Effect of Diclofenac Mouthwash on Postoperative Pain after Periodontal Surgery.

INTRODUCTION

Non-Steroidal AntiInflammatory Drugs (NSAIDs) are widely used drugs for the management of pain. Oral administration of NSAIDs has various adverse events like gastrointestinal alterations - nausea, dyspepsia and gastrointestinal bleeding, hepatotoxicity and blood dyscrasias. As orally given NSAIDs are associated with systemic side effects, it is preferred to alleviate pain and inflammation using topical medication. Thus, recently the focus has been on the development of topical administration of NSAIDs in the form of gels, toothpastes and rinses.

AIM: To determine if diclofenac mouthwash, would be a better alternative to its systemic administration post surgery, in terms of patient acceptance and to minimize the adverse effects of orally administered drug.

MATERIALS AND

METHODS

The study was designed as a single blinded, randomized, controlled clinical trial. Thirty chronic periodontitis patients scheduled for full mouth flap surgeries were randomized to receive either Diclofenac Mouthwash (MW) or Diclofenac Tablets (TB), post surgery. The MW group patients (15) were advised to rinse undiluted 15 ml solution for 30 secs, twice daily for three days. TB group (15) was advised to take 50 mg tablet twice daily for three days. A 10 point Visual Analog Scale (VAS) and Wong Baker Facial Rating Scale (FRS) was recorded to measure the pain perception by the patients. Gingival status was assessed by the Modified Gingival Index (MGI) at Baseline and seventh day. Data pertaining to pain perception were analysed using repeated measures of ANOVA (Analysis of Variance) with post-hoc LSD test.

RESULTS

Intra group comparisons showed a significant reduction in pain, post surgery. Inter group comparisons showed a significant reduction only in the MGI scores of MW group, when compared to TB group. Intergroup comparisons showed no significant reduction in pain scores between both the groups, stating that diclofenac mouthwash is as effective as oral administration.

CONCLUSION

Diclofenac mouthwash is a better alternative to the systemic administration post surgery, in terms of patient acceptance and to minimize the adverse effects of orally administrated drug.
