    Comparison of Surface Roughness between Nano Hybrid and Nanocomposite Composites
    Author(s): Janani K* and Subash Sharma

    Composite is usually a mixture of two phases. The composites used in dentistry have high durability. The individual properties of each phase are important to increase the mechanical property of the composite. This study aimed to determine the surface roughness changes of two composite resin restorative materials after thermocycling. Two of the commercially available composites were chosen (Nanocomposite 3M Z350 and Nanohybrid composite 3M Z250). The composite disks of dimension 10mm diameter and 3mm height were prepared using silicone molds, and every increment was light cured for 30s. A stylus profilometer was used to assess the surface roughness pre thermocycling, and then, the disks were subjected to an integrated thermocycler (T.S-4.4) for 1000 cycles. The post surface roughness was obtained after the thermocycling process using the same stylus profilometer. The surface parameter .. Read More»
