Abstract

In order to investigate the biocompatibility of base metal alloys in dental prosthesis, the 3 types of Ni-Cr alloys and the 3 types of Co-Cr alloys were collected and each alloy was extracted in the culture medium. L-cells derived from the subcutaneous tissue of mouse and extracted medium were cultivated. The relative growth rate of L-cells in the tissue culture was calculated with N-R assay. The obtained results were as follows: 1. In the case of the Co-Cr alloys tested, its cytotoxicity proved weak. 2. In the case of the Ni-Cr alloys tested, there was no significant degree of cytotoxicity, especially 25% Victory was proved noncytotoxicity.
