摘　　要：目的评价532nm Nd:YAG激光在牙齿漂白技术中的临床应用效果。方法选择因氟斑牙、四环素牙、增龄因素导致的牙色暗黄的着色牙患者256例,采用连续输出的532nm Nd:YAG激光,功率设置为1W,照光时间设置为30秒,对不同类型着色牙进行漂白,并与托盘漂白术相对照,通过VITA比色分别就氟斑牙、四环素牙、增龄性黄牙漂白术前及术后的色度变化、术后3个月疗效、术中及术后牙本质过敏发生情况进行比较。结果对氟斑牙、四环素牙及增龄性黄牙532nm Nd:YAG激光漂白法即刻疗效均优于药物托盘漂白法(P<0.05)。而激光漂白组和托盘漂白组在3个月后复查,两者之间治疗上仍有统计学上的差异(P<0.05)。对术中或术后过敏情况进行比较,激光漂白法显著少于较托盘漂白法(P<0.05)。结论532nm Nd:YAG激光漂白法脱色效果显著,较少发生术中或术后过敏。Objective To evaluate the clinical application effects of 532nm Nd:YAG laser on teeth bleaching.Methods A total of 256 patients who had dental fluorosis,tetracycline teeth,or pigmentation teeth with ages were selected.A 532nm Nd:YAG dental laser with output of 1W,30s continue wave was used for bleaching different kind of teeth comparing with matrix bleaching.VITA colorimetry immediately and after 3 months was used to evaluate the chroma changing before and after bleaching.The condition of dentin hypersensit...
