Conventional glass-ionomer cements (GICs) have proven less satisfactory than amalgam as primary Class II restorations, but resin-modified GICs have shown more promising results in cohort studies. In this study, 40 children aged 4-7 yrs received 62 conventional GIC and 53 resin-modified GIC restorations on a split mouth basis. All restorations were placed under LA without rubber dam.

After median follow-up of 36 months, 96% of resin modified (RM) GICs were successful, and 82% of conventional (C) GICs. Failure incidence of RMGICs was 13 per 100 restored tooth-yrs, and of CGICs, 62 The authors considered RMGICs to be clinically advantageous.
