Introduction. The most widely used method for applying fluoride (F-)topically is the fluoridated toothpaste. Its early use in large quantities is a risk factor for dental fluorosis.
Objective: to determine the actual concentration of F-in toothpastes sold in the Mexican market.
Material and methods. Sixty-five different commercial toothpastes were analysed using the F-ion-specific electrode technique.
Results. The range of the F-content was from 0 to 2 053 ppm. Of them, 16.92% were toothpastes for infant use (range= 0-1153 ppmF-). Mexican toothpastes had a mean of 879 ± 599.2 ppmF-and imported toothpastes have a mean of 619.7 ppmF-; 54.5% of the infantile toothpastes presented F-concentrations above 730 ppm and in 40% of the analyzed products, annotation on F-content was found. Conclusions. Our results showed a wide variation in F-concentration and suggest the need to implement policies to regulate the F-concentration in these products. It is important that all the manufactured dentifrices show in the label and package the total F-content of the product and the recommended doses will be printed, in order to prevent dental fluorosis.
