概括

不管牙大小的变化,抗美牙之间每日质分泌率的差异是常见的. 这一发现对于理解牙发育和人类牙的变异至关重要.

科学领域:

人类学是人类学.
发育生物学发展生物学
牙科形态学牙科形态学

背景情况:

抗美菌牙对经常表现出度量差异,但潜在的发育原因尚不清楚.
了解牙尺寸的局部变化是理解牙变化的关键.

研究的目的:

调查抗米牙对的度量差异与每日牙内膜分泌率 (DSR) 的局部变化之间的关系.
确定皇冠尺寸的局部变化是否与DSRs的局部变化相关.

主要方法:

3D扫描人类前骨件 (n=32) 以获得尺度测量.
面膜的组织学分析以记录相应区域的DSR.
在反美牙之间比较尺度测量和DSR.

主要成果:

在16个个体中,有13个个体观察到显著的度量差异.
只有10个具有度量差异的数据库也显示了底层的DSR差异.
在16个个体中,有15个个体在至少一个质区域中表现出显著的DSR差异,而不考虑尺度变化.

结论:

在人类中,抗米牙之间的每日质分泌率差异很普遍.
在3D指标分析和底层的DSR差异之间没有发现确的相关性.
DSR变异是牙发育的共同特征,独立于外部牙形态.

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...
