Abstract

INTRODUCTION: The purpose of this prospective, randomized clinical trial was to evaluate the anesthetic efficacy of the Gow-Gates nerve block (GGNB), the inferior alveolar nerve block (IANB), and their combination for mandibular molars in patients with symptomatic irreversible pulpitis. METHODS: One hundred fifty patients diagnosed with symptomatic irreversible pulpitis of a mandibular molar were selected. The patients randomly received 2 GGNB injections, 2 IANB injections, or 1 GGNB injection plus 1 IANB injection of 1.8 mL 2 lidocaine with 1:80,000 epinephrine. Access cavity preparation was initiated 15 minutes after injections. Lip numbness was a requisite for all of the patients. Success was specified as no or mild pain on the basis of Heft-Parker visual analog scale recordings during access cavity preparation or initial instrumentation. Data were analyzed with the chi-square, Kruskal-Wallis, and analysis of variance tests. RESULTS: The success rates of anesthesia were 40, 44, and 70 for the GGNB, IANB, and GGNB + IANB groups, respectively. There was no statistically significant difference in the success rate of anesthesia between the GGNB and IANB groups (P > .05). The anesthesia success rate for the GGNB + IANB group was significantly different from those of the GGNB and IANB groups (P < .05). CONCLUSIONS: A combination of GGNB and IANB could improve the efficacy of anesthesia in mandibular molars with symptomatic irreversible pulpitis, but it would still require supplemental anesthesia. Further research may be needed to confirm the results of this study.
