Root resection and hemisection is a well-documented treatment option for extending the life span of furcated molars. The aim of the present study was to retrospectively evaluate the long-term results of root resection and hemisection of 195 patients with up to 40 years of follow-up. Records of 195 patients who had undergone root resection or hemisection were reviewed. A minimum follow-up of 5 years was needed. A molar was recorded as a survival if it was still present and functional without any signs of discomfort, pain, or pathology from restorative, endodontic, and periodontal points of view. Ninety-eight patients were excluded for not accomplishing the minimum 5-year observation period. Of the 97 remaining patients, 5 teeth were lost during the first 5 years of treatment and 92 teeth survived the follow-up period, ranging from 5 to 40 years. The overall survival rate was 94.8%. When up to 40 years of follow-up data were analyzed, it was found that high survival rates can be obtained with root resection and hemisection. The results are satisfying when a proper case selection, endodontic treatment, restorative design, and good maintenance program are given. This treatment option should always be considered before every extraction and implant placement.
牙根切除术和半切术是一种有充分文献记载的延长分叉磨牙寿命的治疗选择。本研究的目的是回顾性评估195例患者进行牙根切除术和半切术长达40年的随访结果。对195例接受牙根切除术或半切术患者的记录进行了回顾。需要至少5年的随访。如果磨牙仍然存在且功能正常，从修复、牙髓和牙周角度没有任何不适、疼痛或病变迹象，则记录为存活。98例患者因未完成至少5年的观察期而被排除。在其余97例患者中，5颗牙齿在治疗的前5年中脱落，92颗牙齿在5至40年的随访期内存活。总体存活率为94.8%。当分析长达40年的随访数据时，发现牙根切除术和半切术可获得较高的存活率。当进行适当的病例选择、牙髓治疗、修复设计和良好的维护计划时，结果是令人满意的。在每次拔牙和种植体植入之前，都应始终考虑这种治疗选择。
