Abstract
This study was aimed at the estimation of the effective doses and radiation risks from dental X-ray examinations based on the data collection in St. Petersburg and the Leningrad Region. The range of mean values of effective doses for intraoral examinations on the X-ray units with film detectors was from 3.5 to 8.2 μSv and for the units with digital detectors-from 1.2 to 2.5 μSv. The mean effective doses for panoramic examinations were 22.9 μSv and for cone-beam computed tomography (CBCT)-530.6 μSv, respectively. The highest detriment-adjusted lifetime risk values were estimated for the 20-24-year-old age group: 40.8×10-6 in females and 32.7×10-6 in males for CBCT. Effective doses in St. Petersburg and Leningrad region were comparable or higher compared with the published data.
