Abstract

Introduction. Glass ionomer materials have been, used for years as liners, bases and temporary restoration for children. Their bonding properties allow temporization, which would be difficult with conventional cements of restorative materials. The desirable properties include easy and rapid application, fluoride release, biocompatibility and adhesion to dentin and enamel tend to be used in children specially for precooperative or handicapped children and preclude the need for treatment using general anesthesia of sedation in this research, shear bond strength of glass ionomer in two groups, including normal group and hypoplastic enamel group is tested. Methods. For this purpose, 2 groups each including 12 samples of normal anterior deciduous teeth and hypoplastic anterior deciduous teeth (with attention to hypoplastic indices) were chosen. The labial surface of teeth were prepared with medium and fine size discs, chem fil GLASS IONOMER CEMENT was bonded to prepared surfaces of teeth, and then samples were fixed in special site of self curing acrylic. The specimens were tested with a model 4031 instron machine. A shear load was applied to the base of the bonded glass ionomer cylinder with a knife edge rod (width, 0.5 mm) at a cross head speed of 0.5 mm/mm.Results. The mean of obtained sbs for 2 groups was 16.35 and 11.63 KGF/mm2.Conclusions. Statistical analysis of the results showed significant defferences between studied groups. But with attention to desirable properties, application of GLASS IONOMER CEMENT in hypoplastic defects of enamel in children is recommended.
