6.5 TMJ examination
The TMJ examination with open or closed mouth is similar to panoramic,
the only difference is that the exposure is performed only on the involved
area (Temporal mandibular Joint). then it stops and starts on the second
articulation. The operation sequence of the examination is therefore
similar to the one described for the panoramic.
This TMJ function enables to obtain 4 different images on the same film,
by performing two rotational movements. The 4 images represent the
right and left condyle of the temporal-mandibular arch (TMJ) with closed
mouth and open mouth.
Selecting closed mouth exam only the external sectors of the film are
exposed, while selecting open mouth exam, the exposure occurs on the
inner sectors.
The position of the images couples the images corresponding to the same
condyle to help a diagnosis. The Figure 14 shows the information related
to the single sectors.

NOTE:
During TMJ the X-rays emission is not continuous since it is interrupted
during the transition phases between the different exposures, but is
necessary to keep pressed the X-ray button "30" for the whole rotation
time.
Do not release the X-ray button during the emission interruption if not
necessary.
The cooling phase of the tubehead occurs at the end of all 4 exposures.
In the CHILD position, exposure start is delayed by a few degrees with
respect to the ADULT position.
