This study aimed to evaluate the effect of sodium hypochlorite (NaOCl) and ethylene diamine tetra-acetic acid (EDTA) on the bonding and sealing ability of different root repair materials.Methodology: for the push-out bond strength test, ninety dentine discs with 2 mm thickness and a central opening of 1.5 mm were used. The discs were randomly distributed into 3 groups (n=30) based on the repair material used (white MTA Angelus, Biodentine, and Well-Root putty). The materials were condensed inside each disc and allowed to be initially set for 10 minutes. Then each group was further subdivided into 3 subgroups (n=10) based on the irrigant used (NaOCl, EDTA, and no irrigation was used in the 3rd control group) and immersed into the corresponding irrigant for 30 minutes. After complete setting for 72 hours, the bond strength was evaluated with a universal testing machine. For the sealing ability, the same methodology was followed but instead of using dentine discs, we used human-extracted lower molar teeth (n=72) with a standard furcation perforation. After 72 hours, the specimens were subjected to the dye penetration test to assess the sealing ability.Results: Well-Root putty showed the highest bond strength and Biodentine showed the highest sealing ability. Conclusion:NaOCl had a positive effect on the bond strength and sealing ability of both Biodentine and Well-Root putty while the EDTA had a negative effect on the properties of the three tested repair materials.

“…Furthermore, the lack of adverse effects of the application of 2% CHX on the bond strength was reported in other studies [ 77 – 79 ]. While, other studies reported a decrease in bond strength upon application of 2% CHX irrigant [ 8 , 80 , 81 ]. Moreover, Santos et al study was noted a significant reduction in bond strength values when using different concentration of NaOCl combined with 17% EDTA irrigant.…”

Background The aim of this in vitro study was to evaluate push-out bond strength of different root-end filling materials using various irrigant solutions. Methods A push-out bond strength test was performed to evaluate the bond strength of two experimental root-end filling materials: namely, nano-hybrid mineral trioxide aggregate (MTA) and polymethyl methacrylate (PMMA) cement filled with 20% weight nano hydroxyapatite (nHA) fillers compared to conventional MTA. The irrigant solutions employed were sodium hypochlorite (NaOCl) in concentrations 1%, 2.5% and 5.25% and 2% chlorhexidine gluconate (CHX) followed by application of 17% ethylene diamine tetra-acetic acid (EDTA). A freshly extracted sixty single-rooted human maxillary central incisors were used. The crowns were removed, the canal apex was widened to simulate immature teeth. Each type of irrigation protocols was performed. After application and setting of the root-end filling materials, a slice of one mm thickness was cut transversely from the apical end of each root. Specimens were stored for 1 month in artificial saliva and were subjected to a push-out test to evaluate the shear bond strength. Data were analyzed using two-way ANOVA and Tukey test. Results The experimental nano-hybrid MTA showed the highest significant push-out bond strength values when irrigated by NaOCl at several concentrations (1%, 2.5% and 5.25%) (P< 0.05). Meanwhile, irrigation with 2% CHX resulted in highest bond strength values in nano-hybrid white MTA (18 MPa) and PMMA filled with 20% weight nHA (17.4 MPa) with nonsignificant difference between them (p = 0.25). In each root-end filling material, irrigation with 2% CHX led to the highest significant bond strength, followed by NaOCl 1%, while the least significant bond strength was produced after irrigation with NaOCl 2.5% and 5.25% (P< 0.05). Conclusion Considering the limitations of this study, it may be concluded that the application of 2% CXH and 17% EDTA provides superior push-out bond strength to root canal dentin compared with irrigation with NaOCl irrigants and 17% EDTA, experimental nano-hybrid MTA root-end filling material provides enhanced shear bond strength than conventional micron-sized MTA root-end filling material.

Background: Perforation repair materials should have excellent sealing ability and dislodgement resistance. While several materials have been employed for perforation repair, newer calcium-silicate materials, such as Biodentine and TheraCal LC, have shown promising outcomes. Aims: This study aimed to evaluate the effect of different irrigants on the dislodgement resistance of Biodentine and TheraCal LC when used for perforation repair in simulated conditions. Methods and Material: 3% sodium hypochlorite, 2% chlorhexidine gluconate, and 17% EDTA were evaluated for their effect on the dislodgement resistance of Biodentine and TheraCal LC. 48 permanent mandibular molars were selected for the study. The samples were divided into two groups: Group I – Biodentine and Group II – TheraCal LC, with 24 samples each. Statistical Analysis: The mean dislodgement resistance and standard deviation of Group I (Biodentine) and Group II (TheraCal LC) were compared and Failure pattern analysis was done. Results: Biodentine showed a significant decrease in push-out bond strength after contact with 3% NaOCl, 2% CHX, and 17% EDTA whereas, TheraCal LC showed no significant decrease in push-out bond strength after exposure to 3% NaOCl, 2% CHX, and 17% EDTA. Conclusions: Overall, TheraCal LC can be considered good perforation repair material with excellent physical and biological properties.
