Aims : To evaluate the effect of two fibers (polyethylene or glass) and a flowable resin liner on microleakage in Class II adhesive restorations. Materials and Methods : Class II cavities were prepared on mesial and distal surfaces of 40 extracted sound human molars. The cavity margins were below the CEJ on one side and above the CEJ on the other. The teeth were randomly divided into four groups according to the restoration technique: group 1: restored with a resin composite in bulk after SE Bond application; group 2: flowable resin liner was used before composite restoration; group 3: polyethylene fibre and in group 4: glass fiber was placed into the bed of flowable resin before composite restoration. Samples were finished, stored in distilled water and then thermocycled. Apices were sealed and tooth surfaces were coated with nail polish within 1 mm of the margins and placed in basic fuschin dye for 24 h at 37ºC. Teeth were rinsed and sectioned longitudinally through the restorations. Microleakage was evaluated and scored. Statistical Analysis Used : Kruskal-Wallis, Mann-Whitney U-test. Results : Flowable resin, everStick NET, and Ribbond THM used in combination with flowable resin significantly reduced leakage at occlusal enamel margins (P<0.05). Conclusions : Use of flowable composite alone or in combination with polyethylene or glass fibers reduces occlusal leakage in Class II adhesive cavities with enamel margins.
