title: Effect of remineralizing agents on surface microhardness of primary and permanent teeth after erosion.
abstract: OBJECTIVE
  The purposes of this study were to compare the susceptibility of human primary and permanent enamel to dental erosion caused by soft drinks and to compare in vitro the remineralization potential of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) paste, 1.23 percent acidulated phosphate fluoride (APF) gel, and iron supplement.
  
  
  METHODS
  Fifteen extracted primary and permanent teeth were used for sample preparation. Samples were randomly divided into three treatment groups: CPP-ACP paste, APF gel and iron supplement. The samples were subjected to a series of demineralization and remineralization cycles and were evaluated through surface microhardness. Statistical analysis was performed using one way ANOVA and unpaired t -tests.
  
  
  RESULTS
  After remineralization, all samples showed an increase in surface hardness, which was significantly higher with CPP-ACP paste.
  
  
  CONCLUSIONS
  CPP-ACP paste was more effective at preventing dental erosion than the other products.
