右侧下颌尖牙双根双根管临床报告及文献回顾

摘要

下颌尖牙一般为单根单根管,单根双根管少见,出现双根双管则更少见.现报道1例右侧下颌尖牙双根双根管.锥形束CT(Cone beam computed tomography,CBCT)能够全面地展示根管系统,尤其是在术前就能针对复杂根管、变异根管做出正确的诊断.通过CBCT等辅助手段,能够提高变异根管的发现率,对于指导根管治疗以及防止拔牙术中遗漏牙根具有一定的临床意义.%The mandibular canine usually has a single root with a single canal. It is rarely to see a mandibular ca-nine with two roots and two toot canals. A case of a patient who has a right mandibular canine with two roots and two root canals was reported.Cone beam computed tomography(CBCT)comprehensively demonstrated the root canal system and especially provided the information of canal varieties and complex canal before operation. CBCT can improve the discovery rate of canal varieties,guide root canal treatment and prevent missed roots in tooth extraction.
