Chapter 1- Intro To Oral Lesions Flashcards
Lobule
A segment or lobe that is part of the whole; these lobes sometimes appear fused together.
Bulla
A circumcised, elevated lesion that is more then 5 mm in diameter or, usually contains serous fluid, and looks like a blister.
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.
Papule
A small, circumcised Lesion usually less than 1 cm in diameter or that is elevated or protrudes above the surface of a normal surrounding tissue.
Pedunculated
Attached by a stem-like or stalk-like 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
Nodule
A palpable solid lesion up to 1 cm in diameter found in soft tissue; it can occur above, level with, or beneath the skin surface.
Palpating
The evaluation of a lesion by feeling it with the fingers to determine the texture of the area; the discriptive terms for palpating are soft, firm, semi-firm, and fluid filled. These are terms also describe the consistency of a lesion.
Erythema
An abnormal redness of the oral mucosa or gingiva
Pallor
Paleness of the skin or oral tissues
Corrugated
Wrinkled
Fissure
A cleft or groove, normal or otherwise, showing prominent depth.
Papillary
Resembling small, nipple-shaped projections or elevations found in clusters
Coalescence
The 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; this may make treatment more difficult and, depending on the biopsy results, more radical.

Multiocular
Describes a lesion that extends beyond the confines of one distinct area and is defined as many lubes or parts that are somewhat fused together, making up the entire lesion; a multiocular radiolucency is sometimes described as a resembling soap bubbles; and odontogenic keratocyst cyst often presents a multiocular, radiolucent lesion.
Radiolucent
Describes the black or dark areas on a radiograph; radiant energy can pass through the structures; less dense tissue such as pulp is seen as a radiolucent structure.
Root resorption
Observed radiographically when the apex of the tooth appears shortened or blunted and your regularly sheet; occurs as a response to stimuli, which can include a cyst, tumor, or trauma; external resorption arises from tissues outside the tooth such as the periodontal ligament where as internal resorption is triggered by pulps like tissue reaction from with in the tooth; in the latter the pulp area can be seen as a diffuse radiolucency beyond the confines of the normal pulp area.
Scalloping around the root
A radiolucent lesion that extends between the roots, and seen in a traumatic bone cyst; this lesion appears to extend the periodontal ligament.
Unilocular
Having one compartment or unit that is well defined were outlined, as in a simple radicular cyst.
After arriving at a differential diagnosis, information from which one of the following categories the best establish a final or definitive diagnosis?
Microscopic
