Lumbar and lumbosacral discopathy arouses pain in the
loins and the lower back radiating to the lower extremities,
more often right than left. This can be explained by a greater
stress on the right side of the body when the doctor works
with a sitting patient. The dentist makes constant monotonous
movements, which stress the wrist and elbow joints.
Also of consequence are mechanical vibrations which are
produced by some dental equipment like ultrasonic scalers
and handpieces and are transmitted to hands and arms. In
addition, the extensive use of handtools in dentistry work can
cause a chronic extrinsic compression of the nerves in the
hand, and therefore may cause an entrapment of digital
nerves [70]. Whatever the cause of the symptoms, neurological
disturbances are potentially serious in an occupation in
which precise hand movements are necessary
