Novel self-healing dental resin with microcapsules of polymerizable triethylene glycol dimethacrylate and N,N-dihydroxyethyl-p-toluidine

- Bulk fracture is a primary reason for resin-based dental restoration failures.
- Self-healing resin contained microcapsules with TEGDMA-DHEPT healing liquid.
- A self-healing efficiency of 65% in KIC was obtained with 10-20% microcapsules.
- Self-healing resin-based restorations can heal cracks and increase the durability.
