It is essential to have an in-depth knowledge of root and root canal anatomy to prevent any iatrogenic errors. Many studies and case reports are present in the literature related to the anatomy of mandibular first molars, but most of them are on an extra number of roots and root canals. There are few studies related to a lower number of roots and root canals, but the occurrence of bilateral mandibular first and second molars with the presence of root fusion resulting in a single root is very rare. This case report presents the nonsurgical endodontic management of the left and right mandibular first molars with the presence of a single root confirmed using a CBCT and treated by placing an apical MTA plug followed by backfill using thermoplasticised gutta percha.
深入了解牙根和根管解剖结构对于防止任何医源性错误至关重要。文献中有许多关于下颌第一磨牙解剖结构的研究和病例报告，但其中大多数是关于额外数量的牙根和根管。关于牙根和根管数量较少的研究较少，而双侧下颌第一和第二磨牙出现根融合导致单一根的情况非常罕见。本病例报告介绍了使用CBCT确认存在单一根的左右下颌第一磨牙的非手术根管治疗管理，通过放置根尖MTA充填物，然后用热塑牙胶进行回填治疗。
