  • EVAPORATION STRATEGY GENERATED ANTIBACTERIAL ENAMEL-LIKE FLUORAPATITE-POLYACRYLIC ACID SHEET FOR FUNCTIONAL DENTAL RESTORATION
    Publication number: 20230141188
    Abstract: The subject invention pertains to an evaporation strategy combined with low-molecular-weight polyacrylic acid (LPAA) to generate an antibacterial dental enamel-like structure. Polystyrene (PS) plates can be used as a removable substrate for the continuous growth of fluorapatite (FAP). The FAP-LPAA composition can be used to kill microorganisms. The LPAA contained dental enamel-like FAP provides an alternative to prevent secondary caries if a carious cavity is filled with shaped dental enamel-like FAP-LPAA.
