Title : Comparison of efficacy of lignocaine, ropivacaine and bupivacaine in pain control during extraction of mandibular posterior teeth

Posterior teeth extractions provide a challenge due to variations in anesthetics capacity and effects especially postoperatively. The aim of the study was to compare the efficacy of three anesthetic agents- lignocaine, bupivacaine and ropivacaine during extraction procedure of mandibular posterior teeth. 250 study participants were randomly divided into three groups: Group I (subjects under 2% Lignocaine (n=84); Group 2 (subjects under Bupivacaine (n=86) and Group 3 (subjects under Ropivacaine (n=80). Hemodynamic and anesthetic and analgesic parameters were recorded and statistically analyzed using ANOVA. Significant differences were observed between three anesthetic agents used pertaining to anesthesia and analgesic changes while no significant effects were observed when comparing the hemodynamic parameters. Ropivacaine provided best clinical outcome in terms of both anesthetic efficacy as well as post-operative analgesia following extraction of mandibular posterior teeth.
