Abstract
It is claimed that light-activated hybrid glass ionomer cements offer advantages over the conventional glass ionomer lining materials. The compressive strengths and erosion rates of two hybrid glass ionomer lining cements, when light activated and chemically set, were compared with conventional glass ionomer cements. The results demonstrated that the erosion rates of the light-activated materials were comparable with those of the conventional materials. The conventional material, Ketac-Bond, was stronger than the light-activated hybrids. When the hybrid materials were allowed to set chemically alone, their performance was inferior to the conventional glass ionomer lining cements.
