有尖牙的

For a moment, the thought of sharp teeth and beady eyes made Otis fly higher. But before long, he was trying to hover among the flowers again.

有那么一会儿，想到了狐狸的尖牙和圆眼，奥蒂斯飞高了一些，但没过多久，他又开始低飞在花丛中了。

The world is full of creepy crawly things but there's more to these critters than fangs and hairy legs.

世界充满爬着走痒痒的事物，但是超过尖牙和多毛的腿有对这些生物的更多。

It floats before you, a bulbous body with a central, unblinking eye, and a large maw filled with daggerlike teeth.

它在你面前飘浮着，球根状的身体上有一只位于中央一眨不眨的眼睛，一张尖牙利齿的血盆大口。

Methods One hundred and twenty teeth （140 canals） scheduled to be endodontically treated were randomly selected, 78 canals with apicitis.

方法临床上随机选择拟做根管治疗的120颗牙共140个根管进行研究，其中无根尖炎和有根尖炎者分别为56、84个根管。

The pair resembled lizards, after a fashion, with long, fanged, crocodile heads and thick batlike wings, and they resembled men in their upright stance and cognizant eyes.

他们很像变形的蜥蜴，鳄鱼般的头颅长着长长的尖牙，背上有厚厚的蝙蝠般的翅膀，又像人一样地双足站立，用眼观察。

MTA was an ideal material for management of pulpless permanent teeth with incomplete root formation.

临床观察MTA治疗根尖发育不全并无髓牙和穿孔延迟修补的效果，对前一类病例用MTA制备根尖屏障，在控制感染后，患者仅需来诊1～2次即可完成治疗，7例中有5例根尖暗影完全消失，2例明显缩小，取得了明显的效果。

They were insect-shelled creatures shaped like lizards, with clacking claws and long fangs.

它们长着昆虫一样的外壳，外形有些类似蜥蜴，不过有噼啪作响的利爪和长长的尖牙。

On the termination date, the cultured explants were all examined by Western blot, HE and transmission electron microscope. Our results showed that after 12-days in culture, the cultivation treated with AS-ODN reduced the synthesis of AMBN and had a deformed dental cusp with thinner enamel matrix. Ultrastructure analyses showed that there was hardly any cisternae of the rough endoplasmic reticulum in the ameloblasts at the tip of the cusp of AS-ODN treatedexplants. However, on average the enamel matrix was thinner compared with that in the control group. Furthermore, the collagen fibers in extracellular matrix were found disorganized. These findings seemed to provide a direct experimental evidence that tended to indicate that the arrested AMBN translation in cultured tooth germs might result in the delay of the tooth development.

经用Western蛋白印迹检测表明，所设计的反义核酸对AMBN InRNA具有良好的封闭效果并成功阻断了牙胚对AMBN的表达；在缺乏AMBN情况下，与对照组相比，实验组牙胚在体外可以继续生长发育至钟状晚期，出现成釉细胞和成牙本质细胞的分化，成釉细胞可以分化成为分泌期型成釉细胞，胞浆中缺少合成蛋白质所必需的粗面内质网和高尔基氏体，缺乏溶酶体，表明对蛋白合成和脚的能力降低；实验组牙胚有牙尖形成和基质分泌，但牙尖形态异常，基质形成减少，牙尖周围基质最厚处为O.6卜m，明显薄于对照组的5.spin，基质中胶原纤维粗细不等，排列稀疏， 3 第四军医大学硕士学位论文未见钙化现象，充分证明了AMBN在牙胚发育中参与釉质基质形成和矿化过程，影响胶原纤维和牙本质基质的合成，促进成釉细胞对蛋白质的合成和釉质基质蛋白降解。

67 of old person latent to split tooth carry on clinical diagnosis, adopt the complex treatment method according to different situations to 63. 4 shallow form latent to split tooth, dental pulp normal having subjective symptoms to be only competent to transfer tooth treat jointly; Have deeper crackle as to 5, the vigor of dental pulp is normal, but there is trouble tooth of dentine irritated symptom, prepares against the hole, is filled with on the crack while adjusting the tooth contract; Pulpitis, 22 58 drops of trouble tooth with the sharp disease, symptom of the root already appear to 36, go ahead of the rest steel wire ring pitch or make, bring ring bonding in order to protect corona, rub except that high sharp abrupt slope, after dispelling the tooth and shutting the wound, the root canal with complete regeneration, observe for 2 weeks, after there is no clinical symptom, preceded and repair completely in time.

对63例老年人67颗隐裂牙进行临床诊断，并根据不同情况采用了综合治疗的方法。4颗浅表的隐裂牙，牙髓正常且无自觉症状仅行调牙合治疗；对于5颗有较深裂纹，牙髓活力正常，但有牙本质过敏症状的患牙，调牙合同时在裂隙处备洞、充填；对36颗已出现牙髓炎、22颗伴有根尖病症状的58颗患牙，先行钢丝环扎或做带环粘结以保护牙冠，磨除高尖陡坡，消除牙合创伤后，再行完善的根管治疗，观察2周，无临床症状后，及时做全冠修复。

objective to evaluate clinical effect of the handling protaper nickel-titanium rotary instruments in preparation of canals of posterior teeth.methods 96teeth with pulpitis or periapical periodontitis were instrumented by handling protaper rotary instruments using step-down technique,and by k files using step-back technique for control.all teeth were obturated with lateral condensation methods.the efficiency of preparation was analyzed with ra-diographs before and after operation.results no transportation,apical blockage and ledge were found in test.the technique could keep canals smooth.there were two ledge,one instrument fracture and nine transportation in control.the operative time was shorter and post treatment pain seldom occurred in handling protaper group.conclusion the handling protaper niti rotary instruments can prepare the canals effectively and safety.after the preparation,the canals could be easily washed,sterilized and filled.it is an efficient instrumentation method for posterior teeth's canals and be used widely.

目的 评价手用protaper预备后牙根管的临床效果。方法选取患有牙髓炎和根尖周炎的后牙96例，随机分成试验组和对照组各48例，试验组用手用protaper多锥度镍钛旋转器械逐步伸入法预备根管，对照组用k锉，逐步后退法预备根管，两组均用侧向加压充填法充填根管，根据治疗前后的x线片，评价后牙根管预备效果。结果试验组无根管偏移、根尖阻塞、台阶，且根管壁平滑流畅，无器械折断等并发症发生。对照组有2例台阶形成，器械折断1例，根管偏移9例。试验组操作时间短且术后疼痛轻微。结论应用手用protaper预备后牙根管快速、安全，成形效果好，易于根管冲洗消毒及填充，可视为临床上预备后牙根管的有效方法。

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。
