AI Technical Summary
Technical Problem
Existing dental cements struggle to provide high adhesion quality in moist environments, leading to issues like microleakage in prosthetic fixed restorations, and there is a need for improved bonding between different dental materials.
Method used
A polydopamine-containing bioactive resin cement is developed by adding polydopamine between 10-25% by weight to a resin monomer mixture, using polydopamine-grafted nanoparticles in emulsions, and employing emulsion polymerization to enhance adhesion, particularly in moist conditions.
Benefits of technology
The cement exhibits enhanced bond strength, achieving approximately 45N for enamel bonding and 40N for dentin bonding, outperforming conventional cements, and reduces microleakage.
