Objective:

To determine the use of toothpaste in Peruvian children under 12 years of age during the period 2019-2021.

Materials and methods:

Cross-sectional study where the records of the Demographic and Family Health Survey-ENDES (from 2019 to 2021) were used to collect information on oral health. The results were examined according to the study variables, and statistical analyses were performed.

Results:

A total of 98.89% (n = 81 668) of Peruvian children under 12 years of age used toothpaste in the period 2019-2021; however, its use decreased over the years, finding statistically significant differences. The use of fluoride toothpaste with a minimum of 1000 ppm increased over the years, finding statistically significant differences. In the multivariate analysis there was a positive association between the year 2020 and the use of fluoride toothpaste with a minimum of 1000 ppm (aPR = 1.04; 95% CI: 1.01-1.07; p = 0.004). A positive association was also found between the year 2021 and the use of fluoride toothpaste with a minimum of 1000 ppm (aPR = 1.12; 95% CI: 1.10-1.15; p < 0.001).

Conclusions:

There is an association between the use of toothpaste and year, natural region, area of residence, place of residence, altitude and age; in addition to association between the use of fluoride toothpaste with a minimum of 1000 ppm and year, natural region, area of residence, place of residence, wealth index and age.
