概括
ортодонтическая力触发早期免疫反应和DNA损伤在牙纸,随后的组织修复和牙形成28天后. 大和下牙对这种力有不同的反应.
科学领域:
- 基因组学和分子生物学
- ортодонтика和牙科研究.
- 组织工程是组织工程.
背景情况:
- 矯正力 (OF) 在牙髓 (DP) 內產生複雜的生物反應.
- 了解DP中的时间基因表达变化对于优化正义牙科治疗至关重要.
- 大牙和下牙之间DP响应的变化尚未完全阐明.
研究的目的:
- 在正牙力 (OF) 下分析人类前牙肉质 (DP) 的基因表达特征. 在7日和28日.
- 为了比较大牙和下牙之间的DP基因表达反应.
- 确定参与DP适应OF的关键生物途径和监管网络.
主要方法:
- 来自接受正牙治疗的健康患者的人类先牙在7天或28天内接受了受控的OF (50-100克).
- 从牙纸组织中提取总RNA,并使用RNA测序 (RNA-seq) 进行分析.
- 使用严格的统计值 (FDR <0.05,折叠变化≥1.5) 确定差异表达基因 (DEG),然后进行功能丰富分析.
主要成果:
- 经过7天的OF,DP表现出显著的免疫反应,缺氧,DNA损伤和表观遗传调节.
- 在28天后,DP显示了细胞粘附,迁移,组织组织和修复过程的证据.
- 部DP显示最小的变化 (免疫反应在7天,修复在28天),而下部DP显示DNA损伤和表观遗传变化在7天,回到基线28天.
结论:
- 对OF的早期DP反应涉及免疫反应,缺氧和DNA损伤,在28天后过渡到组织修复和牙形成.
- 大牙和下牙之间DP反应存在显著差异,可能是由于血管化和骨密度变化.
- 这些发现提供了对基因调节机制的关键见解,这些机制控制了DP适应正力,为临床实践提供了信息.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
