Aim To describe a rare case of gemination involving a mandibular first premolar. Summary The complex morphology of geminated teeth renders their endodontic and periodontal management difficult. Root canal and periodontal treatments were performed on a geminated mandibular first premolar with three canals. Clinical examination showed two separated crowns with united roots. Radiographically, two distinct pulp chambers with two joined and a third independent canal were seen. Conventional root canal treatment resulted in complete healing of the apical lesion. However, the occurrence of a vertical fracture led to the extraction of the mesial segment. At the follow‐up visit, the distal segment was clinically healthy and continued to satisfy functional demands. Key learning points• Failure to diagnose the initial crack along a gemination groove resulted in further propagation and finally complete vertical fracture. • Owing to the abnormal morphology of the crown and the complexity of the root canal system in geminated teeth, treatment protocols require special attention. • For asymptomatic cases without aesthetic or orthodontic problems and without associated pathosis, routine review and careful maintenance are required.
