ABSTRACT

Introduction: Currently, there is a wide variety of toothpastes, which can be found in the national market, for different purposes. Among these are those used for the prevention of dental caries. These, contain fluoride in various concentrations as a therapeutic agent, and almost in their entirety, stipulate in their labels a content of 1,000 to 1,450 PPM of fluoride. Some studies have shown that the fluoride concentrations specified on the label, and what is found in the toothpaste do not match. Objective: To evaluate the concentration of total fluoride based on the Mexican Standard NMX-K-539-CNCP-2013, which establishes that toothpastes should not contain more than 1,500 PPM of fluoride. As well as determining if what is stated on the label of their packaging corresponds to the actual content of fluoride. Material and methods: The study was carried out, in triplicate, on 37 toothpastes. The method for determining the fluoride concentration was that of selective ion, described by the Pharmacopoeia of the United Mexican States. Results: The average concentration of this element was 1,262 PPM F- (± 170.7). Fifty nine percent of the dentifrices analyzed do not contain the amount stipulated in the label. Conclusions: The fluoride concentrations of dentifrices are within the Standard. The concentrations do not correspond to what is stipulated in the package.
