Translational and clinical periodontal research

Despite extensive research and increased knowledge of the pathogenesis of periodontitis, however, the disease is still diagnosed once connective tissue and bone destruction has occurred. One of the challenges for early detection of periodontal disease is its “silent” nature – the disease does not cause pain and progress unnoticed.

Periodontitis is a chronic inflammatory disease initiated by oral pathogens that activate host immune response and subsequently the production of inflammatory mediators and proteolytic enzymes, collectively contributing to destruction of tooth-supporting structures. This prevalent disease, affecting 38% of adult population, has also been implicated as a risk factor for various systemic diseases such as cardiovascular diseases, diabetes mellitus, obesity, and rheumatoid arthritis.

Our research aims are to generate the transcriptomic and taxonomic profiling of periodontitis and to identify new targets and diagnostic biomarkers facilitating early and specific diagnosis of the disease, which could lead to identification of individuals at risk of bone loss as well as early treatment/preventive strategies.

In addition, we investigate the potential relationship between periodontitis and systemic diseases such as rheumatoid arthritis and diabetes, as well as the effect of periodontal intervention on disease activity/severity.
