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.
