丙酮基和酒精-水基牙本质粘接系统粘接强度比较及粘接界面观察
|
Abstract:
摘要 目的:比较丙酮基和酒精-水基两种不同溶剂类型的全酸蚀牙本质粘接系统粘接强度和粘接界面的微观形态。方法:选择24颗正畸治疗拔除的健康前磨牙,去除合面釉质层,随机分两组,每组选用一种 “两步法”全酸蚀牙本质粘接系统:以丙酮为溶剂的Prime & Bond NT(PB组)和以酒精和水为溶剂的Single Bond 2(SB2)组,粘接后进行微拉伸力检测。以扫描电镜(SEM)和激光共聚焦扫描电镜(LCSM)观察两种牙本质粘接系统的粘接界面。结果:粘接强度PB组(29.49±4.01) MPa,SB2组微拉伸粘接强度为,SB2组为(30.03±4.33) MPa,无统计学差异。两种牙本质粘接系统均可充分渗入脱矿牙本质表层的胶原纤维网和牙本质小管内,形成混合层和树脂突,SB组混合层薄而均匀,树脂突长。结论:不同溶剂类型的两组牙本质粘接系统微拉伸粘接强度无差异,全酸蚀牙本质粘接系统在湿粘接状态下可以对牙本质形成良好的渗透
