| Abstract |
| In the present study, four -TCP/ZrO2 cement compositions were made, in which the
zirconia was varied in different amounts at 0.25, 0.5, 0.75 and 1 wt%. The goals of this
investigation were: (i) To analyze the effect of the mechanical properties of zirconia
on the different samples of cement, (ii) To evaluate in vitro formation of hydroxyapatite
in all cements at different times dipping in artificial saliva, and (iii) To analyze the
interaction of glass-ionomer type I in all -TCP/ZrO2 cement compositions. The results
found were that the amount of zirconia added to the cement compositions did not
significantly affect the mechanical properties’ values compared to the sample without
zirconia. Nevertheless, ZrO2 helped to stabilize the demineralization of the types of
cement in contact with artificial saliva at different times. On the other hand, the glass
ionomer type I used to link the powder cement caused a change in the mechanical
behavior, enhancing the plasticity in all the cement compositions. The in vitro test
allowed an analysis of the cement samples dipping in artificial saliva, which showed
a decrease of pH value from 7 to 3.8 at three days.
