摘要： 目的 评价应用Beyond冷光美白结合祛氟剂治疗氟斑牙的临床疗效。方法 将2007年8月至2008年10月于中国医科大学口腔医学院综合急诊科就诊的氟斑牙患者60例随机分为治疗组和对照组，每组30例（轻、中、重度各10例）。治疗组采用Beyond冷光美白术结合祛氟剂治疗;对照组采用Beyond冷光美白术治疗，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，两组中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）;而治疗组中度、重度氟斑牙患者的色阶提高值和有效率明显地高于对照组，差异有统计学意义（P < 0.05）。结论 Beyond冷光美白结合祛氟剂治疗中、重度氟斑牙有良好的临床疗效。

Thirty patients from the treatment group were treated with Beyond cold light bleaching and fluoride-removing material. Thirty patients from the control group were treated with Beyond cold light bleaching . The changes of tooth color were evaluated by VITA shade guide matching after treatment. Statistical analysis was carried out. Results Two groups had satisfying lightening efficacy for light dental fluorosis with 100% bleaching efficacy.
