DSC diagram of microcapsules containing TEGDMA-DHEPT healing liquid inside PUF shells. The exothermic peak at 162 °C was due to polymerization of TEGDMA by the high temperature. The endothermic valley at 307 °C was related to PUF shell decomposition. These microcapsules were stable up to 150 °C, indicating suitability for use at temperatures in vivo in dentistry.
