Enamel forms the surface layer of tooth coronal, for translucent white strong organization, it is the hardest organization of calcify of camber of tooth body organization. 牙釉质构成牙冠的表层,为半透明的白色硬组织,是牙体组织中高度钙化的最坚硬的组织。
That's because hydrogen peroxide soaks through the protective outer coating of enamel and into the softer layer of dentin underneath, irritating the nerve-rich dental pulp at the core. 这是因为过氧化氢会渗入釉质的外部保护层并进入牙质下面的较为柔软的一层,刺激神经组织比较多的牙髓。
The enamel layer of a tooth is made up of hydroxyapatite crystals, which form microscopic "rods". 牙齿最外层的牙釉质是由我们肉眼看不到的显微小管所组成的。
Etched bur-cut enamel: there were no smear layer on the surface, with some evidence of prism structure. 酸蚀釉质:表面平坦,无法污层,釉柱结构清晰可见。
Results OD value of outer layer enamel was higher than that of inner layer; 结果牙釉质浅层的光密度均值大于牙釉质深层的光密度均值;
Laser-cut enamel; the surfaces were not flat and devoid of a smear layer, with some evidence of prism structure, like fish scale. 激光切割牙釉质:表面不平,无法污层,釉柱结构清晰可见,呈鱼鳞状。
EMS observing showed that the enamel layer of this newly developed alumina glass-infiltrated ceramic could be lessened befittingly, the fresh surface therefore exposed and the holes on the surface deepened and widened applying the polishing and sandblasting method. 通过电镜观察,CAD/CAM用玻璃渗透氧化铝陶瓷表面通过打磨和喷砂可以使釉质层适量减少,新鲜陶瓷表面暴露,并使表面孔隙增大、加深。
Objective: To study the effects of several remineralization solutions with different composition on the artificial demineralization lesions of bovine enamel and the mechanism of remineralization layer formation. 目的:观察不同成份的再矿化液对人工釉质龋表层下脱矿的再矿化作用及再矿化层的形成机理。
Self bonding enamel wire has a bonding layer outside of the insulation layer, and simple heating allows the bonding of coil on to it. 自粘性复合漆包线的绝缘层外有一层粘结层,只需通过简单的加热就能使线圈粘结在一起。
Objective To evaluate the effect of driving forces similar to those found in dental plaque fluid on the enamel demineralization and ultrastructure of surface layer. 目的观察人工菌斑液不同矿物质饱和度(DSEN,DSFA)对釉质表面下脱矿量的变化及其对表面超微结构的影响。
Histochemical study indicated that most of amelogenin stayed in enamel matrix and others diffused to dentin, dental tube and odontoblast layer. 组织化学研究结果显示在釉质形成期,釉质蛋白大部分留在釉基质层,也有一部分向牙本质内扩散到牙本质、牙本质小管以及造牙本质细胞层内。
Not only Fe and Al could diffuse into enamel layer, but also enamel elements could diffuse into metal layer and there was mutual diffusion between Fe and Al. 不仅铁、铝元素可以向瓷釉层扩散,也存在着瓷釉元素向金属层的扩散,以及金属元素Fe、Al之间的相互扩散。
