EFFICACY OF BENZYDAMINE HYDROCHLORIDE MOUTHWASH VERSUS DICLOFENAC TABLET IN POSTOPERATIVE PAIN AFTER PERIODONTAL SURGERY: A COMPARATIVE STUDY.

Abstract

Introduction: Benzydamine hydrochloride is an NSAID most often used in radiation induced oral mucositis. The indazole analogue benzydamine has physical,chemical, and pharmacological properties which differ from those of the aspirin-like NSAIDs. Benzydamine specifically act on the local mechanisms of inflammation, granuloma, and exudate.

Methodology: The study was a double-blinded, randomized, controlled clinical trial. A total of 30 chronic periodontitis patients reported to the dental hospital were selected for the study using a purposive sampling technique. Thirty chronic periodontitis patients scheduled for periodontal surgeries were randomized to receive either Benzydamine hydrochloride Mouthwash (MW) or Diclofenac Tablets (TB), post-surgery. The MW group patients were advised to rinse with undiluted 15 ml solution for 60 secs, 2-5 times daily for three days. TB group were asked to take 50 mg tablet twice daily for three days. A 10-point Visual Analog Scale (VAS) and Wong-Baker Facial Rating Scale (FRS) were recorded to measure the pain perception by the patients.Gingival status was assessed by the Modified Gingival Index (MGI) at baseline and seventh day.

Results: Intra-group comparison of pain values at day 1 and day 2 in both VAS and WONGBAKER scales demonstrated significance for the mouthwash group, suggesting more efficacy than the tablet group. Inter-group results showed statistical significance in both groups in relief of pain (p<0.05). Intra-group comparison results for both groups signified the superior efficacy of the mouthwash with p-values 0.010 and 0.005 at day 1 and day 2 for the Wong-Baker scale and with p-values 0.020 and 0.017 for VAS scale.

Conclusion: Inter-group comparison at baseline, day 1, day 2 showed significant results on day 1 and day 2, suggesting both the products were effective. Intra-group comparison of pain values in both VAS and WONG BAKER scales showed the significance of the mouthwash group, suggesting more efficacy than the tablet.
