Article Snippet: Manufacturer and technical details , Periapical radiographs: parallelling technique and horizontal angle difference of 10 degrees using an Oralix DC (Gendex Corporation, Milwaukee, WI) dental X-ray machine at 65 kV and 7.5 mA. Film distance: 22 cm and exposure time; 0.32-0.5 s with F-speed films (Kodak Insight; Eastman Kodak, Rochester, NY). CBCT operating parameters were 2.0-4.0 mA, 80 kV, exposure time: 17.5 s using sagittal slices (1 mm thick). Images analyzed by Dell Workstation PWS 350 and Dell monitor (size 18 inches) (Dell, Round Rock, TX) with Trinitron tube, 1,024 x 768 pixels (Sony, Tokyo, Japan) , Periapical radiographs: Max S-1 X-ray equipment (J. Morita Corp., Osaka, Japan) with 0.8 mm x 0.8 mm tube focal spot and with Kodak Insight film (Eastman Kodak, Rochester, NY) using a parallel technique. CBCT images: 3D Accuitomo XYZ Slice View Tomograph (model MCT-1; J. Morita Corp.) voxel size of 0.125 x 0.125 x 0.125mm, 12 or 8 bits. Images examined by 3D Tomo x version 1.0.51. Panoramic radiographs: Veraviewepocs panoramic X-ray unit (J. Morita Corp.) with a 0.5 mm x 0.5 mm tube focal spot with Kodak dental films (T-MAT, 15 x 30; Manaus, Brazil) , Performed , Periapical radiographs: dental X-ray machine (Planmeca Prostyle Intra, Helsinki, Finland) using a digital CCD (Schick Technologies, New York, NY) at 66 kV, 7.5 mA, and 0.10 s using parallel. Small-volume (40 mm 3 ) CBCT scans (3D Accuitomo F170; J Morita Corp.) at 90 kV, 5.0 mA, and 17.5 s, reformatted (0.125 slice intervals and 1.5 mm slice thickness).
