The invention provides a bonding-assisting biological material and applications of the bonding-assisting biological material in biomimetic mineralization, for promoting the remineralization of type I collagen, demineralized enamel and dentin. The bonding-assisting biological mineralization material is the synthetized amorphous calcium phosphate particles stabilized by non-collagenous protein analogue. According to the applications of the bonding-assisting biological mineralization material in biomimetic mineralization, the assisting mineralization material is mixed with a self-etching adhesive, thus the bonding-assisting biological mineralizer is prepared, the bonding-assisting biological mineralizer coats the surfaces of single-layer recombinant type I collagen, the demineralized enamel and the dentin, and then the mineralization property of the biological mineralizer for the single-layer recombinant type I collagen, the demineralized enamel and the dentin is studied. The existing biological mineralization mode (solutions and paste are adopted, namely, gargling or local coating is adopted) is changed, the assisting mineralization material is mixed with the adhesive, after curing, the liquid state is converted into the solid state, then the adhesive anti-caries coating is formed, and the adhesive anti-caries coating can be adhered to the part needing mineralization for a long term, so that the acting time with teeth is prolonged, the use is simple and convenient, and the self-repairing of the demineralized teeth is promoted.
