Aim: Chlorhexidine (CHX) is commonly used by dental practitioners and the public, due to its antimicrobial effects. The aim of this study was to Evaluate the efficacy of chlorhexidine chip as an adjunct to SRP in the treatment of chronic periodontitis.

Material and method: A study was conducted by the Department of Periodontics, Mansarovar Dental College and Hospital, Bhopal to evaluate the clinical and specific microbiological changes associated with chlorhexidine chip (DSI Sponge Perio, DSI Ltd, Ashdod, Israel) in chronic periodontitis patients. Twenty patients with chronic periodontitis and periodontal pockets > 4 mm. were randomly selected from the outpatient department. Patients were divided into two groups, each group contained ten patients. A 3 months simple randomized, clinical study was conducted comparing the effect of SRP with and without chlorhexidine chip in chronic periodontitis patient and the outcomes present in the probing depth (PD), gingival index (GI) and clinical attachment level (CAL) , AA and P.gingivalis were evaluated. Both clinical and microbiological recordings were carried out at baseline, 1 and 3 months post‑treatment.

Result: Periodontal parameters showed significant difference for Gingival index, Periodontal index, probing pocket depth, clinical attachment loss and mSBI at 3 months between Group A and Group B. P. gingivalis showed significant mean difference of 18.48000 at 3 months between groups at p=0.003. A. actinomycetemcomitans was found to be higher in Group 1 with a mean microbial count of 115.4000 X 103 while Group 2 had a mean of 81.2000 X 103 , which was significant at p=0.000.

Conclusion: Local drug delivery using chlorhexidine chip enhances the benefit of SRP in the treatment of chronic periodontitis.
