Salivation and some biochemical indices of oral liquid were studied in 22 patients with chronic catarrhal gingivitis (CCG) before and after treatment with ointment consisting propolis. Reduction in salivation speed, increase of albumen contents activity of proteases and malonic dialdehyde (MDA) in oral liquid were determined at CCG. The application of the elaborated treatment ointment consisting propolis normalizes salivation, reduces the level of albumen, activity of proteases, concentration of MDA and increases activity of catalase and antioxidant-prooxidant index (API) in the examined patients.
