Exam 2; Chronic Periodontitis Flashcards
What are clinical features of chronic periodontitis involving more of the gingiva
changes in gingival morphology BOP increased probe depth attachment loss gingival recession
What is the hallmark of chronic periodontitis
attachment loss
What are the clinical features of chronic periodontitis involving more of the whole tooth
alveolar bone loss furcation involvement increased tooth mobility drifting of teeth tooth loss
In which individuals is chronic periodontitis more prevalent
adults
Tissue destruction commensurates (corresponds) with what three things
oral hygiene and plaque levels and local/systemic diseases
This specific thing is implicated in chronic perio
specific sub gingival species
This is invariably present at the disease state
subgingival calculus
What is the rate of progression of chronic periodontitis
slow to moderate; rapid bursts of destruction can occur
These determine pathogenesis and progression
host factors
Untreated diseased sites are what
more likely to sustain further breakdown
What are some symptoms of chronic periodontitis
mostly painless loose teeth food impaction drifted teeth/spacing root sensitivity bleeding gums
How is localized chronic periodontitis categorized
≤ 30% of sites
How is generalized chronic periodontitis categorized
> 30% of all sites
How is slight chronic periodontitis categorized
1-2 mm of attachment loss
How is moderate chronic periodontitis categorized
3-4 mm of attachment loss
How is severe chronic periodontitis categorized
5 mm or more of attachment loss
What is the typical diagnosis
generalized slight with localized moderate chronic periodontitis
This is an environmental, behavioral or biologic factors, which when present increases the likelihood that an individual will develop disease
risk factor
This can modify the risk factor (smoking/diabetes)
intervention
These are two non-modifiable risk factors
age and gender
These are putative risk that have been identified in cross sectional studies but not confirmed longitudinally
risk indicators
What are three risk indicators
HIV/AIDS
osteoporosis
infrequent dental visits
This is a characteristic associated with elevated risk for disease buy may not be part of the causal chain
risk markers/predictors
What are three risk markers/predictors
furcation involvement
calculus
history of attachment loss
What was the early studies view on gingivitis and CP
all gingivitis leads to periodontitis but then later thinking that gingivitis and CP are separate
bacterial plaque induces gingivitis, but what determines if CP will develop
host response
What is todays view of gingivitis and CP
different aspects of the same disease
What is the epidemiology of periodontitis
47% of US population has periodontitis
most of it moderate perio
What group(s) of people have the highest prevalence of CP
men mexican americans adults with less than high school education adults below the poverty level current smokers
Severe periodontitis is the what most prevalent disease in the world
6th most prevalent
What three things are increasing the burden of SP
growing world population
increasing life expectancy
significant decrease in prevalence of tooth loss
This is the mobility of a tooth in occlusion and is used to aid in diagnosis of CP
fremitus
What is used to diagnose CP
probing depths gingival recession CAL (probing depth + gingival recession) BOP furcation involvement mobility bone defects
What are the bony defects in diagnosing CP
1 - wall
2 - wall
3 - wall bony defects
What are the three goals of treatment for CP
eliminate etiology
eliminate or reduce risk factors
prevent recurrence
What are the three steps of initial periodontal therpay
removal of but sub and supra gingival plaque
adequate oral hygiene
remove local and systemic risk factors
What are the three rationales for periodontal therapy
periodontal treatment of CP is effective
non-compliant patients had double the rates of tooth loss
untreated patients loss approx. 0.6 teeth/year
What are three things associated with probing depth reduction after therapy
gingival recession and
gain of clinical attachment
pocket shrinkage
This outcome of initial therapy indicated that sites with initial shallow pockets tend to lose what
CAL (gingival recession + probing depths) (possible trauma)
There is a greater risk for what if presenting multiple sites with residual probing depth ≥ 6mm after active treatment
additional attachment loss
bottom line; you cannot maintain 6mm pockets; surgery
