Flashcards in Final; Prognosis Deck (54):
1

What is a prognosis

it is 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

2

When is a prognosis established

after the diagnosis is made and before the treatment plan is established

3

What are the two types of prognosis

overall
individual tooth

4

What four things compile the overall clinical factors

patient age
disease severity
plaque control
patient compliance

5

What are four systemic/environmental factors

smoking
systemic disease/condition
genetic factors
stress

6

What are four prosthetic/restorative factors

abutment selection
caries
non-vital teeth
root resorption

7

What are some factors that can affect the overall prognosis

age
current severity of disease
systemic factors
smoking
plaque/calculus/local factors
patient compliance
prosthetic possibilities

8

Why do you determine the overall prognosis before the individual tooth

if the overall prognosis of the whole moth is hopeless, then don't plan on keeping teeth regardless

9

What are some factors that can affect the individual tooth prognosis

affected by overall prognosis
mobility
probe depth
bone loss
furcation involvement
local factors

10

What are the classifications of the Becker, Berg, and Becker

good
questionable
hopeless

11

What are the classifications of McGuire and Nunn

good
fair
poor
hopeless

12

What classifies a good prognosis under the BBB classification system

<2 mobility

13

What classifies a questionable prognosis under the BBB classification system

50% bone loss
6-8mm probing depth
class 2 furcation
anatomical variables

14

What classifies a hopeless prognosis under the BBB system

more than 75% bone loss
more than 8mm probing depth
class 3 furcation
class 3 mobility
poor crown/root ratio
unfavorable root proximity
repeated periodontal abscess formation

15

*What classifies a good prognosis under the McGuire and Nunn system

adequate remaining bone support
adequate possibilites to control etiological factors
patient cooperation
no systemic environmental factors or well controlled

16

What classifies a fair prognosis under the McGuire and Nunn system

25-50% attachment loss
grade I or grade II furcation involvement
adequate maintenance possible
few systemic complications

17

What differs between BBB and M&N

M&N uses attachment loss, BBB uses bone loss

18

What classifies a poor prognosis with McGuire and Nunn

>50% attachment loss
tooth mobility
grade I and II furcation involvements
difficult to maintain areas Sandor doubtful patient cooperation
presence of systemic/environmental factors

19

What classifies a hopeless prognosis with McGuire and Nunn

>75% attachment loss
tooth mobility 2+
grade II and III furcation involvements
difficult-to-maintian areas and/or doubtful patient cooperation
root proximity

20

Why would the prognosis for a patient that is older but with the same amount of bone loss as someone younger, be better

for the older person is took however long (60 years or whatever) to get that loss, while someone younger, took less, although the younger patient may have a better restorative capacity

21

What are two parameters of disease severity

level of clinical attachment
radiographic examination shows the amount of root surface still invested in the bone

22

Which has a better prognosis; a tooth with deep pockets and little attachment loss or one with shallow pockets and severe attachment and bone loss

deep pockets and little attachment loss

23

What differs in prognosis of bone loss defects

horizontal bone loss depends on the hight of existing bone
in regards to angular bone loss, the number of remaining walls

24

This is nearer to the crown which results in a more favorable distribution of forces to the periodontium and less tooth mobility

Cres

25

This is the primary etiological factor associated with periodontal disease

bacterial plaque

26

This is critical to the success of periodontal therapy and to prognosis

effective removal of plaque on a daily basis by the patient

27

The prognosis for patients with gingival and periodontal disease is dependent on what three things

the patients attitude
desire to retain natural teeth
willingness and ability to maintain good oral hygiene

28

What are two options the dentist can do with a patient who is not compliant

refuse to accept the patient for treatment
extract the teeth with hopeless/poor prognosis and preform SRP on remaining teeth

29

This affects the severity of periodontal destructions and healing potential of the periodontal tissues

smoking

30

In smokers, prognosis of slight-moderate periodontitis is generally what

fair to poor

31

In smokers with severe periodontitis, the prognosis may be what

poor to hopeless

32

A smoker can do this to affect prognosis

cessation of smoking

33

Patients with slight to moderate periodontitis, who stop smoking can be upgraded to what prognosis

good

34

Patients with severe periodontitis who stop smoking may be upgraded to what prognosis

fair

35

Well-controlled diabetics with slight to moderate periodontitis, who comply with their recommend periodontal treatment should have what prognosis

good

36

This may be helpful to a patient and improve prognosis

electric toothbrushes

37

This is the most important local factor in periodontal disease

microbial challenge presented by bacterial plaque and calculus

38

What are three plaque retentive features that decrease prognosis

greater gingival inflammation
more marginal bone loss
poorer compliance with home care

39

Prognosis is poor for teeth with what anatomical features

short tapered roots and large crowns
disproportionate crown/root ratio
reduced root surface available for periodontal support
periodontium may be more susceptible to injury by occlusal

40

These anatomical features can interfere with SRP and can prevent regeneration of cementum and PDL

cervical enamel projections CEPs
enamel pearls
bifurcation ridges

41

These cannot attach to enamel, so you may have to remove enamel to expose cementum

gingival fibers

42

This appears on the maxillary first premolars and the mesiobuccal root of the maxillary first molar which increases the attachment area and produces a shape more resistant to torquing

root concavities

43

What are the three principal causes of tooth mobility

loss of alveolar bone
inflammatory changes in the PDL
trauma from occlusion

44

This type of tooth mobility may be correctable

tooth mobility caused by inflammation and TFO

45

This type of tooth mobility is likely to NOT be corrected

mobility due to loss of alveolar bone

46

Long term prognosis for patients with plaque induced gingival diseases modified by systemic factors depends on what two things

control of bacterial plaque and control or correction of the systemic factors

47

In drug-induced gingival enlargement this is usually necessary to correct the alterations in gingival contour

surgical intervention

48

In slight/moderate chronic periodontits, the prognosis is generally good, provided what

inflammation can be controlled

49

What type of prognosis does aggressive periodontitis have

poor

50

Periodontits as a manifestation of systemic diseases can be divided into what two categories

those associated with hematologic disorders such a leukemia and acquired neutropenia
those associated with genetic disorders such as familial and cyclic neutropenia, down syndrome, Papillion-Lefevre, and hypophosphatasia

51

Patients with periodontits has a manifestation of a systemic disease have what prognosis

fair to poor

52

The prognosis of a patient with NUG is what

good

53

The prognosis of a patient with repeated episodes of NUG is what

fair

54

The prognosis of a patient with NUP depends on what

reducing local and secondary factors but also dealing with the systemic problem (like HIV)
