The micro-chink between filling materials and the wall of root canal were measured with scanning electron microscope in the other 10 teeth of each group. 每组另10颗牙以扫描电镜测量根管壁与牙胶间微缝隙宽度。
One of the best places is on the wall next to the bathroom mirror ( if parents allow!) where students can see it every time they brush their teeth! 最好的一个地方就是在卫生间镜子旁边的墙上(如果父母允许的话),这样学生每天在刷牙的时候都可以看到!
The boy leant against the wall, his teeth set and his eyes glaring upward. 那个男孩斜靠在墙上,牙关紧闭,愤怒的双眼直射上方。
Results MPR was able to demonstrate the relative bone intensity around the implanted tooth and exactly determine the distance of impacted tooth with the buccolingual bone wall or adjacent teeth. 结果MPR可提供埋伏牙所处部位骨组织的相对密度,精确测量埋伏牙各个解剖位置与颊舌向骨壁或邻牙间的距离;
Laser welding thin wall bit is characterized by high welding strength of bit teeth, no falling out of the teeth and mass production by non water dry drilling. 激光焊接薄壁钻头的显著特点是钻齿焊接强度高,不掉齿,可以用于无水干钻,便于实现大批量规模化生产。
Calculation: Different gingival wall designs were used in posterior teeth adjacent to occlusogingival hole. 计算:存后牙邻(?)洞应用不同的龈壁设计,于(?)
Results: NF-kB positive signals were observed in the osteoclasts up to the permanent tooth germ and in odontoclasts in the medial wall of the pulp cavity of deciduous teeth. 结果:NFkB在幼犬替牙期的恒牙胚上方骨组织中的破骨细胞以及乳牙根面和牙髓腔内的破牙细胞中均有阳性信号表达。
Conclusion: Whether or not reserving of pulp chamber wall had an important influence to resistance of teeth after restoration and selecting methods of proper restoration. 结论:髓室壁牙体组织是否保留对修复后牙体的抗折力及修复方法的选择有重要影响。
