Introduction: Various chemotherapeutic agents can be administered subgingivally to enhance the efficacy of non-surgical therapy mechanical treatment. Chlorhexidine (CHX) is an effective antimicrobial agent and has been used as a topical antiseptic for over 30 years. The aim of the study was to evaluate and compare the clinical efficacy of various forms of local delivery of Chlorhexidine (CHX) i.e. 0.2% CHX irrigation, 1.5% CHX gel and 2.5mg biodegradable CHX chip as an adjunct to scaling and root planning in the management of Chronic Periodontitis.
Materials and Methods: 40 sites from patients with Chronic Periodontitis and probing depth 5 to 7 mm were randomly divided into 4 groups. Group I (10 Sites): scaling and root planing (SRP) + subgingival irrigation with 0.2% Chlorhexidine; Group II (10 Sites): SRP + subgingival application of 1.5% Chlorhexidine gel (Chlo-Site); Group III (10 Sites): SRP + intrapocket administration of Chlorhexidine chip (Periocol-CG); Group IV (10 Sites): scaling and root planing only (control group). Improvement in periodontal health was assessed by the gingival index of Loe and Silness and plaque was assessed using the Turesky et al. modification of Quigley Hein Index at baseline, 1 month and 3 months. Pocket probing depth and clinical attachment level were also measured using customized acrylic stents.
Results: Significant clinical improvement was seen in all the groups from baseline to 3 months. Subgingival irrigation with 0.2% CHX xdid not provide any additional benefit over SRP alone in the improvement of clinical indices. Adjunctive use of 1.5% xanthan based CHX gel and CHX chip along with conventional nonsurgical therapy provided clinically favorable results in terms of reduction of pocket probing depth and clinical attachment level than SRP alone.
Conclusion: Based on the findings, it was concluded that 1.5% CHX gel and CHX chip provide significant results as compared to SRP alone. Subgingival irrigation with 0.2% CHX provides similar clinical benefits as mechanical debridement alone.
