Comparative Evaluation of Clinical Anaesthetic Efficacy of 15 % Lidocaine Spray and 20 % Benzocaine Gel during Removal of Arch Bars

BACKGROUND Application of arch bar is considered as a gold standard for intermaxillary fixation (IMF) in the management of mandibular fractures. Both the application and removal of arch bars can inflict pain for patients who require IMF. For removal of the arch bars, local anaesthesia (local infiltration or conduction block) is often indicated. The study aimed at comparing and validating the efficacy of topical lidocaine spray and benzocaine gel in patients undergoing removal of arch bars. infiltration The mean and standard deviation of the pain scores of Group A was 2.5 ± 0.70, Group B was 2.7 ± 0.67 and Control group was 5.5 ± 0.85. Both the test groups had a significant pain reduction when compared with the control group. Topical application of both 15 % lidocaine spray and 20 % benzocaine gel provided equally efficient analgesia and can be useful alternatives to conventional local anaesthetic infiltration during arch bar removal.
