Comparative Evaluation of Sustained Release Collagen Device Containing 5% Metronidazole (Metrogene) along With and Without Scaling and Root Planing at Regular Intervals with Treatment of Chronic Periodontitis: A Case Control Study

BACKGROUND A short-term study was undertaken with an objective to demonstrate the therapeutic benefit resulting from the use of Metronidazole sponges combined with and without mechanical debridement to mechanical treatment alone in the treatment of periodontal pockets in chronic periodontitis. MATERIALS AND METHODS The study compared the plaque index, gingival index, sulcus bleeding index and probing pocket depth in twenty control sites that received superficial scaling and root planing without the local drug delivery with experimental site A (20 sites that received local drug delivery (5% metronidazole) without superficial scaling and root planing) and experimental site B (20 sites received superficial scaling, root planing and local drug delivery (5% metronidazole) at "0" day, 15(th) day and 30(th) day. RESULTS There was a significant reduction in plaque index, gingival index, sulcus bleeding index and probing pocket depth in both experimental sites A and B at different intervals from the baseline. CONCLUSION From the above conclusions, it can be suggested that a single subgingival application of 5% metronidazole in a collagen carrier can be effective, when associated with debridement in the treatment of adult periodontitis.
