Research Abstract

The durability of resinous material is one of the important factors needed to filling materials for minimal invasive caries treatment. To detect the durability-inhibitive process biodegradation, we offered the strategy using antioxidant agent Colloidal Platinum Nanoparticles. With these studies, we found out the observation technique of ultrastructural morphology on teeth using High Voltage Electron Microscope, and got atomic images of crystalline hard tissue.
