ABSTRACT

OBJECTIVE:

In the present investigation, the anticariogenic effect of fluoride released by two products commonly applied in infants was evaluated.

METHODS:

Bovine sound enamel blocks were randomly allocated to each one of the treatment groups control (C), varnish (V) and diamine silver fluoride solution (D). The blocks were submitted to pH cycles in an oven at 37°C. Next, surface and cross-sectional microhardness were assessed to calculate the percentage loss of surface microhardness ( percentSML) and the mineral loss (deltaZ). The fluoride present in enamel was also determined.

RESULTS:

F/Px10-3 (ANOVA, p<0.05) in the 1st layer of enamel before pH-cycling were (C, V and D) 1.61ª; 21.59b and 3.98c. The percentSMH (Kruskal-Wallis, p<0.05) were -64.0ª, -45.2b and -53.1c. percentdeltaZ values (ANOVA, p<0.05) were -18.7ª, -7.7b and -17.3ª.

CONCLUSION:

The data suggested that the fluoride released by varnish showed greater interaction with sound enamel and provided less mineral loss when compared with silver diamine solution.
RESUMO

OBJETIVOS:

Este trabalho avaliou o efeito anticariogênico do flúor liberado por dois produtos comumente aplicados em crianças.

MÉTODOS:

Para isto, utilizaram-se blocos de esmalte de dentes bovinos distribuídos aleatoriamente em três grupos de tratamento controle (C), verniz fluoretado (V) e solução de diamino fluoreto de prata (D). Os blocos foram submetidos à ciclagem de pH a 37°C. Após, realizou-se o teste de microdureza de superfície (para o cálculo da por cento da perda de microdureza de superfície - por centoSML) e em secção longitudinal do esmalte ( por cento de alteração da área mineral - por centodeltaZ) e a determinação do flúor presente no esmalte (F/P x 10-3).

RESULTADOS:

As concentrações de flúor (ANOVA, p<0,05) na 1ª camada do esmalte, antes da ciclagem de pH, foram (C, V e D) 1,6ª; 21,6b e 4,0c. Os resultados de por centoSML (Kruskal-Wallis, p<0.05) foram -64,0ª, -45,2b e -53,1c. Os valores de por centodeltaZ (ANOVA, p<0.05) foram -18,7ª, -7,7b e -17,3ª.

CONCLUSÃO:

Os dados sugerem que o flúor liberado pelo verniz apresentou maior interação com o esmalte promovendo menor perda mineral quando comparado à solução de diamino de prata.
