Abstract :

 Nanocomposites is a anch of science which is involved in the production of materials which ranges from particle size between 0.1–100nm. The present study was conducted to analyze the bond strength and micro leakage of newer nanocomposite on enamel and dentin . 40 extracted teeth were used in the study and divided into 2 groups – Group1–20 samples IPS Empress direct + tetricNBond Group II– 20 samples filtek Z350 + adaper single bond 10 samples from each group was used to analyses the bond strength using instron testing machine and 10 samples for analysis of microleakage using stereomicroscope . The results showed that group I IPS Empress direct showed higher bond strength and less microleakage value compared to group II filtek Z350
