Objective: the objective of this study was to determine and analyze the wettability of irrigating solutions of root canal treatment in bovine tooth dentin surface. Materials and method: For the study were prepared 15 acrylic blocks :40 mm x 30 mm x 8 mm wherein a surface exposed tooth dentin of bovine tissue. There were used as test irrigants: 5,25% sodium hypochlorite solution, 0,12% chlorhexidine gluconate, water saturated with calcium hydroxide and sodium chloride solution 9/1000. On dentin surface was deposited a calibrated drop of irrigating solution, this sessile drop contact with dentin surface showed many forms which were photographed to measure them with a conveyor provided the angle (contact angle). Results showed that Chlorhexidine Gluconate 0,12 %, established a contact angle with an average of 41.33°, followed by water saturated with calcium hydroxide (43.23º), sodium hypo...

Objetivo: Determinar y analizar la capacidad de humectancia de soluciones irrigantes usadas en el tratamiento de conductos radiculares sobre la superficie dentinaria de dientes de bovino. Materiales y método: Estudio experimental in vitro. Se preparó 60 bloques de acrílicoautocurado de 40 mm x 30 mm x 8 mm donde una superficie expone tejido dentinario de diente de bovino. Los irrigantes de prueba fueron: solución de hipoclorito de sodio al 5,25%, gluconato de clorhexidina al 0.12%, suero fisiologico y agua de cal. En la superficie de dentina se depositó una gota calibrada de las soluciones irrigantes, estas gotas sésiles en contacto con dentina mostraron muchas formas las cuales fueron foto-grafiadas para posteriormente superponerle el trazo de una tangente desde el punto de contacto y sobre el ecuador del arco establecido, el ángulo resultante fue medido con un transportador esta...

Bioethics arises from the need to respond and try to solve the major conflicts that arise in society. Bioethics is a modern term that is attributed paternity Van Rensselaer Potter (1970) by publishing the article “Bioethics, the science of survival,” Potter establishes the existence of a close relationship between the world of life sciences, his deeds and ethical values, bioethics subsequently primarily it related to medical ethics. Tom L. Beauchamp and James F. Childress published “Principles of biomedical ethics” 1979, being considered a classic text in biomedical ethics, in which four bioethical principles states: autonomy, non-maleficence, beneficence and justice. Analysis and bioethical reflection are essential in the practice of the dentist, this will allow a clinical practice based on values, which would involve all health personnel, guiding strategies to address adequatel...

Objetive: Determine the efficiency of the method of estimating age based on the coronal tooth index. Materials and method: The method of index Cavity Coronal Pulp was performed on 432 teeth of the fourth mandibular quadrant (first premolar = 129, second premolar = 104, first molar = 113 and second molar = 86) evaluated in digital panoramic radiographs belonging adult individuals, aged 20 and 40, who attended the Imaging Department of the Faculty of Dentistry, National University of San Marcos and compared with the chronological age of the individual. Results: The results of the correlations were significant, especially for the second molars in males (r = 0.814, r2 = 0.663). Conclusion: The application of the method of dental coronary index is efficient and linear regression equation found larger sample approach in estimating the age of the individual.

Objetivo: Determinar la eficiencia del método de estimación de la edad basada en el índice coronal dentario. Materiales y método: Se realizó el método de índice de la cavidad coronal pulpar en 432 piezas dentarias del cuarto cuadrante mandibular (primera premolar=129, segunda premolar=104, primera molar=113 y segunda molar=86), evaluadas en radiografías panorámicas digitales, pertenecientes a individuos adultos, de 20 y 40 años, que acudieron al Servicio de Imagenología de la Facultad de Odontología de la Universidad Nacional Mayor de San Marcos y se comparó con la edad cronológica de cada individuo. Resultados: Los resultados de las correlaciones fueron significativas, especialmente para los segundos molares en el sexo masculino (r = 0.814, r2 = 0.663). Conclusión: La aplicación del método de índice coronario dental es eficiente y la ecuación de regresión lineal enco...

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, ...
