AIM: To study the correlation between tooth wear and age as well as gender by investigating the state of average tooth wear on incisal and occlusion surfaces in general population.

In the incontinuous cutting, the wave shape of milling can be looked as periodic function. When the milling wave shape with single-tooth was looked as impulse function, by the Fourier Transform, we can find out that it is composed of sine wave with a given frequency and a series of integer multiple frequency. Discussing on the power function is a major tache for studying on the cutting capability of the complex three-dimension groove milling inserts, so to know the facts that affect the single-tooth milling spectral value, and to observe the dynamic milling wave property from the composition of the power spectral, thus we can design and optimize grooves.

在断续切削中，铣削波形可被看作周期函数，将单齿铣削波形看成为脉冲函数，经过傅立叶变换，可以表示为一个按特定的基本频率变动的正弦波形的分量和许多个按基本频率的整数倍而变动的正弦波形的分量叠加而成，讨论所获得的频谱函数，是研究三维复杂槽型铣刀片切削性能的主要环节，以便了解影响单齿铣削波形幅值谱图的各种因素，并从功率谱图的组成情况来考察动态铣削波形的特性，从而进行槽型的设计和优选。

These results suggested that PTH might be involved in regulating tooth development during its morphogenesis and dent inogenesis and tooth germs were good example in such study.

牙胚培养在观察生长因子对牙齿发育的作用研究是有效的，PTH在牙齿发育中具有一定的促进作用。

If the condition is suitable, being entered the mineral quality in the bone by the outside 渗 can act for the organic quality, tooth and skeleton that the skeleton originally possessed before the putrefied disintegration of the tooth and the skeleton and availably then and intactly the conservancy became a fossil.

如果条件合适，由外界渗进骨内的矿物质在牙齿和骨骼腐烂解体之前能有效地替代骨骼原有的有机质，牙齿和骨骼便完好地保存成为化石。

Methods We observed photographs of 30 implant-supported single crowns, used pink esthetic score standard to count scores according to the comparison of the adjacent tooth or the isonym tooth on the opposite side, and investigated the patients satisfaction rate on aesthetic effectiveness.

观察25例患者30颗单个牙种植义齿周围的软组织状况并与邻近牙或对侧同名牙相比较，用PES计分标准进行计分，并对患者满意度进行调查。
