牙根

We'll give you an Xtray to find out the condition of the root.

我们要给你拍一张X光片，看看牙根的情况。

METHODS: During permanent tooth root formation of dog MSX1 mRNA was detected by in situ hybridization.

采用原位杂交技术，对犬恒牙牙根不同发育时期MSX1mRNA的表达进行观察。

Objective:To evaluate the physiological roles of bmp3,bmp4 and bmp7 during the formation of permanent tooth roots in dog.

目的：探讨bmp3、bmp4、bmp7在牙根发育过程中的生理作用。

As the permanent tooth germ in the jaw with growth, development and direction to the dental occlusal surface of the mobile, so that the roots of deciduous teeth being absorbed, the gradual loosening of deciduous teeth, and finally resulted in loss.

由于恒牙牙胚在颌骨内的生长、发育及向牙齿咬合面方向的移动，使乳牙根部组织被吸收，乳牙逐渐松动，最后造成脱落。

Methods:The expression of bmp3,bmp4 and bmp7 mRNA at different stages of the development of permanent tooth roots was examined by in situ hybridization in 3 dogs aged 12-18 weeks.

采用原位杂交染色技术，观测犬恒牙牙根发育各阶段标本中bmp3、bmp4、bmp7mRNA的定位表达。

The effect of the perpendicularity loading and the oblique loading indicated that the maximum force was at the 1/3 neck of root.

垂直加载和斜向加载结果表明牙根颈1/3处是应力集中部位。

RESULTS: RANKL immunostaining was strong positive in the root of incisor teeth.

结果：切牙牙根周围核因子κB受体活化剂配体蛋白染色强阳性。

Objective: To evaluate the fracture strengths of treated teeth with prefabricated post with different materials.

目的：对不同材质预成桩修复离体牙根后的抗折性能进行比较。

To reconstruct 3-dimension (3D) model of the human maxillary first premolar for biomechanics analysis.

建立成人上颌第一磨牙根管预备后的三维模型，作为今后生物力学分析的基础。

Objective: To investigate the root canal configuration and the incidence and location of the isthmus in extracted maxillary second premolar with single root.

目的：研究离体单根的上颌第二前磨牙根尖1—6mm处根管形态及根管峡部的发生率和位置的情况。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
