【摘要】：目的:对奥敏清牙齿脱敏剂联合Er:YAG激光治疗青少年牙本质敏感症的疗效进行研究。方法:78例(共163颗患牙)青少年牙本质敏感症患者随机分为奥敏清组(n=54)、激光组(n=55)和联合组(n=54),奥敏清组患者给予单一奥敏清牙齿脱敏剂涂布治疗,激光组患者给予单一的Er:YAG激光照射治疗,联合组患者在Er:YAG激光照射后再涂布奥敏清牙齿脱敏剂治疗,比较治疗前、治疗即刻和治疗后1周、1月、3月、6月VAS值、总有效率。另将20颗新鲜离体牙随机分为4组,分别用生理盐水、奥敏清牙齿脱敏剂、Er:YAG激光及奥敏清联合Er:YAG激光处理,扫描电镜观察各模型样本形态。结果:联合组在治疗即刻及治疗后各时间点的VAS值均显著低于奥敏清组和激光组(P0.05);总有效率均显著高于奥敏清组和激光组(P0.05);奥敏清组和激光组在治疗即刻、治疗后1周、1月、3月时的总有效率差异无统计学意义,但激光组在治疗后6月的总有效率却显著高于奥敏清组(P0.05)。扫描电镜结果显示奥敏清、Er:YAG激光及奥敏清联合Er:YAG激光处理均可封闭牙本质小管,且奥敏清联合Er:YAG激光的封闭效果最佳。结论:奥敏清牙齿脱敏剂联合Er:YAG激光治疗青少年牙本质敏感症具有较好的临床效果。
[Abstract]:Objective: to study the curative effect of Aomin Qing tooth desensitizer combined with Er:YAG laser on juvenile dentin hypersensitivity. Methods Seventy-eight cases (163 teeth) with juvenile dentin hypersensitivity were randomly divided into Aomin Qing group (n = 78), laser group (n = 55) and combination group (n = 54). The patients in the laser group were treated with single Er:YAG laser irradiation, and the patients in the combined group were treated with OMQ tooth desensitizer after Er:YAG laser irradiation. The total effective rate was compared before treatment, immediately after treatment and 1 week, 1 month, 3 months and 6 months after treatment. In addition, 20 fresh isolated teeth were randomly divided into 4 groups, treated with normal saline, er: YAG laser and Er:YAG laser respectively. The morphology of each model was observed by scanning electron microscope. Results: the VAS value of the combined group was significantly lower than that of the Aominqing group and the laser group at all time points, and the total effective rate was significantly higher than that of the Aominqing group and the laser group (P0.05), while the total effective rate of the combined group was significantly higher than that of the Aominqing group and the laser group. There was no significant difference in the total effective rate at 1 week, 1 month and 3 months after treatment, but the total effective rate in the laser group at 6 months after treatment was significantly higher than that in the Aomin Qing group (P 0.05). The results of scanning electron microscope showed that both the er: YAG laser and the Er:YAG laser could seal the dentine tubules, and the sealing effect of the laser was the best. Conclusion: Aomin Qing tooth desensitizer combined with Er:YAG laser has a good clinical effect in the treatment of juvenile dentin hypersensitivity.
