涡轮钻法与骨凿法拔除下颌阻生齿的临床观察

目的比较涡轮钻法与骨凿法拔除下颌近中阻生齿的临床疗效。方法选取我科2010年1月—2011年12月要求拔除下颌阻生齿124例患者,共148颗患牙,随机分为骨凿法组62例74颗患牙,涡轮钻组62例74颗患牙。比较两种方法拔除所需的时间、拔除后疼痛的程度、肿胀的程度、张口受限度临牙损伤、下颌关节疼痛等情况。结果两种方法拔除的术后反应有显著性差异（P〈0.05）。结论高速涡轮钻拔除下颌阻生齿较传统骨凿法手术时间短,术后反应轻。

Comparison of high-speed turbine drill and osteotome in mandible impacted tooth extraction

Objective To compare the clinical effect of high-speed turbine drill and osteotome in mandible impacted tooth extraction.Methods 148 mandible impacted teeth in 124 patients were randomly assigned to two groups：One group（containing 74 teeth） was extracted by high-speed turbine drill and the other group（containing 74 teeth）was extracted by traditional chisel.Then the clinical reaction including duration of extraction,the level of aches,swell and opening of mouth,incidence of adjacent dent trauma and low jaw pain between the two methods were evaluated.Results There were significant differences in postoperation reaction between two groups（P0.05）.Conclusion High-speed turbine drill applied in extraction of impacted teeth is better than the method of osteotome with little duration and fewer postoperation reaction.
