| Popis: | This study aimed to analyze the fluoride concentrations in different dentifrices with antimicrobial and natural molecules marketed in Brazil. Thus, 12 dentifrices were selected to be analyzed for the concentration of total fluoride (TF), total soluble fluoride (TSF) and ionizable fluoride (IF). Two tubes of each brand were purchased at different locations. The samples were analyzed in duplicates using an ion-specific electrode and the concentrations were determined in μg F/g. The TF of all calcium carbonate dentifrices showed averages below 1500 ppm F. Regarding TSF, only one toothpaste had an average above 1000 ppm F−, while the IF values were almost 500 ppm F. In the analysis of fluoride in dentifrices which present silica as abrasive, the TF presented averages below 1500 ppm F, while the TSF all presented averages close to 1000 ppm F−, and the IF values varied from close to 500 ppm to more than 1000 ppm F. In dentifrices whose formulation contained calcium carbonate associated with silica or other formulations such as sodium bicarbonate, the TF, TSF, and IF values were all above 1000 ppm F. The evaluated dentifrices generally showed TF concentrations lower than those declared on the packaging; however, the TSF content remained close to 1000 ppm F. It can be concluded that the analyzed dentifrices with antimicrobial molecules showed values close to those suggested regarding anti-caries effect. |
