ABSTRACTGlass ionomer cements are widely used in restorative dentistry in multiple clinicalindications as permanent or temporary restorative materials, lining, bases, lutingmaterial for crown and bridgework, cementing bands and brackets for orthodontics,pit and fissure sealants and core material for prosthetic purposes. They are widelyused due to the properties of adhesion to tooth structure, anti-cariogenic effect due torelease of fluoride and biocompatibility due to the low coefficient of thermalexpansion and low toxicity to the pulp tissue. Mainly because of their importantcharacteristic of low toxicity to pulp they are typically used as a protector of the pulpdentincomplex on the bottom of restorative materials as amalgam and compositeresin The present study aims to determine, through literature review, the bondstrength of glass ionomer cement to composite resin restorations highlightingquestions about pre- treatment of the surface of the material, effect of the cureprocess and available techniques. The literature review was conducted in thefollowing databases: PUBMED, CAPES Periodicals, SCIELO, BBO, BIREME andLILACS. The selection of the papers was performed using the following descriptors inPortuguese/English: cimento de ionômero de vidro/glass ionomer cement, resinacomposta/composite resin, resistência de união/bond strength, propriedadesmecânicas/mechanical properties. Articles published between 1995 and 2010 wereselected. Initially, 110 articles were selected and, after carefully refining, 23 articleswere used. Among various options presented in the literature to promote adhesionbetween the glass ionomer cement and composite resin it can be observed thatdifferent variables are involved. The composition of the cement, the elapsed timebetween placing the cement and the completion of the restoration, and the techniqueare important factors. The bond between resin modified cement and composite resinpresented higher values than for the conventional cement. It is Indicated the bondbetween cement and composite resin to be performed immediately, regardless of thetype of cement. The use of self-etching adhesives increases the bond strengthbetween the materials when applied before the initial setting of the ionomer.Adhesives with a composition similar to resin ionomer increases the bond strengthwhen used after the initial setting of cement. The technique of co-polymerizationappears to increase the bond strength between the materials.Key words: glass ionomer cement, composite resin, bond strength. mechanicalproperties.
