“…This finding is in agreement with previous studies 14,23) that showed the MTA-dentin bond failures were usually adhesive. The adhesive mode of failure may be related to the short storage time of the tested materials before the evaluation of bond strength, which was 4 days in the present study.…”

“…Endodontic materials should be resistant to dislocating forces such as functional pressure or condensation. Different methods are used to evaluate the adhesion of dental materials to dentin including the push-out strength, tensile bond strength, and shear bond strength tests 14) . To date, no study has evaluated the effect of placement technique on the bond strength of MTA and Biodentine.…”

The purpose of this study was to evaluate the effects of ultrasonic and manual placement techniques on the push-out bond strength of Biodentine and MTA with and without calcium chloride. One hundred and twenty mid-root slices from forty freshly extracted single-rooted human mandibular premolar teeth were instrumented and randomly divided into six groups (n=20) according to the filling material and placement technique applied, as follows: G1: MTA-manual compaction, G2: Biodentine-manual compaction, G3: MTA+5% CaCl2-manual compaction, G4: MTA-ultrasonic activation, G5: Biodentine-ultrasonic activation, G6: MTA+5% CaCl2-ultrasonic activation. The push-out bond strengths were measured using an Instron testing machine. Data were analyzed using twoway analysis of variance (ANOVA) with Bonferroni correction. The ultrasonic activation significantly enhanced the bond strength values of the materials. Biodentine presented higher bond strength values than that of MTA groups. The addition of CaCl2 to MTA did not improve the bond strength of the material.

Aim: This study aimed to evaluate the push-out bond strength of NeoMTA Plus (NMTA), EndoSequence root repair material fast set putty (ERRMF), biodentine (BD), and ProRoot white mineral trioxide aggregate (PMTA) when used as perforation repair materials after exposure to 2.5% sodium hypochlorite (NaOCl) during the early setting phase. Materials and methods:Horizontal midroot sections were prepared from single-rooted human teeth. Sections (n = 144) were randomly divided into four groups: PMTA, BD, NMTA, and ERRMF. Materials were condensed and allowed to set for 10 minutes. The groups were further divided into two subgroups. The NaOCl group included specimens that were immersed in 2.5% NaOCl for 30 minutes, and the control group included specimens on which a wet cotton pellet was placed over the test material. After 48 hours, the highest force applied to the materials at the time of dislodgement was recorded. Slices were then examined under a digital microscope to evaluate the nature of the bond failure. The surfaces of two specimens from each subgroup were observed by scanning electron microscopy. Data were statistically analyzed with two-way and one-way analysis of variances, independent t-tests, and chi-square tests. The statistical significance was set at 0.05. Results:In NaOCl-treated groups, PMTA showed a significantly higher push-out bond strength than the other three materials (p = 0.00). In the control groups, the bond strength of BD was significantly higher than that of PMTA, ERRMF, and NMTA (p < 0.05). Compared with the control group, NaOCl treatment significantly increased the push-out bond strength of PMTA (p = 0.00) and ERRMF (p = 0.00) and significantly reduced the In ERRMF, the crystals were few in number. Sodium hypochlorite enhanced the crystallization of NMTA. Conclusion:The push-out bond strengths of PMTA and ERRMF were significantly increased after exposure to 2.5% NaOCl in the early setting phase, and those of BD and NMTA were significantly decreased. Clinical Significance:The results of the present study suggest that early exposure of NaOCl increase the push-out bond strength of PMTA and ERRMF. PMTA had the highest push-out values. Therefore, it would be a potentially useful perforation repair material for single visit endodontic treatment.

“…Therefore, it is important to use a push-out assay to evaluate the dentin bond strength of reparative materials. Although several studies have assessed the bond strength of MTA and other materials to dentin (2,3,18), none of them have compared the dislocation resistance of new MTA products (Supra MTA and RetroMTA) and Biodentine. Hence, the aim of the present study was to evaluate the effect of blood contamination on the dislocation resistance of different endodontic materials used to repair perforations in the furcal area.…”

This study evaluated the retention characteristics of ProRoot mineral trioxide aggregate (MTA), RetroMTA, Supra MTA, and Biodentine biomaterials used to repair furcation perforations contaminated with blood. Furcal perforations measuring 1.3 mm in diameter and 2 mm in height were created in 96 mandibular first molar teeth, which were then randomly divided into the following two groups (n = 48): contaminated (+) or non-contaminated (-) with blood. The groups were subdivided into four groups (n = 12) according to the material used (ProRoot MTA, RetroMTA, Supra MTA, and Biodentine) to seal the perforations. The samples were allowed to set for 14 days and were then subjected to push-out testing. The results were analyzed using ANOVA, and the failure modes were examined using a surgical microscope. ProRoot MTA (+/−) and RetroMTA (+/−) exhibited superior bond strength values; in addition, there were no significant differences among these groups (P > 0.
