摘要
目的筛选能够长期释放氟的复合氟化物,并探讨三种水门汀粉末中填加复合氟化物制剂的影响。方法在三种水门汀粉末中添加复合氟化物0%～20%,调和水门汀,观察其固化时间、抗压强度、氟离子释放量。结果添加适量复合氟化物对水门汀的抗压强度没有影响(P>0.05),添加复合氟化物使聚羧酸锌水门汀和玻璃离子水门汀固化时间明显延长,而对磷酸锌水门汀固化时间影响甚少。结论氟化物适当地添加于三种水门汀粉末中,不仅能够增强水门汀抗压强度,而且能够长期持续地释放氟。
Objective To choose the Co-F agent which continually released fluoride and to study the effect of three kinds of cements in which Co-F agent was added. Methods The three kinds of cement of powder for each cement which contained from no Co-F to 20 percent and mixed with the mixing liquid,the setting time,the compressive strength（24 hours） and the amount of the releasing fluoride were observed. Results The compressive strength of each cement with Co-F was not affected compared with that without Co-F agent（P ;〉 0. 05）. The setting time of hydroxyaptite and glass ions cements with Co-F were longer but there was little effect on zinc phosphate cements. Conclusion The Co-F agent added to dental cement can not only improve the compressive strength but also continually release fluoride.
