目的比较威10(Wy10)牙齿美白技术与冷光美白技术漂白变色牙的的临床效果.方法将100例变色牙(增龄性黄牙78例,中度四环素牙22例)患者随机分为治疗组和对照组,每组50例.治疗组采用Wy10牙齿美白技术治疗；对照组采用BeyondⅡ冷光美白技术治疗,治疗结束后采用Vita比色板比色,计算各组色阶提高值、有效率及牙齿敏感率,并进行统计学分析.结果治疗后,两组变色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),但治疗组和对照组患者治疗后24 h内的敏感率差异有统计学意义(P＜0.05).结论 Wy10牙齿美白技术与冷光美白技术漂白变色牙均可获得满意的美白效果,Wy10牙齿美白技术可显著解决患者因治疗后牙齿敏感而产生恐惧感的状况.
