Morphology evaluation of primary enamel exposed to antihistamine and fluoride dentifrice--an in vitro study.

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.
