摘　　要：目的观察活髓牙漂白术前应用氟化物是否能降低牙齿敏感性,以及其对过氧化氢(HP)类漂白剂的漂白效果有无不良影响。方法将2012年7月至2014年7月在北京军区北戴河疗养院口腔科就诊40例患者随机分为试验组和对照组,两组均接受35%HP漂白治疗30 min,漂白前两组受试牙分别用2%氟化钠(Na F)和双蒸水处理10 min,对比分析两组间漂白效果和牙齿敏感情况。结果比色前试验组的平均比色值是12.4±0.9,对照组为12.5±0.84;治疗后经比色统计,试验组和对照组有效率分别为99.03%和99.33%,经χ2检验组间差异无统计学意义(均P>0.05)。试验组与对照组的平均色阶提高分别为5.20±1.29和5.32±1.58,经配对t检验,组间差异亦无统计学意义(P>0.05)。40例患者中33例(82.5%)出现不同程度的牙齿敏感,其中对照组17例(85.0%)、试验组16例(80.0%),两组牙齿敏感数目方面差异无统计学意义(P>0.05),但牙齿敏感程度试验组低于对照组,差异有统计学意义(P<0.05)。结论变色牙漂白术前局部应用氟化物并不影响漂白效果和漂白深度,但能有效降低牙齿敏感程度。Objective To observe the influence of fluoride on the tooth bleaching effect and to evaluate whether the use of 2 percent sodium fluoride before bleaching regimen would decrease tooth sensitivity when compared with a placebo.MethodsForty participants were divided into two groups：one that received a placebo and another that was treated with fluoride. All patients used 35 percent carbamide peroxide for 30 minutes. Before using CP,the patients were treated by fluoride or placebo for ten minutes. Then we statistically analyzed the perception of the intensity of tooth sensitivity and the shade changes for both groups,as well as the intensity of tooth sensitivity.ResultsThe use of fluoride gel did not affect the whitening efficacy of the CP. We observed no difference between the groups receiving the placebo and the fluoride treatment in terms of tooth sensitivity experience（P 0.05）;however,patients who received the placebo had a higher intensity of tooth sensitivity than the patients who received the fluoride（P0.05）.ConclusionThe use of 2 percent sodium fluoride before each bleaching regimen does not affect the bleaching efficacy of CP. Also,the use of sodium fluoride gel reduces the intensity of tooth sensitivity.
