Objective : The aim of the present study was to make a long-term assessment on self-etching adhesive system for composite resin restoration and to test the hypothesis that the absence of protective layers was not responsible for long-term pulp complication in this system. Methods : All 150 patients, who received this type of restorations, were recalled after at least 2 years from the time of restoration. Of 47 patients responded (31%), 107 restorations, 2.2 to 6.5 years old, were examined for tooth sensitivity and pulp vitality. The results were analyzed by Fisher's exact test and multivariate logistic regression analysis. Results : No positive case was found in the assessment of tooth sensitivity, while 4 restorations (3.7%) made in deep cavities with pulp protection (3 with short-term postoperative sensitivity) resulted in pulpectomy due to inflammation. The 95% confidence intervals for odds ratio estimated by the multivariate logistic regression analysis were [1.54 to ∞](p=0.020<0.05) for cavity depth, [0.02 to ∞](p=1>0.05) for provision of protective layer, and [1.50 to ∞](p=0.022<0.05) for short-term postoperative sensitivity. Conclusion : Deep cavity and the existence of short-term postoperative sensitivity originally assessed at 7 days were the two critical predictors for the occurrence of pulp complication for the duration (2.2 to 6.5 years) investigated in the present study. The absence of conventional pulp protection was not responsible for the pulp complication in deep cavities with the self-etching adhesive system

目的：本研究的目的是对自酸蚀粘结剂系统用于复合树脂修复的长期效果进行评价，并验证该系统中缺乏保护层不会导致长期牙髓并发症的假说。方法：对150例接受这类修复体的患者在修复后至少2年内进行回顾。在47名有反应的患者(31%)中，107名年龄从2.2岁到6.5岁的修复体接受了牙齿敏感性和牙髓活力的检查。结果采用Fisher精确检验和多因素Logistic回归分析。结果：无1例牙齿敏感度评定阳性，4例(3.7%)因牙髓保护深洞修复(3例术后短期敏感者)因炎症而行牙髓摘除。多因素Logistic回归分析估计的优势比95%可信区间分别为：空洞深度[1.5 4对∞](p=0.020.0 5)，保护层提供[0.0 2对∞](p=1>0.0 5)，术后短期敏感性[1.5 0对∞](p=0.022和0.0 5)。结论：最初在术后7d评估的深腔和存在短期敏感性是本研究调查期间(2.2~6.5年)牙髓并发症发生的两个关键预测因素。无常规牙髓保护不是自酸蚀粘结剂系统深腔牙髓并发症的原因
