Oral Soft Tissues II Flashcards
T/F
The normal periodontium has little to none Sulcular/Gingival Crevicular Fluid
True
How much Gingival Crevicular Fluid (sulcular fluid) is there without gingivitis?
0.42 - 1.56 microliters
What type of Antibodies are in sulcular fluid?
IgG
What are 3 defense mechanisms of the Gingiva?
Sulcular fluid
Leukocytes
Saliva
What antibodies are found in Sulcular Fluid?
IgG
T/F
Smoking increases Sulcular Fluid
True
T/F
More than 90% of Leukocytes in the gingival sulcus are PMN’s
True
T/F
Glycoproteins and mucoids are serve as lubrication and physical protection in the saliva
True
What is the major antibody of the Saliva?
Of sulcular fluid?
IgA
IgG
What are 2 antibacterial components of Saliva?
Lysozyme
Lactoperoxidase (oxidize susceptible bacteria)
Gingival Inflammation:
How many days for Initial lesion?
Early lesion?
Established lesion?
2-4 Days
4-7 Days
14-21 Days
The initial lesion (2-4 days) sees a rise of what?
Increase in Gingival Cervicular Fluid
T/F
Gingival Bleeding is Cell rich and Collagen poor and is defined by a sulcular ulceration
True
What are 3 types of Generalized gingivitis?
GM - gingival margin
AG - atached gingiva
Papillae
T/F
Chronic inflammation of the Gingiva progresses from Papilla to Gingival Margin to Attached Gingiva
True
What can cause a local color change of the gingiva?
Systemic?
Amalgam
Heavy metals
T/F
The consistency of gingival tissue from health to chronic inflammation proceeds from Firm > Edematous > Fibrotic
True
T/F
Two types of Chronic Inflammation are Plaque associated and Mouth breathing
True
T/F
Two types of Acute Inflammation of the gingiva are Gingival Abscess and Periodontal Abscess
True
T/F
Drug-induced Enlargement of the gingiva is a type of Hyperplasia
False
*just enlargement
Where does Drug-Induced enlargement of the gingiva begin?
Interdental papilla
*extends to facial/lingual margins
3 features of Pathogenesis of Anticonvulsant gingival enlargement:
Fibroblast proliferation
Collegenase deactivation
Plaque-induced inflammation
T/F
The dose of Anticonvulsant is responsible for amount of gingival enlargement
False
*dose response doesn’t seem to matter
What is more vascular in nature, an enlargement caused by Phynytoin (anticonvulsant), or one cause by Cycolsporine/Tacrolimus (immunosuppressants)>
Cyclosporine/Tacrolimus
*Also appears to be dose related
**Expressed in 20-70% of pts taking drug - wow
