[Dental caries resistance under conditions of a space flight].
The maxillodental status of aeronauts attracts special interest of scientists and causes apprehensions of physicians and scientists of countries with aeronautic industry because of long duration of space missions. Some scientists consider that the realization of mission to Mars can lead to development of multiple dental caries in aeronauts. The aim of this study was to study the effects of space mission factors on the resistance of hard dental tissues and remineralizing activity of the saliva in a simulation experiment. The results demonstrated dynamic changes in the studied parameters under the effect of space mission factors; based on these results, we determined the criteria for selection of candidates for prolonged experiments and space missions.
