Polyamide-amine and chlorhexidine compound, and preparation method and application thereof

The invention belongs to the technical field of biological medicines, and relates to a compound containing polyamide-amine, and a preparation method and application of the compound, and in particularrelates to a polyamide-amine and chlorhexidine compound, and a preparation method and application thereof. The polyamide-amine and chlorhexidine compound comprises a polyamide-amine dendritic polymerand chlorhexidine gluconate, and the chlorhexidine gluconate is attached to the polyamide-amine dendritic polymer. The compound can promote dentin remineralization, so that micro-leakage gaps of a bonding interface of resin and dentin are sealed, and then the bonding long-term effect of the resin and the dentin is further improved. The compound formed by the polyamide-amine dendritic polymer and chlorhexidine gluconate can be used as a dentin remineralizer to be applied to medical practice.
