acute and chronic ulcerative lesions 1 Flashcards
anesthetic necrosis category
injury
anesthetic necrosis etiology
- necrosis secondary to administration of local anesthetic
- may result from ischemia or faulty technique
anesthetic necrosis demographics
patients who recently received oral local anesthetic
anesthetic necrosis clinical presentation
- well circumscribed ulcer at site of previous injection
- hard palate most common site
anesthetic necrosis diagnosis
clinical diagnosis based on history of recent local anesthetic injection
anesthetic necrosis tx
heals over time
necrotizing sialometaplasia category
injury
necrotizing sialometaplasia etiology
ischemia of salivary tissue leads to local infarction
necrotizing sialometaplasia demographics
predisposing factors:
- trauma
- dental injections
- ill-fitting dentures
- eating disorders with binge-puringing
- upper respiratory tract infection
remember injury category
necrotizing sialometaplasia clinical presentation
- most cases on hard palate
- nonulcerated, painful swelling initially
- within 2-3 weeks, a crater-like ulcer forms and pain is reduced
necrotizing sialometaplasia diagnosis
biopsy (a malignant process must be excluded)
necrotizing sialometaplasia tx
heals in 5-6 weeks
primary herpetic gingivostomatitis category
infectious
primary herpetic gingivostomatitis etiology
initial infection of herpes simplex virus type 1 (HSV-1)
primary herpetic gingivostomatitis demographics
- usually in children 6 months to 6 years
- can occur in adults
primary herpetic gingivostomatitis clinical presentation
- acute onset
- may have fever and lymphadenopathy
- multiple small vesicles progress to ulceration of oral mucosa, lips and perioral skin
- painful, erythematous gingiva
primary herpetic gingivostomatitis diagnosis
- clinical diagnosis
- viral culture (slow) or PCR
- cytologic smear (least invasive, most cost effective)
- biopsy
primary herpetic gingivostomatitis tx
- lesions heal spontaneously in 2 weeks
- symptomatic relief (NSAIDs, lidocaine rinse)
- antiviral (should be administered during day 2 or 3 for best effect)
- HSV-1 remains latent in the trigeminal ganglion
cytologic smear steps
- lightly moisten tongue depressor with water
- gently remove cells (scrape) area
- spread accumulated cells on microscope slide
- spray slide lightly with fixative
- submit to pathologist
primary herpetic gingivostomatitis antiviral prescriptions
- Valacyclovir (Valtrex) 1 g
disp: 14 tabs
sig: 1 tab every 12h until finished - Acyclovir (Zovirax) 400 mg
disp: 21 tabs
sig: 1 tab three times a day until finished
recurrent herpes labialis category
infectious
recurrent herpes labialis etiology
- reactivation of HSV-1
- can recur multiple times
recurrent herpes labialis risk factors
- advanced age
- UV light
- physical/emotional stress
- dental treatment
