Resumen
Uno de los grandes enigmas de la endodoncia moderna es evitar en lo posible que se produzca un fracaso del tratamiento realizado, se ha propuesto que dicho fracaso puede ser causado por el paso de bacterias a través del foramen apical al no haber un buen sellado hermético y tridimensional del sistema de conductos, los que por activación de nuestro sistema inmunológico se producirá una respuesta inflamatoria. El sellado apical correcto con la utilización de conos de gutapercha y un cemento sellador van a impedir que se produzca el paso de estas bacterias, pero la presencia de diversos fluidos y humedad pueden hacer que se produzca solubilidad y permita la filtración bacteriana, el propósito de este estudio fue evaluar el sellado apical in vitro que se produce utilizando el sistema rotatorio de Ni-Ti Mtwo, el cemento sellador TopSeal y aplicando la técnica de condensación lateral en frio, para lo cual se emplearon 10 dientes anteriores previamente extraídos a los cuales se les realizo el respectivo proceso endodóntico, una vez concluido el tratamiento endodóntico se los procedió a sumergir en tinta china para poder evidenciar la filtración. Los resultados revelaron que dentro de los procedimientos que hemos realizado para poder evidenciar resultados, concluimos que en la muestra de 10 dientes a las que se le realizo el tratamiento endodóntico adecuado y el sellado posterior del sistemas de conductos se evidencio que de la muestra de 10 dientes que corresponde a un 100%, el 80 % de esta muestra evidenciaron filtración hasta los 2mm desde apical, mientras que el 20% de la muestra evidenciaron filtración mas allá de los 10mm.

One of the great enigmas of modern endodontics is avoided whenever possible treatment failure made from occurring, it is proposed that this failure may be caused by the passage of bacteria through the apical foramen in the absence of a good sealing and dimensional system of ducts that by activating our immune system will produce an inflammatory response. Apical proper sealing with the use of gutta-percha and sealer cement will prevent the passage of these bacteria occur, but the presence of various fluids and humidity might occur and allow solubility bacterial filtration, the purpose of this study was to evaluate the in vitro apical seal produced using rotary Ni-Ti system Mtwo, the sealer and applying TopSeal lateral condensation in cold, for which previously removed anterior teeth 10 are employed which underwent endodontic the respective process, once completed endodontic treatment was proceeded to dip into the ink to show the filtration. The results revealed that within the procedures we have performed to demonstrate results, we conclude that in the sample of 10 teeth to which he conducted the proper endodontic treatment and subsequent sealing of ductwork was evidenced that the sample of 10 teeth corresponding to 100%, 80% of this sample showed filtration from apical to 2mm, while 20% showed sample filtration beyond 10mm.
