Chapter 6 Flashcards
(23 cards)
Complex microbial infection that triggers host-mediated inflammatory response within periodontium
Periodontitis
What is the leading cause of adult tooth loss?
Periodontitis
How does periodontitis begin?
Biofilm-induced gingivitis
What is the most frequent pattern of bone loss?
Horizontal
What are some signs and symptoms of periodontitis?
-Plaque/calculus
-Erythema/edema
-Bleeding
-Suppuration
-Perio pockets >3
-CAL/tooth mobility
What are some alterations of periodontitis?
-Reddish/purplish, pale pink tissue
-Rolled gingival margin
-Blunted or flattened papilla
-Bone loss
-Fibrotic tissue
Measurement of amount of destruction affecting tooth-supporting structures destroyed around tooth
Clinical attachment loss CAL
What is CAL characterized by?
Apical migration of junctional epithelium
Destruction of gingival and PDL fibers
Loss of alveolar bone support around tooth
One site or several sites on tooth
Sites on several teeth
<30% of teeth affected
Localized inflammation
May affect entire quadrant
Entire dentition
>30% teeth affected
Generalized inflammation
What are some contributing factors of periodontitis?
o Smoking
o Diabetes or HIV
o Genetic factors
o Tooth crowding or overhanging restorative margin
What are some symptoms of periodontitis?
-Painless
-Bleeding
-Space between teeth
-Teeth mobile
-Food impaction
-Temp sensitivity
Untreated periodontitis progresses randomly and in episodic bursts of activity
Random burst model
Periodontitis progresses in relatively short bursts, followed by periods of extended remission
Asynchronous burst hypothesis
What are the therapeutic endpoints of periodontal disease?
o Eliminate microbial factors
o Preserve current state of teeth and periodontium
o Prevent disease progression and reoccurrence
o Reinforce behavioral modifications
When should a plan for maintenance be set for periodontitis?
4-6 weeks after treatment
Seen in patients previously treated and monitored over time who exhibits continual attachment loss despite:
Appropriate periodontal therapy
Satisfactory self-care
Following program of maintenance
Refractory form of periodontitis
Return of destructive periodontitis that has been previously arrested by therapy
Recurrent form of periodontitis
Study of pathologic manifestations of periodontitis
Pathophysiology
What are the three forms of periodontitis?
Necrotizing periodontitis
Periodontitis as manifestation of systemic diseases
Periodontitis
What are periodontitis stagings defined by?
Disease severity
Complexity of management
Compares rate of attachment loss and/or bone loss over 5 years or more
Direct evidence
Percentage of bone loss at worst affected tooth
Case phenotype
Indirect evidence
