Abstract

A material is considered as biocompatible when it does not harm nor create toxic reactions or systemic side effects. Most of reactions caused by dental materials are of allergic type, with symptoms pointed out at the oral mucosa level or cutaneous tissue level. For saliva and dental tissues media, which a dental restoration comes into contact it is of extremely importance the proper knowledge of the changes which can occur in time at the materials level. The present study assays the biocompatibility of six samples of dental alloys used in metal-fused-to-ceramic technology, three based on NiCr and three based on CoCr. All biocompatibility assays were performed on an osteoblast-like cell line, phenotypically close to osteoblasts (MNNG-Human Osteosarcoma cell line - HOS).
