Hypobaric chamber for the study of oral health problems in a simulated spacecraft environment
A hypobaric chamber was constructed to house two marmo-sets simultaneously in a space-simulated environment for periods of 14, 28 and 56 days which coincided with the anticipated Skylab missions. This report details the fabrication, operation, and performance of the chamber and very briefly reviews the scientific data from nine chamber trials involving 18 animals. The possible application of this model system to studies unrelated to oral health or space missions is discussed.

Effects of SMEAT on the oral health of crewmen (DTO 71-2)
The oral health status of three astronauts was monitored before, during and after a 56-day simulation of the Skylab mission. Laboratory and clinical parameters which are considered to be ultimately related to dental impairments were evaluated. The most notable changes were observed in increased counts of mycoplasma and S. mutans, decreased counts of enteric bacilli, decreased saliva flow rates, increased secretory IgA and salivary lysozyme levels, and increased clinical scores of dental plaque, calculus and inflammation.
