Q

Upon 1st exposure to Herpes Simplex Virus, what are the 3 possible outcomes

A
  1. Immune system completely eliminates the virus
    * Antibodies protect throughout life
  2. Inadequate immune response
    * eliminates most of the virus
    * resides in trigeminal ganglion throughout life (latent infection)
    * experiences episodes when reactivated (Prodrome)
  3. Completely inadequate immune response
    * develops primary herpetic gingivostomatitis

Q

HSV Management Plan

A

Herpes Labialis:
* topical analgesic during prodrome, not helpful after vesicles form
* Pencyclovir ointment
* Topical Acyclovir
* Docanosol-prevents virus replication, reduces healing time by 0.7 day

Herpes Stomatitis:
* Topical Analgesic
* Acyclovir Gel-can be toxic if swallow
* after prodrome-no meds

Prophylaxis:
* Only for MOST SEVERE CASES
* Valcyclovir 500 mg 2x/day

21
Q

Amalgam Tattoo

A

Flat bluish-black or gray
* Gingiva, Alveolar mucosa, buccal mucosa
* confirm w/radiograph

Pencil graphite-on hard palate

if it mimics mucosal melanoma, and no foreign body on radiograph–> BiOPSY

22
Q

Reticular Lichen Planus

A

White Striations

usually Asymptomatic
* If symptoms: tx, if no improvement=biopsy

f/u once a year

Locations:
* Buccal mucosa
* ventral & dorsal surface of tongue
* labial mucosa
* gingiva

23
Q

Lichen Planus Treatment

A

Steroids:
* Dexamethasone elixir 0.5mg/5mL x4 for up to 2 weeks
* Clobetasol gel
* Prednisone

Palliative Tx:
* Maalox
* Bendaryl
* Viscous Lidocaine

Anti-inflammatory agents:
* might be needed

Rehydration

Immunosuppresants:
* Calcineurin inhibitors

24
Q

How can you manage acute ulcers?

A

No Biopsy
* Adjust denture base-> f/u 2 weeks
* repeat to remove injury
* If still present=Biopsy

25
What is an ulcer?
Loss of epithelial * CT Exposed Craters fill in w/granulation tissue
26
Why is there a red halo around oral ulcers?
Granulation tissue
27
Clinical Features of oral ulcers?
yellow necrotic center w/red halo
28
Graphite Tattoo
Not visible on radiographs * past hx of trauma
29
What are the variants of pyogenic granuloma?
Granuloma Gravidarum * pregnant female * Pyogenic granuloma of pregnancy Epulis Granulomatosum * found in the socket of recently extracted teeth
30
How do we treat pyogenic Granuloma?
Surgical Excision (down to periosteum) Sometimes spontaneous regression occurs
31
Traumatic Ulcer
Acute onset Location: * Lateral border of tongue * Labial Mucosa
32
Traumatic Ulcer: Management
Remove source of trauma * Adjust or reline denture Allow ulcer to heal on its own * if painful=topical analgesic 2-3 weeks to heal then reassess
33
What are the prescription treatments for traumatic ulcers?
Topical anesthetic applied w/cotton tip to affected area Lidocaine Hydrochloride Oral Topical Solution
34
What is the key to understanding traumatic ulcer?
Establish traumatic etiology * never use anti-inflammatory on traumatic ulcer REMEMBER: inflammatory response is needed to heal & repair the damage
35
Salivary Duct Cyst
True Developmental Cyst * lined by epithelium Develops Secondary to Ductal obstruction * most common w/Parotid Gland (Major gland) * Minor glands--> floor of mouth, buccal mucosa, lips Clinical: * Soft, fluctuant swelling w/bluish HUE Ductal Ectasia: * Cystic like dilation due to blockage & Increased intraluminal pressure * not a true cyst
36
Peripheral Giant Cell Granuloma
37
Oral Hairy Leukoplakia
Epstein Barr virus while immunocompromised LATERAL TONGUE Etiology * HIV Infection * Hematologic neoplasms * Immunocompromised *Prolong corticosteroids Tx: * underlying cause of immunosuppression
