Evaluation of efficacy of subgingival administration of 1% chlorhexidine gel as an adjunct to scaling and root planing in the treatment of chronic periodontitis - A clinical and microbiological study.

AIM: The aim of the present study was to evaluate the clinical and microbiological effects of subgingival administration of 1% chlorhexidine gel (Chlorhexamed® 1% gel) in patients with chronic periodontitis.

SETTINGS AND

DESIGN

The study was done in a parallel-arm design with a total of 30 patients with 60 sites suffering from chronic periodontitis. The patients were divided into control and experimental groups.

MATERIALS AND

METHODS

The clinical parameters recorded were plaque index, gingival index, modified sulcular bleeding index, probing pocket depth and relative attachment level at baseline, 1 month and 3 month. Microbiological colony-forming units were assessed for Porphyromonas gingivalis, Fusobacterium nucleatum and Tannerella forsythia at baseline, 1 week, 1 month and 3 months. The control group received scaling and root planing (SRP) after baseline evaluation; however, the experimental group received the application of Chlorhexamed® gel within 48 hours after SRP. Then, the values obtained were subjected to statistical analysis.

RESULTS

Both groups showed significant improvement from the baseline to 3 months in all clinical and microbiological parameters. The experimental group showed better improvement in all parameters.

CONCLUSION

The use of Chlorhexamed® gel has proven to be an efficacious adjunct with SRP in the treatment of chronic periodontitis.
