Abstract :
Aim: To comparatively evaluate the compressive
strength and microhardness of Alkasite restorative
material with Light cure-composite, RMGIC, Dual-cure
composite resin under thermocycling conditions.
Materials& methods: Metal cylindrical mold of
dimension 6±1mm (Height) ×4±1mm (diameter) was
used to fabricate 20 samples of Alkasite, Light-cure
composite resin, Resin modified GIC and Dual-cure
composite resin each. Samples were tested using Vicker
hardness tester and universal testing machine.
Statistical Analysis Used: Data were analyzed
statistically using the ANOVA, Tukey’s HSD test)
Results: The statistical difference between the hardness
values of different groups was found to be statistically
significant. There was no statistically significant
difference in the values ofcompressive strength between
the groups.
Conclusions: Within the limitations of the study, it can
be concluded that: RMGIC had highest microhardness
with and without thermocycling and Cention-N had
highest compressive strength after thermocycling.
Cention -N can be used as a best material for core-build-
up.
