Objective: To assess the erosive wear rate of different tooth-coloured restorative materials under acidic conditions.
Methods: The present in vitro study evaluated the erosion of restorative materials by measuring their depth loss.
Results: Significant differences were recorded between the initial and final surface roughness of all tested materials (p<0.05). The mean erosive wear rates after exposure to citric acid ranged between 0.32-0.58 pm.
Conclusions: Under the experimental acidic conditions applied, all investigated restorative materials showed degradation. The highest depth loss was observed in a compomer and the lowest in a resin-modified glass ionomer cement.
