Prognosis Flashcards
Prognosis
Prediction of the course duration and outcome of disease based on pathogenesis of the disease and the presence of risk factors for that disease
Prognosis occurs
After diagnosis before treatment plan
Overall prognosis
Occurs before individual tooth prognosis
If overall is poor each tooth doesn’t get a prognosis
Patient Age
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
Deep pockets and little attachment
Better prognosis than shallow pockets and severe attachment and bone loss
Horizontal bone loss
Prognosis depends on the height of the existing bone
Vertical bone loss
Prognosis depends on number of remaining walls
-when 2 surfaces have unequal bone loss: surface with greater bone loss will determine prognosis
_____is the primary etioloigic factor associated with periodontal disease
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
Patient Compliance
Prognosis depends on
- Attitude, desire to retain natural teeth
- Willingness and ability to maintain good oral hygiene
____Always downgrades the prognosis
Smoking
Smoking + Severe periodontitis
Poor to hopeless
Slight to moderate +Smoking
Fair to poor
Smoker=
100 cigs/ lifetime +current
Factors affecting individual Prognosis
Tooth mobility
Probe Depth
Bone Loss
Furcation involvement
Which tooth mobility is correctable
Caused by inflammation and trauma -correctable
Loss of alveolar bone-not likely to be corrected
poor prognosis for roots
With short tapered and large crowns
Root concavities
Root concavities appear
Max 1st premolar
Max MB root of 1st molar
Aggressive
Poor
Chronic P slight to moderate
Good if inflammation can be controlled
Perio as manifestation of systemic disease
Fair to poor
NUG
Good prognosis
Repeated-fair
Good Prognosis
25% attachment loss and or Class I furcation
Adequate remaining bone support
Cooperative patient
No systemic environmental factors (or well controlled)
Fair Prognosis
20-50% attachment loss
Grade I or easily accessibly grade II furcation
Adequate systemic complications
Poor Prognosis
> 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
Hopeless Prognosis
>75% attachment loss Tooth mobility 2+ Grade II and III furcation involvement Difficult to maintain Doubt cooperation Root proximity
