摘　　要：目的评价一种新型通用型牙本质粘接剂All Bond Universal对Ⅴ类洞边缘的封闭效果。方法 120颗新拔除的正常双尖牙随机分为4组(30例),分别在颊舌侧颈缘上1 mm处制备标准的Ⅴ类洞(2 mm×2 mm×2 mm),分别用新型通用型粘接剂All Bond Universal(全酸蚀和自酸蚀两种方法)、全酸蚀粘接剂Prime&Bond NT和自酸蚀结剂G Bond进行粘接和样本制备,经50%氨化硝酸银染色后,体式显微镜下观察边缘微渗漏的染色情况,记录评分结果,数据用SPSS 20.0软件包进行统计学分析。结果 3种粘接剂均存在微渗漏现象,使用All Bond Universal的微渗漏评分低于同种使用方法的其他两组(P<0.05),All Bond Universal两种使用方法的微渗漏评分差异无统计学意义(P>0.05),龈方微渗漏评分整体高于方(P<0.05)。结论新型通用型牙本质粘接剂All Bond Universal是一种临床应用方便、有效的牙本质粘接剂,全酸蚀和自酸蚀两种方法对边缘微渗漏的影响无差异,但其远期效果须进一步实验研究。Objective To evaluate the sealing effect of a dentin adhesive in Class V restorations. Methods Standardized mixed Class V cavities （2 mm × 2 mm × 2 mm）were prepared in 120 extracted premolars that were randomly assigned to 4 groups （n=30 for each group）. Three adhesive systems, All Bond Universal （total-etch and self-etch）, Prime ＆ Bond NT, and G bond and resin composite, were applied to each group following manufactures＇ instructions. The teeth were immersed in 50 % ammoniacal silver nitrate and depth of penetration was evaluated under a microscope, and data were statistically analyzed by SPSS 20.0 software. Results Microleakage was observed in all groups. All Bond Universal （total-etch） scores were lower than the other two groups （P 〈 0.05）. There was no difference between total-etch and self-etch when All Bond Universal was used （P 〉 0.05）. Higher microleakage scores were observed along the gingival margin than along the occlusal margin in all groups（P 〈 0.05）. Conclusion New universal adhesive （All Bond Universal） is a convenient and efficient adhesive. Total-etch and self-etch have no influence on marginal microleakage the long-term effect need further study.
