Research project

The Role of Prebiotics and Probiotics in the Oral Microbiota

Abstract: It is well known that prebiotics and probiotics alter the human gut microbiota, which is linked to positive health outcomes. The aim of this systematic review was to evaluate whether probiotics and prebiotics have significant changes in the oral microbiota. This research examines and analyzes journal articles that discuss prebiotics and probiotics and their effects in the oral microbiota. PubMed and Academic Search Premier databases were used to search articles based on numerous criteria. 18 articles were found, and four studies of the 18 were used to analyze the results. Of the four studies, two found a significant reduction in streptococci mutans when a type of probiotic was taken. The other two studies, however, didn’t show a significant effect or a shift in the oral microbiota composition. Overall, more studies need to be done on the effect of probiotics and prebiotics in the oral microbiota, especially since it’s currently suspected that changes in the oral microbiota may decrease risk for chronic diseases including cardiovascular disease and cancer, and oral diseases such as dental caries and gingivitis.
