Efficacy of different remineralization agents on treating incipient enamel lesions of primary and permanent teeth

Abstract

Aims and Objectives: The aim of this study was to compare the in vitro efficacy of different remineralization (RM) agents on RM of artificial caries by evaluating the density, light reflection, and the crystal size of the newly formed mineral in primary and permanent teeth. Materials and Methods: Caries-free primary and permanent molars were divided into seven groups (n = 20) and treated with: G1 - Deionized water, G2 - Colgate Cavity Protection, G3 - Sensodyne Rapid Relief, G4 - GC MI Paste Plus, G5 - Clinpro Tooth Creme, G6 - Clinpro 5000, and G7 - Sensodyne Repair and Protect. Lesion depths were evaluated using laser fluorescence (DIAGNOdent), and polarized light microscopy (PLM), and the minerals were evaluated using X-ray diffractometry (XRD). Results: The highest decrease in laser fluorescence readings was observed in G6 for both primary and permanent teeth. No significant difference was observed between G2, G4, G5, and G6 in permanent teeth and G4 and G6 in primary teeth (P > 0.05). In PLM analyses, lesions depths were found to be lower in G6 compared to the other groups. No significant difference was observed between G2, G4, and G6 (P < 0.05). XRD evaluation showed that the newly formed mineral in G6 was denser and highly crystallized compared to the other groups. Conclusion: This in vitro study demonstrated that Clinpro 5000 is more efficient in remineralizing incipient enamel lesions compared to the other agents tested. © 2019 Journal of Conservative Dentistry.
