Research Abstract

The aim of this study examined the effects of dysfunctional mastication such as occlusal interference and soft-food diets on oxidative stress in the brain, and the relationship between these effects and dopamine (DA) levels. Electron spin resonance (ESR) studies using the nitroxyl spin probe 3-methoxycarbonyl-2,2,5,5-tetramethylpyrrolidine-1-oxyl directly demonstrated a high level of oxidative stress in the rat brain due to dysfunctional mastication. In addition, we confirmed that DA directly reacts with reactive oxygen species such as hydroxyl radical and super oxide in vitro. These observations suggest that dysfunctional mastication enhances oxidative stress, which leads to oxidation and a decrease in the release of DA in the hippocampus of rats.
