Evaluation of superoxide dismutase levels in local drug delivery system containing 0.2% curcumin strip as an adjunct to scaling and root planing in chronic periodontitis: A clinical and biochemical study.
OBJECTIVE
Curcumin has proven properties such as anti-inflammatory, antioxidant, antimicrobial, and it also accelerates wound healing. The purpose of this study was to investigate the level of superoxide dismutase (SOD) enzyme, in gingival crevicular fluid (GCF), and the impact of nonsurgical treatment on the antioxidant profile using 0.2% curcumin strip as local drug delivery.


METHODS
A total of twenty subjects of age 35-55 years and 15 subjects with chronic periodontitis, each with bilateral 5-6 mm probing pocket depth, were selected for this study. Healthy group consists of 5 sites in which no bleeding on probing, no pocket depth. Group I - It consists of 15 sites with chronic periodontitis, in which scaling and root planing (SRP) was done (control group). Group II - It consists of 15 sites, in which SRP followed by the placement of curcumin strip inside the pocket (SRP + curcumin strip) (test group). GCF collection was done preoperatively and postoperatively after 21 days. The SOD activity was assessed using enzyme-linked immunosorbent assay.


RESULTS
In this study, all the clinical parameters were significantly reduced in test and control sites. Further, SOD levels were significantly improved in test sites when compared with control sites.


CONCLUSIONS
Thus, the present study concluded that curcumin strip can be effectively used as an adjunct to SRP in treatment of chronic periodontitis and serves as antioxidant in subgingival environment.
