Q

What tactile sensations do you feel in normal conditions?

A

None. The probs moves smoothing from junctional epithelium to gingival margin.

17
Q

What tactile sensations do you feel with spicules?

A

Probe transmits gritty sensation to fingers as passes over fine granular deposits.

18
Q

What tactile sensation do you feel with a ledge of subgingival calculus?

A

As the probe moves over the tooth surface it moves out and around raised bump and then returns to the tooth surface

19
Q

Tactile sensation for restoration with overhang margin

A

Probs path is blocked by overhang and must move away from tooth surface and over restoration

20
Q

Tactile sensation for restoration with deficient margin

A

Probs passes over restoration and dips into trace the surface of restorations

21
Q

Tactile sensation of carious lesions

A

Probe dips and comes out again as it travel along tooth surface.
Soft lesions it can get stuck or feel sticky.

22
Q

Cons for lighting as a deposit detection method

A

Access and skill dependent
Time
Subjective
Poor lighting

23
Q

Pros for using lighting and a deposit detection method

A

Immediate
Can show to patient using camera or mirror
Indicator for at home monitoring
Quick
Cost free

24
Q

Cons for using tissue changes as deposit detection

A

Poor lighting
Access and skill dependent
Time
Share subjective to each clinician
Knowing what is normal for individual patients

25
Q

Pros for using tissue changes at deposit detection

A

Immediate
Show to patient
Indicator for at home monitoring
Cost free
Good monitoring tool

26
Q

Cons for using compressed air as tissue detection

A

Lighting
Access and skill dependent
Time
Only supra gingival

27
Q

Pros for using compressed air for deposit detection

A

Immediate
Show to patients
Cost free

28
Q

What is the name of the grasp you should take when holding an instruments?

A

Modified pen grasp with no blanching of fingers

29
Q

What tooth surfaces would you slant the periodontal probe at when probing?

A

Mesial and distal

30
Q

What tooth surfaces would you keep the periodontal probe straight when probing?

A

Buccal and lingual mid surfaces
