Periodontal diseases and inflammatory diseases such as arthritis show similar clinical pathologies such as connective tissue deterioration and bone destruction. They carry the risk of being seen together and the possibility of mutual influence. It is important whether these patients have a difference in cytokine profile from individuals who do not have the disease. In the literature, it has been determined that pro and anti-inflammatory cytokines, which are involved in the pathogenesis of periodontitis, are also involved in the pathogenesis of juvenile idiopathic arthritis (JIA). Cytokines play an undeniable role in the pathogenesis of both diseases. The cytokine profile in periodontal disease is distinctly similar to that of rheumatoid arthritis (RA). As in RA, the level of pro-inflammatory cytokines such as interleukin-1 beta (IL-1β) and tumor necrosis factor-alpha (TNF-α) increase in periodontal disease. Again, it is stated that oxidative stress assessment is an important factor in evaluating the development of the disease. Saliva evaluation can be made with new oxidative stress markers that can be used in this sense.~On the subject of the proposed thesis; It is to determine the profile of dental and periodontal health in a specific group in terms of biochemical and microbiology using different body fluids together with clinical findings and has an interdisciplinary character. Aimed to be done in the planned thesis;~It was aimed to evaluate the dental and periodontal health of patients with newly diagnosed JIA and healthy-periodontal problems with cytokines from saliva and oxidative stress markers non-invasively, and thus, to determine the markers' evaluability in terms of markers in determining the state of inflammation among individuals with and without the disease.
