Summary: This in vitro study evaluated the push-out bond strength of different root-end filling materials using different irrigant solutions. The experimental nano-hybrid MTA showed the highest bond strength when irrigated with different concentrations of NaOCl. Irrigation with 2% CHX resulted in the highest bond strength values for both nano-hybrid white MTA and PMMA filled with 20% weight nHA.

Summary: This study evaluated the influence of different canal drying protocols on bond strength and interface quality of roots filled with BCS and AHP. The results showed that the best drying protocol for AHP was using the White Mac tip followed by capillary tip aspiration and paper points until complete dryness, while for BCS it was using the White Mac tip followed by capillary aspiration without paper points.

Summary: Calcium silicate-based materials have gained popularity as root canal sealers due to their biocompatibility, antimicrobial properties, and certain bioactivity, but their higher solubility may impact their long-term sealing ability. Unlike conventional sealers, these sealers are hydraulic and require humidity for setting. Limited research has been conducted on the clinical outcomes of calcium silicate-based sealers, with current usage mainly based on clinical practices rather than recommendations or evidence.

Summary: The aim of this study was to evaluate the effect of a novel root canal sealer based on bioactive glass (BG) on root fracture resistance and explore its mechanism. The results showed that the BG sealer had good physicochemical properties, formed stable bond with dentin, and increased root fracture resistance. Therefore, this novel root canal sealer has important clinical application value.

Summary: The study compared the bond strength of epoxy resin-based sealer with two calcium silicate-based sealers to gutta-percha discs. Results showed that the epoxy resin-based sealer had significantly higher shear bond strength values compared to the calcium silicate-based sealers. The proposed methodology was found to be innovative and reproducible for testing the bond strength of root canal sealers to gutta-percha.

Summary: This study compared the penetrability and bond strength of two calcium silicate-based sealers and an epoxy resin-based sealer, as well as examined the relationship between penetrability and bond strength for the different sealers. The results showed that regardless of the location in the canal, the bioceramic-based root canal sealers appeared to perform better than the epoxy resin-based sealer in terms of dentinal penetration rate. Further studies are required to compare other biomechanical properties of bioceramic sealers including setting characteristics and bacterial leakage.

Summary: In this experimental study, push-out tests were conducted to evaluate the shear strength of louver steel plates with different types of shear connectors. It was found that the use of louver steel plates increased the shear strength of the specimens compared to plain steel plates, and the increased strength was approximately 88% of the theoretical bearing strength of the louvers. The slip capacity of the headed studs satisfied the specified criteria, while the lattice shear connectors did not due to insufficient welding length.

Summary: Shaping ability of taper .01 instruments in large root canals was evaluated using micro-CT and SEM. XP-Endo Shaper showed less dentinal wear compared to manual instrumentation. Roundness and SMI were similar between both protocols. Reduced diameter and taper instruments promoted conservative wear and well-defined apical stop formation in large root canals.

Summary: This study evaluated the physicochemical properties of endodontic sealers containing dry or diluted rhodamine B. The results showed that dry rhodamine decreased bond strength and prolonged the setting time of AH Plus, while diluted rhodamine decreased setting time and increased flowability of MTA Fillapex. The incorporation of rhodamine also caused pH reductions in both sealers. Overall, diluted rhodamine changed the properties of MTA Fillapex, and dry rhodamine changed the properties of AH Plus.

Summary: The present study developed a method to induce incomplete root fracture in human extracted teeth for evaluating different diagnostic imaging techniques. The method involved removing tooth crowns, preparing root canals, and applying a customized conical wedge with a specific force to induce fractures. The method was successful in producing fractures that resembled clinical presentation. It is a reproducible and reliable method for laboratory studies on vertical root fractures.

Summary: The aim of this study was to investigate the association between single nucleotide polymorphisms in nitric oxide synthase and persistent apical periodontitis. The results showed that the genotype and allele distributions were not statistically significant between the persistent apical periodontitis and healed groups. Therefore, this study did not find an association between single nucleotide polymorphisms and persistent apical periodontitis.

Summary: The study evaluated the effects of temporary restorative materials on antibiofilm and antimicrobial activity in root canals after an intra-oral challenge. Different materials were applied to treated roots and compared based on their ability to inhibit biofilm and bacterial penetration. High-viscosity glass ionomer and light-activated glass ionomer showed the strongest antibiofilm properties, followed by zinc-oxide cement without eugenol and zinc-oxide cement with eugenol. Unsealed roots had the highest biofilm accumulation and bacterial penetration compared to restored roots.

Summary: The aim of this study was to identify the most effective supplementary protocols used during endodontic reintervention for removing remaining filling material (FM). After a literature search and qualitative analysis of 46 articles, various supplementary protocols such as sonic and ultrasonic activation, ultrasonic inserts, and new devices were found to be effective in removing remaining FM, although complete removal was not always achieved. Combining these protocols can enhance FM removal and improve the cleaning and disinfection of root canals.

Summary: The purpose of this study was to evaluate the effect of laser on root canal disinfection and periapical healing in patients with asymptomatic apical periodontitis. A randomized clinical trial was conducted with 30 patients, where 15 patients received root canal retreatment (RCR) combined with 980-nm diode laser irradiation (LI), and the other 15 patients received RCR with placebo irradiation (PI). Microbiological samples were taken at different time points and analyzed for microbial reduction. Periapical radiographic healing was evaluated at different follow-up periods. The results showed that the laser had a significant antimicrobial effect and improved periapical healing compared to the placebo group.
