Abstract: PURPOSE: To evaluate the clinical usefulness of 45 degree turbine drill in the extraction of lower horizontally impacted mandibular third molar. METHODS: Sixty-four patients with lower horizontally impacted mandibular third molar were randomly divided into 2 groups (n=32). The control group underwent extraction with the traditional method of triangular flap and high speed turbine drill, while in the experimental group, the impacted tooth was completely divided with triangular gingival cutting to pull out the third molars. The surgical time and postoperative complications were recorded and compared using SPSS 20.0 software package. RESULTS: The operation time of the experimental group was significantly shorter than that of the control group (P<0.05), pain, swelling, alveolalgia and limitation of mouth opening were significantly lower than the control group (P<0.05), postoperative bleeding was similar in 2 groups (P>0.05). CONCLUSIONS: Dividing the impacted teeth completely with triangular gingival cutting is an effective method for extraction of lower horizontally impacted mandibular third molar. It can shorten the operation time, lessen postoperative pain, swelling, gum tearing, alveolalgia and limitation of mouth opening; it is safe and reliable and worth of wide clinical application.
