Impact of anatomical and clinical variables on the success of endodontic instrument fragment retrieval.

Purpose: Separation of instrument fragments can impede the progress of endodontic treatment, and effective management of this complication is crucial for treatment success. This study examined the factors that impact the success of retrieval of separated instrument fragments by postgraduate endodontic residents.

Methods: A retrospective analysis was conducted on a total of 224 teeth associated with instrument fragment separation that were managed by postgraduate residents specializing in endodontics between January 2020 and March 2024.

Visual Behaviour During the Interpretation of Cone-Beam Computed Tomography Images of Traumatic Dental Injuries: An Eye-Tracking Study.

Background: This cross-sectional observational study aimed to investigate the visual attention patterns of postgraduate endodontic residents during the interpretation of cone-beam computed tomography (CBCT) scans for traumatic dental injuries (TDIs) using eye-tracking technology.

Methods: A cohort of 10 residents who were recruited from King Abdulaziz University Dental Hospital (KAUDH) underwent interpretation of seven CBCT images of TDIs. Eye-tracking metrics, including dwell time, entry time, end time, and the number of revisits, were recorded and analyzed using nonparametric statistical tests.

Radiographic evaluation of teeth with pulp stones and pulp canal obliteration: characteristics, and associations with dental parameters.

The study aimed to radiographically assess the characteristics of pulp stones (PS) and pulp canal obliteration (PCO) in teeth and examined their associations with various dental parameters such as caries, restorations, periodontal status, and age. This cross-sectional observational study was conducted at the Faculty of Dentistry, King Abdulaziz University between September 2022, and May 2023, involved 101 patients exhibiting 402 teeth with PS or PCO. Data were collected from periapical and bitewing radiographs, and analyzed by two calibrated dentists.
