We examined its storage stability. The solution underwent comprehensive characterization using various techniques, including Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD), Transmission Electron Microscopy (TEM), STEM-EDX mapping, and Selected Area Electron Diffraction (SAED). Additionally, remineralization of demineralized dentin was induced by both control groups and the PAMAM-COOH/ACMP-MDP group. The effects were observed using a laser scanning confocal fluorescence microscope (CLSM), scanning electron microscopy (SEM), and TEM.Results: The PAMAM-COOH/ACMP-MDP ethanol solution we prepared maintained stable physicochemical properties after two months of storage. It exhibited good dispersibility, retained an amorphous phase, and maintained a nanometer size with excellent stability. The results from CLSM indicated that, compared to the control group, the PAMAM-COOH/ACMP-MDP ethanol solution could induce partial remineralization of demineralized dentin in deeper dentin tubules. The SEM results indicated that the PAMAM-COOH/ACMP-MDP group exhibited distinct characteristics of collagen fiber remineralization, both on the surface and within the deep dentin tubules. The collagen fibers in this group were thicker and more mineralized. Furthermore, significant remineralization features of collagen fibers were observed in the peritubular dentin of the PAMAM-COOH/ACMP-MDP group as evidenced by TEM.Conclusion: The PAMAM-COOH/ACMP-MDP ethanol solution exhibits thermodynamic stability, uniform dispersion, and the capability to induce remineralization of demineralized dentin collagen fibers. These findings highlight the potential of dendritic macromolecules for the biomimetic mineralization of dentin collagen and underscore the feasibility of utilizing ethanol-based primers in the development of new adhesives and their clinical applications.Keywords: nanocomposite, dentin remineralization, polyamidoamine, collagen |
