Terminology & Basics
STUDY
PLAY
bulla
elevated lesion more than 5mm diameter, usually contains serous fluid, looks like blister.
lobule
segment that's part of a whole. sometimes fused
macula
flat color difference. Ex=freckle
papule
small, circumscribed protrusion less than 1cm in diameter.
predunculated
stemlike or stalk base attachment. Opposite of sessile.
Like a mushroom!
pustules
elevation containing pus
sessile
base of lesion is flat or broad. Opposite of predunculated.
vesicle
small, elevated lesion less than 1cm diameter.
Contains serous (clear) fluid
nodule
palpable solid lesion. Above, same ground as, or below skin surface.
palpation
evaluation of lesion by feeling to determine texture or consistency. May be Soft, firm, semifirm, fluid filled!
colors
red, pink, salmon, white, blue-black, gray, brown & black=most frequently used to describe oral lesions.
erythema
abnormal redness of gingiva/mucosa
pallor
paleness of skin/mucosal tissues

corrugated
wrinkled
fissure
cleft or groove, shows depth
papillary
small, nipple-shaped projection/elevation found in clusters other than tongue
coalescence
parts join whole or fuse together to make one
diffuse
boders are not well defined.
multilocular
lesion extends beyond confines of distinct area. Resemble soap bubbles. Ex: Keratocyst
radiolucent
dark or black areas on radiograph. Soft tissue
internal resorption
pulpal tissue rxn from within tooth. Pulpal area can be seen as diffuse radiolucency beyond normal pulp area.
scalloping
as seen in cyst. Extends up PDL
unilocular
one unit=well defined
well circumscribed
exact margins

& Differential diagnosis
Examples of lesions that may be clinically diagnosed
fordyce granules
torus palatinus, mandibular tori,
melanin pigmentation
retrocuspid papillae
lingual varicosities
benign conditions of unknown cause
fissured tongue
median rhomboid glossitis
geographic tongue
hairy tongue
Radiographic diagnosis, sufficient info to est. Dx
PA pathosis
internal/external resorption
heavy interproximal calculus
dental caries
compound/complex odontoma
supernumerary teeth
impacted/unerupted teeth
calcified pulp
unusual radiographic findings
cubic zirconia, amalgam fragment, eyeglasses, amalgam overhang, instruments from root canal, curette, retained 1ary tooth, shotgun pellet, nose ring
pathologic conditions
amelogenesis imperfecta
dentinogenesis imperfecta
ulcerative colitis may lead to
oral ulcers
gingival enlargement due to
Tx with Ca channel blocker (Dylantin Hyperplasia)
skin graft, hip
white or brown pigmented area on mandibular ridge & vestibule
PA cemento-osseus dysplasia
black women 30-40 years old.
surgical Diagnosis
may appear as radiolucency that scallops
lingual mandibular bone cavity
well circumscribed, radiolucent area reveals salivary gland tissue entrapped during development
angular chelitis
may be B complex vitamin deficiency.
Most commonly fungal condition, Responds to Nystatin.
ANUG responds to
hydrogen peroxide
fordyce granules
clusters of ectopic sebaceous glands
torus palatinus
exotopic growth of normal compact bone, Inherited & occurs mainly in women
retrocuspid papilla
Sessile nodule, gingival margin on lingual mandibular cuspids. Looks like gums start a 2nd time
lingual varicosities
60 y.o.+ Ventral & Lateral surfaces tongue. Red-purple englarged vessles/clusters.
linea Alba
white line follows occlusion on cheek. May be more prominent in pts with clenching/bruxism habit
Leukoedema
generalized opalescence on buccal mucosa. More common in black adults. Dissipates when stretched!
lingual thyroid nodule
when thyroid tissue doesnt descend or remnants become trapped
geographic tongue
cause is not clear, may be genetic. Dorsal, lateral surfaces. Ectopic means may be found on areas other than tongue.
Fissured tongue
unknown cause, 5% of population. Genetic? deep fissures
Hairy tongue
^ accumulation Keratin on filiform papillae, white & hairy appearance.
