摘　　要：目的评价30%H2O2溶液热催化漂白联合NaBO3髓腔封药对无髓变色牙内漂白的临床疗效。方法在髓腔屏障保护下,用30%H2O2溶液热催化漂白联合NaBO3髓腔封药,对110例(110颗患牙)无髓变色牙进行内漂白,按照牙齿变色时间分成3组:A组3～5年(80例),B组5～10年(20例),C组10～20年(10例)。观察美白效果,记录患者满意度及不良反应。结果 110例中,显效78例、占70.9%,有效28例、占25.5%,无效4例、占3.6%,总有效率达96.4%。患者满意度为93.6%,未见不良反应发生。A、B、C组总有效率分别为100.0%、90.0%、80.0%,3组比较差异有统计学意义(χ2=13.46,P<0.01)。结论 30%H2O2溶液热催化漂白联合Na-BO3髓腔封药内漂白是一种安全、有效的牙齿增白美容方法,且牙齿变色时间短漂白效果更好。Objective To evaluate the clinical efficacy of 30% hydrogen peroxide （H2O2） ther- too-catalytic bleaching combined with sodium perborate （NaBO3） pulp chamber seal in pulpless discolored teeth. Methods Under the protection of pulp chamber barrier, 30% H2O2 thermo-cata- lytic bleaching combined with NaBO3 pulp chamber seal was performed in 110 pulpless discolored teeth. According to discoloration time, there teeth were divided into three groups： group A （3-5 years,n=80）,group B （5-10 years,n=20） and group C （10-20 years,n=10）.Whitening effect, patient satisfaction and adverse effects were recored. Results Among the 110 teeth,the treatment was markedly effective in 78 （70.9%） ,effective in 28 （25.5%） and ineffective in 4（3.6%）. The total effective rate was 96.4%. Patient satisfaction was 93.6% and no side effects occurred. The total effective rate was 100.0%,90.0% and 80.0% in group A,group B and group C,respectively. There were significant differences among the three groups （X2= 13.46,P〈0.01）. Conclusion Thermo-catalytie bleaching with 30% H2O2 combined with pulp chamber seal with NaBO3 is a safe and effective method for pulpless discolored teeth.
