Abstract

RICOMINI FILHO, Antônio Pedro et al. Fluoride concentration in the top-selling Brazilian toothpastes purchased at different regions. Braz. Dent. J. [online]. 2012, vol.23, n.1, pp. 45-48. ISSN 0103-6440.  http://dx.doi.org/10.1590/S0103-64402012000100008.

To be relevant in terms of public health, widely-used toothpastes should have at least 1,000 ppm of soluble fluoride (F) concentration. Thus, the concentrations of total fluoride (TF) and total soluble fluoride (TSF) in the top-selling Brazilian toothpastes were evaluated. Samples (n=3) from toothpastes Colgate Anti-cáries^®, Colgate Total 12 Clean Mint^®, Colgate Tripla Ação Menta Original^®, Colgate Tripla Ação Menta Suave^® and Sorriso Dentes Brancos^® were obtained from each of the five regions of the country. The concentrations of TF and TSF were analyzed with ion-specific electrode calibrated with F standards and the results were expressed in ppm (µg F/g). All toothpastes showed TF concentration lower than 1,500 ppm F (1,388.2 ± 25.8 to 1,483.2 ± 98.2). The TSF values were higher than 1,000 ppm F and ranged from 1,035.5 ± 61.5 to 1,221.8 ± 35.2 for calcium carbonate/monofluorophosphate-based toothpastes and from 1,455.6 ± 12.5 to 1,543.0 ± 147.3 for silica/sodium fluoride-based toothpaste. Top-selling Brazilian toothpastes presented available fluoride concentration to control caries regardless of the region where they are purchased.
