Periodontal Disease Development Flashcards
The stages of Gingivitis and Periodontitis are divided into?
Initial Lesion
Early Lesion
Established Lesion
Advanced Lesion
Initial Lesion
Microscopic
Occurs 2-4 days of irritation from bacteria accumulation
Increased gingival sulcus fluid
No clinical evidence of change
Early Lesion
Biofilm olderand thicker
7-14 days
Clinical Appearance: Signs of gingivitis w/ slight gingival enlargement.
Gingivitis is reversible when biofilm is controlled
Depends on PT.
Established Lesion
Formation of pocket (4mm)
Evidence of inflammation w/ marginal redness, BOP and spongy marginal gingival
Advanced Lesion
Biofilm microorganisms produce irritants
Alveolar bone destruction
Diseased cementum contains a thin superficial layer f endotoxins from bacterial breakdown.(what causes bone level stretch)
A diseased sulcus?
A pocket
A pocket has an _________(the tooth surface) and an _______(the sulcular epithelium) of the free gingiva.
Inner wall
outer wall
A pocket formed by gingival enlargement without a apical migration of the junctional epithelium?
A Gingival Pocket
A pocket formed as a result of disease or degeneration that caused the JE to migrate apically along the cementum?
A Periodontal Pocket
Medications that cause Gingival Enlargement?
Phenytoin- used for seizures
Cyclosporine- immunosuppressant used for organ transplant to prevent rejection.
Nifedipine- used for angina and ventricular arrhythmais
What measures Furcation?
Nabors Probe
What is the primary etiologic factor in development of gingival and periodontal disease?
Biofilm
White fibers of the connective tissue? (Term)
Collagen
Enzyme that catalyzes the degradation (Hydrolysis) of collagen?
Collagenase
An accumulation of excessive fluid in cells, tissues, or a serous cavity?
Edema
Not readily responsive to treatment?
Refractory
A poison, protein produced by certain animals, higher plants, and pathogenic bacteria?
Toxin
Risk factors for periodontal disease?
Effect of certain drugs
Tobacco
Diabetes
An exposure that increases probability that disease will occur?
Risk Factor
A factor in the immediate environment of the oral cavity or specifically in the environment of the teeth or periodontium?
Local Factor
Etiologic, predisposing, contributing, or risk factors may be either?
local or systemic
Functions of Attached Gingiva?
Give support to marginal gingival
Withstand stresses of mastication and toothbrushing
Provide attachment for moveable alveolar mucosa.
