The term hemisection refers to the removal or separation of a root-with its accompanying crown portion-from a 2-rooted tooth, such as a mandibular molar. A hemisection is considered a conservative treatment option for mandibular molars that would otherwise require extraction. A hemisection of an affected tooth helps to preserve the tooth structure and alveolar bone and is more economical than other treatment options. Therefore, hemisection may be a suitable alternative to extraction and implant therapy and should be discussed with patients during their consideration of treatment options. This case report describes a hemisection procedure in which the grossly carious distal half of an endodontically treated mandibular left first molar was removed.
半切术是指将一颗双根牙（如下颌磨牙）的一个牙根及其相连的牙冠部分切除或分离。半切术被认为是下颌磨牙的一种保守治疗选择，否则这些磨牙可能需要拔除。对患牙进行半切术有助于保留牙齿结构和牙槽骨，并且比其他治疗选择更经济。因此，半切术可能是拔牙和种植治疗的合适替代方法，在患者考虑治疗方案时应与他们进行讨论。本病例报告描述了一种半切术，其中切除了经根管治疗的下颌左侧第一磨牙严重龋坏的远中半部分。
