5 Wide applications Generally, xeroradiography has interesting applications in the management of neoplasm of laryngopharyngeal area, selleck bio mammary and joint region, as well as an aid in cephalometric analysis. POSSIBLE DISADVANTAGES OF XERORADIOGRAPHY One of the key characteristics of xeroradiography is the use of electrostatic charges in xeroradiographic process. Such charges stand the risk of being lost in confined humid oral environment in intraoral xeroradiograph.5,22,26 This is very difficult to overcome. Technical difficulties Both the amount of radiation exposure and the thickness of xeroradiographic plate are linearly proportional. An increased thickness of the plate will increase the speed, because of the greater likelihood that the x-rays passing through the photoconducting layer will interact.
27 Fragile selenium coat The amorphous selenium photoconductor is a highly electrically stable layer. However, the layer is quite easily scratched. Notwithstanding, it has been observed that the surface shows good resistance to scratching, chipping and abrasion. As a result, placement and retention in confined area like the mouth would possibly be difficult.5,19,22 Transient Image Retention Rawls and Owen19 reported that xeroradiographic process involves residual charge patterns and therefore, the imaging process should be completed as soon as possible. However, as long as the charge pattern is retained, the technique allows multiple copies to be obtained from the pattern.22,23 Slower speed Comparatively, xeroradiography has a lower speed than halide radiographs.
This can be significant when dealing with intraoral films.21,26 Technical limitations Certain technical limitations, such as low density of the selenium plate which requires increased doses of the x-rays administered make the technique not to be considered as a total substitute for halide radiograph.28 POTENTIAL ENDODONTIC APPLICATIONS Xeroradiography has several effects on the soft tissues that make the technique potentially useful in endodontics.29 First, soft tissues on xeroradiographic films have well defined outlines that may permit confident evaluation of the soft tissue height and contour. Second, xeroradiographs provide greater overall soft tissue detail making possible evaluation of its density, texture, and contents. Third, the technique reveals soft tissues calcifications which are not easily discerned in conventional radiographs.

Other workers are of the view that some unique properties such as greater latitude of exposure, high resolving power, and the property of edge enhancement may be useful in endodontics. These properties may be exploited when detailed visualization of lamina dura, bony trabeculae, fine metal instruments like files, broaches etc, root apices, periodontal ligament spaces are required.
