可流动复合树脂充填楔状缺损初期临床效果评估

Incipient clinical evaluation of flowable composite in filling wedge-shaped defects

目的:比较可流动复合树脂与复合体充填楔状缺损的初期临床效果。方法:选择37例136颗楔状缺损患牙随机分为4组,分别使用可流动复合树脂(Aeliteflo)、复合体(DractAP)进行充填,2种材料又按照楔缺是否备洞分为两个亚组。于修复后6个月、12个月用改良USPHS系统评价其临床疗效。用Fisher确切概率法对结果进行分析(α=0.05)。结果:随访6个月时,边缘密合性4组间差异有统计学意义(P<0.05);其余各项指标在6个月、12个月评价时4组间差异均无统计学意义,6个月、12个月4组间成功率比较,差异无统计学意义。结论:可流动复合树脂与复合体不论是否备洞充填均能获得较好的临床效果。

Objective： To evaluate the clinical effect of flowable composite versus compomer for restoring cervical wedge-shaped defect in the short period. Methods： 136 teeth with cervical wedge-shaped defects （37 patients） were randomly assigned to four groups, Materials were placed using either flowable composite （Aclite to）, or compomer （Dract AP） with or without preparing cavity. The restorations were clinically evaluated at 6 months and one year after filling with modified USPHS criteria for seven categories. Statistical analysis was completed with Fisher＇ s exact test at a significance level of 5%. Results： No statistically significant difference among four groups was observed for evaluated categories at different time intervals except for marginal adaptation （P〈0.05） at 6 months, the success rate of restoration showed no significant difference among four groups at 6 or 12 months. Conclusion： Both two materials could get satisfied clinical effect for the restoration of non-carious wedge-shaped defect whenever carity was prepared or not.
