Effect on Oral-cardio Health From Dietary Nitrate Loaded Functional Gum
Study Details
Study Description
Brief Summary
The purpose of this research is to determine the effects of a chewing gum containing dietary nitrate to your gingival and heart health. Dietary nitrates are commonly found in leafy vegetables and beets. The information learned from the study may help us further understand the interconnection of oral health and heart health. The study is looking for individuals who present with mild to moderate gum irritation or bleeding.
In the study participants will be randomized into either a group that will use a chewing gum containing dietary nitrate, or use a placebo chewing gum during a three-week period.
Participants in the study will have a simple gingival exam, x-rays if needed, and small samples of saliva and blood collected. All participants will also undergo a routine tooth cleaning. Participants will be asked to breathe in a tube to sample the levels of nitric oxide. Finally, participants will have their heart health measured with a device that is like a blood pressure cuff.

Detailed Description
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, we will observe gingival health and parameters related to vascular health:
We are testing the hypothesize that short term use of functional gum will have improved inflammatory measures of the gingiva and beneficial cardiovascular impact. We endeavor to discover if any observed changes to oral and cardiovascular measures may be associated to changes to oral microbiome composition.
