摘要： 目的： 评价Nd:Yap激光联合树脂充填治疗敏感型楔状缺损的临床疗效。方法： 选择2017年1月—2017年6月在上海交通大学医学院附属第九人民医院口腔综合科就诊的敏感型楔状缺损患者70例，共144颗患牙，随机分为2组。直接充填组35例患者，74颗患牙直接使用复合树脂充填。联合组35例患者，70颗患牙采用Nd:Yap激光脱敏后复合树脂充填治疗楔状缺损。采用SPSS 13.0软件包对各组患者在统一临床检查标准下的有效率（术后即刻，术后1、3、6个月复查）进行统计学分析。结果： 直接充填组在术后3个月和术后6个月分别有1颗牙和2颗牙充填体脱落。Nd:Yap激光联合树脂充填组在术后3个月和6个月各有1颗牙充填体脱落。2组患牙疗效差异无统计学意义(P>0.05)。Nd:Yap激光联合树脂充填组在术后即刻和术后1、3、6个月的脱敏有效率分别为95.71%、91.43%、87.14%和81.43%，均显著高于树脂直接充填组的82.43%、78.38%、72.97%和64.86% (P<0.05)。结论： Nd:Yap激光联合复合树脂充填治疗敏感型楔状缺损疗效良好，能明显改善牙敏感症状。

Abstract: PURPOSE: The purpose of this study was to explore the effect of Nd:Yap laser combined with composite resin filling on reducing hypersensitivity of dental wedge-shaped defect. METHODS: Seventy cases, 144 teeth with sensitive wedge-shaped defects were selected. The patients were randomly divided into 2 groups and treated as below: 35 cases, 74 teeth in group A were treated with composite resin directly； 35 cases, 70 teeth in group B were treated with Nd:Yap laser combined with composite resin. After treatment, the effective rates under clinical examination standard (immediately, 1, 3 and 6 months after treatment) in both groups were collected and statistically analysed with SPSS 13.0 software package. RESULTS: In group A, one and 2 teeth fillings fell off 3 months and 6 months after treatment,respectively. In group B, one and 1 tooth fillings fell off 3 months and 6 months after operation. There was no significant difference between the two groups (P>0.05). The effective rates of desensitization were 95.71%，91.43%，87.14% and 81.43% in group B, respectively, which were significantly higher than those in group A (82.43%，78.38%，72.97% and 64.86%)(P<0.05). CONCLUSIONS: Nd:Yap laser combined with composite resin filling can treat sensitive wedge-shaped defect effectively and improve the symptoms of tooth sensitivity significantly .
