Abstract
Aim: To compare the remineralizing ability of between casein phosphopeptide amorphous calcium phosphate (CPP-ACP) and β-tricalcium phosphate (β-TCP) on dental erosion by soft drinks in human tooth enamel using atomic force microscope. Materials and methods: 40 extracted human anterior teeth which were randomly divided into two groups: CPPACP paste (GC Tooth Mousse) and β-TCP (ClinproTM Tooth Cream) paste demineralized in soft drink (Coca-Cola) for 2 min followed by remineralization by both pastes. Each sample was subjected to atomic force microscopy (AFM) for unexposed, demineralization and remineralization cycle for surface roughness determination. Results and statistical analysis: Both experimental groups of samples shows remineralization that is reduction in surface roughness which was higher with β-TCP paste. Statistical analysis was performed using Student unpaired t-test and ANOVA along with Tukey's post HOC analysis with p<0.01 in intra group comparison and not significant inter group comparison. Conclusion: The β-TCP mineralizing paste is effective on preventing dental erosion.

Dental erosion is a destructive process of losing tooth structure by acidic dissolution without bacterial involvement [1]
This study provides a clinical relevance on the importance of minimal invasive treatment on incipient carious lesion by remineralization
Summary
Dental erosion is a destructive process of losing tooth structure by acidic dissolution without bacterial involvement [1]. Continuous demineralization and remineralization takes place in oral environment. If this equilibrium disrupts, demineralization progresses deteriorating further tooth surfaces. This destructive process leads hypomineralized tooth surface to an irreversible loss and softening, thereby making it susceptible to fracture [2]. Carious lesion formation occurs by partial dissolution of hydroxyapatite of teeth. Erosion is the complete dissolution of hydroxyapatite layer by layer. Frequent consumption and availability of acidic beverages, carbonated drinks, fruit juices, wine and sports drinks causes a drop in plaque pH and increase the prevalence of dental erosion as an extrinsic factor
