Analgesic Efficacy of Curcuma longa (Curcumin) after Surgical Periodontal Therapy

To compare the analgesic efficacy of orally administered Curcuma longa (curcumin) and mefenamic acid (MA) after surgical periodontal therapy (SPT).

Seventy-six periodontitis patients were randomly divided into two groups. In the test group, patients received curcumin capsules (200 mg), and in the control group, patients received MA (500 mg). All patients underwent post-operative antibiotic therapy using 500 mg amoxicillin and 400 mg metronidazole for 7 days. Post-operative pain and discomfort were evaluated using the numerical rating scale (NRS) and verbal rating scale (VRS), respectively. Evaluation were performed after 24 (T1), 48 (T2), and 72 h (T3). Group comparisons were done using Student's t-test and the Mann-Whitney U-test. The level of statistical significance was established at p < 0.05.

All patients had stage 3/grade C periodontitis. The mean age of individuals in the test and control groups were 58.4 ± 7.3 and 57.2 ± 5.2 years, respectively. A family history of periodontal diseases was reported by 37.5% and 47.4% individuals in the test and control groups, respectively. In the test and control groups, the total mean duration of periodontal surgery was 168.2 ± 12.2 and 173.4 ± 10.7 min, respectively. There was no statistically significant difference in the mean NRS and VRS scores among patients in the test and control groups. In both groups, there was no statistically significant difference in the change in NRS scores at any time point.

Compared with MA, curcumin is ineffective for pain and discomfort management after SPT. The possibility of the results being biased due to lack of operator blinding cannot be overlooked.
