查询词典 teeth

Firstly, we performed pulpotomy for posterior teeth and pulpectomy for anterior teeth. And the experiments were divided into four groups. In the first group, nothing was put in the pulp chamber or canals. In the second group, deciduous dental pulp stem cells of mini-pig with cultured medium were transplanted into the pulp chamber and pulp canals. In the third group, deciduous dental pulp stem cells of mini-pig with lovastatin were transplanted. In the fourth group, deciduous dental pulp stem cells of mini-pig with odontoblast induction medium were transplanted.

在动物实验中，我们将迷你猪乳牙的前牙作拔髓，后牙做断髓处理，各分成四组做实验，第一组不放任何细胞、第二组加入迷你猪乳牙牙髓干细胞和培养液、第三组加入迷你猪乳牙牙髓干细胞和lovastatin，第四组加入迷你猪乳牙牙髓干细胞和odontoblast induction medium，观察三个月后，以探讨其牙齿组织是否会再生。

The database was composed of 18 dental treatments from January 1988 to December 2004. The 18 dental treatments included in this study as following: Amalgam fillings (single-, double-, and triple-surface), composite resin fillings of anterior teeth (single- and double-surface), composite resin fillings of posterior teeth (single-, double-, and triple-surface), glassionomer fillings, endodontic treatment (single-, double-, and triple-root), pulpectomy, full mouth scaling, simple tooth extraction, complicated tooth extraction, simple odontodectomy, complicated odontodectomy.

本研究以牙医十八项医疗项目为对象，资料来自中华民国牙医全联会所提供之健保申报资料档，共包含银粉填充、前牙复合树脂、后牙复合树脂、玻璃离子体填充、恒牙根管治疗、乳牙根管治疗、牙结石清除、简单性拔牙、复杂性拔牙、单纯齿切除术、复杂齿切除术等十八项。

Objective More and more residual roots and crowns are preserved following the enhancement of people's self awareness of teeth and the development of root canal treatment, so the restoration of pulpless teeth defected seriously has been the important task of prosthetic clinicians.

研究目的随着人们对牙齿自我保护意识的增强及根管治疗技术的不断发展，越来越多的残根、残冠得以保存，使得大面积牙体缺损修复成为临床修复工作的一个重要内容。

Methods: We established an experimental model of rat molars pulpitis, used homemade Calcium hydroxide compound as pulp-cap in pulpotomy of rats' teeth, Calvital and blank were det as the control groups. Forty rats' teeth in each group were observed using light microscope 4 and 12 weeks after pulpotomy.

建立大鼠早期牙髓炎的模型，应用自制氢氧化钙复合制剂作为鼠牙牙髓切断术的盖髓剂，以calvital作对照组及无盖髓剂作为空白对照组。

Like all old-fashioned country practitioners, Doctor Reefy pulled teeth, and the woman who waited held a handkerchief to her teeth and groaned.

像所有老式的乡村医生，里费医生也给人拔牙。那个候诊的女人，正用一块手帕捂着嘴呻吟着。他丈夫陪着她。

Methods A set of demineralized bovine teeth specimens we re measured for microhardness to assess the degree of remineralization,and other two sets of bovine teeth specimens were examined with polarizing microscope to assess the anti-demineralization and anti-caries effect.

利用显微硬度计测定氟化牛奶和氟水对早期人工龋的再矿化作用。利用偏光显微镜观察氟化牛奶和氟水的抗酸脱矿作用及抗龋作用。

Methods The resinic artificial teeth were deposited with 50nm or 100nm nanometer amorphous diamond film after pretreated with ultraviolet radiation or polarization.The effect of different methods of pretreatment and thickness of nanometer amorphous diamond films on the wearing resistance of resinic artificial teeth was evaluated.

分别用极化和紫外光照射的方法对人工牙进行预处理后，在其表面分别镀制50nm和100nm的纳米非晶金刚石薄膜，通过对其耐磨性能的测试，评价不同预处理方法和不同厚度薄膜对提高人工牙表面耐磨性能的影响。

Results Resinic artificial teeth deposited with 50nm amorphous diamond film after pretreated with polarization are most close to the natural enamel. Conclusion Nanometer amorphous diamond film improves significantly the wearing resistance of resinic artificial teeth.

结果：纳米非晶金刚石薄膜能显著提高树脂人工牙耐磨性能；两种预处理方法中，极化法实验组的耐磨性能明显优于紫外光照法实验组；极化处理后镀膜50nm的人工牙的耐磨性能最接近于天然牙釉质。

Changes in colour, loss of speckling, or abnormal sensitivity are early signs of gingivitis, in which pockets form between the gum and teeth and become infect ed, with inflammation, bleeding, and, in severe cases, loss of teeth.
