摘要:

目的    评价Opalescence PF家庭美白系统漂白牙齿的临床疗效。方法    随机选择2007年8月至2010年12月在暨南大学附属惠州口腔医院治疗的着色牙患者60例(四环素牙组和氟斑牙组各30例),用含15%过氧化脲的Opalescence PF家庭美白套装进行牙齿漂白,用美能达接触式色彩色差计分析并比较治疗前后牙面色度的变化,记录受试者术中牙齿酸痛的发生率,并复查评价疗效稳定性。结果    用含15%过氧化脲的Opalescence PF家庭美白系统漂白后,四环素牙组与氟斑牙组牙面平均L*,a*,b *值与治疗前比较差异均有统计学意义(均P < 0.05),平均色差分别为3.89和4.21;术中2组均有部分患者出现不同程度牙齿酸痛症状,但停药后4 ~ 5 h 均能缓解;治疗后6个月,氟斑牙漂白有效率仍达90%(27/30),四环素牙的漂白有效率为86.7%(26/30),与治疗结束时(93.3%和96.7%)比较,差异均无统计学意义(均P > 0.05)。结论    Opalescence PF家庭美白系统治疗着色牙效果显著并具有一定稳定性。
