Evaluation of Effective Dose with Two-dimensional and Three-dimensional Dental Imaging Devices

Abstract

ABSTRACT Objectives Different types of X-ray equipment are used in dental radiology. Purpose of this study was to measure the absorbed doses of some critical organs and tissues in head and neck which were exposed by dental imaging devices that are used routinely in dental radiology. Materials and Methods Radiation exposures were performed by using a human equivalent head phantom and dose measurements were determined with thermoluminescent dosimeters (TLD). After exposure of the phantom with dental imaging devices, absorbed and effective doses of critical organs were determined. Results Digital imaging systems produced lower effective doses. Effective doses of cone beam computed tomography (CBCT) and multi-slice computed tomography (MSCT) devices were close to each other. Conclusion Effective doses of digital imaging devices were measured lower than conventional imaging devices. Effective doses of 3D imaging devices were measured higher than all the other imaging devices. However, effective doses of 3D imaging devices were considered in acceptable levels.
