Role of the biological environment of the oral cavity in differential diagnosis of chronic periodontitis and dental peri-implantitis

The relevance of the study is caused by the need to search for metabolic criteria for inflammatory destruction of bone tissue. Purpose of the study: differential diagnosis of chronic periodontitis and dental peri-implantitis according to metabolic criteria of the biological environment of the body (oral fluid). The study included patients who were divided into 3 groups: 35 people with chronic periodontitis (group 1); 30 - with dental peri-implantitis (group 2); 20 - control group. The authors studied the protein and mineral metabolism of oral fluid. The authors conducted a study of the biological environment and found that the concentrations of total protein in all groups were not statistically different. However, total albumin concentration was lower in patients with dental peri-implantitis compared to controls and chronic periodontitis (p
