Original Article Subjective image quality comparison between two digital dental radiographic systems and conventional dental film

Digital radiography is an integral part of dentistry. Digital radiography does not require film or darkroom, reduces x-ray doses, and immediately produces images. Our research aims to compare the subjective image quality of the two digital dental radiography systems with the conventional dental film.

We have selected Sirona's Direct Digital (DD) "Digital" system, Vista-scan's Semi-Direct (SD) digital system, and Kodak's "E" Speed ​​Dental X-ray film for this research. In this study pulp-treated extract (n = 25) was used. Details of enamel, dentin, dentin-enamel junction, root canal filling (dental tip) and simulated apical pathology were investigated using three X-ray imaging systems. Statistical analysis of data to clarify the difference in subjective image quality

Traditional dental x-ray film is superior to digital system. In digital systems, DD imaging is superior to SD imaging.

Traditional films produced superior image quality and were statistically significant in almost all comparisons. By tracking the image quality of traditional movies via DD, SD provides the lowest quality images. Traditional movies are still considered gold standards to diagnose diseases that affect the tibia

Improved software and hardware for digital imaging systems are currently available and these improvements can now produce images of quality comparable to conventional films. However, we recommend that you use more observers and other statistical methods in this survey to obtain the desired results.

Conclusion Digital radiography is a reliable and versatile technology that extends the diagnostic and image sharing functions of dental radiography. At present, more than half of New Zealand's dentists are using digital radiography systems. They are more satisfied with radiographic systems than conventional film users. Two-thirds of movie users are interested in implementing digital radiography in the near future, but many are concerned about cost and implementation issues.

Subjective image quality comparison between two digital dental radiography systems and traditional dental films

The main difference between digital dental x-ray and film x-ray is ease of use. In digital radiography, flat electronic pads or digital dental X-ray sensors are used instead of films. The sensor receives X-rays in the same way as film, but the digital dental X-ray sensor does not develop the film in the darkroom, but sends the image directly to the computer displayed on the screen. In addition to the speed and convenience of the process, one of the main advantages of digital dental x-rays is that computers can compare images digitally with previous images. This process allows the computer to subtract all the same content from both images and leave only different content. This process, called subtraction radiography, emphasizes minimal changes, so the dentist can intervene at an early stage.
