| 目的: 比较3种纤维桩树脂粘接材料的吸水性和溶解性,为临床应用提供实验依据。方法: 选取Paracore Automix、DMG Luxacore和可乐丽菲露DC core 3种双重固化树脂粘接剂,每种材料各制备5个试件,浸泡于蒸馏水中28d,通过测量浸泡前后的重量变化,计算材料的吸水值与溶解值。结果: ParaCore、Luxacore和DC core 3种粘接材料的吸水值分别为(20.13±0.97)µg/mm3、(17.67±1.46)µg/mm3和(18.29±2.77)µg/mm3,溶解值分别为(4.81±3.13)µg/mm3、(3.32±0.74)µg/mm3和(2.57±1.08)µg/mm3,ParaCore的吸水值和溶解值最大,与其他两种材料的吸水值与溶解值之间的差异均有统计学意义(P<0.05),DC core的吸水值和溶解值相对较低。结论: 三种纤维桩树脂粘接材料中DC core具有较好的稳定性;ParaCore的吸水值和溶解值最大,其远期力学性能较差,使用寿命缩短。 |

| Objective: To compare the water sorption and solubility of three resin cements for fiber post and provide experimental data for their clinical applycation. Methods: Three dual-curing resin cements were selected: Paracore Automix、DMG Luxacore and clearfil DC core. Five disk-shaped specimens made of each cement were prepared and immersed in distilled water for 28 days. After that, water sorption and solubility of each specimen were calculated according to the change of weight before and after water immersion and the volume of the specimen. Results: Water sorption values were(20.13±0.97)µg/mm3 for ParaCore, (17.67±1.46) µg/mm3 for Luxacore and(18.29±2.77)µg/mm3 for DC core. Water solubility values were(4.81±3.13) µg/mm 3 for ParaCore, (3.32±0.74)µg/mm3 for Luxacore and(2.57±1.08) µg/mm3for DC core. Both the water sorption and solubility of ParaCore were the maximum among these three cements. There were significant differences between both the water sorption and solubility of ParaCore and those of the other two materials(P<0.05). DC core showed low water absorption and solubility. Conclusion: Among three tested cements, DC core showed good stability, while ParaCore may has a decreased mechanical properties and reduced longevity as a consequence of high water sorption and solubility of this material. |
