Identifying Deceased American Service Members; Prisoners of War (POW) and Missing in Action (MIA)
This study is collecting a persons wisdom teeth/third molars (teeth located near the back of the mouth) from people across the United States. The study team will use the teeth to learn more about the life history of people from different places in the country. The information may help identify American military prisoners of war and missing in action. (IRB#: IRB_00139648)
Reducing Harmful Bacteria in the Mouth with Twice-Daily Tooth Brushing
This study will test a new toothpaste that may help reduce harmful bacteria in the mouth, specifically Streptococcus mutans (S.mutans), which is known to cause cavities in teeth. The new toothpaste targets these harmful bacteria while supporting the growth of good bacteria that help keep the mouth healthy. The study wants to see if the daily routine with the toothpaste lowers the levels of S. mutans and improves the overall balance of bacteria in the mouth, which may help reduce the risk of cavities. Participants in this study will brush their teeth twice a day with the assigned toothpaste for 28 days. Being in the study requires attending 3 in-person visits at the study clinic.
