Remineralization is increasingly accepted as a viable non-invasive approach for restoring carious teeth, at least during the earlier stages of the caries process. According to the principles of minimal intervention dentistry, optimal non-invasive strategies are preferred for treatment of early enamel lesions. This study was designed to investigate the remineralising efficacy of casein phosphopeptide amorphous calcium phosphate on early enamel lesions using energy dispersive x-ray analysis for quantitative assessment and scanning electron microscope for morphological changes. It can be...
