Quantitative Analysis of Remineralization of Artificial Carious Lesions with Commercially Available Newer Remineralizing Agents Using SEM-EDX- In Vitro Study”

Abstract

Introduction: The basic principle of remineralization is by advocating a biological or non-invasive approach rather than the surgical approach for early enamel lesions. There are relatively newer products available for remineralization, latest being the resin-infiltration technique, commercially available as Icon. Aim: The aim of the study was to evaluate the remineralizing potential of Casein Phosphopeptide-Amorphous Calcium Phosphate (CPP-ACP), Vantej and Icon by the quantitative evaluation of mineral gain. Materials and Methods: Seventy eight maxillary premolars were decoronated at Cemento-Enamel Junction (CEJ) and then sectioned mesio-distally using diamond disc into two halves. Mineral content of the sound specimens were recorded using Energy Dispersive X-ray (EDAX) micro-analyser. The samples were then subjected to demineralization by using demineralizing solution. The samples were grouped (n=26) based on the remineralizing agent used, Group 1: Vantej, Group 2: CPP-ACP, Group 3: Icon. After the application of remineralizing agent, the mineral content was measured using EDAX. Results: After remineralization, there was a significant difference between the groups when calcium and phosphorous ratios (Ca:P) were compared, showing greater potential of remineralization for CPP-ACP followed by Vantej and Icon group. Conclusion: CPP-ACP performed better than Vantej and Icon in remineralizing the demineralized enamel.
