Abstract :

AIM: To evaluate the surface microhardness of enamel after the use of three different remineralizing dentrifices containing Casein Phosphopeptide–Amorphous Calcium Phosphate(CPP–ACP), Calcium Sucrose Phosphate(CSP) & Calcium Sodium Phosphosilicate(CSPS). MATERIALS & METHOD: Enamel specimens prepared from thirty freshly extracted anterior teeth were assigned to three groups of ten specimens each. After assessment of baseline microhardness values, demineralization was carried out with McInne’s solution and microhardness was reassessed. Remineralization for fifteen days was then carried out using CCP–ACP (I), CSP (II), CSPS(III) dentrifices and final readings were recorded. RESULTS: Data was analyzed using ANOVA and multiple comparisons done using Bonferroni method &Kruskal Wallis test showed that although all remineralization dentrifices produced increased microhardness values on demineralized enamel surfaces, CSP containing dentrifices gave higher microhardness values compared to CCP–ACP and CSPS CONCLUSION: The use of remineralizing agents increases microhardness of enamel in early carious lesions.
