INTRODUCTION
Fusion is a rare occurrence, and its definitive diagnosis is of prime importance for successful root canal treatment. This case report discusses the endodontic management of a supernumerary tooth fused with a right maxillary first molar by using cone-beam computed tomography (CBCT).
METHODS
Nonsurgical endodontic retreatment was performed on the supernumerary tooth. A communication between the maxillary first molar and the supernumerary tooth was repaired by using flowable resin.
RESULTS
After 1 year of follow-up, there were no clinical symptoms, and the maxillary first molar remained vital. Recall radiographs and CBCT showed satisfactory healing of the periapical pathosis.
CONCLUSIONS
Proper diagnosis and treatment planning for endodontic management of fused teeth by using CBCT can ensure predictable and successful results.
简介
融合是一种罕见的现象，对成功的根管治疗，其明确的诊断至关重要。本病例报告讨论了使用锥形束 CT（CBCT）对与右上颌第一磨牙融合的额外牙进行牙髓治疗的管理。
方法
对额外牙进行非手术根管再治疗。使用可流动树脂修复上颌第一磨牙和额外牙之间的连通。
结果
随访 1 年后，无临床症状，上颌第一磨牙仍有活力。复查 X 线片和 CBCT 显示根尖病变愈合良好。
结论
使用 CBCT 对融合牙进行牙髓治疗的正确诊断和治疗计划可以确保可预测和成功的结果。
