The first three largest number of missing teeth is as follows: maxillary first molar, maxillary second molar and mandibular first molar. The first three largest number of resident teeth is as follows: mandibular cuspid, mandibular bicuspid and maxillary cuspid. The cases without occusal relationship account for 19.51%; and the cases which need occlusal reconstruction or occlusal elevation account for 19.51% of all the cases, while food impaction exists in 21.84% cases.

结果：本组老年人平均缺失牙齿9.10颗，缺失最多的前3位牙齿是上颌第一磨牙、上颌第二磨牙和下颌第一磨牙；余留最多的前3位牙齿是下颌尖牙、下颌第一双尖牙和上颌尖牙。19.51%的病例颌骨间无咬合接触关系，19.51%的病例修复时需咬合重建或咬合抬高；21.84%的病例修复前存在食物嵌塞。

Results Fibronectin existed in dental pulp and predentin, and also in space between the wall of dentinal tubule and process of odontoblast in mature dentin. They were mostly distributed in odontoblast layer and round blood vessels and nerves.

结果 纤维粘连蛋白免疫反应普遍存在于牙髓、前期牙本质和成熟牙本质的牙本质小管与成牙本质细胞突起，以成牙本质细胞层，牙髓血管与神经周围最为丰富。

Results: Among the 47 cases, 33 cases were teeth pulpless tissue including 14 endodentically treated teeth and 14 cases were vital teeth with periodontitis, cracked tooth and occlusal traumatism.

结果：牙冠纵折多见后牙，以上颌第一磨牙为多见，其中无髓牙33例，牙折裂前有近一半曾作过根管治疗，活髓牙14例，存在不同程度的牙隐裂，牙周炎和咬合创伤。

Wear of the cam requirements apertognathia welding and replacement parts, disability and in disturbthe, avoid regulation disorder after a series of technology failures, at the same time according to the operating instructions for motorised offset press relations table may require adjustments to the data sheet transfer very lucky to have teeth, drum, delivery of dental clishion three parts in informention begnawing paper delivery must be adjusted in line with a sheet transfer very lucky to have teeth, drum, delivery time dental clishion Zhang arterious, Mr.

磨损的不开牙凹轮请求焊补和调换陈的配件，呈现漏洞，不给乱不静，制止调度井然后带来一系列工艺障碍，同时给根据胶印机搁置仿单的机不静干系外洋所请求的数据举行公道调不静，递纸牙、滚筒不小牙、收纸牙垫不一不小局部在咬纸传达时矮矮务必调不静分歧，递纸牙、滚筒不小牙、收纸牙垫弛不开工夫、弛不开巨细务必分歧，移交不确到位，都是在摈斥咬口纸边咬破障碍时调不静历程洋不该出格夺目的几个题目。

It shows in clinic as tooth sensitivity, pulpitis,periodontitis,food impaction ,deformation of basifacial caused of loss of occlusal height, temporomandibular disorder syndrome, etc. The wear property of artificial tooth material will lead a direct effect to restoration result, when it exists in oral environment. It will cause tooth enamel loss too much in a very short period, if the wear property of artificial tooth superior to tooth enamel; but if it is inferior to tooth enamel, serious wear will occur on restoration occlusions, which will lead to loss of bite functions and even decrease of occlusal vertical dimension, disorder of bite functions, etc. Therefore, it is important to artificialtooth material not only it"s biotic compatibility, mechanical function, chemistry property but also it"s wear property.

当口腔中存在修复体时，人工牙材料的磨耗性能也直接影响临床修复的效果，当其磨耗性能强于天然牙釉质门时，将会引起天然牙釉质过度磨耗；当其磨耗性低于天然牙釉质时，又会在较短时期内引起修复体咬合面磨损过度，失去咬合功能，严重者甚至出现咬合垂直距离降低，咬合功能紊乱等症状因此，对于人工牙材料除了考虑生物相容性、机械性能及化学性能外，还应考虑到材料的磨耗性能，而磨耗率的测定一直是评价天然牙及人工牙磨耗性能的优越指标之一。

Now many manufacturers in order to increase its power in its teeth, dental and dental pad that is similar to the surface of the plinthitic "", such as the radiograph ruled in Heidelberg and teeth of clishion, prodenia, Roland sandbiasting teeth pads, gaobao sulbur, clishion, and so on rubber dental materials are quite good, but in use for some time also fails as a result of wear and tear.

此刻许众制造商为了补充叼牙的叼力，都在牙片和牙垫上安插了近似&网纹&的暗地，如海德堡的牙片屈纹与牙垫平纹、曼罗兰的喷砂牙垫、矮不废的含橡胶牙垫等等，其质料都是很是不错的，但在搁置一段工夫后同样也会因磨损而爆发障碍。

Results Fibronectin existed in dental pulp and predentin, and also in space between the wall of dentinal tubule and process of odontoblast in mature dentin. They were mostly distributed in odontoblast layer and round blood vessels and nerves. In the crown pulp, integral optical density, length density and volume density were 0.49±0.33,38.44±20.7 and 24.56±10.8 respectively.

结果 纤维粘连蛋白免疫反应普遍存在于牙髓、前期牙本质和成熟牙本质的牙本质小管与成牙本质细胞突起，以成牙本质细胞层，牙髓血管与神经周围最为丰富。

A study has indicated the expression of Smad2 in human dental pulp cells, but there are no reports about the functions of Smad2/3 in TGF- P modulating dental pulp repair and tooth development.

本研究的目的是观察人牙髓细胞内Smad2和Smad3分子在TGF-β1信号转导中的作用，以及TGF-β1对二者表达水平的调控方式，并检测Smad2和Smad3在牙胚发育的不同时期和正常、龋坏、炎症牙髓组织中的表达及其变化，旨在从细胞内信号转导水平探讨TGF-β调节成牙本质细胞分化和牙本质形成的分子机理，为揭示牙胚发育和牙髓损伤修复过程中基因表达的调控机制提供一定的实验依据。
