RETREATMENT OF THE MAXILLARY SECOND PREMOLAR WITH 4 ROOT CANALS

Abstract

A 37-year-old male patient reported that he had gone to three dentists who were unable to solve the problem, and was then referred to the specialist. Clinically, the patient presented pain on vertical percussion and palpation. Radiographically, the presence of filling material and anatomy suggesting an extra canal was observed. The root canal was unfilled with the Prodesign S rotary system from Easy file #25.08, followed by radiographic odontometry. The foraminal patency was performed with 30#01 files and the root canal was reprepared with rotary instrumentation (Prodesign Logic 2 System: 30#05 file, determining an enlargement and modeling appropriate to the anatomy of the canal. and the obturation of the root canal system was performed using the 30#05 single cone technique, associated with Bio C Sealer cement. It is concluded that variations in the configuration of the root canal are a great challenge for the endodontist during endodontic procedures.
