A circumscribed, elevated lesoins that is more than 5mm in diameter, usually contains serous fluid, and looks like a blister.
A segment or lobe that is a part of a whole; these lobes sometimes appear fused together.
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 surgace of the normal tissue.
A small, circumscribed lesion usually less than 1 cm in diameter that is elevated or protrudes above the surface or normal surrounding tissue.
Attached by a stemlike or stalklike base similar to that of a mushroom.
Variously sized circumscribed elevations containing pus.
Describing the base of a lesion that is flat or broad instead of stemlike.
A small, elevated lesion less than 1 cm in diameter that contains serous fluid.
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.
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; these terms also describe the consistency of a lesion.
An abnormal redness of the mucosa or gingiva
Paleness of the skin or mucosal tissues.
A cleft or groove, normal or otherwise, showing prominent depth.
Resembling small, nipple-shaped projections or elevations found in clusters.
The process by which parts of a whole join together, or fuse, to make one.
Describes a lesions 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.
Describes a lesion that extends beyond the confines of one distinct are and is defined as many lobes or parts that are somewhat fused together, making up the entire lesion; radiolucency is sometimes described as resembling soap bubbles
Describes the black or dark area on a radiograph; radiant energy can pass through these structures
Describes the light or white area on a radiograph that resuls from the inability of radiant energy to pass through the structure.
Observed 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 PDL.
Having one compartment or unit that is well defined or outlined; as in a simple radicular cyst.
Term used to describe a lesion with borders that are specifically defined and in which one can clearly see the exact margins and extend.
What are the eight categories that contribute to a diagnosis?
clinical, radiographic, historical, laboratory, microscopic, surgical, therapeutic, and differential findings
strength of diagnosis comes from the clinical appearance of the lesion on the basis of color, shape, location, and history
the radiograph provides sufficient information to establish a diagnosis
Typically combined with clinical, personal history, familiy history, past and present medical and dental histories, history of drug ingestion, and history of presenting disease or lesion
microscopic examination, biopsy, typically combined with clinical and history, brush biopsy common
blood chemistries and urinalysis, helpful in diagnosing oral infections
providing a therapeutic agent to treat a condition to confirm diagnosis, based on clinical and historical information
point in the diagnostic process when the practitioner decides which test or procedure is required to rule out the conditions originally suspected and establish the definitive or final diagnosis.
clusters of ectopic sebaceous glands, lips and buccal mucosa, tiny yellow lobules in clusters
exophytic growth of normal compact bone, may be lobulated
outgrowths of nromal dense bone found on the lingual aspect of the mandible in the area of the premolars above the mylohyoid ridge, usually bilateral, often lobulated or nodular, can appear fused together
most commonly observed in dark-skinned individuals
sessile nodule on the gingival margin of the lingual aspect of the mandibular cuspids
usually observed on the ventral and lateral surfaces of the tongue, clinically red to purple enlarged vessels or clusters are seen.
white line the extends anteroposteriorly on the buccal mucosa along the occlusal plane, may be bilateral
A generalized opalescence is transmitted to the buccal mucosa, gray white film diffused throughout the buccal mucosa, giving the mucosa a opaque quality. if the mucosa is stretched the opalescence becomes less prominent
diffuse epidermal hyperplasia, implies increased thickness of stratum spinosum
Lingual thyroid nodule
clinically observed as a mass in the midline of the dorsal surface of the tongue posterior to the circumvallate papillae in the area of the foramen cecum. usually has a sessile base and is 2-3 cm in width
Median rhomboid glossitis
may be associated with chronic fungal infections by Candida albicans, clinically appears as a flat or slightly raised oval or rectangular erythematous area in the midline of the dorsal surface of the tongue, beginning at the junction of the anterior and middle thirds and extending posterior to the circumvallate papillae, devoid of filiform papillae; therefore texture is smooth
clinical appearance involves the dorsal and lateral borders of the tongue, diffuse areas devoid of filiform papillae can be observed, these area as erythematous patches that are surrounded by a white or yellow perimeter, the fungiform papillae appear distinct within the erythematous patch, condition does not remain static
What is geographic tongue also known as?
erythema migrans and benign migratory glossitis
Ectopic geographic tongue
like geographic tongue, but found on other mucosal surfaces other than the tongue
clinically the dorsal surface of the tongue appears to have deep fissures or grooves that may become irritated if food debris collects in them
increased accumulation of keratin on the filiform papillae, this may be due to an increase of keratinization or a decrease in normal desquamation.
Black hairy tongue
Same as white hairy tongue, but black to brown chromogenic bacteria exist on the papillae
