Evalúa la profundidad de polimerización y el grado de conversión por medio de la microdureza superficial interna de dos resinas compuestas de nanorelleno utilizando dos lámparas LED; una de segunda generación y la otra de tercera generación. Metodología. En el estudio in vitro, se obtuvieron 75 especímenes que se dividieron en tres grupos de acuerdo al tipo de resina compuesta, dos resinas de nanorelleno “Tetric N-Ceram” (Ivoclar-Vivadent) y “Filtek Z-350 XT” (3M) y una resina Bulk Fill (grupo control) y cada uno de ellos en tres subgrupos según el tipo de unidad de luz, una unidad de luz “halógena” (grupo control), y dos lámparas de luz emitida por diodos (LED-Valo y LED-Elipar), aplicada sobre el espécimen. Se realizó el análisis estadístico, en donde, las variables fueron sometidas a las pruebas de normalidad y homogeneidad por sus varianzas. Las variables p...

The purpose of this study in vitro was to evaluate the tensille strength of adhesive system to the surface of bleached enamel with 10% carbamide peroxide with and without fluoride. We used nine healtly third molars, divided into three groups: Control (unbleached), group I (bleached with 10% Opalescence), group II (bleached with 10% Opalescence PF). Bleaching groups had a period of bleaching of 6 hours per day at 37°C, during 14 consecutive days; the teeth during this period were stored in artificial saliva. We waited 7 days to put a resin block (Filtek Z350,3M) of 5x5x3mm (w,l,h) on the buccal, palate or lingual surface of each tooth, previously we used 35% phosphoric acid (Scothbond, 3M) and an adhesive system (Single Bond 2, 3M). We used a diamond bioactive disc to make a horizontal and vertical cut to obtain the specimens, which were stored in distilled water. After 24 hours, the spe...

This treatment was carried out in a 58 years old male patient, who has had the antecedent of a car crash accident two years before; he loosed several teeth and fractured others. Pulp necrosis and alteration of occlusal plane occurred. Because of the pathologies presented, it was installed a multidisciplinary treatment phase having periodontal, endodontic, surgical and orthodontic procedures, tehe installation of posts, crowns and fixed bridges. Treatment was carried out for five months.

Objetive: Determine the influence of values in the formation of a national defense culture in dental students. Materials and method: an explanatory observational, descriptive study, quantitative, cross, consisting of a random sample (simple random selection) of 192 dental students who were studying the semester 2015-2, was distributed by years of studies was conducted first (n = 42), second (n =44), third (n = 33), fourth (n = 39) and fifth (n = 34). The questionnaire reduced Values Scale Schwartz (PVQ-21) for measuring the variable values and questionnaire validated by Suarez, DG and Montano, YM (based on NATID Scale and studies Cesar Cobos Ruiz) version was applied variable measuring the formation of a culture of National Defense. For statistical analysis, the Kolmogorov-Smirnov test was used, Chi square, Spearman coefficient, frequencies and averages. Results: A reliability coefficien...

Objetivo: Determinar la influencia de los valores en la formación de una cultura de defensa nacional en estudiantes de Odontología. Materiales y método: Se realizó un estudio observacional, descriptivo explicativo, cuantitativo, transversal; constituido por una muestra probabi-lística (selección aleatoria simple) de 192 estudiantes de Odontología que cursaban el semestre 2015-2, se distribuyó según años de estudios: primero (n=42), segundo (n=44), tercero (n=33), cuarto (n=39) y quinto (n =34). Se aplicó el cuestionario de la versión reducida de la Escala de Valores de Schwartz (PVQ-21) para medir la variable valores y el cuestionario validado por Suárez, DG y Montano, YM (basado en la Escala NATID y estudios de César Cobos Ruiz) para medir la variable formación de una cultura de defensa nacional. Para el análisis estadístico se utilizó la prueba de Kolmogorov-Smirnov, ...
