Abstract:
:The purpose of this study was to investigate the demineralization of dentin by measuring changes in the velocity of the sonic longitudinal waves transmitted through this substrate. One group of samples was immersed in demineralization solution for 10 min twice a day and then stored in artificial saliva. Two additional groups of samples were treated with a solution of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) paste or a placebo paste without CPP-ACP before demineralization and a control group was stored in artificial saliva. The sonic velocity of the demineralized specimens was found to decrease significantly over time. No significant increase in sonic velocity was observed in specimens treated with CPP-ACP, suggesting that CPP-ACP acted to prevent demineralization.
