| 目的 观察比较3种脱敏剂对支托窝牙本质敏感治疗的效果。方法 选择201颗支托窝牙本质敏感的天然牙，随机使用氟钾酚醛树脂（FK）、不含氟钾酚醛树脂（FR）和Gluma脱敏剂进行脱敏，每组67颗，使用视觉模拟评分法（visual analog scale,VAS）记录其敏感度，比较连续脱敏5天后即刻、1m、2m和3m的脱敏效果以及有效率的差异。结果 3组患者脱敏治疗后，2m时FK组脱敏有效率高于Gluma组，3m时FK组脱敏有效率高于FR组，其余各组不同时间点组间脱敏有效率及VAS值差异无统计学意义（P>0.05）。FR组3m脱敏有效率低于脱敏后即刻、1m、2m，Gluma组3m脱敏有效率低于脱敏后即刻、1m，其余组间脱敏有效率差异无统计学意义。结论 氟钾酚醛树脂脱敏剂和不含氟钾酚醛树脂脱敏剂用于支托窝脱敏效果优于Gluma；氟钾酚醛树脂脱敏剂持久性更好。 |

| Objective The purpose of this study was to compare the effects of desensitizer containing fluorine potassium phenolic resin (FK), desensitizer without fluorine potassium phenolic resin (FR) and Gluma on the treatment of dentine hypersensitivity after occlusal rest preparation. Methods 201 teeth with dentine hypersensitivity at occlusal rest were treated randomly by FK, FR, Gluma and divided into three groups with 67 cases in each group respectively. The sensitivity scores were recorded by visual analogue scale (VAS) at the time of treatment for 5 consecutive days, and the end of 1st month 2nd month, 3rd month. The desensitization efficiency of three desensitizers within each period was compared and the changes in VAS values were observed. Results At the end of the second month after treatment, the desensitising efficacy of FK was superior to the Gluma,while the VAS in FK Group was lower than that of Gluma. After three months, the tdesensitising efficacy of FK was superior to the FR, while the VAS in FK Group was lower than that in FR group. There are no statistical differences in the desensitizing efficacy and VAS among other groups at different time points (P>0.05). The desensitising efficacy at the end of 3rd month after treatment with FR was lower than that at the time of treatment immediately and the end of1st month and 2rd month, while 3 months treatment of Gluma was superior to post treatment immediately and one month. There was no statistical difference in the desensitizing efficacy between each group at other different time points. Conclusion FK and FR are more effective than Gluma in treating dentine hypersensitivity after oc-clusal rest preparation, and FK had a better persistent effect on desensitization. |
