Aims and Objectives:Harnessing Mother Nature's bountiful remedies for rejuvenation has been in vogue since time immemorial. Turmeric contains the polyphenol Curcumin in its rhizome. It produces reactive oxygen species (ROS) with visible light irradiation as photodynamic therapy (PDT) - which validates its use in the treatment of periodontitis. This study compares Curcumin and Curcumin PDT as an adjunct to conventional Scaling and Root Planing (SRP) with SRP alone in the treatment of patients with chronic periodontitis.Materials and Methods:Sixty sites in fifteen untreated chronic periodontitis patients were randomly assigned in a split mouth design for one of the treatment modalities; 1) Scaling and root planing (SRP) alone, (2) SRP + Curcumin application for 5 min, (3) SRP + Curcumin application for 5 min + irradiation with blue light emitting diode of wavelength 470 nm for 5 min. (Curcumin PDT) on 0 day.(4) SRP + Curcumin PDT on “0”, 7th and 21st day. The clinical parameters included plaque index (PI), bleeding on probing (BOP) measured by sulcus bleeding index (SBI), probing pocket depth (PPD), clinical attachment level (CAL) recorded at the baseline & 3rd month. The site with greatest probing pocket depth (PPD) was selected from each quadrant for bacterial sampling and culturing for Aggregatibacter actinomycetemcomitans (Aa) and other black pigment producing microorganisms (BPB) like Porphyromonas gingivalis & Prevotella intermedia.Conclusion:The present study showed that Curcumin photodynamic therapy is a valuable treatment modality adjunctive to conventional scaling and root planing over Curcumin application. Moreover, multiple adjunctive applications of photodynamic therapy are more beneficial than single application in reducing clinical & microbiological parameters.

. The study protocol was reviewed and approved by the Institutional Review board of Coorg Institute of Dental Sciences. The nature and purpose of the study and the recall protocol was explained to the subjects and a written consent was obtained before commencing the study. The sampling and method of collection of data was similar to previuos study done by same authors [16]. Inclusion Criteria for the study were patients who were diagnosed with either localized or generalized aggressive periodontitis aged between 18-35 years with at least one tooth with probing pocket depth ≥5 mm in each quadrant. Patients with periodontal treatment within the last 6 months, pregnancy, smoking, allergy to the dyes, systemic diseases, use of mouth rinses that could influence the outcome of therapy and ingestion of systemic antibiotics within the last 6 months were excluded from the study.

Background:The purpose of this study was to clinically evaluate the benefits of sub gingival chlorhexidine (CHX) varnish and biodegradable CHX chip application used as an adjunct to scaling and root planning (SRP) as combined therapy and also to compare the effect of combined therapy with SRP alone.Materials and Methods:Fifteen patients with at least three sites with a probing pocket depth (PPD) of 5-8 mm were considered. Following baseline evaluation, all three sites were subjected for SRP. After completing SRP, each site was randomly subjected for CHX varnish, CHX chip application and the 3rd site was left without any medication as a control. Clinical parameters such as sulcus bleeding index, plaque index, bleeding on probing (BOP), PPD, and clinical attachment level (CAL) were recorded at baseline, 1 month and 3 months post-operatively.Results:All three groups presented with an improvement in clinical parameters compared to baseline. The mean reduction in PPD was 2.4 mm in SRP sites, 2.5 mm in SRP + CHX varnish sites and 2.8 mm in SRP + CHX chip sites. The mean gain in CAL was 2.4 mm in SRP sites, 2.3 mm in SRP + CHX varnish sites and 2.8 mm SRP + CHX chip sites.Interpretation and Conclusion:The present study indicated that application of CHX varnish and placement of CHX chip as an adjunct to SRP produced a clinically significant reduction in the PPD, BOP and a gain in CAL at 30th day and 90th day from baseline when compared to SRP alone. The results though were not statistically significant.
