Graphene Nanoparticles (GNPs), an upshot of nanotechnology have attracted great interest in diverse research fields including dentistry for their unique properties. Graphene Nanoparticles are cytocompatible and when combined with other compounds, they possess improved synergistic antimicrobial and anti-adherence properties against oral pathogens. The cytotoxicity of graphene in the oral setting has been reported to be very limited in the scientific literature. Current applications of graphene include reinforcing Polymethylmethacrylate (PMMA) for the fabrication of dentures, improving properties of dental luting agents like glass ionomer cement, reinforcing restorative composites and ceramics, and improving osseointegration of titanium dental implants by coating with graphene. This paper reviews the nanoparticle ‘Graphene’ and its potential uses in the field of restorative dentistry.

HIGHLIGHTS
- Graphene and its nano-sized derivatives exhibit great versatility and peculiar properties.
- Graphene Nanoparticles are a potential antibacterial agent, and are highly effective in inhibiting the growth of dental pathogens.
- Increase in the modulus of rupture by174% by adding 2% Gr-Ag to the PMMA resin.
- The fracture toughness of raw zirconia ceramic is improved up to 175% by incorporating 0.09 wt% rGO.
- Graphene possesses an osteogenic property that enhances the expression of osteogenic genes like RUNX2, COL-I, and ALP, which boosts osteocalcin gene and protein expression, and consequently increases the deposition of mineralized matrix.
