Resumen
La anatomía de los conductos radiculares puede representar un reto clínico para los profesionales ya que se requiere de pericia clínica para localizar, permeabilizar y sellar con éxito el sistema de los conductos radiculares. El objetivo de esta investigación que se desarrolló, es para analizar con mayor profundidad la morfología apical, y en si la relación que existe entre el foramen apical y el vértice radicular en raíces mesiales de primeros molares inferiores permanentes, a través de un estudio invitro. Se seleccionaron 18 molares mandibulares, donde se cortó la raíz distal, quedando en estudio la raíz mesial, se realizó la instrumentación mecánica ayudados con el uso de una fresa redonda para realizar las aperturas, las limas utilizadas fueron las de tipo K de la serie n°10. Previamente utilizamos la radiografía con toma preoperatoria, posteriormente se tomó las radiografías postoperatorias con el instrumento introducido sobrepasando el foramen apical principal, para de esta manera observar la comparación y realizar la observación clínica y radiográficamente. Los resultados de esta comparación indican que sólo alrededor del 50% de los molares estudiados coincide su foramen con el vértice radicular, mientras que el resto mantiene su foramen hacia vestibular un 30% y hacia lingual 20%, tomando en cuenta en este estudio sólo el foramen principal de un solo conducto. Esto nos sirve como ayuda ya que la morfología apical de los conductos tiene efectos consecuentes posoperatorios importantes sobre el protocolo del tratamiento. La anatomía apical que presentan las raíces de los primeros molares mandibulares presenta grandes variaciones complejas.

The anatomy of the root canal can be a clinical challenge for professionals as it requires clinical expertise to locate, permeable and successfully seal the root canal system. The objective of this research was developed, is to further analyze the apical morphology, and whether the relationship between the apical foramen and root apex in mesial roots of first permanent mandibular molars, through an invitro study. 18 mandibular molars, where the distal root was cut were selected for further study being conducted mesial, se root aided mechanical instrumentation using a round bur for openings, limes used were K-type series n # 10. Previously we used with preoperative radiograph taken subsequently postoperative radiographs were taken with the instrument introduced surpassing the main apical foramen, so watch for comparison and perform clinical and radiographic observation. The results of this comparison indicate that only about 50% of the molars studied the foramen match with the root apex, while the rest remains foramen labial and lingual 30% to 20%, taking into account only the main foramen a single conduit. This gives us help as the apical duct morphology has important effects on the treatment protocol. The apical anatomy having roots mandibular first molars complex presents large variations.
