A Novel Strategy for Caries Management: Constructing an Antibiofouling and Mineralizing Dual-Bioactive Tooth Surface

biofilm on the tooth surface. It also protects teeth from demineralization in acidic environments, and induces self-healing regeneration in the remineralization environment. Molecular dynamics simulations elucidate the main adsorption mechanism that the positively charged amino acid residues in the bioactive peptide bind to phosphate groups on the tooth surface, and the main mineralization mechanism that the negative charges on the outermost layer of the bioactive peptide repel acetic acid ions and attract calcium ions as nucleation sites for remineralization. This study suggests that this in-house synthesized dual-bioactive peptide is a promising functional agent to prevent dental caries, and is effective in inducing in situ self-healing remineralization for the treatment of decayed teeth.
