Abstract

Objectives: To compare the effectiveness of bupivacaine with adrenaline with that of carbonated bupivacaine with adrenaline on pain, onset of anesthesia and duration of anesthesia following surgical removal of impacted mandibular third molar.

Study design: All the patients who underwent surgical removal of impacted mandibular third molar and who fulfilled our inclusion and exclusion criteria from 1st June 2013 to 30th June 2014 were included in our study. Patients who were diagnosed as having impacted mandibular third molar were randomly allocated to two groups namely group A (bupivacaine with adrenaline), group B (carbonated bupivacaine with adrenaline). Pain during deposition of local anesthetic, onset of anesthesia and duration of anesthesia were compared between the two groups. The collected data were subjected to statistical analysis by Chi Square test, Mann-Whitney U test.

Results and conclusion: The efficacy of carbonated bupivacaine with adrenaline is more compared with bupivacaine with adrenaline in decreasing pain on deposition of local anesthetic solution and in rapid onset of anesthesia. The duration of anesthesia for carbonated bupivacaine with adrenaline and bupivacaine with adrenaline had no significant difference. The use of carbonated bupivacaine with adrenaline will reduce the patient discomfort both intra-operatively and post-operatively.
