Chapter 1 Flashcards
Bulla(adjective, bullous; plural, bullae)
A circumscribed, elevated
lesion that is more than 5 mm in diameter, usually contains
serous fluid, and looks like a blister.
Lobule (adjective, lobulated)
A segment or lobe that is a part of the
whole; these lobes sometimes appear fused together
Macule
An area that is usually distinguished by a color different
from that of the surrounding tissue; it is flat and does not
protrude above the surface of the normal tissue. A freckle is an
example of a macule.
Papule
A small, circumscribed lesion usually less than 1 cm in
diameter that is elevated or protrudes above the surface of
normal surrounding tissue.
Pedunculated
Attached by a stemlike or stalklike base similar to
that of a mushroom
Pustules
Variously sized circumscribed elevations containing pus.
Sessile
Describing the base of a lesion that is flat or broad instead
of stemlike
Vesicle
A small, elevated lesion less than 1 cm in diameter that
contains serous fluid.
Unilocular
Having one compartment or unit that is well defined or outlined, as in a simple radical argument cyst.
Well circumscribed
Term used to describe a lesion with borders that are specifically defined an in which one can clearly see the exact margins and extent.
Anomaly
Something that deviates from what is standard or normal.
Pallor
Paleness of the skin or mucosal tissues.
Centimeter (cm)
One-hundredth of a meter; equivalent to a little less than one-half inch (0.393 inch). If a lesion is described as being 3 cm in size, it is really about one and a half inches.
Millimeter (mm)
One-thousandth of a meter (a meter is equivalent to 39.3 inches); the periodontal probe is of great assistance in documenting the size or diameter of a lesion and is measured in millimeters.
Corrugated
wrinkled
Fissure
a cleft or groove, normal or otherwise showing prominent depth
Papillary
resembling small, nipple-shaped projections or elevations found in clusters
Palpation
The evaluation of a lesion by feeling it with the fingers to
determine the texture of the area the descriptive terms for
palpation are soft, firm, semifirm, and fluid filled (fluctuant); these
terms also describe the consistency of a lesion.
Colors
Red, pink, salmon, white, blue-black, gray, brown, and black
are the words used most frequently to describe the colors of oral
lesions; they can be used to identify specific lesions and may also
be incorporated into general descriptions.
Erythema
An abnormal redness of the mucosa or gingiva
Dysphagia
Difficulty swallowing
Disphonia
Difficulty speaking
Dyspnea
Difficulty breathing
Smooth, Rough, Folded
Used to decribed the surface texture of a lesion
Coalescence
Process by which parts of a whole join together, or fuse, to make one
Diffuse
Describes a lesion with borders that are not well defined, making it impossible to detect the exact parameters of the lesion
Multilocular
Describes a lesion that extends beyond the confines of one distinct area and is defined as many lobes or parts that are somewhat fused together, making up the entire lesion; a multilocular radiolucency is sometimes described as resembling soap bubbles.
Radiolucent
Describes the black or dark areas on a radiograph; radiant energy can pass through these structures; less dense tissue such as the pulp is seen as a radiolucent structure.
Radiolucent and radiopaque
Terms used to describe a mixture of light and dark areas within a lesion, usually denoting a stage in the development of a lesion.
Radiopaque
Describes the light or white area on a radiograph that results from the inability of radiant energy to pass through the structure, the denser the structure, the lighter or whiter it appears on the radiograph
Root resorption
Observes radiographically when the apex of the tooth appears shortened or blunted and irregularly shaped; occurs as a response to stimuli, which can include a cyst, tumor, or trauma.
Scalloping Around The Root
A radiolucent lesion that extends between the roots, as seen in a traumatic bone cyst; this lesion appears to extend up the periodontal ligament
Erythema
Redness of mucosa or gingiva
Erythroplakia
Oral mucosa lesion that is a smooth red patch or velvety patch
Leukoplakia
White plaque like lesion that cannot be rubbed off
