Effective dosages for recording Veraviewepocs dental panoramic images: analog film, digital, and panoramic scout for CBCT

ObjectiveThe aim of this study was to evaluate the effective doses from analog film, panoramic digital, and panoramic scout for cone-beam computerized tomography (CT).Study designThree different types of Veraviewepocs machines were investigated: Veraviewepocs Conventional, Veraviewepocs Digital, and Veraviewepocs 3D (Morita, Kyoto, Japan). Organ absorbed doses were measured using an anthropomorphic phantom loaded with thermoluminescent dosimeters (TLD 100H) at 16 sites located in sensitive organs. The resulting effective organ doses (μSv) were compared by descriptive statistics.ResultsThe highest value (5.2 μSv) was for Veraviewepocs Conventional. The Veraviewepocs Digital (2.7 μSv) and Veraviewepocs 3D (2.95 μSv) presented low effective doses in the same range.ConclusionsThe panoramic digital system delivered the least radiation dose. The use of the panoramic scout for cone-beam CT was marginally higher in dose than its 2D counterpart.
