Buffered 2 percent Lignocaine Vs Buffered 4 percent articaine in Mandibular Flap Surgery A Double Blind Split Mouth Trial

This double-blind, split-mouth randomized controlled trial is designed to compare the clinical efficacy of buffered 2 percent lignocaine and buffered 4 percent articaine in patients undergoing bilateral mandibular periodontal flap surgery. To enhance onset and comfort. A total of 16 patients ie 32 surgical sites will be enrolled. Each patient will receive both anaesthetics on contralateral sides in two appointments. The buffered solutions are prepared with sodium bicarbonate Clinical outcomes assessed include onset time, duration of anaesthesia, intraoperative pain VAS, need for reinjection, and adverse effects. Randomization and blinding of operator and patient will minimize bias, and all surgeries will be performed by the same periodontist. Statistical analysis will involve paired t-tests for continuous variables and chi-square tests for categorical data, with significance set at p < 0.05. The study aims to determine whether buffered articaine provides superior onset, duration, and patient comfort compared to buffered lignocaine, thereby guiding clinicians in optimal anaesthetic choice for mandibular periodontal surgeries.
