Aeronautics in dentistry: Navigating oral health challenges in zero gravity

Abstract

Space, an expansive environment beyond Earth’s atmosphere, poses challenges for astronauts and spacecraft due to microgravity and radiation. These conditions disrupt saliva production, alter oral microbial composition, and challenge hygiene practices, leading to oral health concerns such as dental caries, periodontal diseases, and discomfort. Astronauts also face risks such as masticatory muscle atrophy and oral cancer during extended space missions. Thus, comprehensive dental care in space is crucial for astronaut well-being and overall health as humanity explores farther into space. This review delves into these challenges, exploring strategies to maintain optimal oral health during space travel and advancements in dental practices for astronauts on prolonged missions.
