[摘 要]目的 分析两种不同复合树脂在青少年前牙美容修复中的应用效果。方法 选择2023年2月-10月于本院接受前牙美容修复的青少年患者为研究对象，根据所用修复材料不同分为对照组50例和观察组50例。对照组选择光固化复合树脂，观察组选择纳米复合树脂，比较两组牙髓敏感性、自觉疼痛程度、菌斑指数、牙龈指数、龈沟出血指数、口腔疾病发生率、牙齿美观度。结果 两组治疗前后牙髓敏感率比较，差异无统计学意义(P>0.05)，但观察组治疗后1周及治疗后1、3个月自觉疼痛程度评分低于对照组(P<0.05)；观察组治疗后3个月菌斑指数、牙龈指数、龈沟出血指数低于对照组(P<0.05)；观察组口腔疾病发生率低于对照组(P<0.05)；观察组牙齿美观度各项评分低于对照组(P<0.05)。结论在青少年前牙美容修复中，纳米复合树脂可更好地降低牙髓敏感性、自觉疼痛程度，改善口腔健康状态，减少口腔疾病，提高牙齿美观度。
