Q

type of sensation associated with erythema migrans

A

burning sensation

22
Q

tx for erythema migrans

A

topical steroids for symptomatic lesions

23
Q

lichen planus

A

common oversensitivity to T lymphocytes

AI disease with unknown trigger

24
Q

how is lichenoid mucositis different than lichen planus

A

due to reaction to meds
graft vs host disease
may be focal or multifocal
but same microscopic and clinical appearance

25
Q

skin features of lichen planus

A

p’s:

planar, purple, pruritic, polygonal, plaque, papule

26
Q

describe the lesions of lichen plaus

A

multifocal, bilateral on buccal mucosa

27
Q

2 types of presentations of lichen planus

A
  1. reticular (wickhams stria - white lacey)

2. erosive (painful ulceration, wickhams striae can be present too)

28
Q

tx of reticular lichen planus

A

because they are asymptomatic, no tx occurs, but if there is burning, tx with topical corticosteroids

29
Q

tx of erosive lichen planus

A

topical corticosteroids

30
Q

clinical way to determine lichen planus or lichenoid mucositis

A

find out in the history if they have had a bone marrow transplant (graft vs host disease)
OR if it is unilateral reacting to amalgam

31
Q

nicotinic stomatitis

A

hot nicotine causing inflammation of the palate/minor salivary gland ducts
no premalignant potential

32
Q

t/f reverse smoker’s palate has a significant risk of dysplasia/carcinoma

A

true

33
Q

linea alba

A

variation of normal, where the teeth come together on the buccal mucosa
no tx

34
Q

morsicatio buccarum

A 
chronic cheek chewing
laborium = labial mucosa
linguarum = tongue
no tx (lateral acrylic shield
35
Q

leukoplakia

A

a white patch/plaque that cannot be characterized clinically as any other disease
only way to determine true diagnosis is with a biopsy and microscope

36
Q

t/f. leukoplakia is strictly a clinical term and implies a specific diagnosis

A

true, then false. it does NOT imply a specific diagnosis

37
Q

hyperkeratosis

A

callous, not premalignant, does not need removal

38
Q

epithelial dysplasia

A

premalignant

mild - not removed; moderate - can be removed; severe - remove

39
Q

t/f carcinoma in situ and superficial squamous cell carcinoma must be removed

A

true

40
Q

t/f. carcinoma in situ is confined to epithelium

A

true

41
Q

candida

A

most common oral fungal infection

component of normal oral microflora

42
Q

predisposing factors to candida

A

immunodeficiency, acquired immunosupression, endocrine disturbances, DM, corticosteroids, systemic sb therapy, xerostomia, bad hygiene

43
Q

pseudomembrane candidosis

A

thrush
white plaques that RUB OFF leaving a red base
pain or burning sensation

44
Q

tx of candidiasis

A

topical - nystatin rinse or ointment, clotrimazole rinse or troches, ketoconazole cream
systemic - ketoconazole or fluconazole tablets

45
Q

what can determine diagnosis of candida

A

cytology smear

46
Q

toothpaste slough is due to

A

sodium lauryl sulfate and pyrophosphates which can cause burning and look like gray/white plaques, but is more apparent in the morning

47
Q

burns are an area of…

A

yellow-white epithelial necrosis

48
Q

congenital cysts

A

developmental “inclusion” cysts

Epstein pearls or Bohns nodules (salivary) or gingival cysts of a new born

49
Q

tx of cysts

A

no tx

50
Q

fordyce granules

A

ectopic sebaceous (sweat) glands that appear as yellow, granular plaques and nodules

51
Q

tx of fordyce granules

A

none

52
Q

if something is classified as leukoplakia, it can be 1 of these 4 things

A

hyperkeratosis (most frequent)
epithelial dysplasia
carcinoma in situ
squamous cell carcinoma
