Abstract
Prevention of dental caries and remineralization of enamel subsurface
lesions before restorative intervention are a major challenge and goal of
modern dentistry.
Caries initiation is associated with demineralization of the subsurface
tooth enamel. Calcium and phosphate are lost from the subsurface
enamel, resulting in the formation of a subsurface lesion. At this early
stage, the caries lesion is reversible via a remineralization process
involving the diffusion of calcium and phosphorous ions into the
subsurface lesion to restore the lost tooth structure.
Aim of the study:
The aim of this study was to evaluate and compare:
1- The remineralizing effect of casein phosphopeptide – amorphous calcium
phosphate fluoride versus silver diamine fluoride on demineralized enamel
surfaces by qualitative evaluation:
b- Energy dispersive x-ray spectroscopy (EDX) for assessing mineral
content.
b- Environmental scanning electron microscope (ESEM).
2- The changes of demineralized surface hardness of treated enamel with
casine phosphopeptide – amorphous calcium phosphate fluoride and silver
diamine fluoride by-Quantitative evaluation : surface micro-hardness
examination
