Stability of chemically available fluoride in Chilean toothpastes

Abstract: Although most of the toothpastes tested kept their original TSF content after 1 year of storage, some products evidenced an important reduction, which may compromise their anticaries efficacy. Reductions in TSF may be explained by an incorrect F salt-abrasive formulation.

“…The therapeutic efficacy of a toothpaste is based on the release of fluoride into the oral environment at the time of brushing; for this reason, its formula must provide SF. [19][20][21] In our study, only 53% of the samples had the minimum concentration needed to promote an anticaries effect (1,000 ppm).…”

“…The ion fluoride present in sodium fluoride (NaF), stannous fluoride (SnF 2 ), or amine fluoride (AmF) react with the calcium present in CaCO 3 abrasive, dramatically, decreasing the soluble fluoride concentration and resultant anti-caries effect. Despite this interaction is a well-known fact, NaF was detected in several CaCO 3 -based dentifrice formulations sold in Chile 32 and Uruguay, 34 raising questions regarding the amount of soluble fluoride present in the formulations. In addition to an increase in the amount of non-fluoridated dentifrices available in the market, there are also a wide range of formulations with low concentrations of fluoride which certainly affect their potential to control caries.…”

“…O flúor é a substância mais importante usada nos cremes dentais, para aumentar a eficácia de escovação mecânica e obter o controle da cárie dentária, através da manutenção do equilíbrio entre a perda e o ganho de minerais da superfície do dente, processo dinâmico conhecido como desmineralização x remineralização. Em muitos casos, o flúor é capaz de prevenir o desenvolvimento da lesão de cárie ou, quando o desafio cariogênico for muito alto, diminuir a velocidade de progressão da lesão 8,12 .…”

“…O primeiro libera o flúor por ionização quando em contato com a água, já o MFP, pela ação de fosfatases presentes na cavidade bucal. Outra diferença entre as duas formulações é que, enquanto o NaF utiliza a sílica como abrasivo, o MFP é associado ao carbonato de cálcio, o que torna essa formulação mais barata e, consequentemente, mais acessível a populações menos favorecidas economicamente, prevalecendo nas compras por licitações do Sistema Único de Saúde (SUS) e sendo distribuída à população pelos serviços públicos de saúde do Brasil [10][11][12][13] .…”
