Aim To assess the efficacy of a 0.07% cetylpyridinium chloride ( CPC ) mouth rinse in the control of plaque and gingival inflammation during a 6‐month period. Material and Methods Adult subjects with moderate gingivitis were selected [≥40% bleeding on marginal probing ( BOMP )]. After retrieving microbiological samples and evaluating the clinical parameters (plaque, BOMP and stain indexes), a professional prophylaxis was performed and subjects were randomly assigned to the test ( CPC mouth rinse) or to the placebo group. Subjects were re‐assessed after 3 and 6 months. Results A total of 67 patients (35 test, 32 placebo) were included in the analysis. At 6 months, intra‐group significant plaque reductions were observed in the test group (0.691, p < 0.001), but not in the placebo (0.181, p = 0.653). At 6 months, the mean BOMP values were lower in the test group ( p = 0.052). Changes between baseline and 6 months were significantly higher in the test group both for plaque ( p = 0.002) and BOMP ( p = 0.037) when compared with the placebo. A microbiological impact was observed in the test group, especially for Prevotella intermedia . Conclusion The evaluated 0.07% CPC ‐based mouth rinse, used three times per day adjunctively to mechanical tooth cleaning, prevents plaque accumulation and gingival inflammation, as compared to the placebo, for at least 6 months.
