牙齿

Dental amalgam is the greatest source of mercury in the general population and brain, blood and urine mercury levels increase correspondingly with the number of amalgams and amalgam surfaces in the mouth.

牙齿汞齐填充物是一般民众最主要的汞的来源，脑、血液、尿液中的汞浓度会随著口中的牙齿汞齐填充物数目增加而增加。

Dental amalgams are considered medical devices, regulated by the FDA.Even the FDA's new warning stops short of admitting that dental amalgams are dangerous for the general population.

美国食品药品管理局规定牙齿汞合金是被考虑的医学材料，甚至美国食品药品管理局的新警告拒绝承认牙齿汞合金对普通人是危险的。

Methods: The physical volume of 24 bicuspids extracted for orthodontic purposes (16 were imaged with the i-CAT and 8 with the CB MercuRay before extraction) was determined using water displacement technique.

选择10例正畸减数病例拔除的双尖牙24颗，采用排水法物理测量其体积(volume of water， Vw)，其中7例（16颗牙齿）在减数前采用i-CAT进行三维扫描，3例（8颗牙齿）使用CB MercuRay。

However, whether the degree of tooth wear has something to do with tooth microstructure, how specific occlusal factors affect the development of tooth wear, and what kind of relationship exists between tooth wear and bruxism or TMD, all these are not clear yet.

作为磨损发生的主体，牙齿的内部结构与磨损程度之间是否存在一定的关系，牙齿所构成的特定的个体咬合因素及其生物学力学特征会对磨损产生何种影响，口颌系统两大功能紊乱性疾病——磨牙症、TMD与磨损之间存在何种关系，均尚不清楚。

So adsorption of the cariogenic bacterium on the dental surface increased,incidence of the caries also possibly increasd.

口腔内带负电荷的致龋菌在牙齿表面的吸附增加，因而牙齿的龋患率可能也会相应增加。

Chewing can stimulate saliva secretion, combined with the gum in the teeth of the friction effect can enhance the role of dental cleaning to reduce the cariogenic factor, contribute to dental caries.

咀嚼可以刺激唾液分泌，再结合口香糖在牙齿上的摩擦作用，可以增强牙齿的清洁作用，减少致龋因子，有助于防龋。

The potential of the dental crown to the middle point of dental root gradually reduced when the pH value of artificial saliva decreased.So adsorption of the cariogenic bacterium on the dental surface increased,incidence of the caries also possibly increasd.

本研究在人工唾液不同pH值时，通过对牙齿表面电位的测定，来观察牙齿表面电位随着人工唾液pH的变化，情况并探讨二者之间的关系，从而揭示酸的致龋机理，为龋病发病机理的研究提供一些实验数据。

Each jaw of Cephaloscyllium ventriosum contains 55 to 60 teeth, each one of which comes with multiple cusps.

每个东太平洋绒毛鲨的下巴里包含55至60颗牙齿，每颗牙齿上都有多个尖刺。

Loss of the normal anatomy of occlusal surface and the hight of cusps could exert significant influence on mandibular stress transferred from the very teeth.

牙齿咬合面正常解剖形态及牙冠高度的丧失对由牙齿向下颌骨传导的生物力有显著影响。

Since teeth problems can lead to serious health conditions, you may want to brush your cat's teeth once a day with a finger tip brush and pet toothpaste.

由於牙齿的问题，可导致严重的健康状况，您可能会想要刷您的猫的牙齿每天一次与指端刷及宠物牙膏。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
