摘　　要：目的:为了检测不同激励方式的氙灯在齿面进行光敏树脂快速固化和光敏齿面漂白过程中,对牙体温升的影响。 方法:本实验将36颗人类离体牙按着色特征分A、B、C三大组,分别为正常牙、氟斑牙、四环素牙三个实验体系。在无水环境 下,分别用不同激励方式的脉冲氙灯进行照射,并同步检测牙体的温升数值和温升保持时间。结果:结果显示,正常牙体在不 同电流密度的短脉冲氙灯的辐照下未产生损害性温升,而进行需进行色素遮盖和氧化漂白的氟斑牙、四环素牙则需要在保证 电流密度的条件下控制短脉冲激励的占空比,并且应保证治疗区域内的风冷条件。Objective: To comparing the different result used Photosensitive -Colophony, Solidification-Photosensitive and Argon Pulsed Light bleaching in the teeth segment What effect would influence the teeth temperature. Methods: According to teeth shades. We divide 36 grains teeth into A(normal teeth) Groups B(stained teeth) Groups C(tetracycline teeth) Groups. On the evaporation Condition, We employing Xe flash lamp to treatment to the teeth segment, meanwhile use the Temperature-meter to Monitor the teeth Temperature changing and changing Periods. Conclusions: Pass through test. Using vary Electric- current Xe flash lamp acting on the normal no scathe. But for stained teeth or tetracycline teeth. We must ensure control the Electric-current density working ratio in normal condition. Also keep the good - cooling condition with the treatment circumatance.
