Keywords:8-hydroxyguanosine, Gingival crevicular fluid, Local drug delivery, Ocimum sanctum, Oxidative stress, Reactive oxygen species
Background: Various locally delivered agent are used as an adjunct to scaling and root planning (SRP). 8- Hydroxydeoxyguanosine (8-OHdG) is best documented biomarker of oxidative stress in periodontitis. Objective: To evaluate the efficacy of locally delivered Ocimum sanctum gel by assessing the levels of 8-OHdG in Gingival crevicular fluid (GCF) of smokers and nonsmokers with periodontitis. Material and Methods: The study included 50 patients divided into 3 groups, group I - periodontally healthy, group II- smokers with stage II periodontitis and group III- non-smokers with stage II periodontitis. Smokers and non-smokers with stage II periodontitis received the locally delivered 10% OS gel as an adjunct to SRP at the test site at baseline and after 1 week recall, while SRP alone at control site. Result: 8-OHdG GCF levels were analyzed with enzyme-linked immunosorbent assay (ELISA) at baseline, and 6-months follow up. Probing pocket depth (PPD) in test site significantly reduced to 2.75 ±0.64, 2.50 ±0.68 at 6 month after periodontal therapy in group 2 and 3 respectively. Similarly, clinical attachment level (CAL) in test site significantly reduced to 3.15 ±0.81, 2.85 ±0.93 at 6 month after periodontal therapy in group 2 and 3 respectively. Conclusion: The application of 10% Ocimum sanctum L. gel showed significant improvement in PPD, CAL and PI and GI and reduction in GCF 8-OHdG levels.
