Interpretation of periapical lesions using RadioVisioGraphy

Journal of Endodontics, 1994
Density and gray-scale changes in radiographs are important visual features the clinician uses to evaluate changes in bone pattern. With the advent of a new direct digital radiology system, RadioVisioGraphy (RVG), the controlled adjustment of contrast is now possible.

The decompression technique utilizing tubing for the treatment of large periapical lesions has been widely used with success. However, unobtainable biopsies and patient noncompliance are among the disadvantages that are of concern. An alternative approach is presented, whereby a surgical procedure is performed involving only partial removal of tissue ...
