摘　　要：目的探讨自酸蚀及全酸蚀粘接系统对复合树脂充填术后敏感的影响。方法需行I、II类洞修复的患牙120颗,抽签法随机分为6组,每组20颗牙;常规预备洞型;各组分别使用自酸蚀粘接剂:FL-BOND、AdperPrompt、ClearfilSEBOND、Xeno、ONE-UPBONDF和全酸蚀粘接剂Primer&BondNT粘接,行复合树脂充填,术后1、7、30、90d复诊,评价术后敏感的发生率及敏感程度。结果术后敏感的发生率各组间无统计学差异;术后1、7d全酸蚀Primer&BondNT组术后敏感程度明显高于其他各自酸蚀组,各自酸蚀组间无明显差异;术后30、90d各组间术后敏感程度均无显著差异。结论全酸蚀粘接剂在术后7d内导致的术后敏感程度明显重于牙本质自酸蚀粘接剂,术后30d全酸蚀粘接剂与自酸蚀粘接剂均较少引起术后敏感。Objective To determine whether self-etching primer（SE） would result in less postoperative sensitivity than a total-etch adhesive（TE）. Methods A total of 120 molars and premolars requiring Class I and II restorations were selected and divided into 6 groups, each group including 20 teeth. SE materials（ FL-BOND, Adper Prompt, Clearfil SE BOND, Xeno, ONE-UP BOND F）and TE （ Prime ＆ Bond NT ）were applied respectively in each group. The restored teeth were reexamined at 1 d, 7 d, 30 d, 90 d after restoration to evaluate the pulp sensitivity degree using VAS and sensitivity rate. Results Analysis of variance revealed no significant differences in postoperative sensitivity rate between the SE and TE materials at any recall time （ P 〉 0.05 ）. The degree of postoperative sensitivity of TE was higher than that of SE in 7 days. However, no significant differences were seen at recall time of 30 days and 90 days among different groups. Conclusion Postoperative sensitivity of TE was much more severe than that of SE in 7 days. Postoperative sensitivity of SE and TE seldom happened after 30 days.
