Bacteria
Virus
Fungus
Genetics
Systemics
Trauma

2

Infective ____ and _____ are gingival lesions of specific bacterial origin that may or may not be accompanied by lesions elsewhere on the body.

gingivitis and stomatitis

3

Which bacteria are commonly involved with infective gingivitis and stomatitis?

streptococci
mycobacterium chelonae

4

What are the clinical manifestations of gingival lesions associated with bacterial origin?

fiery red painful ulcerations
asymptomatic chancres
mucous patches
atypical, non-ulcerated, highly inflamed gingivitis

5

How are lesions of bacterial origin diagnosed?

biopsy
microbiologic examination

6

What are two lesions of viral origin?

Herpes Simplex Virus Type 1 or 2
Varicella-zoster Virus
(Type 1 usually causes oral manifestations)

7

What are the symptoms of Primary Herpetic Gingivostomatitis?

painful, severe gingivitis with redness
ulcerations with exudate
edema

8

How does Primary Herpetic Gingivostomatitis manifest?

1. Incubation lasts one week
2. Vesicles form
3. Vesicles rupture
4. Vesicles coalesce and leave fibrin-coated ulcers
5. Healing within 10-14 days

9

Herpes virus can stay latent in the _____ ganglion for years.

Trigeminal

10

Primary Herpetic Gingivostomatitis is initially located _____. Recurrent HS is more ______.

Everywhere (when primary)
localized (when recurrent)

11

Recurrent Herpetic infections such as _____ _____ effect the vermillion border and/or the skin adjacent to it.

herpes labialis

12

What percentage of individuals have herpes labialis primary infection?

20-40%

13

What factors will increase liklihood of recurrence of herpetic lesions?

trauma
uv light
fever
menstruation

14

What is herpes zoster?

varicella (chicken pox) virus
oral manifestation = small UNILATERAL ulcers on the tongue, palate, and gingiva

15

Where does herpes zoster virus go latent?

the dorsal root ganglion of the 2nd and 3rd branches of the trigeminal ganglion

16

Candidosis, Linear Gingival Erythema, and Histoplasmosis are all gingival lesions of _______ origin.

Fungal

17

True or False: There is oral carriage of C.albicans in 3-48% of healthy adults.

True

18

C.albicans is associated with _____ lesions and is frequently isolated from the ______ flora of patients with severe periodontitis.

fungal lesions
subgingival flora

19

Candidosis can be of which two forms?

Erythematous Candidosis
Pseudomembranous Candidosis
*diagnose with culture and microscopic examination of smears*

20

What is the common treatment for fungal lesions?

chlorhexidine rinse or antifungal pill

21

What is the manifestation of linear gingival erythema?

distinct linear erythematous band that is limited to the FREE GINGIVA; lack of bleeding; positive culture test for C.albicans

22

Linear Gingival Erythema is not always associated with ____ but very often it is.

HIV

23

______ is a rare granulomatous, fungal disease that is either of the Acute/Chronic Pulmonary or the Disseminated Form.

Histoplasmosis

24

Histoplasmosis first appears as nodular or papillary lesions but later becomes the _____ type with pain.

ulcerative

25

What is Hereditary Gingival Fibromatosis?

diffuse gingival enlargement that is characterized by thick tissue; it appears as a disease entity or part of a syndrome such as mental retardation; common problems include interference with eruption and "biting/chewing on enlarged gingiva"

26

What is the possible mechanism behind Hereditary Gingival Fibromatosis?

TGF-beta1 favors the accumulation of ECM
****May be a defect located on chromosome 2: "Son of Sevenless-1" gene****

27

What are the two types of allergic reactions common in the oral cavity and by which cells are they mediated?

Type1: mediated by IgE
TypeIV: mediated by T-cells

28

Allergies to dental restorative material are which type of allergy?

type IV - contact allergy (mercury, nickel, gold, etc)

29

Of the two allergy types seen in the oral cavity, which is immediate and which is delayed?

Immediate: Type I
Delayed: Type IV

chemical
physical
thermal

31

chemical

32

Poor brushing and flossing techniques, frictional keratosis, and gingival laceration would be ______ traumatic lesions.

physical

33

Which traumatic lesion type is most commonly seen on the palatal and labial mucosa and could present as painful, erythematous, or vesicular?

Thermal Traumatic Injury (burns from hot beverages)

34

What are foreign body reactions?

epithelial ulceration that allows entry of foreign material into connective tissue of the gingiva; detected via x-rays or discoloration (amalgam tattoos, toothpicks)
