Follow-up radiographs performed by the parallel technique were digitally obtained by photostimulable phosphor plates using DIGORA
OPTIME DXR-60 (SOREDEX, Tuusula, Finland).
All teeth were examined using digital periapical radiographs (PR) (Digora
; Soredex, Helsinki, Finland) in buccal and proximal directions.
Objective: The aim of this study was to compare the accuracy of NewTom 9000 [cone beam computerized tomography (CBCT)], Accu-I-Tomo [limited CBTC (LCBCT)] and Digora
Optime [storage phosphor plate (SPP)] imaging systems in assessing the depths of defects with different shapes and sizes on the proximal surfaces of teeth.
Sizes 1 and 2 PSP (Imaging Plates, Digora
Optime UV, Soredex, Tuusula, Finland) and charge coupled device (CCD) sensors sizes 1 and 2 (Sirona Dental Systems, Benshein, Germany) were used.
The 16-bit data from the VistaScan system were converted into 8-bit data, and the data bits were matched to those from the Digora
Optime and Megadixel systems (Table 1).
Radiopacity of resin-based materials measure in film radiographs and storage phosphor plate (Digora
The sensor, after being exposed, was inserted into the laser optical reader of Digora
for Windows 5.1 software.
The set of plates corresponds exactly to the sensor size from Digora
system (Soredex Orion Corporation, Nilsiankatu, Helsinki, Finland), used for data collection.
The radiographs were digitized and analyzed using the Digora
1.51 software (Soredex, Helsinki, Finland).
"Yes, there are some techniques like the digora
machine used to instantly produce a three-dimensional cad-cam model of a tooth.
