“…Dual‐cured cement, investigated in Group 3, is a material formulated to be used for both post cementation and the core build‐up procedure. Several studies investigated its adhesion to fiber posts , and to intraradicular and coronal dentin. Good adaptation to the post surface was observed , while relatively weak bond strength could be increased by sandblasting or silane application to the post surface .…”

The adhesion of fiber posts luted with simplified adhesive systems has been a matter of great interest over the past years. The aim of this study was to assess the post retentive potential of experimental self-adhesive resin cement (EXP) when used alone and in combination with a self-etch adhesive. Fiber posts were placed in endodontically treated teeth and divided into four groups (n = 6) according the luting material, as follows: group 1 (EXP alone); group 2 (EXP used with self-etch adhesive); group 3 (marketed dual-cured cement used with self-etch adhesive); and group 4 (marketed self-adhesive cement). The push-out test was used to assess the retentive strength of fiber posts (expressed in MPa), and specimens were analyzed under a stereomicroscope to determine failure mode. The adhesive interface between the cement and root canal dentin for each group was evaluated using scanning electron microscopy. The post retentive potential of group 1 (EXP) (7.48 ± 4.35 MPa) was comparable with that of marketed cements from group 4 (6.79 ± 3.68 MPa) and group 3 (8.77 ± 4.58 MPa). When EXP was used in combination with self-etch adhesive (group 2), significantly higher push-out bond-strength values were measured (15.87 ± 4.68 MPa) compared with the other groups.

“…The ultimate tensile strength of Clearfil Flow FX was significantly higher than that of a flowable composite, Protect Liner F. In addition, the ultimate tensile strength of Clearfil DC Core Automix was significantly higher than that of Panavia F.2.0. Clearfil DC Core Automix is used as a dual-cured resin composite for core buildup 36) . However, this can be also applied for cementation of indirect restorations in the clinic.…”

The purpose of this study was to evaluate the effect of resin coating on the microtensile bond strength (MTBS) of indirect composite cores to pulpal floor dentin. Thirty extracted human molars with root canal fillings were used. After post space preparation, dentin surface was coated with either Clearfil SE Bond (SE) or SE with Clearfil Flow FX (SE+FX) for the resin-coated groups, while dentin was treated with ED Primer II (ED) for the non-coated group. Indirect composite cores were cemented with either Panavia F2.0 (PA) or Clearfil DC Core Automix (DC). After 24-hour storage, MTBSs were measured at a crosshead speed of 1 mm/min. Two-way ANOVA indicated that the MTBSs of resin-coated groups were significantly higher than those of the non-coated groups. In particular, the SE+FX/DC group exhibited the highest MTBS. It was thus concluded that resin coating enhanced the dentin bond strength of indirect composite cores to pulpal floor dentin.
