Unlabelled: Coloured compounds (anthocyanins) in açaí can stain resin-modified glass-ionomer cement (RMGIC) due to its low staining resistance.
Aim: The aim of this study was to assess whether açaí compromises the surface colour and roughness of RMGIC in vitro.
Materials And Method: Disc-shaped specimens (2 mm thick, 8 mm in diameter) of Vitremer™ (3M ESPE, St Paul, MN, USA) were prepared according to the manufacturer 's instructions.
