Abstract :
Composite restorative material is one of the most accomplished contemporary biomaterials because of its high aesthetic potential with satisfactory clinical durability. Although composites are favourable restorative material their polymerization shrinkage still remains a challenge. Recently, Science of Nanotechnology has invaded into the field of Dentistry in an attempt to offset the existing shortcomings of traditional dental composites and substantially improving its properties by adding nano sized filler particles like Silver, Titanium Dioxide, Zirconia and Silicone. Graphene Nanoparticles (GNP) are novel fillers that possess a high fracture strength, mechanical strength, chemical stability, flexibility, they are also biocompatible and non-cytotoxic. The objective of this study is to evaluate the Surface roughness, Microhardness and Flexural strength of Nano hybrid composite resin modified with Graphene nanoparticles after subjecting the specimens to Thermo Mechanical cyclic loading.
