4-6个月的宝宝开始为出牙做准备了，很多宝宝都爱咬嘴唇，最好不要让他们形成习惯，日后不好纠正，应该多啃牙胶。

The continuously growing incisor of the rodent is subdivided into a crown analog half on the labial side, with a cervical loop containing a large core of stellate reticulum, and its progeny gives rise to enamel producing.

啮齿类动物的切牙可以终生生长，它被分为了牙冠发育模式的唇侧和牙根发育模式的舌侧，唇侧的上皮包括一个颈环结构，其内含有星网状层细胞，可以不断的分化为成釉细胞并形成釉质。

The odontoblast is thought to be responsible for dentin formation and mineralization during tooth development and dentin reparation.

成牙本质细胞在牙齿发育和损伤修复过程中负责牙本质的形成和矿化。

In an organ culture system under a three-dimensional microenvironment that provides the conditions needed for odontoblast differentiation, a row of odontoblasts can be induced Kikuchi et al.

牙胚器官培养的三维微环境可诱导形成栅栏状排列的成牙本质细胞。

Pearson product moment correlation coefficients were used to analyze the effect of the age, cranial length and maxillary length on the molar's location in the maxilla.

但是后续的实验研究表明，上颌第一恒磨牙的位置并不是固定不变的，它会随着牙弓内、外因素的变化而发生位置的变化，影响错畸形的形成[1]。

Result:Reparative dentin under the biomembrane in opened area was observed in the tested teeth.

结果：4 个术后不同时期的牙在穿髓孔处均有不同程度的修复性牙本质形成。

He effect of antibiotics in inducing the formation of apices is to prevent infection of root canal, rather than direct induction. And TGF-β1 might act as an inductive factor in the cell differentiation of the above-mentioned cells.

GF-β1参与了尖周组织的修复过程，可能诱导了成牙本质样细胞、成牙骨质样细胞和骨样细胞的分化，在牙根继续形成中起着重要作用。

CaB participated in the human odontogen esis. Besides, the express of CaB in human toot h germ development was time-specific and cell-specific.

CaB参与了人釉质及牙本质的形成过程，并且在人牙胚发育过程中的CaB表达具有时间特异性及细胞特异性。

Recent data suggested that Notch receptors and their membrane-bound ligands Delta and Serrate were involved in both patterning and cell fate determination during odontogenesis.

越来越多的证据表明：Notch途径参与了牙齿发育的各个过程，包括牙齿早期发育细胞的增殖、分化过程，决定细胞的定向分化方向，决定成牙本质细胞与成釉细胞的终末分化命运，并且参与牙齿炎症损伤后修复过程，与第三期牙本质的形成有关。

Some likely reasons for the greater proportion of tuskless Asian elephants compared the African elephants may be due to strong selection in the past by humans killing the tusked male elephants and a gene in Asian elephants which is not as recessive.

与非洲象相比，由于人类过去过分捕杀有长牙的公象。形成非逆向基因淘汰的现象，而造成亚洲雄象无牙的比例较大的原因。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.
