Summary: This study compared the effectiveness of ultrasonic vibration and thermo-hydrodynamic obturation (VibraTHO) using two different root canal sealers with the single-cone technique and a calcium silicate-based root canal sealer in complex root canal anatomies. The results suggest that the VibraTHO technique using GuttaFlow 2 may be more suitable for anatomically complex root canal systems, while the VibraTHO technique using Endoseal TCS has limited impact on improving root filling quality.

Summary: The study evaluated modifications in root canal sealers under different heating conditions using vibrational spectroscopy and chemical analysis. Heating significantly changed the flowability and solubility of calcium silicate-based sealers, with AH Plus being the only stable sealer after heating. Calcium silicate-based sealers exhibited high solubility, raising concerns for their clinical use.

Summary: The impact of calcium silicate-based sealer insertion technique on void occurrence and sealer extrusion during single-cone obturation was assessed using micro-CT. Results suggest that sonic and ultrasonic activation might help reduce void occurrence, highlighting the potential benefit of calcium silicate-based sealer activation in wide and oval root canals for improving the quality of single-cone obturation.

Summary: The study aimed to evaluate the obturation efficacy of different techniques using microcomputed tomography (mu CT). Incisors and molars were scanned using mu CT and 3D printed in acrylic. Different obturation techniques and sealer types were assessed, and the effect of mu CT testing parameters was investigated. The results showed that BioRoot RCS, Totalfill BC, and Bio-C Sealers are suitable for obturation, and 3D printed teeth can be used to assess obturation quality in simple root canal systems.

Summary: This study evaluated the outcomes of endodontic microsurgery (EMS) using different retrograde filling materials. The results showed high success rates when using MTA, RRM putty, or lid technique as root-end filling materials, and CBCT imaging was more precise in detecting the healing outcomes of EMS.

Summary: The study evaluated the influence of artefacts on CBCT images of filled root canals in isthmus-containing molars, finding that different artefacts compromise the detection of filling voids. While ACC and NT showed rather similar diagnostic accuracy, artefact expression remains device-specific.

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 quality of root canal filling has an impact on the status of periapical lesions. The absence of gaps in the filling and an apical filling extension of 0-2mm below the apex can reduce the occurrence of unhealed periapical lesions.

Summary: This study evaluated the efficiency of SWEEPS in removing epoxy-resin-based and calcium-silicate-containing endodontic sealers in combination with single-cone and carrier-based obturation techniques. The results showed that SWEEPS significantly reduced the volume of root canal filling materials in all experimental groups compared to using only reciprocating instruments (p < 0.05). However, complete removal of the root canal filling was not achieved. Therefore, SWEEPS can be used to enhance the removal of these sealers, but further improvements are needed.

Summary: The study compared the effects of different pulp capping materials on the viability and odontogenic differentiation of human dental pulp stem cells, finding that all materials except Dycal were favorable for hDPSC viability. ProRoot MTA and TheraCal LC showed higher expression of Runx2 compared to Biodentine, indicating their potential in promoting odontogenic differentiation. Future studies should further explore the odontogenic potential of pulp capping materials.

Summary: The study found that taurine and ginseng extract can reduce oxidative stress levels in cells, enhance oxygen uptake and lipid metabolism in mice, and effectively fight against fatigue. After oral administration of ginseng extract alone for 30 days, mice had longer swimming times, but there was no synergistic effect with the combination of taurine and ginseng extract.

Summary: The aim of this study was to determine the osteogenic and dentinogenic potential of commercially distributed MTA and HCSCs when applied in combination with Emdogain gel on human dental pulp stem cells (hDPSCs). The presence of Emdogain resulted in greater cell viability, and higher alkaline phosphatase activity was detected in the Emdogain-supplemented groups in the early days of cell culture. Overall, the cytotoxicity and osteogenic/odontogenic potential of HCSCs were similar to that of ProRoot MTA.

Summary: This study aimed to compare the incidence of periodontitis according to menopausal status and investigate the potential effect of hormone replacement therapy (HRT) on periodontitis in postmenopausal women. The results showed that postmenopausal women had a significantly higher risk of periodontitis compared to non-menopausal women, and the use of HRT in postmenopausal women could reduce the incidence of periodontitis.
