Tooth retention has improved remarkably in the 65-74 age groups, from 7.4 in 1962 to 17.9 in 1986. While younger age groups will require less treatment due to decline in dental caries, older age groups appear to require more treatment than did similar age cohorts in previous generations. Hence, the need for restorative procedures by the United States population will be on an upward trend for the next decade or two.

Los autores han desarrollado una guia clinica para ayudar al dentista a detectar a aquellos pacientes con diabetes no diagnosticada. Metodos.Los autores utilizaron el metodo CART (arbol de clasificacion y regresion, Classification and regression tree para regenerar distintos modelos de prediccion utilizando datos del estudio NHANES III (Tercer Estudio Nacional de Analisis de la Nutricion y la Salud, National Health and Nutrition Examination Survey (1988-1994) y datos del mismo estudio correspondientes al periodo 2003-2004 para su validacion externa. Se clasificaron como pacientes con diabetes no diagnosticada a aquellos que respondian "no" a la pregunta "?Alguna vez le ha dicho el medico que tiene diabetes?" y cuya concentracion plasmatica de glucosa era 126mg/dL, como minimo. Los autores utilizaron datos obtenidos en la exploracion oral para determinar la presencia o ausencia de periodontitis, asi como el perimetro abdominal y datos referidos por los propios participantes sobre su estado de salud, peso, edad, antecedentes medico familiares y raza o etnia. Los autores eligieron el mejor modelo de prediccion por medio de la validacion cruzada iterando diez veces el proceso de validacion simple, asi como metodos de validacion interna y externa con los que valoraron cada modelo de prediccion, comparando la sensibilidad, la especificidad, el area bajo la curva ROC (Receiver Operating Characteristic= y la facilidad de uso de los criterios (N= 7.545). Resultados. La guia clinica final predice la presencia de diabetes no diagnosticada en pacientes dentales con una sensibilidad del 82, 4%, una especificidad del 52, 8% y un area bajo la curva ROC (Receiver Operating Characteristic) igual a 0, 72. Encontraron que el perimetro abdominal, la edad, el estado de salud, la raza o la etnia y el peso referidos por el paciente podian utilizarse para predecir el riesgo de diabetes no diagnosticada (rango: 0, 1-0, 9%). Conclusiones.Los dentistas deben considerar la utilizacion de una guia clinica que incluya los siguientes factores de prediccion: perimetro abdominal, edad, salud oral, peso y raza o etnia referidos por el paciente, asi como cualquier informacion adicional sobre el estado periodontal y los antecedentes medicos familiares de diabetes . Implicaciones clinicas. Esta guia clinica puede ayudar a los dentistas a detectar aquellos pacientes con diabetes no diagnosticada, permitiendo una identificacion precoz de los pacientes dentales que requeriran tratamiento de la diabetes y, por lo tanto, reducir la mordabilidad y los costes sanitarios.

Research paper thumbnail of Strength of evidence linking oral conditions and systemic disease

Compendium of continuing education in dentistry. (Jamesburg, N.J. : 1995). Supplement, 2000

If this extremely common source of chronic infection (dental disease) leads to an increased morbidity and mortality rate, the public health impact of oral disease on millions of Americans would be substantial. Recent studies demonstrate an association between dental and systemic diseases, including systemic infections, cardiovascular disease, pregnancy outcomes, respiratory diseases, and increased all-cause mortality rate. Because there are several common risk factors for oral and systemic diseases, and limitations in published studies, a careful interpretation is needed. Confounding (shared risk factors for both systemic and dental disease) may explain part of the reported associations. It is also plausible that there may be a causal link. It is likely that if there is a causal link, several pathways and mediators coexist, linking oral and systemic...

Five trends have been documented in support of this thesis: the increasing number of elderly and their retention of teeth means there is a greater need for restorative dental care than in previous generations; the elderly have chronic diseases and are taking more medications; younger patients are presenting more frequently with infectious, systemic diseases such as HIV/AIDS. New scientific discoveries are opening new possibilities for patient care, which generate even higher expectations on the part of future consumers of medical and dental services. The health and fitness trend is not a fad; new knowledge regarding diet, nutrition, and exercise is identifying systemic risk factors related to common ...

The VA Dental Longitudinal Study (DLS) provided information on the restorative treatment received by 593 healthy adult males during a 10–year period. Utilization of restorative services was measured by calculating the percentage of surfaces that needed and received treatment, as identified by the DLS examiners by clinical and radiographic examination. Oral examinations were initiated in 1969 with subsequent examinations occurring at approximately 3–year intervals. Personality measures for these individuals were obtained using the EPI‐Q, a shortened form of the Eysenck Personality Inventory.A plot of neuroticism versus the utilization measure yielded a curvilinear relationship suggesting that participants seeking the most dental care scored moderately on the neuroticism scale whi...

An analysis was conducted to project the unmet need for fixed and removable partial dentures in the years 2005, 2010, and 2020. Unmet need was calculated as follows: Total need equals the number of persons in each age cohort multiplied by the percentage who need a fixed or removable partial denture multiplied by the average procedure time required to provide the service. Total unmet need then equals total need minus the annual supply of prosthodontic services delivered by prosthodontists and general practitioners. Projected results indicate that total unmet need will increase from 488 million hours in 2005 to 517 million hours in 2010 and to 560 million hours in 2020. The significance of the results is that unmet prosthodontic need will increase and exceed the supply of services for the foreseeable 20-year future. Practicing dentists will find that a sizable minority of the population will continue to need fixed and removable partial denture services.
