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.
Subjects: Children at age of development of dental fluorosis (up to 4 years) enrolled at day care centres from the city of Montes Claros (0.7 ppm F), Brazil.

The study design has two phases:

In the first phase, children are required to bring at the day care centres the tooth brush and the toothpaste used at home. There is no randomization, since the inclusion in either children's or regular toothpaste groups will be done based on each child's preference. The children are requested to tooth brush as the usual manner that the parent and the child do at home. Saliva expectorates are collected as the protocol described by Guha-Chowdhury et al. (1996). No instructions are provided in this phase or interventions by the researcher. Saliva expectorates are collected for further laboratory analysis. Toothpastes are collected for laboratory analysis.
In the second phase, children are required to toothbrush with other type of toothbrush following the same tooth brushing protocol. For example, children that previously used children's toothpaste will be provided a regular toothpaste, and vice-versa.

Parents are requested to answer a questionnaire regarding their children's tooth brushing habits and socioeconomic factors.

Laboratory analysis provides estimation of fluoride intake from tooth brushing with both toothpastes.

Analysis will base on dose of fluoride intake (mg F/Kg body weight/day) considering children's and regular toothpastes.
