Description
Ildefonso Serrano-Belmonte and co-authors compare colour staying power between standard and graphene-reinforced dental PMMA, in a 2026 lab study. Temporary crowns can discolour in the mouth, hurting appearance. Eighty discs were split across set-ups combining saliva-like acidity changes, coffee exposure, and simulated chewing movements, with colour measured before and after.
Both materials changed colour measurably. The graphene version changed less in the coffee and combined conditions, where the gap reached statistical significance. Plain PMMA exposed to coffee passed the clinical acceptability threshold for colour change. Neither material stayed fully stable, so the authors present graphene reinforcement as an improvement, not a cure.
