Prognosis Flashcards
Prognosis definition
likely outcome of an illness with or without treatment-a forecast of the probable course and final outcome of the disease
Essential elements of prognosis (2)
timing of the projection, individual tooth versus overall dentition
Timing of the projection (3 prognosis)
initial, short, long (define)
- initial prognosis-before
- short term prognosis: less than 5 yrs
- long term pronosis (>5yrs)
Prognosis comes from the latin term _____
foreknowledge
Most traditional systems are based on tooth mortality
data based on when a tooth is lost– not truly relevant since?
teeth don’t just fall out
Prognosis factors
characteristics that may predict the outcome once the disease is present but DO NOT actually cause it (i.e. accessibility of a furcation)
How we define survival
as long as it is still in the oral cavity
Success as defined with perio prognosis (3 things)
sucess is defined as stable, functional, and comfortable
If a tooth has what 3 qualities it should likely been retained?
Stable, functional, comfortable-hence it is a success
overall prognosis determined via?
communication between pt and professionals
T/F; periodontal disease progresses uniformly throughout the dentition
False; it does not
Local factors that affect individual prognosis (prognostic factors-6 things)
Deep probing depth Molars Post. proximal sites Palatal grooves/CEP/EP Overhanging restorations Food impaction sites
Worse: vertical or horizontal bone loss?
horizontal bone loss-can treat and reverse vertical bone loss better
greater prognosis, vertical or horizontal bone loss?
horizontal has a LOWER prognosis
2 levels of evaluation when considering a comprehensive approach
patient level and individual tooth level
Patient level includes (3)
biological risk, environmental risk, financial and behavioral
20yr old with 20% bone loss vs 60yr old with 20% bone loss; worse prognosis?
20yr old
Evaluation of individual teeth; how many criteria and additional factors?
4 main criteria and 2 additional factors
the 4 main criteria and 2 additional factors for the evaluation of individual teeth
PERO
- Periodontal condition and alveolar bone support
- Endodontic condition
- Restorability, remaining sound tooth structure
- Occlusal place and tooth position including… anatomical irregularities and Iatrogenic compromising factors
**WORTH KNOWING
teeth most likely to be lost due to furcation
max second molars-molars in general tho
All of these studies are based on what study type? (hint-when/how where they done)
retrospective private practice analysis-I am sure this does not matter though
