PalodentV3修复磨牙临面缺损的临床疗效观察 　　【摘要】 目的 观察Palodent V3修复磨牙临面缺损的临床疗效。方法 160颗临面缺损磨牙， 随机分成实验组和对照组， 各80颗。实验组Palodent V3成形系统复合树脂充填， 对照组采用传统半环周型复合树脂充填。于修复后6个月和1年复诊。对比两组效果。结果 实验组修复后6个月的成功率为97.4%、修复后1年的成功率为94.3%， 均高于对照组的33.3%、27.9%， 差异均有统计学意义（P 　　【关键词】 Palodent V3；磨牙临面缺损；复合树脂 　　DOI：10.14163/j.cnki.11-5547/r.2017.02.026 　　Observation on clinical effect of Palodent V3 in repair of molar teeth surface defect ZHAO Wei-peng.

Methods A total of 160 surface defect molar teeth were randomly divided into experimental group and control group， with 80 teeth in each group. The experimental group received Palodent V3 figuration system compound resins filling， and the control group received traditional semicircular compound resins filling. They all had subsequent visit in 6 months and 1 year repair. Curative effect was compared in two groups. Results The experimental group had success rate in 6 months repair as 97.4%， and 94.3% in 1 year repair， which were all higher than 33.3% and 27.9% in the control group. Their differences had statistical significance （P 　　1. 3 观察指标及疗效评价标准 修复后6个月和1年复查。复查时依照美国公共卫生署（united states public health service， USPHS）修复体临床评价标准， 采用双盲法进行问、视、探、叩诊检查， 必要时对照患者修复模型进行判断[3]。①色泽匹配：A：修复体色泽与邻牙色泽匹配；B：修复体色泽与邻牙色泽不匹配， 但这种差异在正常范围内；C：修复体色泽与邻牙色泽不匹配， 且这种差异超出正常范围。②边缘着色：A：修复体边缘与材料和牙齿的着色无差别；B：修复体边缘与材料和牙齿的着色有差别， 但着色未向牙髓方向渗透；C：修复体边缘与材料和牙齿的着色有差别， 且着色向牙髓方向渗透。③邻接关系：A：邻接完好；B：邻接不良；C：无邻接。④继发龋：A：有继发龋；C：无继发龋。⑤修复体折裂：A：无折裂；C：有折裂。⑥磨损程度：A：修复体解剖形态正常， 牙合面无凹陷；B：修复体牙合面微凹陷；C：修复体牙合面明显凹陷。⑦边缘完整性：A：探针沿修复体向牙齿滑动时， 探针无阻碍；B：探针沿修复体向牙齿滑动时， 探针被阻碍， 但探针未达釉―牙本质界；C：探针沿修复体向牙齿滑动时， 探针被阻碍， 且探针已达釉―牙本质界。⑧龈指标：A：无临床可见的炎性反应出现；C：有临床可见的炎性反应出现。疗效结果判定标准：各项结果均为A视为成功；有1项结果为B视为缺陷；有1项结果为C视为失败。 　　1. 4 统计学方法 采用SPSS19.0统计学软件进行统计分析。计数资料以率（%）表示， 采用χ2检验。P 　　综上所述， 相对于传统半环周型树脂直接充填， 分段式Palodent V3技术能够获得更紧密的邻接触关系， 临床效果稳定， Palodent V3分段成型系统优于传统
