摘要
目的评价不同漂白方法对氟斑牙漂白的临床效果。方法轻中度氟斑牙患者30例随机分为3组,每组10例60颗牙。分别采用联合漂白、激光漂白、家庭漂白3种方法进行上前牙区漂白,在漂白前、漂白后即刻、漂白后1个月、漂白后1年记录其L*a*b*值,比较3组漂白效果及颜色回复情况。应用统计学分析软件CS10.34对数据进行t’检验。结果 3组漂白后的L*a*b*值与漂白前比较差异均有统计学意义(均P<0.05);漂白后1个月,联合组与激光组颜色有所回复(P<0.05);漂白后1年,联合组、激光组颜色与漂白后即刻相比有所回复(P<0.05),与漂白后1个月相比颜色回复差异无统计学意义(P>0.05);家庭组颜色回复差异无统计学意义,但1个月到1年期间颜色变化小于治疗后即刻到1个月的变化(P<0.05)。结论 3种漂白方案治疗1个疗程都得到相似的美白效果,但短期内也出现漂白牙的颜色回复,家庭漂白颜色相对稳定,诊室漂白收效快,3种治疗方案各有其适应人群。
ObjectiveTo evaluate the clinical effects of different methods of bleaching on dental fluorosis.Methods Thirty patients with dental fluorosis were divided into 3 groups（Group A,B,C）randomly which were bleached by bleaching,laser bleaching and home bleaching,respectively. Each group contained 60 teeth. The changes of L＊a＊b＊ before bleaching,immediately after bleaching,1 month after bleaching and 1 year after bleaching were used to evaluate the effects of 3 groups.ResultsThe 3 methods showed the significant teeth bleaching effect immediately after bleaching.The teeth colour recovery had statistical difference between 1 month after bleaching and 1 year after bleaching in group A and B.The teeth colour recovery didn＇t have statistical difference between 1 month after bleaching and 1 year after bleaching in group C.ConclusionThe 3 methods have significant teeth bleaching effect,although the teeth colour can recover in short time. Home bleaching can provide a more stable effect.
