“…Group 1 (EDTA/MTA) had higher sealing ability than Group 2 (EDTA/iRoot BP), and Group 3 (laser irradiation/MTA) had higher sealing ability than Group 4 (laser irradiation/iRoot BP). Consistent with the findings of previous studies 19,24) , our results based on fluid filtration method showed that iRoot BP did not provide a better seal than MTA.…”

Effect of Er,Cr:YSGG laser irradiation on apical sealing ability of calcium silicatecontaining endodontic materials in root-end cavities

et al. 2014

The aim of this research was to evaluate the apical sealing abilities of 60 root-end cavities filled with mineral trioxide aggregate (MTA) and iRoot BP cements after treated with either 17% EDTA solution or Er,Cr:YSGG laser irradiation. After the filling procedure, apical leakage quantity was measured at 4 weeks using a fluid filtration method. One root from each group was processed for scanning electron microscopy and energy dispersive X-ray spectroscopy analyses. Both EDTA/MTA and laser irradiation/MTA combinations showed significantly lower microleakage than EDTA/iRoot BP and laser irradiation/iRoot BP combinations (p<0.05). Between groups of the same filling material, there were no significant differences among specimens treated with EDTA or laser (p>0.05). Both MTA and iRoot-BP demonstrated tag-like structures within the dentinal tubules when used in conjunction with EDTA.

“…Recent studies on calcium silicate-containing biomaterials showed that they yielded comparable results to MTA, and the authors also concluded that these biomaterials offered no apparent advantages over MTA 19,24) . In the present study, comparison of groups with the same smear layer removal method yielded the same results.…”

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.

Aim: The aim of this study was to evaluate the fracture strength (FS) of bovine incisors with simulated incomplete rhizogenesis (IR) after different intraradicular treatments. Materials and methods:Incomplete rhizogenesis was simulated by sectioning the crowns and roots of 40 bovine incisors. Root canal preparation was performed and the samples divided into 4 groups (n = 10): GI-negative control with intra-radicular preparation; GII-positive control without intra-radicular preparation; GIII-glass fiber post cemented with resin cement and GIVroot canal obturation with Epiphany/Resilon system. In GIII and GIV, 4.0 mm apical plugs of mineral trioxide aggregate (MTA) were done. The samples were embedded into cylinders with polystyrene resin, and the periodontal ligament was simulated with a medium-viscosity polyether-based impression material (Impregum Soft). The specimens were submitted to compressive fracture strength test (0.5 mm/min at 135º in relation to the long axis of the tooth) in a mechanical testing machine MTS 810. Data were submitted to ANOVA and Tukey's test (α = 0.05).Results: GIII produced the highest FS values (p < 0.05). GI and GIV showed similar FS results (p > 0.05) but smaller than GII (p < 0.05). Conclusion:Glass fiber intraradicular posts provided the FS increase of teeth with simulated incomplete rhizogenesis. Epiphany/Resilon root canal filling with MTA plug did not provide the increase of the fracture strength to teeth with simulated incomplete rhizogenesis. Clinical significance:The fiber post reinforces the root structure of teeth with incomplete rhizogenesis.
