截冠术拔除下颌阻生智齿的系统评价

摘要/Abstract

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PubMed、 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 = 0.0003), 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)。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。

Abstract: Objective　To evaluate the effect of coronectomy for removal of mandibular wisdom teeth. Methods　The literatures were retrieved 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 RevMan5.1. 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 (coronectomy vs. total removal) 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-operative infection, dry socket, and pain at 1 week after surgery, respectively. Conclusion　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.
