| Background: the aim of the present study was to evaluate and compare microleakage and marginal gaps of five different types of glass-ionomer restorations after aging in apple and lemon juices. Materials and Methods: One hundred and fifty sound teeth prepared with standardized Class V preparations on buccal and lingual aspects with dentin/cementum gingival margins. They were divided into five groups and restored using; Fuji IX GP FAST, riva HV, EQUIA fill, Fuji II LC, Micron bioactive. Every group was further distributed into three subgroups: subgroup 1 was immersed in distilled water (DW) as control, subgroup 2 was immersed in apple juice (AJ), and subgroup 3 was immersed in lemon juice (LJ). Each subgroup was distributed equally for marginal adaptation and microleakage testing (n=10). The interfaces of restoration/gingival dentin were detected by scanning electron microscopy (SEM) to measure gaps for marginal adaptation assessment. For microleakage, samples were submerged in 2% methylene blue dye solution. Then, they sectioned labio-lingually at the middle of the teeth. The dye penetration alongside the gingival margins was assessed on buccal and lingual surfaces under a stereomicroscope. Results: One way ANOVA test showed statistical significance among all tested GIs for marginal adaptation and microleakage and paired-t test showed significant differences for AJ and LJ. Conclusions: The marginal integrity of glass-ionomers was negatively affected by popular acidic fruit juices. ; Riva HV and EQUIA Fil, and RMGI Fuji II LC are considered less affected by these acidic juices. | ||||
