title: A comparison of surface roughness after micro abrasion of enamel with and without using CPP-ACP: An in vitro study.
abstract: OBJECTIVE
  The aim of this study was to evaluate the surface roughness of enamel after micro abrasion with and without using remineralization agent, CPP-ACP (Casein Phosphopeptide-Amorphous Calcium Phosphate).
  
  
  METHODS
  Thirty freshly extracted anterior teeth were collected. The samples were randomly assigned to two study and one control group. Group A (n = 10) containing teeth in which only micro abrasion was done, Group B (n = 10) containing teeth in which CPP-ACP (G C Tooth Mousse) was applied after micro abrasion for a period of 30 days, once daily for three minutes and Group C (n = 10) in which no preparation was done and which acted as the control group. The samples were stored in artificial saliva and evaluated after 30 days, using surface profilometer. The results were tabulated and statistically analyzed.
  
  
  RESULTS
  According to the results of this study, a combination of the micro abrasion procedure and CPP-ACP application reduced the enamel surface roughness significantly, when compared to micro abrasion done alone.
  
  
  CONCLUSIONS
  Application of CPP-ACP after micro abrasion procedure significantly reduces the enamel surface roughness thereby decreasing the risk of caries.
