For objectification of the clinical research of the periodontal tissues, we used indicators such as the periodontal index, papillary-marginalalveolar index and the index of Ketze. For aexact determination of the intensity of the inflammatory process
used Schiller-Pisarev trial. To measure the depth of periodontal pockets also held X-ray examinations. It was found that a significant activation of lipid peroxidation and reduced antioxidant defense observed in patients with severe CGP on the background of hypothyroidism. It is shown that thyroid dysfunction occurs pronounced activation of the immune system, manifested by increased levels of cytokines in the serum. The highest concentration of TNF, IL-1 and IL-4 were detected in patients with moderate CGP thyroid hypofunction.
