Reintervenção endodôntica em dente com canal em forma de C: Relato de caso

Abstract

Introduction: C-shaped canals appear as anatomical variations found mainly in lower second molars characterized by the presence of a ribbon-shaped channel. Due to its complexity and anatomical unpredictability, endodontic intervention or reintervention requires the professional to plan and conduct the treatment carefully. The aim of this study is to report a clinical case involving endodontic reintervention in a tooth whith C-shaped canal. Case Report: The patient was referred to the dental office for endodontic reintervention of tooth 37. The radiographic examination showed the presence of partial endodontic treatment and periodontal rarefaction extending from the distal bone margin to the peripexix. Mechanical chemical preparation was carried out and intracanal medication based on calcium hydroxide was used. After 30 days, the root canal system was filled. Follow-up were performed after 45 days, 75 days, 120 days and 17 months. Radiographic exams showed a reduction in periapical rerefaction with total bone formation after 17 months. Conclusion: After 17 months of follow-up, it was possible to observe bone repair associated with the absence of signs and symptoms.
