Lipid peroxidation and antioxidant status in patients with
periodontitis.
Panjamurthy K, Manoharan S, Ramachandran CR
Cell Mol Biol Lett. 2005; 10(2): 255-64
Our aim was to assess the degree of oxidative stress in patients with
periodontitis by measuring their levels of thiobarbituric acid reactive
substances (TBARS), enzymatic antioxidants (superoxide dismutase (SOD),
catalase (CAT), glutathione peroxide (GSHPx)), and non-enzymatic
antioxidants (vitamins E and C, reduced glutathione (GSH)). This study
was conducted on 25 adult chronic periodontitis sufferers who were
patients in Rajah Muthiah Dental college and Hospital, Annamalai
University. The levels of TBARS and non-enzymatic antioxidants, and the
activities of enzymatic antioxidants in the patients' plasma,
erythrocytes and gingival tissues were assayed using specific
colorimetric methods. The periodontitis sufferers had a significantly
higher TBARS level than the healthy subjects. In the plasma,
erythrocytes, erythrocyte membranes and gingival tissues of the
periodontitis sufferers, enzymatic antioxidant activities were found to
be significantly higher, whereas the levels of non-enzymatic
antioxidants were significantly lower (except for reduced glutathione
in the gingival tissues) relative to the parameters found for healthy
subjects. The disturbance in the endogenous antioxidant defense system
due to over-production of lipid peroxidation products at inflammatory
sites can be related to a higher level of oxidative stress in patients
with periodontitis.
