Q

T/F: You do not need radiographs to make an accurate prognosis using the Becker classification.

A

False. You ABSOLUTELY need radiographs. A huge component of this system involves evaluating bone levels!

Q

T/F: radiographs are not necessary for McGuire and Nunn classification.

A

15
Q

If two patients of different ages have the same level of remaining attachment and alveolar bone, which has the better prognosis?

A

The older patient.
Younger patient suffers from aggressive disease
shorter time frame in which destruction has occurred in the younger patient

16
Q

What are the two main parameters for determining disease severity?

A

CAL

alveolar bone loss - how much of the root is still invested in bone

17
Q

Which is more important: CAL or deep periodontal pockets?

A

CAL. A deep DP does not necessarily indicate destruction of structures. Better prognosis for a patient with deep pockets and little CAL than one with shallow pockets and marked CAL.

18
Q

What do you do in a situation in which bone loss has occurred on one surface of a tooth? How do you go about developing the prognosis?

A

You should take into consideration the bone height on the less involved surfaces as well to make your prognosis.

19
Q

T/F: the prognosis is independent of the patient’s attitude, desire to retain natural teeth and willingness to maintain good oral hygiene.

A

FALSE. The prognosis is completely dependent upon those things.

20
Q

A smoker is diagnoses with slight to moderate chronic periodontitis. Immediately, he stops smoking. How might this effect his prognosis?

A

Prognosis may go from fair-poor to good.

If he was diagnosed with severe chronic perio and stopped smoking, his prognosis could be “fair”

21
Q

On which teeth are root cavities very pronounced?

A

the maxillary first premolars and mesiobuccal root of maxillary first molar

22
Q

What are the principal causes for tooth mobility?

A

loss of alveolar bone
changes (inflammation) of PDL attachment
trauma from occlusion

23
Q

What is the typical prognosis for aggressive periodontitis?

A

poor

24
Q

What is the typical prognosis for someone with periodontitis as a result of systemic disease?

A

fair to poor

25
Q

What is a typical prognosis for a patient with NUG? What about a patient with recurrent NUG?

A

Good.

fair for a recurrent patient

26
Q

T/F: the tissue damage seen in NUG is easily reversible.

A

False. Typically, the tissue damage is NOT reversible

27
Q

What is a prognosis?

A

a prediction of the course, duration and outcome of a disease based on the pathogenesis of the disease and the presence of risk factors for the disease.

28
Q

What is a typical prognosis for a diabetic that is well controlled?

A

good

29
Q

What is the most important local factor in periodontal diseases?

A

the microbial challenge by bacterial plaque and calculus

30
Q

What is the prognosis for short, tapered roots and large crowns?

A

poor

31
Q

Where are the root concavities particularly pronounced?

A

the roots of the maxillary first premolar and the mesiobuccal root of the maxillary first molar

32
Q

What is the “normal” prognosis for an individual with chronic periodontitis if the inflammation can be controlled

A

good

33
Q

What type(s) of bacterial strain(s) would you expect to see in aggressive periodontitis?

A

A. a.

some P. gingivalis

34
Q

Periodontitis as a manifestation of systemic diseases can be divided into two categories. What are those categories?

A

those associated with hematological disorders such as leukemia and acquired neutropenias

those associated with genetic disorders such as familial and cyclic neutropenia, Down Syndrome, Papillon-Lefevre syndrome, and hypophosphatasia

35
Q

What are some of the symptoms associated with hypophosphatasia?

A

decreased levels of circulating alkaline phosphatase, severe alveolar bone loss, premature loss of deciduous and permanent teeth and a connective tissue disorder

36
Q

T/F: NUP is typically seen in systemically healthy individuals

A

False. Typically, NUP is only seen in immunocompromised patients
