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.

Objectives: This study evaluates the effect of different irrigation solutions for postoperative pain in the regenerative endodontic treatments (RET) of necrotic teeth with open apex.
Materials And Methods: This study included necrotic, deeply carious lower molars of 42 patients. Access cavities of the teeth were opened and working lengths were measured at the first visit.

Purpose: This study aimed to characterize the 3-dimensional morphology of larger recurved caniniform teeth (LrCTs) and their underlying intraosseous structures in Caprodon schlegelii.
Methods: Specimens (n = 5) with a total length of approximately 32 cm were fixed and processed for micro-computed tomography and/or stereomicroscopy. Volume data of the LrCT-bearing jaws were examined using volume rendering images.

Introduction: Traditional access cavity preparation involves removing the roof of the pulp chamber and smoothing the dentin bulges at the root canal orifice, thereby creating straight-line access. However, this may damage more healthy dental tissue and reduce the tooth's fracture resistance. This case series presents a novel minimally invasive endodontic protocol for one maxillary canine and four mandibular premolars, which required root canal therapy due to labial/buccal cervical decay that caused pulpitis or periapical periodontitis.

Introduction: Endodontic access is often one of the most challenging aspects of treatment, particularly in cases involving locating calcified or missed canals, or when performing selective retreatments of a targeted root. Therefore, the purpose of this study is to compare the accuracy of targeted accesses made using prefabricated grid to those made using freehand techniques with CBCT measurements METHODS: Twenty extracted maxillary molars were mounted into the TrueJaw maxillary model (PlanB Dental, CA). To replicate a clinical scenario where the tooth is extensively restored or has a calcified pulp chamber, the build-up material was intentionally placed directly over the canal orifices.
