Objectives: To test the surface wear of a glass-ionomer sealant material that uses a resin coat meant to protect the surface in comparison to a conventional glass-ionomer and a resin sealant material.Methods: The occlusal surface of 48 extracted human third molars were sealed with a resin (Clinpro), conventional high-viscosity glass-ionomer (KMEM) and a high-viscosity glass-ionomer with resin coat (Equia system).The Rub & Roll wear simulation device and ACTA wear abrasive slurry was used to mimic clinical wear.
