摘　　要：目的探究牙半切除术联合后续修复在下颌后磨牙的临床应用。方法选取2017年12月至2019年12月本院牙科收治的30例根管治疗无效但具有保留价值下颌后磨牙患者进行研究。患者进行牙半切除术治疗及后续修复。观察治疗前后牙周情况,治疗7 d、14 d、28 d患牙情况、术后疼痛反应、肿胀度。结果治疗后牙周探诊深度低于治疗前,差异显著(P <0.05)。治疗7 d患牙成功率96.67%(29/30)、14 d成功率90.00%(27/30)、28 d成功率83.33%(25/30),三组比较无显差异(P> 0.05)。治疗28d术后疼痛0级比率高于治疗7 d、14 d,Ⅰ级和Ⅲ级低于治疗7 d、14 d;治疗14 d术后疼痛0级比率高于治疗7 d,Ⅰ级和Ⅲ级低于治疗7 d,差异显著(P <0.05)。治疗28 d VAS得分低于治疗7 d、14 d;治疗14 d视觉模拟评分(VAS)得分低于治疗7 d,差异显著(P <0.05)。结论牙半切除术联合后续修复对根管治疗无效但具有保留价值下颌后磨牙可有效减少牙周探诊深度,提高成功率,改善术后疼痛及肿胀度。Objective To explore the clinical application of semi resection combined with subsequent restoration in mandibular posterior molars. Methods Between December 2017 and December 2019, 30 patients with failed mandibular posterior molars to ineffective root canal treatment but of preserved value who were treated in our department of dentistry were enrolled for hemisection and subsequent repair. The pre-and post-operative periodontal conditions before and after treatment, the affected teeth on 7 d, 14 d, and 28 d,postoperative pain response, and swelling were observed. Results After treatment, the probing depth was lower than before treatment(P < 0.05). The success rate of treatment on the 7 th day was 96.67%(29/30), the success rate on the 14 th day was 90.00%(27/30),and the success rate on the 28 th day was 83.33%(25/30), but there was no significant difference between the three groups(P > 0.05).After 28 days of treatment, the rate of pain level 0 was higher than that of 7 days and 14 days, and the rate of levels Ⅰ and Ⅲ was lower than that of 7 days and 14 days(P < 0.05). The VAS score at 28 d was lower than that at 7 d and 14 d;the visual analogue score(VAS)at14 d was lower than that at 7 d(P < 0.05). Conclusions Hemisection combined with subsequent repair can effectively reduce the probing depth, improve the success rate, and improve postoperative pain and swelling in failed mandibular posterior molars to root canal treatment with preserved value.
