Outcomes of different radioprotective precautions in children undergoing dental radiography: a systematic review

ConclusionThe following radioprotective measures can reduce the exposure dose.For lateral cephalometry: collimation, filtration, the fastest receptor type and circumstantial thyroid shielding.For oblique lateral radiographs: the shortest exposure time, a smaller horizontal angulation, a longer focus to skin distance.For intraoral radiography: rectangular collimation, the fastest image receptor speed and thyroid shielding when the thyroid gland is in line of or very close to the primary beam.For panoramic radiographs: collimation, the fastest receptor type and the use of automatic exposure control (AEC) or manual adjustment of intensity.For cone-beam computed tomography: collimation, the largest voxels size in relation to the treatment need, change in image settings such as ultra-low dose settings, shorter exposure time, a lower amount of projections, lower beam intensity, reduction of the potential, use of a thyroid shield except in two situations and the use of AEC. All of the changes in exposure parameters should be performed while maintaining a sufficient therapeutic value on an individual and indication-based level.
