Abstract | OBJECTIVE: METHODS: With Porphyromonas gingivalis, Prevotella intermedia and Fusobacterium nucleatum as the testing bacteria, the minimal inhibitory concentration (MIC) of cetylpyridinium chloride buccal tablets was determined using minute amount serial dilution test. The production of volatile sulfur compounds (VSCs) was measured using sulfide detector halimeter in the anaerobic bacteria culture at 4 and 8 h after addition of the tablets. The effect of the tablets in suppressing odor production by mouth-borne halitosis bacteria was assessed using cysteine challenge test in healthy volunteers, and the effectiveness was evaluated by measuring the reduction in VSCs production and the duration of the effect. RESULTS:
Cetylpyridinium chloride buccal tablets inhibited the growth of all the 3 bacteria. The tablets obviously inhibited VSCs production by the 3 bacteria with a effect similar to chlorhexidine. Compared with distilled water gargle, the buccal tablets significantly reduced cysteine-induced VSCs production level in the healthy volunteers (P<0.05), and the effect lasted for 230 min. CONCLUSION:
