Terminology & Basics

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

cm

1/100 M

mm

1/1,000 M

10mm=

1 periodontal probe

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

diagnostic process

8 categories:
Clinical
Historical
Microscopic
Theraputic
Rad
Lab
Surg
& 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.
