| Outline of Final Research Achievements |
For most restorative composite resins, there were significant color differences (ΔE*) in the region of intraoral temperatures from 4 to 60℃.Thermal dependence of refractive index of dimethacrylate resins used in composite resin in the region of intraoral temperature would cause the thermochromism of restorative composite resins.
