Abstract

Background: Benefits of remineralizing agents in a wide variety of formulations have been proved beneficial in caries management. Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) nanocomplex has been recommended and used as remineralizing agent. Nano-hydroxyapatite (n-HAp) is one of the most biocompatible and bioactive material having wide range of application in dentistry, but does it excel better compared to CPP-ACP. Aims: To evaluate and compare the remineralizing efficiency of the paste containing hydroxyapatite and casein phosphopeptide-amorphous calcium phosphate. Settings and Design: The study was an in vitro single blinded study with lottery method of randomization approved by the Institutional Ethics Committee. Materials and methods: 30 non carious premolar teeth. The teeth were demineralized and divided into 2 groups and subjected to remineralization. The samples were analysed for surface hardness and mineral content. Statistical Analysis: Student t' test and repeated measures of ANOVA was applied. Results: Average hardness in Nano-hydroxyapatite group increased to 340 ± 31.70 SD and 426 ± 50.62 SD for 15 and 30 days respectively and that of (CPP-ACP), 355.83 ± 38.55 SD and 372.67 ± 53.63 SD. The change in the hardness values was not statistically significant with P value of 0.39 (P > 0.05). Calcium and Phosphorous levels increased in both the groups but was not significant. Conclusion: Both the agents used are effective in causing remineralization of enamel. Nano-hydroxyapatite is more effective as compared to Casein phosphopeptide-amorphous calcium phosphate, in increasing the Calcium and Phosphorus content of enamel, and this effect is more evident over a longer treatment period. Key Message: Remineralizing agents are a boon for caries management. With the advent of many formulations it is difficult to clinically select the agent. This study compares the remineralizing potential of Casein phosphopeptide-amorphous calcium phosphate nanocomplex and Nano-hydroxyapatite and found that both are effective as remineralizing agents.
