Endodontic treatment in a maxillary second molar with four root canals: A case report

Endodontic treatment is based on an understanding of the internal anatomy, which facilitates precise exploration canals. The present study aimed to report a clinical case referring endodontic upper left second molar, presenting mesiopalatal canal and communication with periodontal tissues in distal region pulp chamber, furcation region, due dental caries. 41-year-old patient did not any systemic health problems. was divided into three sessions. In first consultation, diagnosis pulpal necrosis obtained periapical area without changes normality, no pain vertical horizontal percussion, addition palpation at bottom sulcus around tooth. radiographic examination revealed vast suggestive caries tooth crown, so carious tissue removed chamber accessed. session, disinfectant penetration, working length determination, instrumentation root canals were performed Reciproc R25 system for mesiopalatal, mesiobuccal, distobuccal canals, R50 palatal canal. Bio-C Temp used as intracanal medication. After 18 days, filled apical gutta-percha cones Sealer, silicate-based cement. Then, sealed repair cement, Biodentine. floor light-curing glass ionomer, composite resin.
