摘　　要：目的评价应用Beyond冷光美白和30%过氧化氢加过硼酸钠漂白技术对无髓变色牙进行牙内漂白的临床疗效。方法无髓变色牙患者113例随机分为3组,分别采用30%过氧化氢加过硼酸钠(A组)、Beyond冷光美白技术(B组)、Beyond冷光美白技术复合常规内漂白(C组)进行牙内漂白,观察其有效率。结果第1次复诊时有效率,A组29.7%,B组48.6%,C组68.4%,C组有效率高于另A、B组(P<0.05)。第6次复诊时有效率,A组54.1%,B组76.3%,C组97.3%,C组有效率高于另A、B组(P<0.05)。牙齿变色后与开始牙内漂白的时间间隔越短,达到满意疗效的治疗次数越少,A、B、C组平均治疗次数分别为16次、12次和7次。结论 Beyond冷光美白技术复合常规牙内漂白对无髓变色牙有显著增白作用,常规Beyond冷光美白次之,30%过氧化氢加过硼酸钠漂白技术牙内漂白效果较差。Objective To evaluate the clinical effects of internal bleaching on discolored and pulpless tooth by Beyond cold light and 30% hydrogen peroxide combined with sodium perborate. Methods A total of 113 discolored and pulpless teeth were chosen and were randomly divided into three groups,which were inside bleached by Beyond cold light and 30% hydrogen peroxide combined with sodium perborate, respectively. The effectiveness rate was evaluated and recorded. The data were statistically analyzed. Results The effectiveness rate after six treatment was 54. 1% in group of 30% hydrogen peroxide combined with sodium perborate,76. 3% in Beyond cold light group and 97.3% in group of Beyond cold light combined with routine inside bleaching. There was significant difference in the bleaching effect among the three groups. Conclusion Beyond cold light combined with routine inside bleaching in the treatment of discolored and pulpless tooth proved to be a better method.
