Pulpal histological response after crown cementation with a glass ionomer luting agent was evaluated and compared with the response to a polycarboxylate cement or a varnish plus zinc phosphate cement. Pulpal histological response was evaluated on teeth that had full crowns cemented with the test luting agents 3, 10, and 56 days after cementation. No statistically significant differences were found in pulpal histological response between the materials tested during all periods. These findings suggest that factors other than pulpal inflammation are contributing to the reported hypersensitivity after cementation associated with glass ionomer luting agents.
评估了用玻璃离子水门汀粘固剂进行冠修复粘固后的牙髓组织学反应，并与使用聚羧酸锌水门汀或清漆加磷酸锌水门汀的反应进行了比较。在粘固后3天、10天和56天，对用测试粘固剂粘固全冠的牙齿进行牙髓组织学反应评估。在所有时间段内，测试材料之间的牙髓组织学反应未发现统计学上的显著差异。这些发现表明，除了牙髓炎症之外，还有其他因素导致了与玻璃离子水门汀粘固剂相关的粘固后超敏反应的报道。
