To compare the clinical effect of Er:YAG laser and turbine handpiece in the removal of lower horizontally impacted wisdom teeth, and to evaluate the operation time, postoperative pain, facial swelling, degree of mouth opening limitation and complications.
From March 2020 to May 2022, forty patients with bilateral lower mandibular horizontally impacted wisdom teeth in the Department of Oral and Maxillofacial Surgery of Linyi People's Hospital were selected，and all bilateral wisdom teeth were partially bone buried. The bilateral wisdom teeth of each patient were removed by Er:YAG laser on one side and turbine handpiece on the other side, respectively. The patients were divided into experimental(laser) group and control(turbine handpiece) group according to the ways of bone removal on each side. The clinical effect of the two groups was compared after a week of follow-up. Statistical analysis was performed with SPSS 19.0 software package.
There was no significant difference between the two groups in operation time(P＞0.05). The incidence of postoperative pain, facial swelling, mouth opening limitation and complications in the experimental group were significantly lower than those in the control group(P＜0.05).
The operation time of extraction with Er:YAG laser is similar to that with turbine handpiece, but laser can reduce postoperative reaction and the incidence of complications, which is easy to be accepted by patients and worthy of wide application.
比较铒激光与涡轮机在拔除下颌低位水平阻生智齿中的临床效果，评估手术时间、术后疼痛、面部肿胀、张口受限程度及并发症情况。
选取2020年3月至2022年5月临沂市人民医院口腔颌面外科40例双侧下颌水平阻生智齿患者，所有双侧智齿均部分骨埋伏。每位患者双侧智齿分别采用铒激光和涡轮机拔除，根据每侧的去骨方式将患者分为实验组（激光组）和对照组（涡轮机组）。随访1周后比较两组的临床效果。采用SPSS 19.0软件包进行统计学分析。
两组手术时间差异无统计学意义（P＞0.05）。实验组术后疼痛、面部肿胀、张口受限及并发症发生率均显著低于对照组（P＜0.05）。
铒激光拔牙手术时间与涡轮机相似，但激光可减轻术后反应及并发症发生率，易被患者接受，值得广泛应用。
