An open, prospective study was conducted in which 37 patients with periodontal disease (PD) and duodenal ulcer (DU) in the scarring phase with fixed metal dentures (FMD) and fixed metal-ceramic dentures (FMCD) participated. To determine the treatment effectiveness, two groups of patients were formed: the 1st group (16 people), which in addition to traditional therapy of PD, received vitamin E 100 mg once a day for 30 days; Group 2 (21 people) additionally received reduced L-glutathione (250 mg) with astaxanthin (40 mg) (Hepaval ASN) 1 capsule 2 times a day for 30 days. Complex therapy of patients with PD on the background of DU with fixed dentures with the inclusion of GSH and astaxanthin for a month helped to reduce the intensity of lipid peroxidation (LPO), oxidative modification of proteins (OMP) and endotoxicosis, reducing the activity of PD, which can be considered a preventive measure to prevent further loss of teeth and the need for prosthetics.
