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
