Effectiveness of different anesthetic methods for mandibular posterior teeth with symptomatic irreversible pulpitis: a systematic review and meta-analysis

摘要: ObjectiveThis systematic review aimed to assess the effectiveness of anesthetic methods for mandibular posterior teeth with symptomatic irreversible pulpitis, comparing to the inferior alveolar nerve block (IANB) by meta-analysis.Materials and methodsStudies were identified from Cochrane Library, Embase, Lilacs, PubMed, Scopus, and Web of Science databases up to May 2021. Randomized clinical trials comparing the anesthetic success rate of IANB and any other alternative anesthetic method were included. The quality of the selected studies was assessed by the Cochrane Risk of Bias 2.0 tool. Meta-analyses using Mantel–Haenszel method and random-effect models were performed to find the pooled estimates of risk ratio (RR) with 95% confidence interval (CI). The quality of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation approach.ResultsTwenty …
