含氟草酸钾凝胶对牙齿敏感症的疗效观察

Effects of potassium oxalate with fluoride gel on dentin hypersensitivity

作者通过临床和扫描电镜观察含氟草酸钾凝胶的抗牙本质敏感作用并研究其作用机制。结果表明，将含氟草酸钾凝胶置于牙托内给病人使用４分钟后，患牙对温度刺激敏感性立即降低，具有显著性意义，扫描电镜观察显示，含氟草酸钾凝胶处理后，牙表面有微球状颗粒沉积，此种颗粒沉积于牙本质小管内具有抗牙齿敏感症作用，文章认为含氟草酸钾凝胶为一种有效、安全的牙齿敏感症治疗药物。

This study observed the potassium oxalate including fluoride gel on the reduction of dentin hypersensitivity both in clinic and in laboratory.The results of the clinical treatment showed that this gel was statistically significant in reducing dentin hypersensitivity when the teeth treating by the gel for 4 minutes.The results of the scanning electric microscope(SEM)research indicated that the gel could create micro-globed particles deposition on the dentin surface.These particles have the ability to block the dentinal tubules and to decrease dentin hypersensitivity. In conclusion,this gel is an effective and safe topical agent for dentin hypersensitlvity treatment.
