IN VITRO STUDY OF PROTECTIVE EFFECT OF FLUORIDE VARNISHES AGAINST EROSION ON BOVINE ENAMEL
Abstract
Objective: To evaluate the protective effect of fluoride varnish on bovine enamel against erosive challenge. Methodology: Were obtained 12 enamel bovine blocks, in which half of the surface was applied the coatings following: Duraphat® (n=4), Fluorniz® (n=4) and Duofluorid XII® (n=4) at time 5 minutes. After this interval, the blocks were exposed to the cola soft drinks at the time of 15 and 30 minutes. Then, after washing, the varnish was removed with acetone P.A. and the blocks prepared and evaluated under scanning electron microscopy. Data were analyzed descriptively, considering the microstructural characteristics of the structure covered by adamantine varnish and that subject to the erosive challenge. Results: In the area exposed to the cola soft drinks, we evaluated two times, it became clear areas of dissolution of prismatic structure indicative of erosion. The enamel surface previously coated with different coatings showed no changes in structure. Conclusion: Under the experimental conditions of this study, fluoride varnishes analyzed showed a protective effect against the erosive challenge provided by the cola soda. DESCRIPTORS: Fluorides topical. Dental Erosion. Tooth Enamel.Downloads
