Endodontic Treatment of A Mandibular First Premolar with Three Canals

Main Article Content

Amornrat Boonsiri

Abstract

The success of endodontic treatment is dependent on the cleaning, shaping, and obturation of the root canal system, which includes well-sealed coronal restoration to prevent leakage, reinfection of the root canal and prevent tooth fracture. Mandibular first premolars are difficult to treat due to variations in the root canal morphology. The incidence of mandibular first premolars with one canal is 54-82.1%, two canals is 11.2-34.27%, and three canals is 0-3%.


The aim of this case report was to present the successful endodontic treatment of a right mandibular first premolar with three canals using dental loupes, apex locator and modification of the root canal access opening. After a one-year follow-up, it was found that the treatment outcome was favorable. The teeth could function as normal with no abnormal clinical symptoms, and the healing of the periapical pathology could be seen from the radiographic examination.
