Cellular Al accumulation has been shown to alter iron metabolism and induce peroxidative injury. Therefore antioxidants could potentially reduce or prevent peroxidative injury in Al-loaded cells. To test this hypothesis we assessed the effect of the antioxidants N-acetyl cysteine (NAC), catalase, superoxide dismutase (SOD), and tetramethylpiperidine 1-oxyl (TEMPO) in abrogating Al-associated cell...
Previous in vitro studies on the cytotoxicity of eight dental restorative materials including composites, compomers, resin-modified glass ionomer cements and glass ionomer cements have demonstrated a depletion of intracellular glutathione in gingival fibroblasts incubated with eluates of these materials and a protective effect of N-acetylcysteine. In the present study, we investigate the effects of...
