Background: Careful removal or inhibition of pathogenic micro organisms with locally delivered antimicrobials, along with scaling and root planning (SRP) is an effective approach for the management of chronic periodontitis. Aim: The evaluation efficacy of chlorhexidine chip as an adjunct to scaling and root planning for the treatment of chronic periodontitis patients. Materials and Methods: A total of 50 chronic periodontitis patients (aged 20-65 years) having pocket depth of ≥5 mm in molar teeth were selected and randomly divided into two groups: Group 1: Scaling and root planning (SRP), Group 2: SRP along with chlorhexidine chip. At the screening visit, complete history taking, periodontal examination and full-mouth supragingival scaling was carried out for each patient. At the baseline visit (on the 7th day), all clinical parameters were recorded at selected sites. All patients in both the groups received complete subgingival scaling and root planing. Then, in group B, 2.5 mg chlorhexidine gluconate (Periocol CG) was inserted at the selected site The clinical and microbial parameters were recorded at baseline, 1 and 3 months post treatment as above. Results: There was a significant difference in all the parameters in both the groups. Group B showed better results than group A. Conclusion: Local drug delivery using chlorhexidine chip enhances the benefit of SRP in the treatment of chronic periodontitis.
