[摘 要]目的 探究半导体激光与Beyond冷光在四环素牙齿美白中的临床疗效。方法 选取2021年11月-2024年1月遂宁市中心医院口腔医学中心收治的78例四环素牙患者为研究对象，采用随机数字表法分为对照组和试验组，各39例。对照组行半导体激光漂白治疗，试验组行Beyond冷光美白治疗，比较两组临床疗效、牙齿美白维持效果满意度、牙周指标、不良反应发生情况。结果 两组治疗后即刻总有效率比较，差异无统计学意义(P>0.05)；两组治疗6个月后总有效率比较，差异无统计学意义(P>0.05)；试验组治疗1、3个月后的牙齿美白维持效果满意度优于对照组(P<0.05)；试验组治疗后PLI、GI、SBI低于对照组(P<0.05)；两组不良反应发生情况比较，差异无统计学意义(P>0.05)。结论Beyond冷光较半导体激光在四环素牙齿美白中的效果更佳，其可提高患者牙齿美白维持效果满意度，且治疗后其牙周水平更优，治疗安全性好，值得临床应用。
