Evaluation of Self-assembling Peptides Versus Amorphous Calcium Phosphate in the Treatment of White Spot Lesions

"Intervention: Self-Assembling Peptide P11-4~Intervention Description:~Self-Assembling Peptide P11-4 (SAP P11-4) is a synthetic peptide designed to mimic natural enamel matrix proteins. It is applied to cleaned, etched enamel surfaces with white spot lesions. The peptide diffuses into the subsurface lesion and self-assembles into a 3D scaffold that promotes nucleation and growth of hydroxyapatite crystals. In this study, it is applied at baseline and re-applied after 3 months. The product used is Curodont™ Repair.~Intervention: Casein Phosphopeptide-Amorphous Calcium Phosphate (CPP-ACP)~Intervention Description:~CPP-ACP is a milk-derived peptide complex that stabilizes calcium and phosphate ions in an amorphous form. When applied to enamel surfaces, it delivers these ions to promote remineralization of white spot lesions. In this study, MI Varnish™ is used as the source of CPP-ACP. The varnish is stirred and applied as a thin, uniform layer to cleaned tooth surfaces at baseline and"
