UNASSIGNED: The aim of this study was to assess the effect of @entity6086 on bond strength of two bioactive cements. One-mm thick longitudinal slabs of root dentin were obtained from freshly extracted @entity1 monorradicular teeth (n   =   60). Simulated root perforations (1   mm in diameter) were prepared in radicular dentin. Thereafter, the specimens were randomly divided into two groups (n   =   30), according to the repair material: @entity8642 (n   =   30) and @entity4800 (BD) (n   =   30). Next, the specimens in each group were further randomly divided into 4 equal subgroups (n   =   15) according to the prior use of @entity15383 : @entity8642 / @entity15383 and BD/ @entity15383 groups: perforations were filled with @entity6086 [ @entity15383 ] and after 7 days, it was removed, and @entity8642 and BD groups: @entity6086 dressing were not used. Push-out test was performed at a crosshead speed of 1   mm/min. Bond strength values were compared statistically using Kruskal-Wallis test and Dunn's post-test at a significance level of 5%. The failure analysis was performed using a stereoscopic and classified as adhesive, cohesive and mixed. The push-out bond strength of @entity8642 and BD was not affected by the prior use of @entity15383 (p   >   0.05). BD yielded higher push-out bond strength values compared with those of @entity8642 , regardless of the use of @entity15383 (p   <   0.05). Mixed @entity177 were predominant in all groups. @entity15383 placement for perforations sealing does not alter the bond strength of @entity8642 and BD to the root dentin. BD presented higher bond strength values than @entity8642 . SCANNING 9999:1-5, 2015.    2015 Wiley Periodicals, Inc.
