RESUMO
PURPOSE: To determine the impact of COVID-19 pandemic on use of toothpaste in Peruvian children. METHODS: A national database of Peruvian children from 0 to 11 years old was used to develop a cross-sectional study, with a final sample of 51, 013 subjects. Data were obtained of results of the Demographic and Family Health Survey (ENDES); the questionnaire was self-reported. The use of toothpaste and fluoride concentration in toothpaste were dependent variables, and for the independent variable, the year was considered; in addition, other covariates were included. The statistical analyses applied were descriptive, bivariate, and multivariate tests. RESULTS: Use of toothpaste was 98.99% (n = 50,134), while fluoride toothpaste with < 1000 ppm was used by 77.29% (n = 27,366). For bivariate analysis, use of toothpaste was associated with place and area of residence, altitude, natural region, and age; for use of fluoride toothpaste with minimum 1000 ppm, there was an association with place and area of residence, natural region, wealth index, and age. In a multivariate manner, year only presented a positive association with use of fluoride toothpaste < 1000 ppm (RPa:1.04; 95%CI 1.01-1.07). CONCLUSIONS: Year 2020 of COVID-19 pandemic had a positive impact on the use of < 1000 ppm fluoride toothpaste in Peruvian children.
