Comparison Of Pain Intensity Of AMSA Injection With Conventional Syringe And WAND System For Maxillary Periodontal Surgery

Context:Periodontal procedures require injection of local anaesthetic solution to avoid patient discomfort. Multiple injections are required to anesthetise anterior maxilla in the region of premolars to incisors. Anterior middle superior alveolar nerve block is a single palatal injection technique which anesthetises facial and palatal gingiva. Aims: The aim of the study was to compare the pain severity of AMSA technique using a conventional syringe and WAND in periodontal flap surgery. Settings and Design: 20 adult patients with a diagnosis of moderate to chronic periodontitis with an indication to periodontal surgery in maxillary quadrants were enrolled for the study. AMSA block was administered using a computer assisted syringe (WAND) on one side of mouth and a conventional syringe on the other at two separate appointments spaced at least one week apart. This was a split- mouth randomized cross over study. The pain intensities with respect to both the techniques were assessed by VAS scores Statistical analysis used: Independent t – test was used to compare pain (VAS) during injection using conventional syringe & WAND system. Results: The mean value of VAS scores in conventional group was found to be greater than those obtained by WAND system. Conclusions: The AMSA technique delivered through WAND system is proven to be better compared to the conventional technique.
