Abstractdc.description.abstractObjectives. To measure microshear bond strength ( SBS) and nanoleakage (NL) of self-etchuniversal adhesives under core buildup restorations using different curing protocols, at 24 hand after 6-month water storage.Methods. Middle dentin of 55 molars was divided into: Clearfil Universal Bond [CFU],Prime&Bond Elect [PBE], and One Coat 7 Universal [OCU]. All-Bond Universal [ABU] andClearfil SE Bond [CSE] were used as control. CFU, PBE and OCU were: light-cured [LC], dual-cured [DC] and self-cured [SC]. Data were analyzed separately (two-way ANOVA), Tukey’stest (˛ = 0.05).Results. SBS: At 24 h OCU/LC resulted in statistically higher SBS than ABU. CSE/DC showedstatistically higher SBS than all DC adhesives. PBE/LC resulted in significant lower SBSthan the respective DC/SC modes (p < 0.001). At 6-month, both CFU and PBE (LC/SC), resultedin a significant decrease in SBS. SBS for OCU/DC decreased significantly (p < 0.001) com-pared to the respective LC/SC modes. NL: At 24 h, ABU showed %NL similar to CBU/LC andOCU/LC (p > 0.05). CSE/DC resulted in significantly higher %NL than OCU/DC but significantlylower than PBE/DC. CFU/LC/SC resulted in significantly lower %NL than CFU/DC. PBE/SCresulted in significant lower %NL than PBE/LC and PBE/DC. OCU/LC and OCU/DC resulted insignificant lower %NL than OCU/SC (p < 0.001). At 6-month ABU, CSE, CFU/LC and CFU/SC,resulted in a significant increase in %NL.Significance. Self-cured activator and different curing protocols influenced SBS and NL ofself-etch universal adhesives, but this influence was material-dependentes_ES
