Radiopacity of Glass lonomer Cements

Abstract

The purpose study was to test nine commercial brands of glass ionomer (Chelor Fill, Chelon Silver, Fuji II LC, Variglass Azul Variglass DY, Vitrebond, Vitremer Cimentaçãc e Vitremer Restauração) in order to identify one that is most radiopaque. This informatior would help in a future radiographic diagnosis o: analysis. In carrying out this experiment, nine glas ionomer samples were made from the nine brands mentioned above, and the oclusal anc apical regions of nine premolars teeth wert restored. Later, the samples as well as the restoœc premolars wcre submited to radiographi¿ exposure. The subjects went through densitometric evaluation, and the premola5 were visually evaluated by ten observers. In both densitometric and visua. evaluation, the results showed Chelon Silver as the most radiopaque of the glass ionome: followcd by Variglass DY. The least radiopaqut was Chelon Fili.
