本文选择了 10 8名患者 4 5 6颗前后磨牙 ,因面磨耗牙本质暴露而引起的牙齿敏感症。采用传统碘酚脱敏和涂墨与不涂墨 Nd:YAG激光照射的三种方法进行疗效比较 ,并用扫描电镜观察离体牙牙本质表面结构及形态改变。结果表明 ,一次治愈率涂墨组优于不涂墨组 ,更优于碘酚组 ;涂黑组一次治愈率与不涂墨组三次治愈率结果相近。并对激光治疗牙齿敏感症的机理、照射能量等进行了初步探讨

This article selected a total of 456 premolar and molars in 108 patients who had tooth sensitivity due to facial dentin exposure. Three traditional methods of desensitization of iodine and desensitization with ink and non-ink coated Nd: YAG laser were compared. The surface structure and morphological changes of dentin were observed with scanning electron microscope. The results showed that the primary cure rate of ink-coated group was better than that of non-ink-coated group and better than iodophenol group. The first-time cure rate of black-coated group was similar to that of non-ink-coated group. The mechanism of laser treatment of tooth sensitivity and irradiation energy were also discussed
