She flosses her teeth by pulling out a long piece of floss, slipping it between her teeth and moving it back and forth and up and down.

她剔牙是抽出一条长的洁牙线，用其在齿间滑动，前后上下地移动。

"The loss of earnings for this crop year may be in the region US$10 million, for the producers and coffee dealers, and will cost the CIB some J$30 million to J$50 million, relative to the original crop projections of a typical crop year," said Gentles.

相对于通常一个普通咖啡年度的产量预计来说，本年度咖啡农及咖啡商的收益损失将会在1千万美元左右，咖啡工业委员会也会因此损失3千～5千万牙币（1美元=89牙币左右）。

Methods Forty patients, who suffer from handicapping dentofacial anomaly and need pull out the maxillary first premolar teeth, were divided into test group (20 patients) and control group (20 patients) randomly.

将40例牙列拥挤，需做减数治疗的牙颌畸形患者，随机分为实验组和对照组各2D例。

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。

To discuss the effects of press-fit surgical technique , implant dimensions and implant thread shapes on the primary stability of immediately loaded implant using the 3-dimensional finite element analysis with the models of the immediately laded implants.

目的：本课题拟建立螺纹型牙种植体即刻负载三维有限元模型，利用即刻负载有限元模型研究种植体挤压就位、种植体长度和直径、种植体不同螺纹形态等因素对即刻负载牙种植体初期稳定性的影响，为临床即刻负载提供理论支撑，以期指导临床工作。

Results:When wide-diameter implant or two-implant were used to replace single mandibular molar, the stress of implant-bone interface was much lower than that of standard-diameter implant restoration. Comparison between wide-diameter implant and two-implant replacement showed that the former created lower stress. The difference was more obvious under oblique loads.

结果：与单个标准直径种植体修复相比，采用单个大直径种植体或双种植体修复单个缺失下颌磨牙均可使种植体-骨界面应力值大大降低；而采用单个大直径种植体修复单个缺失磨牙时骨界面应力值相对较小，以斜向加载时更为明显。

Methods Sixty patients with pulpitis or periapical periodontitis were divided into two groups randomly, which were obturated by continuous wave of condensation technique and lateral condensation technique respectively.

选择牙髓病或根尖周病患者60例，按就诊顺序随机分为两组，分别采用连续波充填技术和冷牙胶侧方加压充填技术进行根管充填。

METHODS: In all the 283 teeth, the root canal of 196 teeth were obturated with paste zinc oxide- eugenal; the other 87 teeth were obturated with Vitapex.

选择283 颗乳牙慢性根尖周炎伴窦道的患牙， 196 颗用氧化锌丁香油糊剂充填， 87 颗用Vitapex 充填。

The tissue responses to MTA were compared with that to amalgam. In 16 premolar teeth of dogs (32 roots), the root canals were cleaned, shaped and obturated under ideal condition.

第一部分：MTA倒充填后根尖周组织的愈合反应和非胶原蛋白的表达4只健康杂种犬，双侧下颌第三、第四双尖牙作为实验牙。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。
