| | Abstract | This in vitro study sought to evaluate the action of a pediatric medication with low pH and high acidity in primary enamel submitted (or not) to daily applications of fluoride dentifrice. For this study, 70 blocks of primary molars (n = 10 per subgroup) were analyzed using scanning electron microscopy. Six subgroups (two control and four experimental) were submitted to different treatments for 10 days. Microscopically, the enamel blocks of the subgroups that received medication and fluoride demonstrated the largest areas of partially or totally conditioned superficial enamel. The opposite was observed in the subgroups that were not exposed to fluoride; erosions in the internal enamel and in the transition zone between deep enamel and dentine showed superior percentiles. It was concluded that the medication modified the morphology of the primary enamel and that the use of fluoride was able to reduce the erosive effect of the formulation. | | Language | eng | | Pub Type(s) | Journal Article
