牙齿磨损

To explore the effect of high fluoride and low protein on tooth development and clarify the mechanism of excessive tooth wear, and decalcification of incisors were researched by SEM.

为了探索高氟低蛋白对牙齿发育的影响，阐明牙齿过度磨损的机理，应用扫描电镜对第一、二切齿脱钙前的矿化及脱钙后的基质结构作了观察。

An abrasive system for use in high cleaning, controlled abrasivity dentifrice compositions comprises at least one abrasive silica which may be selected from a first silica having a Radioactive Dental Abrasion in the range 30 to 150 and a second silica an RDA in the range 100 to 300, and a crystalline aluminosilicate having an average crystallite size below 0.2 mu m.

一种用于高度清洁、控制磨损的牙膏组合物的磨料体系，包括可选自放射性牙齿磨损在30-150范围内的第一二氧化硅和RDA在100-300范围内的第二二氧化硅中的至少一种磨料二氧化硅，和平均微晶尺寸低于0.2μm的结晶铝硅酸盐。

During their study, the researchers first examined the teeth of modern-day capuchins, howling monkeys, and other monkey species to discern the marks left by fruits, seeds, and other plants.

A lot of tooth wear starts to show up in the late 30s and 40s," Dr. Jones says."

Jones博士说"在30或40多岁后期，许多人就开始出现牙齿磨损。"

The results showed tooth wear decreased with increasing protein in their diet, and the life-span of the animals increased significantly with improving health condition.

结果表明在枯草高氟期随着蛋白水平的提高显著改善了相应时期发育的牙齿质量，减缓牙齿的磨损速度，从整体上提高了动物的健康水平，有效延长了动物的生存时间。

Tooth wear is defined as the loss of the tooth substance which is not caused by dental plague, caries and injuries.

Methods:Thirty mandibles of Macaca mulatta in the Taihang Mountains were classified into 6 groups according to the sequence and worn degree of teeth.

30例太行山猕猴下颌骨标本，按其齿序及牙齿磨损程度的不同分成6组，并对其18项变量进行了测量、统计和分析。

1Tooth wear was a common phenomena.The degree of tooth wear increased with age.2The tooth wear scores in men were higher than those in women.3Tooth wear was related with biting habit and subfunctional movement.

①牙齿磨损在成年人群中相当常见，磨损程度随年龄的增长呈上升趋势；②男性牙齿磨损发生率高于女性；③牙齿磨损与个人的饮食习惯、副功能运动等有一定联系。

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。
