Comparative assessment of light-cured resin-modified glass ionomer and composite resin adhesives: In vitro study of a new adhesive system

The ideal adhesive system is one that prevents decalcifications and has suf ficient bond strength to withstand untimely impact forces on bonded bracket s. The purpose of this investigation was to study and compare the bond stre ngths and adhesive remnant indexes of light-cured resin-modified glass iono mer and conventional resin adhesives. A new light-cured resin-modified glas s ionomer adhesive was compared with the conventional adhesive systems. The effects of the new adhesive, with a system of etching and using adhesive p romoters on the tooth enamel, as well as microetching the brackets, were an alyzed. Comparisons were made (analysis of variance and the Tukey method) b etween this and other adhesive systems. The new adhesive system is indicate d where prevention of decalcification and increased bond strength in noncom pliant patients ate indicated.
