Highlights • The biological effects induced in vitro by three graphene-based nanomaterials on human dental follicle stem cells, were evaluated. • Graphene oxide showed the lowest cytotoxic effect, followed by the nitrogen-doped graphene. • Thermally reduced graphene oxide exhibited high cytotoxic effects.
Research suggests we chew around 800X in an average meal; that’s almost a million times a year. We put our teeth under huge strain, and often require fillings to repair them. Fillings are typically made of a mixture of metals, such as copper, mercury, silver and tin, or composites of powdered glass and ceramic...
