Dentine hypersensitiveness treated by Nd ∶ YAG laser combined with enamel cement 钕∶钇铝石榴石激光联合釉质粘结剂治疗牙本质过敏症
Objective: To investigate the effect of microwave on surface morphology of enamel, dentin and cement. 目的:研究微波对釉质、牙本质和牙骨质表面结构形态的影响。
The control technology on fluoride pollution in brick and tile, ceramic, enamel and cement processes are reviewed in the paper, especially for the fluoride pollution control in building material industry of Germany. 综述了迄今国内外砖瓦、陶瓷、搪瓷及水泥生产等建材工业氟污染的控制技术,并重点介绍了德国为控制该类氟污染所采取的措施。
ConclusionNd ∶ YAG laser combined with enamel cement has an obvious effect on DH. 结论Nd∶YAG激光联合釉质粘结剂治疗牙本质过敏症有明显疗效。
Conclusions Dry bonding was good for enamel wall and wet bonding was effective on dentin wall. Hydrophilia bonding cement was recommended in dry bonding of enamel and dentin. 结论以釉质壁为主的窝洞干粘结效果显著,以牙本质壁为主的窝洞湿粘结效果好。
When zinc phosphate cement was used as the base material, the magnitude of maximum Von Mises stress and maximum tensile stress in enamel and composite restorations were comparatively lower than those of glass ionomer cement and the stress distribution were more equable. 从基底材料看,磷酸锌粘固粉作为基底时,牙釉质、修复体的最大VONMISES应力及最大拉应力较玻璃离子粘固粉作为基底时要小,且应力分布更均匀。
