Abstract

Aims and Objectives: The purpose of this in vitro study was to investigate the effect of polishing on the microleakage of five different Glass Ionomer restorative materials.
Materials and Methods: Class V cavities were prepared at the labial surfaces of 50 freshly extracted primary anterior teeth. The prepared teeth were randomly divided into five groups and restored with Equia Fort, photac fil, Ketac molar, riva self cure and Fuji IX. each group was further subdivided into two subgroups (polished and not polished) of 5 teeth each. Finishing and polishing of the polished group was done using the Sof-Lex polishing system. Furthermore, all the restorations were subjected to dye penetration testing.
Results: EQUIA specimens showed the least microleakage which was significantly better than the rest of groups. Maximum microleakage scores were observed in specimens of groups III and V (ketac molar and fuji IX). There was no significant difference between polished and non polished specimens of each group.
Conclusions: Generally, resin modified glass ionomer cements produced more favorable results than conventional glass ionomer in terms of microleakage, with the exception of EQUIA, exhibiting excellent results. Also, polishing of glass ionomer restorations has no effect on marginal microleakage.
