Dietary Nitrate Functional Gum Effect on Gingivitis and Heart Health

The purpose of the project is to characterize, in subjects with gingival inflammation, the effect of a prebiotic dietary nitrate formulated chewing gum on the oral microbiome. In order to assess this, gingival health and parameters related to vascular health are observed:

The study is testing the hypothesize that short term use of functional gum will have improved inflammatory measures of the gingiva and beneficial cardiovascular impact. The study hopes to discover if any observed changes to oral and cardiovascular measures may be associated to changes to oral microbiome composition.
