Investigation of Patient Dose Received During Digital Dental Radiography and Comparison with International Diagnostic Reference Level (DRL)

IAEA survey of dental cone beam computed tomography practice and related patient exposure in nine Central and Eastern European countries

“…Similar variations between scanners were found in other studies. 21,22 In the study from Endo et al, which included results of P KA from 21 CBCT units, the measured dose ranged from 126.7 mGy cm² to 1476.9 mGy cm. 21 Although European guidelines recommended the adoption an achievable dose of 250 mGy cm² for CBCT imaging appropriate for the placement of an upper first molar implant in a standard adult patient, they also state that large FOV units can exceed this value, as found in the UK's Health Protection Agency preliminary study.…”

“…17,18 Although DRLs have been recognized as a useful tool for optimization of patients radiation protection, their existence for CBCT is still limited, and most published studies of patient doses come from single institutions. [19][20][21][22] With the objective to study the dental CBCT practice and related patient exposure in CBCT in Central and Eastern European countries, a survey was launched in the framework of the IAEA regional technical cooperation project titled "Strengthening Radiation Protection of Patients and Medical Exposure Control". This paper presents the results of this multi national survey.…”
