An invitro study was undertaken to evaluate the scaling properties of GIC when used as linear and applied at different levels on the internal cavity walls in class II composite resin restorations. 45 freshly extracted human maxillary premolars were selected to evaluated for microleakage. After standardization conventional class II cavity preparation, they were randomly divided into 3 groups of 15 teeth each. After various procedures of restoration for each group, they were immersed in Basic Fuschin Dye and the extent of the dye penetration was evaluated by stereomicroscope. The statistical analysis of the results of microleakage showed that there was no significant difference in the degree of microleakage between group A and group B. But there was significant reduction in the degree of microleakage in the group of teeth in which composite resin was done after applying GIC liner on the pulpal floor, axial wall and gingival seat up to the cavosurface margin (Group C) when compared with other two.
