摘要
目的押评价6种新型牙科粘结剂对牙釉质和牙本质的剪切粘接强度。方法押选用新鲜拔除的人上切牙120个熏随机分为12组,每组制备10个试件熏浸泡在37℃水中24h,在LJ-500型拉力试验机上测定剪切强度(10cm/min)。结果:6种牙科粘合剂与牙釉质的剪切粘接强度分别24.6±2.7、17.6±3.5、16.5±3.2、12.8±2.9、10.1±1.8、10.0±2.8MPa鸦与牙本质的粘接强度分别是16.8±3.7、10.1±1.4、10.0±2.1、18.6±3.3、10.5±2.5、8.2±1.7MPa。结论:与牙釉质的粘接强度值ClearfilSEBond最高,OptiBondSold最低;与牙本质的粘结强度值AllBond2最大,OptiBondSold最小。
This paper is toevaluate the shear bond strength(SBS)of six new dental adhesives tohuman enamel and dentin.120extracted human premaxillary teeth are randomly divided into12groups with10teeth in each.After24-hours immersion in water at37℃,all specimens are loaded in a shear mode in a tensile testing machine with a crosshead speed of10mm/min.The SBSof six adhesives toenamel are24.6±2.7,17.6±3.5,16.5±3.2,12.8±2.9,10.1±1.8and10.0±2.8Mpa for Clearfil SE Bond,Prompt L-Pop Single Bond,All Bond2,Prime&Bond and Opti Bond Sold respectively.Their SBStodentin are16.8±3.7,10.1±1.4,10.0±2.1,18.6±3.3,10.5±2.5and8.2±1.7Mpa respectively.Toenamel Clearfil SE Bond shows the highest mean SBSand Opti Bond Sold shows the lowest.Todentin the SBSof All Bond2is the highest and Opti Bond Sold is the lowest.
