The oral cavity presents a great diversity of microorganisms. The buccal microbiota is normally in harmony with the host, but in abnormal conditions it has the potential to generate serious oral and systemic infections. The present study aimed to verify the importance of oral microbiota in the health-disease process. A review of the literature was carried out by searching the databases: LILACS, BBO, Scientific Electronic Library Online (Scielo) and Virtual Health Library (VHL). The criteria for inclusion were: scientific articles dealing with the subject, published between 2000 and 2018 in Portuguese, English and Spanish. The results showed that the oral microbiota is influenced by temperature, pH, presence of oxygen, availability of nutrients and defense mechanisms of the host. When deregulations of these parameters occur the microbiota is altered, which triggers colonization by pathogens. Correlated systemic infections (cardiopathies and respiratory infections) present direct and bidirectional relationships, where the outcome is almost always death. However, there is a need for more detailed research to clarify this real influence.
