Brief Summary

There are controversial data about fluoride intake by children when tooth brushing with children's or regular toothpastes. However, a study have showed that children were exposed to a dose of 0.051 mg F/Kg/day and 0.046 mg F/kg/day by tooth brushing with children's and and regular toothpaste, respectively. Fluorides doses were too close and is questioned if there is a real clinical relevance in terms of risk of dental fluorosis. It is important to evaluate if children's toothpastes does really represent a risk of fluoride intake when compared to the regular toothpastes in terms of risk of dental fluorosis. The hypothesis is that both children's and regular toothpastes can represente risks of development of dental fluorosis and can represent similar fluoride exposure by children.
