Dentro de las profesiones de salud, la odontología requiere un cierto nivel de habilidad manual. El estudiante realiza diversos procedimientos durante la formación de pregrado en asignaturas del nivel preclínico y clínico en busca de lograr la competencia profesional, y entre las que tienen mayor complejidad está el tratamiento endodóntico. Se afirma que la destreza manual del estudiante de odontología es un aspecto psicomotriz que puede influir en el desempeño en cursos preclínicos y clínicos, sin embargo, no se conoce si el nivel de destreza se relaciona con el aprendizaje motor de procedimientos operatorios complejos como la preparación biomecánica en la endodoncia al utilizar instrumentos mecanizados de última generación para la preparación de conductos radiculares. El objetivo de esta investigación fue determinar la relación entre la destreza manual y el aprendizaje...

El tratamiento endodóntico depende de diversos aspectos, entre ellos de la vitalidad de la pulpa. En el caso de las biopulpectomías que por diversas circunstancias deban de postergar su culminación con una cita adicional, existe una controversia sobre el tipo de medicamento intraconducto entre sesiones a usar. Dentro de ellos las más aceptadas son las pastas de hidróxido de calcio por sus propiedades como antimicrobiano y favorecedor de la reparación tisular, sin embargo, se ha reportado también la toxicidad de esta pasta sobre los tejidos periapicales. Sin embargo, estos efectos pueden ser modulados por el vehículo de la pasta. En esta investigación se propone el gel de Aloe vera como vehículo de la pasta de hidróxido de calcio, ya que posee características fisicoquímicas que pueden disminuir su toxicidad, y por sus propiedades biológicas pueden mejorar la respuesta tisula...

The aim of this study was to demonstrate that the use of irrigating solutions in surgical procedures does not alter both inflammation processes and tissue repair. Four (04) groups were formed containing 15 rats each. After being dosed with general anaesthesia, they underwent osteotomy in the tibia with tungsten carbide burs and irrigation for 15 seconds, using the following solutions in each group: A) 0,12 % chlorhexidine with cetylpyridinium 0,05 %, B) 0,12 % chlorhexidine with aspartame; C) hexetidine 0,1 %; D) 0,9 % sodium chloride. After 3, 7 and 15 days of surgery, the rats were sacrificed and tissue samples were removed for histopathological analysis. The results showed that groups in which chlorhexidine with cetylpyridinium, and chlorhexidine with aspartame were used, less inflammatory process were found than in groups of sodium chloride and hexetidine. On the process of tissue re...

The aim of the study was to evaluate the possible modifications in the arterial pressure, corporal weigh and creatinine cleareance in urine gathered during 24 hours, in healthy young people, under therapy with two non steroidal anti inflammatory drugs (NSAID’s); one of them not selective to Ciclooxigenase (Ibuprofen) and a selective inhibitor of Ciclooxigenase - 2 (Celecoxib), during three days in standardized dose, in comparison with a control group that was administered placebo, in a double blind study. The results indicate that there are not statistically significant differences among the three groups, for the clinical and laboratory evaluated parameters (p <0,05). We conclude that a short term therapy with the used NSAID’s doesn’t produce clinical impact modifications in the arterial pressure, corporal weigh and creatinine cleareance in urine gathered during 24 hours.
