Abstract: [06] The long-term durability of resin–dentin bonding remains a major challenge in restorative dentistry because the hybrid layer is vulnerable to hydrolytic degradation, collagen breakdown, matrix metalloproteinase activity, microleakage, and secondary caries. Although modern universal adhesive systems have improved clinical handling and immediate bonding performance, the resin–dentin interface still undergoes progressive deterioration under oral moisture, thermal stress, and bacterial challenge. The present work proposes GRAPHODENT, a graphene-induced eighth-generation dentin bonding concept in which graphene nanoparticles are incorporated into a universal adhesive matrix to provide simultaneous nano-mechanical reinforcement, antibacterial action, improved interfacial infiltration, and potential enzymatic degradation resistance. Experimental adhesive groups were designed using a control adhesive without graphene nanoparticles, a 0.1 wt% graphene nanoparticle formulation designated A01, and a 0.2 wt% formulation designated A02. The preparation method involved controlled dispersion of graphene nanoparticles into the adhesive base, slow-rate solvent evaporation under continuous mechanical stirring for 6–12 h, and adhesive application with controlled air-flushing at 0.2 bar. The proposed system is intended to strengthen the hybrid layer, reduce crack propagation, inhibit bacterial colonization near restoration margins, and improve resin infiltration into dentinal tubules.
