Collection of Dental Plaque and Saliva for Studies of Bacterial Colonization of Teeth
Collection of Dental Plaque and Saliva for Studies of Oral Microbial Colonization
This study will explore how bacteria colonize human teeth and how this process changes over the lifetime of individuals. It will include an investigation of transmission of bacteria that initiate colonization between adults and from adults to infants.
Selected NIH scientists and members of their immediate families, including infants, are eligible for this study. Participants provide a small sample of saliva and a sample of bacteria collected by rubbing a cotton swab over the surfaces of the lower four incisors. Adults collect and submit their own specimens; a dentist collects specimens from children.
