目的：观察生物仿生矿化对牙釉质微裂的修复作用。方法：通过极端温度冻裂实验制备牙釉质微裂模型，分别采用模拟体液（simulated body fluid，SBF）、聚丙烯酸（ployacrylic acid，PAA）仿生矿化液中浸泡24 h，再次对牙釉质进行裂纹重现处理，采用环境扫描电镜（ESEM）观察裂纹形貌和计算裂纹宽度。结果：仿生矿化组较SBF组裂纹宽度小，并具有统计学意义。结论：仿生矿化修复牙釉质微裂具有更稳定的修复效果。

Objective:To explore the biominetic mineralization to repair the dental enamel microcrack. Mehtod: Ex-perimental enamel crack was produced by extremely condition of liquid nitrogen frozen. The microcracked teeth were ran-domly divided into two groups as SBF group and biomimetic mineralization group and immersed into mineralising solution re-spectively for 24 hours. Thereafter, the microcracks were reoccurred by liquid nitrogen frozen repeatedly. The width of mi-crocrack was observed under ESEM. Result:The width of microcrack in biomimetic mineralization group was significant smaller than that of SBF group. Conclusion:Biomimetic mineralization might be helpful to recover the enamel microcrack.
