Oral Pathology Ch 1

Front 1

Bulla, bullous

Back 1

a circumscribes, elevated lesion that is more than 5mm in daimeter, usually contains serous fluid, and looks like a blister

Front 2

lobule

Back 2

a segment or lobe that is part of the whole, these lobes sometime appear fused together

Front 3

macule

Back 3

an area that is usually distinguished by a color different from the surrounding tissue, it is flat and does not protrude above the surface of normal tissue. a freckle is an example of this

Front 4

papule

Back 4

a small circumscribed lesion usually less than 1mm in diameter that is elevated or protrudes above the surface of the normal surrounding tissue

Front 5

pedunculated

Back 5

attached by a stemlike of stalk base similar to that of a muchroom

Front 6

pustules

Back 6

various sized circumscribed elevations containing pus

Front 7

sessile

Back 7

describing the base of a lesion that is flat or broasd instead of stemlike

Front 8

vesicle

Back 8

a small, elevated lesion less than 1cm in diameter that contains serous fluid

Front 9

nodule

Back 9

a palpable solid lesion up to 1 cm in diameter founf in soft tissue it can occur above level with or beneath the skin

Front 10

palpation

Back 10

the elevation of a lesion by feeling it with the fingers to determine the texture of the area the descriptive term for palpation arc soft, firm semi/inn and fluid filled these terms also describe the consistency of a lesion

Front 11

corrugated

Back 11

wrinkled

Front 12

fissure

Back 12

a cleft or groove normal or otherwise showing prominent depth

Front 13

papillary

Back 13

resembling small nipple shaped projections or elevations found in clusters

Front 14

smooth, rough, folded

Back 14

terms to describe the surface texture of a lesion

Front 15

erythema

Back 15

an abnormal redness of the mucosa or gingiva

Front 16

pallor

Back 16

paleness of the skin or mucosa

Front 17

centimeter

Back 17

Front 18

millimeter

Back 18

one thousandth of a meter

Front 19

coalescence

Back 19

the process by which parts of a whole join together or fuse to make one

Front 20

diffuse

Back 20

describes a lesion with boarders that are not well defined making it impossible to detect the exact parameter of the lesion this may make treatment more difficult and depending on the biopsy results more radical

Front 21

multiocular

Back 21

describes a lesion that extends beyond the confines of one distinct area and is defined as many lobules or parts that are somewhat fused together making up the entire lesion a multiocular radiolucency is sometimes describel as resembeling soap bubbles and odontogenic kerarocyst often presented as a multiocular, radiolucent lesion

Front 22

radiolucent

Back 22

describes the black ageas on the radiograph radient energy can pass through these structures less dense tissue such as pulp is seen as a radiotranslucent structure

Front 23

radiolucent and radiopaque

Back 23

terms used to describe a mixture of light and dark areas within a lesion usually denoting a stage in the lesion's development

Front 24

radiopaque

Back 24

describes the light or white areas on a radiograph that results from the inability of radient energy to pass throught the structures the more dense the structure the more light or white it appears on the radiograph

Front 25

root resorption

Back 25

on radiograph when the apex of a tooth appears shortened blunted or irregularly shaped

Front 26

scalloping aroung the root

Back 26

a radiolucent lesion that extends between the roots as seen in a traumatic bone cyst this lesion appears to extend up the periodontal ligament

Front 27

unilocular

Back 27

having one compartment or unit that is well defined or outlined as in a simple radicular cyst

Front 28

well circumscribed

Back 28

term used to describe a lesion with boarders that are specifically defined and in which one can clearly see the exact margins and extent
