Abstract

Background and Objective: The biochemical effects of an over-the-counter (OTC) medication were studied, which consists of a single-tuft brush containing cetylpyridinium chloride as a bactericidal agent, dipotassium glycyrrhizate as an anti-inflammatory drug and allantoin as a promoter of cell proliferation and wound healing, for delivery to hardly brushed sites. Material and Methods: This randomized controlled double-blind study was performed in 61 subjects with chronic periodontitis in supportive periodontal therapy phase (test group: n = 27; placebo group: n = 28; dropout: n = 6). The OTC medication was self-applied twice a day for 12 wk to two molars with probing pocket depths of 4-6 mm. Biochemical indicators were evaluated at baseline and 12 wk using the suspension array system for eight cytokines and chemokines (interleukin [IL]-1β, IL-1ra, IL-4, IL-6, IL-8, IL-10, monocyte chemoattractant protein-1 and tumor necrosis factor [TNF]-α) in gingival crevicular fluid. Results: The levels of IL-1β, IL-6, IL-8 and TNF-α remained significantly lower in the test group compared to the placebo group. In the placebo group, when the probing pocket depth at baseline was 4 mm, IL-1β increased, particularly in the second molar tooth, and the greatest increase was seen when PPD at baseline was 5-6 mm. In the test group, IL-1β decreased markedly in cases with furcation involvement and low bleeding on probing at baseline. In both groups, IL-1β, IL-6 and TNF-α were closely correlated with each other. Conclusion: This OTC medication is biochemically effective for steady chronic periodontitis in the supportive periodontal therapy phase.
