Introduction CBCT is an emerging radiographic imaging modality associated with an effective radiation dose that is generally higher than conventional radiography. The diagnostic benefit must exceed the individual detriment that radiation exposure may cause. Particularly true in the paediatric patient who is more susceptible to stochastic biological effects. There are few studies investigating the use of dental CBCT in children and its impact on management. Aim Ensure the judicious use of CBCT in paediatric patients. Objectives A service evaluation to determine the proportion of paediatric patients being referred for CBCT, to review the reasons for referral and evaluate the influence of CBCT on treatment plans. Method Retrospective data was collected from the CBCT daybook for all paediatric patients who underwent a CBCT scan from Nov 2018 to Nov 2019. Clinical records were reviewed to identify the reason for referral and its influence on diagnosis or management, by comparing the provisional treatment plan, prior to CBCT referral with the definitive treatment plan, post-CBCT. Results 130 patients underwent CBCT in this period, of which 52 were internal referrals. This equates to 0.8% of all paediatric patients seen in the department over the same period. CBCT was most commonly requested to assess root resorption (n=15, 29%); surgical planning (n=13, 25%) and to assess the position of supernumerary teeth (n=12, 23%). The remaining 23% of cases were referred to assess bony disease, position of unerupted/impacted teeth, pupal anatomy and root fractures. 100% of CBCTs provided information that assisted treatment planning, diagnosis or management. Most significantly, 38% (n=20) of treatment plans were changed because of information provided by CBCT. Conclusion All CBCTs requested were justified and confirmed or influenced the management of paediatric patients, ultimately reducing the risk of complications and further treatment.
