Q

Some sextants have 1 possible seating position. Some have 2. What are the reasons to learn both possible positions for some sextants?

A
  • Surgery design may not allow for certain positioning.
  • Patients arches and teeth vary in size and alignment.
  • Some tooth surfaces difficult to reach from favourite position if they are rotated.

Q

Disadvantages of palm grasp

A
  • Limited range of movement.

- Limited tactile conduction.

17
Q

Modified pen grasp finger placement

A
  • Thumb and index finger hold the handle in a curved shape with light grip for easier rotation.
  • Middle finger rests lightly on shank for tactile sensation and to guide the instrument. The side of the finger does not touch the shank.
  • The ring finger is the fulcrum. It stabalises the hand. Keep straight in a locked position.
  • Little finger serves no function or offers some support. Hold is a comfortable and relaxed manner.
18
Q

Palm grasp finger placement

A
  • All fingers hold the instrument.

- Thumb stabalises the hand in the patients mouth.

19
Q

What is a fulcrum?

A
  • The support or point of rest on which a lever turns in a moving body.
  • The fulcrum is the tooth.
  • The lever is the finger.
  • The moving body is the instrument.
20
Q

Indirect illumination

A

Using the mirror to illuminate an area.

21
Q

Transillumination

A
  • Reflection of light through teeth.
  • Can reflect light from the overhead light through lower anterior teeth to see the translucency of enamel.
  • Dental caries and calculus deposits appear opaque.
22
Q

Instrument shank should be parallel to…

A

The long axis of the tooth.

23
Q

Sickle scalers

A
  • Sickle scaler H6/H7 - Supragingival calculus from interproximal surfaces 3-3.
  • Posterior mini sickle S204 - posterior upper and lower teeth 4-8.
24
Q

Chisel/push scaler

A

Supragingival calculus from interproximal surfaces of anterior teeth (mainly lower) 3-3.

25
Q

Universal curette 13/14 (Coloumbia)

A

Removal of fine subgingival deposits from all surfaces.

26
Q

Technique for scaling

A
  • Adaptation.
  • Angulation.
  • Stabalisation.
  • Stroke activation.
  • Reposition.
27
Q

Adaptation definition

A

The manner in which an instrument is brought into contact with a tooth surface and maintained during instrumentation.

28
Q

Adaptation

A
  • Cutting edge adapted to tooth for effective removal.

- Working end is rolled around the tooth to adapt to different areas.

29
Q

Angulation definition

A

The angle formed when the working end of the instrument comes in contact with the tooth surface.

30
Q

Angulation

A
  • Rake angle - Scaling more efficient if the tip leans back from the direction of movement.
  • Rake angle is positive if the instrument tip leans back.
  • Rake angle is negative if the instrument tip leans forward.
  • Clearance angle - The angle between the non-working lateral surface of the scaler and the tooth.
  • Handles should be parallel to teeth.
31
Q

Stabalisation

A

Fulcrum

32
Q

Activation definition

A

Motion activation refers to the manner in which you move the instrument and your hand during instrumentation.

33
Q

Activation

A
  • Digital motion - Flexing fingers. Quickly fatigues fingers.
  • Wrist rock.
  • Rotating motion.
  • Vertical.
  • Oblique.
  • Horizonal.
34
Q

Reposition

A

Move to new area and repeat process.
