ENDODONTIC RETREATMENT IN A TOOTH WITH FURCATION PERFORATION USING MTA: CASE REPORT

Abstract

Endodontic retreatment in teeth with furcation perforation represents a significant clinical challenge due to the involvement of periodontal tissues and the risk of treatment failure. This study aims to report a clinical case of endodontic retreatment in a tooth with furcation perforation, emphasizing the use of Mineral Trioxide Aggregate (MTA) as the sealing material. A 55-year-old female patient presented with pain during mastication on tooth 36, which was diagnosed with furcation perforation. The treatment included crown removal, pulp chamber disinfection, photodynamic therapy, and sealing of the perforation with MTA. Clinical and radiographic follow-up over 12 months showed absence of symptoms, bone repair, and maintenance of masticatory function. The case confirms the effectiveness of MTA as a biocompatible and bioactive material capable of providing a hermetic seal and inducing tissue regeneration. It is concluded that treatment success is directly related to accurate diagnosis, proper technique, and the use of high-performance materials.
