Q

T/F: Place the tip of the power instrument subgingival and work to coronal surface?

A

False. Place tip at most coronal position of the deposit and work apically.

A

oblique
overlapping
repetitive
Slow
vertical

23
Q

What part of the power instruments need to be cooled while using?

A

Piezo: only working end needs cooled.
Magneto: working end and handpiece.

24
Q

Are there any places or types of tissue that not not require power instruments?

A

Yes, Normal sulci, healthy no biofilm. They are colonized with good bacteria.

25
Q

Is the saliva ejector an effective way to control aersols?

26
Q

What part of the tips are the the most effective?

27
Q

Transverse tip orientation indication (uses)

A

* slightly below gingival margin

28
Q

What tips can be used on all surfaces in the transverse position?

A

Universal tips

29
Q

What tips are needed for right and left interproximals?

A

curved tips

30
Q

T/F: vertical tip with power instrument orientation is similar to the universal hand scaler in a toe-down position?

31

35
Q

What are some perio risk factors we look for while doing DHDx

A
  1. tobacco
  2. alcohol
  3. nutrition
    4.genetics
  4. gender (males)
  5. cultural
  6. systemic conditions (diabetes, osteoporosis)
36
Q

What are constraints and give an example?

A

interferences with the outcome of treatment being met. Ex: compliance of pt not adapting oral hygiene instruction given.
Ex: uncontrolled diabetes, something the patient is not able to change or doesn’t make an effort into changing.

37
Q

What is the function of DHDX? (purpose)

A

1.To provide evidence based care that is individualized.
2. To eliminate or control disease factors
