中文摘要:
      目的 探讨三种牙本质脱敏剂对支托窝牙本质过敏症疗效。方法 气吹法和数字化疼痛评判法(VAS) 检测牙本质敏感患者的敏感程度。选87 名共212 颗牙合支托窝牙本质敏感的天然牙，随机用诺华敏（NovaMin）、极固宁（GreenTM Or）和MS Coat 进行脱敏，观察连续脱敏4 天后即刻、1 个月、2个月和3 个月的脱敏效果。比较各脱敏剂不同时段内脱敏有效率的差异。结果 脱敏结束1、2 个月时，诺华敏脱敏有效率高于极固宁（P<0.05）；3 个月时MS Coat 脱敏有效率高于极固宁（P<0.05）。同一种脱敏剂不同时段比较发现，极固宁在2 个月时脱敏有效率低于脱敏后即刻有效率（P<0.05），诺华敏在3 个月时脱敏有效率低于1 个月时脱敏有效率（P<0.05）。结论 诺华敏和MS Coat 脱敏效果优于极固宁；极固宁和诺华敏用于支托窝脱敏，有必要分别在脱敏2 个月和3 个月后再进行脱敏治疗。
英文摘要:
      Objective To compare the effectiveness of three desensitizers in treating dentine hypersensitivity after occlusal rest preparation. Methods A total of 87 subjects(212teeth) were recruited into the study and stratified into 3 balanced groups. The sensitivity scores were recorded in visual analogue scale(VAS) by the subjects. The teeth in each group were treated with one of three kinds of desensitizers including NovaMin/ GreenTM Or and MS Coat. The desensitising efficacy was evaluated post treatment immediately,or 1,2 and 3 m after treatment. Results At 1 and 2 m after treatment, the desensitising efficacy of NovaMin was better than that of GreenTM Or (P<0.05); At 3 m after treatment, the desensitising efficacy of MS Coat was better than that of GreenTM Or (P<0.05). As for GreenTM Or, the desensitising efficacy 2 m after treatment was lower than that post treatment immediately(P<0.05); As for NovaMin, the desensitising efficacy 3 m after treatment was lower than that 1 m after treatment(P<0.05). Conclusion NovaMin and MS Coat were more effective than GreenTM Or in the treatment of dentine hypersensitivity due to occlusal rest preparation.If NovaMin and GreenTM Or were used to treat the dentine hypersensitivity after occlusal rest preparation, it was necessary to apply them again 2 and 3 m later,respectively.
