![]() The resulting images were evaluated by three oral radiologists. Exposure was set at 0.12 sec for HRC, 0.08 sec for HSC, 0.16 sec for HRP, 0.12 sec for HRE, and 0.16 sec for the Kodak InSight film. Four combination modes (high-resolution caries mode-HRC high-sensitivity caries mode-HSC high-resolution periodontal mode-HRP and high-resolution endo mode-HRE) were used. All teeth were radiographed with the paralleling technique (60kV, 40 cm focus-to-sensor distance). Of 60 surfaces, 25 had carious lesions in the form of small cavities, and the rest showed no evidence of caries as verified by a micro computed tomogram (micro CT XCT Research SA+, Stratec Medizintechnik GmbH, Pforzheim, Germany). ![]() ![]() Thirty extracted human upper premolars were selected. The purpose of this study was to compare the efficacy of the four combination modes of Trophy RadioVisioGraphy UI sensor (Trex-Trophy Radiology Inc., Marne-la-Valee, France) and Kodak InSight film (Eastman Kodak Co., Rochester, NY) for detecting proximal dental caries. ![]()
