Abstract
Aim of the study: assessment of the microhardness of Smart Dentine Replacement, Biodentine and Fuji liners in restoring permanent teeth. Methodology: For each test 27 samples were done for the vicker hardness test using circular split teflon mold with outer metallic ring (with outer ring 20mm diameter and 2 mm thickness was used to prepare the samples). Surface microhardness was measured using digital display Vickers micro-hardness tester. A load of 100g was applied to the surface of the specimens for a duration of 15 seconds. The indentations were spaced at least 0.5 mm apart. The diagonal lengths of these indentations were measured using built-in scaled microscope, and the Vickers values were converted into micro-hardness values. Results: For vicker hardness there was a significant difference between different groups, The highest value was found in SDR (79.99±4.10A) followed by Fuji II (60.80±1.87B) while the lowest value was found at Biodentine (51.73±2.78C). Conclusions: Smart dentine replacement has the highest value in vicker test.
