Surface roughness assessment with fluoride varnish application: An in vitro study

Background: The cause of cavities is initially due to roughness on the tooth surface, requiring fluoride varnish prevent caries, as applies a compound surface. Fluoride reacts with enamel surface form calcium and fluorapatite, thus making more resistant demineralization damage. Purpose: This study aims compare surfaces among three varnishes under acidic conditions. Methods: research method uses materials: sodium 5% + tricalcium phosphate, fluoride, casein phosphopeptide-amorphous phosphate 2%. Samples 81 teeth were divided into groups (Group 1 without application, Group 2 application pH 3, 3 5). tested before after using scanning electron microscope tests. Results: results showed significant difference in mean anterior deciduous varnish. comparisons 5 very (p-value 0.000). comparison each group administration no (pH p-value 0.074 0.196). appear be rougher an all-acid solution. Conclusion: There primary being given low immersion for 24 hours.
