This study compared the pulpal responses to two innovative semihydrous glass ionomer luting cements (STA and ZIN) with those previously obtained for a conventional anhydrous glass ionomer luting cement, Aquacem. ZIN contained zinc oxide in the formulation. The study was conducted according to the BSI (1989) recommendations for testing restorative materials in vivo. ZIN was associated with minimal pulpal changes and microbial microleakage, and differed little from the control material, Kalzinol. The pulpal response to STA was similar to that observed for Aquacem, but was associated with less microbial microleakage. The statistical model demonstrated a significant association between bacterial presence within the experimental cavity and pulpal inflammation. The closer that bacteria were to the pulp, the more severe was the ensuing inflammation.
本研究比较了两种新型半水玻璃离子水门汀（STA和ZIN）与之前一种传统无水玻璃离子水门汀Aquacem的牙髓反应。ZIN的配方中含有氧化锌。该研究是根据英国标准协会（1989年）关于体内测试修复材料的建议进行的。ZIN与最小的牙髓变化和微生物微渗漏相关，与对照材料Kalzinol差异不大。对STA的牙髓反应与Aquacem相似，但微生物微渗漏较少。统计模型表明，实验窝洞内细菌的存在与牙髓炎症之间存在显著关联。细菌距离牙髓越近，随之而来的炎症就越严重。
