title: Abrasion resistance of restorative glass-ionomer cements with a light-cured surface coating.
abstract: This is a comparative study of the Knoop hardness number and the toothbrush wear of a surface coating agent applied to the surface of a glass-ionomer restorative cement. A reduction in surface hardness of the coating agent resulted in an increase in brush wear. The light-cured glazing agent (Bellfeel Brightener) proved to be significantly harder than those coated with a light-cured bonding agent (Occlusin). Occlusin bonding agent was removed by comparatively rapid abrasion; however, the Bellfeel Brightener was significantly more resistant to such abrasion. The analysis of the surface hardness and scanning electron microscopy observations of the brushed surfaces of the samples suggested that Bellfeel Brightener was effective as a glazing material for glass-ionomer cement restorations.
