Twelve prefabricated posts were cemented in extracted teeth with zinc phosphate cement, 14 with resin cement after the canals were acid etched and 14 with zinc phosphate cement after acid etching. After thermocycling, specimens were subjected to a straight-line tensile force. The posts cemented with resin cement had significantly higher tensile strength than those cemented with the two zinc phosphate cement treatments.
将12个预制桩用磷酸锌水门汀粘固于拔除的牙齿，14个在根管酸蚀后用树脂水门汀粘固，14个在酸蚀后用磷酸锌水门汀粘固。热循环后，对标本施加直线拉伸力。用树脂水门汀粘固的桩的抗张强度显著高于用两种磷酸锌水门汀处理粘固的桩。
