The objective of this study was to investigate the effect of different incubation periods on the push-out
bond strength and microhardness
of calcium-silicate-
based
materials: MTA-Angelus,
Biodentine and BIOfactor MTA. A total of 100 dentine discs
were used for the push-out
test. Three cavities were prepared on each dentine disc. Each cavity on the same disc was filled with
MTA-Angelus,
Biodentine or BIOfactor MTA. Half of the dentine samples were incubated at 37°C for 1 day, and the other half for
28 days (n = 50). Push-out
testing was then performed. For the microhardness test, material discs were prepared by mixing the
materials and placing them into Teflon moulds (n = 26). The samples were incubated at 37°C for either 1 day or 28 days (n = 13).
Vickers microhardness testing was conducted. The data were statistically analysed. The results showed that Biodentine exhibited
the highest bond strength and microhardness at both time points, while MTA-Angelus
showed the lowest (p < 0.05). Overall,
Biodentine demonstrated superior performance, while BIOfactor MTA showed promising but moderate results.
