目的:评价氟保护剂和多乐氟联合应用治疗龈上洁治术后牙本质敏感症的临床疗效。方法:对龈上洁治术后出现牙本质敏感症的240颗患牙,随机分为4组:A组(空白对照组);B组(氟保护剂组);C组(多乐氟组);D组(氟保护剂+多乐氟联合应用组),分别观察其处理后的临床脱敏效果。结果:经过脱敏药物处理后,牙本质敏感症状均有所改善,B组、C组和D组均明显优于A组(P<0.01),其中D组优于B组和C组(P<0.05),B组和C组两组之间差异无统计学意义(P>0.05)。结论:氟保护剂和多乐氟的联合应用对龈上洁治术后的牙本质敏感具有理想的治疗效果,且操作简单,安全,临床效果确切。
OBJECTIVE: To evaluate the clinical efficacy of combination of fluoroprotective agents and doxylamine in the treatment of dentin hypersensitivity after supragingival neoplasm. Methods: A total of 240 teeth with dentin hypersensitivity after subgingival scaling were randomly divided into 4 groups: group A (blank control group), group B (fluoride protectant group), group C ); Group D (fluorine protector + combination of multi-Le fluoride group) were observed after treatment of clinical desensitization effect. Results: After treatment with desensitization, the symptoms of dentin were improved. The scores of group B, C and D were significantly better than those of group A (P <0.01), and group D was superior to group B and C <0.05). There was no significant difference between group B and group C (P> 0.05). CONCLUSION: The combined application of fluoroprotective agent and daprofloxacin has ideal therapeutic effect on dentine after supragingival scaling, and is simple, safe and accurate.
