Effect of remineralizing agents on surface roughness of demineralized enamel

Enamel surface roughness affects its visual properties, plaque retention, abrasion and bond strength. The aim of this study was to determine surface roughness of enamel lesions treated with Casein Phosphopeptide-Amorphus Calcium Phosphate (CPP-ACP), fluoride and a combination of these two.
In this experimental study, 24 sound bovine anterior teeth were mounted in acrylic resin after decoronation. Then the samples were demineralized and divided into 4 groups: treatment with CPP-ACP, CPP-ACPF and fluoride mouthwash, fluoride mouthwash and control. After treatment, the surface roughness of each group was determined. Data were analyzed with one-way ANOVA, followed by Duncan post hoc tests (α = 0.05).
The surface roughness of the control group was significantly higher than that in other treatment groups (p value = 0.011).
The results showed that treatment with all the three remineralizing agents significantly reduced surface roughness.
