title: [Clinical study of modified Gow-Gates technique of inferior alveolar nerve block in impacted mandibular third molar extraction].
abstract: OBJECTIVE
  To introduce a minimally invasive and more effective technique of inferior alveolar nerve block.
  
  
  METHODS
  Two hundred and six patients who needed extraction of the impacted mandibular third molar were divided randomly into 2 groups: the experimental group (105 cases) with modified Gow-Gates technique (modified Gow-Gates group) and the control group (101 cases) with Halstead technique (Halstead group). The anesthetic success rates, effects and complications were recorded and analyzed with SPSS17.0 software package.
  
  
  RESULTS
  The anesthetic success rate was 97.15% in modified Gow-Gates group and 89.10% in Halstead group with significant difference between the 2 groups (P=0.038<0.05); In comparing the anesthesia grade, the ration of grade A and B accounted for 90.48% in modified Gow-Gates group and 87.13% in Halstead group (P=0.446>0.05). Modified Gow-Gates group had much fewer of complications than Halstead group (P=0.014<0.05).
  
  
  CONCLUSIONS
  Modified Gow-Gates technique is a minimally invasive and more effective technique for inferior alveolar nerve block anesthesia. Supported by Science and Technology Planning Project of Yueqing City (2014y027).
