AI Article Synopsis
Article Abstract
Background: The endodontic space is complex, and using a single-cone obturation technique fails to ensure a complete filling.
Introduction: This study aimed to investigate the effect of ultrasonic activation, sonic activation, and single-cone technique of a biosealer on its dentinal tubular penetration.
Materials And Methods: In the experiment, single-root mandibular premolars were randomly assigned to three groups ( = 20): group A, ultrasonic activation; Group B, sonic activation; and Group C, single-cone technique. Penetration of the fluorescently labeled biosealer was investigated using a confocal laser scanning microscope.
Results: The data were statistically analyzed using Kruskal-Wallis and Mann-Whitney tests ( = 0.05). The highest penetration of biosealer was observed in Group A, followed by Group B ( < 0.05).
Conclusions: Dentinal tubule penetration of biosealer was significantly improved by ultrasonic and sonic activation techniques.

In vitro comparison of the marginal adaptation of cold ceramic sealer with the single-cone obturation technique versus AH-26 sealer with the lateral compaction technique in single-canal teeth.

Objectives: This study aimed to compare the marginal adaptation of a cold ceramic (CC) sealer with the single-cone obturation technique with that of an AH-26 sealer with the lateral compaction technique in single-canal teeth.
Materials And Methods: In this in vitro experimental study, the root canals of 24 extracted single-rooted single-canal teeth were instrumented to F3 files by the crown-down technique and randomly assigned to 2 groups (n = 12). The root canals were obturated with a CC sealer and single-cone obturation technique with 4% gutta-percha in group 1 and with an AH-26 sealer and lateral compaction technique with 2% gutta-percha in group 2.
Comparative Analysis of Fracture Resistance of Endodontic Sealer Types and Filling Methods.

With the advent of bioceramic sealers, sealers have become a more important filling material for endodontic treatment. When a solid sealer, rather than an elastic gutta-percha, occupies a significant portion of the root canal, it is unclear whether the tooth structure will be strengthened to withstand stress or whether the increased stiffness will transmit the load directly to the entire root, potentially causing root fracture. This study compared the fracture resistance and fracture patterns of roots filled with various root canal sealers, including bioceramic sealers, and each corresponding filling technique.

This micro-computed tomography (micro-CT) analysis in vitro study was designed to compare void volume in root canal fillings performed using the single-cone (SC) technique and the continuous wave condensation (CWC) technique with bioceramic (BC) sealer. Forty human-extracted, single-rooted mandibular premolars were cleaned, shaped, and divided into two groups (n = 20) based on the obturation technique. In the first group, obturation was performed using the CWC technique with TotalFill HiFlow BC sealer.

Introduction: This study aimed to assess the effect of cavity designs on instrumentation, obturation and fracture resistance for mandibular first premolars with Vertucci V canal.
Methods: Mandibular first premolars with Vertucci V canal were scanned with microcomputed tomography. A total of 20 teeth with moderately curved canal were prepared with conservative endodontic cavity (CEC/M) or traditional endodontic cavity (TEC/M), and 30 with severely curved canal were prepared with CEC (CEC/S), modified CEC (MCEC/S) or TEC (TEC/S).
