Prognosis

Question 1

Prognosis

Answer 1

Prediction of the course duration and outcome of disease based on pathogenesis of the disease and the presence of risk factors for that disease

Question 2

Prognosis occurs

Answer 2

After diagnosis before treatment plan

Question 3

Overall prognosis

Answer 3

Occurs before individual tooth prognosis

If overall is poor each tooth doesn’t get a prognosis

Question 4

Patient Age

Answer 4

Prognosis is usually better in the older

• shorter time frame destruction has occurred
• Aggressive disease due to smoking or disease
• Observed destruction indicates the inflammation overcomes repair for this patient. Younger expected to have greater repair

Question 5

Deep pockets and little attachment

Answer 5

Better prognosis than shallow pockets and severe attachment and bone loss

Question 6

Horizontal bone loss

Answer 6

Prognosis depends on the height of the existing bone

Question 7

Vertical bone loss

Answer 7

Prognosis depends on number of remaining walls

-when 2 surfaces have unequal bone loss: surface with greater bone loss will determine prognosis

Question 8

_____is the primary etioloigic factor associated with periodontal disease

Answer 8

Bacterial plaque

-therefore removal of plaque on a daily basis by the patient is critical to the success of periodontal therapy and to the prognosis

Question 9

Patient Compliance

Answer 9

Prognosis depends on

• Attitude, desire to retain natural teeth
• Willingness and ability to maintain good oral hygiene

Question 10

____Always downgrades the prognosis

Answer 10

Smoking

Question 11

Smoking + Severe periodontitis

Answer 11

Poor to hopeless

Question 12

Slight to moderate +Smoking

Answer 12

Fair to poor

Question 13

Smoker=

Answer 13

100 cigs/ lifetime +current

Question 14

Factors affecting individual Prognosis

Answer 14

Tooth mobility
Probe Depth
Bone Loss
Furcation involvement

Question 15

Which tooth mobility is correctable

Answer 15

Caused by inflammation and trauma -correctable

Loss of alveolar bone-not likely to be corrected

Question 16

poor prognosis for roots

Answer 16

With short tapered and large crowns

Root concavities

Question 17

Root concavities appear

Answer 17

Max 1st premolar

Max MB root of 1st molar

Question 18

Aggressive

Answer 18

Poor

Question 19

Chronic P slight to moderate

Answer 19

Good if inflammation can be controlled

Question 20

Perio as manifestation of systemic disease

Answer 20

Fair to poor

Question 21

NUG

Answer 21

Good prognosis

Repeated-fair

Question 22

Good Prognosis

Answer 22

25% attachment loss and or Class I furcation
Adequate remaining bone support
Cooperative patient
No systemic environmental factors (or well controlled)

Question 23

Fair Prognosis

Answer 23

20-50% attachment loss
Grade I or easily accessibly grade II furcation
Adequate systemic complications

Question 24

Poor Prognosis

Answer 24

> 50% attachment loss
Class 2 mobility
Inaccessible grade II furcation involvement, Grade III furcation
Difficult to maintain areas
Doubt cooperatin
Presence of systemic environmental factors

Question 25

Hopeless Prognosis

Answer 25

>75% attachment loss
Tooth mobility 2+
Grade II and III furcation involvement
Difficult to maintain
Doubt cooperation
Root proximity
