Abstract
The purpose of this study was to examine the potential effects of restorative dental materials on the kidneys and liver tissues of rats. The histological, immunohistochemical and biochemical analyzes were conducted using 32 adult female Wistar albino rats classified into 4 groups (n=8): Control group, Dental amalgam group, Resin composite group, and Glass-ionomer group. The dental materials mentioned were put on the backs of the rat heads and kept there for 8 weeks. After humanely euthanizing rats, kidney and liver tissue was removed by necropsy, and Hematoxylin&Eosin and NF-κB p65 staining methods were used. In addition, glutathione, superoxide dismutase, lipid peroxidation and catalase levels have been identified. Immune-positive cells were higher in all sample groups than in the control group. Renal and hepatic degeneration has also been found in dental filling content groups. All biochemical findings revealed oxidative stress in all groups with the exception for control group. The three dental filling products have significant cytotoxic effects on the kidney and liver tissues, and may have been linked with oxidative stress in the tissues of the kidney and liver.
