Abstract:

Background: Very little research has been performed using anthropomorphic juvenile phantoms and Optically Stimulated Luminescent dosimeters to measure the absorbed doses and energy imparted to children during panoramic and cephalometric radiographic examinations of children. Objectives: To measure juvenile patient radiation dose to the organs of the head and neck during digital panoramic and cephalometric radiography. Methods & Materials: Two juvenile anthropomorphic CIRS phantoms 5 yr old and 10 yr old were filled with Optically Stimulated Luminescent dosimeters at 21 head and neck organ sites. An Instrumentarium OP100D orthopantogramograph was used to expose the phantoms at 73kVp, 6.4mA and 16.8 s for panoramic imaging and at 85kVp, 12mA, and 17.6s for cephalometric imaging. The effective radiation dose was calculated for all the organs of the head and neck. Organ fractions irradiated were determined from ICRP-89. Organ equivalent doses and overall effective doses (micro Sieverts) were based on either one panoramic view or one cephalometric view and the ICRP-103 tissue weighting factors. Results: Overall measured organ doses were higher for the 5 yr old than the 10 yr old for both the panoramic and the cephalometric imaging. The highest doses seen were in the glands, extrathoracic airway and the oral mucosa. The organ equivalent dose in micro Sieverts also yielded similar results. The effective dose in micro Sieverts for the 5 yr old was 27.8 (pan) and 6.5 (ceph), while the 10 yr old results were 26.3 (pan and 3.8 (ceph). Conclusions: This was the first study to evaluate radiation exposure to juvenile CIRS phantoms using OSL dot dosimetry in conjunction with panoramic and cephalometric imaging to provide organ equivalent doses and overall effective dose for 10 yr and 5 yr olds based on ICRP-103 tissue weighting factors.
