Immunological Insights on Pathogenic Connections between Hepato-Digestive Disorders and Periodontal Conditions

The oral cavity is an integral part of the digestive tract and thus significant diseases, including periodontitis, can have an important impact on the normal nutritional functions of the body. Certain diseases of the hepato-digestive system have an inflammatory component, such as chronic hepatitis, fatty liver disease, or gastric cancer. This inflammatory reaction is mainly driven by pro-inflammatory chemokines. This is also the case for periodontitis, a condition characterized by the inflammation of the supporting tissues of teeth. Thus, significant pathogenic connections mediated by pro-inflammatory chemokines could exist between periodontitis and diseases of the hepato-digestive system.
