The impact of periodontal infections on systemic diseases. An update for medical practitioners.

Oral health status is an integral component of a general health and well-being of an individual. Knowledge about the link between periodontal disease and systemic diseases are growing rapidly. Increasing evidence is available from many investigators to indicate periodontitis as a risk factor for cardiovascular diseases, diabetes mellitus, low birth weight infants and pulmonary diseases. Both epidemiologists and researchers in oral microbiology have contributed significantly to the new paradigm of periodontal disease. Although additional studies are needed to determine the mechanisms by which such associations exist; available research clearly demonstrates that oral diseases and conditions are not only markers for underlying health problems, but also important determinants influencing the development and management of adverse chronic health conditions. Physicians and dentists should be aware of this link and provide treatment that will greatly benefit the patients. A review of the relationship between periodontal infections and its possible impact on systemic diseases is discussed.
