护牙素治疗牙本质敏感症的临床疗效及扫描电镜观察

目的：探讨护牙素治疗牙本质敏感症的临床疗效,并观察其再矿化能力。方法：60例240颗患牙随机分为氟化物涂膜组,护牙素组,护牙素＋氟化物涂膜组。第0d、7d接受治疗,第1d、7d、30d,视觉模拟评分法（VAS法）评价其临床疗效。制作离体牙标本,扫描电镜观察上述三种方法对牙本质小管的封闭效果。结果：与治疗前基线比较,氟化物涂膜组和护牙素＋氟化物涂膜组,第1d、第7d和第30d各个时间点均有显著改善（P〈0.05）;护牙素组,第1d有显著改善（P〈0.05）,第7d和第30d无显著效果（P〉0.05）。不同时间点,氟化物涂膜组疗效显著优于护牙素组、护牙素＋氟化物涂膜组疗效显著优于护牙素组和氟化物涂膜组（P〈0.05）。SEM显示大量钙化物沉积于护牙素＋氟化物涂膜组牙本质小管内。结论：护牙素单独使用,治疗牙本质敏感症的效果欠佳。但作为一种辅助治疗手段,可以增强氟的治疗效果。

Evaluation of tooth mousse in dentin hypersensitivity treatment-a clinical and scanning electron microscope observation

Objective:To evaluate the clinical effect of Tooth Mousse in dentine hypersensitivity treatment and observe the reminerilization abillity.Method:60 patients with 240 tooth having cervical dentine hypersensitivity were randomly divided into three groups,fluoride varnish group,Tooth Mousse group,Tooth Mousse and fluoride varnish combination group.Treatment was given on day 0 and day 7.Visual analog scale(VAS) was used to evaluate the clinical effects on day 1,day 7 and day 30.Dentin specimens were treated wit...
