White spot lesions (WSLs) and demineralized enamel surfaces are common dental issues that can lead to further complications if untreated. The potential of various remineralizing agents has been extensively studied, but the efficacy of polyamidoamine (PAMAM) dendrimers in promoting enamel remineralization remains to be fully elucidated. This systematic review aims to evaluate the remineralizing potential of PAMAM on WSLs and demineralized enamel surfaces. To identify relevant studies, a comprehensive literature search was conducted across multiple databases, including PubMed, Scopus, and Cochrane Library. Inclusion criteria comprised in vitro and in vivo studies that assessed the effects of PAMAM on WSLs or demineralized enamel. Data extraction and quality assessment were performed independently by two reviewers. The primary outcomes measured were changes in enamel microhardness, surface morphology, and mineral content. Five studies met the inclusion criteria, comprising in vitro studies. The results indicated that PAMAM demonstrated a significant remineralizing effect on demineralized enamel surfaces, as evidenced by increased microhardness and improved surface morphology. The studies varied in their methodological approaches but collectively supported the potential of PAMAM in enamel remineralization. PAMAM dendrimers exhibit promising remineralizing properties for treating WSLs and demineralized enamel surfaces.
