摘要

昼夜节律是生物系统内自我维持的振荡,在多种生理过程中发挥着关键作用。大脑和外周组织中的昼夜节律机制可以独立振荡,也可以在外部刺激下同步/中断。牙釉质是一种形成牙冠外表面的矿化组织。增量雷齐乌斯线是成熟牙釉质易于观察到的微观结构,表明釉质的生成受昼夜节律的调节。牙釉质是由称为釉母细胞的釉质形成细胞形成的,在釉质形成过程中,这些细胞受到昼夜节律的调控和协调。本综述将首先探讨昼夜节律钟在调节釉母细胞和釉质形成过程中的关键作用。其中涉及多个生理过程,包括基因表达、细胞形态、新陈代谢变化、基质沉积、离子运输和矿化。接下来,将讨论昼夜节律紊乱对釉质形成的潜在不利影响。昼夜节律紊乱可直接导致釉质发育不全,这也可能是釉质发育不全症的潜在致病机制。最后,对这一领域未来的研究轨迹进行了推断。希望这篇综述能激发更深入的研究工作,并为制定预防牙釉质发育异常的新型治疗策略提供相关线索。

The circadian clock in enamel development

The circadian clock in enamel development

Circadian rhythms are self-sustaining oscillations within biological systems that play key roles in a diverse multitude of physiological processes. The circadian clock mechanisms in brain and peripheral tissues can oscillate independently or be synchronized/disrupted by external stimuli. Dental enamel is a type of mineralized tissue that forms the exterior surface of the tooth crown. Incremental Retzius lines are readily observable microstructures of mature tooth enamel that indicate the regulation of amelogenesis by circadian rhythms. Teeth enamel is formed by enamel-forming cells known as ameloblasts, which are regulated and orchestrated by the circadian clock during amelogenesis. This review will first examine the key roles of the circadian clock in regulating ameloblasts and amelogenesis. Several physiological processes are involved, including gene expression, cell morphology, metabolic changes, matrix deposition, ion transportation, and mineralization. Next, the potential detrimental effects of circadian rhythm disruption on enamel formation are discussed. Circadian rhythm disruption can directly lead to Enamel Hypoplasia, which might also be a potential causative mechanism of amelogenesis imperfecta. Finally, future research trajectory in this field is extrapolated. It is hoped that this review will inspire more intensive research efforts and provide relevant cues in formulating novel therapeutic strategies for preventing tooth enamel developmental abnormalities.
