Q. What is Digital periapical radiography?

Digital radiographs can be subjected to image processing with which the images can be altered to achieve task specific image characteristics. For example, density and contrast can be lowered for evaluations of the marginal bone and increased for evaluations of the implant components.

The possibilities of pseudo-coloring, that is, to assign different colors to different gray-level values, have been suggested to be of value in evaluating the bone surrounding the implant. So has the possibility to graphically display the variations in gray-level values over a distance, e.g. one that covers the implant-bone interface.
