Practitioners need to know the normal and complex anatomy of the root canal system of individual teeth. Maxillary central incisors almost in all cases have one root and one root canal system. This case report describes a non-surgical endodontic treatment of a double-rooted maxillary central incisor using cone-beam computed tomography (CBCT). A fourteen-year-old male with spontaneous pain of the maxillary left incisor showed the presence of an extra root on the periapical radiograph. CBCT was used to assess the root canal details that lead to finding a narrow root in the mesial of the main root. Also, a periapical bone defect was detected. Nonsurgical treatment of tooth performed. At the 3-month follow-up, the tooth was functional and the lesion was healed. Therefore, practitioners should consider the presence of extra roots and canals during root canal treatment. CBCT imaging helps in detecting the exact location of the extra root.
从业者需要了解个别牙齿根管系统的正常和复杂解剖结构。上颌中切牙几乎在所有情况下都有一个牙根和一个根管系统。本病例报告描述了使用锥形束计算机断层扫描(CBCT)对一颗双根上颌中切牙进行的非手术根管治疗。一名14岁男性,上颌左中切牙自发疼痛,根尖片显示存在额外牙根。CBCT用于评估根管细节,从而发现主根近中存在一个狭窄牙根。此外,还检测到根尖骨缺损。对该牙齿进行了非手术治疗。在3个月的随访中,该牙齿功能正常,病变已愈合。因此,从业者在根管治疗期间应考虑额外牙根和根管的存在。CBCT成像有助于检测额外牙根的确切位置。
