Assessment of shear bond strength of glass ionomer cement reinforced by different amounts of Hydroxyapatite
Background: This study was done to assist bond strength of glass ionomer cement reinforced by different amount of Hydroxyapatite Materials and methods: In this study a hydroxyapatite materials were added to glass ionomer cement at different ratios; 10%, 15%, 20%, 25% and 30% (by weight) and the bon...
