Surface texture and enamel-restoration interface of glass ionomer restorations.
The aim of this study was to investigate the surface texture and enamel-restoration interface of Class II glass ionomer restorations in primary molars. A traditional (Chemfil II), a cermet (Chelon-Silver) cement and two light cured glass ionomer cements (Vitremer and Dyract) were used to restore the Class II cavities of 20 primary molars. The surface changes and enamel-restoration interface of restorative materials were evaluated by SEM, after a 12 month period. Microcracks and pores in surface were observed in all of the four different glass ionomer materials. Although, there was no marginal gap formation for Chemfil II, Chelon-Silver and Dyract samples, in 2 samples of Vitremer group gap formation was found with an ion-exchange layer. Also, in Dyract samples wear of restorations was considerable.
