Comparison of Anaesthetic Efficiency of Warm and Conventional 2% Lignocaine Solution Using Insulin Syringe in Maxillary Primary Molars: A Randomised Controlled Clinical Trial

Abstract

Introduction: Pain on injection and incomplete                anaesthesia causes failure of the procedure and result in fear and anxiety in children. There are various methods of      reducing the pain during anaesthesia, one such method is warming or buffering the local anaesthetic agent prior to  administration of injection.

Aim of the study: To assess whether administration of    warm lignocaine solution using insulin syringe in maxillary primary molars would reduce pain during dental procedures.

Materials and Methods: Forty children between the age of   6-12 years who were undergoing dental treatment    participated in the study. A random crossover design was used. Each patient was randomly assigned to receive either warm or conventional 2% lignocaine on the first visit and the alternate local anaesthesia on the second visit. For subjective evaluation the Wong-Baker FACES pain rating scale were used.

Statistical Analysis: Wilcoxon signed-rank test and            Mann-Whitney U tests

Results: Pre-warmed lignocaine solution using insulin syringe resulted in less pain on injection (P=0.0004, P<0.001)

Conclusion: Prewarming the anaesthetic solution showed     a significant reduction in pain than normal solution associated with administration of injection during dental procedures        in children.
