[摘 要]目的 探讨纳米光固化复合树脂充填修复楔状缺损的美学效果。方法 选取2022年7月-2023年7月我院收治的65例上颌前磨牙楔状缺损患者为研究对象，按照随机数字表法分为对照组(32例)和观察组(33例)。对照组使用树脂改性光固化玻璃离子材料充填修复，观察组使用纳米光固化复合树脂材料充填修复，比较两组充填修复成功率、美学效果及牙周健康指标。结果 观察组充填修复成功率为96.97%，高于对照组的78.13%(P<0.05)；观察组充填修复后红色美学评分、白色美学评分均高于对照组(P<0.05)；观察组龈沟出血指数、菌斑指数、探诊深度均优于对照组(P<0.05)。结论 纳米光固化复合树脂充填修复楔状缺损充填修复成功率高，具有较好的美学效果，且远期效果可靠。

    [Abstract]Objective To investigate the aesthetic effect of nano-light-cured composite resin filling in the repair of wedge-shaped defects. Methods A total of 65 patients with wedge-shaped defects of maxillary premolars admitted to our hospital from July 2022 to July 2023 were selected as the research objects and divided into control group (32 patients) and observation group (33 patients) according to the random number table method. The control group was filled Wnyg0rQCks9u2xKr0DPt9A==with resin-modified light-cured glass ionomer material ......
