In the present study, four β-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 β-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.

在本研究中，制备了四种 β-TCP/ZrO ₂水泥组合物，其中氧化锆在 0.25、0.5、0.75 和 1 wt% 的不同含量下变化。这项研究的目的是：（i）分析氧化锆的机械性能对不同水泥样品的影响，（ii）评估在不同时间浸入人造唾液中所有水泥中羟基磷灰石的体外形成，以及（ iii) 分析 I 型玻璃离聚物在所有 β-TCP/ZrO ₂水泥组合物中的相互作用。结果发现，与没有氧化锆的样品相比，添加到水泥组合物中的氧化锆的量不会显着影响机械性能的值。尽管如此，ZrO ₂有助于在不同时间稳定与人工唾液接触的各类水泥的脱矿质。另一方面，用于连接粉末水泥的玻璃离聚物类型 I 引起了机械性能的变化，增强了所有水泥组合物的可塑性。体外测试允许对浸入人造唾液中的水泥样品进行分析，结果表明三天后 pH 值从 7 降低到 3.8。
