Clinical efficiency of sustained release chlorhexidine in collagen membrane in the non surgical management of localized periodontitis

Abstract

Objective: This study aimed to evaluate the clinical efficiency of sustained release chlorhexidine in a collagen membrane as an adjunct to scaling and root planning in the non-surgical management of chronic localized periodontitis. Materials and Methods: A total of 20 subjects with chronic periodontitis and 5-8 mm pockets that bled on probing were recruited from the Department of Periodontology, Dr. D. Y. PATIL Dental College and Hospital, Navi Mumbai. The subjects were divided into two groups: the control group, which underwent scaling and root planning alone, and the test group, which received scaling and root planning plus the placement of a chlorhexidine-impregnated collagen chip. Clinical parameters such as probing depth, clinical attachment level, and gingival index were recorded at baseline and follow-up visits. Results: The test group, receiving sustained release chlorhexidine in the collagen membrane, demonstrated greater improvements in clinical parameters compared to the control group. Reductions in probing depth, gain in clinical attachment level, and improvement in gingival index were observed in both groups, with the test group showing more significant improvements. Conclusion: The use of sustained release chlorhexidine in a collagen membrane as an adjunct to scaling and root planning appears to enhance the clinical outcomes in the non-surgical management of chronic localized periodontitis. The sustained release delivery system may provide prolonged antimicrobial effects, leading to improved periodontal health. Further research with larger sample sizes is warranted to validate these findings and explore long-term effects.
