| Abstract | ||
| This study was done to assist microleakage of glass ionomer cement reinforced by different amount of Hydroxyapatite. 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 mixed materials was used as filling for class V cavities in extracted premolars bucally and lingually and microleakage was detected by dye penetration methods.The results showed that glass ionomer cement reinforced by different amount of Hydroxyapatite has less microleakge at tooth / restoration interfaces than conventional glass ionomer cement. The addition of hydroxyapatite to conventional glass ionomer cement used as filling for class V cavity preparation causes reduction in microleakage at tooth / restoration interfaces | ||
