Secondary analysis of data on 41,330 children aged one to 11 from the Demographic and Family Health Survey (ENDES) carried out in 2018. The frequency of brushing and the use of toothpaste were reported according to the level of fluoride (no brushing, adequate, inadequate, did not show/did not use toothpaste, and illegible), according to socioeconomic and geographical variables. The evaluation showed that 7.8% of children did not brush their teeth; there were significant percentage differences (p <0.001) in the use of toothpaste with inadequate fluoride concentration between the extreme categories of the variables: age (12.3%), use of dental services (7.7%), educational level of the person responsible (20.4%), wealth index (17.8%), geographical domain (11.3%), and area of residence (9.1%). A considerable percentage of Peruvian children do not brush their teeth; in addition, a large number of children who brush use toothpastes with a fluoride content that has no preventive effect.
