RESUMO
OBJECTIVE: The aim: The study of the possibilities of oxidase-antioxidant system indicators regulation at patients with periodontitis under the influence of complex treatment. PATIENTS AND METHODS: Materials and methods: 36 healthy and 125 patients with chronic and exacerbated periodontitis of primary (22 and 21), I (21) and II (20) degrees were examined.Indicators of lipid peroxidation and antioxidant protection (levels of diene conjugates and malonic dialdehyde, catalase activity and transferrin iron saturation, ceruloplasmin activity) in the blood serum were studied before, 6 and 12 months after the appointed treatment. Initial periodontal therapy and a paste developed by us (spirulina microalgae powders and silica enterosorbent taken in equal amounts and 0.05% chlorhexidine bigluconate) for applications and instillations were exogenously used in the complex treatment. Spirulina tablets were prescribed per os as well. RESULTS: Results: All patients exhibit elevated levels of diene conjugates and malonic dialdehyde, decreased catalase activity and transferrin iron saturation as well as an increased ceruloplasmin activity, especially pronounced at stages I and II (p1≤0.01-0.001). Treatment contributed to long-term and reliable (p2<0.05 - 0.001) regulation of the studied parameters: reduction of diene conjugates and malonic dialdehyde, ceruloplasmin activity and increased catalase activity and transferrin iron saturation. All indicators differed slightly from the norm during the year (p1>0.05), and complete normalization of most of them lasted six months. At the same time clinical stabilization of periodontitis was reached. CONCLUSION: Conclusions: Indicators of the oxidase-antioxidant system in patients with periodontitis are significantly altered and indicate their participation in the pathogenesis of the disease. Complex treatment was able to almost completely normalize them within six months, but a year later the difference between the obtained indicators with data in healthy people was insignificant (except for ceruloplasmin). Clinical stabilization was achieved in all patients.
