“… 8 In the present investigation, no patient under 6 years of age was seen, corresponding to previous investigations. 9 10 This situation is in accordance with the principle of justification, since a CBCT examination may not be necessary in patients under 6 years of age, because it may not be possible to clinically intervene in patients in this age group.…”

“… 8 Two recent studies have evaluated the use of CBCT in children in different populations. 8 9 Both studies found that most CBCT examinations were performed with a small field-of-view (FOV), which implies that this aspect of optimization had been performed properly. However, Hidalgo-Rivas et al 8 did not find any statistically significant difference between radiation doses in the age groups studied.…”

PurposeTo analyze cone-beam computed tomography (CBCT) use, indications, and exposure parameters in San José, Costa Rica.Materials and MethodsA cross-sectional study was performed. All CBCT examinations over a period of 6 months at 2 radiological centers in San José, Costa Rica were evaluated. The examinations were performed with Veraview EPOC X550 and Veraviewepocs 3D R100 equipment. The patients' age and sex, clinical indication for CBCT, region of interest (ROI), repeat examinations, specialty of the referring dentist, field-of-view (FOV), tube voltage (kV), tube current (mA), and radiation dose (µGy) were evaluated. Patients were classified by age as children (≤12 years), adolescents (13–18 years), and adults (≥19 years).ResultsThe mean age of the 526 patients was 49.4 years. The main indications were implant dentistry and dental trauma. The most frequent ROIs were posterior, while anterior ROIs were much less common. The highest percentage of repeat examinations was in children. Fifty-six percent of the referring dentists were specialists. The most commonly used FOV was small. The mean tube voltage and current were 79.8 kV and 7.4 mA for Veraview EPOC X550 and 89.9 kV and 6 mA for Veraviewepocs 3D R100, respectively. The mean doses for children, adolescents, and adults were 6.9 µGy, 8.4 µGy, and 7.8 µGy, respectively.ConclusionAlthough CBCT was most commonly used in adults for implant dentistry, most repeat examinations were in children, and the highest mean dose was in adolescents. Additional dose optimization efforts should be made by introducing low-dose protocols for children and adolescents.

“…The images used in this database belong to a dataset that was originally collected for a retrospective observational study: material and methods for image selection and some selected results will be shown here. 18 One main investigator (JVA) made a hand search in the Planmeca ® database (Romexis ® ) for all patients under the age of 18 years who underwent a CBCT scan over a period of 2 years from the installation of the CBCT unit in the dental out-patient clinic of the University Hospital Ghent in Belgium. In this period, the CBCT-unit was a Planmeca Promax ® 3D Max.…”

“…No images had to be retaken; there were three images with artefact reduction. Descriptive statistics concerning patient gender, age group, distribution of FOV, distribution of resolution, internal/external referral and reason for referral as well as their corresponding correlations can be found in the article by Van Acker et al 18 There were eight main reasons for referral. For the 79 CBCTs, 107 reasons for referral were found, since some CBCTs demonstrated to be referred for multiple reasons at the same time.…”

Objectives: The main objective of this study was to perform a retrospective reject analysis (or audit) of 79 cone-beam CTs (CBCTs) taken in under-aged patients at the Ghent University hospital over a 2-year timespan. Methods: Observer agreement between two oral radiologists and two senior year Master students in Paediatric Dentistry was performed for quality, diagnostic and therapeutic value. The senior year Master Students followed appropriate modules of an online course. Descriptive and comparative statistics were performed. Results: For the oral radiologists, all intra rater reliabilities were moderate to good (Gwet's AC1 = 0.41-0.75). For the senior students in Paediatric dentistry, these varied highly from fair to very good (Gwet's AC1 = 0.28-0.95). There was a high level of disagreement between oral radiologists and students (Gwet's AC1 = 0.16-0.45) and in-between students concerning observed quality (Gwet's AC1 = 0.29). A total of 16 CBCTs (20%) was rejected, 24 images (30%) were acceptable and 39 images (50%) had an excellent quality. 50 CBCTs were perceived to have a diagnostic advantage. 13 of the images would have no influence on the therapy, according to the oral radiologists. A significant correlation was found between unacceptable quality, absence of perceived diagnostic advantage (p = 0.004, RR = 2.4) and influence on therapy (p < 0.0005, RR = 1.8). A small field of view (FOV) was positively correlated to an excellent quality of the image (p = 0.011, RR = 2.8). conclusions: Image quality did not reach the proposed boundary of 10% according to the European Guidelines on Radiation Protection in Dental Radiology. This is the first published audit on an overall database of under-age children for CBCT.
