morphological variations of oral mucosa Flashcards
geographic tongue - aetiology
unknown
geographic tongue - clinical
appear, heal, develop elsewhere
demarcated erythema - desquamation of filiform papillae
surrounding white/yellow serpentine borders - filiform papillae in regeneration
often anterior 2/3
geographic tongue - what systemic condition may it be linked with?
psoriasis
geographic tongue - histology
red area - atrophic filiform papillae
white area - hyperkeratosis and acanthosis
geographic tongue - tx
none
reassure
avoid spicy food
mild topical CS if severe
fissured tongue and crenations - clinical
1 deep central +/- radial fissures: dorsum
crenations - lateral border indentations due to extended/forceful contact with teeth
fissured tongue and crenations - what oral condition can it be associated with?
geographic tongue
fissured tongue and crenations - tx
none - asymptomatic
avoid spicy/acid food if sore
fissured tongue and crenations - links to other diseases
Melkersson-Rosenthal syndrome
Down syndrome
Cowden Syndrome
psoriasis
Melkersson-Rosenthal Syndrome
facial/lip swelling (granulomatous cheilitis)
facial paralysis
fissured tongue
hairy tongue - aetiology
smoking poor OH AB therapy c albicans MW systemic steroids radiotherapy
hairy tongue - clinical
dorsum hairlike appearance
yellow/brown/black depending on diet and cause, bacterial pigmentation
sometimes gagging sensation/metallic taste
debris between elongated papillae = halitosis
hairy tongue - histopathology
hypertrophy of filiform papillae, subjacent inflammation
linked to excessive keratin production/failure of epithelial cells or keratin layer to desquamate
hairy tongue - tx
none
eliminate RFs
brush tongue with Na bicarb and water
lingual fimbriae
normal
small filiform flanges ventral tongue
parallel to and on either side of lingual frenulum
represent non-completely absorbed tissue during tongue development
if hyperplastic can confuse with squamous papillomas
what are lingual varices?
enlargement of small veins ventral tongue (rarely lips and FOM)
tx of lingual varices
none - asymptomatic
lingual varices factors
- ageing - degeneration of collagen elastic fibre
- hypertension
- dentures
ankyloglossia pathogenesis
developmental anomaly
inferior frenulum too short, restricts tongue movement
- complete/partial fusion with STs FOM
varying severity - length of frenulum
