The role of oral health in gastrointestinal malignancies

Many studies have shown a connection between poor oral health and a number of systemic diseases. Recent studies have demonstrated an association between poor oral health and the oral microbiota to carcinogenesis. This review article will focus on studies that link oral dysbiosis, periodontal disease, and specific oral microorganisms to gastrointestinal malignancies. These studies provide some insight and understanding of the role of the oral microbiome in carcinogenesis. Understanding how the oral microbiota is related to carcinogenesis and gastrointestinal malignancies could lead to identifying biomarkers and provides future treatment modalities. More research in this area would be beneficial to the diagnosis and treatment of patients with gastrointestinal malignancies.
