【目的】探讨流动树脂垫衬联合高强度流动树脂在牙邻（牙合）面洞修复治疗中的疗效。【方法】选取接受牙邻（牙合）面洞修复的患者164例，根据修复方法不同分为观察组与对照组，观察组采用流动树脂垫衬联合高强度流动树脂修复，对照组采用“三明治”技术修复。两组治疗后6个月及1年采用改良的USPHS临床修复体质量评估疗效并比较。【结果】修复6个月及12个月后观察组患者修复体边缘着色及术后牙本质敏感症的发生率均显著低于对照组，其差异均有统计学意义（ P ＜0．05）；但两组修复体完整性和继发龋发生率的比较均无统计学差异（ P ＞0．05）。【结论】流动树脂垫衬联合高强度流动树脂在牙邻（牙合）面洞患者修复中的疗效显著，可降低患者的术后牙本质敏感症反应，恢复患牙的形态和美观。“,”[Objective] To explore the clinical efficacies of high‐intensity flowable composite after lining with flowable composite in restoring classⅡcavity .[Methods]A total of 164 patients with classⅡcavity at our hospital from January 2013 to September 2014 were randomly divided into experiment and control groups .The teeth in experiment group were restored with high‐intensity flowable composite after lining with flowable com‐posite while sandwich technique was employed for control group .The modified United States Public Health Service (USPHS) criteria were used to evaluate the treatment outcomes after 6 months and 1 year .[Results]The success rates of marginal discoloration and postoperative sensitivity were higher in experimental group than those in control group . No significant difference existed between restoration integrity and secondary caries .[Conclusion]ClassⅡcavity may be satisfactorily treated with high‐intensity flowable composite after lining with flowable composite .And postoperative sensitivity is lowered and teeth beauty enhanced .
