Effect of various remineralizing agents on eroded enamel –an in vitro study

AIM: To assess the effect of CPP-ACP (Tooth mousse,GC INDIA) , CPP-ACPF(Tooth mousse plus,GC INDIA) and Arginine containing paste (Sensitive pro relief,COLGATE INDIA) remineralizing agents on enamel surface after erosive challenge.MATERIALS AND METHODS: Buccal and lingual enamel surfaces of the selected20 molar teeth were used, and embedded in acrylic resin and enamel surfaces wereground flat with Silicon carbide paper disc. Samples were assigned into 4 groups with10 samples each. Group1 was the control with no treatment, Group 2 of CPP-ACP,Tooth mousse, GC INDIA, Group 3 of CPP-ACPF, Tooth mousse plus, GC INDIAand Group 4 of Arginine containing paste( Sensitive pro relief, COLGATE INDIA).The specimens were then exposed to erosive challenge and treatment. The surfaceroughness’s of the samples were evaluated before and after erosive cycles using surfacecontact profilometer.RESULTS: There was no significant difference seen while comparing before and aftervalues for the groups. In intragroup comparison, significant difference for RA beforeand RA after values in all 4 groups were seen.Key words: Casein phosphopeptide-amorphous calcium phosphate–fluoride–dentin–erosion–arginine containing paste
