Terminology & Basics
elevated lesion more than 5mm diameter, usually contains serous fluid, looks like blister.
segment that's part of a whole. sometimes fused
flat color difference. Ex=freckle
small, circumscribed protrusion less than 1cm in diameter.
stemlike or stalk base attachment. Opposite of sessile.
Like a mushroom!
elevation containing pus
base of lesion is flat or broad. Opposite of predunculated.
small, elevated lesion less than 1cm diameter.
Contains serous (clear) fluid
palpable solid lesion. Above, same ground as, or below skin surface.
evaluation of lesion by feeling to determine texture or consistency. May be Soft, firm, semifirm, fluid filled!
red, pink, salmon, white, blue-black, gray, brown & black=most frequently used to describe oral lesions.
abnormal redness of gingiva/mucosa
paleness of skin/mucosal tissues
1 periodontal probe
cleft or groove, shows depth
small, nipple-shaped projection/elevation found in clusters other than tongue
parts join whole or fuse together to make one
boders are not well defined.
lesion extends beyond confines of distinct area. Resemble soap bubbles. Ex: Keratocyst
dark or black areas on radiograph. Soft tissue
pulpal tissue rxn from within tooth. Pulpal area can be seen as diffuse radiolucency beyond normal pulp area.
as seen in cyst. Extends up PDL
one unit=well defined
& Differential diagnosis
Examples of lesions that may be clinically diagnosed
torus palatinus, mandibular tori,
benign conditions of unknown cause
median rhomboid glossitis
Radiographic diagnosis, sufficient info to est. Dx
heavy interproximal calculus
unusual radiographic findings
cubic zirconia, amalgam fragment, eyeglasses, amalgam overhang, instruments from root canal, curette, retained 1ary tooth, shotgun pellet, nose ring
ulcerative colitis may lead to
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.
may appear as radiolucency that scallops
lingual mandibular bone cavity
well circumscribed, radiolucent area reveals salivary gland tissue entrapped during development
may be B complex vitamin deficiency.
Most commonly fungal condition, Responds to Nystatin.
ANUG responds to
clusters of ectopic sebaceous glands
exotopic growth of normal compact bone, Inherited & occurs mainly in women
Sessile nodule, gingival margin on lingual mandibular cuspids. Looks like gums start a 2nd time
60 y.o.+ Ventral & Lateral surfaces tongue. Red-purple englarged vessles/clusters.
white line follows occlusion on cheek. May be more prominent in pts with clenching/bruxism habit
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
cause is not clear, may be genetic. Dorsal, lateral surfaces. Ectopic means may be found on areas other than tongue.
unknown cause, 5% of population. Genetic? deep fissures
^ accumulation Keratin on filiform papillae, white & hairy appearance.
