Evaluate the medical history of dental patients
before treatment begins. NAVMED Form 6600/3 will
be completed to find out whether there are any medical
problems that can affect dental treatment. Some
patients have medical conditions, such as a heart
murmur, that require antibiotic treatment 1 hour before
you can treat them. If the medical history indicates the
patient has or had a heart murmur, ask the patient if he
or she has taken any antibiotic medicine.
NOTE: If any questions on the NAVMED
6600/3 are answered "yes," it is of the utmost
importance that you discuss the patients
history with a dental officer before rendering
PATIENT AND OPERATOR
Correct operator and patient positioning helps to
accomplish the following:
Prevents operator and patient fatigue and
Permits the operator to gain a clear view of the
tooth being worked on
Allows easy access of instruments to the teeth
Position the back of the patient's chair at about a
15° angle (slightly raised above the parallel position)
to the floor (fig. 3-1).
The patient's heels should be even or slightly
higher than the head. The top of the patient's head must
be even with the end of the headrest for you to see and
reach the patient's mouth. If possible, position the
bracket tray out of the patient's direct vision. Ask the
patient if he or she is in a comfortable position.
To properly position yourself in the seated
operator position, adjust the chair so that you are
comfortable and your posture is correct. To maintain
good working posture (fig. 3-2), position your feet flat
on the floor, thighs parallel to the floor, back and head
straight, and arms at waist level. Keep your body
weight evenly distributed.
