氟化泡沫治疗龈下刮治后牙齿敏感的疗效观察

目的：比较龈下刮治后使用氟化泡沫对减轻牙齿敏感的临床效果。方法：选择牙周洁治后患者100例,分为试验组（50例）和对照组（50例）,试验组在龈下刮治后1周连续使用2次氟化泡沫脱敏,对照组单纯进行龈下刮治,观察治疗后1、2、3个月两组PD、VAS值及牙髓电活力值的变化情况。结果：龈下刮治后3个月,试验组和对照组PD均显著降低（P〈0.05）,两组间无统计学差异;与对照组相比,试验组的VAS值显著降低（1.96±1.78）及牙髓电活力值显著增高（32.11±11.16）,差异有统计学意义（P〈0.05）。结论：氟化泡沫在龈下刮治后应用可以起到减轻牙本质敏感的效果。

Effect of Fluoridated Foam in the Decrease of Dentine Sensitivity after Sub-scaling and Root Planing

Objective：To evaluate the effect of fluoridated foam in the treatment of dentine sensitivity（DS）after sub-scaling and root planing.Methods：One hundred patients who had finished super-scaling were divided into test group and control group.Test group was administrated 1.23% fluoridated foam after sub-scaling and root planing and control group was sub-scaling and root planing alone.At the baseline and three months after sub-scaling and root planning,probing depth（PD）and visual analogue scale（VAS）and Electric pulp test（EPT）were observed.Results：No complications were observed in both groups at baseline.After sub-scaling and root planing for three months,probing depth of two groups both decreased and there was no difference.But visual analogue scale（1.96± 1.78）and electric pulp test（32.11±11.16） of the test group were significantly improved compared with one week after sub-scaling and root planing.There was significant difference compared with the control group（P〈0.05）.Conclusion：Fluoridated foam plays a role in the decrease of dentine sensitivity after sub-scaling and root planing.
