Abstract : The study aims to compare the efficacy of 2%lidocaine & 4%articaine & evaluate pain perception during needle insertion by the conventional and alternative techniques of local anaesthesia. The present experimental study included 180 patients between the ages of 30 and 50 who did not have any systemic diseases requiring local anaesthesia for tooth extraction. Which were divided into two groups. In group, A conventional technique was used, while in group B alternative technique was applied to provide Local Anaesthesia. The groups were further subdivided, and 45 patients in each group received 2% Lignocaine while the rest 45 patients received 4% Articaine as an Anaesthetic drug. The pain of the patient was measured with the help of the Visual Analog Scale (VAS). The main pain score in the conventional group was 1.03±0.75 and was significantly more significant than the mean score in the alternative group was 0.26±0.44. The mean pain score for the Conventional Lignocaine subgroup was 1.33±0.79, the Conventional Articaine subgroup was 0.73±0.57, the Alternative Lignocaine subgroup was 0.40±0.49, and Alternative Articaine subgroup was 0.13±0.34. The mean pain score was significantly greater in the Lignocaine subgroup in comparison to the Articaine subgroup. The efficiency of the alternative technique in relieving pain was significantly more significant than the Conventional Technique, and the efficiency of4% of articaine in relieving pain was significantly more significant than the 2% Lignocaine.
