Antibacterial Nanomaterials
This category explores metallic nanoparticles like AgNPs and ZnO NPs, cationic monomers such as DMAHDM, and natural nanopolymers including Chitosan and Graphene Oxide. These materials aim to reduce bacterial adhesion and metabolic activity through various mechanisms, including ion release, ROS generation, and contact-killing effects. Their integration into composites, adhesives, and cements is a central strategy for preventing secondary caries and inflammation, though considerations for cytotoxicity, discoloration, and long-term stability remain.
Bioregenerative Nanomaterials
Focusing on materials that support natural biological processes, this section delves into Nanohydroxyapatite (nHAp), Bioglass (BG), Amorphous Calcium Phosphate (NACP), and Calcium Silicates. These systems promote remineralization, dentin-pulp regeneration, and reduction of hypersensitivity by releasing bioactive ions (Ca²⁺, PO₄³⁻, Si⁴⁺) and stimulating apatite formation. Their goal is to stabilize the tooth–material interface and preserve pulp vitality, moving beyond passive structural replacement.
Dual-Function Materials
Representing an emerging frontier, dual-function nanomaterials combine both antibacterial and bioregenerative properties within a single system. Examples include NACP-DMAHDM composites, Ag-nHAp, and ZnO-bioglass hybrids. These materials are designed for synergistic action, offering adaptive responses to the oral environment, such as pH-triggered ion release, to inhibit bacteria and simultaneously promote tissue healing. The challenge lies in balancing these functionalities for optimal mechanical reliability and long-term efficacy.
Technological Advances & Future Trends
This area covers the cutting-edge developments in nanomanufacturing, 3D printing, artificial intelligence, and smart materials. These technologies enable the precise design and fabrication of personalized restorative solutions with tailored biological and mechanical properties. Smart materials respond to environmental stimuli, while AI and machine learning optimize material composition. Regulatory frameworks and sustainability considerations are crucial for their successful translation into routine clinical practice.

Case Study: NACP-DMAHDM Composites for Adaptive Dental Repair
One of the most representative dual-function systems is the composite based on nano-calcium phosphate (NACP) and dimethylaminohexadecyl methacrylate (DMAHDM). NACP provides remineralizing ions and a pH-responsive effect in acidic conditions, while DMAHDM exerts antibacterial action through contact killing. In vitro studies demonstrate a significant reduction in the viability of S. mutans biofilm and a tendency to restore local pH. This integration into adhesives/cements offers double protection without altering mechanical properties, showcasing adaptive behavior in the oral environment. Such systems represent a significant step towards "smart" restorative materials that actively manage biofilm and promote tissue health.
