(GUARANTEED PASSS)
List and describe the four general positions for the patient in the dental
chair - answer Upright: completely up 90 degree angle
semi-upright: a little leaned back (vertigo)
Supine: laying fully flat on back (supports circulation)
Trendelenburg: head tipped down 10-15 degrees lower than heart.
(emergency placement)
List the objectives for the preferred working position of the clinician -
answer Neutral seating position:
1. back is maintaining cervical lordosis, thoracic kyphosis and lumbar
lordosis.
2. head flextion 15-20 or less
3. eyes directed downwards
4. shoulders relaxed and parallel with hips
5. elbows close to the body and low
6. wrist and forarm in a straight line
7. hips are slightly higher than knees
8. thighs are holding distrubuted weight
9. knees are apart (straddled)
10. feet are flat on the ground
List causes and complications of the musculoskeletal disorders - answer
cause: not being in ergonomic position for extended periods of time,
irritated muscles or on going pain or numbness
, Complications: pain, tingling, numbness, decrease of range of motion
Apply ergonomic principles in dental hygiene practice, including:
demonstrae neutral shoulder, elbow, forearm, and wrist positions. -
answer shoulders down and relaxed
elbows and forearms parallel to the ground. wrists unmoving and straight
List part of the dental mirror - answer handle: holding part
shank: rod between holding and working end
working end: the mirror
List and describe 3 types of mirror surfaces - answer Front service:
reflecting service is on the front service of the glass, easily scratched,

concave: produces a magnified image, reflecting service is on the front
service of the mirror lens, magnification distorts image
Plane: reflecting surface is on the back surface of the mirror lens, double
image may be distracting
Indirect vision - answer is the use of dental mirror to view a tooth surface
or intraoral structure that can not be seen directly. (lingual of maxillary)
indirect illumination - answer the use of the mirror surface to reflect light
onto a tooth surface in a dark area of the mouth
Transillumination - answer The technique of directing light off of the
mirror surface and through the anterior teeth trans=through
illumination=light
retraction (tongue and cheek) - answer use of the mirror head to hold the
