【摘要】 目的　探讨NS牙面涂料对牙本质过敏症的治疗机制。方法　用扫描电镜观察NS涂料应用结果。结果　NS牙面涂料在牙本质表面形成结晶 ,覆盖乃至堵塞牙本质小管。结论　NS牙面涂料通过形成结晶堵塞牙本质小管 ,降低了牙本质小管的通透性 ,起到治疗牙本质过敏症的作用更多还原

【Abstract】 Objective To know the mechanisms of treating dentine hypersensitivity by NS Paint. Methods Scanning electron microscopy was used to observe NS paint. Results NS paint grew crystal in the dentine surface, occluding dentine tube. Conclusion NS paint could treat dentine hypersensitivity by growing crystal to occlude dentine tube.更多还原
