Abstract：Objective:To compare the clinical effects of high-speed air turbine drill and traditional chisel on removal of impacted mandible third molars. Methods:The clinical datas of the patients with 120 lower impacted mandible third molar were retrospectively analyzed.In witch high-speed air drill group(60) and chisel group(60)to be performed tooth extraction by high-speed air drill and traditional chisel osteotomy respectively. Then the duration of extraction and the intraoperative and postoperative complications were observed and recorded to assess the two methods.Results:The duration of extraction of drill group was shorter than chisel extraction group, which had statistical differences between the two groups(P＜0.05). The drill group had less postoperative complication such as ache, swelling, limited opening of mouth than those of the chisel extraction group(P＜0.05). Occurrence of the inferior alveolar nerve injury ,mandibular fracture, adjacent tooth damage and dry sock were lower than chisel extraction group (P＜0.05).Conclusions:High-speed air tutbine drill with its evident superiority to traditional chisel, when applied in the extraction of low impacted teeth, can efficiently cut down duration of extraction, reduce the incidence of the intraoperative and postoperative complication and is therefore recommendable in clinical practice.
