Effect of Different Biomimetic Materials on White Spot Lesions in Enamel

Effect of Different Biomimetic Materials on White Spot Lesions in Enamel

This study will be conducted to evaluate: 1- The remineralizing effect of different biomimetic materials (Zinc carbonate hydroxyapatite nanoparticles, Poly-amido amine (PAMAM) and bioactive glass nanoparticles) on white spot lesions in enamel. 2- The clinical efficacy of these agents on disappearance of these white spots.
