[Lipid peroxidation in persons with chronic odontogenic foci of infection].

In 86 patients with chronic granulomatous and granulating periodontitis in the absence of other pathology the lipid peroxidation products levels were increased as indicated by accumulation of malonic dialdehyde and diene conjugates in the whole blood. The relative content of disulphide groups in the red blood cells was increased and that of sulfhydryl groups decreased. The findings correlate with those detected in granulomas.
