Abstract
The flexural strength of five glass ionomers was measured at intervals ranging from 1 h to 3 months after mixing. The pattern of change in flexural strength is material-specific with two water-activated materials having significantly higher long-term flexural strengths than the others. This may be attributable to the different polyacrylic acids used or to changes in the glass formation in the different materials.Entities:
