自酸蚀和全酸蚀粘接系统用于Ⅰ类洞复合树脂充填的临床效果评价

Clinical evaluation of self-etching and total-etching adhesive systems used in the filling of Class I composite resin restorations

【目的】本研究为前瞻性的随机自身对照试验,目的是比较一步法自酸蚀粘接剂Adper^(TM)Easy One和两步法全酸蚀粘接剂Adper^(TM)Single Bond 2结合Filtek^(TM)Z350通用型树脂充填后牙I类洞老化8年时的临床粘接效果。【方法】31名患者随机分组接受后牙I类洞充填修复治疗,共计64颗患牙每人至少2颗患牙且为偶数,以进行自身对照。使用一步法自酸蚀粘接剂Adper^(TM)Easy One和两步法全酸蚀粘接剂Adper^(TM)Single Bond 2结合Filtek^(TM)Z350通用型树脂进行充填。分别在基线、6个月、1年、2年、8年时根据轻度改良USPHS标准对试验修复体进行评价,同时对不同粘接剂组内及组间使用χ2检验进行统计学分析。【结果】临床8年复查时有42个修复体参与评价,有1例(2.38%)修复体失败,为Easy One自酸蚀粘接剂组(4.76%)。【结论】自酸蚀粘接剂Adper^(TM)Easy One和全酸蚀粘接剂Adper^(TM)Single Bond 2的临床粘接效果并无显著性差异。

【Objective】To evaluate the 8-year performance of an composite resin(FiltekTMZ350)in Class I restorations placed with a one-step self-etch(AdperTMEasy One)and two-step etch-and-rinse adhesive(AdperTMSingle Bond 2)in vivo in this prospective random self-control trial.【Methods】A total of 31 patients were randomly divided into groups,who were treated with Class I restorations of the same composite resin bonded with either a single step self-etch adhesive or a control 2-step etch-and-rinse adhesive.There were 64 affected teeth,at least two per person and even number of teeth for self-control.The restorations were placed with a one-step self-etch(AdperTMEasy One)and two-step etch-and-rinse adhesive(AdperTMSingle Bond 2).The 64 restorations were evaluated using slightly modified USPHS criteria at baseline,6 months,1 year,2 years and 8 years.In different adhesive groups and between the groups,the chi-square test was used for statistical analysis.【Results】A total of 42 restorations were evaluated in 8-year clinical trial.One failed restoration(2.38%)was observed during the follow up.It was in the one-step self-etch adhesive group(4.76%).【Conclusion】No significant difference is observed in overall clinical effectiveness between the two adhesives.
