概括
与同龄人相比,裂唇 (CL±P) 的儿童表现出延迟的牙年龄. 一种特定的基因变异 (TGFB1中的SNP rs4803455) 影响了没有CL±P的儿童的牙年龄.
科学领域:
- 遗传学 是一个遗传学.
- 儿科牙科 儿科牙科
- 发展生物学 发展生物学
背景情况:
- 带有或没有的非综合性裂唇 (CL±P) 可以影响儿童的牙发育.
- 了解这些发育变化及其遗传基础对于有针对性的干预至关重要.
研究的目的:
- 为了比较有和没有CL±P的儿童之间的牙年龄 (DA).
- 调查生长因子基因和DA变异中的单核酸多态 (SNPs) 之间的关联.
主要方法:
- 一项涉及209名5至14岁儿童的横截面研究 (100名有CL±P,109名没有).
- 使用德米尔吉安方法评估牙年龄;从口腔细胞中提取的DNA用于SNP基因定型 (EGF,EGFR,TGFB1,TGFBR2).
- 统计分析包括学生T测试和安诺瓦与邦费罗尼校正.
主要成果:
- 与对照组 (平均DA = -0.01) 相比,患有CL±P的儿童表现出明显延迟的牙年龄 (平均DA = -0.23).
- TGFB1基因中的SNP rs4803455与没有CL±P的儿童的DA变异显著相关 (p <0.01).
- 在患有CL±P的儿童中,研究的SNP和DA变异之间没有显著的关联.
结论:
- 患有CL±P的儿童表现出牙发育延迟.
- TGFB1基因变体rs4803455在没有CL±P的儿童的牙年龄变化中起作用.

Teeth

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...
