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

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
Q

What is an ulcer?

A

Loss of epithelial
* CT Exposed

Craters fill in w/granulation tissue

26
Q

Why is there a red halo around oral ulcers?

A

Granulation tissue

27
Q

Clinical Features of oral ulcers?

A

yellow necrotic center
w/red halo

28
Q

* Pyogenic granuloma of pregnancy

Epulis Granulomatosum
* found in the socket of recently extracted teeth

30
Q

How do we treat pyogenic Granuloma?

Surgical Excision (down to periosteum)

Sometimes spontaneous regression occurs

31
Q

A

Acute onset

Location:
* Lateral border of tongue
* Labial Mucosa

32
Q

Traumatic Ulcer: Management

33
Q

What are the prescription treatments for traumatic ulcers?

A

Topical anesthetic applied w/cotton tip to affected area

Q

What is the key to understanding traumatic ulcer?

A

Establish traumatic etiology
* never use anti-inflammatory on traumatic ulcer

REMEMBER: inflammatory response is needed to heal & repair the damage
