Resumo
Glass ionomer cements are widely used as protectors of the
pulp-dentin complex. This study aimed to examine, through a
literature review, how adhesive bonding is established
between those cements and composite resin restorations. A
bibliographic research was conducted in the databases:
PubMed, CAPES, SCIELO, BBO, LILACS and BIREME. Papers
were selected using the descriptors (Portuguese / English):
cimentos de ionômeros de vidro/glass ionomer cements,
resinas compostas/composite resins. The period determined
for their selection was set between 1995 and 2010, and
after filtration, 23 articles were selected. It was observed
that different variables are involved in the process of bond
strength between glass ionomer and composite resin. The
composition, the elapsed time between the insertion of the
cement and execution of the restoration, as well as the
restorative technique are important factors. The resinmodified
cements presented results clinically superior to those
found for conventional cements. Bonding between cement
and composite resin should be performed immediately after
insertion of the cement in the prepared cavity. The self-etching
adhesive system increased bond strength values when
applied over glass ionomer before initial setting. Adhesives
with a composition similar to that of resin modified ionomer
increased bond strength after cement’s setting.
