Efficacy of antimicrobial sprays for disinfection of children's toothbrushes: a randomized clinical trial

ABSTRACT

The objective of this study was to evaluate the efficacy of three spray antimicrobial solutions for the disinfection of childrenÆs toothbrushes. A 4-stage changeover system was used. The solutions studied were BrushtoxTM (Spray 1), CosmocilTM + basic formula (Spray 2), basic formula (Spray 3), and control û sterile water (Spray 4). Forty children used the solutions in all stages. In each stage, the children received a new toothbrush and performed a single 1-min brushing. Thereafter, the solutions were sprayed six times at different positions on the toothbrush bristles. After four hours, microbiologic culture of the toothbrushes was performed. BrushtoxTM, CosmocilTM + basic formula, and basic formula presented a similar effect on prevention of cariogenic biofilm formation which was better than basic formula alone or sterile water. BrushtoxTM showed the best antimicrobial efficacy.
