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

Objective. The 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 design. Three 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 (mu Sv) were compared by descriptive statistics. Results. The highest value (5.2 mu Sv) was for Veraviewepocs Conventional. The Veraviewepocs Digital (2.7 mu Sv) and Veraviewepocs 3D (2.95 mu Sv) presented low effective doses in the same range. Conclusions. The 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. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2008;106:571-7)
