| 目的 通过对奥敏清和格鲁玛两种脱敏剂临床疗效的比较研究，为医生临床治疗方案提供循证医学证据。方法 按照临床试验纳入标准和排除标准，选择需要做基牙是活髓牙冠桥修复治疗的患者60人，活髓基牙共100颗，按电脑随机数随机分为A、B两组。受试者牙体预备带临时冠，1周后复诊，去除临时冠，用机械刺激法寻找敏感区，进行冷空气喷吹检查，记录治疗前VAS值。A组用奥敏清牙齿脱敏剂脱敏，使用棉签蘸取奥敏清反复涂擦牙齿表面2min，敏感区加强，清水漱口；B组用格鲁玛脱敏剂脱敏，隔湿干燥，使用棉签蘸取格鲁玛反复涂擦牙齿表面，敏感区加强，保持时间为1min，然后轻吹去除液体薄膜。以上两组均重复操作1次。治疗后A组和B组再次进行冷空气喷吹检查，记录治疗后VAS值。结果 A组和B组牙体预备后敏感VAS值水平相近，差异无显著性 (P＞0.05)。A组和B组脱敏治疗后即刻VAS值无显著差异(P＞0.05), A组脱敏术前、术后即刻VAS值有显著差异(P＜0.05)，B组脱敏术前、术后即刻VAS值有显著差异(P＜0.05)。结论 奥敏清和格鲁玛脱敏剂在活髓牙牙体预备后治疗敏感症都能达到很好的脱敏效果，奥敏清使用更加简单方便，具有综合广泛的治疗作用。 |

| To provide evidence-based medical evidence for the clinical treatment of doctors through the comparative study of the clinical effects of two desensitizers. Methods According to the inclusion criteria and exclusion criteria of clinical trials, 60 patients who needed abutment teeth to be treated with crown bridge of living pulp teeth were selected, with a total of 100 living pulp teeth. They were randomly divided into two groups, A and B. Subjects were prepared with temporary crowns, and the temporary crowns were removed at the further consultation 1 week later. Sensitive areas were searched with mechanical stimulation, and VAS before treatment was recorded. Group A used Ominqing desensitizer to desensitize teeth, and used cotton swabs to dip Ominqing on the surface of teeth repeatedly for 2min to strengthen sensitive areas and rinse with water. In group B, Gerumar desensitizer was used to desensitize the teeth and keep them dry. Gerumar was dipped in cotton swabs and repeatedly rubbed on the surface of the teeth. The sensitive areas were strengthened and kept for 1min. Then gently blow to remove the liquid film.The above two groups were repeated once.After treatment, the VAS values of group A and group B were recorded. Results After tooth preparation, sensitive VAS values in group A and group B were similar, with no significant difference(P＞0.05). There was no significant difference in VAS immediately after desensitization between group A and group B(P＞0.05). VAS values before and immediately after desensitization in group A were significantly different (P < 0.05), while VAS values before and immediately after desensitization in group B were significantly different (P < 0.05).Conclusion Both Ominqing and Grumar desensitizers can achieve good desensitization effect in the treatment of sensitive diseases after the preparation of living pulp teeth. Ominqing is more simple and convenient to use and has comprehensive and extensive therapeutic effects. |
