Summary: The present study evaluated the effect of ultrasonic agitation on the porosity distribution of root canal fillings used as apical plugs. Results showed that ultrasonic agitation had an impact on the porosity of MTA Flow (MF) fillings, with the MF-UA group showing the highest porosity compared to the other groups.

Summary: The present study assessed the presence of voids in band-shaped isthmuses obturated using three different filling techniques. The results showed that the obturation quality of continuous wave of condensation (CWC) technique was superior to single-cone (SC) and lateral condensation (LC) techniques in the band-shaped isthmus area.

Summary: This study aimed to compare the volume percentage of filling voids in root canals prepared with a newly introduced rotary system, TruNatomy, and obturated by the modified continuous wave (CW) or single cone (SC) filling technique. The results showed that the SC group had a lower volume percentage of filling voids compared to the CW group.

Summary: This study evaluated and compared various root canal obturation techniques on internal root resorption (IRR) cavities using replicated tooth samples manufactured with computer software and a 3D printer. The findings indicated that injectable cold filling and injectable continuous wave obturation systems were more successful in obturating pathological IRR irregularities compared to traditional techniques.

Summary: The aim of this study was to assess the effects of thermomechanical cyclic load on the fracture resistance of lower premolars obturated with AH Plus and BioRoot RCS root canal sealers. The results showed that after thermal-mechanical aging, BioRoot RCS displayed higher fracture resistance compared to AH Plus. Both sealers demonstrated a significant decrease in fracture resistance as the thermal-mechanical cycles increased. This study highlights the importance of considering the aging effect on the fracture resistance of root canal sealers.

Summary: This study aimed to assess the percentage of marginal gaps and voids in oval-shaped canals obturated using two warm compaction techniques with a Bio-C sealer and AH Plus Jet. Microcomputed tomography was used to scan the canines with oval canals, which were then prepared and irrigated. The specimens were divided into four groups based on the filling technique and sealer used. After root canal filling, a new scan was performed, and the percentage of marginal gaps and voids was calculated. The results showed that the Bio-C sealer had significantly lower marginal gaps than AH Plus Jet.

Summary: This study evaluated the biocompatibility of three different root canal sealers (Well-Root St, GuttaFlow Bioseal, and AH-Plus) implanted in rat subcutaneous tissues. Histopathological immunohistochemical analysis showed that all tested sealers had excellent biocompatibility after 30 days, with GuttaFlow Bioseal displaying the least inflammatory reaction.

Summary: This study aimed to assess the interfacial adaptation of two root canal sealers (EndoSequence BC Sealer and AH Plus) to a conventional gutta-percha cone in oval-shaped canals. The results showed that although none of the specimens had a gap-free area along the entire GP-sealer interface, oval canals filled with AH Plus showed fewer gaps than the ones filled with EndoSequence BC Sealer.

Summary: This study evaluated the porosity distribution of root-canal fillings with BioRoot RCS/single gutta-percha point performed by a general dental practitioner and endodontist. The highest number of pores was observed in the apical third of the fillings, with no significant differences in porosity distribution between different root-canal thirds.

Summary: The study aimed to compare the completeness of root canal obturation between cold lateral condensation and warm gutta-percha techniques. It found that both methods produced voids in obturation, with thermoplasticized gutta-percha techniques potentially resulting in fewer voids. However, due to limitations in the included studies, neither technique could completely obturate the root canal.

Summary: This study evaluated the obturation quality of root canals filled with BioRoot RCS sealer and single gutta-percha point by undergraduate students, postgraduate students, and endodontists. The results showed that open pores were the dominant type of porosity in all groups and root canal thirds, with the highest percentage of pores in the apical third. Quality and homogeneity of the fillings were similar in the apical and middle thirds among the groups, but significant differences were observed in the coronal third.

Summary: This study compared the obturated surface area, extrusion of root filling material, and duration of obturation procedure in single-rooted mandibular premolars using a monocone obturation technique. The obturated surface area was comparable at the apical and middle regions between the two groups, but Group 1 showed better coverage at the coronal region by 11.5%. There was no significant difference in the extrusion of root filling material between the two groups, however, the obturation procedure took 8.6% longer in Group 1 compared to Group 2.

Summary: This study investigated the feasibility of re-treating root canal sealers using different types of sealers and at different time intervals after filling. The results showed that calcium silicate-based sealer can be successfully removed after a certain storage time, while epoxy-resin sealer can be removed more quickly.

Summary: The physical properties of TFBC and TFHF were not significantly affected by thermal treatment, while the physical properties of BR were compromised. FT-IR spectroscopy showed no chemical changes in the sealers after heat treatment.

Results showed that MM-Seal had a low voids percentage, and supplementary irrigation techniques did not significantly improve its removal efficacy.
