To evaluate the efficacy of 2%, 4% Lignocaine, EMLA mixture and Precaine topical anaesthetic agents (with 1:1, 00,000 epinephrine) during the extraction of deciduous anterior tooth. Eighty patients with pre-shedding mobility of deciduous anterior tooth were divided randomly into four groups. Lignocaine, in amount of 2% and 4%, Precaine and EMLA topical anaesthetic agents were applied and the tooth was extracted. VAS has been used to assess the subjective pain while Wong-Baker faces scale and SEM pain scale have been used to record the objective pain to check the efficacy of these topical anaesthetic agents. SPSS ver.17 was used for statistical analysis. Group comparison was done by ANOVA (Fishers F test) and inter comparison was done by Tukeys t test. Based on the scoring criteria of VAS, SEM and Wong Bakers facial pain scales, Precaine had best scores followed by EMLA mixture, 4% Lignocaine, and then 2 % Lignocaine during extraction of primary anterior teeth with pre-shedding mobility. The efficacy of Precaine was superior compared to EMLA mixture followed by 4% lignocaine and 2% Lignocaine respectively.
