目的

评价一步法自酸蚀粘接剂Adper Easy One 一年复诊期内的临床效果。

方法

临床选择有2 颗恒磨牙面洞的患者27 例，按随机数表选择其中一颗牙使用Adper Easy one 自酸蚀粘接剂（自酸蚀组），另一颗牙使用Scotchbond 酸蚀剂及Adper Single Bond 2 粘接剂（全酸蚀组），两颗牙均充填Filtek Z350 树脂。 术后即刻、1 周、半年及1 年复诊评价术后敏感，并按USPHS/Ryge 标准评估充填体情况。

结果

自酸蚀组1 例发生术后敏感，全酸蚀组2 例发生术后敏感，两组差异无统计学意义（P ＞0.05）。 全酸蚀组1 例充填体边缘不完整，自酸蚀组所有病例充填体边缘完整，两组差异无统计学意义（P ＞0.05）。 所有充填体颜色匹配、解剖学形态、表面质地均在1 年复诊期内保持良好，未发生洞缘变色及继发龋。

结论

一步法自酸蚀粘接剂1 年复诊期内术后敏感发生率低，临床效果保持良好。

Objective

This study evaluated the clinical performance of a single-step self-etch adhesive system Adper Easy One over a one-year follow-up period.

Methods

Twenty-seven patients who had two permanent molar occlusal caries received following restorations：（1） single-step self-etching adhesive （Adper Easy one， 3M ESPE） was applied to one tooth following manufacturer's instructions；（2） two-step total-etching adhesive （Scotchbond， 3M ESPE； Adper Single Bond 2， 3M ESPE） was applied to the other tooth as the control. Filtek Z350 （3M ESPE） was used as the restorative composite for all restorations. Postoperative sensitivity was evaluated， and the restorations were assessed according to USPHS/Ryge standard at baseline （instantly）， after one week， half a year and one year of clinical service.

Results

Adper Easy One group had one case of postoperative sensitivity， while two cases in the total-etching adhesive group had postoperative sensitivity at one week visit， and there were no significant differences between the two groups （P ＞0.05）. One restoration in the total-etching adhesive group lost marginal integrity at one-year recall， and all other restorations were clinically acceptable，without significant differences between the two groups （P＞0.05）. The indicators of color match， anatomical form and surface roughness maintained sound in all restorations， without marginal staining and secondary caries.

Conclusions

One year follow up showed low postoperative sensitivity rate and satisfactory clinical performance of the single-step self-etch adhesive system.
