摘要/Abstract

摘要： 目的： 评估采用低聚合收缩树脂FiltekTM P90修复楔状缺损的临床疗效。方法： 选择52例患者、共180颗楔状缺损患牙，采用自身对照设计，随机选择每例患者的一侧患牙为实验组，采用FiltekTM P90树脂充填；对侧同名牙为对照组，直接采用FiltekTM Z350 XT 树脂充填。对所有楔状缺损修复体于修复后半年、1年进行对比观察。采用改良美国公共卫生署直接临床评价系统（USPHS）比较2组修复体的质量，采用SPSS19.0软件包对数据进行 χ2检验，评价FiltekTM P90树脂充填楔状缺损的临床效果。结果： 治疗后半年复查，实验组成功率为96.55%，对照组为95.40%。治疗后1年复查，实验组成功率为94.05%，对照组为90.48%。半年及1年复查结果显示,在成功率、固位、边缘着色、边缘密合性、表面形态、色泽协调性、继发龋、牙髓反应等方面，实验组与对照组差异无统计学意义（P>0.05）。结论： FiltekTM P90树脂充填楔状缺损能够取得良好的临床效果，值得推广应用。

Abstract: PURPOSE: To evaluate the clinical effect of a new low-shrinkage composite FiltekTM P90 on restoring dental wedge-shaped defects. METHODS: Fifty-two patients with at least two equivalent non-carious cervical lesions on bilateral teeth (180 teeth with wedge-shaped defect) were enrolled in this study. Self-control design was used in this study. The teeth were randomly divided into experimental group which were restored with low-shrinkage composite FiltekTM P90 in one side, and the control group which were filled with FiltekTM Z350 XT composite resin in the other side. The modified USPHS / Ryge criteria were used to evaluate the treatment effects 6 months and 1 year after treatment. SPSS19.0 software package was used for statistical analysis. RESULTS: The 6-months successful rate in FiltekTM P90 group was 96.55% and 95.40% in control group. The 1 year successful rate in FiltekTM P90 group was 94.05% and 90.48% in control group. There were no significant differences in main indexes, including successful rates ,retention, marginal discoloration, marginal adaptation, surface texture, color match, secondary caries and postoperative sensitivity between the 2 groups (P>0.05). CONCLUSIONS: Low-shrinkage composite FiltekTM P90 is a good choice for treating dental wedge-shaped defects.
