Glass Ionomer Coating with Nano-filled Resin versus Resin Reinforced Glass Ionomer as a Restorative Materials for Primary Molars

Introduction : Glass Ionomer Coating (GICs) are a special group of dental materials having some very unique properties. They adhere to slightly moist enamel and dentin without the need for any adhesive system, they release fluoride and thus have anticariogenic effects for an extended period, they can absorb and release fluoride from topical fluoride solutions, they have thermal expansion similar to enamel, and they are biocompatible with a low toxicity. Aim: the current study was to evaluate and compare; the clinical performance of GIC with surface coat versus resin modified GI restorations in primary molars in vivo. Materials and Methods: 24 children had bilateral carious class I molars fulfilling the inclusion criteria were selected. 48 molars were divided using split mouth technique into two groups; Equia-forte Group : 24 primary molar teeth with class I cavities were filled with glass ionomer (equia forte fil) followed by coating with (Equia forte coat) in the right side to all patients. Riva Lc Group : 24 primary molar teeth with class I cavities were filled with resin reinforced glass ionomer (Riva light cure) in the left side to all patients. All restorations were evaluated according to modified USPHS criteria at 1,3,6,9,12 months. Results: There was no significant difference between Equia forte fil and Riva Lc. Conclusion: Both Equia Forte and Riva LC restorations showed successful performance in class I cavities in primary molars after 1 year according to modified USPHS criteria, Both Equia Forte and Riva LC restorations could be used as variable options for restoring class I cavities in primary molars.
