OBJECTIVE: To investigate access to, frequency of use, justification, challenges and training regarding cone-beam computed tomography (CBCT) imaging in orthodontics in the UK.
DESIGN: Cross-sectional questionnaire study.
SETTING: Web-based.
METHODS: An online questionnaire was developed after a review of the literature and discussion with practising orthodontists to identify key themes of importance. It was piloted before use and then distributed via the British Orthodontic Society (BOS). All responses were anonymous.
RESULTS: A total of 82 complete responses were received (~7% response rate). Access to CBCT facilities was primarily through NHS secondary care (68%). Usage was mainly for assessment of impacted teeth, and 80% of respondents who use CBCT reported increased CBCT imaging referrals over the past 5 years. Barriers included geographic distance and cost. Almost 60% of respondents had formal CBCT training, but over one-third lacked easy access to dental/maxillofacial radiology reporting.
CONCLUSIONS: Access to CBCT for orthodontic patients in the UK was mainly through NHS secondary care. Most respondents reported using CBCT for fewer than 10% of patients, most commonly for assessment of unerupted or impacted teeth. The majority of those who used CBCT reported an increase in CBCT referrals over the past 5 years. Reported challenges included cost, travelling distance to CBCT facilities, and limited access to dental and maxillofacial radiology reporting. Although most respondents had undertaken formal CBCT training, over one-third reported difficulty accessing specialist radiology support.
