目的观察应用氟保护漆对老年人牙本质过敏症的疗效。方法将63例牙合面磨耗有牙本质过敏症状老年人的384颗牙,随机分成两组,实验组用氟保护漆治疗,对照组用75%氟化钠甘油治疗,在治疗后即刻、2周、4周进行临床疗效观察与评价。结果总有效率实验组即刻、2周、4周,分别为98.28%、95.70%、93.98%,对照组分别为70.71%、65.51%、48.28%,二组差异有统计学意义(P<0.01)。结论氟保护漆用于老年人后牙牙合面磨耗牙本质过敏症治疗,效果良好,值得推广。
Objective To observe the effect of fluoride protective paint on dentin hypersensitivity in the elderly. Methods A total of 384 teeth with occlusal dentine hypersensitivity were randomly divided into two groups. The experimental group was treated with fluoroprotective paint. The control group was treated with 75% sodium fluoride glycerol. Immediately after treatment, 2 Week, 4 weeks for clinical observation and evaluation. Results The total effective rate was 98.28%, 95.70% and 93.98% in the experimental group at 2 weeks and 4 weeks respectively. The control group was 70.71%, 65.51% and 48.28% respectively. The difference between the two groups was statistically significant (P <0.01) . Conclusion Fluoride-protective lacquer is an effective treatment for dentin hypersensitivity caused by occlusal occlusion of the posterior teeth of the aged, which is worthy of promotion.
