Summary

Periodontitis is a chronic inflammatory disease characterized by both dysbiosis of oral microbiota and proinflammatory events involving both cells and mediators from innate and adaptive immunity. These events lead to chronic inflammation of periodontal soft and hard tissues sharing many features with other chronic inflammatory diseases. These events lead to chronic inflammation of periodontal soft and hard tissues sharing many features with other chronic inflammatory diseases. Chronic inflammation is driven by various mediators, of which a significant part is attributed to the interactions within cytokine networks. While proinflammatory cytokines, including interleukin (IL) -1α, IL-1β, TNF-α, IL-6, and IL-17, contribute to acute and chronic inflammation and tissue injury, a second group with antagonist effects is formed by cytokines such as IL-10

Detailed description

Diagnosis of Periodontitis represents the backbone of a successful periodontal treatment since the entire treatment plan, prognosis, and maintenance directly depend on the quality and precision of periodontal diagnosis. Since periodontal diagnostics is still based on clinical and radiological parameters providing limited therapeutic guidance, biomarkers have been introduced for the first time within the new classification of periodontal and peri-implant conditions as a first step towards the adoption of precision medicine concepts in periodontology. Saliva, as part of oral fluids, is an optimal biological fluid that contains locally and systemically derived mediators of periodontal disease (proteins, genetic/genomic biomarkers such as DNA and mRNA, and various metabolites that originate from the host and the bacteria) to serve as the diagnostic tool for periodontitis. The collection of saliva is safe, non-invasive, and simple, and saliva can be collected repeatedly with minimum discomfort to the patient. Single biomarker detection may not be effective enough for accurate diagnoses without false-positive or false-negative results. Periodontitis is a disease that involves complex interactions between bacteria and the host immune system. The combination of the host and bacteria-derived biomarkers, which reflect inflammation, soft tissue destruction, and bone destruction together, may be helpful in the diagnosis
