出牙

The calcium hydroxide cement containing BEMA or EMA and HEMA as resin matrix has good properties. The pulp capping test showed that an ex...

以BEMA或EMA和HEMA为树脂基体材料，凝固后具较好的整体性能，在狗牙上盖髓70天后，可见牙髓组织内形成完整的牙本质桥，显示出良好的盖髓效果。

Stress distribution of the natural periodontal membrane, bionic periodontal membrane and the bone interface of the three models are calculated out by SuperSAP93, when the same load exerted to the three models. Results The stress change of the inside and outside surface of the natural periodontal membrane and bionic periodontal membrane is in the same tendency.

应用螺旋CT对上颌中切牙标本进行扫描，分别建立仿生种植牙、天然牙和骨性结合种植体模型，对3个模型施加同样的载荷，应用Super SAP93软件，计算出天然牙周膜和仿生牙周膜以及3种模型骨界面上的应力分布。

As long as you protect the good kid's baby tooth and make the milk sharp tooth shed off and the Heng sharp tooth harbour time of unanimouslyn and then can't influence a tiger tooth.

只要您保护好孩子的乳牙，使乳尖牙脱落和恒尖牙萌出的时间一致就不会影响虎牙。

Results: Relative diagnostic accordance rate of the clinical exploration and four kinds of image processing setup was the highest（P＞0.01）in the first premolars. Relative diagnostic accordance rate of the clinical exploration and the pseudocolor image setup and negative image setup was the highest（P＞0.01）, and that of the clinical exploration and the pseudo3D image setup and positive image setup was the lowest（P＜ 0.01）, showing statistical differences in the second premolars.

结果：①第一前磨牙：4种图像处理格局下邻面龋的检出结果与临床诊断结果的符合率高，差异无统计学意义（P＞0.01）；②第二前磨牙：负片和伪彩图像格局下邻面龋的检出结果与临床诊断结果的符合率高，差异无统计学意义（P＞0.01）；③正片和伪3D图像格局检出结果和临床诊断结果的符合率低（P＜0.01）。

Mesiodistal and buccolingual crown diameters measured on models were statistically analyzed using the SAS software package.

第二磨牙和第三磨牙是萌出最晚的牙齿，其牙冠宽度的预测，国内外报道很少[2 ，3 ] 。

To see if it is a tusk, teeth kids just want to smoke when uncomfortable epiglottic milk and, if so give him points molar things, such as molar biscuits or fruit to give him bite削成Rodlike

看看是不是要长牙了，孩子牙刚要冒出时因不舒服会厌奶，如果是的话给他点磨牙的东西，如磨牙饼干，或把水果削成棒状给他咬

Results showed sTGC-CM, which is similar with the effect of hTGC-CM, was able to induce human DPSCs to make odontoblastic changes as indicated by remarkable morphological changes, increased proliferation ability, higher multipotential and colony forming capability, and expression of some odontogenic markers in gene and protein levels,such as DSP, DSPP, DMP1, BSP, OCN, OPN.

结果表明：人牙髓干细胞经过一定时间的猪牙胚条件培养基诱导后，能在细胞形态上和细胞周期上发生改变，能具有更高的克隆形成能力和多向分化能力，能维持更好的干细胞特性，具有更强的增殖能力，表达更高水平的碱性磷酸酶，免疫组化和RT-PCR提示诱导后的牙髓干细胞能在蛋白水平和基因水平表达出一些牙向分化的标志，如DSP、DSPP、DMP1、BSP、OCN、OPN等。

Place short and long food chips in posterior occlusion of unilateral left side. When the masticated load was 3、5、7 kg, the displacement of abutments was measured by a LB-high sensitive laser transferring detector to calculate displacement, inclination and torsion of the abutment in mesial-distal, labial lingual and vertical and horizontal directions.

分别在左侧后牙区放置长、短食物片的咬合状态下，负载3 kg、5 kg、7 kg咬合力时，用高精度半导体激光位移测量仪测量并计算出同侧基牙在近远中向、颊舌向的水平位移和倾斜、垂直向的位移和水平旋转，统计分析不同牙尖斜度对基牙位移的影响。

The folk belief governing this practice is that when a new tooth grows in, it will possess the dental qualities, not of the original, lost tooth, but of whatever creature finds it, so the creatures of choice would be those world-class champers, the rodents.

这种习俗依据的民间观念认为，新牙长出来时不具有原先脱落的牙齿的特质，哪种动物发现了掉下来的牙，新牙就具有那种动物的牙的特质。
