Abstract

This study aim is to know the radiation risk in pediatric dentistry, especially using ionizing radiation in computed tomography. Imaging studies that use ionizing radiation are an essential tool for the evaluation of many disorders of childhood. Ionizing radiation is used in radiography, fluoroscopy, angiography, and computed tomography scanning. Computed tomography is of particular interest due to its relatively high radiation dose and wide use. Statements on radiation risk suggest that it is reasonable to act on the assumption that low-level radiation may have a small risk of causing cancer. The best available risk estimates suggest that pediatric computed tomography (CT) will result in significantly increased lifetime radiation risk over adult CT, both due to the increased dose per milliampere-second and the increased lifetime risk per unit dose. Lower milliampere-second settings can be used for children without significant loss of information. Although the risk-benefit balance is still strongly tilted toward benefit, because the frequency of pediatric CT examinations is rapidly increasing, estimates that quantitative lifetime radiation risks for children undergoing CT are not negligible, and may stimulate more active reduction of CT exposure settings in pediatric patients.
