Summary: In this study, a functional nanocomposite of epigallocatechin gallate (EGCG) and amorphous calcium phosphate (ACP) was developed for the prevention and restoration of demineralization. The EGCG-ACP exhibited good biocompatibility and showed sustained release of ACP to restore the microstructure and mechanical properties of demineralized enamel under neutral conditions. Under acidic conditions, protonated EGCG exerted a strong antibacterial effect, preventing demineralization in the presence of cariogenic bacteria. The pH-responsive features of EGCG-ACP facilitated its performance in remineralization to overcome the difficulty of restoring demineralized enamel in a cariogenic acidic environment.

Summary: Enamel demineralization, a common dental problem, is a concern for dental professionals and patients due to its impact on both health and aesthetics. Amorphous calcium phosphate (ACP) has gained attention as a potential agent for preventing or treating enamel demineralization. This article briefly reviews ACP stabilizers and their mechanisms, as well as the scientific evidence supporting the remineralization ability of these agents. The limitations of current research and future prospects for clinical translation of ACP agents are also discussed.

Summary: The aim of this study was to determine the immediate and sustained effect of fluoride varnish and its combinations with toothpastes in preventing root caries development. The study found that all prevention protocols significantly decreased dentin porosity and increased mineral density. The combination of fluoride varnish with toothpaste showed superior anti-caries effects.

Summary: This study investigates the effects of 5% sodium fluoride varnish and 38% silver diamine fluoride on preventing demineralization of human enamel lesions of different severities. The results suggest that silver diamine fluoride may have comparable benefits to fluoride varnish in preventing mineral loss.

Summary: This study evaluated the remineralization of tooth enamel using one-pot coating with polydopamine and fluoride ions. The results showed that enamel coated with polydopamine and fluoride ions had the highest fluoride content and the lowest reduction in hardness. Scanning electron microscopy further supported the effect of the coating on enamel remineralization.

Summary: This study evaluated the effectiveness of Tooth Mousse compared to conventional fluoride-based versions in preventing enamel and dentin demineralization. Results showed that Tooth Mousse was less effective in preventing demineralization compared to fluoride toothpastes, but using Tooth Mousse during demineralization led to a reduced number of severe lesions.

Summary: The study aimed to evaluate the remineralization effect of calcium phosphate ion clusters (CPICs) on demineralized enamel surfaces and their effects on bracket shear bond strength. The results showed that CPIC treatment led to epitaxial growth of enamel, a decrease in demineralized enamel thickness, an increase in Ca/P ratio, and an improvement in microhardness. The radiolucency gradually decreased with longer CPIC treatment. The shear bond strength and adhesive remnant index results indicated improved bonding stability after CPIC treatment.

Summary: This study aimed to evaluate the changes in PO4-3 of enamel surfaces by using Raman analysis after applying three different remineralization agents containing Ca-PO4-3 in vitro. The study found that remineralizing agents have positive effects on the phosphate concentration of initial enamel caries, but there was no significant difference in PO4-3 changes between remineralized surfaces and intact surfaces.

Summary: This study developed a dual-functional nanocomposite with antibiofilm and remineralization properties, composed of zwitterionic poly(carboxybetaine acrylamide) and amorphous calcium phosphate. The nanocomposite exhibited significant inhibitory effects on bacterial adhesion and biofilm formation, and demonstrated bactericidal activities under acidic conditions. Furthermore, it showed better effects in promoting dental caries treatment compared to fluoride.

Summary: This review provides an overview of cutting-edge research on the development of new bioactive restorations to inhibit secondary caries in enamel and dentin under biofilms. Novel bioactive materials are categorized based on their remineralization and antibacterial biofunctions. However, there is still a need for new intelligent and pH-responsive materials, and the evaluation should be performed using more clinically relevant biofilm-based secondary caries models.

Summary: Assessment of enamel subsurface lesion remineralisation is crucial for evaluating novel remineralisation technologies. This study compared the efficacy of transverse microradiography (TMR) and surface microhardness (SMH) in assessing enamel remineralisation after treatment with calcium-containing technologies. Results showed that the parameters obtained from TMR and SMH analyses were not significantly correlated, suggesting that TMR is a more appropriate method for evaluating enamel subsurface remineralisation. The study also found a significant correlation between TMR measurements and the water-soluble calcium concentration of the remineralisation products.

Summary: Biofabrication has been utilized to engineer patient-specific biosynthetic grafts for bone regeneration, with a new 3D printing approach developed in this study using calcium phosphate cement (CPC) and non-aqueous CPC bioinks. The choice of PVB solvents, EtOH or THF, was found to affect the rheological properties, microstructure, mechanical properties, and osteoconductivity of the scaffolds. This novel method opens up possibilities for engineering high-resolution, implantable, and osteoconductive scaffolds with predetermined properties for bone regeneration.
