Introduction: The aim of this study was to investigate the applications of cone beam computed tomography (CBCT) amongst endodontic specialists in the United Kingdom (UK) via an online survey.
Methods: An online invitation to take part in the survey was sent out to 306 specialist endodontists registered on the UK specialist register. The survey consisted of a series of questions associated with demographics, access and use of CBCT, utilization of dose optimization parameters, and frequency of use in different clinical scenarios.
Results: In total, 202 respondents completed the survey (a response rate of 66.3%), 128 were male (63.4%), and 74 were female (36.6%). Of the 202 respondents, 174 (85.7%) used CBCT for diagnosis and/or management of endodontic problems. A CBCT scanner was on-site in 71.3% (n = 124) and 28.7% (n = 50) being off-site. A small field of view (FOV) was the prescribed scan in most cases (88.5%, n = 154/174). The cost of the CBCT scan was included in the assessment/treatment fee in 21.8% (38/174) of cases, with 78.2% (136/174) charged a separate fee for the scan. In total, 89.1% (155/174) respondents used CBCT 'often or always' for management of complex root canal anatomy, 87.4% (152/174) for root resorption, 84.5% (147/174) for periapical microsurgery, only 20.7% (36/174) of respondents would use CBCT to assess the outcome of treatment. Only 35.1% (61/174) of respondents would prescribe a CBCT scan for a pregnant patient and 78.2% (136/174) would take a CBCT scan for a paediatric patient. In total, 22.4% (39/174) of respondents did not report or request reports of their CBCT scans. Respondents chose to alter the exposure parameters depending on the patient's age or if the dentition was deemed extensively restored. Of the clinicians who incorporate CBCT into their practice, 93.7% (164/174) believe it improves the quality of the care they provide, and 93.6% (163/174) felt that the use of CBCT improves confidence in their diagnosis.
Conclusions: The use of CBCT amongst specialist endodontists in the UK is commonplace. However, usage does not appear to completely follow best practice guidance for certain clinical scenarios and highlights the need for further training in CBCT.

Objectives: Maxillary transverse deficiency is a common malocclusion frequently observed in orthodontic clinics. Miniscrew-assisted rapid palatal expansion (MARPE) not only produces greater skeletal expansion but also offers advantages such as simple miniscrew implantation without flap elevation, enhanced patient comfort, and an expanded age range and indications for palatal expansion. However, the fixed connection between the expander and the miniscrews makes the expander difficult to remove, significantly hindering its clinical application.

With the ongoing advancement of digital technology, oral medicine transitions from traditional diagnostics to computer-assisted diagnosis and treatment. Identifying dental implants in patients without records is complex and time-consuming. Accurate identification of dental implants is crucial for ensuring the sustainability and reliability of implant treatment, particularly in cases where patients lack available medical records.

Purpose: The multi-modality imaging system offers optimal fused images for safe and precise interventions in modern clinical practices, such as computed tomography-ultrasound (CT-US) guidance for needle insertion. However, the limited dexterity and mobility of current imaging devices hinder their integration into standardized workflows and the advancement toward fully autonomous intervention systems. In this paper, we present a novel clinical setup where robotic cone beam computed tomography (CBCT) and robotic US are pre-calibrated and dynamically co-registered, enabling new clinical applications.

Objective: The aim of this study was to evaluate the mandibular condyle and articular eminences of patients diagnosed with medication-related osteonecrosis of the jawbone (MRONJ) and those who use bisphosphonates (BP) but do not have MRONJ findings, by comparing them with a healthy control group.
Methods: The cone beam computed tomography (CBCT) images of 20 patients (15 male, 5 female) who were diagnosed with MRONJ and 20 patients (16 male and 4 female) who were using bisphosphonates but had no MRONJ were included in the study. A control group consisted of 20 age- and gender-matched patients (13 male, 7 female) who had no clinical complaints or signs and symptoms of TMD or rheumatic disease.
