SUCCESS & ENDURING LEGACY
Honours, Standing & Enduring Legacy
Doweidar also obtained a patent with two researchers for the preparation of a biologically active glass ionomer cement as a dental filling, characterized by vital activity due to the presence of bioactive crystalline phases in the retina glass (such as apatite and fluoroapatite), which react with SBF simulating solution to precipitate layers of hydroxyapatite and hydroxyapatite.
