Imagine a brave expedition to Mars on a long-term mission, and then gradually find that their teeth are becoming weaker, chewing food quickly becomes painful, eating every day becomes a pain, and fulfilling their duties also changes. more difficult…
Could this worrying situation happen? We didn’t know that, and that’s the problem, so far we’ve known that microgravity erodes bone mass, shrinks muscles, deteriorates vision, and has other harmful effects, and teeth are the most prone to problems.
We now know that microgravity erodes bone mass, shrinks muscles, deteriorates vision, and has other harmful effects, and teeth are the most prone to problems.
A study published in the journal JDR Clinical and Translational Research in April said that during long-duration space missions to the moon and Mars, assessing and analyzing dental health risks is critical to avoiding dental emergencies in settings that do not support appropriate treatment.
Study authors Moussa Goldsmith and S.V. Comarova has systematically analyzed published reports on the effects of spaceflight on teeth and facial bones. To date, they have identified 32 dental and facial bone health risks, 26 of which were in rodents. In animals, only 6 cases have occurred in humans. Unfortunately, these experiments were usually observed for a short period of time, and most of the experiments were conducted in the 20th century and lasted less than 3 weeks. Crucially, , so far no study has explored the effects of spaceflight on human teeth.
The researchers analyzed all rodent experiments and found that there were no statistically significant differences in tooth size and dentin thickness between space and Earth-fed lab animals, both on the same diet, but the findings varied. Dentin is a calcified tissue that makes up a large part of a tooth and lies beneath the outer layer of enamel.
A number of factors complicate the interpretation of the findings for the significance of human space travel. First, there were significant differences in the diets of the rodents in the study, with some mice being fed a mushy diet, others being fed rice fortified with nutrients, and some Mice were fed food bars developed by NASA. In addition, the experimenters only observed the rodent incisors, the front teeth of the mouth, and did not make a comprehensive observation of the oral teeth. In fact, rodent incisors are very different from human incisors. The former is constantly growing, enamel and Dentin is formed by the continuous deposition of ameloblasts and odontoblasts.
The study suggests that we really need long-term studies on the effects of spaceflight on human teeth, which will help avoid any potential problems that might arise from long-term travel to the moon or Mars, perhaps through diet (i.e. eating crispier, harder Food) or drugs (specialized toothpaste) can solve this problem, and researchers have now proposed a theoretical advanced space dental surgery treatment plan.
Former Soviet cosmonaut Yuri Romanenko allegedly suffered a toothache while on a mission on the Mir space station and was forced to endure it for two weeks before returning to Earth as planned .
We don’t want this to happen again. NASA now requires astronauts to maintain good oral hygiene before entering space, but regular brushing and flossing may not reduce the adverse effects of microgravity.
The researchers concluded that a specific understanding of the effects of microgravity … is important for understanding the risks of space travel to oral health and for developing strategies to mitigate this risk as humans continue to explore the universe.
