Introduction. Cone beam computerized tomographies (CBCTs) are increasingly being employed, as a diagnostic tool, on orthodontic patients, as these systems provide an alternative to conventional x-rays and computed tomography (CT). Aims. To compare the radiation doses of the different diagnostic systems and to set out the parameters to be considered when assessing the radiation patients can be exposed to. Conclusions. Despite several studies already existing on this issue, the radiation that these CBCT systems generate must continue to be carefully studied, as, to date, their radiation is significantly higher than conventional digital x-rays, and hence their use must be fully justified.  (Rev Esp Ortod. 2011;41(1):017-022)
