“…The present study showed that there was no significant difference in the push out BS of the cements when the final irrigant was NaOCl or CHX. This is in contrast to the results of Hong et al [20] This difference may be due to two reasons-the reported study immersed the cement samples in the irrigants after an initial set of 10 min and, the bond strength was analyzed after 48 h.…”

“…However, irrigation of the root canal with NaOCl is another factor that has been found to affect bond strength, providing significantly greater push-out strength with MTA than with chlorhexidine gluconate. 34 To replicate clinical practice, teeth were treated with NaOCl in this study. Further studies of the bond strength of MTA to dentin with the use of different irrigation solutions are needed.…”

This study evaluated the bond strength of mineral trioxide aggregate (MTA) to root canal dentin after the performance of various irrigation procedures to remove triple antibiotic paste (TAP). A total of 56 single-rooted human mandibular premolars were instrumented using a rotary system to size 40 and divided randomly into a control group (no intracanal dressing) and three experimental groups (TAP application for 28 days). TAP was then removed by rinsing with 10 mL 2.5% NaOCl using three irrigation systems (Vibringe sonic irrigation, CanalBrush, and syringe irrigation). The coronal and middle parts of root canals were then obturated with MTA. After storage for 1 week, each specimen was embedded in an acrylic block and sectioned horizontally (2-mm-thick slices) at two levels (coronal and middle). Bond strength of MTA to root canal dentin was assessed in 28 samples per group via push-out test using a universal testing machine. Data from the four groups were compared using one-way analysis of variance. Tukey's test was used for multiple comparisons. Push-out bond strength values were significantly higher in the control and Vibringe groups than in the CanalBrush and syringe irrigation groups (p < 0.001). TAP removal from root canals with the Vibringe irrigation system may increase the push-out bond strength of MTA compared with the use of the CanalBrush or syringe irrigation.

“…For hydraulic cements such as MTA, surface microhardness depicts the degree of hydration that occurred during the setting process and the influence of the setting environment on the overall strength of the material [13] . However, push-out bond strength testing is a practical and reliable method to evaluate the adaptation of a material to its surrounding root dentin [14] . A few studies [6,15,16] have evaluated the push-out bond strengths of MTA, Biodentine, and BioAggregate, but no report has compared all 3 of these materials.…”

of 1 mm/min. Samples were analyzed under a light microscope to determine the nature of bond failure. Ten samples (2 mm thick) were prepared for all the materials, and Vickers microhardness was determined using a digital hardness tester. Data were analyzed using one-way analysis of variance and Tukey-Kramer multiple comparison tests at a significance level of p < 0.05. Results: Biodentine (42.02; 39.35 MPa) and ProRoot MTA (21.86; 34.13 MPa) showed significantly higher bond strengths than BioAggregate (6.63; 10.09 MPa) in coronal and apical root dentin, respectively ( p < 0.05). Biodentine also differed significantly from ProRoot MTA in coronal dentin. Bond failure was predominantly adhesive in Biodentine and ProRoot MTA, while BioAggregate showed predominantly mixed failure. ProRoot MTA (158.52 HV) showed significantly higher microhardness and BioAggregate (68.79 HV) showed the lowest hardness. Conclusion: Biodentine and ProRoot MTA showed higher bond strength and microhardness compared to BioAggregate. AbstractObjective: This was an in vitro evaluation of push-out bond strength and surface microhardness of calcium silicatebased biomaterials in coronal and apical root dentin. Materials and Methods: Ninety sections (2 mm thick) of coronal and apical root dentin were obtained from roots of 60 extracted teeth; the canals were enlarged to a standardized cavity diameter of 1.3 mm. Sections were randomly divided into 6 groups ( n = 15 per group), and cavities were filled with Biodentine TM , BioAggregate, or ProRoot mineral trioxide aggregate (MTA), according to the manufacturers' instructions. Push-out bond strength values were measured using a universal testing machine under a compressive load at a speed Significance of the StudyIn this study, the push-out bond strength and microhardness of 3 materials, ProRoot MTA, Biodentine, and BioAggregate, were compared. Biodentine and ProRoot MTA had higher bond strength and microhardness values than BioAggregate, and hence could be the materials of choice for root repair procedures and retrograde fillings.
