Oral Med Tutorial 1 Flashcards
what is the epidemiology of OLL
middle-aged females
what is the clinical presentation of OLL (4 points)
mostly in buccal mucosa
unilateral
white striations, plaques, erythema, ulcers or blisters
asymptomatic or sensitivity to spicy foods
what are the four differences between OLL and OLP
OLL singular lesions in localised area
OLL appears on less well established sites also (gingiva)
OLL has an aetiological cause
OLL has higher malignancy transformation rate
what is the pathogenesis of OLP
T cell mediated
autoimmune disease
triggering apoptosis of basal cell layer of epithelium
what are the six clinical subtypes of OLP
reticular
plaque like
atrophic
erosive
papular
bullous
what is the most recognised form of OLP
reticular lesions which appear as a network of connecting and overlapping lines - Wickham’s striae
how does erosive OLP present
erythema caused by inflammation or epithelial thinning
how does plaque like OLP present
mimics leukoplakia
appears as white, homogenous elevated multifocal smooth lesion
name four histological features of OLP
mixed superficial infiltrate
limited to lamina propria
more vascularity
more granulated mast cells in basement membrane degradation area
name four histological features of OLL
strict lymphohistocytic infiltrate
deeper distribution to lamina propria and superficial submucosa
no vascularity
focal interruption of the granular later
name three potential causes of OLL
restorative materials
GVH disease
hepatitis C
what is the cause of OLP
inflammatory auto-immune type disease affecting stratified squamous epithelium
how do OLLs commonly present that allows them to be differentiated from OLP
unilateral
asymmetrical
associated with erosions
name three features of OLP histology
hyper or parakeratosis
degeneration of the basal layer
T-lymphocytes hugging the basal layer
what is the treatment plan for patients with asymptomatic OLP
reassure
monitor
avoid risk factors
