Abstract:
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.
