Resumen
El presente trabajo tiene como finalidad demostrar que los tratamientos de conductos son intervenciones odontológicas que demandan de concentración y conocimientos para realizar cada una de sus fases, la biomecánica endodontica esta constituidas por fases bien diferenciadas ligadas íntimamente al éxito del tratamiento, tales fases están constituidas por la conformación, irrigación y obturación, la conformación de conductos radiculares en los procedimientos endodonticos es una fase de vital importancia durante el tratamiento, ya que, la correcta conformación garantiza una buena irrigación y obturación tridimensional de conductos, una conformación exitosa es aquella que respeta la anatomía del conducto de la pieza dentaria tratada, busca la eliminación de todo el tejido pulpar, permite lavar el conducto para eliminar detritos y virutas acumulados en su interior provocadas por los cortes de dentina luego de la instrumentación, y por ultimo permite secar el conducto para luego poder realizar una obturación con selle hermético. Este objetivo puede ser conseguido mediante diversas técnicas e instrumentos los mismas que se se seleccionan dependiendo si el caso es una biopulpectomia o necropulpectomia y a su vez considerado la morfología radicular de cada pieza dental, en el presente caso se encontró un premolar inferior con sombra radiolucida en apical y con curvatura y estreches del conducto radicular, en el cual se eligió el instrumental idóneo para el manejo de conductos curvos y estrechos, dichos instrumentos son el sistema de limas protaper las cuales las hay en versión manual o también en versión rotatoria las mimas que deben ser activadas por un micromotor para poder realizar su función, este sistema de limas posee las características necesarias para instrumentar este tipo de conductos curvos que debido a su morfología aumentan el grado de dificultad en su tratamiento.
This paper aims to demonstrate that root canals are dental procedures that require concentration and knowledge to perform each of its phases, endodontic biomechanics is composed of distinct phases intimately linked to the success of treatment, such phases are formed by forming, irrigation and sealing, shaping root canals in endodontic procedures is a phase vital during treatment, since the correct conformation ensures good irrigation and dimensional root canal filling, a successful formation is one that respects the canal anatomy of the treated tooth, seeks the removal of all pulp tissue, it allows to wash the duct to remove debris and shavings accumulated inside caused by cuts dentin after instrumentation, and finally allowed to dry conduit then able to make a seal with hermetic seal. This objective can be achieved by various techniques and instruments the same as selected depending on whether the case is a biopulpectomia or necropulpectomia and in turn considered the root morphology of each tooth, in this case a lower premolar with radiolucent shadow was found in apical and curvature and narrowness of the root canal in which the ideal instrument for handling curved and narrow tubes was selected, these instruments are system files ProTaper which there are in manual or in rotating version mimas that must be activated by a micromotor to perform its function, this system has the files necessary to implement this type of curved ducts due to their morphology increase the degree of difficulty in its treatment characteristics.
