Oral health and gastrointestinal neoplasia: Narrative review

Abstract

The oral cavity represents the gateway to the complex digestive system, so the knowledge of the exact mechanisms that link them is vitally important. Recently, oral and dental pathologies have been studied as potential risk factors for pathologies linked to lifestyle habits. Therefore, it could be considered as an interesting preventive way. We conducted a narrative review with a thorough bibliographic search on MEDLINE and SCOPUS, including international studies related to oral healthcare and gastrointestinal neoplasms, published between 2015 and 2020. The primary aim of this revision is to analyze the association between oral healthcare and carcinogenic gastrointestinal processes, providing a possible future preventive strategy for dental care. Moreover, we intend to raise awareness about the importance of oral healthcare as a new paradigm and study variable in the global health care system.
