Table 1 Effective dose from conventional dental imaging techniques (i.e. intraoral, panoramic and cephalometric radiograph), cone beam computed tomography (CBCT) and multislice computed tomography (MSCT) in μSv. The range of the effective dose and median values (in parentheses) from dental CBCT in μSv (according to the Tables by EC 2012 [6]). For comparison, in Finland the annual radiation dose is approximately 3,200 μSv, i.e. approximately 10 μSv/day [10]
