[Development of novel self-adhesive resin cement with antibacterial and self-healing properties].

Objective: This study aimed to develop novel self-adhesive resin cement with antibacterial and self-healing properties. Furthermore, the dentin bonding strength, mechanical properties, self-healing efficiency, and antibacterial property of the developed cement were measured.

Methods: Novel nano-antibacterial inorganic fillers that contain quaternary ammonium salts with long-chain alkyls were synthesized.

[Application and potential future directions of self-healing polymers in dentistry].

Self-healing materials have rapidly developed in recent years to overcome the micro-cracks occurring in the polymer matrix. Self-healing ability offers autonomous crack repairs to prolong the service lives of polymers or polymer composites. As a main approach, extrinsic self-healing materials based on microcapsules have been applied in dentistry recently.

[Effect of water immersion on a dental self-healing and antibacterial resin composite].

Objective: This investigation aimed to develop a novel self-healing and antibacterial dental resin composite. The effects of water immersion on its properties were also evaluated.

Methods: Microcapsules filled with healing agent of triethylene glycol dimethacrylate were synthesized on the basis of previous studies.
