概括

口腔形状在口腔移位犬和对照犬的个体之间存在显著差异. 这种上形态的区别,特别是在部地区更突出的中巴,可能会影响狗的喷发模式.

科学领域:

牙科形态学牙科形态学
矯正牙科矯正牙科是一種矯正牙科.
头骨大和面部成像成像

背景情况:

大的形态与狗的移位有关.
了解口腔形状的变化对于诊断和治疗流离失所的狗至关重要.

研究的目的:

为了比较 palatally displaced canines (PDC), labially displaced canines (LDC) 和对照对象 (CG) 的个体的口腔形态.
通过统计形状分析来研究尾形态和犬体位移之间的关系.

主要方法:

对12-43岁的CBCT图像进行了回顾性研究.
样本:29个PDC,20个LDC,20个CG.
统计形状分析 (Procrustes,PCA) 的冠状 palatal 横截面之间的第一个牙.

主要成果:

在PDC和CG (P=0.009) 之间,口腔形状的平均差异显著 (P=0.009).
在PDC-LDC或LDC-CG组之间没有显著的形状差异.
两组之间切口面积 (心脏大小) 没有显著差异.
PDC组在部区域表现出一个更突出的中板区域.

结论:

口腔形状,而不是尺寸,在口腔移位犬和对照犬的个体之间存在显著差异.
牙区域中一个更突出的中巴与 palatally displaced canines相关. 牙区域中一个更突出的中巴与 palatally displaced canines相关.

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...
