The influence of prebrushing mouthwashes on plaque removal in children.

PURPOSE: The purpose of this study was to verify the influence of prebrushing mouthwashes on dental plaque removal in children.

METHODS

This study had a double-blind, randomized, controlled, crossover, 25-day experimental design, including 38 12- to 14-year-olds. Four solutions were used as prebrushing mouthwashes (Colgate Plax Magic, Listerine Cool Blue Agent, water and dye, and water) by each participant with seven days' washout. The plaque index was evaluated before and after tooth-brushing during the experimental period.

RESULTS

Intergroup comparisons showed no significant differences in plaque reduction among evaluated solutions (Friedman test, P>.78). Significantly more plaque was present before vs. after tooth-brushing (Wilcoxon rank test, P<.001), independent of the surface (buccal or lingual/palatal).

CONCLUSION

Use of prebrushing mouthwashes by children does not influence plaque removal by tooth-brushing.
