Lecture Summary: Reactive Disorders Flashcards
linea alba
- _______ in the buccal mucosa at the level of the ______
- cause = ______
- Tx or no Tx?
- white line, occlusal plane
- pressure, friction, sucking trauma
- No Tx
shredded-appearing lesion on buccal mucosa (can also occur on tongue)
morsicatio buccarum
erosion of upper layer of mucosa, usually showing yellowing fibrin at center surrounded by red mucosa
traumatic ulceration
- cause of morsicatio buccarum
- Tx or no Tx?
- habitual chewing of the cheek (stress, psychological)
- No need for Tx
- cause of traumatic ulceration
- Tx or no Tx?
- accidental trauma, ill fitting dentures
- if ulcer persists for a month+ after removing source of irritation, must biopsy to rule of malignancy
four causes of burns
- electricity
- heat
- chemicals used by patients
- chemicals used by dentists
Inflammation of salivary gland ducts; appears as red, raised papules on palate
nicotine stomatitis
- nicotine stomatitis cause
- Tx or no Tx?
- caused not by nicotine but by heat
- No need for Tx
blue-grey pigmented lesion on or adjacent to alveolar ridge
amalgam tattoo
cause of amalgam tattoo
migration of amalgam material into tissue
brown discoloration on gingiva, floor of mouth, buccal mucosa, palate, lips in heavy smoker
smoker’s melanosis
cause of smoker’s melanosis
accumulation of melanin (which helps detoxify nicotine and other bad stuff)
fast-growing brown patch on buccal mucosa
melanoacanthoma
melanocanthoma
- more common in _____. seen almost exclusively in ______
- cause = _____
- females, black people
- unknown
actinic means….
sun induced
Cheilitis means…
inflammation of the lips
initially, this is just blurring of the margin between lip and skin; later see scaling, redness, and
ulceration.
actinic cheilitis
actinic cheilitis is _______, but can easily turn _____
not malignant, malignant
Small, firm bump on the gingiva or any place susceptible to trauma (e.g., buccal mucosa and
tongue due to chronic biting)
peripheral fibroma
options for peripheral fibroma
leave it alone or surgically remove if it’s annoying the patient
- dark red, fast-growing, ulcerated gingival nodule.
- more common in younger patients; sometimes seen in pregnancy.
- not really a granuloma
pyogenic granuloma
options for pyogenic granuloma
may spontaneously disappear; otherwise, remove surgically
- red to purple gingival nodule
- actually a granuloma
peripheral giant cell granuloma
options for peripheral giant cell granuloma
needs to be removed surgically all the way down to the underlying bone
- more common in younger patients
- red, ulcerated gingival nodule
- calcifications or bony tissue
- not really a fibroma
peripheral ossifying fibroma
options for peripheral ossifying fibroma
needs to be removed surgically all the way down to the underlying bone
fluid-filled, dome-shaped lesion usually on the lower lip; caused by traumatic rupture of salivary gland duct, resulting in spillage of mucin into adjacent
tissue
mucocele
- a cyst is just a fluid-filled sac-like structure lined by epithelium.
- salivary duct cysts form adjacent to salivary ducts and contain mucin.
salivary duct cyst
the abnormal formation of stones (calcium
deposits) within salivary glands.
sialolithiasis
