AbstractLocal anaesthesia has been widely used in the medical and dental field. It produces anaesthesia by inhibiting excitation of nerve endings or by blocking conduction in peripheral nerves. During single crown preparation, dentists use anaesthesia even for root canal treated teeth during cord packing for gingival retraction to achieve haemostasis and to minimize pain. 356 patients who had undergone treatment for single crown preparation were selected and their treatment details like vitality of tooth, type of LA agent used, site of administration were reviewed. Details were tabulated in the Excel sheet and SPSS importing was done. Chi square tests were done between age, gender, type of arch and vitality of tooth with local anaesthetic agent used and the site of local anaesthetic administration. 1:2,00,000 epi+lidocaine was the most administered LA agent in both vital and non vital teeth. Commonly used site was buccal vestibule. This study concluded that buccal vestibule was the most common site of LA administration in both vital and non vital teeth and there was no statistical significance in the local anaesthetic agent used or site of administration in different age groups or gender or type of arch(p>0.05).
