X-ray Tube
X-ray Film
Apical foremen is located up
towards the crown.
* Depending on the angle of penetration of the X-ray beam, the apex may not appear
correctly, and the position of the apical foramen may appear to be located differently
than it actually is.
Root ZX mini Meter Reading and Radiography
Sometimes the Root ZX mini meter reading and the X-ray image will not correspond. This does not
mean that the Root ZX mini is not working properly or that the X-ray exposure is a failure.
* Occasionally, the actual apical foramen does not correspond exactly. The actual apical foramen
may be located up towards the crown. In these cases, the X-ray image will seem to indicate that
the file has not reached the apex.
