Abstract

Abstract: PURPOSE: To compare the clinical efficiency of two types of T-shaped coronectomy applied in extraction of impacted mandibular third molars.METHODS: One hundred and twenty patients meeting with the criteria were randomly divided into 2 groups. Two types of T-shaped coronectomy were applied in extraction of impacted mandibular third molars. Indexes including operation time, intraoperative anxiety, postoperative pain and limitation of mouth opening were recorded and analyzed with SPSS 22.0 software package. RESULTS: Patients with transverse method experienced more time in operation [(17.41±3.72) vs (15.22±2.53) min], with less intraoperative anxiety (P<0.05). There was no significant difference in postoperative pain and limitation of mouth opening(P>0.05) between two methods. CONCLUSIONS: Transverse T-shaped method can alleviate intraoperative anxiety, while longitudinal method is more conducive to shortening operation time.
