Research summary
This research aims to investigate orthodontic clinicians' practices and perceptions of Cone Beam Computed Tomography (CBCT) imaging. This is a relatively novel form of 3D radiographic imaging designed specifically for use in the craniofacial region (head, jaw bones, teeth) to aid diagnosis and treatment planning. There is wide variation in practices, especially with regards to reporting on these how both orthodontists (dental specialists who diagnose and treat disorders of the jaws and teeth) and patients feel about a type of 3D X-ray called Cone Beam Computed Tomography (CBCT), which is frequently used in orthodontic treatment planning.
The study is split into two main parts. The first part focuses on UK orthodontists. It will explore their knowledge, experiences, and any challenges they face when using and reporting on CBCT scans. This includes whether they have received enough training, how confident they feel reporting on CBCT, and how well they follow professional guidelines. Researchers will first speak with orthodontists in small discussion groups to gather detailed insights. Then, a national questionnaire will be developed and utilised on a wider group to expand on the findings.
The second part of the study looks at patient experience. It aims to understand how patients feel when they are asked to have a CBCT scan as part of their orthodontic care. The research will explore whether patients feel anxious or comfortable during the scan, and how well the procedure was explained. It will also assess how much information patients receive before, during, and after the scan.
By gathering views from both orthodontists and patients, the study hopes to identify ways to improve training for clinicians, ensure CBCT is used appropriately, and enhance communication and care for patients. This research could help support safer, more informed use of CBCT imaging in orthodontics across the UK.
