Periodontal Prognosis Flashcards
What is a prognosis?
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
When is a prognosis established?
After the diagnosis is made and before the treatment plan is established
What are the values of prognosis to practitioners?
Determine which treatment modalities will be most effective
Develop restorative recommendations and treatment plans
What is the value of prognosis to the patient?
Develop an understanding of present condition to facilitate informed consent
What are the type of prognosis?
Overall
Individual tooth
Diagnostic
Therapeutic
Prosthetic/restorative
Is the determination of prognosis static?
No, prognoses can change over time as treatment is rendered and response to treatment is determined
How does patient age affect prognosis?
Prognosis is generally better for older than younger patients
T or F: Prognosis can be related to the height of remaining bone
True
Why is pocket depth less important than level of attachment?
Because it is not necessarily related to bone loss
What is critical to the success of periodontal therapy and prognosis?
Effective removal of plaque on a daily basis by the patient
How is periodontitis affected by systemic disease?
Prevalence and severity of periodontitis is significantly higher in patients with type I and type II diabetes
What variable is important in diabetic patients regarding prognosis?
Level of diabetes control
How do certain conditions affect prognosis?
Conditions that limit the patient’s performance of oral hygiene procedures adversely affect prognosis
What role do genetics play in periodontal disease?
Genetic factors may play an important role in determining the nature of the host response
What has increased production of IL-1β been associated with?
An increased risk for severe chronic periodontitis
Name a local prognostic factor related to restorations.
Subgingival restorations
Name a local prognostic factor related to tooth stability.
Tooth mobility
What are some anatomical factors that affect prognosis?
Short, tapered roots; root concavities; root proximity; furcation involvement
What are some local factors that affect prognosis?
Abutment selection
Caries
Root resorption
What does risk assessment identify?
Factors that predispose a patient to developing periodontal disease
What are some prognostic factors associated with tooth loss:
Initial probing depth
Initial furcation involvement
Initial percent bone loss
Parafunctional habits without a nightguard
Tooth malposition
Mobility
Smoking
Oral hygiene
Can risk and prognostic factors be the same?
Yes, in some cases
What are the prognostic categories?
Good
Fair
Poor
Hopeless
What indicates a good prognosis in terms of periodontal support?
Adequate periodontal support (measured clinically and radiographically)
