“…Accordingly, AH Plus can be considered the gold standard material for testing endodontic sealers' resistance to dislodgment, because previous studies have pointed out that it presents advantages in comparison with other materials usually used (12,21). On the basis of the present results and previous studies (27,28), MTA Fillapex has the potential to capitalize on the biological and sealing characteristics of MTA and, at the same time, improve its flow rate and manipulation characteristics.…”

“…This suggests that the bond strength between the sealer and the root canal dentin was less affected than for the other materials (10,11). When the resistance to displacement increases, the disruption of the sealer/dentin interface becomes less probable, and failure is more likely to occur within the sealer itself (20,21).…”

“…Similarly, in this study, dentin powder addition did not lead to any significant improvements in bond strength. Taking together the results of the previous study 25) and this study, it seemed that the duration of the neutralizing effect of dentin powders after mixing with adhesive requires further investigation.…”

“…In a previous study, AH Plus and Hybrid Root SEAL were mixed with dentin powders to improve their bonding to root dentin 25) . However, dentin powder incorporation had a negative effect on the shear bond strength of AH Plus, although it did not significantly affect the bond strength of Hybrid Root SEAL compared to the non-powder mixed version.…”

This study evaluated the effect of different amounts of dentin powder (DP) mixed in Clearfil SE Bond (CSB) or Single Bond (SB) on adhesion to dentin. Human third molars (n=96) were sectioned to expose the mid-coronal dentin and divided into eight experimental groups (n=12 per group), namely, Group 1: CSB, Group 2: CSB+1.5 mg DP, Group 3: CSB+3 mg DP, Group 4: CSB+4.5 mg DP, Group 5: SB, Group 6: SB+1.5 mg DP, Group 7: SB+3 mg DP, and Group 8: SB+4.5 mg DP. Filtek Z250 composite was bonded onto dentin, and all specimens were subjected to shear bond strength test at a crosshead speed of 1 mm/min. Highest bond strength was obtained in Groups 1, 2, and 3 (15.1, 13.5, and 16.4 MPa respectively; p>0.05) and the lowest in Groups 6,7, and 8 (5.5, 5.6, 4 MPa; p>0.05). DP addition, regardless of amount, adversely affected the bond strength of SB. Bond strength of CSB was not affected when 1.5 or 3 mg of DP was added.

“…3 AH Plus is an epoxy-based sealer used as a standard in several bond strength studies. [4][5][6] On the other hand, other sealers have also been used in endodontic treatment. Sealapex, with a new composition, is a salicylate-based resinous sealer with low citotoxicity, but with a lower bond strength compared to iRoot and AH Plus sealers.…”

effect of calcium hydroxide dressing on push-out bond strength of endodontic sealers to root canal dentin Abstract: The aim of the present study was to evaluate the effect of calcium hydroxide dressing on the bond strength of three commercially available endodontic sealers (MTA Fillapex, Sealapex, and AH Plus) to root canal dentin. Sixty slices of extracted human canines were obtained from cervical, middle, and apical root thirds. Root canals were standardized and specimens were filled and divided into six groups (n = 10): G1, MTA Fillapex; G2, Sealapex; and G3, AH Plus, with prior application of calcium hydroxide dressing; and G4, G5 and G6, without prior application of intracanal dressing. After 7 days, specimens were submitted to a push-out test. The data obtained were analyzed using the ANOVA and Tukey tests (α = 5%). Fracture modes were classified as adhesive, cohesive or mixed. The results of sealer bond strength to root canal dentin varied according to the sealer, root third and prior dressing application. Overall, calcium hydroxide dressing reduced bond strength in all root thirds, but the reduction was significant only for AH Plus, at the cervical (3.25 ± 1.69) and apical (4.43 ± 1.65) thirds (p < 0.05). AH Plus showed the highest bond strength for all root thirds (p < 0.05) compared to the other groups. G1, G2, G4 and G5 showed similar bond strength values for all root thirds (p > 0.05). In conclusion, the calcium hydroxide dressing only had a negative effect on the bond strength of AH Plus, at the cervical and apical thirds. On the other hand, the bond strength values for MTA Fillapex and Sealapex were lower than those for AH Plus and, whereas the mixed failure mode predominated for AH Plus, the adhesive failure mode predominated for MTA Fillapex and Sealapex.
