Abstract
BACKGROUND: Biocompatibility of repairing materials is an important factor for clinical effects.OBJECTIVE: To evaluate the material biocompatibility in oral repair by analyzing different expressional levels of urokinase-typeplasminogen activator (uPA) and plasminogen activator inhibitor-1 (PAI-1) of human gingival fibroblasts (HGFs) in four types ofmetal extractions.METHODS: Healthy gums were obtained to cultivate HGFs. Levels of PAI-1 and uPA were examined by immunofluorescenceand enzyme linked immunosorbent assay (ELISA) detection after different procedures: Co-Cr, Ni-Cr, Ti and rhotanium metalextractions. HGFs with no treatment served as controls.RESULTS AND CONCLUSION: ELISA results showed an increase in uPA levels after treatment with Co-Cr and Ni-Cr metalextractions. Immunofluorescence detection and electron microscope revealed deep-stained and even-distributed cytoplasm aftertreatment with Co-Cr and Ni-Cr, indicating PAI-1 levels were increased. There were changes in the levels of uPA and PAI-1 aftertreatment with Ti and gold alloy metal extractions. Biocompatibility of Ti and rhotanium is better than that of Co-Cr and Ni-Cr.关键词
