Background: Composites require more manual dexterity and time to place when compared to the amalgam restoration. Due to this, recently composites have been manufactured by densely loaded fillers with hybrid composites. These composites have an increased wear resistance and increased stiffness. Materials & Methods: Forty tooth were taken and two cavities were prepared on mesial and distal surfaces. One cavity was restored with composite without liner and the other was restored with composite liner. Both were kept in dye and later it was observed under microscope for microleakage. Results: In group A and group B samples, Cavities restored only with packable composite had significantly higher micro leakage than cavities lined with fluid composite. GROUP A [P=0.006; P=O.O24], GROUP B [P=0.000; P=O.O09]. Conclusion: Microleakage was more prominent in the restorations which were not lined with flowable composites when compared with the restorations which were lined by the liners..
Keywords: Composite resin, liner, microleakage.
