Abstract
This study was carried out to compare between the effect non-invasive treatment modality using fluoride, Tri-Calcium Phosphate and nanohydroxyapatite based remineralizing agents versus micro-invasive treatment modality using resinous and resin modified glass ionomer based infiltrant materials on surface micro-hardness of incipient carious enamel lesions. Furthermore, the stability of these treatment options upon exposure to acidic challenge.
