Periodontal disease is the human population's most common oral condition; it can cause loss of teeth if periodontitis is not treated in its initial stages. Medical measurements are the basis for the diagnosis of periodontitis. Actually, however, other diagnostic and tracking solutions are being explored with the development of technology. In reality, where different biological fluids were used as the source of the sample, various types of biomarkers were evaluated. We will try to summarize current biomarkers at various stages of periodontitis and compare the periodontal biomarkers tested so far and their utility in periodontitis diagnosis and monitoring.
