Clinical study of modified Gow-Gates technique of inferior alveolar nerve block in impacted mandibular third molar extraction

Abstract

Abstract: PURPOSE: 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.
