Abstract

Comparison of therapeutic effects of 8 mg Dexamethasone Intramuscular Administered Pre-operatively vs. Post Operatively after the Surgical Extraction of Impacted Mandibular Third Molars. Materials & methods: 100 outpatients who underwent surgical removal of lower third molar were included and were broadly divided into two study groups: Group A: Administration of Pre-operatively Intramuscular 8 mg Dexamethasone, and Group B: Administration of Post-operatively Intramuscular 8 mg Dexamethasone. Patients were subjected to complete history taking including medical and dental examination as per proforma. Maximum interincisal opening was measured pre-operatively, 1st and 3rd day. Visual analogue scale was used to analyse the intensity of the pain (0-10). The results of the two groups were compared using t-test. Results: Among the patients of group A, mean mouth opening during preoperative period, postoperative 1st day and postoperative 3rd day was 48.1 mm, 35.3 mm and 46.5 mm respectively. Among the patients of group B, mean mouth opening during preoperative period, postoperative 1st day and postoperative 3rd day was 48.6 mm, 31.7 mm and 39.4 mm respectively. Significant better results were obtained in terms of mouth opening among patients of group A. Mean VAS among the patients of group A at preoperative time, postoperative 1st day and postoperative 3rd day was 0, 4.3 and 2.4 respectively. Mean VAS among the patients of group B at preoperative time, postoperative 1st day and postoperative 3rd day was 0, 4.1 and 2.1 respectively. Non-significant results were obtained while comparing the mean VAS at different time intervals. Conclusion: It was concluded from the study that superior post-operativetherapeutic effects are achieved by pre-emptive administration of 8 mg intramuscular injection of dexamethasone
