Cone beam computed tomography - Frequency and exposure settings at University (Dental) hospitals in Central and Northern Europe.

Purpose: To investigate the frequency of CBCT scans, the exposure settings, volume sizes and the patient demographics (age and sex) of patients undergoing CBCT scans in university-based dental hospitals in different European countries over a one-year period.

Method: Eight University Dental Hospitals from eight countries in central and northern Europe agreed to collect data from their CBCT-databases. Exposure data including field of view (FOV), dose area product (DAP) and optimization settings plus (anonymous) age and sex of the patients were collected for the entire year 2023.

Portable X-ray fluorescence of zinc and selenium with nail clippings-Mother and Infant Nutrition Investigation (MINI).

Zinc and selenium are essential minerals for human nutrition. Reliable biomarkers of zinc status and selenium status in humans are therefore important. This work investigates a novel portable X-ray fluorescence (XRF) method with the ability to rapidly assess zinc and selenium in nail clippings.

A survey of patient contact shielding in dental teaching hospitals in the UK.

A high volume of dental imaging is carried out each year. In the UK, guidance on the use of patient contact shielding for these investigations is published by the British Institute of Radiology (BIR) and in a document jointly produced by the Faculty of General Dental Practice and Public Health England (FGDP/PHE). Both these sources of guidance have been updated recently and patient contact shielding is no longer recommended for most imaging settings in dental radiology.

Cone-beam computed tomography and its applications in dental and maxillofacial radiology.

Cone-beam computed tomography (CBCT) was first used in dental and maxillofacial radiology (DMFR) at the end of the 1990s. Since then, it has been successfully established as the standard three-dimensional radiographic imaging technique in DMFR, with a wide variety of applications in this field. This manuscript briefly reviews the background information on the technology and summarises available data on effective dose and dose optimisation.

Dental and maxillofacial radiology: confidence, knowledge and skills in the newly graduated dentist.

Introduction The UK General Dental Council says that the new graduate will have the range of skills required to begin working as part of a dental team and be well-prepared for independent practice. This study examines the views of new dental graduates in the area of dental and maxillofacial radiology.Materials and methods A questionnaire survey of newly graduated dentists in Wales and South West England asked about their experience of undergraduate education in dental and maxillofacial radiology, and their confidence in the use and interpretation of imaging techniques in early independent practice.
