Science Results for Everyone
Will the tooth fairy visit you in space? This investigation determined that significant changes occur during spaceflight in the tissue around teeth, which can affect immune response and increase the risk of inflammation and disease. Crewmembers took samples of their saliva and from the surface of a tooth for laboratory analysis back on the ground, where researchers observed decreases in beneficial microflora – bacteria and other living organisms – and increases in harmful microflora. The results will be used to improve dental care to protect crewmembers, and people on Earth, against periodontal disease.
