摘要
目的:评价应用Beyond冷光美白术结合祛氟剂脱色协同治疗氟牙症的临床疗效。方法:将75名氟牙症患者根据牙齿着色的轻、中、重度随机分入观察组、对照1组、对照2组。观察组25名患者150颗患牙,采用Beyond冷光美白术结合祛氟剂治疗;对照1组25名患者148颗患牙,采用Beyond冷光美白术治疗;对照2组25名患者148颗患牙,采用祛氟剂治疗。治疗结束后采用Vita比色板比色,计算各组色阶提高值和有效率,并进行统计学分析。结果:治疗后,3组轻度氟牙症患者的色阶提高值和治疗有效率无显著性差异(P>0.05);而观察组中、重度氟牙症患者的色阶提高值和有效率明显的高于对照1组和对照2组,有统计学意义(P<0.05)。结论:Beyond冷光美白结合祛氟剂治疗氟牙症有良好的临床疗效。
Objective：To evaluate the clinical efficacy of combination of Beyond cold light whitening and fluoride-removing material bleaching system for treatment of dental fluorosis. Methods： Seventy-five patients with light, medium and heavy dental fluorosis were randomly divided into three groups. Twenty-five patients with 150 dental fluorosis from the experiment group were treated with Beyond cold light bleaching combined with fluoride-removing material; Twenty-five patients with 148 dental fluorosis from the control group one were treated with Beyond cold light bleaching. Twenty-five patients with 148 dental fluorosis from the control group two were treated with fluoride- removing material. The changes of teeth color were evaluated by Vita shade guide matching after treatment. Results ： All of the light dental fluorosis in three groups had good lightening efficacy and 100% bleaching efficacy. The Shade value improvement and overall efficacy of observer group were better than the control groups for the medium and heavy fluorosis（P 〈0.05 ）. Conclusion： Beyond cold light whitening combined with fluoride-removing material in bleaching is a good method for dental fluorosis bleaching.
