Estudio anatómico del sistema de conductos radicular es del segundo premolar inferior mediante la técnica de diafanización dental

Abstract

Endodontic therapy establishs a fundamental relationship with the dental anatomy of root canals, clean and disinfect them adequately ensures the periapical health of tooth and preserves its function. Omit the preparation of a canal is synonymous of failure and happens in the majority of cases because it is not located or ignore its presence. In order to describe and analyze the anatomy of root canals of the lower second premolar, a transectional descriptive study was designed, the sample consisted of 70 lower premolars seconds teeth which were diaphanized and classified according to the configuration of Vertucci. The type of root canal observed most frequently was the type I with the 88.6%, followed by type IV with 4.3%, type II and III in 2.9%, and type IV observed in 1.4% of the total of the sample analyzed. There were no root canal type VI, type VII and type VIII. It is concluded that the anatomical variations in this tooth may be present, it is important to know all the details and anatomical structures of the system of canals and the different variations that may occur in this tooth.
