拔除阻生智齿中涡轮机法与凿骨劈冠法的比较研究

目的比较涡轮机去骨拔除法(试验组)与凿骨劈冠法(对照组)在拔除中位和低位阻生智齿时的优劣.方法100例(200颗中/低位阻生智齿)均采用自体左右对照,通过掷硬币随机抽样决定试验组和对照组.试验组采用涡轮机拔除法,对照组采用凿骨劈冠拔除法.对手术时间,以及术后疼痛、术后肿胀进行对比观察.结果对于低位阻生齿,涡轮机去骨拔除法手术时间短、术后疼痛及术后肿胀轻.对中位阻生智齿,涡轮机去骨拔除法的手术时间和术后疼痛及肿胀程度大于凿骨劈冠法.结论涡轮机去骨拔除法较凿骨劈冠法在拔除低位阻生齿时具有优势,凿骨劈冠法较涡轮机去骨拔除法在拔除中位阻生智齿时有优势.

Comparison of Extraction of Impacted Mandibular Wisdom Teeth with Using Methods of Turbine Drill and Dental Chisel

Objective To compare extraction of impacted mandibular wisdom teeth with using turbine drill and dental chisel.Methods One hundred patients with impacted mandibular wisdom teeth on both sides were randomly divided into test group and control group,the test group was extracted by means of turbine drill and the control group by dental chisel method. The operation time,postoperative swell and pain were recorded to assess the effects of the methods.Results In the extraction of low impacted teeth,the operation time by turbine drill was shorter,the days after operation and the swell and pain were slighter than those by dental chisel.In the extraction of middle impacted teeth,the results were contrary.Conclusion Turbine drill is superior to dental chisel in the extraction of low impacted mandibular wisdom teeth.The method of dental chisel is superior to turbine drill in the extraction of middle impacted mandibular wisdom teeth.
