摘　　要：目的:比较2种T形切冠法在下颌阻生智牙拔除术中的临床效果。方法:将符合条件的120例患者随机纳入2组,分别采用横T切冠法(60例)和纵T切冠法(60例)拔除下颌阻生智牙。采用SPSS 22.0软件包比较2组拔牙时间、患者术中焦虑程度、术后疼痛及开口受限程度的差异。结果:横T组手术时间为(17.41±3.72)min,显著长于纵T组的(15.22±2.53)min(P<0.05),但术中焦虑程度较低(P<0.05)。2组术后疼痛评分及开口受限程度无显著差异(P>0.05)。结论:横T法有助于缓解术中焦虑,而纵T法利于缩短手术时间。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.
