Microbiome Effects of Extended Use of MI Paste in Elderly Removable Denture Wearers

Sterile swabs will be used to collect plaque from under the subject's upper denture (when the denture is removed) and the subject's mouth tissues. This will be used for genomic DNA, bacteria analysis, and fungus analysis. Subjects will also apply 1 cubic centimeter of MI Paste to the fitting surface on a daily basis for 7 days. Afterward, subjects will return to the clinic for another sterile swab to be collected.
