The aim of this study was to compare the sensitometric properties of Insight and Ektaspeed Plus radiographic films manually and automatically processed using fresh and depleted chemical solutions. Ten sets of each type of film were obtained (1 set = 5 films), 5 sets being manually processed and 5 sets being automatically processed. A total of 100 films (50 Ektaspeed Plus and 50 Insight film) we...

OBJECTIVES To compare the diagnostic accuracy of conventional film, unenhanced direct digital and inversion grayscale direct digital imaging in the detection of approximal caries. METHODS 150 approximal surfaces of extracted permanent molars and premolars were selected for the study on the basis of varying lesion depth. The teeth were radiographed using Ektaspeed Plus film; digital images wer...

BACKGROUND AND AIM: The purpose of this study was to evaluate the sensitometric characteristics of Ultraspeed, Ektaspeed Plus and Insight dental radiographic films using manual and automatic processing systems. METHODS: In this experimental invitro study, an aluminum step-wedge was used to construct characteristic curves for D-, Eand F-speed radiographic films (Kodak Eastman, Rochester, USA). A...

OBJECTIVE To establish optimal exposure parameters for lateral oblique radiographs of rat mandibles using an intraoral X-ray machine. METHODS A positioning apparatus, previously tested for its reproducibility, was used to obtain radiographs of four heads of formaldehyde-preserved Wistar rats. Radiographs were exposed at 50 kV and 8 mA using four size 2 films (Insight, Ektaspeed Plus, Ultraspe...

Six test dental radiographic films with varying resolutions and exposure times were evaluated diagnostically by 334 dentists. Each dentist completed a questionnaire relative to observations, dental education, practice profile, film utilization, and opinions on how electronic enhancement of the film affected his diagnostic ability. More than 60% identified 12-20 paired lines per mm of resolution...
