Objetivo: Avaliar a efetividade do dentifrício de alta concentração de F na diminuição do processo de desmineralização do esmalte. Material e Métodos: Foram confeccionadas trinta amostras de esmalte bovino, as quais foram lixadas, polidas e obtida a microdureza (Knoop) inicial. As amostras foram distribuídas aleatoriamente em três grupos (G): DP - dentifrício sem F (placebo), DC - dentifrício convencional (1450 ppmF) e DAC - dentifrício de alta concentração (5000 ppmF). Para avaliar o processo dinâmico de desmineralização, cada grupo foi submetido a uma ciclagem de pH com solução desmineralizante e solução remineralizante. As amostras foram imersas durante 6 e 18h nas respectivamente soluções, durante cinco dias, a 37oC. O dentifrício correspondente a cada grupo foi diluído (1:3) e as amostras foram tratadas por 1 minuto, duas vezes ao dia. Após a ciclagem, foi realizada a análise da microdureza final e aplicado ANOVA e Tukey (p<0,05). Resultados: Os resultados mostraram que a microdureza final do DAC (247,4?39,4) comparada ao DC (211,9?53,5) mostrou diferença estatística (p?0,05). Conclusão: De acordo com os resultados, pode-se sugerir que o dentifrício de alta concentração de Flúor apresenta resultados superiores na inibição do processo de desmineralização do esmalte quando comparado ao dentifrício convencional

Mineral Loss

Laser and fluoride treatments have been shown to inhibit enamel demineralization in the laboratory. However, the intra-oral effects of this association have not been tested. This study assessed in situ the effect of a Transversely Excited Atmospheric CO2 laser (λ = 9.6 μm) and the use of pressure fluoridated dentifrice on enamel demineralization. During two 14-day phases, 17 volunteers wore palatal appliances containing human enamel slabs assigned to treatment groups, as follows: (1) non-fluoride dentifrice, (2) CO2 laser irradiation plus non-fluoride dentifrice, (3) fluoride dentifrice, and (4) CO2 laser irradiation plus fluoride dentifrice. A 20% sucrose solution was dripped onto the slabs 8 times per day. The specimens treated with laser and/or fluoridated dentifrice presented a significantly lower mineral loss when compared with those from the non-fluoride dentifrice group. The results suggested that CO2 laser treatment of enamel inhibits demineralization in the human mouth, being more effective when associated with fluoride.

Acid Challenge

This study evaluated the effect of high fluoride dentifrice on the bond strength of brackets after erosive challenge. Eighty-four enamel specimens were divided into seven groups(n=12): WN (distilled water/no acid challenge), W3C (distilled water/3 cycles of acid challenge), and W6C (distilled water/6 cycles of acid challenge) were not submitted to dentifrice treatment. Groups RF3C (regular fluoride dentifrice/3 cycles of acid challenge) and RF6C (regular fluoride dentifrice/6 cycles of acid challenge) were treated with dentifrices containing 1450 μg F−/g and HF3C (high fluoride dentifrice/3 cycles of acid challenge) and HF6C (high fluoride dentifrice/6 cycles of acid challenge) were with 5000 μg F−/g. Acid challenges were performed for seven days. After bond strength test, there was no significant difference among groups submitted to 3 cycles of acid challenge(P>0.05). Statistically significant difference was found between the regular and high fluoride dentifrices after 6 cycles of acid challenge (<0.05). Similar areas of adhesive remaining were found among control groups and among groups W6C, RF3C, RF6C, HF3C, and HF6C. The high fluoride dentifrice was able to prevent the reduction of bond strength values of brackets submitted to acid challenge. Clinical relevance: the high fluoride toothpaste prevents debonded brackets on erosive enamel.
