Comparative evaluation for microleakage between Fuji-VII glass ionomer cement and light-cured unfilled resin: a combined in vivo in vitro study.
Glass ionomer cement, besides being used as restorative material, can also be used as pit and fissure sealant. The use of glass ionomer cement as pit and fissure sealant has added benefit by its fluoride-releasing property that results in increased resistance of the fissures to demineralize. The capacity of a sealant to prevent microleakage into the fissure is important, since microleakage may initiate and support a carious lesion beneath the sealant. The study was carried out to compare marginal microleakage between Fuji-VII glass ionomer cement (G C Corporation, Tokyo, Japan) and the conventional light-cured unfilled resin as pit and fissure sealants (3M Concise, 3M Dental Products, St. Paul, USA). The dye used was 2% methylene blue (Qualigens Fine Chemicals, Mumbai, India). The teeth were sectioned and studied under the stereomicroscope. The result revealed that there was no difference in microleakage (P > 0.05) between the two materials.
