“T”型法和三段法在近中水平阻生牙拔除术中的比较

The Comparative Study of T-shape Method and Three Sections Method Applying in Extraction of Medial Level Impacted Mandibular Third Molars

目的:比较2种方法在下颌阻生第三磨牙拔除术中手术时间、术后并发症方面的不同,探讨其优缺点。方法:选取60例双侧基本对称下颌阻生第三磨牙患者,两侧用不同方法拔除阻生牙,记录2组手术时间、术中断根情况、术后并发症,采用SPSS17.0软件包对数据进行配对t检验。结果:"T"型组去远中部分时间、术后24h疼痛和肿胀小于三段组,有统计学差异(P<0.05)。结论:在下颌近中阻生牙拔除术中,"T"型法优于三段法。

Objective： To compare operating time and postoperative complications between two methods in the extraction of mandible impacted third molars.Methods： Sixty patients with bilateral symmetrical mandible impacted third molars were included in this study.One side of impacted tooth were extracted by using T-shape method,while the others were extracted by using three sections method.Operating time,root pruning situation,postoperative complications were recorded.SPSS17.0 software package was used and paired t-test was performed to analyze the data.Results： There were statistical differences of distal removing time,facial edema and pain of 24h postoperative between two methods（P0.05）.In the T-shape group,the time was shorter,edema and pain were milder.Conclusion： In the extraction of mandible medial impacted third molars,T-shape method is better than three sections method.
