摘　　要：目的:观察新型整层充填流动树脂一次固化充填深楔状缺损的2年临床效果。方法:纳入左右成对深楔状缺损(深度>2 mm)前磨牙的患者50名,共85对前磨牙,随机分为试验组和对照组,试验组使用整层充填流动树脂一次充填固化,对照组使用传统树脂分层充填固化,比较2组患牙充填后1周牙齿敏感发生率及充填后2年充填体脱落率及边缘染色/继发龋发生率。结果:2组患牙在充填后1周牙齿敏感发生率、充填后2年充填体脱落率、边缘染色/继发龋发生率差异均无显著性(P>0.05)。结论:使用整层充填流动树脂一次固化充填深楔状缺损可达到与传统树脂分层充填相媲美的临床效果。Objective：To observe the effect of ＂bulk-fill＂ flowable resin in filling deep wedge-shaped defects.Methods：50 patients with totally 85 pairs of premolars with deep wedge-shaped defects（depth 2 mm） were included.Each pair of the defects was randomly divided into the test group and the control group,the defects were treated by ＂bulk-fill＂ flowable resin with single cure technique and conventional flowable resin with incremental layering technique respectively,the tooth sensitive rate 1 week after filling,the filling failure rate,the edge coloring and secondary caries rate 2 years after filling of the 2 groups were compared.Results：There was no significant difference between the 2 groups in the sensitive rate 1 week after filling,the failure rate and the edge coloring and secondary caries rate 2 years after filling（P〉0.05）.Conclusion：The ＂bulk-filled＂ flowable resin using single cure technique can acquire the same clinical effect as conventional flowable resin using incremental layering technique in filling deep wedge-shaped defects.
