Objective:To study the feasibility of extraction of impacted mandibular wisdom teeth using turbine drill.Methods:Fifty-one patients with impacted mandibular wisdom teeth on both sides were included.In each patient the two wisdom teeth were randomly divided into test and control groups,the tooth on one side was extracted by means of turbine drill and that on another side 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 deeply impacted teeth the operation time by turbine drill was shorter(P
