“…A digital image seen on the screen as a collection of brighter and darker areas is composed of a set of cells that are ordered in rows and columns. Individual cells are called “picture elements,” which has been shortened to “pixels” 3,4. Each of these pixels has a number or digit assigned to it, based upon the amount of exposure the sensor received for the corresponding area.…”

“…Digital subtraction radiography software subtracts the value of the corresponding pixels of two images obtained within an interval of a few weeks or a few months, and it uses the outcome to calculate a new image 4,5. When the gray levels of the corresponding pixels are the same, the output pixel is zero.…”

Image post-processing of dental digital radiographs, a function which used commonly in dental practice is presented in this article. Digital radiography has been available in dentistry for more than 25 years and its use by dental practitioners is steadily increasing. Digital acquisition of radiographs enables computer-based image post-processing to enhance image quality and increase the accuracy of interpretation. Image post-processing applications can easily be practiced in dental office by a computer and image processing programs. In this article, image post-processing operations such as image restoration, image enhancement, image analysis, image synthesis, and image compression, and their diagnostic efficacy is described. In addition this article provides general dental practitioners with a broad overview of the benefits of the different image post-processing operations to help them understand the role of that the technology can play in their practices.
