小牙

Little girls always display their beautiful cloth to their fellow. Little boys always show their particular toys to their buddy. New-rich knocks out all his teeth, and replace them with gold teeth.

小女孩向同伴炫耀自己漂亮的衣服，小男孩向同伴炫耀自己独有的玩具；暴发户把满嘴白牙磕掉换上金牙，这更是炫耀。

Histochemical study indicated that most of amelogenin stayed in enamel matrix and othersdiffused to dentin, dental tube and odontoblast layer.

组织化学研究结果显示在釉质形成期，釉质蛋白大部分留在釉基质层，也有一部分向牙本质内扩散到牙本质、牙本质小管以及造牙本质细胞层内。

Results Fibronectin existed in dental pulp and predentin, and also in space between the wall of dentinal tubule and process of odontoblast in mature dentin. They were mostly distributed in odontoblast layer and round blood vessels and nerves.

结果 纤维粘连蛋白免疫反应普遍存在于牙髓、前期牙本质和成熟牙本质的牙本质小管与成牙本质细胞突起，以成牙本质细胞层，牙髓血管与神经周围最为丰富。

With the laser power and the time of irradiation increased, the sealing depth of dentinal canaliculi increased.

激光功率不变时，牙本质小管的封闭厚度随照射时间的增加而增加；照射时间相同时，牙本质小管的封闭厚度随激光功率的增加而增加，且具有显著性差异。

Fibronectin usually appeared in dental pulp and predentin, and also in space between the wall of dentinal tubule and process of odontoblast in mature dentin, suggesting that it played an important role in network arrangement of fibronectin which maintained normal form and position of pulp cells and other structures in dental pulp-dentin complex, and also in limitation of diffusion of pulpitis.

纤维粘连蛋白-IR不仅见于牙髓与前期牙本质，而且也见于成熟牙本质的牙本质小管与成牙质细胞突起，它对维持牙髓牙本质复合体各结构的正常位置，形态和防止炎症扩散可能发挥了重要作用。

Results the orifices of dentinal tubule were mostly occluded in Gluma samples and partly occluded in Bisblock samples. Resin layer were observed in Single Bond 2 samples.

结果 Gluma组牙本质小管开口几乎堵塞，Single Bond 2组牙本质表面形成厚的树脂层，BisBlock组牙本质小管开口部分堵塞。

Once was applicable to a small tooth, ex- tooth tooth cleft(the ≤ 2 mms), the whole the tooth light degree arrives to weigh a degree a fluorine spot tooth, whole light degree and mid-degree four wreaths plain toothses, whole tooth heavy degree four wreaths plain tooths match with bleach to also attain better effect, the tooth changes countenance separately, the tooth light degree arranges not and together and needs to change shape separately, and the external injury tooth breaks.

适用於过小牙齿，前牙牙齿间隙（≤2mm ），全口牙齿轻度到重度氟斑牙，全口轻度、中度四环素牙，全口牙齿重度四环素牙配合漂白也可以达到较好的效果，个别牙齿变色，个别牙齿轻度排列不齐，需要改变形状，外伤牙齿折断。

Results Fibronectin existed in dental pulp and predentin, and also in space between the wall of dentinal tubule and process of odontoblast in mature dentin. They were mostly distributed in odontoblast layer and round blood vessels and nerves. In the crown pulp, integral optical density, length density and volume density were 0.49±0.33,38.44±20.7 and 24.56±10.8 respectively.

结果 纤维粘连蛋白免疫反应普遍存在于牙髓、前期牙本质和成熟牙本质的牙本质小管与成牙本质细胞突起，以成牙本质细胞层，牙髓血管与神经周围最为丰富。

Secondly, the incisors grow faster, then the beginning of next to no longer permanent, in the "free" environment will, of course, a large growth, but within the next two years to grow permanent incisors on the natural limits; the most important point is that "parents feel that the incisors are the wrong impression", after the permanent teeth will not grow up stereotypes, so on the child's little face, mouth does not match, it appears to "Super", as the children grow up day by day face, bone development, facial development, such as children and adults will face the size of incisors is coordination of the match,"So we say that time will the children from 'ugly duckling' change 'Swan'."

其次，门牙长得快，这时旁边的恒牙都没开始长，在&无拘无束&的环境下当然会生长得大一点，但两年内旁边恒牙长出就自然限制了门牙；最重要的一点是，&觉得门牙大都是家长的错觉&，恒牙定型后不会再长大，所以放在孩子的小脸、小嘴中不匹配，才显得&超级大&，随着孩子脸形一天天长大，骨头发育、面部发展，等孩子成年时门牙就会和脸形大小十分协调、般配了，&所以我们说时间会让孩子由'丑小鸭'变'天鹅'&。

Compared with the diameter and the density of tubular opening, the mean percentage tubular opening area reflects the feature of the pulp cavity wall more comprehensively.

牙本质小管口的相对面积较单纯的牙本质小管口的直径和密度更能全面地反映不同部位髓腔壁的特征。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
