Dosimetry Comparison of CBCT versus Digital 2D Orthodontic Imaging in a Pediatric Orthodontic Patient
Journal Title: Journal of Dental Health and Oral Research - Year 2021, Vol 2, Issue 2
Abstract
The purpose of the study was to evaluate the amount of radiation potentially absorbed by a pediatric patient during whole-head (13x15 cm) CBCT imaging compared with digital panoramic and lateral cephalometric imaging using the same machine. For each of the three imaging modalities, twenty-one nanoDot Optically Stimulated Luminescent Dosimeters (OSLDs) were placed in a pediatric anthropomorphic 10-year old phantom in order to record absorbed radiation doses at different radiosensitive locations. All imaging was performed using the manufacturer’s recommended exposure settings. Ten more runs were performed with an OSLD placed only at the thyroid. A Monte Carlo Analysis was performed to extrapolate the absorbed doses for the remaining twenty organ locations. Equivalent doses for the head and neck organs and overall effective doses was determined using the International Commission on Radiological Protection’s tissue weighting factor guidelines. For each of the organs tested, there was a statistically significant differences in radiation doses across the three imaging modalities. The highest radiation doses were observed in CBCT imaging for all organs. The average effective dose was higher in CBCT than in lateral ceph and panoramic imaging combined. The results of the study suggest that in order to reduce pediatric patient radiation exposure during routine orthodontic records, conventional 2D imaging with digital panoramic and lateral cephalometric modalities should be used preferentially over CBCT imaging.
