What is periodontal disease and what does it include?
What are the two basic categories of periodontal disease?
What is the periodontium in health?
What is gingivitis?
What are the microscopic changes seen in gingivitis?
Characterized by what clinical changes
Where is the JE and condition?
Condition of supragingival fibers
What kind of pocket is possible?
What is a gingival pocket?
How is the gingiva enlarged during acute and chronic gingivitis?
What is periodontitis?
Where does the inflammation extend?
Development of what type of pockets?
What causes marked changes in connective tissue and junctional epithelium?
What is the clinical picture of periodontitis?
Where is the JE?
Supragingival fibers?
Alveolar bone?
Periodontal ligament?
What happens to connective tissue and gingival fibers in periodontitis?
What happens to the JE in periodontitis?
What happen to the collagen fibers apical to JE?
What facilitates the apical migration of the JE onto cementum? This prevents what? Results in what?
What happened to the ridges of the JE and sulcular epithelium in periodontitis and what occurs as a result?
What happens to the transeptal fibers in periodontitis?
what causes a periodontal pocket?
The two types of perio pockets difference lies in what?
What is a suprabony pocket?
What is a infrabony pocket?
What leads to destructions of alveolar bone? What is the ultimate cause?
Name some bone resorbing factors
Causes of bone destruction
Alveolar bone height in health
Alveolar bone height in periodontitis
Bone loss can present in patterns. Varies and depends on what?
The pathway of inflammation will determine what?
What is the pathway of inflammation for horizontal and vertical bone loss?
Bone destruction typically does not occur within ____of plaque mass at the base of the pocket
What determines the type of bone loss?
A wide crestal septum is what width, what type of teeth have a WCS and what type of bone loss will typically happen here?
A narrow crestal septum is what width, what type of teeth have a NCS and what type of bone loss will typically happen here?
What are the two type of bone loss?
What is the most common type of bone loss?
Horizontal
Describe horizontal bone loss
Horizontal bone loss produces what type of pockets? The deepest part of the pocket is where? What kind of defect is it?
Vertical bone loss occurs in what direction?
Describe vertical bone loss
What rates does vertical bone loss occur?
VBL is more rapid where?
What kind of bony defect is it?
Results from inflammation traveling from
Most occur where?
Can also occur?
Osseous walls in health and in perio
What are the different infrabony defects? How are they classified?
Three wall bony defect
Two wall bony defect
One wall bony defect
What is a hemiseptum?
What is an interdental crater?
Anatomic features affecting bone loss patterns
What is defined as attachment loss?
Attachment loss spreads and has what pattern?
Describe the episodic nature of periodontitis
What is a disease site? What are the different types of disease sites?
Most accurate way to measure attachment loss
What are the different severities of attachment loss?
How do we document periodontal condition?
