Efficacy of Infrazygomatic Approach Combined with Anterior Middle Superior Alveolar Nerve Block versus Standard Technique for Scaling and Root Planing: A Randomised Clinical Trial

Introduction: A profound anaesthetic technique is essential for performing periodontal procedures with an effective onset and adequate duration of action. The infrazygomatic approach combined with the Anterior Middle Superior Alveolar (AMSA) nerve block may serve as a better alternative to the conventional AMSA technique alone in the maxillary region, as it helps minimise palatal mucosal blanching and improves the extent of anaesthesia. The present study was conducted to evaluate whether the add
