牙骨质

Objective: To investigate the effect of pulsed Nd:YAG laser with sodium-fluoride on artificial caries of human dentine and cementum in vitro.

目的 ：探讨脉冲Nd ：YAG激光结合氟化钠对离体人牙牙本质、牙骨质人工龋的影响。

BMSCs could form cementum-like and bone-like tissues on the surfaces of cementum and bone observed by light microscope.

牙骨质片组和骨片组培养上清液中均有OC的表达，但牙骨质组较弱。

All these lines have been proven for their capability of differentiation into odontoblast, dentin, pulp, or cementum in vivo.

这些不同来源的牙齿干细胞，在囓齿动物移植实验中，可以分化为牙本质母细胞，进而形成牙本质，或分化成为牙髓结构，或形成牙骨质。

Cementum cementum is a calcified tissue constitute the root surface.

牙骨质 牙骨质是构成牙根表层的钙化组织。

In addition, root resorption of deciduous teeth is not continuous, but discontinuous, intermittent stage in the absorption, the absorption of root surface can be deposited new cementum, may also be near the new bone.

另外，乳牙的牙根吸收不是持续不断的，而是间断的，在吸收间歇阶段，被吸收牙根的表面又可以沉积新的牙骨质，附近也可产生新的牙槽骨。

Dentin tooth dentin constitute the main material, is located in the inner enamel and cementum, it is better hard enamel.

牙本质』牙本质是构成牙齿主体的物质，位于牙釉质和牙骨质的内层，不如牙釉质坚硬。

If this repair over-active, resulting in too many people can make the alveolar bone and cementum of the joint between the solid, deciduous teeth can no longer continue to absorb.

如果这种修复作用过分活跃，产生过多的牙槽骨人就可能使牙槽骨和牙骨质之间发生固着联合，乳牙牙根就不能再继续吸收。

In practice, this is because just before the out of teeth, root is not fully formed, the pulp cavity and apical foramen are large, thin apical cementum caused.

实际上，这是因为之前出牙，根尚未完全形成，牙髓腔和根尖孔大，薄根尖牙骨质造成的。

The dir ection of calcium ion migration in tooth hard tissue is cementum→dentin→enamel .

牙体硬组织中钙离子的迁移规律为：牙骨质→牙本质→牙釉质。

RESULTS: During tooth root patterning, expression of MSX1 was found not only in dental papilla of the apical area, dental sac and odontoblasts, but also in dental attachment apparatus such as cementoblast, periodontal supporting tissues and alveolar bone.

结果：在牙根发育不同时期内，MSX1mRNA不仅在牙乳头、牙囊组织及成牙本质细胞中有阳性表达，而且在牙附着组织，如成牙骨质细胞、上皮根鞘、牙周组织及根周牙槽骨组织中也有表达。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
