摘要
随着载人航天技术的快速发展,太空任务中的微重力环境对航天员口腔稳态的影响日益受到关注。本文综述了微重力环境下口腔稳态失衡的最新研究进展,重点探讨了微重力对颌面部软硬组织(牙槽骨、牙周组织、唾液腺及咀嚼肌),口腔微生物组以及颌面部干细胞的影响。微重力会导致牙槽骨流失、牙周炎症状加重、唾液成分改变及微生物组失衡,进而增加龋病、牙周炎等口腔疾病的风险,但可促进颌面部干细胞的增殖与分化。通过综述微重力对口腔稳态影响的研究进展并展望未来研究方向,为航天员口腔健康防护提供理论依据。
With the rapid development of manned spaceflight technology,the impact of microgravity environment on the oral homeostasis of astronauts in space missions has attracted increasing attention.This article reviewed the latest research progress of microgravity on oral homeostasis imbalance,focusing on the effects of microgravity on maxillofacial soft and hard tissues(alveolar bone,periodontal tissues,salivary glands and masticatory muscles),oral microbiome,and maxillofacial stem cells.Microgravity can lead to alveolar bone resorption,aggravation of periodontitis,alterations in saliva composition and microbiome imbalance,which in turn increases the risk of oral diseases such as caries and periodontitis,but it can promote the proliferation and differentiation of maxillofacial stem cells.Further,this review outlines prospective research directions of the oral health protection of astronauts.
