The research goal is to determine the clinical pathogenetic efficacy of Cycloferon liniment in the combined therapy of periodontitis in patients with subclinical stage of HIV-infection. Medical examination and treatment of 40 patients has been carried out. It is established that use of liniment Cycloferon in the combined treatment of patients with subclinical stage of HIV-infection allows to accelerate process of normalization of lipid peroxidation parameters and antioxidant potential of blood and to decrease infection (herpes symplex virus I, Candida albicans, staphylococcus aureus) in par-odontal recess and evidence of local inflammation. The considered method of therapy has been proved to improve convalescence period and to decrease frequency of parodontitis recurrence
