Ogres with monstrous teeth, and wolves, and bull-headed men; spirits of evil trees and poisonous plants; and other creatures whom I won't describe because if I did the grownups would probably not let you read this book - Cruels and Hags and Incubuses, Wraiths, Horrors, Efreets, Sprites, Orknies, Wooses, and Ettins.

长着怪牙的吃人恶魔、豺狼、牛头怪、恶树精和毒树精；其他动物我就不一一描写了，因为如果我再描写下去，大人可能就不让你们看这本书了——其中有冷面怪、母夜叉、恶梦魔鬼、阴魂、恐怖魔鬼、小妖精、大头鬼和小头鬼等等。

The obvious sealing effect of HA micro-particles on dentinal tubules was observed.

①The shape of the tubular openings has a corelation with both the arrangement of the dentinal tubules and their opening sites on the calcospherites.

①牙本质小管口的形态与牙本质小管的走向及其在钙球上的开口的形态与牙本质小管的走向及其在钙球上的开口部位有相关关系。

The clinical characters of oligodontia concluded from this study are following:(1) There is significant difference that more teeth absent and more existent teeth anomalies in patients of oligodontia/S group than in patients of oligodontia/I group, and the peg-shaped upper lateral incisor is the most frequently affected teeth with shape anomaly.(2) Both of the two groups have no significant differences in number of teeth missing between maxilla and mandible as well as that between left and right side.(3) The distribution of teeth missing is bilateral symmetry in both groups, but the frequency of teeth lost are different: excluding the third molar, in oligodontia/I group, the lower second premolar is the most frequently congenitally missing tooth followed by the upper lateral incisor, while in oligodontia/S group, the most frequently missing teeth are mandibular canine and maxillary lateral incisor. Nevertheless, the first molars are the most stable teeth in both groups.(4) In oligodonita/I group, the mean mesiodistal dimensions of all type of existent teeth are significantly smaller than normal value. It is implied that oligodontia is not an isolated phenomenon, but is related to a complex of other dental changes.

对于口腔多个恒牙先天缺失的临床特点有以下初步结论：(1)综合征型先天缺牙患者较单纯型先天缺牙患者恒牙缺失数目更多，平均分别为23.9个和14.9个，且现存牙齿有更多的形态异常，分别为7／10例（70％）和6／22例（27.3％），其中最常见的是上颌侧切牙畸形；(2)两种类型的多个恒牙先天缺失患者的缺牙数目在上下颌及左右侧之间均无差别；(3)两种类型的多个恒牙先天缺失患者在缺失牙位上均呈对称分布，但在具体牙位上有所差异：不计第三磨牙，单纯型先天缺牙最常缺失的牙位是下颌第二双尖牙、其次为上颌侧切牙；而综合征型先天缺牙最常缺失的牙位是下颌尖牙和上颌侧切牙；无论何种情况，第一磨牙均为牙列中最稳定的牙齿；(4)在单纯型先天缺牙患者中，现存恒牙的牙冠宽度较国人正常值偏小，差异显著，提示牙齿形态与多个牙先天缺失有一定相关性。

Because this don't the even precision incises to, want the characteristics to various porcelain hat, function to have to be clear to control in the meantime, and do a characteristic tooth body prepares, at promise enough porcelain layer under the thickness circumstance assurance Be the smallest quantity to whet in addition to tooth body organization.

这是因为未均匀精确切割所致，同时要对各种瓷冠的特点、性能要有清晰掌握，并做出个性化的牙体预备，在保证足够的瓷层厚度情况下保证最小量的磨除牙体组织。

We didn't know what was wrong with her at night. She seemed OK at day time. March 9th, at dinner time when mommy was holding her, she found her had a small tooth bud on her gum. Then we knew she was not comfortable because she is teething now.

Helical milling cutters have a very small number of teeth but a large helix angle.

Helical铣刀有很小量的牙，但是一个大节面角。

Results:The 3-dimensional finite element models of the minimum distal occlusal structure defect with restoration were created, which included metal crown with exterior anatomic morphology of the mandibular first molar, tooth preparation, filling material and the structure of periodontal membrane.

本研究采用逆向工程技术，通过先进的三维激光扫描技术，三维造型设计技术建立几何模型，将几何数据导入有限元分析软件中，建立了右下颌第一磨牙具有根管和远中面(distal occlusal，DO)最小缺损的全冠修复牙体预备体、充填体、金属冠、牙周膜的三维有限元模型。

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。
