental schools showed little diversity in expenditures: most were directed toward instruction; few were directed toward research or continuing education. Several distinctive patterns among the three types of dental schools in revenues were observed. Two configurations emerged: public and state-related private dental schools receive more than 75% of their revenues from government and tuition, and private dental schools, more than 50%.

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

This study examines income inequalities in foregone dental care in 23 European countries during the years with global economic crisis. Associations between dental care coverage from public health budgets or social insurance, and income-related inequalities in perceived access to dental care, are analysed. Survey data 2008-2013 from 23 countries were combined with country data on macro-economic conditions and coverage for dental care. Foregone dental care was defined as self-reported abstentions from needed dental care because of costs or other crisis-related reasons. Age-standardized percentages reporting foregone dental care were estimated for respondents, age 20-74, in the lowest and highest income quartile. Associations between dental care coverage and income inequalities in foregone dental care, adjusted for macro-economic indicators, were examined by country-level regression models. In all 23 countries, respondents in the lowest income quartile reported significantly higher levels of foregone dental care than respondents in the highest quartile. During 2008-2013, income inequalities in foregone dental care widened significantly in 13 of 23 countries, but decreased in only three countries. Adjusted for countries' macro-economic situation and severity of the economic crisis, higher dental care coverage was significantly associated with smaller income inequalities in foregone dental care and less widening of these inequalities. Income-related inequalities in dental care have widened in Europe during the years with global economic crisis. Higher dental care coverage corresponded to less income-related inequalities in foregone dental care and less widening of these inequalities. © 2017 John Wiley & Sons A/S.

A trend towards increasingly new forms of dental practice has been observed in the FDI World Dental Federation. Elementary foundations such as the free dentist and therapy choice, and independent, free, self-responsible professional practice may be undermined. The current study is aimed at analyzing the general training framework, organization, and professional types of dental practice in the European Regional Organization (ERO) zone and at critically discussing selected aspects of changes in the dental profession. A questionnaire was developed by the ERO Working-Group "Liberal Dental Practice." Information about dental schools, professional organizations, dental practice regulations, and ambulatory healthcare centers was analyzed. Self-employed dental practice is the most common type of practice (51.7%). Dentists are allowed to work independently immediately after graduation (72.7%). Approximately one-third are organized as compulsory members in chambers/corporations. The density of dentists has a mean of 1,570 inhabitants per dentist. In most countries, there are no special rules for founding dental ambulatory healthcare centers. In a total of 353 universities of the ERO countries surveyed, 16,619 dentists per year were trained, with a trend toward a higher percentage of female students (63%). Despite modern forms of dental practice, the charter of the individual liberal dental profession (CED et al, 2013) should be respected and taken into account on the basis of ethical principles. The commercialization of the dental profession can be neutralized only by establishing and following well-defined ethical principles; oral healthcare quality can thus be ensured without the influence of third parties.

Dental OCT

Wilder-Smith, Petra; Otis, Linda; Zhang, Jun; Chen, Zhongping

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.

2014-10-01

To study if treatment under general anaesthesia (GA) is associated with dental neglect or dental disability. This was a retrospective study. Dental records of all children in the age 0-6 years who underwent GA at a specialist paediatric dentistry clinic during 2006-2011 were studied with regard to decayed-missed-filled teeth, traumatic injuries, emergency visits, behaviour management problems and the history of attendance. The final sample consisted of 134 children. Matched controls were selected among recall patients who had not received treatment under GA. Fishers exact test or Pearson Chi-square test analysed response distribution and comparisons between groups, and for multivariate analyses, logistic regression was used. The results show that children treated under GA had significantly higher caries prevalence, apical periodontitis and infections due to pulpal necrosis. Dental neglect as well as dental disability was significantly more prevalent in the GA group compared to the control group. In a multivariate analysis with dental neglect as independent factor, dental disability was the only significant factor (p = 0.006). Children treated under general anaesthesia were significantly more often diagnosed with both dental neglect and dental disability. Dental disability was the only factor significantly related to dental neglect. There is a need for improved documentation in the dental records to better identify dental neglect and dental disability, and also a continued training of dentists regarding child protection.

Exploring Current and Future Roles of Non-Dental Professionals: Implications for Dental Hygiene Education.

Science.gov (United States)

Maxey, Hannah L; Farrell, Christine; Gwozdek, Anne

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 21 st Century."

Occupational noise is unavoidably produced from dental equipment, building facilities, and human voices in the dental environment. The purpose of this study was to investigate the effect of occupational noise exposure on the dental professionals' health condition. The psychoacoustics approach noise exposure assessment followed by the health risk assessment was carried on at the paediatric dentistry clinic and the dental laboratory in the Prince Philip Dental Hospital of Hong Kong. The A-weighted equivalent sound level, total loudness, and sharpness values were statistically significantly higher for the noise at the laboratory than that at the clinic. The degree of perceived influences and sharpness of noise were found to have the impacts on the dental professionals' working performance and health. Moreover, the risk of having a bad hearing state would a have 26% and 31% higher chance for a unit increment of the short-term and long-term impact scores, respectively. The dental professionals with the service length more than 10 years and the daily working hours of more than eight showed the highest risk to their hearing state. The worse the hearing state was, the worse the health state was found for the dental professionals. Also, the risk of dissatisfaction would be increased by 4.41 and 1.22 times for those who worked at the laboratory and a unit increment of the long-term impact score. The constructed health risk mode with the scientific and statistical evidence is hence important for the future noise management of environmental improvement.

2014-01-01

Full Text Available Background: Dental waste can be hazardous to humans and the environment. Objective: To determine the current status of dental waste management in private and public dental clinics and private dental offices in Shiraz, southern Iran. Methods: This cross-sectional study was conducted at the Shiraz University of Medical Sciences from February through June 2013. A stratified random sampling method was used to study 86 private offices, 14 private clinics and 10 public clinics. Types of waste studied included mercury and amalgam, lead foil packets, sharps, infectious tissues and fluids, pharmaceuticals and domestic waste materials. Compliance with established standards by the monitored dental offices and clinics and public clinics were compared. Results: 89.1% of dental offices and clinics disposed their infectious waste with domestic waste. Only 60% of centers used standard method for sharps disposal. None of the dental centers disposed their pharmaceutical waste and x-ray fixer waste by standard methods. Less than 10% of centers recycled the amalgam and lead foil pockets waste to the manufacture. Conclusion: Government agencies should establish monitoring programs for all dental offices and clinics to identify noncompliant activity and enforce recommended regulations.

Full Text Available Se presenta claves taxonómicas basadas en características morfológicas dentarias externas e internas, que permiten el reconocimiento de cada orden, familia y género de los batoídeos conocidos en Chile. En algunos casos, como en las familias Rhinobatidae, Torpedinidae, Narcinidae, Myliobatidae, Mobulidae, Dasyatidae y Urotrygonidae, las claves permiten el reconocimiento específico pero, en otros casos, sólo se puede discriminar hasta género, dadas las limitaciones impuestas por los conocimientos existentes. Estas claves son una herramienta complementaria a la diagnosis de rayas y están orientadas al reconocimiento de fragmentos dentales, hallazgos paleontológicos de dientes así como para las piezas dentales asociadas con la mandíbula. De esta manera, se entrega un apoyo taxonómico nuevo con características dentales diferentes a las consideradas actualmente para este superorden.A series of keys with external and internal dental morphologic features for the identification of each order, family and genus of rays and skates of the batoids known in Chile, are presented. In the case of families Rhinobatidae, Torpedinidae, Narcinidae, Myliobatidae, Mobulidae, Dasyatidae and Urotrygonidae, an identification at the species level is possible. In other cases, due to limitations imposed by the existing knowledge, only discrimination up to genus is allowed. These keys are a complementary tool for the diagnosis of rays suitable for the identification of dental fragments, paleontological discoveries of teeth as well as for jaw teeth. This tool offers a novel taxonomic support, which includes dental features different from those considered nowadays for this superorder.

Access to dental care-parents' and caregivers' views on dental treatment services for people with disabilities.

LENUS (Irish Health Repository)

Prabhu, Neeta T

2010-03-01

The goal of this study was to elicit the views of patients or parents\\/caregivers of patients with disabilities regarding access to dental care. A questionnaire was generated both from interviews with patients\\/parents\\/caregivers already treated under sedation or general anesthesia as well as by use of the Delphi technique with other stakeholders. One hundred thirteen patients from across six community dental clinics and one dental hospital were included. Approximately, 38% of the subjects used a general dental practitioner and 35% used the community dental service for their dental care, with only 27% using the hospital dental services. Overall waiting time for an appointment at the secondary care setting was longer than for the primary care clinics. There was a high rate of parent\\/caregiver satisfaction with dental services and only five patients reported any difficulty with travel and access to clinics. This study highlights the need for a greater investment in education and training to improve skills in the primary dental care sector.

Dental PACS development in Korea

International Nuclear Information System (INIS)

Kim, Eun Kyung

2008-01-01

Picture archiving and communication system (PACS) is an image information technology system for the transmission and storage of medical images. In Korea the first full PACS was installed at Samsung Medical Center in 1994, but, the rate of distribution was very slow. The government's approval for the medical insurance reimbursement for full PACS examinations in November 1999 became the turning point. Thereafter the number of hospitals with full PACS has steeply increased. In September of this year, PACS was installed at 906 medical institutes, including most of university hospitals and general hospitals. The first full dental PACS was installed at Wonkwang University Dental Hospital in 2002. Now ten out of eleven university dental hospitals implemented full dental PACS. The current status and technological factors of dental PACS in Korean university dental hospitals and the future perspectives of dental PACS are described.

Manny, E.F.; Carlson, K.C.; McClean, P.M.; Rachlin, J.A.; Segal, P.

1980-01-01

To provide medical and scientific background on certain selected technologies generally considered to be of particular significance, the National Center for Health Care Technology (NCHCT) has commissioned a series of overview papers. This is one of several projects entered into jointly by the Bureau of Radiological Health (BRH) and NCHCT relating to the use of radiation for health care. Dental radiation protection has been a long-time interest of BRH. Both past and on-going efforts to minimize population radiation exposure from electronic products have included specific action programs directed at minimizing unnecessary radiation exposure to the population from dental radiology. Current efforts in quality assurance and referral criteria are two aspects of NCHCT's own assessment of this technology which are described within the larger picture presented in this overview. The issues considered in this document go beyond the radiation exposure aspects of dental x-ray procedures. To be responsive to the informational needs of NCHCT, the assessment includes various other factors that influence the practice of dental radiology. It is hoped this analysis will serve as the basis for planning and conducting future programs to improve the practice of dental radiology

This research presents the results of the microhardness of human dental enamel and of the following dental restorative materials: three dental porcelains - Ceramco II, Finesse and Noritake, and two resin restorative materials - Artglass and Targis, for materials submitted to different times of irradiation at the IEA-R1m nuclear reactor under a thermal neutron flux of 10 12 n cm -2 .s -1 . The results obtained indicated that there is a decrease of the surface microhardness when the enamel is irradiated for 1 h and when dental materials are irradiated for 3 h. However, enamels irradiated for 30 min. did not show significant change of their surface hardness. Therefore, the selection of irradiation time is an important factor to be considered when irradiated teeth or dental materials are used in the investigations of their properties. (author)

This cross-sectional study was to investigate correlations between molar incisor hypomineralisation (MIH), dental caries and child dental fear. The subjects in the study were representative samples of 8 and 14 year old children from three Greek cities (total N = 2335). Dental examinations were performed by one calibrated examiner in classrooms, after the children had brushed their teeth, using an intraoral mirror and artificial room light supplemented by a penlight. All the children completed the children's fear survey schedule-dental subscale (CFSS-DS) questionnaire. MIH scores were recorded using EAPD criteria and dental caries experience by DMFS/dmfs index. Data were analysed with the Chi-squared (χ (2)), Mann-Whitney and Spearman's rank correlation coefficient tests. The mean DMFS in children with MIH (8-year olds: 1.60 ± 2.01, 14-year olds: 4.60 ± 4.41) was statistically significantly higher than children without MIH (8-year olds: 1.01 ± 1.78, 14-year olds: 3.46 ± 4.28) (p MIH had statistically significantly higher mean DMFS scores than children with mild or no MIH (p MIH status (p = 0.332). Caries experience was associated with the MIH status of the first permanent molars in both age groups (p MIH (26.5 ± 9.6) (p = 0.339), regardless of MIH severity. A positive association between MIH and dental caries was confirmed and a lack of association found between MIH and dental fear in Greek children.

A humanistic environment for dental schools: what are dental students experiencing?

Science.gov (United States)

Quick, Karin K

2014-12-01

A Commission on Dental Accreditation (CODA) standard now requires that dental schools commit to establishing a "humanistic culture and learning environment" for all members of the academic environment. The aim of this study was to identify students' perceptions of factors that affect the dental school environment and to test differences in their experiences in terms of gender and year. This picture of the existing environment was meant to serve as a first step toward creating and supporting a more humanistic academic environment. A mixed-methods approach was used for data collection during the 2009-10 and 2010-11 academic years at one U.S. dental school. Four focus groups were first conducted to explore challenges and conflicts faced by students during their dental education. A written survey informed by the focus group results was then used to obtain quantitative data. The survey response rate was 47 percent (N=188). Faculty inconsistency, cheating, and belittlement/disrespect were experienced by many of the responding dental students during their education, similar to what has been documented in medicine. These students also reported experiencing both constructive communication (90 percent) and destructive communication (up to 32 percent). The female students reported more gender discrimination and sexual harassment than their male peers, and the clinical students reported more experience with belittlement and destructive communication than the preclinical students. The results suggest that greater effort should be directed toward creating a more humanistic environment in dental schools. Based on the issues identified, steps academic institutions can take to improve these environments and student skills are outlined.

Full Text Available En España la leishmaniasis es una zoonosis endémica presente en la mayor parte del territorio peninsular e Islas Baleares. El parásito que se detecta es la Leishmania infantum y el principal reservorio es el perro. Los vectores competentes para transmitir el parásito son los flebotomos, de los que existen dos especies distribuidas por todo el territorio peninsular e Islas Baleares. En este artículo se revisa la situación actual y el comportamiento de la leishmaniasis en España. Se analiza y compara la información sobre la enfermedad procedente de las altas hospitalarias y de la Red Nacional de Vigilancia Epidemiológica así como los factores de riesgo identificados en estudios anteriores que facilitan la transmisión. Desde 2009 está teniendo lugar un brote en el suroeste de la Comunidad de Madrid, destacando el elevado número de casos, cerca de 400 y la detección de un nuevo reservorio, la liebre. Las condiciones que pueden incrementar la incidencia de la leishmaniasis están asociadas al aumento del número de vectores infectados, al de la densidad del flebotomo, al de hospedadores o la aparición de nuevos reservorios en un área geográfica. Esta infección tiene una dinámica de transmisión compleja y para responder oportunamente a los brotes debe estar previamente desarrollado un plan de acción integral y multisectorial en el que participen todas las instituciones involucradas. Ante un brote, es importante estudiar los factores que condicionan la transmisión del lugar y adaptar el plan de acción a sus características específicas.

To determine first-year dental students' current motivation and attitudes for choosing the dental profession at the Faculty of Dental Medicine, Medical University - Sofia, Bulgaria. An anonymous questionnaire, consisting of 12 questions about students' socio-demographic profile and their motivation for choosing dentistry, was administered to 119 first-year dental students at the Faculty of Dental Medicine of the Medical University of Sofia. The study was conducted at the beginning of the 2012-2013 academic year. The data was processed and analyzed with the following software: Microsoft Windows Server 2008 R2; Microsoft SQL Server 2008; Internet Information Server 7.5.; Microsoft SharePoint Server 2010. The majority of the students (73%) were self-motivated for choosing dentistry as a career; 61% of them did not have relatives in the medical profession; 43% chose dental medicine because it is a prestigious, humane and noble profession; 50% - for financial security; 59% - because of the independence that it provides. There were no significant differences in the motivation between males and females. Independence, financial security and 'prestige' were the predominant motivating factors in this group of first-year dental students. Determining the reasons for choosing dentistry has important implications for the selection and training of students as well as for their future job satisfaction.

The virtual dental home: a critique.

Science.gov (United States)

Friedman, Jay W; Nash, David A; Mathu-Muju, Kavita R

2017-09-01

The Virtual Dental Home is a concept of the Pacific Center for Special Care of the Arthur A. Dugoni School of Dentistry in San Francisco. It is designed to improve access to dental care for underserved populations, specifically children and institutionalized adults. This article describes the development and implementation of the Virtual Dental Home, subsequently critiquing the concept. The criteria for a dental home are not met by the program. It is the equivalent of a traditional public oral health prevention and screening program, with the additional dimension of allowing dental hygienists and assistants to place interim glass ionomer restorations in dental cavities. The critique questions the need to insert a "cloud" dentist into the process. The routine utilization of radiographs is also challenged. The VDH not only lacks the attributes of a dental home, it has not been shown to be as efficient and effective as traditional programs staffed by dental hygienists and dental therapists. The article concludes by describing how programs utilizing dental therapists could address the deficiencies of the Virtual Dental Home, effectively improving access to oral health care for underserved populations. © 2017 American Association of Public Health Dentistry.

2016-01-01

Growing distribution and utilization of digital volume tomography (DVT) extend the spectrum of clinical dental imaging. Additional diagnostic value, however, comes along with an increasing amount of radiation. In contrast, magnetic resonance imaging is a radiation free imaging technique. Furthermore, it offers a high soft tissue contrast. Morphological and numerical dental anomalies, differentiation of periapical lesions and exclusion of complications of dental diseases are field of applications for dental MRI. In addition, detection of caries and periodontal lesions and injury of inferior alveolar nerve are promising application areas in the future.

The vicious cycle of dental fear: exploring the interplay between oral health, service utilization and dental fear

Directory of Open Access Journals (Sweden)

Spencer A John

2007-01-01

Full Text Available Abstract Background Based on the hypothesis that a vicious cycle of dental fear exists, whereby the consequences of fear tend to maintain that fear, the relationship between dental fear, self-reported oral health status and the use of dental services was explored. Methods The study used a telephone interview survey with interviews predominantly conducted in 2002. A random sample of 6,112 Australian residents aged 16 years and over was selected from 13 strata across all States and Territories. Data were weighted across strata and by age and sex to obtain unbiased population estimates. Results People with higher dental fear visited the dentist less often and indicated a longer expected time before visiting a dentist in the future. Higher dental fear was associated with greater perceived need for dental treatment, increased social impact of oral ill-health and worse self-rated oral health. Visiting patterns associated with higher dental fear were more likely to be symptom driven with dental visits more likely to be for a problem or for the relief of pain. All the relationships assumed by a vicious cycle of dental fear were significant. In all, 29.2% of people who were very afraid of going to the dentist had delayed dental visiting, poor oral health and symptom-driven treatment seeking compared to 11.6% of people with no dental fear. Conclusion Results are consistent with a hypothesised vicious cycle of dental fear whereby people with high dental fear are more likely to delay treatment, leading to more extensive dental problems and symptomatic visiting patterns which feed back into the maintenance or exacerbation of existing dental fear.

2015-01-01

Background: 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. Method: 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. Results: 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 percentage) males and 129 (51.2 percentage) females. Out of these children 150 (59.5 percentage) had previously visited a dentist and 102 (40.5 percentage) had no experience with a dentist before; 38 percentage (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. Conclusion: 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. (author)

Changes in sick leave among Swedish dental patients after treatment for dental fear.

Science.gov (United States)

Hakeberg, M; Berggren, U

1993-03-01

The most obvious consequence of a genuine dental phobic reaction is the avoidance of necessary dental care. Previous research has indicated that such avoidance results in deterioration of the oral status, which subsequently worsens patients' well-being and quality of life. The authors' previous investigations have shown overt behavioural and social effects by an increased time spent on sick leave compared with the public experience. Self-reports by patients also indicated that the time spent on sick leave was reduced after successful treatment for dental fear. The present investigation assessed the frequency of sick leave days among patients with dental fear and avoidance with regard to successful or unsuccessful treatment for dental fear (subsequent regular dental visit habits). A sub-sample of the fear group was compared with a group of matched controls. Data were collected from the official register of the National Health Insurance Board. It was revealed that the number of sick leave days was significantly reduced after treatment for dental fear among treated patients. This effect was also confirmed by a significant post-treatment difference between treated patients and those who discontinued or never started treatment. When compared with a matched control group, the positive change was further supported by a significant pre-treatment difference and a non-significant post-treatment difference.

2012-05-01

The goals of this study were to 1) evaluate dental students' perceptions of dental specialties, 2) identify factors that play an important role in students' decision to pursue specialty training or career choices, and 3) establish a baseline of students' perceptions of the dental fields with the best future in terms of salary, personal and patient quality of life, and overall impact on the dental profession. Surveys were distributed to 494 students at the University of Pennsylvania School of Dental Medicine. Data were collected from 380 traditional four-year students and thirty advanced standing students. Chi-square tests, multivariate analysis, and logistic regressions were used to determine associations and independent contributions of student demographics to their perceptions of dental specialties and factors influencing specialty training or career choices. Debt was a statistically significant factor (p<0.001) in choosing specialty training or career independent of gender, age, or class year. Enjoyment of providing care in a specialty or field was identified as the single most important factor in choosing a specialty career. Half of the respondents had decided not to specialize. Pursuing postdoctoral general dentistry training and private practice in general dentistry were the most commonly reported plans after completion of dental school. Suggestions are made for ways to inform students about specialty training.

1998-01-01

The purpose of this study was to assess the representation of academically based diplomates of the American Board of Dental Public Health (ABDPH) and to identify their perceptions on the training of dental public health predoctoral faculty. Data were collected by a mailed, self-administered, 13-item questionnaire. The population was the 48 diplomates of the ABDPH as of March 1997 associated with academic institutions. Twenty of the 55 US dental schools had a diplomate of the ABDPH with a mean of 1.8 diplomates per school with a diplomate. An average of 4.5 full-time faculty members per school were associated with teaching dental public health. A master's degree in public health (MPH) was the most frequently suggested educational requirement for dental public health faculty. Continuing education courses were training needs perceived for dental public health faculty. The lack of time, money, and incentives, along with perceived rigidity of requirements for board certification, were reported as major barriers for faculty becoming dental public health board certified. Numerous challenges confront the development of a strong dental public health presence in US dental schools. These challenges include, among others, insufficient numbers of academic dental public health specialists and insufficient motivations to encourage promising candidates to pursue specialty status.

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.

Full Text Available O objetivo deste trabalho foi estudar a importância do pH da dieta líquida na etiologia e prevenção das lesões de erosão dental, bem como conhecer o pH de algumas bebidas e sucos, supostamente ácidos, mais consumidos em nosso meio, para que fosse possível estabelecer uma comparação destes valores a fim de controlar a dieta dos pacientes portadores de lesões de erosão dental. Um único exemplar de cada fruta madura foi processado puro de modo a ser liquefeito e o pH foi medido utilizando-se um pH-metro, imediatamente e depois de 30 minutos. Posteriormente, a amostra de suco foi diluída em água na proporção de 1:2 e novas medidas foram tomadas. Para as bebidas industrializadas, as medidas de pH foram realizadas imediatamente após a abertura do frasco e depois de 30 minutos. As bebidas e sucos analisados mostraram valores abaixo do pH crítico de dissolução da estrutura dental, sugerindo a possibilidade de favorecerem a desmineralização. A orientação quanto à dieta ácida parece ser um fator importante no tratamento e prevenção das lesões de erosão dental.The aim of this paper was to evaluate the importance of the liquid diet pH in the etiology and prevention of dental erosion, so as to give dietary orientation to patients who present with these lesions, as well as to know the pH of the most consumed Brazilian fruit juices and industrialized beverages, which are supposably acid. A sample of each mature fruit was processed to be liquefied, and the pH was obtained through a pHmeter appliance, immediately after the juices were obtained and 30 minutes later. Afterward the juices were diluted in potable water in a 1:2 proportion and new pH values were obtained. For the industrialized beverages, pH measurements were carried out immediately after opening the bottles and 30 minutes later. The beverages and juices analyzed showed pH values below the critical pH for dental tissue dissolution (5.5. Therefore, they are expected to

Objective: To evaluate the dental anxiety levels and to assess its correlation with self-assessed dental status and treatment needs of patients. Methods: The study was conducted at the Out Patient Department of Dr. Ishrat-ul-Ebad Khan Institute of Oral Health Sciences, Karachi. Using non-probability quota sampling, the study included the first 32 patients between 18 and 35 years of age, visiting the facility. Over a period of one month (22 working days) 704 patients comprised the study population. They were interviewed using a structured questionnaire to self-assess their dental anxiety levels, oral health status and treatment needs. The data was analysed using SPSS 17.0 with descriptive frequencies and chi-square test. Results: Of the total participants, 650 (92.32%) patients provided consent. Average dental anxiety scale score was 12.46, representing high anxiety score. There were 174 (26.8%) smokers; only 234 (36%) had visited a dentist less than a year ago; 385 (59.2%) considered their dental health to be satisfactory; 306 (47.1%) thought of their treatment needs to be little'; 222 (34.2%) brushed their teeth twice daily. Dental anxiety was statistically significant with treatment needs and dental status. Relation of tooth-brushing with last dental visit and treatment needs was also found to be significant. Conclusion: A high level of dental anxiety was observed among the study population. The dental professionals should seek ways to help dentally anxious individuals. (author)

Little is known about dental case managers as few programs have been scientifically evaluated. The goal of this study was to explore the impact of dental case manager on retention in dental care and completion of treatment plans, while specifically exploring the number of dental case manager encounters. Fourteen programs enrolled people with HIV/AIDS (PLWHA) in dental care and a longitudinal study between 2007 and 2009. The 758 participants had a total of 2715 encounters with a dental case manager over twelve months: 29% had a single encounter; 21% had two; 27% had 3-4 and; 23% had 5-29 encounters. Adjusting for baseline characteristics, participants receiving more encounters were significantly more likely to complete their Phase 1 treatment plan, be retained in dental care, and experience improvements in overall oral health status. Organizations considering efforts to improve the oral health of vulnerable, hard-to-engage populations should consider these findings when planning interventions. ©2012 Special Care Dentistry Association and Wiley Periodicals, Inc.

The aim of this study was to examine the clinical characteristics of dental emergency patients who visited a university hospital emergency center and to evaluate the incidence of dental trauma. A retrospective chart review of patients with dental complaints and who visited the Seoul National University Bundang Hospital (SNUBH) emergency center in Gyeonggi-do, Korea, from January 2009 to December 2009 was conducted. Information regarding age, gender, the time, day, and month of presentation, diagnosis, treatment, and follow up was collected and analyzed. One thousand four hundred twenty-five patients with dental problems visited the SNUBH emergency center. Dental patients accounted for 1.47% of the total 96,708 patients at the emergency center. The male-to-female ratio was 1.68:1, with a considerably larger number of male patients (62.7%). The age distribution peak was at 0-9 years (27.5%), followed by patients in their forties (14.1%). The number of patients visiting the dental emergency center peaked in May (14.2%), on Sundays (22.4%), and between 2100 and 2400 h (20.8%). The patients' chief complaints were as follows: dental trauma, dental infection, oral bleeding, and temporomandibular joint disorder (TMD). The prevalence of dental trauma was 66%. The reasons for dental emergency visits included the following: dental trauma, dental infection, oral bleeding, and TMD, with 66% of the patients requiring management of dental trauma. It is important that dentists make a prompt, accurate diagnosis and initiate effective treatment in case of dental emergencies, especially dental trauma. © 2011 John Wiley & Sons A/S.

The Ukrainian Dental Market: Characteristics of Demand for Services in the Segment of Dental Implantation

Directory of Open Access Journals (Sweden)

Slipchenko Tetiana O.

2017-05-01

Full Text Available The article is aimed at analyzing the market for dental services in Ukraine in the implantology segment, studying the demand factors for these services and developing a system of measures to manage the demand for dental implantation services. It has been proven that the market for dental services according to a complex of its attributes is more in line with the type of market of monopolistic competition. One of the promising ways of developing the dental market is to transform producers of dental services into the vertically integrated holdings. As one of the specific features of the dental services market is allocated the asymmetry of information, which leads to a conflict between the medical and economic interests of dentists. The price and non-price factors of demand for dental implantation services were determined, the prime cost structure of a dental service was analyzed. The characteristic attributes of a medical service have been defined as consistently defined actions or a complex of actions by medical personnel aimed at prevention, diagnosis, treatment, and rehabilitation, which have a self-contained complete meaning and a certain price.

2013-12-01

The study aimed to assess the awareness of the Consumer Protection Act among dental health professionals in dental schools of Ghaziabad, India. A cross-sectional questionnaire survey was carried out on dental health professionals in dental schools of Ghaziabad, India. A total of 348 dental health professionals (170 males and 178 females) were surveyed, out of which 116 were MDS faculty, 45 were BDS faculty and 187 were pursuing post graduation. The questionnaire comprised of 24 questions about the awareness of consumer protection act. Statistical analysis was done using Chi-square test, student's t test and ANOVA. A total of 84.8% (n=295) reported to be aware of consumer protection act. Amongst them, MDS faculty showed more awareness as compared to BDS faculty and those pursuing post-graduation. Considering the present scenario, MDS faculty dental professionals have more awareness of consumer protection act compared to other dental professionals. So, we must upgrade our knowledge on consumer protection act at all levels of our profession and change our attitude by inculcating a practice to spread the message of consumer protection act for delivering quality dental care.

The aims of this study were to assess curricular coverage of lesbian, gay, bisexual, and transgender (LGBT) content in U.S. and Canadian dental schools and U.S. dental hygiene programs, including hours of LGBT content, pedagogy used, and assessment methods, and to determine whether respondents perceived their institution's coverage as adequate. Data were collected from academic deans at 32 U.S. and two Canadian dental schools and from program directors at 71 U.S. dental hygiene programs (response rates 49%, 20%, 23%, respectively). The results showed that 29% of responding dental schools and 48% of responding dental hygiene programs did not cover LGBT content. Among the respondents, dental schools dedicated on average 3.68 hours and dental hygiene programs 1.25 hours in required settings to LGBT content. Lectures (dental schools 68%, dental hygiene programs 45%) and small group instruction (43%, 25%) were reported as the most common methodology used in teaching this content. Most of the responding dental schools and dental hygiene programs covered HIV (85%, 53%), oral disease risk (63%, 54%), and barriers to accessing health care for LGBT people (58%, 38%). Up to a third reported no need for coverage of topics such as sexual orientation (21%, 32%), coming out (29%, 37%), transitioning (29%, 38%), and sex reassignment surgery (32%, 35%). Assessment was through written examinations (41%, 30%) and faculty-observed patient interactions (21%, 23%); some respondents (20%, 33%) reported no assessment of learning outcomes. The most frequently endorsed strategies for increasing LGBT content were receiving curricular material focusing on LGBT-related health issues and health disparities and having trained faculty to teach LGBT content.

Taichman, Russell S.; Parkinson, Joseph W.; Nelson, Bonnie A.; Nordquist, Barbara; Ferguson-Young, Daphne C.; Thompson, Joseph F.

2012-01-01

Since leadership is an essential part of the oral health professions, oral health educators can play an essential role in establishing a culture of leadership and in mentoring students to prepare them for future leadership roles within the profession. However, leadership training for oral health professionals is a relatively new concept and is frequently not found within dental and dental hygiene curricula. The purpose of this article is to propose several models for leadership training that are specific to the oral health professions. The authors hope that providing an overview of leadership programs in academic dental institutions will encourage all U.S. and Canadian dental schools to begin developing a culture that promotes leadership development.

BACKGROUND. The change towards a more Westernised diet in Libya may increase the risk of caries and erosion in children. AIMS. To investigate any association between dental caries, dental erosion, and potential dietary risk factors in Libyan schoolchildren. METHODS. A random sample of 791 schoolchildren aged 12 years underwent dental examination for caries and erosion and completed a questionnaire to provide dietary data. Dental caries was assessed using the WHO (Oral Health Surveys: Basic Methods, 1997) criteria. Erosion was assessed using UK National Diet and Nutrition Survey (NDNS, Young People Aged 4-18 years. Volume 2: Report of the Oral Health Survey, 2000) criteria. Associations between caries and dietary variables were investigated through bivariate and multivariate analyses. RESULTS. Of the 791 12-year olds, 57.8% (457) had caries experience and 40.8% (323) had experience of erosion. One hundred and ninety-two subjects (42%) of the subjects with caries experience also had erosion, whilst 131 subjects (39.2%) of the 334 without caries had clinical signs of erosion (P = 0.464; OR, 1.123; 95% CI, 0.842, 1.497). There was no statistically significantly relationship between dental caries and dental erosion. Frequency of consumption of fruit-based sugared drinks was statistically significantly positively associated with experience of caries (P = 0.002). CONCLUSIONS. Dental caries experience was associated with frequency of consumption of sugared dietary items but not with dental erosion. © 2011 The Authors.

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

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.

Effects of a proposed rural dental school on regional dental workforce and access to care.

Science.gov (United States)

Wanchek, Tanya N; Rephann, Terance J

2013-01-01

Southwest Virginia is a rural, low-income region with a relatively small dentist workforce and poor oral health outcomes. The opening of a dental school in the region has been proposed by policy-makers as one approach to improving the size of the dentist workforce and oral health outcomes. A policy simulation was conducted to assess how a hypothetical dental school in rural Southwest Virginia would affect the availability of dentists and utilization levels of dental services. The simulation focuses on two channels through which the dental school would most likely affect the region. First, the number of graduates who are expected to remain in the region was varied, based on the extensiveness of the education pipeline used to attract local students. Second, the number of patients treated in the dental school clinic under different dental school clinical models, including the traditional model, a patient-centered clinic model and a community-based clinic model, was varied in the simulation to obtain a range of additional dentists and utilization rates under differing dental school models. Under a set of plausible assumptions, the low yield scenario (ie private school with a traditional clinic) would result in three additional dentists residing in the region and a total of 8090 additional underserved patients receiving care. Under the high yield scenario (ie dental pipeline program with community based clinics) nine new dentists would reside in the region and as many as 18 054 underserved patients would receive care. Even with the high yield scenario and the strong assumption that these patients would not otherwise access care, the utilization rate increases to 68.9% from its current 60.1%. While the new dental school in Southwest Virginia would increase the dentist workforce and utilization rates, the high cost combined with the continued low rate of dental utilization suggests that there may be more effective alternatives to improving oral health in rural areas

A systematic review was conducted to analyze Brazilian scientific and technological production related to the dental materials field over the past 50 years. This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (Prisma) statement. Searches were performed until December 2014 in six databases: MedLine (PubMed), Scopus, LILACS, IBECS, BBO, and the Cochrane Library. Additionally, the Brazilian patent database (INPI - Instituto Nacional de Propriedade Industrial) was screened in order to get an overview of Brazilian technological development in the dental materials field. Two reviewers independently analyzed the documents. Only studies and patents related to dental materials were included in this review. Data regarding the material category, dental specialty, number of documents and patents, filiation countries, and the number of citations were tabulated and analyzed in Microsoft Office Excel (Microsoft Corporation, Redmond, Washington, United States). A total of 115,806 studies and 53 patents were related to dental materials and were included in this review. Brazil had 8% affiliation in studies related to dental materials, and the majority of the papers published were related to dental implants (1,137 papers), synthetic resins (681 papers), dental cements (440 papers), dental alloys (392 papers) and dental adhesives (361 papers). The Brazilian technological development with patented dental materials was smaller than the scientific production. The most patented type of material was dental alloys (11 patents), followed by dental implants (8 patents) and composite resins (7 patents). Dental materials science has had a substantial number of records, demonstrating an important presence in scientific and technological development of dentistry. In addition, it is important to approximate the relationship between academia and industry to expand the technological development in countries such as Brazil.

Bensch, Brittany

2010-01-01

Student advocacy and involvement in the political process is built into the structure of the American Student Dental Association (ASDA), especially in its Legislative Grassroots Network and an internal communication network among students to ensure political awareness. Students are concerned with such issues as a universally accepted, non-patient-based licensure process, mid-level providers, loan availability and tax deductibility, financial support for schools, and service early in one's professional career (giving forward rather than giving back). Through collaboration with the American Dental Education Association and with many state associations, students participate in lobbying, awareness campaigns, and behind the scenes as legislative aids. Although students share the same love for the profession that animates established practitioners, they are perceived by legislators as being different. Students are involved in the legislative process because it represents their future.

The current political environment in the nation's capital threatens federal support for programs vital to the academic dental community. To develop a strong cadre of advocates who can deliver an effective and unified message to members of Congress on behalf of dental education and dental research, the American Dental Education Association (ADEA) and the American Association for Dental Research (AADR) created a new organizational structure: the National Oral Health Advocacy Committee (NOHAC) and the National Advocacy Network (NAN). The basic skills and knowledge required to function as an effective advocate include an understanding of the political environment, a working knowledge of the legislative processes and the political players, and the ability to build and work with grassroots networks and coalitions. NOHAC and NAN are designed to provide leadership in these areas to support effective advocacy for dental education and dental research.

Australia is one of the least densely populated countries in the world, with a population concentrated on or around coastal areas. Up to 33% of the Australian population are likely to have untreated dental decay, while people with inadequate dentition (fewer than 21 teeth) account for up to 34% of Australian adults. Historically, inadequate access to public dental care has resulted in long waiting lists, received much media coverage and been the subject of a new federal and state initiative. The objective of this research was to gauge the potential for reducing the national dental waiting list through geographical advantage, which could arise from subcontracting the delivery of subsidised dental care to the existing network of private dental clinics across Australia. Eligible population data were collected from the Australian Bureau of Statistics website. Waiting list data from across Australia were collected from publicly available sources and confirmed through direct communication with each individual state or territory dental health body. Quantum geographic information system software was used to map distribution of the eligible population across Australia by statistical area, and to plot locations of government and private dental clinics. Catchment areas of 5 km for metropolitan clinics and 5 km and 50 km for rural clinics were defined. The number of people on the waiting list and those eligible for subsidised dental care covered by each of the catchment areas was calculated. Percentage of the eligible population and those on the waiting list that could benefit from the potential improvement in geographic access was ascertained for metropolitan and rural residents. Fifty three percent of people on the waiting list resided within metropolitan areas. Rural and remote residents made up 47% of the population waiting to receive care.

The benefit for the child from the judicious use of diagnostic dental radiography is improved dental health. The risk to the child from dental diagnostic radiation exposure appears to be extremely low. Despite the low risk, the dentist must minimize the child's exposure to ionizing radiation by using sound clinical judgment to determine what radiographs are necessary and to provide children with optimal protection from ionizing radiation

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

Science.gov (United States)

Carson, P; Freeman, R

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

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.

2016-01-01

Full Text Available Dental anomalies are usual congenital malformation that can happen either as isolated findings or as a part of a syndrome. Developmental anomalies influencing the morphology exists in both deciduous and permanent dentition and shows different forms such as gemination, fusion, concrescence, dilaceration, dens evaginatus (DE, enamel pearls, taurodontism or peg-shaped laterals. All These anomalies have clinical significance concerning aesthetics, malocclusion and more necessary preparing of the development of dental decays and oral diseases. Through a search in PubMed, Google, Scopus and Medline, a total of eighty original research papers during 1928-2016 were found with the keywords such as dental anomaly, syndrome, tooth and hypodontia. One hundred review titles were identified, eighty reviews were retrieved that were finally included as being relevant and of sufficient quality. In this review, dental anomalies including gemination, fusion, concrescence, dilaceration, dens invaginatus, DE, taurodontism, enamel pearls, fluorosis, peg-shaped laterals, dentinal dysplasia, regional odontodysplasia and hypodontia are discussed. Diagnosing dental abnormality needs a thorough evaluation of the patient, involving a medical, dental, familial and clinical history. Clinical examination and radiographic evaluation and in some of the cases, specific laboratory tests are also needed. Developmental dental anomalies require careful examination and treatment planning. Where one anomaly is present, clinicians should suspect that other anomalies may also be present. Moreover, careful clinical and radiographical examination is required. Furthermore, more complex cases need multidisciplinary planning and treatment.

Hence, has contributed to the suitable replacement of missing teeth and the realization of an optimal facial appearance. This paper describes the benefits, applications, contraindications, and complications of dental implants in contemporary dental practice. Materials and Methods: An electronic search was undertaken in PUBMED without time restriction for appropriate English papers on dental implants based on a series of keywords in different combinations. Results: Fifty-eight acceptable, relevant articles were selected for review. The review identified the various components of dental implants, classification, and brands. It also looked at osseointegration and factors promoting and inimical to it. It also explored primary and secondary stability; and patients' selection for a dental implant. Complications of dental implants were also highlighted. Conclusion: With over 95% success rate, dental implants remain the gold standard for achieving aesthetic and functional oral rehabilitation.

Managing dental erosion.

Science.gov (United States)

Curtis, Donald A; Jayanetti, Jay; Chu, Raymond; Staninec, Michal

2012-01-01

The clinical signs of dental erosion are initially subtle, yet often progress because the patient remains asymptomatic, unaware and uninformed. Erosion typically works synergistically with abrasion and attrition to cause loss of tooth structure, making diagnosis and management complex. The purpose of this article is to outline clinical examples of patients with dental erosion that highlight the strategy of early identification, patient education and conservative restorative management. Dental erosion is defined as the pathologic chronic loss of dental hard tissues as a result of the chemical influence of exogenous or endogenous acids without bacterial involvement. Like caries or periodontal disease, erosion has a multifactorial etiology and requires a thorough history and examination for diagnosis. It also requires patient understanding and compliance for improved outcomes. Erosion can affect the loss of tooth structure in isolation of other cofactors, but most often works in synergy with abrasion and attrition in the loss of tooth structure (Table 1). Although erosion is thought to be an underlying etiology of dentin sensitivity, erosion and loss of tooth structure often occurs with few symptoms. The purpose of this article is threefold: first, to outline existing barriers that may limit early management of dental erosion. Second, to review the clinical assessment required to establish a diagnosis of erosion. And third, to outline clinical examples that review options to restore lost tooth structure. The authors have included illustrations they hope will be used to improve patient understanding and motivation in the early management of dental erosion.

The aim of this study was to evaluate whether there is an association between risk behavior for eating disorders (EDs) and dental erosion and caries. A controlled cross-sectional study was conducted in Brazil, involving 850 randomly selected female adolescents. After evaluating risk behavior for eating disorders through the Bulimic Investigatory Test of Edinburgh, 12 adolescents were identified with severe risk behavior for EDs and matched to 48 adolescents without such risk. Dental examinations, anthropometric measurements, and eating habits and oral hygiene were performed. Adolescents with high severity eating disorder condition were not more likely to show dental caries ( p = 0.329; OR = 2.2, 95% CI: 0.35-13.72) or dental erosion ( p = 0.590; OR = 2.33; 95% CI: 0.56-9.70). Adolescents with high body mass index (BMI) were five times more likely to have high severity eating disorder condition ( p = 0.031; OR = 5.1; 95% CI: 1.61-23.07). Therefore, high severity risk behavior for EDs was not significantly associated with dental caries and dental erosion. However, high BMI was a risk factor for developing eating disorders and should be an alert for individuals with this condition.

What Will Dental Practice Be Like In 2025? Will You Help Dental Hypotheses Find Answers

2011-02-01

Full Text Available As a result of the rapid acceptance of digital dental equipment, the dental office of 2011 looks very different from that of 1900. Despite these changes, the general dentist of 2011 performs almost the same functions as in 1900 namely the restoration of decayed teeth and the replacement of those lost due to disease. In addition to changes in technology, the last few decades of the 20th century ushered in a revolution in biology leading to the development of a genomic basis of dental disease and the development of bio-based diagnostics and therapeutics. In 2011 few if any of these bio-discoveries have changed dental practice but by 2025 we expect they will. In this editorial, Dental Hypotheses asks readers to “hypothesize” on what dental practice will be like in 2025.

Identifying barriers to receiving preventive dental services: expanding access to preventive dental hygiene services through affiliated practice.

Gross-Panico, Michelle L; Freeman, Wilbur K

2012-01-01

Minority children and children from lower income families are more likely to experience the burden of oral disease. Since oral disease reduces quality of life, it is a priority to utilize preventive dental services. The research questions ask if affiliated practice increases utilization of preventive dental services by underserved children from birth to 18 years of age, and what the barriers to receiving preventive dental services are and their level of importance. A survey was administered to parents/guardians of patients from birth to 18 years of age who received preventive dental services from Catholic Healthcare West East Valley Children's Dental Clinic, an affiliated practice dental clinic in Chandler, Arizona. Thirty-four surveys were completed: 21 completed in English and 13 completed in Spanish. The data was analyzed to provide descriptive statistics and non-parametrically analyzed using the Friedman's, Kendall's W and Wilcoxon Signed Ranks Tests. The cost of preventive dental services is more important to this population than both convenience of appointment time and distance traveled. As the cost increases for preventive dental services, this population will utilize preventive dental services less frequently. The study indicated that the increase of self-reported utilization of preventive dental services by underserved children, ranging in age from birth to 18 years old, in Arizona affiliated practice dental clinics, was primarily impacted by perceived reduced costs of receiving care. Funding efforts, reimbursement mechanisms and legislative policies should support this dental care delivery model to provide care to underserved children, adults and seniors throughout the U.S.

People with disabilities experience barriers to dental care, which may vary depending on type of disability and disability complexity (e.g., impact on activities of daily living). The purpose of this study was to examine differences in dental insurance, receipt of dental checkups, and delayed and unmet needs for dental care by type and complexity of disability. We conducted cross-sectional analysis of 2002-2011 data from the Medical Expenditure Panel Survey. Multivariable logistic regression analyses compared adults ages 18-64 in five disability type groups (physical, cognitive, vision, hearing, or multiple disabilities) to those with no disabilities, and compared people with complex activity limitations to those without complex limitations. All disability types except hearing had significantly higher adjusted odds of being without dental insurance, as did people with complex activity limitations. All disability groups except those with cognitive disabilities had increased odds of receiving dental checkups less than once a year. Similarly, all disability groups were at increased risk of both delayed and unmet needs for dental care. Odds ratios were generally highest for people with multiple types of disabilities. There are significant disparities in having dental insurance and receiving dental care for adults with disabilities, especially those with multiple types of disabilities, after controlling for socioeconomic and demographic differences. Further, disparities in care were apparent even when controlling for presence of dental insurance. © 2016 American Association of Public Health Dentistry.

The histomorphometric test is the gold standard for dental implant stability quantification; however, it is invasive, and therefore, it is inapplicable to clinical patients. Consequently, accurate and objective alternative methods are required. Resonance frequency analysis (RFA) and digital radiographic analysis are noninvasive methods with excellent objectivity and reproducibility. To analyze the correlation between the radiographic analysis of alveolar bone density around a dental implant and the resonance frequency of the dental implant. Digital radiographic images for 35 samples were obtained, and the resonance frequency of the dental implant was acquired using Osstell ISQ immediately after dental implant placement and on third-month follow-up. The alveolar bone density around the dental implant was subsequently analyzed using SIDEXIS-XG software. No significant correlation was reported between the alveolar bone density around the dental implant and the resonance frequency of the dental implant (r = -0.102 at baseline, r = 0.146 at follow-up, p > 0.05). However, the alveolar bone density and resonance frequency showed a significant difference throughout the healing period (p = 0.005 and p = 0.000, respectively). Conclusion: Digital dental radiographs and Osstell ISQ showed excellent objectivity and reproducibility in quantifying dental implant stability. Nonetheless, no significant correlation was observed between the results obtained using these two methods.

The assessment of influence of silver-free, fluor releasing dental materials on dental plaque bacteria quantity. 17 patients were included into the study. 51 restorations were placed following manufacturers recommendations. Following materials were used: conventional glassionomer Ketac-Molar ESPE, resin modified glassionomer Fuji II LC GC and fluor containing composite Charisma Heraeus Kulzer Class V restorations were placed in following teeth of upper and lower jaw: canines, first bicuspids, second bicuspids. Sound enamel was a control. After 10 weeks the 72 hours old dental plaque was collected from surface of restorations and control using sterile probe. Total amount of 68 dental plaques were investigated. Each plaque was placed on scaled and sterile aluminum foil. The moist weight of dental plaque was scaled. Dental plaque was moved into 7 ml 0.85% NaCl solution reduced by cystein chlorine hydrogen and disintegrated by ultrasounds (power:100 Watt, wave amplitude: 5 micorm). The suspension of dental plaque was serially diluted from 10(-4) to 10(-5) in sterile 0,85% NaCl solution, and seeded with amount of 0.1 ml on appropriate base. In dental plaque trials the amount of cariogenic bacteria was calculated--Streptococcus mutans, Streptococcus, Lactobacillus, Veillonella and Neisseria, and also total amount of aerobic and anaerobic bacteria was measured. Microbiologic studies were performed in Institute of Microbiology, Medical University, Łódź. Statistical analysis of collected data was accomplished. In 72 hours old dental plaques collected from the surfaces of Ketac -Molar, Fuji II LC, Charisma after 10 weeks since being placed into the class V cavity, results show no statistically significant differences in the amount of Streptococcus mutans, Streptococcus spp., Lactobacillus spp., Veillonella spp., Neisseria spp, in total amount of aerobic and anaerobic bacteria and in the quantity proportion of Streptococcus mutans versus Streptococcus spp. in comparison

2018-02-01

To examine the amount of heterogeneity in patients' preferences for dental care, what factors affect their preferences, and how much they would be willing to pay for improvement in specific dental care attributes. A discrete choice experiment (DCE) was used to elicit patients' preferences. Three alternative dental care services that differed in the type of care provider, treatment explanation, dental staff behavior, waiting time and treatment cost were described to patients. Patients (n=265) were asked to choose their preferred alternative. The study was conducted at a public dental clinic of the School of Dental Medicine, University of Zagreb. Mixed logit and latent class models were used for analysis. On average, the patients would be willing to pay €45 for getting a detailed explanation of treatment over no explanation. This was the most valued attribute of dental care, followed by dental staff behavior with marginal willingness-to-pay (WTP) of €28. Dental care provided by the faculty members and private dental care were valued similarly, while student-provided care was valued €23 less. Patients also disliked longer waiting time in the office, but this was the least important attribute. Four classes of patients with distinct preferences for dental care were identified. Older and/or more educated patients tended to give relatively less importance to treatment explanation. Higher education was also associated with a higher propensity to substitute faculty dental care with the private care providers. Large heterogeneity in patients' preferences was detected. Understanding their preferences may improve the delivery of dental care. Dental care providers should pay particular attention to providing a detailed treatment explanation to their patients. Dental care for older and/or more educated patients should be more attentive to interpersonal characteristics. Faculty dental care provided by faculty members could be price competitive to private care, and student

Music interventions for dental anxiety.

Science.gov (United States)

Bradt, J; Teague, A

2018-04-01

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.

Strategies to manage patients with dental anxiety and dental phobia: literature review

Directory of Open Access Journals (Sweden)

Appukuttan DP

2016-03-01

Full Text Available Deva Priya Appukuttan Department of Periodontics, Sri Ramakrishna Mission Dental College and Hospital, Chennai, India Abstract: Dental anxiety and phobia result in avoidance of dental care. It is a frequently encountered problem in dental offices. Formulating acceptable evidence-based therapies for such patients is essential, or else they can be a considerable source of stress for the dentist. These patients need to be identified at the earliest opportunity and their concerns addressed. The initial interaction between the dentist and the patient can reveal the presence of anxiety, fear, and phobia. In such situations, subjective evaluation by interviews and self-reporting on fear and anxiety scales and objective assessment of blood pressure, pulse rate, pulse oximetry, finger temperature, and galvanic skin response can greatly enhance the diagnosis and enable categorization of these individuals as mildly, moderately, or highly anxious or dental phobics. Broadly, dental anxiety can be managed by psychotherapeutic interventions, pharmacological interventions, or a combination of both, depending on the level of dental anxiety, patient characteristics, and clinical situations. Psychotherapeutic interventions are either behaviorally or cognitively oriented. Pharmacologically, these patients can be managed using either sedation or general anesthesia. Behavior-modification therapies aim to change unacceptable behaviors through learning, and involve muscle relaxation and relaxation breathing, along with guided imagery and physiological monitoring using biofeedback, hypnosis, acupuncture, distraction, positive reinforcement, stop-signaling, and exposure-based treatments, such as systematic desensitization, “tell-show-do”, and modeling. Cognitive strategies aim to alter and restructure the content of negative cognitions and enhance control over the negative thoughts. Cognitive behavior therapy is a combination of behavior therapy and cognitive therapy

Clinical use of dental classification.

Science.gov (United States)

Jones, Gordon

2008-01-01

The Dental Classification system used by the uniformed services is supposed to predict the incidence of dental emergencies in the operational setting, at least on the unit level. Since most Sailors and Marines are deployed without close dental support, the sea services have adopted a policy of early treatment of class 3 dental conditions during recruit training. The other services are beginning to do the same. Recently, two factors have emerged that are affecting this early dental class 3 treatment. These factors must be considered when planning to provide early dental treatment. First, changing population and dentist provider demographics in the civilian sector are beginning to affect the class 3 treatment needs of incoming military recruits. Second, attrition from recruit training results in treatment provided to recruits who leave military service before finishing their training. Some view this as a waste of resources, others as a cost of doing business. As operational jointness increases, the three services must develop and use a single dental classification terminology, as well as unified standards and guidelines, both for better research in this area and for the readiness and well-being of our patients.

Oral Health, Dental Insurance and Dental Service use in Australia.

Srivastava, Preety; Chen, Gang; Harris, Anthony

2017-01-01

This study uses data from the 2004-2006 Australian National Survey of Adult Oral Health and a simultaneous equation framework to investigate the interrelationships between dental health, private dental insurance and the use of dental services. The results show that insurance participation is influenced by social and demographic factors, health and health behaviours. In turn, these factors affect the use of dental services, both directly and through insurance participation. Our findings confirm that affordability is a major barrier to visiting the dentist for oral health maintenance and treatment. Our results suggest that having supplementary insurance is associated with some 56 percentage points higher probability of seeing the dentist in the general population. For those who did not have private insurance cover, we predict that conditional on them facing the same insurance conditions, on average, having insurance would increase their visits to the dentist by 43 percentage points. The uninsured in the survey have lower income, worse oral health and lower rates of preventive and treatment visits. Copyright © 2015 John Wiley & Sons, Ltd. Copyright © 2015 John Wiley & Sons, Ltd.

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.

The aim of this study is to assess the dental esthetics awareness among dental students in a private university in Chennai as none is available in Chennai, Tamil Nadu. The dental esthetics awareness questionnaire consisting of a battery of 19 questions under five aspects that is, physical, functional, social, knowledge, and psychological aspects was administered to a sample of 100 dental college students aged between 18 and 27 years in a private college in Chennai, India. Gender variations on the responses of their effects and the impact on dental esthetics awareness had been analyzed using a Chi-square test. With respect to physical aspects, pigmentation shows more significance as students want to get treated for their pigmentation of lips and gums. With respect to functional aspects, eating shows more significance as students have difficulty while eating. In social aspects, habits show more significance as it affects their esthetics. With respect to psychological aspects, mental depression shows more significance as students feel more deprived due to their unesthetic appearance. This study shows a high level of self-consciousness and the findings of the studies prove that even the slightest of variations have a greater impact on the above-mentioned dimensions in particular to psychological, functional, and physical aspects.

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

Medical-dental collaboration is essential for improving resource efficiency and standards of care. However, few studies have been conducted on it. This study aimed to investigate the attitude and awareness of medical and dental students about collaboration between medical and dental practices in Hong Kong. All medical and dental students in Hong Kong were invited to complete a questionnaire survey at their universities, hospitals and residential halls. It contained 8 questions designed to elicit their attitudes about the collaboration between medical and dental practice. Students were also asked about their awareness of the collaboration between dentistry and medicine. The questionnaires were directly distributed to medical and dental students. The finished questionnaires were immediately collected by research assistants on site. A total of 1,857 questionnaires were distributed and 809 (44%) were returned. Their mean attitude score (SD) towards medical-dental collaboration was 6.37 (1.44). Most students (77%) were aware of the collaboration between medical and dental practice in Hong Kong. They considered that Ear, Nose & Throat, General Surgery and Family Medicine were the 3 most common medical disciplines which entailed collaboration between medical and dental practice. In this study, the medical and dental students in general demonstrated a good attitude and awareness of the collaboration between medical and dental practice in Hong Kong. This established an essential foundation for fostering medical-dental collaboration, which is vital to improving resource efficiency and standards of care.

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.

Radiographic signs and diagnosis of dental disease

International Nuclear Information System (INIS)

Bellows, J.

1993-01-01

Dental radiographs are critical for the complete assessment and treatment of dental diseases. Dental radiography is commonly used to evaluate congenital dental defects, periodontal disease, orthodontic manipulations, oral tumors, endodontic treatments, oral trauma, and any situation where an abnormality is suspected. Although standard radiographic equipment and film can be used to produce dental radiographs, dental X-ray equipment and film provide superior quality images and greater convenience of animal patient positioning. An understanding of normal dental radiographic anatomy is important when interpreting dental radiographs. Stage III periodontitis is the earliest stage of periodontal disease at which radiographic abnormalities become apparent. Bone loss associated with periodontal disease can be classified as either horizontal or vertical. Periapical radiolucencies can represent granulomas, cysts, or abscesses, whereas periapical radiodensities may represent sclerotic bone or condensing osteitis. Lytic lesions of the bone of the jaw often represent oral neoplasms. Neoplasms also can displace or disrupt teeth in the dental arch. Resorptive lesions can be external or internal and appear as radiolucent areas involving the external surface of the root or the pulp cavity, respectively. Feline dental resorptive lesions, also known as odontoclastic resorptions, are a specific form of dental resorptive lesions unique to cats

The increasing complexity of the dental office environment influences productivity and workflow for dental clinicians. Advances in technology, and with it the range of products needed to provide services, have led to sprawl in operatory setups and the potential for awkward postures for dental clinicians during the delivery of oral health services. Although ergonomics often addresses the prevention of musculoskeletal disorders for specific populations of workers, concepts of workflow and productivity are integral to improved practice in work environments. This article provides suggestions for improving workflow and productivity for dental clinicians. The article applies ergonomic principles to dental practice issues such as equipment and supply management, office design, and workflow management. Implications for improved ergonomic processes and future research are explored.

Dental implant has tried at the early stage in 19th century recovering an oral function and esthetics. Technological revolutions in biochemical and new materials have developed on the remarkable change in the dental implants, nowadays we call the three generation therapy for dental implantology. There are many kinds of methods and techniques in dental implants, however a lot of troublesome complication on the process of surgical phase, construction of prothodontics and prognosis of maintenance care. In the proceedings of this symposium, I would like to propose you how to manage the maintenance care for various kind of dental implants through the methodology and case presentations. Tendenay and future for dental implants The current outlook of dental implant has increasing supply and demand not only dentists but also patients. According to Japanese Welfare Ministry's report in 1987, average missing teeth over sixty years old generations are approximately 42% in accordance with NIDR (U.S.A.) research. They are missed on ten over teeth in full 28th teeth dentitions owing to dental caries and periodontal diseases. Generally speaking, latent implant patients are occupied on the same possibility of needs for dental implants both Japan and U.S.A. Management of maintenance care The patients hardly recognized the importance of plaque control for the maintenance care in the intraoral condition after implantation. Dentists and dental staffs must be instruct patients for importance of plaque removal and control, because they already had forgotten the habit of teeth cleaning, especially in the edenturous conditions. 1) Concept of establishment in oral hygiene. Motivation and instruction for patients include very important factors in dental implants as well as in periodontal diseases. Patients who could not achieve on good oral hygiene levels obtained no good results in the long term observations. To establish good oral hygiene are how to control supra plaque surrounding tissues

Full Text Available Background and Design: Oral lichenoid lesions (OLL are contact stomatitis characterized by white reticular or erosive patches, plaque-like lesions that are clinically and histopathologically indistinguishable from oral lichen planus (OLP. Amalgam dental fillings and dental restoration materials are among the etiologic agents. In the present study, it was aimed to evaluate the standard and dental series patch tests in patients with OLL in comparison to a control group and evaluate our results. Materials and Methods: Thirty-three patients with OLL or OLP and 30 healthy control subjects, who had at least one dental restoration material and/or dental filling, were included in the study. Both groups received standard series and dental patch test and the results were evaluated simultaneously. Results: The most frequent allergens in the dental series patch test in the patient group were palladium chloride (n=4; 12.12% and benzoyl peroxide (n=2, 6.06%. Of the 33 patients with OLL; 8 had positive reaction to allergents in the standard patch test series and 8 had positive reaction in the dental patch test series. There was no significant difference in the rate of patch test reaction to the dental and standard series between the groups. Ten patients were advised to have the dental restoration material removed according to the results of the patch tests. The lesions improved in three patients [removal of all amalgam dental fillings (n=1, replacement of all amalgam dental fillings with an alternative filling material (n=1 and replacement of the dental prosthesis (n=1] following the removal or replacement of the dental restoration material. Conclusion: Dental patch test should be performed in patients with OLL and dental restoration material. Dental filling and/or prosthesis should be removed/replaced if there is a reaction against a dental restoration material-related allergen.

General Health Questionnaire (GHQ12), Maslach Burnout Inventory (MBI), Dental Environment Stress Questionnaire (DES), demographic variables. Questionnaire administered to all students attending first year course. Completed questionnaires sent to central office for processing. Seventy-nine percent of the sampled students responded. Over a third of the students (36%) reported significant psychological distress (morbidity) at the recommended cut-off point (>3 on GHQ). These scores were similar to those reported for medical undergraduates. Twenty-two percent recorded comparatively high scores on emotional exhaustion. A wide variation in these 2 measurements was found across schools (p'sStress levels indicated by the DES were less variable (p>0.5). Some evidence showed that contact with patients and the level of support afforded by living at home may be protective. Higher than expected levels of emotional exhaustion were found in a large sample of first-year undergraduate dental students in Europe.

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.

Dentoalveolar abscess is a serious complication that may arise from untreated dental caries, periodontal disease, pericoronitis and facial fractures. The objective of study was to ascertain the dental visit pattern and awareness of dental treatment among patients attending a secondary oral health facility in Benin-City with dentoalveolar abscess. A total of 50 patients that presented with dentoalveolar abscess in the Dental Clinic of Central Hospital between September, 2012 and July, 2013 constituted the study population. Data was collected using unstructured in-depth interview, following a topic guide. Of the 50 patients, 29 (58%) were females, while 21 (42%) were males. Age range was between 3-67 years and the educational status of the patients ranged from illiterate to graduates of tertiary institution. Time interval between onset of pain and presentation of swelling was 1 day to 10 years. Forty-five patients (90%) have heard of dentists. A total of 27 (60%) reported teeth extraction as the only treatment carried out by dentists, 12 (27%) extraction/restoration replacement/treatment and 5 (13%) treatment only. Thirty-seven patients (74%) were first time clinic attendees, 7 (14%) were second time clinic attendees and 6 (12%) were three times and more clinic attendees. This study revealed that patients attending secondary oral health facility with dentoalveolar abscess were dominantly first time dental clinic attendees and exhibited low awareness of treatments offered by dentists. There is need to further investigate the barriers to preventive visits and to improve of awareness of dental treatment among previous dental clinic attendees.

Full Text Available Purpose: Sensitization to metals is a significant problem for both dental patients treated with dental materials and for dental professionals in occupational exposures. The purpose of the present study was to evaluate the incidence of concurrent contact sensitization to relevant for dental practice metals among students of dental medicine, students from dental technician school, dental professionals and patients. Material and Methods: A total of 128 participants were included in the study. All of them were patch-tested with nickel, cobalt, copper, potassium dichromate, palladium, aluminium, gold and tin. The results were subject to statistical analysis (p < 0.05. Results: For the whole studied population, potassium dichromate exhibited concomitant reactivity most often; copper and tin also often manifested co-reactivity. For the groups, exposed in dental practice, potassium dichromate and tin were outlined as the most often co-reacting metal allergens, but statistical significance concerning the co-sensitization to copper and the other metals was established only for aluminium. An increased incidence and OR for concomitant sensitization to cobalt and nickel was established in the group of dental students; to copper and nickel - in the control group; to palladium and nickel - in the group of dental professionals, the group of students of dental medicine and in the control group; to potassium dichromate and cobalt - in the group of dental students; to copper and palladium - in the control group of dental patients; to potassium dichromate and copper - in the group of dental professionals; to copper and aluminum - in the groups of students from dental technician school and of dental professionals; to copper and gold - in the groups of dental professionals and in the group of dental patients; to potassium dichromate and aluminum - in the group of dental professionals; to potassium dichromate and gold - in the group of dental professionals, and to

The aim of this study was to evaluate the use of the dental school admissions interview score as a noncognitive indicator of performance in predoctoral dental education, with specific attention to whether a correlation existed between the admissions interview scores and performance on the objective structured clinical examination (OSCE). The study population consisted of all 175 students in the Harvard School of Dental Medicine (HSDM) DMD Classes of 2012 through 2016. Data on students' gender and age on entering dental school were self-reported using their applications for admission to the HSDM DMD program. Data on students' OSCE scores for three examination sessions were collected from the Office of Dental Education. The results showed that the students' interview scores did not significantly correlate with OSCE performance on any of the three exams. Performance on the first and second OSCEs did, however, correlate with performance on the third OSCE (pinterview score. These results suggest that although the admissions interview scores can serve as an important resource in student selection, with the lack of association between interview and OSCE scores, it is possible that the communication skills required for the interview do not directly overlap with those required for OSCE success.

2016-08-01

This was to investigate the perception of general dental practitioners (GDPs), specialist dentists and dental students regarding the prevalence, severity and aetiological factors of molar incisor hypomineralisation (MIH). Questionnaires were distributed to 407 general and specialist dentists who were members of the Saudi Dental Association and 222 fourth and fifth year dental students at College of Dentistry, King Saud University, Riyadh. The questionnaires investigated the perception and knowledge of MIH, including clinical experience, treatment, views on aetiology and need for further training in management of MIH. A total of 230 (56.5 %) dental practitioners and 149 (67.1 %) dental students completed the questionnaire. The majority of GDPs (76.9 %) and specialists (86.3 %) had encountered MIH in their practice. The majority of specialist dentists (56.1 %) and GDPs (60.4 %) reported that MIH could come second to dental caries as a public health concern. A range of possible aetiological factors were identified by both students and dentists with genetics the most common. The majority of GDPs (90.5 %) and specialists (72.4 %) reported a need for further training in MIH, in particular, regarding treatment. The majority of dental students (64 %) had not heard of MIH and most were in favour of including MIH-associated cases in the undergraduate curriculum of paediatric dentistry. Students were more likely to request training in diagnosis than treatment. MIH is a condition encountered by Saudi dentists who advocated the need for clinical training regarding MIH-aetiological and therapeutic fields. Students have little exposure to MIH and are likely to have similar concerns upon commencement of dental practice.

This study sought to determine whether the self-perceived image of a young adult's anterior dental esthetics is linked with periodontal health, dental caries, and oral hygiene practices. Two hundred subjects were assessed via a clinical examination, including intraoral photographs. The subjects were questioned about their demographics and oral hygiene practices and given the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) to measure their self-perceived variables related to dental esthetics. A high PIDAQ score indicates a negative image of one's own dental esthetics, while a low PIDAQ score indicates a positive outlook. A self-perceived negative psychosocial impact of anterior dental esthetics was detected in subjects with higher levels of dental caries and visible gingival inflammation in the anterior region of the mouth.

Full Text Available Abstract Background Dental caries, dental pain and reported oral problems influence people's oral quality of life and thus their perceived need for dental care. So far there is scant information as to the psychosocial impacts of dental diseases and the perceived treatment need in child populations of sub-Saharan Africa. Objectives Focusing on primary school students in Kilwa, Tanzania, a district deprived of dental services and with low fluoride concentration in drinking water, this study aimed to assess the prevalence of dental pain and oral impacts on daily performances (OIDP, and to describe the distribution of OIDP by socio-demographics, dental caries, dental pain and reported oral problems. The relationship of perceived need estimates with OIDP was also investigated. Methods A cross-sectional study was conducted in 2008. A total of 1745 students (mean age 13.8 yr, sd = 1.67 completed an extensive personal interview and under-went clinical examination. The impacts on daily performances were assessed using a Kiswahili version of the Child-OIDP instrument and caries experience was recorded using WHO (1997 criteria. Results A total of 36.2% (41.3% urban and 31.4% rural, p Conclusion Substantial proportions of students suffered from untreated dental caries, oral impacts on daily performances and perceived need for dental care. Dental pain and reported oral problems varied systematically with OIDP across the eight impacts considered. Eating and tooth cleaning problems discriminated between subjects who perceived need for dental treatment and those who did not.

In South Korea, the number of cases of dental treatment for the disabled is gradually increasing, primarily at regional dental clinics for the disabled. This study investigated pediatric patients at a treatment clinic for the disabled within a university hospital who received dental treatment under general anesthesia. This data could assist those that provide dental treatment for the disabled and guide future treatment directions and new policies. This study was a retrospective analysis of 263 cases in which patients received dental treatment under general anesthesia from January 2011 to May 2016. The variables examined were gender, age, reason for anesthesia, type of disability, time under anesthesia, duration of treatment, type of procedure, treatment details, and annual trends in the use of general anesthesia. Among pediatric patients with disabilities who received dental treatment under general anesthesia, the most prevalent age group was 5-8 years old (124 patients, 47.1%), and the primary reason for administering anesthesia was dental anxiety or phobia. The mean time under anesthesia was 132.7 ± 77.6 min, and the mean duration of treatment was 101.9 ± 71.2 min. The most common type of treatment was restoration, accounting for 158 of the 380 treatments performed. Due to increasing demand, the number of cases of dental treatment performed under general anesthesia is expected to continue increasing, and it can be a useful method of treatment in patients with dental anxiety or phobia.

Austin, R. S.; Mullen, F.; Bartlett, D. W.

2015-06-01

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 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 red...

The purpose of this study was to determine if changes in dental development are associated with Attention Deficit Hyperactivity Disorder (ADHD) or ADHD medications. This retrospective chart review evaluated the dental age of 128 patients between 6 and 16 years of age using the Demirjian method from the following two groups a) children with ADHD b) unaffected children. The ADHD group was further stratified into four groups according to the medication type. The impact of ADHD on dental age difference (the difference between dental age and chronologic age) was analyzed using T-test and the association between medication type and dental age difference was analyzed through one way ANOVA. The mean difference between estimated dental age and chronologic age (dental age difference) for all subjects was 0.80 years. There was no significant dental age difference in subjects with ADHD and the control group (0.78±1.28vs. 0.84 ±1.09 years respectively; P=0.75) and there was no significant difference in dental age difference and type of medication (P=0.84). No significant difference was found between children with ADHD and unaffected children with respect to dental age difference. No significant differences were found in dental age difference in the four medication groups.

Full Text Available Introduction: Dental anxiety is an abnormal fear or dread of visiting the dentist for preventive care or therapy and unwarranted anxiety over dental procedures. It is a common problem that affects people of all ages and appears to develop mostly in childhood and adolescence. The present study assesses dental anxiety among children in a nonclinical setting among Saudi Arabian children who underwent preventive treatment procedure using Abeer Children Dental Anxiety Scale (ACDAS. Materials and Methods: The children attending an oral health program were screened for oral health problems and preventive treatment such as topical fluoride applications. The dental anxiety among children was assessed using ACDAS. Results: A total of 51 children participated in the research. The results showed that maximum children were not scared of dentist in nonclinical setting and had low dental anxiety levels. Overall, 74% of the child subjects had ACDAS scores below 26. Conclusions: Knowing the degree of anxiety of dental children is important to guide them through their dental experience and carry on the preventive dental treatments at an early age in nonclinical setting. Their level of cooperation will improve, and anxiety will be reduced as well. Further research is required to compare dental anxiety levels in children between clinical and nonclinical setting.

Wnt and BMP signaling crosstalk in regulating dental stem cells: Implications in dental tissue engineering

Full Text Available Tooth is a complex hard tissue organ and consists of multiple cell types that are regulated by important signaling pathways such as Wnt and BMP signaling. Serious injuries and/or loss of tooth or periodontal tissues may significantly impact aesthetic appearance, essential oral functions and the quality of life. Regenerative dentistry holds great promise in treating oral/dental disorders. The past decade has witnessed a rapid expansion of our understanding of the biological features of dental stem cells, along with the signaling mechanisms governing stem cell self-renewal and differentiation. In this review, we first summarize the biological characteristics of seven types of dental stem cells, including dental pulp stem cells, stem cells from apical papilla, stem cells from human exfoliated deciduous teeth, dental follicle precursor cells, periodontal ligament stem cells, alveolar bone-derived mesenchymal stem cells (MSCs, and MSCs from gingiva. We then focus on how these stem cells are regulated by bone morphogenetic protein (BMP and/or Wnt signaling by examining the interplays between these pathways. Lastly, we analyze the current status of dental tissue engineering strategies that utilize oral/dental stem cells by harnessing the interplays between BMP and Wnt pathways. We also highlight the challenges that must be addressed before the dental stem cells may reach any clinical applications. Thus, we can expect to witness significant progresses to be made in regenerative dentistry in the coming decade.

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.

Taxonomy for competency-based dental curricula.

Beltrán-Neira, Roberto J; Beltrán-Aguilar, Eugenio D

2004-09-01

The objective of this article is to propose a classification of dental competencies. Interest in dental competencies has grown consistently during the last three decades. However, the dental education literature suggests that the term "competency" is understood and used differently by dental schools around the world. The taxonomic classification of dental competencies we propose follows a systematic approach starting at the highest level of complexity, i.e., the professional profile the teaching institution envisions for its graduates, and following in a decreasing degree of complexity to competency function, task, step, movement, and moment. This taxonomy has proved to be useful for more than thirty years in the Dental School of the Peruvian University Cayetano Heredia. Graduates of this school are successful practitioners, teachers, and researchers in Peru and other countries. The classification proposed here should clarify terms, facilitate curriculum design and learning assessment, stimulate further discussion on the matter, and facilitate communication among the dental education establishment.

State-sponsored dental terrorism?

Has the state's manipulation of the NHS dental contract systems deliberately, or accidentally, had corrupting effects on the behaviours of some members of the dental profession? If the answer is 'possibly' or 'probably', then obvious questions that follow include, 'was this done deliberately' and if so, 'why'? Could this have been done for largely altruistic reasons, or was it done to achieve government control for minimum cost? Might this have been undertaken for political, financial or ideological reasons - regardless of any adverse longer term consequences for some patients or for some dental professionals? Might it have been done to take greater control of the dental profession on the grounds that all professions are a conspiracy against the laity, as the mildly paranoid George Bernard Shaw once alleged? Is it possible that some of this manipulation might have been done to help to disempower yet another profession, allegedly to 'modernise it', but perhaps to enslave it for its own reasons? Was this just another example of some statist politicians wanting to interfere in all aspects of UK society, regardless of their lack of specific understanding, or any proven expertise, in many areas? Could the state's manipulation of contracts and processes be regarded as an abuse of power by a virtual monopoly, which has been used to control a largely altruistic profession by imposing corrupting NHS dental contract systems with the most recent one involving 'units of dental activity' (UDAs)? Perhaps it was really about some politicians wanting ever more power, control or money - their usual drivers - with the dental and medical professions accidentally becoming casualties?

Shortened dental arches consisting of anterior and premolar teeth have been shown to meet oral functional demands. However, the occlusal stability may be at risk as a result of tooth migration. The aim of this nine-year study was to investigate occlusal stability in shortened dental arches as a function over time. Occlusal stability indicators were: 'interdental spacing', 'occlusal contacts of anterior teeth in Intercuspal Position', 'overbite', 'occlusal tooth wear', and 'alveolar bone support'. Subjects with shortened dental arches (n = 74) were compared with subjects with complete dental arches (controls, n = 72). Repeated-measurement regression analyses were applied to assess age-dependent variables in the controls and to relate the occlusal changes to the period of time since the treatment that led to the shortened dental arches. Compared with complete dental arches, shortened dental arches had similar overbite and occlusal tooth wear. They showed more interdental spacing in the premolar regions, more anterior teeth in occlusal contact, and lower alveolar bone scores. Since the differences remained constant over time, we conclude that shortened dental arches can provide long-term occlusal stability. Occlusal changes were self-limiting, indicating a new occlusal equilibrium.

Some socio-medical aspects of preventive and curative dental care. Preventive and early curative dental care is considered as an integral part of general health behavior in the individual. Different variables possibly determining such behavior are discussed. Demographic factors as age, sex, place of residence, as well as family and educational background, income and vocation seem to be of importance. A dental health delivery system free of charge to everyone in the age group 6-18, eventually up to 21 years has been available for several years in Norway. We assume that this has had a great impact upon the motivations for a positive atitude towards preventive care, particularly since economic barriers have been reduced simultaneously with shift in the popular value aspects of having good dental health status. Plans for a future incorporation of dental care into a total national health service, comprising the entire population, in order to make the delivery system feasible for everyone, will probably stimulate a still wider interest and motivation for preventive and early dental care.

Full Text Available Objectives: To explore the rate of pneumoconiosis in dental technicians (DTP and to evaluate the risk factors. Material and Methods: Data of 893 dental technicians, who were admitted to our hospital in the period January 2007–May 2012, from 170 dental laboratories were retrospectively examined. Demographic data, respiratory symptoms, smoking status, work duration, working fields, exposure to sandblasting, physical examination findings, chest radiographs, pulmonary function tests and high-resolution computed tomography results were evaluated. Results: Dental technicians’ pneumoconiosis rate was 10.1% among 893 cases. The disease was more common among males and in those exposed to sandblasting who had 77-fold higher risk of DTP. The highest profusion subcategory was 3/+ (according to the International Labour Organization (ILO 2011 standards and the large opacity rate was 13.3%. Conclusions: To the best of our knowledge, it was the largest DTP case series (N = 893/90 in the literature in English. Health screenings should be performed regularly for the early diagnosis of pneumoconiosis, which is an important occupational disease for dental technicians.

We determined the association between timing of a first dentist office visit before age 5 years and dental disease in kindergarten. We used North Carolina Medicaid claims (1999-2006) linked to state oral health surveillance data to compare caries experience for kindergarten students (2005-2006) who had a visit before age 60 months (n=11,394) to derive overall exposure effects from a zero-inflated negative binomial regression model. We repeated the analysis separately for children who had preventive and tertiary visits. Children who had a visit at age 37 to 48 and 49 to 60 months had significantly less disease than children with a visit by age 24 months (incidence rate ratio [IRR]=0.88; 95% confidence interval [CI]=0.81, 0.95; IRR=0.75; 95% CI=0.69, 0.82, respectively). Disease status did not differ between children who had a tertiary visit by age 24 months and other children. Medicaid-enrolled children in our study followed an urgent care type of utilization, and access to dental care was limited. Children at high risk for dental disease should be given priority for a preventive dental visit before age 3 years.

Full Text Available El periodo gestacional se relaciona con una mayor incidencia de caries dental, aunque la asociación entre gestación e incremento de caries no ha podido aún ser científicamente demostrada. Se propuso realizar un estudio para determinar la presencia de caries dental y algunos factores de riesgo asociados en el primer y tercer trimestre del embarazo, para detectar la aparición de lesiones cariosas nuevas y cambios relacionados con los factores de riesgo entre ambos trimestres. Se realizó un estudio descriptivo longitudinal desde diciembre de 2006 a febrero de 2008 en el municipio de Florida, Camagüey, Cuba. El universo de estudio estuvo constituido por 38 embarazadas y la muestra por 21, que fueron interrogadas y examinadas en ambos trimestres con el objetivo de determinar la presencia de caries y los factores de riesgo asociados como: higiene bucal deficiente, dieta cariogénica, pH salival bajo, ocurrencia de vómitos y embarazo previo. La información necesaria fue recogida en un formulario confeccionado al efecto. En el primer trimestre el 80,95 % estaban afectadas por caries dental y se observó aparición de lesiones nuevas en 6 embarazadas, en el tercer trimestre. Los factores de riesgo presentados con mayor frecuencia en el primer trimestre fueron la dieta cariogénica en el 66,66 % y la higiene bucal deficiente en el 47,61 % de las pacientes. Ninguna embarazada modificó la dieta durante el embarazo, sin embargo la higiene bucal deficiente persistió en el 14,28 %. El 52,38 % de las embarazadas afectadas en el primer trimestre consumían dieta cariogénica y el 47,61 % habían tenido embarazo previo. Se concluyó que hubo afectación por nuevas caries durante el embarazo, los factores de riesgo que predominantes fueron la dieta cariogénica, la higiene bucal deficiente y el embarazo previo. Las pacientes no modificaron la dieta durante el embarazo, pero sí mejoraron la higiene bucal. Todas las que presentaban vómitos y pH salival

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.

To ascertain whether interdental cleaning behaviours of Australian adults were associated with lower levels of plaque, gingivitis and periodontal disease. Data were obtained from the National Survey of Adult Oral Health 2004-06. Outcome variables were three indicators of oral hygiene outcomes (the presence or not of dental plaque, dental calculus and gingivitis) and two of periodontal disease (the presence or not of at least one tooth with a periodontal pocket or clinical attachment loss of ≥ 4 mm). The independent variable was classified into the following three groups: regularly clean interproximally 'at least daily' (daily+); 'less than daily' (dental plaque (dental calculus (dental plaque and gingivitis, although there was no significant association between regular interdental cleaning and clinical attachment loss. © 2011 John Wiley & Sons A/S.

Hunter-gatherer dental pathology: Do historic accounts of Aboriginal Australians correspond to the archeological record of dental disease?

2018-03-01

Studies of hunter-gatherer oral pathology, particularly in Australia, often focus upon dental wear and caries or assume that historic studies of Aboriginal people reflect the precontact past. Consequently the range of population variation has been underestimated. In this paper dental pathology from human remains from Roonka are compared with a model of dental pathology derived from historic studies. The aim is to identify aspects of dental pathology indicative of regional or intra-population diversity. Adult dentitions (n = 115) dating from the mid to late Holocene were recorded for the following conditions: dental wear, caries, periapical voids, calculus, periodontal disease and antemortem tooth loss. Statistical analysis was used to identify patterns of dental pathology and to identify causal relationships between conditions. Dental wear is marked while dental caries rates are extremely low. Other indications of dental pathology are uncommon (<7% of teeth affected). Temporal heterogeneity is apparent: there are 3 young adults with caries who died in the postcontact period. There is also a small group of middle age to old adults with disproportionate abscessing and pulp exposure who may represent temporal variation or heterogeneity in individual frailty. The results confirm dental wear as the major cause of dental pathology in this group and that, at a general level, historic accounts do correspond with this archeological sample. However, intra-sample heterogeneity is apparent while 2 dental conditions, calculus and periodontal disease, along with the pattern of sex differences deviate from expectation, demonstrating that to identify regional variation attention needs to be paid to the dentoalveolar complex as a whole. © 2017 Wiley Periodicals, Inc.

Recently, there has been increased attention to including cultural diversity in the education of health professionals, including concern for lesbian, gay, bisexual, and transgender (LGBT) inclusion and visibility. Studies regarding cultural exposure and acceptance of LGBT populations have been concentrated in medicine, with findings showing that medical providers often graduate having missed the preparation required to care for LGBT persons. A visible, comprehensive, culturally competent environment in dental schools would help ensure that all oral health professionals and students are aware of services available to address the particular needs of LGBT students. The aims of this survey-based study conducted in 2015-16 were to determine dental students' perceptions regarding LGBT students' needs and to assess dental students' knowledge of resources for LGBT persons at three U.S. dental schools, one each in the Midwest, West, and South. Of the 849 students invited to participate, 364 completed the survey (338 dental, 26 dental hygiene), for an overall response rate of 43%. The response rate at individual schools ranged from 30% to 55%. The results showed perceptions of insufficient LGBT information, resources, and support at these institutions, especially at the Western school. There were significant differences among the three schools, with students at the Western school more than the other two schools perceiving that their institution was less aware of whether it met the academic, social support, and spiritual needs of LGBT students. There were no significant differences between LGBT and non-LGBT students' perceptions. The authors urge dental school administrators to explore the degree to which their programs teach respectful and caring behavior towards LGBT students and, by extension, LGBT patient populations.

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 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.

Effect of thickener agents on dental enamel microhardness submitted to at-home bleaching Efeito de agentes espessantes na microdureza do esmalte submetido ao clareamento dental caseiro

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.

Purpose: To establish a new method for dental imaging using magnetic resonance tomography named Dental-MRT and to demonstrate its usefulness in diagnosing dentogen pathologies of the mandible and maxilla. Methods: Seven healthy volunteers, three patients with pulpitis, two patients with dentigerous cysts, two patients after tooth transplantation, and three patients with atrophic mandibles have been evaluated. Optimized axial T 1 - and T 2 -weighted gradient echo and spin echo sequences in 2D and 3D technique have been established to perform studies of the jaws. The acquired images were reconstructed with a standard dental software package on a workstation as panorama and cross-sectional views of the mandible or maxilla. Results: The entire maxillo-mandibular bone, teeth, dental pulp, and the content of the mandibular canal were well depicted. Patients with pulpitis demonstrate bone marrow edema in the periapical region. Dentigerous cysts and their relation to the surrounding structures are clearly shown. After contrast media administration marked enhancement of the dental pulp can be demonstrated. Conclusion: Dental-MRT promises to provide a new tool for visualization and detection of dental diseases. (orig.) [de

A major aspect in evaluating the quality of dental materials is their physical properties. Their properties should be a best fit of the ones of dental hard tissues. Manufacturers give data sheets for each material. The properties listed are characterized by a specific value. This assumes (but does not prove) that there is no direction dependence of the properties. However, dental enamel has direction-dependent properties which additionally vary with location in the tooth. The aim of this paper is to show the local direction dependence of physical properties like the elastic modulus or the thermal expansion in dental hard tissues. With this knowledge the 'perfect filling/dental material' could be characterized. Enamel sections of ∼400-500 μm thickness have been cut with a diamond saw from labial/buccal to palatal/lingual (canine, premolar and molar) and parallel to labial (incisor). Crystallite arrangements have been measured in over 400 data points on all types of teeth with x-ray scattering techniques, known from materials science. X-ray scattering measurements show impressively that dental enamel has a strong direction dependence of its physical properties which also varies with location within the tooth. Dental materials possess only little or no property direction dependence. Therefore, a mismatch was found between enamel and dental materials properties. Since dental materials should possess equal (direction depending) properties, worthwhile properties could be characterized by transferring the directional properties of enamel into a property 'wish list' which future dental materials should fulfil. Hereby the 'perfect dental material' can be characterized.

To present: the normative data on dental fear and caries status; the dental fear cut-off points of young children in the city of Thessaloniki, Greece. Study Design: This is a cross-sectional study with two independent study groups. A first representative sample consisted of 1484 children from 15 primary public schools of Thessaloniki. A second sample consisted of 195 randomly selected age-matched children, all patients of the Postgraduate Paediatric Dental Clinic of Aristotle University of Thessaloniki. First sample: In order to select data on dental fear and caries, dental examination took place in the classroom with disposable mirrors and a penlight. All the children completed the Dental Subscale of the Children's Fear Survey Schedule (CFSS-DS). Second sample: In order to define the cut-off points of the CFSS-DS, dental treatment of the 195 children was performed at the University Clinic. Children⁁s dental fear was assessed using the CFSS-DS and their behaviour during dental treatment was observed by one calibrated examiner using the Venham scale. Statistical analysis of the data was performed with IBM SPSS Statistics 20 at a statistical significance level of fear. Mean differences between boys and girls were not significant. Caries was not correlated with dental fear. Second sample: CFSS-DSfear', scores 33-37 as 'borderline' and scores > 37 as 'dental fear'. In the first sample, 84.6% of the children did not suffer from dental fear (CFSS-DSfear was correlated to age and not to caries and gender. The dental fear cut-off point for the CFSS-DS was estimated at 37 for 6-12 year old children (33-37 borderlines).

It is not known whether the integration of photo-stimulable phosphor (PSP) plates into dental and dental hygiene curricula creates unique learning challenges for students. The purpose of this two-year study was to determine if dental hygiene students had more and/or different types of errors when using PSP plates compared to film and whether the PSP imaging plates had any particular characteristics that needed to be addressed in the learning process. Fifty-nine first-year dental hygiene students at one Canadian dental school were randomly assigned to two groups (PSP or film) before exposing their initial full mouth series on a teaching manikin using the parallel technique. The principal investigator determined the number and types of errors based on a specific set of performance criteria. The two groups (PSP vs. film) were compared for total number and type of errors made. Results of the study indicated the difference in the total number of errors made using PSP or film was not statistically significant; however, there was a difference in the types of errors made, with the PSP group having more horizontal errors than the film group. In addition, the study identified a number of unique characteristics of the PSP plates that required special consideration for teaching this technology.

2012-01-01

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. This review discusses the role of salivary factors on the development of dental erosion. 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. 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. 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.

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%).

During the last few decades, the increasing demands in esthetic dentistry have led to the development of dental composites material that provide similar appearance to the natural teeth. Recently, esthetic trend was an issue which increase the demand for teeth restorations that is similar with the origin. The esthetics of dental composite are more superior compared to amalgam, since its color look similar with natural teeth. Various dental composites have been developed using many type of fillers such as amorphous silica, quartz), borosilicate, Li-Sr-Ba-Al glass and oxide: zirconia and alumina. Researchers in Faculty of Dentistry University of Padjadjaran have prepared dental composites using zirconia-alumina-silica (ZAS) system as the filler. The aim is to improve the mechanical properties and the esthetic of the dental composites. The ZAS was obtained from chemical grade purity chemicals and Indonesia's natural sand as precursors its characterization were also presented. This novel method covers the procedure to synthesis and characterize dental composites in Padjadjaran University and some review about dental composites in global research.

Epigenetic regulation in dental pulp inflammation

2016-01-01

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

Context: Forensic odontology plays a pivotal role in the identification of victims in mass disasters with the help of “Preserved dental records” available with the general dental practitioners (GDPs). However, the status of such dental records of forensic importance has not been studied extensively. Aim: To study the current status of awareness and practice of dental record maintenance by GDPs of Pune. Materials and Methods: A cross-sectional study was conducted among 100 randomly selected GDPs from Pune. Data was collected in a personalized manner by means of a questionnaire. Results: Six percent of GDPs do not maintain any records of the patient, 11% of them do not record about developmental dental anomalies, and 22% GDPs do not retain radiographs. Sixty-seven percent GDPs mention about the use of abbreviations while recording history. Only 17% of GDPs record denture marking and 11% take conformity certificate for the denture. Thirty percent GDPs do not mention the serial number of an implant whereas 17% of them do not mention about the prescribed medication. Five percent GDPs handover original dental record to the patient and 91% said that they discard casts and models immediately after treatment. Conclusion: There was inadequate knowledge and lack of practice regarding proper record maintenance among GDPs. PMID:28584484

Dental caries is one of the most common chronic childhood diseases affecting a large portion of children in the United States. The prevalence of childhood dental caries in Kentucky is among the highest in the nation. The purposes of this study are to (1) compare sociodemographic differences between caries and no caries groups and (2) investigate factors associated with untreated dental caries among children who visited a mobile dental clinic in South Central Kentucky. Study subjects were children aged 6 to 15 years who participated in the school-based dental sealant program through the mobile dental clinic operated by the Institute for Rural Health at Western Kentucky University between September 2006 and May 2011 (n = 2,453). Descriptive statistics were calculated for sociodemographic factors (age, gender, race/ethnicity, insurance status, and urban versus rural residential location) and caries status. We used chi-square tests to compare sociodemographic differences of children stratified by caries and no caries status as well as three levels of caries severity. We developed a logistic regression model to investigate factors associated with untreated dental caries while controlling for sociodemographic characteristics. The proportion of children having untreated dental caries was 49.7% and the mean number of untreated dental caries was 2.0. The proportion of untreated dental caries was higher in older children, children with no insurance and living in rural residential locations, and caries severity was also higher in these groups. Odds ratio indicated that older ages, not having private insurance (having only public, government-sponsored insurance or no insurance at all) and rural residential location were associated with having untreated dental caries after controlling for sociodemographic characteristics of children. Untreated dental caries was more likely to be present in older children living in rural areas without insurance. Health interventionists may use

Dental implant-retained overdentures have been chosen as the treatment of choice for complete mandibular removable dentures. Dental implants, such as mini dental implants, and components for retaining overdentures, are commercially available. However, comparative clinical studies comparing mini dental implants and conventional dental implants using different attachment for implant-retained overdentures have not been well documented. To compare the clinical outcomes of using two mini dental implants with Equator ® attachments, four mini dental implants with Equator attachments, or two conventional dental implants with ball attachments, by means of a randomized clinical trial. Sixty patients received implant-retained mandibular overdentures in the interforaminal region. The patients were divided into three groups. In Groups 1 and 2, two and four mini dental implants, respectively, were placed and immediately loaded by overdentures, using Equator ® attachments. In Group 3, conventional implants were placed. After osseointegration, the implants were loaded by overdentures, using ball attachments. The study distribution was randomized and double-blinded. Outcome measures included changes in radiological peri-implant bone level from surgery to 12 months postinsertion, prosthodontic complications and patient satisfaction. The cumulative survival rate in the three clinical groups after one year was 100%. There was no significant difference (p < 0.05) in clinical results regarding the number (two or four) of mini dental implants with Equator attachments. However, there was a significant difference in marginal bone loss and patient satisfaction between those receiving mini dental implants with Equator attachments and conventional dental implants with ball attachments. The marginal bone resorption in Group 3 was significantly higher than in Groups 1 and 2 (p < 0.05); there were no significant differences between Groups 1 and 2. There was no significant difference in

To determine the self-perceived knowledge and attitudes of general dental practitioners (GDPs) concerning management of dental trauma in primary care. To identify potential barriers to the management of dental trauma in primary care. A self-completion postal questionnaire survey of 417 GDPs in six local health authority districts in northeast England. Likert scale responses to 20 statements designed to test self-perceived knowledge and attitudes. Following descriptive statistical analysis. Factor analysis with principle components analysis was undertaken to identify areas of correlation in questionnaire responses, followed by Chi squared test, Spearman's Rank Correlation and analysis of variance (ANOVA) to measure association between variables. The response rate was 74%. Enamel and dentine fractures were the most common injury, with 45% of GDPs responding seeing more than 10 cases of dental trauma in the preceding year and 53% of respondents seeing one to three cases of complicated crown fracture. Seventy-eight per cent believed that NHS remuneration was inadequate, but only 8% would refer patients with dental trauma to secondary care for this reason. Half of the GDPs believed that trauma could be treated more effectively in practice if NHS payments were greater. GDPs were significantly more likely to agree with this statement if they had previously undertaken a postgraduate course in the treatment of dental trauma (p=0.002). Single handed GDPs were statistically significantly more likely to agree with the statements 'I would not treat dental trauma cases at my practice because the NHS payment is inadequate' (p=0.008) and 'Treating dental trauma at my practice requires too much of my clinical time to be worthwhile' (p=0.002). Ninety-six per cent of GDPs disagreed that treatment of dental trauma rested solely within secondary care. Ninety-six per cent of GDPs agreed that they had a responsibility to provide initial emergency treatment for trauma patients prior to

The aim of this study was to investigate the use of information technology amongst dental students, dental nursing students and resident doctors in training at the faculty of dental Surgery University of Lagos. A structured questionnaire was distributed to 58 clinical dental students in 4 th and 5 th years of training in the 2010/2011 academic year, 36 dental nursing students and 63 resident doctors undergoing specialist training. All participants have access to the computers, 2.5% within the University and 31% at home and internet cafes and about 50% have the basic skills required. A significant difference was observed between the resident doctors and clinical dental students (P = 0.003), between resident doctors and dental nursing students (P = 0.0001) when the use of computer for study was compared. Over 95% of participants have access to internet and about 50% of them use the internet for their studies. A significant difference (P = 0.005) was observed between clinical dental students and dental nursing students that use the internet and word processing. The resident doctors used the computers for multimedia and MedLine search tools more than clinical dental students (P = 0.004) and dental nursing students (0.0006). The findings of the study show that dental students and resident doctors in training have the requisite knowledge to operate the computer for use in their study and personal activities.

However, for this to be effective, gloves should be intact during the entire course of dental procedure. Leaky surgical latex gloves have been seen in 0.9% of cases before use. As much as 1.9% of latex gloves have been reported to be damaged during dental procedures. In this study, we decided to assess glove damage during dental procedures among dental specialists in Tabriz.

Materials and methods. Thirty-six dental specialists were selected for this study. Each practitioner received 40 pairs of intact powdered latex gloves. Upon the completion of dental procedures, the gloves were retrieved and any tears were evaluated separately for right and left hands. Data was analyzed using chi-square test.

Results. 159 punctures were detected in 144 gloves (5% out of 2880 unpaired gloves used by practitioners. They noticed the tear(s in 60 cases (2%, however, 99 cases (3% of tear(s were not noted during the procedure. The highest rate of glove damage was observed in the prosthodontists’ group (12.3%, which was statistically significant comparing to other groups (p=0.048. The lowest rate of the damage was observed in the oral surgeons’ group (2% which showed no significant difference (p=0.134. The highest rate of punctures in the gloves was observed in the first and second fingers of the non-dominant hand.

Conclusion. The damage to 5% of the gloves is highly significant, with a potential role in occupational hazards. The higher rate of leaks in the prosthodontists’ group compared to other groups demands for greater prudence in this field. The high rate of leaks in the first and second fingers of the non-dominant hand requires more attention to this area during daily practice.

Medical emergencies in dental practice.

LENUS (Irish Health Repository)

Wilson, M H

2009-06-01

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.

Recently the micropig has been developed as human disease model. The dental and orofacial region of micropig is similar to that of humans, so it has been used for testing implant materials and techniques. The purpose of this study is on dental image at each age using radiography and computed tomography. Total twenty-two male micropigs, two or three animals of each 1, 3, 5, 7, 9, 12, 18 and 24 months old, were given radiographic examinations. After general anesthesia, extra- and intra-oral radiographic technique and computed tomographic scans were performed to assess the dental characterization of micropigs. The total deciduous dental formula comprised 28 teeth and was depicted as Di 3/3, Dc 1/1, Dp 3/3. The total permanent dental formula comprised 44 teeth and was depicted as I 3/3, C 1/1, P 4/4, M 3/3. Hypodontia of the first premolars was common in the micropig. The permanent teeth erupted from 3 to 24 month after birth. The sequence of eruption of the permanent teeth was M1, P1, I3, C, M2, I1 + P3 + P4, P2, I2, M3. Dental imaging enables visualization of the unerupted teeth and gives more information about the development of the teeth. The growth pattern of the teeth obtained through radiographic and computed tomographic examination provides basic data in the micropig as animal model for dental research

Dental Education in Veterinary Medicine

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.

Dental x-ray validation study: comparison of information from patient interviews and dental charts

International Nuclear Information System (INIS)

1985-01-01

Information was collected from dentists of a subset of participants in a case-control interview study conducted in Los Angeles County, California, in August 1980-August 1981 to evaluate the relationship of dental x-rays to tumors of the parotid gland. Complete dental charts were available from 142 dentists of 84 cases and from 130 dentists of 79 control. Analysis of data from these interview chart comparisons indicates that recall appears to be unbiased since the measures of agreement between interview and dental chart data are similar for cases and controls. The authors further conclude that interview data alone may be used for case-control comparisons of dental x-ray exposure and would, because of unbiased misclassification, tend to underestimate the relative risks. 12 references, 3 tables

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 burs are used extensively in dentistry to mechanically prepare tooth structures for restorations (fillings), yet little has been reported on the bur debris left behind in the teeth, and whether it poses potential health risks to patients. Here it is aimed to image dental bur debris under dental fillings, and allude to the potential health hazards that can be caused by this debris when left in direct contact with the biological surroundings, specifically when the debris is made of a non-biocompatible material. Non-destructive micro-computed tomography using the BioMedical Imaging & Therapy facility 05ID-2 beamline at the Canadian Light Source was pursued at 50 keV and at a pixel size of 4 µm to image dental bur fragments under a composite resin dental filling. The bur's cutting edges that produced the fragment were also chemically analyzed. The technique revealed dental bur fragments of different sizes in different locations on the floor of the prepared surface of the teeth and under the filling, which places them in direct contact with the dentinal tubules and the dentinal fluid circulating within them. Dispersive X-ray spectroscopy elemental analysis of the dental bur edges revealed that the fragments are made of tungsten carbide-cobalt, which is bio-incompatible.

Advocacy for the Provision of Dental Hygiene Services Within the Hospital Setting: Development of a Dental Hygiene Student Rotation.

Educational preparation of dental hygiene students for hospital-based practice, and advocacy efforts promote inclusion of dental hygienists within hospital-based interdisciplinary health care teams. Although the value of attending to the oral care needs of patients in critical care units has been recognized, the potential impact of optimal oral health care for the general hospital population is now gaining attention. This article describes a hospital-based educational experience for dental hygiene students and provides advocacy strategies for inclusion of dental hygienists within the hospital interdisciplinary team. The dental hygienist authors, both educators committed to evidence-based oral health care and the profession of dental hygiene, studied hospital health care and recognized a critical void in oral health care provision within that setting. They collaboratively developed and implemented a hospital-based rotation within the curriculum of a dental hygiene educational program and used advocacy skills to encourage hospital administrators to include a dental hygiene presence within hospital-based care teams. Hospital-based dental hygiene practice, as part of interprofessional health care delivery, has the potential to improve patient well-being, shorten hospital stays, and provide fiscal savings for patients, institutions, and third party payers. Advocacy efforts can promote dental hygienists as members of hospital-based health care teams. Further research is needed to document: (1) patient outcomes resulting from optimal oral care provision in hospitals; (2) best ways to prepare dental hygienists for career opportunities within hospitals and other similar health care settings; and (3) most effective advocacy strategies to promote inclusion of dental hygienists within care teams.

Behbehani, J M

2003-01-01

For a long time there has been a need to establish a dental school in Kuwait, due to the fact that the majority of dentists working in Kuwait are expatriates from various countries. An Amiri decree in 1996 made it possible, and the first dental students were admitted to the Kuwait University Faculty of Dentistry in 1998. The mission of the Faculty of Dentistry is 'to promote oral health in Kuwait through education, research and cooperation with other professional health care institutions as well as the community at large'. A 6.5-year dental curriculum was completed after 2 years of committee work and was accepted by the University Council in 2001. This curriculum incorporates current trends in medical and dental education, such as the evidence-based and community-based approaches, problem-solving methodology for outcome-based learning, and competency achieved through comprehensive patient care.
