    Full Text Available Las colecciones científicas desempeñan un papel fundamental en la acumulación del conocimiento biológico. Recientemente, el uso de fototrampas para realizar inventarios y estudios ecológicos en mamíferos se ha incrementando notablemente. Sin embargo, la información básica asociada a las imágenes no se ha organizado de manera formal y sistemática, como en el caso de los especímenes en una colección científica. Aquí, se propone un formato para producir fichas digitales de fotocolecta en donde la imagen de la especie fotografiada esté asociada a la misma información básica que se registra en una colecta tradicional, lo que permitirá que éstas sean fácilmente incluidas en colecciones científicas, con lo que se documentará la información disponible proveniente de todos aquellos sitios que actualmente estén monitoreándose mediante este método.The main objective of biological collections is to accumulate biological data. The use of camera-traps for inventories and ecological studies of mammals has shown a noteworthy recent increase. However, the basic information associated with the images is not organized in a formal or systematic way, like the specimens of a scientific collection. Here, we propose a format to produce digital photosampling cards where the image of the photographed species is associated with the same basic information that is recorded for a traditional sample; in this way, they can be easily inorporated in scientific collections, thus documenting the available information for the sites that are sampled by this method.

    2012-12-01

    Full Text Available Los dientes proveen información valiosa que ayuda a identificar a una persona con los métodos propios de la odontología legal y forense. A nivel penitenciario, el expediente del interno, al ser un documento de identidad del infractor, deberá integrar toda la información posible que permita a las autoridades judiciales cerciorarse de que se trata de la misma persona registrada, ya sea en calidad de procesado o sentenciado, con todas sus características físicas posibles en las denominadas fichas antropométricas, con el propósito de evitar suplantaciones o errores en la imposición de las penas a delincuentes. Sin embargo, en México, al efectuar una revisión de las leyes actuales, iniciativas o reformas en la materia (tanto estatales como federales, sobre el registro de internos y la conformación de sus expedientes, no hay una homologación sobre los datos que debe contener la ficha antropométrica; mucho menos, en ningún apartado o sección de dicho documento, se considera la ficha estomatológica como medio de identificación. En el presente artículo se exponen las razones por las cuales debe incluirse en los centros penitenciarios de México la ficha de identificación estomatológica, puesto que también tal registro odontológico es una opción de control para procesados y sentenciados, y no solo un potencial documento para cotejar en el caso de infractores reincidentes o fallecidos.

    Full Text Available El conocimiento de los factores de riesgo de la fluorosis dental es importante para disminuir la prevalencia de esta enfermedad. Determinar su severidad y evaluar los factores de riesgo asociados fue el objetivo de esta investigación, para lo cual se realizó un estudio descriptivo en los consultorios 46 y 64 de la zona rural de Ingenio Viejo, del municipio de Camagüey, en el período comprendido entre julio de 2011 y febrero de 2012. El universo estuvo constituido por 84 niños de seis a doce años y la muestra por 67 escolares. La fluorosis dental se clasificó en: leve, moderada y grave. Las concentraciones de flúor natural en el agua de consumo, la exposición a altas concentraciones del elemento y el tiempo de exposición al mismo, fueron los factores de riesgo asociados a la fluorosis dental estudiados. Al concluir el estudio, se observó un predominio de la fluorosis dental leve (52,9 %, seguido de la moderada (38,2 %. Las concentraciones de flúor natural encontradas en las aguas de consumo fueron óptimas (0,7 y 1,2 ppm en el 44,8 % de los casos y altas (1,7 y 2,0 ppm en el 55,2 %. El 81,8 % de los casos sin fluorosis han estado expuestos a la acción del flúor solamente de uno a tres años, mientras que todos los niños con fluorosis dental lo han recibido por más de cuatro años, aumentando la severidad en la medida en que se incrementa el tiempo de exposición.

    Full Text Available An alternative technique for the production of dental restorations with porcelain, is the electrophoretic deposition (EPD. In this work, deposits of dental porcelain on stainless steel were obtained by EPD using water, ethanol and isopropanol as suspension mediums. The effect of the porcelain concentration, the intensity of the electric field and the suspension medium on the quantity of deposited mass were studied. All the tests were carried out at constant voltage, using a deposition time of 3 min. The particle size of the dental porcelain was in the range between 1.5 and 2.3 μm in the suspension. The results showed that the porcelain in the aqueous medium presented the major deposition velocity, in comparison with both ethanol and isopropanol. However, due to low the low suspension stability and hydrolysis of the water problems, the best coating finishes were obtained with ethanol. These results were obtained applying voltages between 70 and 150 V, for a deposition time of 3 min. Using isopropanol heterogeneous deposits were obtained due to the low suspension stability and to electrochemical reactions problems in the working electrodes, resulted from the high voltages application.

  18. La Stevia rebaudiana como coadyuvante en la prevención y el control de la caries dental: una revisión de literatura

    Directory of Open Access Journals (Sweden)

    Andrea Elena Paredes Vélez

    2016-07-01

    Full Text Available Introducción: La caries dental es la enfermedad crónica más prevalente en el mundo, y en Colombia, como en otros países, es considerada como un problema de salud pública. Es una enfermedad compleja, dinámica, y para su desarrollo intervienen muchos factores; la dieta rica en carbohidratos, es uno de los más significativos. La sacarosa se ha relacionado con problemas de salud como la caries, por ello, es deseable su reemplazo por edulcorantes con menos efectos adversos, y que aporten beneficios a la salud general y bucal de los humanos. Objetivo: fundamentar, si la Stevia, podría ser considerada como un coadyuvante en la prevención y control de la caries dental. Metodología: se realizó una búsqueda de literatura utilizando las bases de datos: Pubmed, Academic Search Complete, Embase, ScienceDirect, y el motor de búsqueda Google académico, mediante los términos MESH: “Dental Caries”, “Stevia”, “Anti-bacterial Agents”, “Sweetening Agents” y palabras clave en español: “Caries dental”, “Edulcorantes”, “Stevia”. Resultados: Los estudios revisados in vivo e in vitro mostraron: actividad antibacteriana de extractos de Stevia sobre microorganismos relacionados con caries dental, bajo potencial acidogénico y disminución en la formación de biopelícula dental, debido a la disminución de la hidrofobicidad celular e inhibición de la síntesis de polisacáridos extracelulares. Conclusiones: Aunque la evidencia científica aún es insuficiente, la Stevia rebaudiana es una adecuada candidata a reemplazar la sacarosa y puede considerarse como coadyuvante potencial para disminuir los niveles de caries dental, sin embargo, se recomienda realizar más estudios controlados y aleatorizados para que dicho rol se confirme.

    Full Text Available Objetivo: Establecer la prevalencia de caries dental y su manejo terapéutico tradicional en la población indígena wayuu de la Guajira colombiana. Materiales y métodos: Se realizó un examen oral a 245 niños en edad escolar que asisten a la concentración escolar Camino Verde del Municipio de Manaure en la Guajira Colombiana; mediante entrevistas semiestructuradas con la población, se hizo reconocimiento de las plantas que son utilizadas para tratar los problemas de salud oral. Se analizo e interpretó el concepto de la salud bucal, en una comunidad que resalta la importancia del equilibrio con la naturaleza; los recursos que utilizan para preservar una adecuada higiene oral, la interacción de la naturaleza con su cuerpo para mantener un equilibrio con la vida. Resultados: Los indices Ceo-d y CPO-D en comparacion con el estudio del ENSAB III, mostraron un aumento de la prevalencia de caries; solo los niños de 5 años presentan  un promedio de caries mas bajo en comparacion con los resultados de este estudio. De otra parte, el tratamiento y prevencion de las patologias de cavidad oral siguen siendo tratadas bajo la medicina tradicional indigena, aunque la medicina occidental ya hace parte de la terapeutica de la poblacion. Conclusiones: Los resultados sugieren trabajar mas en la promocion de la salud oral, para asi bajar los indices de caries; Por otro lado, La medicina tradicional indigena aunque importante, no refleja sus efectos, ademas de observar que la medicina occidental ha tenido gran acogida y cada vez su uso es mayor.

    Full Text Available Se describen los resultados de una investigación desarollada sobre una muestra de 1.115 preescolares (5 años de jardines de infantes de la Ciudad de Córdoba (Argentina, destinada a establecer la prevalencia y distribución de la caries dental conforme a su nivel económicosocial. El estudio reveló que, respecto a 1973, la prevalencia de caries disminuyó el 55,0%, en tanto que la proporción de niños con dientes sanos fue mayor en el 26,7%. La frecuencia y severidad de la caries aumentó a medida que descendía la ubicación social del niño. En el nivel económicosocial más alto (NES I = burguesías empresarial y gerencial, los índices de caries fueron significativamente menores que en el nivel económicosocial más bajo (NES III = proletariado típico, proletariado no típico y subproletariado: ceo-d de 0,8 y 2,7 y ceo-s de 0,9 y 4,9, respectivamente. En el NES III, los principales componentes del ceo-d fueron dientes cariados y con extracción indicada, mientras que en el NES I fueron los dientes obturados. La proporción de niños sin experiencia de caries fue del 63,1% en el NES I y del 11,5% en el NES III. Inversamente, el índice de salud bucal resultó más alto en el NES I (8,8 que en el NES III (5,1. El gasto demandado por niño para el tratamiento restaurativo es aproximadamente dos veces y media más alto en el NES III que en el NES I. Considerando toda la muestra, el gasto en el NES III resultaría más de diez veces superior al del NES I. Se concluye que la programación de la atención odontológica privilegiando a los niños del NES III, que son los de mayor riesgo de enfermar, puede contribuir a contrarrestar los desniveles en el estado de salud bucal.

    Full Text Available El Índice de Estética Dental, DAI, permite determinar la severidad de las maloclusiones, con lo que se puede priorizar la necesidad de tratamiento ortodóncico de los pacientes. Material y Métodos: la muestra fue de 123 modelos de estudio pretratamiento de ortodoncia, se valoraron los modelos de estudio con el Índice de Estética Dental, se tabuló y calculó la estadística descriptiva con programa Microsoft Office Excel 2007. Resultados: El promedio del DAI fue de 39.84, el 53% de la población presentó una maloclusión muy severa con necesidad de tratamiento obligatorio, el 17.9% con maloclusión severa con necesidad de tratamiento deseable por el paciente, la categoría de maloclusión definitiva, que requiere tratamiento, se presentó en el 17.1% y solo el 11.4% presentó una oclusión normal sin necesidad de tratamiento. Conclusión: En la población de estudio fue mayor el porcentaje de maloclusión muy severa, las otras tres categorías del índice presentaron valores del 17% al 11%. Las mujeres que acudieron a atención con el ortodoncista presentaron mayor porcentaje de severidad de maloclusión que los hombres. Estos porcentajes demuestran que los pacientes que acuden, o son remitidos al ortodoncista, presentan maloclusiones severas.

    Full Text Available Introducción: Las resinas dentales basadas en siloranos, son el resultado de la unión química de siloxanos y oxiranos. Dentro del proceso de evolución de las resinas, se han modificado sus formulaciones para optimizar sus propiedades físicas, mecánicas y estéticas. Sin embargo, aún presentan problemas como la contracción de polimerización, problemas alérgicos y toxicológicos. Objetivo: Determinar el potencial efecto citotóxico de las resinas a base de siloranos sobre la viabilidad celular en un cultivo de fibroblastos de la línea L929. Metodología: Se estudió la exposición de fibroblastos de ratón L929 a resinas dentales a base de siloranos Filtek p90 y metacrilatos Filtek p60 en tres tiempos de fotocurado durante 6 días. Se evaluó el efecto sobre la viabilidad celular mediante pruebas de exclusión vital, micrografías electrónicas y composición elemental de superficie (Mg, Na, K y Ca por ESEM/EDAX. Resultados: La resina Filtek p90 mostró un mayor efecto citotóxico a tiempos de fotocurado prolongados (20 segundos o más respecto a la resina Filtek p60. El efecto resultó más marcado para 20 segundos de fotocurado, ya que las concentraciones de Ca y K en la superficie celular fueron las más afectadas. Conclusiones: La resina dental Filtek p90 ejerce un efecto citotóxico relativamente bajo sobre las células de fibroblastos L929 (p <0.01. Su uso en la práctica odontológica se puede considerar bioseguro, pero un tiempo de fotocurado prolongado con la resina dental a base de siloranos puede afectar significativamente la viabilidad de los tejidos dentales

    Cummins, D

    2013-10-22

    este artículo discute brevemente la prevalencia de caries, la naturaleza multifactorial de su etiología, el riesgo de caries y el papel y eficacia del fluoruro. Resalta también la investigación sobre el metabolismo bacteriano, que ha aportado conocimientos sobre la defensa natural oral contra la caries y la base para el desarrollo de una nueva tecnología para la prevención diaria y el tratamiento de la caries. Por último, se resume la evidencia que respalda que la tecnología complementa y mejora la eficacia anti-caries de la crema dental con fluoruro. los datos globales muestran que a pesar de la exitosa introducción del fluoruro, la caries dental es una enfermedad prevalente. La experiencia de caries depende del balance entre el consumo de azúcares, la higiene oral y el uso del fluoruro. Hay tres conceptos científicos que son fundamentales en las nuevas mediciones para detectar, tratar y monitorear la caries: (1) la caries dental es un proceso dinámico, (2) la caries dental es un proceso continuo de etapas que van desde reversible (pre-clínica) hasta irreversible (lesiones clínicamente detectables), y (3) el proceso de la caries es un balance de factores patológicos y protectores que pueden modularse para el manejo de la caries. El fluoruro funciona como factor protector al detener y revertir el proceso de la caries, pero el fluoruro no previene los factores patológicos que inician el proceso. Se ha identificado una tecnología novedosa, basada en arginina y un compuesto insoluble de calcio, que está dirigida a la placa dental para prevenir la iniciación del proceso de caries al reducir los factores patológicos. Como los mecanismos de acción de la arginina y el fluoruro son altamente complementarios, se ha desarrollado un nuevo dentífrico que combina la arginina y el fluoruro, y se ha probado clínicamente que brinda una prevención superior contra la caries.

    Science.gov (United States)

    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.

  18. Dental caries

    Pitts, Nigel B; Zero, Domenick T; Marsh, Phil D

    2017-01-01

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

  19. Dental Calculus Arrest of Dental Caries.

    Keyes, Paul H; Rams, Thomas E

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

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

    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.

    Dental radiography must comply with the same regulations with which conventional radiography complies. Radiation doses to individual patients are low but, because of the large number of patients X-rayed, the collective dose to the population is not negligible. Care in siting and regular maintenance of the equipment will reduce doses to both staff and patients. To produce X-ray films with a good image quality using a low radiation dose requires attention to film processing; this is often a neglected area. (Author)

    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.

Environmental risk factors associated with tooth decay in children: a review of four studies in Indonesia Riesgos ambientales asociados con la caries dental en niños: una revisión de cuatro estudios en Indonesia Fatores de risco ambientais associados à cárie dentária nas crianças: uma revisão de quatro estudos na Indonésia

    2013-06-01

    Full Text Available There is growing concern over studying the environmental impacts on human health. Among the world’s population, children are particularly vulnerable to environmental threats.Currently, in certain areas of Indonesia, there are significant problems with water quality, especially as many consume surface water for drinking. There is evidence that this contributes to tooth decay – the process of dental caries. Furthermore, teeth provide an excellent chronological record of nutritional status and trace metal exposure during human development.This paper provides an overview of risk factors for dental caries and reviews four epidemiological and laboratory studies that have addressed these issues in Indonesia. First, Winanto in 1993 showed that acidity and high tin (Sn concentrations in drinking water are associated with the erosion of permanent teeth in children living close to a tin mining area. Second, Wulandari in 2009, using Graphite Furnace Atomic Absorption Spectrometry (GFAAS, showed that deciduous teeth containing high concentration of lead (Pb have 3 times higher risks of contracting caries. Third, Satrio in 2010 compared the dental status of children who consumed rain water with those using other sources of drinking water: this revealed that low concentration of Fluoride in drinking water contributes 19 times higher risk of dental caries and low pH 22 times the risk compared to water of neutral pH. Fourth, Musadad in 2009 undertook an ecological study on the effect of drinking water quality in relation to dental caries and revealed significant associations with acidity, total water consumption, household expenditure and the distance from a subject’s residence to the nearest dental health provider.Thus, in Indonesia, tooth decay is not only associated with poor diet and poor oral hygiene; it also reflects poor environment.Existe una creciente preocupación por el estudio de los impactos ambientales en la salud humana.

    The High Dynamic Range Visible Difference Predictor (HDR-VDP) was created to overcome the poor correlation between objective and subjective digital image quality criteria. This metric has been successfully tested to analyze the effect of medical images compression over image quality. A study using 13 dental panoramic images of an anthropomorphic phantom was carried out. Images were acquired with a digital Kodak equipment. Tube current and beam energy were changed among studies in order to analyze how the image quality was affected by the acquisition parameters variation. The criterion about image quality of two expert observers was taken into account. Furthermore, HDR-VDP was fitted to the problem under analysis. Correlation between the metric and the subjective criterion was also analyzed. HDR-VDP had a correlation of r 0.683 (p = 0. 013) with respect to the subjective criterion. The metric calculated over 9 x 9 pixel windows in regions of interest was able to detect differences in image quality for a typical range of kVp and mA in this type of study. (Author) 17 refs.

    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 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

    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.

    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.)

    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.

  14. What is dental ecology?

    Science.gov (United States)

    Cuozzo, Frank P; Sauther, Michelle L

    2012-06-01

    Teeth have long been used as indicators of primate ecology. Early work focused on the links between dental morphology, diet, and behavior, with more recent years emphasizing dental wear, microstructure, development, and biogeochemistry, to understand primate ecology. Our study of Lemur catta at the Beza Mahafaly Special Reserve, Madagascar, has revealed an unusual pattern of severe tooth wear and frequent tooth loss, primarily the result of consuming a fallback food for which these primates are not dentally adapted. Interpreting these data was only possible by combining our areas of expertise (dental anatomy [FC] and primate ecology [MS]). By integrating theoretical, methodological, and applied aspects of both areas of research, we adopted the term "dental ecology"-defined as the broad study of how teeth respond to the environment. Specifically, we view dental ecology as an interpretive framework using teeth as a vehicle for understanding an organism's ecology, which builds upon earlier work, but creates a new synthesis of anatomy and ecology that is only possible with detailed knowledge of living primates. This framework includes (1) identifying patterns of dental pathology and tooth use-wear, within the context of feeding ecology, behavior, habitat variation, and anthropogenic change, (2) assessing ways in which dental development and biogeochemical signals can reflect habitat, environmental change and/or stress, and (3) how dental microstructure and macro-morphology are adapted to, and reflect feeding ecology. Here we define dental ecology, provide a short summary of the development of this perspective, and place our new work into this context. Copyright © 2012 Wiley Periodicals, Inc.

    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.

    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.

    Modern dentistry can not exist without dental implantation. This work is devoted to study of the "bone-implant" system and to optimization of dental prostheses installation. Modern non-invasive methods such as MRI an 3D-scanning as well as numerical calculations and 3D-prototyping allow to optimize all of stages of dental prosthetics. An integrated approach to the planning of implant surgery can significantly reduce the risk of complications in the first few days after treatment, and throughout the period of operation of the prosthesis.

  3. Economic impact of dental hygienists on solo dental practices.

    Lazar, Vickie F; Guay, Albert H; Beazoglou, Tryfon J

    2012-08-01

    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.

    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.

    The number of dental radiographs taken in the UK has steadily increased over the past 20 years--recently estimating around 18 million taken in the general dental services alone, and dental radiographs now account for nearly 25% of all medical radiographic exposures. Radiographs remain our most useful diagnostic aid. Their strength is in demonstrating hard tissue pathology, which makes radiographs particularly effective in the maxillofacial region. Although well accepted in this capacity, there remain a number of limitations and drawbacks to conventional radiographs which recent developments have begun to overcome. There have been improvements in the scope and capabilities of dental imaging equipment. There has also been a continuing effort to reduce radiation-induced harm by limiting our exposure to it. This has been possible both through the introduction of new methods and protocols for reducing individual radiation exposures and by the creation of guidelines for selecting radiographs more effectively and thereby reducing the total number of radiographs taken.

    Apparatus is described for improving the handling rate of patients in panoramic dental radiography when tube head-camera assembly of a low silhouette panoramic dental X-ray machine is rotated for a scan in one direction only. This is effected by fast return of the tube head-camera assembly with its simultaneous elevation, thus facilitating the radiographed patient's exit from the machine and the entrance of another patient. Fast speed is about twice the scanning speed. (author)

  15. Saliva and dental erosion

    2012-10-01

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

    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.

  18. Traumatismo dental en bebés

    Full Text Available Las ocurrencias traumáticas pueden traer consecuencias desagradables tanto en lo físico como en lo estético, como en el aspecto psicológico. Los traumas sufridos por bebés traen situaciones casi irreparables en el momento, tales como las limitaciones inherentes a la edad del paciente cuando aún es bebé. Las soluciones protésicas, por ejemplo, son casi siempre descartadas porque la edad del paciente es incompatible con el uso de una prótesis. Así, como ésta, también ocurren muchas otras situaciones, limitando un tratamiento inmediato y representando para el paciente un problema a ser resuelto. Por lo tanto, en el trabajo se hace una revisión de la bibliografía que aborda el traumatismo dental en bebés y comentarios sobre los exámenes a realizar, siempre considerando la edad, crecimiento y desarrollo, además de relatar las consecuencias de esos traumatismos en esta franja etaria inicial de vida como resultado. Finalmente, trata de alertar a los responsables de los niños de los cuidados de emergencia que se deben tener en algunas ocurrencias de traumatismos dentales en bebés.

    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%.

  7. 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.

    Since the invention and the discovery of x-rays, physicians, surgeons and life scientists have been using images to diagnose and subsequently treat diseases. X-ray is also widely used in many imaging techniques to better understand basics anatomy, physiology and biology as well as testing and analytical work in physical science. In dentistry, x-ray technique has been employed to get a panoramic view of the whole teeth of a particular patient. A panoramic dental radiograph is very useful in dentistry for diagnostic purpose, denture preparation, as well as for orthodontic. Image visualisation is an important aspect especially for the dentists to analyse and proceed with a particulate dental treatment. In this project panoramic dental image obtained by using a standard phantom is visualised by using Interactive Data Language (IDL) software. A panoramic dental x-ray machine, Cranex3, is used to get a panoramic radiograph, which is subsequently digitized, by using Vidar digitizer (Sierra Plus). The 2D digitized image is enhance and apply other visualising techniques such as surface rendering and volume rendering technique using Interactive Data Language (IDL) software as a first step in 3D visualisation. In this paper, visualising of panoramic dental radiograph by using IDL is discussed in brief. (Author)

    Full Text Available Se determinó la seroprevalencia de leptospirosis en una población canina suburbana con el objeto de analizar la asociación entre distintas variables individuales y ambientales y la seropositividad a leptospirosis. El estudio, de diseño transversal, se llevó a cabo durante julio de 1992 en un barrio del Gran Buenos Aires en el que viven unos 9 500 habitantes y una población canina de unos 2 000 animales. Se estudió una muestra aleatoria de 223 perros, de cada uno de los cuales se obtuvo una muestra de sangre. La ficha epidemiológica del animal se obtuvo por encuesta al ama de casa. Las determinaciones serológicas se realizaron por microaglutinación frente a 10 serotipos de Leptospira interrogans. Se halló seropositividad en 57% de los 223 perros examinados; 82% de los sueros positivos coaglutinaron con dos o más serotipos. Los serotipos detectados con mayor frecuencia fueron canicola y pyrogenes. La seroprevalencia en hembras fue menor que en machos (P <0,05 y entre los cachorros de menos de 1 año de edad, menor que en los animales de mayor edad (P <0,01. El callejeo del perro y la presencia de agua estancada frente a la vivienda del propietario fueron los factores de riesgo más importantes entre los que se estudiaron. Las asociaciones de la seropositividad con el contacto con un basural, con el comportamiento de caza del perro y con la presencia de roedores en la vivienda no fueron estadísticamente significativas. Se discuten distintas medidas de control.

    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

    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.

The study used an anaglyph technique in which two images were presented separately to the left and right eyes (using red/cyan filters), which, combined in the brain, give enhanced depth...... perception. A positional judgment task was performed to assess whether the use of stereoscopy would enhance depth perception among dental students at Osaka University in Japan. Subsequently, the optimum angle was evaluated to obtain maximum ability to discriminate among complex anatomical structures. Finally...... practice, they did recognize its merits for education. These results suggest that using stereoscopic images in dental education can be quite valuable as stereoscopy greatly helped these students' understanding of the spatial relationships in complex anatomical structures....

    The objective of this research is to demonstrate the risks and consequences of exposure to dental X-ray. The methodology used was the survey of bibliographic literature on this matter. First, we tried to understand the operation and characteristics of dental X-rays. Afterwards, we tried to know about the risks that this procedure offers to workers and patients. And concluded with the consequences of such exposure. The results showed that dental x-rays only offer risks in prolonged exposure, can affect the worker or patient to pathologies such as cancer or a life-time decreased due to the stochastic effect. Therefore, radiological protection standards must be respected and practised. (author)

    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.

    Full Text Available Background. In 1999, An Oral Health Survey of American Indian and Alaska Native (AI/AN Dental Patients found that 79% of 2- to 5-year-olds had a history of tooth decay. The Alaska Native Tribal Health Consortium in collaboration with Alaska’s Tribal Health Organizations (THO developed a new and diverse dental workforce model to address AI/AN oral health disparities. Objectives. This paper describes the workforce model and some experience to date of the Dental Health Aide (DHA Initiative that was introduced under the federally sanctioned Community Health Aide Program in Alaska. These new dental team members work with THO dentists and hygienists to provide education, prevention and basic restorative services in a culturally appropriate manner. Results.

    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.

    Zhang, Yu; Sailer, Irena; Lawn, Brian R

    2013-12-01

    Clinical data on survival rates reveal that all-ceramic dental prostheses are susceptible to fracture from repetitive occlusal loading. The objective of this review is to examine the underlying mechanisms of fatigue in current and future dental ceramics. The nature of various fatigue modes is elucidated using fracture test data on ceramic layer specimens from the dental and biomechanics literature. Failure modes can change over a lifetime, depending on restoration geometry, loading conditions and material properties. Modes that operate in single-cycle loading may be dominated by alternative modes in multi-cycle loading. While post-mortem examination of failed prostheses can determine the sources of certain fractures, the evolution of these fractures en route to failure remains poorly understood. Whereas it is commonly held that loss of load-bearing capacity of dental ceramics in repetitive loading is attributable to chemically assisted 'slow crack growth' in the presence of water, we demonstrate the existence of more deleterious fatigue mechanisms, mechanical rather than chemical in nature. Neglecting to account for mechanical fatigue can lead to gross overestimates in predicted survival rates. Strategies for prolonging the clinical lifetimes of ceramic restorations are proposed based on a crack-containment philosophy. Copyright © 2013 Elsevier Ltd. All rights reserved.

    2009-12-01

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

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

    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 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.

    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.

    Full Text Available En 1979, tras una década de dictaduras militares, se inició la fase constitucional más larga en la historia del Ecuador. Ésta se levantó sobre las herencias del pasado y se caracterizó, de manera fundamental, por el tránsito desde un modelo estatal-desarrollista hacia uno de tipo empresarial, por el aparecimiento de nuevos agentes sociales, el multipartidismo político, la regionalización nacional, la presencia multicultural y la inserción del país en nuevas relaciones internacionales. Pero esos procesos trajeron como consecuencias centrales: la edificación de una economía inequitativa, una sociedad tensionada, la desestructuración institucional, la precarización del trabajo y la debilidad con la que la nación ha enfrentado el nuevo mundo unipolar. Todo ello ha configurado un cuadro de riesgos para la incipiente democracia. El Ecuador contemporáneo tiene, por tanto, una serie de desafíos económicos, sociales y políticos para escapar a la inestabilidad que ha acompañado a la construcción de su modernización democrática.___________________ABSTRACT:In 1979, after one decade of military dictatorships, the longest constitutional phase in the history of Ecuador was initiated.

    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.

    2010-03-01

    Full Text Available La osteointegración es la conexión estructural y funcional entre el hueso y un implante. Cuando un implante se inserta en el hueso, se crea la denominada interfase hueso-implante, una zona de unión entre la superficie del biomaterial del implante y el hueso circundante. La cicatrización de esta interfase depende de las condiciones biológicas del hueso, las características de diseño del implante y la distribución de cargas entre hueso e implante. En este artículo se hace una revisión del proceso de cicatrización de la interfase hueso-implante para el caso de un implante dental. El objetivo es describir la secuencia de eventos biológicos iniciados con la lesión causada por la inserción del implante y que concluyen con la formación de nuevo hueso en la interfase. Esta descripción incluye una novedosa clasificación de los fenómenos mecánicos que intervienen durante el proceso de cicatrización de los tejidos lesionados. Esta descripción mecanobiológica de la interfase hueso-implante dental se utiliza para determinar las características más relevantes a tener en cuenta en la formulación de un modelo matemático de la osteointegración de implantes dentales.The osteointegration is the structural and functional connection between bone and implant. When an implant is inserted in bone, it creates the so-called bone-implant interphase, a joint zone between implant biomaterial surface and the surrounding bone.

The objective was to identify whether the dental students followed the principles of ergonomics during clinical visits, evaluating, through photographs, compliance with ergonomic principles applied in dental practice, and finally identify the most affected sites by RSI / WMSDs of students enrolled in the dental clinic of the Faculdade IMED. Snapshots were made and only considered the position of the student operator, the same taken by the researcher using the mobile device. For each clinical procedure were taken two photographs in hidden angles to the student operator so that it did not change its ergonomic position to be observed. After obtaining the photos, they were evaluated and classified in scores from 0 to 3 according to the adequacy of the work placement, and then inserted into Excel and later in a database (SPSS 15.0. The following work is a cross-sectional, observational study, they were conducted in dental clinics IMED college. Among the 66 respondents, 14 were male and 52 female. It was found that 57 (86,3% reported feeling pain somewhere in the body, being the most affected sites neck (36.4%, and consecutively lower back (30.3% and higher than the back (27.3%. The results of the 63 procedures performed by the photographic shots were classified as “inadequate” in 49 procedures, “partially adequate” in 12 and “impossible to evaluate” in 2 procedures. The research results have shown a high prevalence of musculoskeletal pain and do not follow the ergonomic principles, emphasizing the need for more attention to ergonomics of the students.

    A checklist for verification of unethical business practices, originally formulated by Drs. Blanchard and Peale, is adapted to dental practice. A scenario is used as a model to demonstrate the applicability of this instrument to dental practice. The instrument asks three questions in regards to an ethical dilemma: 1) Is it legal? 2) Is it fair? 3) How does it make you feel? The paper concludes the giving of gifts to general dentists by dental specialists for the referral of patients is unethical.

  16. Confronting shibboleths of dental education.

    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.

    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.

    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.

    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

    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.

    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.

  2. Competition and dental services.

    Grytten, J; Sørensen, R

    2000-07-01

    Dental services for adults are different from all other Norwegian health services in that they are provided by private producers (dentists) who have full freedom to establish a practice. They have had this freedom since the end of World War II. A further liberalization of the market for dental services occurred in November 1995, when the so-called normal tariff was repealed. The system changed from a fixed fee system to a deregulated fee system. In principle, the market for dental services for adults operates as a free competitive market, in which dentists must compete for a market share. The aim of this study was to study the short-term effects of competition. A comprehensive set of data on fees, practice characteristics, treatment profiles and factors that dentists take into account when determining fees was analysed. The main finding was that competition has a weak effect. No support was found for the theory that the level of fees is the result of monopolistic competition or monopoly. The results also provided some evidence against the inducement hypothesis. At this stage, it is interesting to notice that dentists do not seem to exploit the power they have to control the market. One explanation, which is consistent with the more recent literature, is that physicians' behaviour to a large extent is influenced by professional norms and caring concerns about their patients. Financial incentives are important, but these incentives are constrained by norms other than self-interest. The interpretation of the results should also take into account that the deregulation has operated for a short time and that dentists and patients may not yet have adjusted to changes in the characteristics of the market.

    2013-01-01

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

    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.

    Full Text Available This article focuses on the women’s magazine Ellas, published in the mid-nineteenth century in Madrid, and discusses its relationship with other approximately contemporary magazines and newspapers in order to contribute to a reconstruction of the history of women’s publications in the Spanish press. The approach is based on an analysis of the text of each issue of the magazine and comparison with other publications, where applicable. Key features of the article include a reflection on the social rights of women, an attempt to analyse the main differences between women and men and defining features of sexual gender, the need for women’s education, etc. Studying the magazine’s content clearly reveals a continual tension between progressive and conservative ideas typical of the historical context in which gender studies emerged in Spain.Este artículo centra su atención en la revista para mujeres Ellas, publicada a mediados del siglo XIX en Madrid. Analiza, asimismo, la relación de esta publicación con algunas otras revistas y periódicos de su contexto histórico próximo, con el fin de contribuir a la reconstrucción de una Historia de las publicaciones para mujeres en la prensa española. Para ello se utiliza el análisis de textos que forman parte de los números que componen la revista, así como el análisis comparativo entre publicaciones, cuando es pertinente. Entre los aspectos de mayor interés que el artículo pone de relieve se encuentra la reflexión sobre los derechos sociales de las mujeres, el intento de análisis de las principales diferencias entre mujeres y hombres y de los rasgos definitorios de los géneros sexuales, la necesidad de educación de las mujeres, entre otros. El estudio del contenido de la publicación revela claramente una tensión contradictoria continua entre las ideas progresistas y las ideas conservadoras propias del momento histórico que dieron origen en España al nacimiento de los estudios de género.

    The American Dental Dream-the cultural desire for straight, white teeth-is difficult, if not impossible, for poor and working-class people to achieve. Using ethnographic fiction, autoethnography, poetry, and qualitative interviewing, I brush away the taken-for-granted assumptions about teeth. I explore the personal, relational, and structural consequences of this cultural desire, and show how social class writes itself on our bodies. I write these culture-centered teeth tales to show how one might cope with their teeth.

  8. Adhesive dental materials

    2005-01-01

    Two main classes of material are involved, the glass-ionomer cements and the composite resins. This investigation describes the way they are bonded to the tooth and highlights their differences. Glass ionomers develop a zone of interaction with the tooth as they age which ultimately gives an extremely strong bond, and results in excellent retention rates. By contrast, bonding of composite resins is more complicated and possibly less effective, though these materials have better wear resistance and better aesthetics than glass ionomers. Assessment of bond durability is difficult. This is because a dental restorative can fail by a number of mechanisms apart from de bonding: for example, through wear or fracture

  10. Gnomon una indagine sul numero

    CERN Document Server

    Zellini, Paolo

    1999-01-01

    Lo "gnomone" di cui si parla in questo libro non è quello stilo, più o meno monumentale, la cui ombra indica l'ora solare, ma un semplice strumento matematico: una figura geometrica, piana o solida, che aggiunta a un'altra ne genera una simile. Si tratta quindi di una tecnica, ampiamente diffusa nell'antichità, atta a ingrandire o rimpicciolire una forma conservandone l'aspetto. Lo gnomone non aveva solo importanza geometrica. Dalla semplice operazione di correzione "gnomonica" di una figura sono dipesi infatti la stessa nozione di numero, la definizione di vari concetti dell'Analisi e alcuni tra i principali algoritmi numerici e algebrici della matematica.

    2007-06-01

    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.

    1989-10-01

    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

  3. Cones for dental radiography

    Energy Technology Data Exchange (ETDEWEB)

    Butler, M J [National Radiological Protection Board, Harwell (UK)

    1977-04-01

    Dental radiographic techniques are summarized. The advantages and disadvantages of the use of both the conventional plastic pointer cone and the open-ended cylinders or divergent cones favoured both by the ICRP (Protection against Ionizing Radiation from External Sources, Oxford, Pergamon Press, 1973, ICRP Publication 15), and in the Code of Practice for the Protection of Persons against Ionizing Radiation arising from Medical and Dental Use (1972, 3rd edition, London, HMSO) are discussed. The use of the word 'should' in these recommendations to signify a desirable requirement, not an essential one, is noted. This wording is currently of interest both nationally and internationally in relation to regulations, standards and notes for guidance. The National Radiological Protection Board (NRPB) has been reviewing the position, and has concluded that open-ended cones have disadvantages which may sometimes outweigh their advantages. Although open-ended cones are preferable under some circumstances, the recommendation that they should be used ought not to be followed without an understanding of the issues involved. The hazards associated with the use of interchangeable cones are considered. The NRPB now proposes that the requirement for the replacement of pointer cones (for both new and existing equipment) should be withdrawn.

    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

  6. 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.

    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

    Full Text Available The replacement of teeth by implants is usually restricted to patients with completed craniofacial growth. The aim of this literature review is to discuss the use of dental implants in normal growing patients and in patients with ectodermal dysplasia and the influence of maxillary and mandibular skeletal and dental growth on the stability of those implants. It is recommended that while deciding the optimal individual time point of implant insertion, the status of skeletal growth, the degree of hypodontia, and extension of related psychological stress should be taken into account, in addition to the status of existing dentition and dental compliance of a pediatric patient.

    Dental public health has been defined as 'the science and art of preventing oral diseases, promoting oral health and improving the quality of life through the organised efforts of society'. Dental practitioners most often have the oral health of individual patients as their primary focus but the aim of public health is to benefit populations. Early developments in dental public health were concerned largely with demonstrating levels of disease and with treatment services. With greater appreciation of the nature of oral health and disease, and of their determinants has come recognition of the need for wider public health action if the effects of prevention and oral health promotion are to be maximized.

    Huang, M; Wang, R; Thompson, V; Rekow, D; Soboyejo, W O

    2007-01-01

    This paper considers the use of bioinspired functionally graded structures in the design of dental multi-layers that are more resistant to sub-surface crack nucleation. Unlike existing dental crown restorations that give rise to high stress concentration, the functionally graded layers (between crown materials and the joins that attach them to dentin) are shown to promote significant reductions in stress and improvements in the critical crack size. Special inspiration is drawn from the low stress concentrations associated with the graded distributions in the dentin-enamel-junction (DEJ). The implications of such functionally graded structures are also discussed for the design of dental restorations.

    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.

    To discover the quality of written instructions from dentists to dental technicians and the nature of non-compliant prescriptions. An audit of laboratory prescription compliance was conducted within an NHS Trust Dental Teaching Hospital to determine the level of communication between dentists and dental technicians. One hundred and fifty prescriptions were audited from dental undergraduates and qualified dentists throughout the different departments. A total of two-thirds of prescriptions were considered non-compliant and failed to meet relevant ethical and legal guidelines. This problem was seen throughout all departments and at all professional levels. A breakdown in communication between dentists and technicians through the use of prescriptions is evident even within a close working environment.

    2015-01-01

    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...

    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

  1. Dental responsibility loadings and the relative value of dental services.

    Teusner, D N; Ju, X; Brennan, D S

    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.

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

    Computerised tomography (CT) plays a key role in the pre-surgical evaluation of the alveolar process for titanium dental implants. The successful replacement of lost teeth by tissue integrated tooth root implants is a major advance in clinical dentistry. The paper will discuss briefly the history of osseointegration and how CT is now involved in helping the edentulous patient. CT is considered as a quick and convenient method of obtaining excellent anatomical information about the maxilla. Conventional tomography is difficult to obtain and does not provide valuable cross-sectional images. Exact height and width calculations can be made as well as screening out patients with advanced bone resorption. 3 refs. 6 figs

    The recognition of periodontal diseases as amenable to local antibiotherapy has resulted in a paradigmatic shift in treatment modalities of dental afflictions. Moreover the presence of antimicrobial resistance, surfacing of untoward reactions owing to systemic consumption of antibiotics has further advocated the use of local delivery of physiologically active substances into the periodontal pocket. While antimicrobials polymerized into acrylic strips, incorporated into biodegradable collagen and hollow permeable cellulose acetate fibers, multiparticulate systems, bio-absorbable dental materials, biodegradable gels/ointments, injectables, mucoadhesive microcapsules and nanospheres will be more amenable for direct placement into the periodontal pockets the lozenges, buccoadhesive tablets, discs or gels could be effectively used to mitigate the overall gingival inflammation. Whilst effecting controlled local delivery of a few milligram of an antibacterial agent within the gingival crevicular fluid for a longer period of time, maintaining therapeutic concentrations such delivery devices will circumvent all adverse effects to non- oral sites. Since the pioneering efforts of Goodson and Lindhe in 1989, delivery at gingival and subgingival sites has witnessed a considerable progress. The interest in locally active systems is evident from the patents being filed and granted. The present article shall dwell in reviewing the recent approaches being proffered in the field. Patents as by Shefer, et al. US patent, 6589562 dealing with multicomponent biodegradable bioadhesive controlled release system for oral care products, Lee, et al. 2001, US patent 6193994, encompassing a locally administrable, biodegradable and sustained-release pharmaceutical composition for periodontitis and process for preparation thereof and method of treating periodontal disease as suggested by Basara in 2004via US patent 6830757, shall be the types of intellectual property reviewed and presented in

    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.

  6. The Phenomenon of Dental Fear

    DEFF Research Database (Denmark)

    Moore, Rod

    Odontophobia is a rather unique phobia with special psychosomatic components that impact on the dental health of odontophobic persons. It also has psychosocial components largely as a result of destruction of the teeth and subsequent embarrassment that can affect a person and cause a vicious cycle...... of dental fear (see fig. 1). The phenomenon is facilitated by misunderstandings and myths generated by both patients and dentists (see table 1 for examples). The most common reasons given in the literature for such strong fears of dental treatment are: 1) bad experiences in childhood for 85% of cases, 2......) feeling of powerlessness and lack of control over personal emotional reactions and over the social situation in the dental chair, 3) social learning processes in which the image of the dentist is cast in a negative light by the mass media or by the person's relatives or friends and 4) that the person has...

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

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

    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.

    Dental fluorosis occurs as a result of excess fluoride ingestion during tooth formation. Enamel fluorosis and primary dentin fluorosis can only occur when teeth are forming, and therefore fluoride exposure (as it relates to dental fluorosis) occurs during childhood. In the permanent dentition, this would begin with the lower incisors, which complete mineralization at approximately 2–3 years of age, and end after mineralization of the third molars.

    The 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.

  17. Surface texture measurement for dental wear applications

    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.

    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.

El objetivo de esta revisión fue comparar los resultados de la evidencia sobre la relación entre obesidad y caries dental en niños, por lo cual se realizó una búsqueda computarizada y sistemática utilizando el término "dental caries" combinado con "obesity", "overweight" y "underweight" en las bases de datos Medline, Embase, Pubmed y Ovid, arrojando 439 artículos, de estos se seleccionaron 15 artículos que cumplieron con los criterios de inclusión y superaron una evaluación de calidad metodológica. Los hallazgos fueron almacenados y organizados en una base de datos, se procesaron y analizaron estadísticamente teniendo en cuenta razones de disparidad y el coeficiente de correlación de Pearson reportados. Se presentó un prevalencia general de caries dental de 49,6 %, para los obesos fue de 52,5 % y para los no obesos de 46,8 %. No se encontró asociación entre caries y obesidad en 9 de 15 estudios. La evidencia consultada sugiere que no existe relación entre obesidad y caries dental en niños, pues la prevalencia de caries no mostró diferencias estadísticamente significantes entre niños obesos y no obesos.

    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.

    2013-02-01

    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.

Association was tested using descriptive, bivariate and multivariate linear regression analysis, with a 5% significance level. Dentistry undergraduates reported lower scores than psychology (p < 0.001 and mathematics undergraduates (p < 0.05 for all three dimensions of the DFS. Negative dental experiences in childhood was associated with dimensions of Avoidance (B = 2.70, p < 0.001, Physiological arousal (B = 1.42, p < 0.001 and Fears of specific stimuli/situations (B = 3.44, p < 0.001. The reason for first visit to dentist was associated with dimensions of Physiological arousal (B = 0.76, p < 0.01 and Fears of specific stimuli/situations (B = 1.29, p < 0.01. Dentists should be encouraged to evaluate the dental fear of their patients before treatment. The DFS has been found to be an effective instrument for this purpose.

    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

    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?

    The central idea of the Brazilian health system is to prevent the establishment of disease or detect it as early as possible. Prevention and treatment of dental caries are related to behavioral factors, including dietary and oral hygiene habits, which are related to many chronic diseases. Dental health promotion therefore should be fully integrated into broadly based health-promoting strategies and actions such as food and health policies, and general hygiene (including oral hygiene), among others. For decades, a linear relationship between sugar consumption and caries has been observed. Recent data has indicated that this relationship is not as strong as it used to be before the widespread use of fluoride. However, diet is still a key factor acting in the carious process. Oral hygiene is a major aspect when it comes to caries, since dental biofilm is its etiological factor. Oral hygiene procedures are effective in controlling dental caries, especially if plaque removal is performed adequately and associated with fluoride. An alternative to a more efficient biofilm control in occlusal areas is the use of dental sealants, which are only indicated for caries-active individuals. If a cavity is formed as a consequence of the metabolic activity of the biofilm, a restorative material or a sealant can be placed to block access of the biofilm to the oral environment in order to prevent caries progress. The prevention of dental caries based on common risk-factor strategies (diet and hygiene) should be supplemented by more disease-specific policies such as rational use of fluoride, and evidence-based dental health care.

    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.

Only articles related to anodized implants were included. Both animal and human studies were included. Results: The initial search of articles resulted in 581 articles on anodized implants. The initial screening of titles and abstracts resulted in 112 full-text papers; 40 animal studies, 16 studies on cell adhesion and bacterial adhesion onto anodized surfaced implants, and 47 human studies were included. Nine studies, which do not fulfill the inclusion criteria, were excluded. Conclusions: The long-term studies on anodized surface implants do favor the surface, but in most of the studies, anodized surface is compared with that of machined surface, but not with other surfaces commercially available. Anodized surface in terms of clinical success rate in cases of compromised bone and immediately extracted sockets has shown favorable success.

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

  4. Hipodoncia y hueso navicular accesorio: una interesante asociación sindrómica

    Directory of Open Access Journals (Sweden)

    Mario Cantín

    2012-09-01

    Full Text Available Los dientes se desarrollan a partir de múltiples interacciones recíprocas entre células del epitelio oral y el ectomesénquima. Una serie de genes participan en el desarrollo del diente, así como de otros órganos y miembros superiores e inferiores. PAX9, miembro de la familia de factores de transcripción, es uno de los principales responsables de este desarrollo, y juega un rol fundamental en la hipodoncia dental y malformaciones en los huesos del miembro inferior. El objetivo de este reporte es presentar un caso de asociación entre hipodoncia y el hueso navicular accesorio. Se trata de una paciente de 18 años de edad, que acude a la consulta dental por dolor agudo en la pieza dentaria 3.6 y dolor de 9 meses de evolución en la cara interna del pie izquierdo. Al examen radiográfico, se observó ausencia de las piezas dentarias 1.7, 2.7, 2.8, 3.8 y 4.8, además en el pie izquierdo se vio la presencia de un hueso navicular accesorio. Es interesante proponer esta rara asociación, de clara herencia autosómica dominante, dado que la agenesia dental y la presencia del hueso navicular accesorio, poseen una prevalencia semejante, lo que hace que pueda existir una nueva asociación sindrómica probablemente relacionada con la ausencia de PAX9.

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

    2016-01-01

    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

    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.

    1987-01-01

    Caries, or the decay of teeth are difficult to automatically detect in dental radiographs because of the small area of the image that is occupied by the decay. Images of dental radiographs has distinct regions of homogeneous gray levels, and therefore naturally lead to a segmentation based automatic caries detection algorithm. This paper describes a method for caries detection based on a multiclass, area independent thresholding and segmenting scheme. This multiclass thresholding algorithm is an extension of the uniform error threshold, an area independent, distribution free thresholding method used for images of only two classes of objects. The authors first consider the problem of caries detection and the image features that characterize the presence of caries. Next, the uniform error threshold is reviewed, and the general multiclass uniform error threshold algorithm is presented. This algorithm is used to automatically detect caries in dental radiographs

  1. Improving osseointegration of dental implants.

    Science.gov (United States)

    Elias, Carlos Nelson; Meirelles, Luiz

    2010-03-01

    In the beginning of implantology, the procedures adopted for treating patients were performed in two surgical phases with an interval of 3-6 months. Nowadays, it is possible to insert and load a dental implant in the same surgical procedure. This change is due to several factors, such as improvement of surgical technique, modifications of the implant design, increased quality of implant manufacturing, development of the surgical instruments' quality, careful patient screening and adequate treatment of the implant surface. The clinical results show that adequate treatment of surfaces is crucial for reducing healing time and treating at-risk patients. The surface properties of dental implants can be significantly improved at the manufacturing stage, affecting cells' activity during the healing phase that will ultimately determine the host tissue response, a fundamental requirement for clinical success. This review focuses on different types of dental implant surfaces and the influence of surface characteristics on osseointegration.

  2. Dental worm disease.

    Sabbatani, Sergio; Fiorino, Sirio

    2016-12-01

    During human evolution, the period in which groups of humans stopped harvesting fruits and seeds growing wild and introduced the cultivation of cereals as well as the domestication of animals represents a very important event. This circumstance had a considerable impact on human pathocenosis, increasing the risk of infectious diseases of animal origin. The aim of this review was to summarise the archaeological and palaeo-pathological evidence in the literature concerning this topic. Starting from early prehistory (about 1.5 million years ago) up to the historical period, several authors have described the changes in human habits and the consequent changes in food supply, leading to the transition from a protein- to a carbohydrate-rich diet across a broad interval of time. This led to additional problems for human health. The increased accumulation of carbohydrate debris in the odonto-stomatological apparatus, without the appropriate use of hygiene in the oral cavity, increased the risk of infectious disease involving the mouth. Therefore, since the Neolithic period there has been a higher risk of tooth caries, abscesses, deep infection of the teeth roots, reaching also the mandibular and maxillary bone. Several hypotheses have been proposed by the distinct civilizations, which have alternated in the different ages, to explain the cause of these human health problems, including the idea that a "dental worm" could be involved in this process, such as in the Sumerian period. We describe and discuss further modifications of this theory, developed in Egypt, Assyria, Babylon, China, Greece, in Etruscan cities and in Rome in ancient times as well as in the Middle Ages, and the evolution of scientific thought on this topic in the past 300 years. In addition, the results of some palaeo-pathological studies, which were performed on human remains, such as the maxillary bone and teeth, mainly in different geographical areas in Italy, are examined and reported.

    Full Text Available Dado que en la actualidad hay mayores posibilidades para practicar una lengua extranjera en su contexto natural con nativohablantes, es imprescindible poseer una cierta competencia intercultural a fin de que este diálogo pueda llevarse a cabo exitosamente. Sin embargo, los libros de texto convencionales editados en el país de origen de la lengua estudiada difícilmente pueden cubrir este requisito, puesto que las particularidades culturales de una sociedad sólo se vuelven interculturales al compararlas con la cultura de los alumnos. En el artículo presente se proponen varios ejercicios enfocados al aprendizaje intercultural en donde no sólo se aprenden las normas, reglas y actitudes de la cultura meta, en este caso de Alemania, Austria y Suiza, sino que también se estimula la reflexión sobre las de la cultura propia. Esta sensibilización cultural es indispensable para lograr una comunicación equitativa entre personas de diferentes culturas.

    2009-10-01

    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.

    Rustemeyer, P.; Eich, H.T.; John-Mikolajewski, V.; Mueller, R.D.

    1999-01-01

    Purpose: The intention of this study was to reduce patient dose during dental CT in the planning for osseointegrated implants. Methods and Materials: Dental CTs were performed with a spiral CT (Somatom Plus 4, Siemens) and a dental software package. Use of the usual dental CT technique (120 kVp; 165 mA, 1 s rotation time, 165 mAs; pitch factor 1) was compared with a new protocol (120 kVp; 50 mA; 0.7 s rotation time; 35 mAs; pitch factor 2) which delivered the best image quality at the lowest possible radiation dose, as tested in a preceding study. Image quality was analysed using a human anatomic head preparation. Four radiologists analysed the images independently. A Wilcoxon rank pair-test was used for statistic evaluation. The doses to the thyroid gland, the active bone marrow, the salivary glands, and the eye lens were determined in a tissue-equivalent phantom (Alderson-Rando Phantom) with lithium fluoride thermoluminescent dosimeters at the appropriate locations. Results: By mAs reduction from 165 to 35 and using a pitch factor of 2, the radiation dose could be reduced by a factor of nine (max.) (e.g., the bone marrow dose could be reduced from 23.6 mSv to 2.9 mSv, eye lens from 0.5 mSv to 0.3 mSv, thyroid gland from 2.5 mSv to 0.5 mSv, parotid glands from 2.3 mSv to 0.4 mSv). The dose reduction did not lead to an actual loss of image quality or diagnostic information. Conclusion: A considerable dose reduction without loss of diagnostic information is achievable in dental CT. Dosereducing examination protocols like the one presented may further expand the use of preoperative dental CT. (orig.) [de

    This work is devoted to the optimization of fluorescence dental calculus diagnostics in optical spectrum. The optimal wavelengths for fluorescence excitation and registration are determined. Two spectral ranges 620 - 645 nm and 340 - 370 nm are the most convenient for supra- and subgingival calculus determination. The simple implementation of differential method free from the necessity of spectrometer using was investigated. Calculus detection reliability in the case of simple implementation is higher than in the case of spectra analysis at optimal wavelengths. The use of modulated excitation light and narrowband detection of informative signal allows us to decrease essentially its diagnostic intensity even in comparison with intensity of the low level laser dental therapy.

    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

    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.

    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.

    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.

    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.

    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.

  1. Radiographic signs and diagnosis of dental disease

    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

    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.

    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)

    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.

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

    To 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.

    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.

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

    2012-01-01

    To determine the capacities of radiologic studies in the examination of patients with dental anomalies. One hundred and twenty patients with dental anomalies were examined. Conventional X-ray and high-technology radiology techniques (multislice spiral computed tomography (MSSCT) and cone-beam computed tomography (CBCT)) were used. Orthopantomography is the most common method for radiologic examination of patients with dental anomalies. However, X-ray procedures do not provide complete information on the position and status of an abnormal tooth, which is required to define further patient management tactics. While planning the management, MSSCT and CBCT were performed in 56 (46.7%) and 64 (53.3%) patients, respectively. In addition, 72 (60.0%) patients in whom orthodontic treatment had been recommended at the first stage underwent MSSCT or CBCT following 7 months. CBCT showed that 4 (3.3%) patients had dental ankylosis previously undiagnosed by MSSCT. The high-technology radiology techniques could assess the position of a tooth in relation to its important anatomic structures and identify the comorbidity that keeps from being treated. MSSCT and CBCT can make in full measure the topical diagnosis of abnormal teeth and hence choose an optimal algorithm for comprehensive treatment of patients.

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

    The aim of this study was to compare radiation exposure in panoramic radiography (PR), dental CT, and digital volume tomography (DVT). An anthropomorphic Alderson-Rando phantom and two anatomical head phantoms with thermoluminescent dosimeters fixed at appropriate locations were exposed as in a dental examination. In PR and DVT, standard parameters were used while variables in CT included mA, pitch, and rotation time. Image noise was assessed in dental CT and DVT. Radiation doses to the skin and internal organs within the primary beam and resulting from scatter radiation were measured and expressed as maximum doses in mGy. For PR, DVT, and CT, these maximum doses were 0.65, 4.2, and 23 mGy. In dose-reduced CT protocols, radiation doses ranged from 10.9 to 6.1 mGy. Effective doses calculated on this basis showed values below 0.1 mSv for PR, DVT, and dose-reduced CT. Image noise was similar in DVT and low-dose CT. As radiation exposure and image noise of DVT is similar to low-dose CT, this imaging technique cannot be recommended as a general alternative to replace PR in dental radiology. (orig.)

    Radiography and radiographic examination of the patient form most valuable diagnostic tool in providing comprehensive dental care. The safe and effective use of the X-ray equipment is important for the protection of the patient, other members of the public and all members of the dental team. For patients, the risk that is associated with exposure to X-rays must always be weighed against the clinical benefit of an accurate diagnosis. The risks associated with the exposure to the X-rays during the radiographic examination of the patient must be minimised by meticulously adhering to good practice and thus carefully managing the use of dental radiological procedures. The dentist or the personnel who is the license holder for the X-ray equipment is ultimately responsible for the radiation safety at the workplace. One important method in limiting the possible risk of radiation exposure at workplace is the correct design of an X-ray room. This paper is aimed at discussing the guidelines and recommendations on X-ray room designs in dental radiology in order to facilitate radiation control and safe working conditions for radiation workers as well as the public.

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

Por lo tanto, se hace necesario avanzar en una transición cultural que se pueda comprender como un cambio de época y no sólo como una época de cambios. Para llevar a cabo esta transformación, se deben resolver las con-tradicciones existentes entre el neodesarrollismo y el postdesarrollo, por supuesto, a favor de éste último.

  3. Salivary biomarkers for dental caries.

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

    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.

    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.

    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.

    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.

    Library and academic websites are among the most reliable Internet resources available today. Schools of all types use the Internet as a means of sharing information; and libraries provide broader access to their collections via the Web. For researchers seeking specific, authoritative resources on dental history, library and dental school websites are most helpful in identifying print and online resources, in describing manuscript collections, and in presenting a history of the host institution. A library site often can provide sufficient information online to eliminate the need for an in-person visit to the library. On the other hand, a library site may tantalize the historian with enough information on unique collections that a trip can be justified.

  1. Microbiologic aspects of dental plaque and dental caries.

    Science.gov (United States)

    Marsh, P D

    1999-10-01

    Dental plaque is an example of a microbial biofilm with a diverse microbial composition; it is found naturally on teeth and confers advantages to the host, for example, by preventing colonization by exogenous, and often pathogenic, micro-organisms. In individuals with a high frequency sugar diet, or with a severely compromised saliva flow, the levels of potentially cariogenic bacteria (acid-producing and acid-tolerating species) can increase beyond those compatible with enamel health. This article discusses antimicrobial strategies to control dental caries, including; reducing plaque levels, in general or specific cariogenic bacteria in particular, by antiplaque or antimicrobial agents; reducing bacterial acid production by replacing fermentable carbohydrates in the diet with sugar substitutes, or by interfering with bacterial metabolism with fluoride or antimicrobial agents.

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

    2015-01-01

    Dental caries is a chronic infectious disease resulting from the penetration of oral bacteria into the enamel and dentin. Microorganisms subsequently trigger inflammatory responses in the dental pulp. These events can lead to pulp healing if the infection is not too severe following the removal of diseased enamel and dentin tissues and clinical restoration of the tooth. However, chronic inflammation often persists in the pulp despite treatment, inducing permanent loss of normal tissue and reducing innate repair capacities. For complete tooth healing the formation of a reactionary/reparative dentin barrier to distance and protect the pulp from infectious agents and restorative materials is required. Clinical and in vitro experimental data clearly indicate that dentin barrier formation only occurs when pulp inflammation and infection are minimised, thus enabling reestablishment of tissue homeostasis and health. Therefore, promoting the resolution of pulp inflammation may provide a valuable therapeutic opportunity to ensure the sustainability of dental treatments. This paper focusses on key cellular and molecular mechanisms involved in pulp responses to bacteria and in the pulpal transition between caries-induced inflammation and dentinogenic-based repair. We report, using selected examples, different strategies potentially used by odontoblasts and specialized immune cells to combat dentin-invading bacteria in vivo.

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

    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.

    Salivary gland doses incurred during dental radiography were measured by phantom dosimetry, and these dose data and data obtained during a two-week survey of Hiroshima and Nagasaki dental hospitals and clinics were used to estimate the respective doses to members of the populations of the two cities. The results obtained were used to supplement previously determined doses to the thyroid gland, lens, and pituitary gland from dental radiography. No significant differences in doses were observed by age, sex or city. Doses to the salivary glands during dental radiography are probably not sufficiently large to cause bias in assessments of atomic bomb survivors for late radiation effects. However, the steadily increasing use of dental radiography underscores the need for continued monitoring of dental radiography doses in the interests of these assessments. (author)

    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.

    Full Text Available Si algo ha marcado al género operístico desde sus inicios ha sido el público que ha asistido a los espectáculos que se representaban en sus teatros. En el siglo XX, con la aparición del cine, la ópera sufre una crisis de audiencia, el público tiene un espectáculo masivo al que asistir, más económico y más cercano al consumo cultural dominante. La ópera pasa a convertirse en un espacio para una élite capaz de pagar los altos precios de los abonos. En la actualidad diversas decisiones tomadas por teatros de ópera están provocando que el interés por el género crezca en una sociedad posmoderna en la que la tecnología parece haber agotado los límites espaciales y temporales. Óperas con libretos basados en películas o en personajes de la contemporaneidad, que exhiben prodigios técnicos visuales y sonoros, realizados éstos por grandes figuras del arte y del diseño. Un concepto de la ópera que vuelve a ser un espectáculo que abarca todas las disciplinas, y que ha asumido la evolución que la tecnología ha aportado a éstas con total naturalidad.

    This work is devoted to the optimization of fluorescence dental calculus diagnostics in optical spectrum. The optimal wavelengths for fluorescence excitation and registration are determined. Two spectral ranges 620 – 645 nm and 340 – 370 nm are the most convenient for supra- and subgingival calculus determination. The simple implementation of differential method free from the necessity of spectrometer using was investigated. Calculus detection reliability in the case of simple implementation is higher than in the case of spectra analysis at optimal wavelengths. The use of modulated excitation light and narrowband detection of informative signal allows us to decrease essentially its diagnostic intensity even in comparison with intensity of the low level laser dental therapy

    1980-01-01

    Intra-oral dental X-ray apparatus for panoramic dental radiography is described in detail. It comprises an electron gun having an elongated tubular target carrier extending into the patient's mouth. The carrier supports an inclined target for direction of an X-ray pattern towards a film positioned externally of the patient's mouth. Image definition is improved by a focusing anode which focuses the electron beam into a sharp spot (0.05 to 0.10 mm diameter) on the target. The potential on the focusing anode is adjustable to vary the size of the spot. An X-ray transmitting ceramic (oxides of Be, Al and Si) window is positioned adjacent to the front face of the target. The electron beam can be magnetically deflected to change the X-ray beam direction. (author)

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

    Soft skills and hard skills are essential in the practice of dentistry. While hard skills deal with technical proficiency, soft skills relate to a personal values and interpersonal skills that determine a person's ability to fit in a particular situation. These skills contribute to the success of organisations that deal face-to-face with clients. Effective soft skills benefit the dental practice. However, the teaching of soft skills remains a challenge to dental schools. This paper discusses the different soft skills, how they are taught and assessed and the issues that need to be addressed in their teaching and assessment.

  11. Chronic fluoride toxicity: dental fluorosis.

    Science.gov (United States)

    Denbesten, Pamela; Li, Wu

    2011-01-01

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

    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.

    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.

    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.

    2013-01-01

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

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

  10. Occupational hazards to dental staff

    2012-01-01

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

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

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

    Picture Archiving and Communication System (PACS) is difficult to implement in the best of situations, but evidence is growing that the benefits are significant. The aims of this study are to analyze the current status of full PACS and establish successful installation standard of dental PACS. Materials and Methods were based on the investigation of current working status and installation standard of PACS, and observation of variable issues to installation of dental PACS. By September 30, 2004, full PACS implementations in their facilities were 88.1% in specialized general hospitals (37 installations out of total 42 hospitals), 59.8% in general hospitals (144 installations out of total 241 hospitals), 12.3% in medical hospitals (116 installations out of total 941 hospitals) and 3.6% in dental hospitals (4 installations out of total 110 hospitals). Only 4 university dental hospitals currently have installed and are operating full PACS. Major obstacle to wide spread of dental PACS is initial high investments. Clinical environments of dental PACS differed from medical situation. Because of characteristic dental practice, the initial investments for dental PACS are generally much greater than those of medical PACS. Also new economic crisis makes users scruple. The best way to overcome these limitations is to establish an economic installation standard for dental PACS. Also the clear technical communication between the customer and the supplier before both sides are committed to the obstacles are critical to its success.

    Child dental neglect is the failure of a parent or guardian to meet the child's basic oral health needs such that the child enjoys adequate function and freedom from pain and infection, where reasonable resources are available to family or caregiver. The aim of the study is to evaluate the phenomenon of dental neglect among children in Chennai and to associate dental neglect with oral health status of children aged 3-12 years. This is a cross-sectional study involving 478 pairs of parents and children. Dental neglect scale and a questionnaire were used to assess the dental neglect score among parents of the children involved in the study. Oral health status of children was clinically assessed using oral hygiene index, decayed, extracted, filled teeth (def(t)), pulp, ulcers, fistula, abscess (pufa), decayed, missing, filled teeth (DMFT), PUFA as per the World Health Organization criteria and pufa/PUFA index. Student's t-test and one-way ANOVA were used appropriately for statistical analysis using SPSS software version 20.0. A significant higher dental neglect score was reported among the parents who reside in the suburban location (P 3 years (P = 0.001). A significant higher DMFT (P = 0.003), deft (P = 0 Child dental neglect is seen among the parents whose educational qualification was secondary, who reside in the suburban location, and who have not utilized the dental services for more than 3 years in Chennai. This dental neglect results in poorer oral health of children.

    This paper demonstrates how CT can be used with dental software to evaluate prosthetic failure and for planning dental implants when a stent is used. The Food and Drug Administration issued a safety alert for proplast-coated temporomandibular joint prostheses. Prosthetic failure occurs with migration, fragmentation, or bone erosion. Sagittal CT requiring a special head holder can instead be performed with reformatted sagittal images. The technique of dental implant CT changes when a dental stent is used to provide more accurate implant anchorage and planning. Images must be parallel to the occlusal plane. We will demonstrate these techniques and present their rationale

    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

    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).

    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.

    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.

    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.

    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.

    While past research has explored dental students' motivation to study, there is limited understanding in the reasons behind career choice for hygienists/therapists and dental nurses. The aim of this study was to investigate simultaneously the views of students of dentistry, hygiene/therapy and dental nursing in King's College London and explore similarities or differences in career choice. All first-year students were invited to the questionnaire survey, exploring motivation to study using a 23-item instrument. Data were analysed using SPSS v18; statistical analysis included one-way analyses of variance and factor analysis. The overall response rate to the study was 75% (n = 209). Ten out of 23 factors were considered important by more than 80% of respondents, with 'job security' (93.8%), 'desire to work with people' (88%) and 'degree leading to recognised job' (87.5%) being top three. Analysis suggested that 52% of the total variation in motivating influences was explained by four factors: 'features of the job' (26%), 'education/skills' (11%), 'public service' (8%) and 'careers-advising' (7%); at group level 'features of the job' were significantly more important for the direct entrants to dentistry (P = 0.001). The findings suggest that across groups students were motivated to study by common influences reflecting altruistic, but also pragmatic and realistic motives, while 'features of the job' were more important for the direct entrants to dentistry. © 2013 John Wiley & Sons A/S.

Los resultados indican que Santiago es una ciudad de habitantes con temor y que el aumento de la percepción de inseguridad de sus habitantes contrasta con el hecho de que las tasas de victimización se hayan mantenido, más o menos, constantes en los años que precedieron a la encuesta. El temor se relaciona con el abandono del espacio público físico y sociopolítico, así como con el refugio en los espacios y la vida privados. La actitud de resolver los conflictos por medios no pacíficos es frecuente y se asocia en mayor medida con la inseguridad, la actitud negativa hacia la democracia y la falta de expectativas sobre el futuro del país. Los resultados de este estudio respaldan la idea de que para superar el temor la gente tiende a adaptarse a la realidad adoptando una postura conformista, homogeneizando las creencias y los comportamientos, y sobreestimando la fuerza como medio para resolver las diferencias.

Del él puede hacerse también una lectura “burguesa”, como fundamento de la democracia liberal basada en la propiedad privada, con interesantes consecuencias cuando los ciudadanos ven que sus derechos son violados. Este artículo explora cómo va cambiando la definición del derecho a la vivienda a través de la agenda de ONU–Hábitat, y discute los puntos fuertes y débiles de este programa desde una perspectiva antropológica. El análisis incide sobre el hecho de que gran parte de la población mundial ha tenido que encontrar sus propias soluciones a los problemas de vivienda, y aborda los debates en torno a la “regularización” de los asentamientos, la tierra y las viviendas “informales”, a los mercados de la vivienda, y a las implicaciones sociales de los diferentes enfoques al respecto. Se sostiene que el enfoque de las Naciones Unidas, a pesar de su énfasis en la planificación participativa y la universalización del derecho a la ciudad, sigue marginando aspectos más complejos que surgen de las relaciones entre la vivienda, el hábitat y los patrones de sociabilidad. El artículo concluye con la consideración de las condiciones a las que se enfrentan los movimientos sociales que luchan por el derecho a la ciudad, en un contexto de regeneración urbana y gentrificación basado en la clase social, incorporando la comprensión de los procesos microsociales que ofrece la investigación etnográfica, desde una perspectiva multidimensional, sobre las relaciones de poder que han estructurado el reciente desarrollo de las ciudades metropolitanas.

    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

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.

    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.

    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.

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

    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."

    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.

    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.

    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.

    Con ocasión de un estudio de revisión que hemos llevado a cabo recientemente sobre la tuberculosis osteoarticular, *** se ha apreciado un cambio notable en las características y manifestaciones de esta enfermedad.

    Hemos sido testigos del comportamiento de la tuberculosis en los últimos 40 años. Realizamos la tesis profesional en el Hospital de niños de la Misericordia de Bogotá en el año 1950 (86, basada en el análisis de más de 300 enfermos de Mal de Pott tratados con pobres resultados en esa institución en la época prequimioterápica. Efectuamos estudios de control del tratamiento quirúrgico de esa afección en el Hospital Infantil Lorencita Villegas de Santos y publicamos sus resultados en los años 1975,1980 Y1987 (85-87-88. Los pacientes correspondientes a estas nuevas series, ya en la época de la quimioterapia moderna, presentaban un mejor pronóstico vital y funcional. Cuadro 1A.

    En el decenio 1978-1988 asistimos al descenso espectacular de la frecuencia de tuberculosis osteoarticular en las salas de nuestros hospitales. Posteriormente hemos sido igualmente testigos de su lenta y progresiva reaparición.

    El estudio actual nos ha mostrado profundos cambios, como ya se ha dicho, en el comportamiento de la entidad, por lo que estamos de acuerdo en denominarla: La tuberculosis, una enfermedad modificada, diferente a la que hasta hace un década parecía derrotada, vencida por las nuevas drogas y las recientes técnicas quirúrgicas.

    La actual es una enfermedad diferente que ha tomado una fuerza avasalladora que amenaza con volverse resistente al tratamiento específico y dar lugar a una pandemia de incalculables proporciones y de terribles consecuencias para la humanidad.

    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.
