摘　　要：目的系统评价截冠术拔除下颌阻生智齿的效果。方法计算机检索Pub Med、Embase、Web of Science、CENTRAL、SIGLE、CNKI、CBM数据库中关于截冠术拔除下颌阻生智齿的文献,由2名评价者独立进行文献质量评价和资料提取后,采用RevMan5.1软件进行meta分析。结果共纳入4个研究,截冠术组401例和一次完全拔除组539例患牙,meta分析结果显示：下牙槽神经损伤、术后感染,干槽症、术后一周疼痛的相对危险度和95%可信区间分别是0.11（95%CI=0.03～0.36;P=0.000 3）,1.03（95%CI=0.54～1.98;P=0.93）,0.55（95%CI=0.28～1.05;P=0.07）,and 1.14（95%CI=0.57～2.30;P=0.71）。结论截冠术应用于下颌阻生智齿的拔除,可降低下牙槽神经损伤的风险,值得临床推广应用。Objective To evaluate the effect of coronectomy on removal of mandibular wisdom teeth. Methods The literatures were re- trieved with computer about coronectomy from PubMed, Embase,Web of Science,CENTRAL,SIGLE, CNKI and CBM. The data extraction and quality assessment were analyzed by two reviewers independently using software RevManS. 1. Results Four studies met our inclusion criteria with 401 teeth in Coronectomy group and 539 teeth in total removal group, meta analysis showed：The RR（eoronectomy vs. total re- moval） was 0. 11（95% CI=0.03 -0.36,P=0.0003）,1.03（95% CI=0.54-1.98,P=0.93）,0.55（95% CI=0.28-1.05,P= 0.07） ,and 1.14（95% CI =0.57 -2.30,P = 0.71 ） for inferior alveolar nerve injury,post-operativc infection,dry socket,and pain at 1 week after surgery,respectively. Conclusions Coronectomy appears superior in reducing inferior alveolar nerve damage and could be used in clinical practice for third molar extractions with high risk of nerve injury.
