Prognosis Flashcards
____ is the probability that an individual will get a specific disease in a given period of time.
Risk (varies from person to person)
What are probable or putative risk factors that have been identified in cross-sectional studies but not longitudinal studies?
risk indicators (i.e. HIV/AIDS, osteoporosis, infrequent dental visits)
What are environmental or biologic factors that increase the chance that an individual will get the disease?
Risk factors (i.e. tobacco smoking, diabetes, pathogenic bacteria)
What are risk factors that are NOT typically modifiable?
Risk Determinants/Background characteristics
i.e. genetics, age, gender, socioeconomic status, stress
What are associated with risk for disease but don’t cause disease?
Risk Markers/Predictors
i.e. previous periodontal disease, BOP
What are three important things to consider when determining a prognosis?
- The time of projection (how far out – long term or short term) 2. Individual teeth or overall dentition 3. What is the end point of observation (tooth loss or periodontal stability)
how long can long term prognoses be?
5 years – after that accuracy diminishes
How do prognoses compare between single and multi-rooted teeth?
Single rooted teeth tend to have more accurate prognosis
The prognostication system proposed by Kwok and Caton in 2007 is based on what?
Probability of disease progression (likely, maybe, unlikely, hopeless)
If periodontal status of the tooth can be stabilized with comprehensive perio tx and maintenance; what prognosis does this give?
favorable prognosis
If periodontal status is influenced by local and systemic factors which may or may not be controlled; what prognosis is this?
questionable
When extraction is indicated; a __________ prognosis is given.
hopeless
If periodontal status is influenced by local and/or systemic factors which cannot be controlled; this prognosis is?
unfavorable (periodontal breakdown likely to occur regardless of efforts)
What is the #1 modifiable risk factor?
smoking (prognosis is improved 60% if stopped)
In middle-aged, white males; polymorphism of the IL-1 gene indicates what?
higher probability to develop periodontal disease
Who are more likely to get diagnosed with periodontal disease - men or women?
Men – also have greater severity
What are 6 local risk factors that play into periodontal Dx and Px?
gingival inflammation, suppuration, plaque/calculus, persistent deep pockets, remaining attachment, mobility
Smoking interferes with what sign of gingivitis/periodontitis?
inflammation/BOP
How much naturally occurring attachment loss is seen each year?
0.1mm
Name three causes for tooth mobility
loss of alveolar bone, inflammation of the PDL, occlusal trauma
What are some anatomical factors that make periodontal therapy more difficult?
Enamel pearls, bifurcation ridges, root concavities, developmental grooves, root proximity, furcation grooves
What are the prognostic factors on the tooth level?
mobility, amount of remaining attachment, probing depth, bone loss, presence/absence/severity of furcation lesions, crown-root ratio, endodontic status, caries
