Ulceration Flashcards
What is ulceration
- localised deffect of surface mucosa
- results in area of exposed connecitve tissue
What is the different between ulcer and erosion
erosion is more superficial
What are the main causes of ulceration
- infective
- traumatic
- idiopathic
- associated with systemic disease
- associated with dermatological diseases
- neoplastic
What viruses can be linked to ulceration
Most commonly herpes & coxsackie
What herpes viruses can cause oral ulceration
Herpes simplex
Ebstein-barr virus
Varicella zoster virus
When herpes reactivates and causes oral ulceration, what is this referred to as
- recurrent herpetic lesions
What viruses can cause the recurrent herpetic lesions
HSV1, HSV2, Zoster (shingles)
How does the recurrent herpetic lesions present
- ulceration is limited to one nerve group/branch on one side
- usually in hard palate
How can you differentiate the viral cause in recurrent herpetic lesions
- pain suggests shingles –> tend to experience discomfort before vescicles burst
What should we use to treat recurrent herpetic lesions
*aciclovir (systemic)
give prophylactially if severe issue
What is the aciclovir prescription for HSV
- for immunocompromised & severe infections
- 200mg, 5 times daily, 5 day regiment
What is the aciclovir prescription for herpes zoster - shingles
800mg
5 times daily
5 day regimen
What disease does coxsackie virus cause
hand foot and mouth disease
common childhood illness
What bacterial conditions result in ulceration
NUP/NUG
P.intermedia, fusobacterium and more associated
What is the most common traumatic cause for ulcers
mechanical e.g sharp cusp
What criteria should be fulfilled to be certain an ulcer is caused by trauma
- identify cause of trauma
- does the cause fit the size, shape and site of the ulcer
- on removal of the cause, there should be signs of healing within 10 days
When is a biopsy indicated for traumatic ulcer
no healing seen within 10 days
What are the types of trauma other than mechanical that could result in ulceration
- chemical
- acute thermal trauma - common in palate
- radiotherapy
Should traumatic ulcers be recurrent
should be single episode
unless source not removed
What is recurrent apthous stomatitis
- particular type of ulceration which is recurrent and generated by an immunological process in the epithelium and connective tissue
What are the 3 types of ulcers
- minor apthous
- major apthous
- herpetiform
diagnose based off worst ulcer
What size are minor apthous ulcers
<10mm
How long do minor apthous ulcers usually last
2 wks
usually heal with no scarring
