COMPARISON OF THE REMINERALIZATION POTENTIAL OF OYSTER SHELL POWDER, BAMBOO SALT AND CASEIN PHOSPHO-PEPTIDE AMORPHOUS CALCIUM PHOSPHATE (CPP-ACP) - AN INVITRO STUDY

Abstract

Aim: The aim of the study was to compare the remineralization potential of oyster shell powder, bamboo-salt and Casein Phospho-Peptide – Amorphous Calcium Phosphate (CPP-ACP). Materials and methods: Forty enamel slabs obtained from impacted third molars were subjected to Vickers microhardness test for evaluating the hardness and SEM-EDAX for elemental quantification of Calcium and Phosphate. Then, the samples were placed in demineralizing solution for 3 days followed by hardness test and SEM-EDAX analysis. They were divided into four Groups(n=10); Group 1- Oyster shell powder, Group 2- Bamboo salt, Group 3- CPP-ACP and Group 4- No treatment. The remineralizing agents were applied onto the enamel slabs for 3 minutes every 12 hours for seven days and left in artificial saliva until next application. After remineralization, hardness test and SEM-EDAX analysis were repeated. Statistical Analysis: One-way analysis of variance (ANOVA) and post-hoc Tukey’s test with a statistical significance level of p < 0.05. Results: Oyster shell powder showed statistically significant hardness and Calcium-Phosphate content compared to other groups. Conclusion Oyster shell powder had significant remineralizing potential followed by bamboo salt and CPP-ACP. These natural products showed promising remineralizing efficacy which is almost similar or even superior to the currently available proprietary remineralizing agents.
