ChildSmile has resulted in a dramatic reduction in dental caries in children; they are encouraged to brush their teeth daily at school with a fluoride toothpaste. In order to minimise cross-contamination, toothbrushes are stored in a spaced storage system. Symbols are displayed that allow each child to identify their own bush. In this study, 60 volunteers brushed their teeth twice each day for 7 days. Following brushing, the toothbrush was treated according to the following regimens: immersed in 1) 0.12% chlorhexidine gluconate, 2) 2% sodium hypochlorite, 3) a mouthrinse containing essential oils and alcohol (Listerine), 4) 50% white vinegar, 5) a tap water control, and 6) subjected to a dishwasher cycle. Following each disinfection regimen, the toothbrush was washed in water and stored in a vented container. White vinegar was the most effective method for disinfecting toothbrushes.
