[Iron in oral cavity fluid in gingival inflammation].

In parodontosis, iron levels are higher in the human gingival fluid and mixed saliva. The free iron-binding capacity of saliva is also increased. In gingivitis, higher levels of iron and free binding capacity are less evident. The increased levels of iron activate free radical oxidation in gingival tissue and improve microbial metabolism. This all contributes to the deterioration of a pathological process in the gingiva.
