牙科高速气涡轮切割手机与传统器械拔除下颌阻生第三磨牙的临床比较

目的：探讨牙科高速气涡轮切割手机配合阻生牙专用加长裂钻拔除下颌阻生牙的方法和效果。方法选择2013年5月—2014年3月期间于安徽省口腔医院口腔颌面外科门诊需要拔除下颌阻生第三磨牙患者共120例，随机分为两组，对照组采用传统劈骨分牙法，试验组采用牙科高速气涡轮切割手机配合阻生牙专用加长裂钻拔牙，通过术后复诊，评价术后肿胀、疼痛、张口受限等情况以及断根、下唇麻木等发生率。结果对对照组和试验组术后创口肿胀、疼痛、张口受限等情况进行比较，差异具有统计学意义。结论应用牙科高速气涡轮切割手机配合阻生牙专用加长裂钻拔除下颌第三阻生牙的效果较为理想，值得临床进一步研究和推广。

Clinical comparison between dental high speed air turbine cutting handpiece and traditional instruments in mandibular impacted teeth extraction

Objective To evaluate the effect of mandibular impacted teeth extraction with dental high speed air turbine cutting hand-piece and surgery bur.Methods This study included 120 patients from Anhui Stomatology Hospital whose third molar teeth were ex-tracted.These patients were randomly assigned into two groups:the experimental group and control group.The control group was treated using tradition chisel splint method,meanwhile the experimental group was treated by dental high speed air turbine cutting handpiece and the bur.The probability of dental root fracture and lower lip numbness,swelling,pain and hardship of opening mouth in the consul-tation after the surgery were evaluated.Results The comparison of the probability of dental root fracture and lower lip numbness,swell-ing,pain and hardship of opening mouth between two groups was made.There were significant differences in two methods.Conclusions Dental high speed air turbine cutting handpiece and surgery bur perform better in mandibular impacted teeth extraction,which is wor-thy to be promoted and studied in clinic treatment.
