Oral pathology Flashcards
Bulla
Circumscribed, elevated lesion that is more than 5 mm in diameter usually contains serous fluid, looks like a blister
Lobule
Segment or lobe that is a part of a whole; sometimes appear fused together
Macule
Area distinguished by a different color than the surrounding tissue, Flat. EX: freckle
Papule
Small, circumscribed lesion less than 1 cm in diameter, elevated or protrudes above the surface of Normal surrounding tissue
Pedunculated
Attached by stem or stalk like similar to mushroom/ broccoli
Pustules
Varies in sizes, circumscribed elevation contains pus
Sessile
Base of the lesion is flat or broad
Vesicle
Small elevated lesion less than 1 cm in diameter contains serous fluid
Nodule
Palpable solid lesion up to 1 cm in diameter in soft tissue, Can be above, level with or below skin surface
Palpation
Evaluation of the lesion by feeling,
Descriptive terms for palpation
Soft, firm, semi firm, fluid filled
Colors for lesions
Red, pink, salmon, white, blue-black, gray, brown, and black
Erythema
Abnormal redness of the mucosa or gingiva
Erythroplakia
Lesion that appears smooth red patch, granular red, and velvety patch
Leukoplakia
White plaque like lesion on the mucosa that can not be rubbed off or diagnosed as a specific disease
Pallor
Paleness of the skin or oral mucosa
Corrugated
Wrinkled
Fissure
Cleft or groove, normal otherwise maybe showing prominent depth
Papillary
Resembling small nipple shaped projection or elevation found in clusters
descriptive terms for texture of lesion
Smooth,rough, folded
Coalescence
Process by which parts of a whole join together to or fuse to make one
Diffuse
Lesion with borders that are not well defined
Multi ocular
Lesion that extends beyond the confines of a distinct area and has many lobes or parts that fuse together
Radiolucent
Dark area; radiant energy can pass through less dense tissue such as the pulp
Radiolucent and radiopaque
In stage 1 periapical cemento-osseous dysplasia is Radiolucent
In stage 2 it is Radiolucent and radiopaque
Radiopaque
Light or white; inability of radiant energy to pass through structure
Root resorption
Apex of tooth short, blunted, and irregular shape; response to a stimuli (cyst, tumor, or trauma
Scalloping around the root
Radiolucent lesion extending between the roots; traumatic bone cyst; extends up to periodontal ligament
Unilocular

Well circumscribed
Border that are specifically define; can be seen clearly the margins and extent
Anomaly
Deviates from the standard
Dysphagia
Difficulty swallowing
Dysphonia
Difficulty speaking
Dyspnea

8 categories that lead to definitive or final diagnosis
1) clinical
2) radiographic
3)historical
4)laboratory
5) microscopic
6)surgical
7) therapeutic
8) differential
Clinical diagnosis
By observation; Fordyce granules, Torus palatines, Mandibular tori, melanin Pigmentation, Retrocuspid papillae, and lingual varicosities
Unknown causes that are recognized by clinical appearance
