Introduction:

Various studies have shown that parents still do not have sufficient knowledge about the use of toothpastes that their children should consume. Many of them do not know from what age to start using toothpastes, the exact amount to be placed on the brush and especially how often they should be brushed.

To associate the level of knowledge of parents about the use of toothpastes with the characteristics associated with the estimated intake of fluoride in children between 6 months to 8 years of Metropolitan Lima and Callao.

Materials and methods:

An observational, descriptive, and crosssectional study. The questionnaire was carried out on 264 parents residing in Metropolitan Lima and Callao during the months of July to September 2020. The absolute and relative frequencies were calculated. For the bivariate analysis, the Chi-square test of the level of statistical significance was used was 0.05.

Results:

It is observed that 52.94% of the fathers, as well as 60.41% of the mothers present a medium level of knowledge about the use of fluoride toothpastes.

In addition, it was found that 56.25% of parents who stated that their children do not rinse with water after brushing have a high level of knowledge about the use of fluoride toothpastes.

Conclusion:

It was found that the 57.58% of parents had a median level of knowledge about the use of fluoride toothpastes. An association was found between the level of knowledge about the use of fluoride toothpastes and the characteristics associated with the estimated fluoride intake.
