摘要
目的将氟斑牙的治疗手段有序结合,探讨氟斑牙最佳临床美白治疗方法。方法选取2013年1月至2014年12月本科室就诊且诊断为氟斑牙患者90例,患者均知情同意并签署知情同意书。按照症状(轻度、中度、重度)将患者随机均分为A、B、C组。A组患者(30例,180颗患牙)采取微打磨—酸处理(35%磷酸酸蚀牙面)—冷光美白(Beyond美白凝胶8 h)治疗;B组(30例,175颗患牙)采取微打磨—冷光美白(Beyond美白凝胶8 h)治疗;C组(30例,180颗患牙)采取酸处理—冷光美白(Beyond美白凝胶8 h)治疗。各组患者治疗前后利用Vita比色板进行比色,计算色阶提高值和有效率。结果 3组轻度氟斑牙患者的色阶提高值和治疗有效率差异无统计学意义(P>0.05);A组中、重度氟斑牙患者色阶提高值和有效率与B组、C组比较差异有统计学意义(P<0.05);结论中重度氟斑牙采取微打磨—酸处理—美白有序结合治疗可以取得满意效果。
Objective To evaluate the clinical efficacy of combination of Beyond cold hght whitening and fluoride removing material bleaching system for treatment of dental fluorosis. Methods Ninety patients with light, medium and heavy dental fluorosis were recruited for the study and randomly divided into three groups. Thirty patients with 180 dental fluorosis from the A group were treated with microbrasion and etch and Beyond cold hght bleaching. Thirty patients with 175 dental fluorosis from the B group were treated with microbrasion and beyond cold light bleaching. Thirty pa- tients with 180 dental fluorosis from the C group were treated with etch and Beyond cold light bleaching. The effects of whitening were evaluated by Vita shade guide matching after treatment. Results Good lightening efficacy and 100% bleaching efficacy was achieved in the hght dental fluorosis subjects from all the three groups. The Shade value improvement and overall efficacy of observer group were better than the control groups for the me- dium and heavy fluorosis （P 〈 0.05 ）. Conclusion For moderate to severe dental fluorosis, combination of orderly methods of ＂micro-polished-etch - Beyond cold light-bleaching＂ is more effective and convenient.
