Prevalencia de raíces supernumerarias en molares inferiores, evaluación en tomografía computarizada de haz de cono (cone beam) de una base de datos

Abstract

Introduction. The anatomy of the root canal in these roots is very complex and unpredictable, so for endodontic treatment can succeed as restorative treatment; is necessary to know the internal morphology and locate all root canals, clean and completely seal them with a suitable material.

Objective. To determine the prevalence of an anatomical variant on the mandibular molars, this supernumerary root is typically distributed lingually and was termed radix entomolaris, or in a location buccal called radix paramolaris.

Avoid errors during endodontic treatment procedure requires a clinical approach adapted for the diagnosis and treatment of root canal.

Materials and methods. This study analyzed 290 CT scans cone beam to determine the prevalence of a third root in lower molars, using a database.

Results. The prevalence found in this study was of 0.34 % in a male patient
