An in vitro study with cultured fibroblast-like cells of the pulp was used to assess the biological tolerance of three lining cements based on glass ionomers and two hard liners containing calcium hydroxide. The results indicate that strong cytotoxic components of all g.-i. lining cements tested can be eluted even after hardening for 48 hours. In contrast, the two liners based on calcium hydroxide proved to be of greater biocompatibility after the same hardening period. Therefore, use of calcium hydroxide liners is recommended for placement in deep cavities near the pulp.
一项使用牙髓培养的成纤维细胞样细胞进行的体外研究，用于评估三种基于玻璃离子体的衬层粘固剂和两种含氢氧化钙的硬衬层的生物耐受性。结果表明，即使在硬化48小时后，所有测试的玻璃离子体衬层粘固剂的强细胞毒性成分仍可被洗脱。相比之下，在相同的硬化期后，两种基于氢氧化钙的衬层被证明具有更高的生物相容性。因此，建议在靠近牙髓的深龋洞中使用氢氧化钙衬层。
