Enamel remineralization efficacy of three widely used remineralizing tooth pastes: An in-vitro study

Abstract

Background: With introduction of newer enamel remineralization products in the market, it becomes important to evaluate and compare their remineralization efficacy. Hence the objective of the study was to assess and compare the enamel remineralizing efficacy of Casein phosphopeptide amorphous calcium phosphate cream, Nano-hydroxyapatite containing paste and Xylitol containing paste on artificially induced enamel carious lesions using surface micro hardness analysis.Methods: In-vitro study was conducted using 50 enamel specimens, randomly allocated to 5 groups of 10 samples each after standardization of Surface micro hardness. Except Group 1, specimens were subjected to demineralization for 4 days at 370 C following remineralization with slurry of remineralizing agents; Tooth Mousse Plus, nano-HAP and Remin Pro.Specimens were subjected to pH cycling for 28 days followed by assessment of surface micro hardness (PISMH). Student’s paired t-test, One-way analysis of variance test (ANOVA) and post hoc Tukey test were used for statistical analysis.Results: The surface harness of Tooth Mousse plus (333.62±38.95VHN) and Remin Pro (342.24±27) groups were significantly higher than the sound enamel group, nanoHap group (275.97±67) and demineralized enamel group (p
