In vitro efficiency of fl uoride-containing compounds on remineralization of carious enamel lesions under cyclic pH conditions
Fluoride-containing products are mainly used due to their anticariogenic effect upon dental enamel. Objective: The aim of the present study was to determine the effi ciency of three fl uorinated compounds when used on demineralized enamel. Method: A demineralized surface was obtained by means of exp...

| Resumo: | Fluoride-containing products are mainly used due to their anticariogenic effect upon dental enamel. Objective: The aim of the present study was to determine the effi ciency of three fl uorinated compounds when used on demineralized enamel. Method: A demineralized surface was obtained by means of exposing the enamel of 120 permanent third molars to a demineralizing solution for 96 hours. Molars were randomly divided into four groups in order to receive topical treatment with the following fl uorinated compounds: 1) silver ammonium fluoride, 2) difluorsilane, 3) acidulated phosphate fluoride and 4) a control group. All samples were immersed in a cyclic pH system (pH 4.4 to 7.0) and retrieved after 5, 10 and 15 days in order to be observed. Samples were examined under polarized light and Tholuet solution in a photomicroscope (Zeiss, Germany) in order to determine remineralization according to exhibited birefringence. Results: After 5 and 10 days, the group treated with silver ammonium fl uoride showed signifi cant difference with respect to other groups. Nevertheless, acidulated phosphate fluoride 10-day results remained equally unaltered at 15 days. Conclusions: The group treated with silver ammonium fluoride presented more signifi cant changes than groups treated with silver ammonium fl uoride, difl uorsilane as well as the control group. |
