Comparative evaluation of remineralizing potential of commercially available agents MI paste, Remin pro, and Clinpro using Scanning Electron Microscope and Energy Dispersive X-ray: An in vitro study

BACKGROUND: According to recent approaches, the prevention of initial dental caries is achieved using certain noninvasive methods. One such method is the topical application of remineralizing agents. Various remineralizing products are commercially available, but their efficacy is uncertain. AIM: The aim of the study was to evaluate the remineralizing potential of MI, Reminpro, and Clinpro using scanning electron microscope (SEM) and energy dispersive X-ray (EDX). METHODOLOGY: Forty extracted human premolars were collected. The samples were decoronated and the crown portion was coated with nail varnish leaving behind a 3 mm × 3 mm window on the labial surface. The samples were soaked in demineralizing solution for 4 days to create an artificial lesion, followed by SEM-EDX analysis. The samples were then randomly divided into 4 groups Control, MI, Remin Pro, and Clinpro with ten samples each. The remineralizing agents were applied according to the group and subjected to pH cycling for 21 days which was followed by SEM-EDX analysis. Data obtained were statistically analyzed using SPSS IBM version 23 (ANOVA, post hoc-Tukey, and Paired-t-test). RESULTS: Ca and P were increased after remineralization in all groups. Between groups, the increase was more for ReminPro, followed by Clinpro and MI. CONCLUSION: In this study, the remineralizing potential of Remin Pro was effectively more, followed by Clinpro and MI.
