title: Experimental study on the biocompatibility of lining cements based on glass ionomer as compared with calcium hydroxide.
abstract: 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.
