选择因正畸治疗需要而计划拔除的20颗前磨牙进行金属烤瓷全冠牙体预备，其中每2颗牙均为同颌同名牙；采用随机、双盲、自身对照设计分为2组：对照组在牙预备体上直接用氧化锌丁香酚水门汀粘固暂时冠；观察组在牙预备体上涂布极固宁TM后用氧化锌丁香酚水门汀粘固暂时冠。

The following values was measured: angle of cusp line between the second and third molar, impact state and depth, distance from Rickett's Xi to distal cusp of third mandibular molar along the occlusal plane, anterior border of ramus to the third mandibular molar, distance from projection of distal contact point of maxillary third molar to intersection of pterygoid vertical on occlusal plane.The change between pre-and post-treatment was calculated and analyzed with SPSS10.0 software package.α angle, Xi-LTM, R-LTM, R-LTM were tested with independent-sample t test, impact state and depth was tested with Chi-square test. Influence of age on the values was also evaluated.

测量治疗前后的第二、第三磨牙牙尖连线角度、阻生状态和深度，Rickett's Xi点到下颌第三磨牙远中尖距离、下颌支前缘到第三磨牙远中尖距离、翼上颌裂切线到上颌第三磨牙后缘的距离及上、下磨牙的前移量，计算治疗前后各变量的差值，采用SPSS10.0软件包进行统计学分析，α角、Xi-LTM、R-LTM、R-LTM用t检验，阻生状态和深度用χ^2检验，比较年龄因素对各指标的影响。

Teeth of the total were revisited 2 years later and 2-year success rate were evaluated.Results The ratios of adequate filling, underfilling, and overfilling were 79.97%, 14.62% and 5.41%, receptively. Full canal RCT ratio of molar was 89.44%. Average RCT treatment period was 2.8 weeks. 2-year success rate of RCT was 94.39%.

RESULTS: During tooth root patterning, expression of MSX1 was found not only in dental papilla of the apical area, dental sac and odontoblasts, but also in dental attachment apparatus such as cementoblast, periodontal supporting tissues and alveolar bone.

结果：在牙根发育不同时期内，MSX1mRNA不仅在牙乳头、牙囊组织及成牙本质细胞中有阳性表达，而且在牙附着组织，如成牙骨质细胞、上皮根鞘、牙周组织及根周牙槽骨组织中也有表达。

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.
