La diabetes mellitus como factor de riesgo de pérdida dentaria en la población geriátrica / Diabetes Mellitus as a risk factor for loss of teeth in geriatric populationLa diabetes mellitus como factor de riesgo de pérdida dentaria en la población geriátrica / Diabetes Mellitus as a risk factor for loss of teeth in geriatric populationLa diabetes mellitus es un reconocido factor que agrava la enfermedad periodontal. Con el objetivo de determinar su posible relación con la pérdida dentaria se realizó una investigación descriptiva y transversal de grupo y control, utilizando como muestra 42 ancianos diabéticos (grupo de estudio) y 42 no diabéticos (grupo control), pertenecientes al consultorio médico 272 de la Clínica Estomatológica "Guamá", área de salud "Turcios Lima", Pinar del Río, durante el segundo semestre del año 2008. Se utilizó el método estadístico Chi cuadrado y valor porcentual. La mayoría de los ancianos se encuentran en el grupo de edad de 60 a 69 años, con una higiene bucal mala, tanto de diabéticos 21(50,0%) como no diabéticos 19 (45,2%). Predominó la pérdida dentaria en los diabéticos, existiendo 12 (28,5%) que no poseen ningún diente en el maxilar y 21 (50%) que no poseen ningún diente en la mandíbula. La gingivitis fue la enfermedad periodontal más frecuente encontrada, presente en 17 ancianos (43,5%), con mayor incidencia en los diabéticos 11 (28,2%). El 90, 4% de los diabéticos tenía necesidad de prótesis, en su mayoría prótesis totales 29 (76, 3%). Palabras clave: Ansiedad, higiene bucal, educación, diabetes mellitus, factores de riesgo. ABSTRACT Diabetes Mellitus is a well-recognized risk factor that worsens periodontal disease. Aimed at determining the possible relation between this disease and loss of teeth a descriptive and cross-sectional research was conducted with a test group and a control one using a sample of 42 diabetic-elderly patients (test group) and 42 non-diabetic patients (control group), belonging to No- 272 Doctor's Office at "Guama" Dentist's Clinic, "Turcios Lima" health area, Pinar del Rio during the second term of 2008. The chi-squared test and percentage value were used as statistical methods. The majority of the elderly belonged to the group of ages 60 to 69; presenting a poor dental hygiene in diabetic 21 (50, 0%), and similar to non-diabetic 19 (45, 2%). Loss of teeth prevailed in diabetic being toothless in the maxillary 12 (28, 5%) and 21 (50%) toothless in the jaw. Gingivitis was the most frequent periodontal disease found 17 (43, 5%) showing a higher incidence in diabetic patients 11 (28,2%). The 90,4% of the diabetic patients needed dentures, the majority of them needed total dentures 29 (76, 3%). Key words: Anxiety, oral hygiene,education, diabetes mellitus,risk factors.

In different previous studies it has been reported that ultrasound shortens the healing periodof fresh fractures (Leung et al, 2004) and promotes the healing of refractory fractures (pseudoarthrosis,delayed union fractures), shortening the treatment perio... see more

Restauración estética sin soporte metálico por vía directa como alternativa en el cierre de diastemas generalizados Restauración estética sin soporte metálico por vía directa como alternativa en el cierre de diastemas generalizadosIntroducción: La restauración estética sin substrato metálico en el sector anterior se puede efectuar por método directo. La misma logra alcanzar un aspecto más natural que las restauraciones indirectas y resistir las cargas oclusales de igual modo, lo que posibilita no solo reconstruir dientes sino transformarlos. Esto hace ideal el procedimiento para el cierre de diastemas generalizados, los cuales habitualmente son resueltos a través de atención secundaria de prótesis u ortodoncia, soluciones de alto costo y suponen mayor incomodidad al paciente. Objetivo: Describir el procedimiento de restauración estética sin soporte metálico por vía directa con nanocomposite, como alternativa terapéutica para el cierre de diastemas generalizados. Presentación del caso: Se describe el tratamiento impuesto a un paciente de 53 años con antecedentes de traumatismo dentario con avulsión del 22 y fracturas complicadas de corona en 12, 11 y 21 hace alrededor de 15 años, por lo que recibió tratamientos pulporadiculares radicales. El paciente presentaba cambios de coloración severa, además de la presencia de diastemas generalizados en el sector anterior maxilar, para lo cual se le realizó tratamiento restaurador integral por vía directa y se seleccionó nanocomposite híbrido. Conclusiones: El tratamiento cosmético con nanocomposite sin sustrato metálico es una alternativa terapéutica viable en el cierre del diastema generalizado por vía directa, aun en pacientes con traumatismos severos, en dientes discrómicos con tratamiento pulporadicular radical. Palabras clave: Cierre de diastemas generalizados, cosmética dental, nanocomposite para muñones adhesivos, estética dental, resina compuesta dental. ABSTRACTIntroduction: The aesthetic restoration without metallic substratum in the anterior sector can be performed through direct method. It allows to reach a more natural aspect that the indirect restorations and to resist the occlusal loads in the same way, making possible not only to reconstruct teeth but to transform them, which makes ideal this procedure in the closing of widespread diastema those which are habitually resolved through secondary attention of prosthodontics or orthodontics, solutions of high cost and greater annoyance to the patient. Objective: To describe the procedure of aesthetic restoration without metallic support through direct method with nanocomposite as therapeutic alternative for the closure of widespread diastema. Case presentation: It is described the treatment imposed to a 53 year-old patient with antecedents of dental trauma with extraction of the 22 and complicated crown fractures in 12, 11 and 21 around 15 years ago, for which he received radical pulp-radicular treatments. The patient presented changes of severe coloration, besides the generalized diastema presence in the maxillary anterior sector, for which an integral restoration treatment through direct method was carried out by using a hybrid nanocomposite. Conclusions: The cosmetic treatment with nanocomposite without metallic substratum is a viable therapeutic alternative in the closing of the generalized diastema through direct method, even in patients with severe traumatized, dyschromia teeth with a radical pulp-radicular treatment.Key words: Closure of generalized diastema, dental cosmetics, nanocomposites for stumps adhesives, dental esthetics, permanent dental restoration.
