“…Whereas, the percentage of regaining patency was 90%, 80%, 90%,100% for group A, B, C and D respectively. The result about regaining WL and patency in this study coincided with some previous studies that reported the WL was regained in 100% of all groups while patency not attainment in all groups.in the study of Oltra et al,2016 patency regained only in 14% of the boiceramic sealers samples and also Carrillo et al,2022 reported that the percentage of regaining patency was 63% in endosequence BC group. This could be imputed to the known fact that the calcium silicate-based sealers become very hard after complete setting, as the Hess et al,2011 reported that the SEM analysis observed the remained bioceramic sealers in the apical foramen and prevented the regaining of patency.…”

Aim: The aim of this study is to evaluate the retreatability of bioceramic sealers (Endosequence BC, Totalfill BC, MTA-Fillapex) used with single cone obturation technique. Materials and methods: Root canal of forty single rooted human mandibular premolar teeth were prepared with ProTaper Next rotary system up to X3 and obturated with single cone technique (n=10) using endosequence BC (A), Totallfill BC (B), MTA-Fillapex (C) and Zinc oxide (D) sealer, after two weeks, all samples retreated with ProTaper Universal Retreatment rotary files. regaining of working length and apical patency was evaluated. All samples longitudinally sectioned and assessed by Scanning electron microscope to evaluate the residual filling materials and the data statistically analyzed. Results: The least amount of residual filling materials was found in group D-ZOE (1.43) followed by group C-MTA-Fillapex (1.50) and B-Totalfill BC (1.57) respectively. While, the greater amount was in group A-Endosequence BC (1.87). Furthermore, the working length was re-gained 100% of all samples.Whereas, the patency regained in group A, B, C and D was 90%, 80%, 90%,100% respectively. Conclusion: None of the root canal filling materials could be completely removed. The greater amount of residual filling materials was observed in bioceramic sealers than the ZOE sealer. Furthermore, the working length regained 100% of samples. While, there was loss of patency in some cases.

“…However, these limitations did not influence the results of this study. [ 9 35 ] Another potential limitation of the study is that the initial preparation size was relatively small, measuring only 25.04. Despite this, the investigation focused on the effectiveness of the retreatment files in removing sealers from within the canals according to the obturation techniques used without any additional preparation.…”

Aim: The aim of this study was to compare the retreatability of NeoSEALER Flo obturated with warm vertical compaction (WVC) and single-cone (SC) techniques using two different retreatment systems. Materials and Methods: Thirty-two root canals were shaped and obturated with NeoSEALER Flo either in an SC obturation technique or a WVC technique. Samples were retreated using ProTaper retreatment or EdgeFile XR retreatment system. The percentage of remaining debris after retreatment was analyzed under a scanning electron microscope using ImageJ software. The time taken to reach full working length (WL) and induce patency was recorded. Statistical Analysis: Statistical analysis was performed using an unpaired t-test and a one-way analysis of variance test. Results: The percentage of remaining debris after retreatment was significantly higher in the SC technique than in the WVC technique, regardless of the retreatment system used. EdgeFile XR system removed more filling material than the ProTaper retreatment system, regardless of the obturation technique. The apical region showed significantly higher remaining debris than other regions in all groups. The WL and patency were achieved faster in the SC group, while in the WVC group, the EdgeFile XR system was faster. Conclusions: The WVC technique showed better retrieval of the filling material; however, a longer time was taken for retreatment. EdgeFile XR system performed better in removing filling materials from inside the canals.

“…As similar to the study of Carrillo et al root canals were cleaned and prepared with EdgeFile X7 (EdgeEndo, Albuquerque, NM) files #20/04, #25/04, #30/04 and #35/04 respectively. 7 Each canal file was replaced with a new one after being used on 5 teeth. During each file change, irrigation was done with 2.5 mL 2.5% NaOCl (Wizard, Rehber Kimya; İstanbul, Türkiye).…”

The aim of this study was to compare the push-out bond strength (BS) of 2 different conventional fiber and glass fiber posts in the form of bundles by using 2 different resin cement and the fracture types formed accordingly. Material and Methods: Root canal treatment was applied to 48 extracted human premolars for the push-out test. The teeth were divided into 3 fiber post groups: Group 1: Biolight ST (conventional fiberpost), Group 2: RelyX (conventional fiberpost), Group 3: Biolight Plus (bundle post) according to the posts to be used for the push-out test. Each of the fiber post groups were divided into 2 subgroups according to adhesive cement [Core-X Flow, Build It FR] used in the cementation of posts (n=8). One mm sections were taken from the middle third of posts and the sections were subjected to a push-out test and the values were recorded. The samples were examined under a stereomicroscope and fracture types were determined. Results: No statistically significant difference was found between the groups according to the test results. When the fracture types were evaluated for all groups, there was no statistically significant difference in the result. Conclusion: The fiber post system in the form of bundles has similar properties with the conventional glass fiber post system in terms of BS.
