What is the major difference between gingivitis and periodontitis?
Gingivitis is confined to the gingival tissues and is reversible tissue damage while periodontitis is irreversible tissue damage and infection on all parts of the periodontium
What are the 3 basic states of the periodontium
Health
Gingivitis
Periodontitis
__________ is NOT a reliable indicator of the presence or severity of chronic periodontitis
Clinical appearance
Gingivitis is seen clinically within _______ days following the accumulation of bacterial plaque
4 to 14
Gingivitis may last for years without ________
progressing to periodontitis
Periodontitis is characterized by
Apical migration of the epithelial attachment
Loss of connective tissue attachment (destruction of periodontal ligament)
Loss of alveolar bone
Tissue damage is permanent
With alveolar bone in periodontitis the bone is ________ to the CEJ
More than 1.5mm apical
The most common pattern of bone loss in periodontitis
Horizontal
What is the PATHWAY IN HORIZONTAL BONE LOSS
INTO THE GINGIVAL CONNECTIVE TISSUE INTO THE ALVEOLAR BONE
INTO THE PERIODONTAL LIGAMENT
What is the PATHWAY IN VERTICAL BONE LOSS
INTO THE GINGIVAL CONNECTIVE TISSUE DIRECTLY INTO THE PERIODONTAL LIGAMENT INTO THE ALVEOLAR BONE
CLASSIFICATION OF BONE DEFECTS IN PERIODONTITIS are CLASSIFIED ACCORDING TO NUMBER OF
–REMAINING BONY WALLS
What kind of bony defect is this?
One wall intrabony defect
What kind of bony defect is this?
two wall intrabony defect
What kind of bony defect is this?
three wall intrabony defect
What is an osseous crater
A dip in the contour of interproximal bone between the facial and lingual plates
Describe an inactive disease site
disease site that is stable with the junctional epithelium remaining at the same level for a period of time
Describe an active disease site
disease site that shows continued apical migration of the junctional epithelium over time
Most periodontal pockets show varying degrees of attachment loss on different
surfaces of the same tooth
What are the two types of pockets
gingival pocket
periodontal pocket
A gingival pocket also knows as a ________ is a DEEPENING OF THE SULCUS AS A RESULT OF INFLAMMATION DUE TO:
PSEUDOPOCKET
DETACHMENT OF THE CORONAL PORTION OF THE EPITHELIAL ATTACHMENT (WITH NO APICAL MIGRATION OF THE EPITHELIAL ATTACHMENT
SWELLING OF THE GINGIVAL TISSUE DUE TO EDEMA
A PERIODONTAL POCKET is A PATHOLOGICAL DEEPENING OF THE GINGIVAL SULCUS DUE TO:
–APICAL MIGRATION OF THE EPITHELIAL ATTACHMENT
–DESTRUCTION OF PERIODONTAL LIGAMENT FIBERS
–DESTRUCTION OF ALVEOLAR BONE
What are the two types of periodontal pockets
suprabony pocket
infrabony pocket
Describe a suprabony pocket
–BASE OF THE POCKET IS CORONAL TO THE ALVEOLAR CREST
Describe an infrabony pocket and what kind of bone loss is associated with it
BASE OF THE POCKET IS APICAL TO THE ALVEOLAR CREST
An infrabony pocket can be characterized by ______ bone loss
vertical
Describe acute gingivitis
short –duration; resolves upon professional and good self-care
Describe chronic gingivitis
may exist for years without ever progressing to periodontitis; resolves upon professional and good self-care
What is the color of gingiva in acute gingivitis
–increased blood flow causes tissue to appear bright red
What is the color of gingiva in chronic periodontitis
appears bluish red or purplish red
_______ enlarges marginal and interproximal gingival tissue
Increased tissue fluid
Cratered papillae is a feature seen in what gingival disease
acute periodontitis
_______ is seen even BEFORE clinical changes can be seen and is an important indicator of ________
Bleeding on probing
inflammation
What are the three extent and distribution of gingival inflammation
papillary
marginal
diffuse
Where is marginal gingival inflammation found
Along the interdental papilla and the gingival margin
Where is diffuse gingival inflammation found
Interdental papilla, gingival margin and attached gingiva extending to the mucogingival junction
