(1) The 2% glutaraldehyole pulpotomy has the function of killing bacteria and could cure deep caries and early pulpitis;(2) The curative effects of six months after operation is better than that of three months and of upper jaw is better than that of lower jaw by using 2% glutaraldehyole pulpotomy;(3) The prognosis of 2% glutaraldehyole pulpotomy depends on selecting indication and the patients cooperation in the course of operation;(4) It must be early performed with the root canal therapy that the cases of further developing apicitis, the absorption of root apiex is over 1/3, the pulp necrosis and periapical disease.

(1) 2%戊二醛活髓切断术具有杀菌的功能，对于深龋及早期牙髓炎可以治愈；(2) 2%戊二醛活髓切断术治疗乳磨牙牙髓炎六个月后的疗效明显好于三个月的疗效，上颌组疗效明显好于下颌组；(3) 2%戊二醛活髓切断术的预后取决于适应证的选择及治疗过程中患儿的配合程度；(4)对于进一步发展为根尖炎的病例及根尖吸收超过1/3、牙髓坏死和根尖周有病变者，应及早行根管治疗术。

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。

2The distribution of HIF-1 a and COX-2 was unequal;.(3)These findings indicate that HIF-1a and COX-2 may be two important factors in pulpal lesions and there is a significantly hypoxia condiction in inflamed pulp .(4)The increase of HIF-1 a is a possible mechanism for hypoxia preconditioning .(5)Our results suggested that pulpal fibroblasts as well as macrophages might be involved in the pathogenesis of irreversible pulpitis.

和COX一2的表达均有不同程度的变化，在牙髓炎病程中可能发挥着重要的生理和病理作用，③在牙髓炎进程中和牙髓自身修复过程中存在着缺氧环境和缺氧耐受机制，④牙髓成纤维细胞有可能与单核巨噬细胞一同参与牙髓炎的病理进程，且具有修复和免疫功能。

Fibronectin usually appeared in dental pulp and predentin, and also in space between the wall of dentinal tubule and process of odontoblast in mature dentin, suggesting that it played an important role in network arrangement of fibronectin which maintained normal form and position of pulp cells and other structures in dental pulp-dentin complex, and also in limitation of diffusion of pulpitis.

纤维粘连蛋白-IR不仅见于牙髓与前期牙本质，而且也见于成熟牙本质的牙本质小管与成牙质细胞突起，它对维持牙髓牙本质复合体各结构的正常位置，形态和防止炎症扩散可能发挥了重要作用。

Methods: Model of experimental rat pulpitis was established and ICAM-1 expression of normal dental pulp, pulpitis of immediate group,1 day ,3 days, 5 days, 7 days was analyzed by using immunohistochemical and image analysis technique.

建立大鼠实验性牙髓炎模型，用免疫组化法及图像分析技术检测正常牙髓、牙髓炎即刻组、1天组、3天组、5天组、7天组中ICAM-1的表达情况。

Apoptosis are found in rat normal and inflammatory dental pulp, and it may have a important role in pulpitis.Key words apoptosis;pulpitis;TUNEL method;rat

正常牙髓和炎症牙髓中存在细胞凋亡，细胞凋亡在牙髓炎的转归和预后方面可能有一定的作用。

Objective:To investigate the effects of intercellular adhesion molecule-1(ICAM-1) on pulpitis by observing the change of ICAM-1 in experimental rat pulpitis.

R781.3A1005-2720-（201005-0003-03目的：观察细胞间黏附分子-1（ICAM-1）在鼠实验性牙髓炎中的变化，探讨其在实验性牙髓炎中的作用。
