Amyloid‐Mediated Remineralization for the Prevention of White Spot Lesions in Orthodontic Treatments

Advanced Materials Interfaces, EarlyView.
This study introduces phase‐transitioned lysozyme (PTL) coatings that trigger layer‐by‐layer hydroxyapatite growth on enamel. The PTL‐induced mineral shield mimics natural enamel structure, providing robust acid resistance and mechanical protection. Acting as a sacrificial barrier, it prevents biofilm‐induced demineralization and enables self‐repair ...
