During re-mineralization of white spot lesion, Will biomimetic self-assembling peptides improve the re-mineralizating effect of the post orthodontic white spot lesion compared to fluoride-based delivery systems?

Conservative dentistry no longer prefers the "drill and fill" concept and advocates reversal of lesions via remineralization. . Remineralization is the process of restoring minerals - again, in the form of mineral ions - to the hydroxyapatite latticework structure. It is three-dimensional, and the lost ions must be replaced with ions having the exact same shape, size and the same electrical charge as those lost from the lattice.

Fluoride and self-assembling peptides have been used as adjuncts to enhance remineralization.
