Abstract

Fluoride release from six light-activated restorative materials, including two resinmodified glass-ionomers, two composites, and two compomers, was evaluated and compared with one conventional acid-based glass-ionomer cement. The amount and rate of release varied among the tested materials. Both resin-modified glass-ionomers and the conventional acid-base glass-ionomer cements released more fluoride then the composites and compomers (p < 0.05). Additionally, composite materials released less fluoride than compomer materials (p < 0.05). Release of fluoride by the tested materials showed a significant decrease after all the tested time intervals.

摘要

评估了六种光固化修复材料（包括两种树脂改性玻璃离子体、两种复合树脂和两种聚酸改性复合树脂）的氟释放情况，并与一种传统的酸碱玻璃离子水门汀进行了比较。测试材料之间的释放量和释放速率各不相同。树脂改性玻璃离子体和传统酸碱玻璃离子水门汀释放的氟均多于复合树脂和聚酸改性复合树脂（p < 0.05）。此外，复合材料释放的氟少于聚酸改性复合树脂材料（p < 0.05）。在所有测试时间间隔后，测试材料的氟释放均显著减少。
