Abstract: Reactive oxygen species and antioxidant status in periodontal
diseases and periodontal-related pathologies is an item of growing interest.
Immunohistochemical approach may be usefully employed in the study of soft
tissues affected by periodontal disease, giving valuable information on tissue
morphology and vascular proliferation that depends directly on the inflammatory
state. In order to study CoQ_{10} and vitamin E content
in healthy gingiva and in gingivitis a new adaptation to previously published
methods for their determination was adopted. During gingivitis tissue displayed a large inflammatory infiltration
in the lamina propria and a VEGF positive squamous epithelium. The inflammatory
infiltration consisted mainly of lymphocytes, plasma cells and neutrophils.
Vitamin E dramatically decreased and CoQ_{10} remained
unchanged despite the increased amount of cells present in the periodontally
affected tissues, indicating that continuous oxidative stress which occurred in
these structure affected the antioxidant pattern of the tissue.
