Description
Summary:To appraise influence of polymerisation of restorative dental composites on physical, mechanical and chemical properties at various setting depths. The cylindrical samples (5 mm diameter, 2.5 mm height, and n = 6) of microhybrid and nanohybrid composites were fabricated. Nanohardness was performed from the surface to the core of the sample in stages, i.e., stage 1-5. Additional chemical and physical characterisations of the study materials were performed. Differences in nanohardness, and W sl and W sp values were evaluated using analysis of variance (P ≤ 0.05). Nanohardness was significantly affected between stages of dental composites (P
