Abstract [en]

Objectives: The aim of this study was to investigate the quality of radiographs acquired with digital technique in general dental practices, especially regarding factors related to the display monitor. A further aim was to evaluate how the enhancement programs were used by the dentists. Methods: Nine-teen general dental practitioners were visited in their clinics. Ambient light (illuminance) in the room was measured. Different technical parameters of the display monitor were noted. Test images and two phantoms, one low-contrast phantom and one line-pair resolution test phantom were used to control the digital system. The use of the enhancement program available in their equipment was evaluated by noting how the dentist used the program on a checking list which different functions were used. Results: The average illuminance in the operating room was 668 lux. All monitors were colour. The study showed that the amount of “light percentage” set initially in the monitor had to be decreased with in average 17% to optimise the results of the test images. The contrast factor was decreased with in average 10%. The general dental practitioners mostly used the possibility to alter brightness and contrast of the different phantom images to obtain the subjectively best image Conclusion: There is a need to improve the knowledge how to handle the digital equipment in general dental practice. A monitor with good quality has to be a given priority as well as ambient light conditions when you read radiographs. There is a need to develop a standardised quality control for digital dental radiography.
