Exam One, Chapter One Flashcards
*A circumscribed, elevated lesion that is MORE THAN 5 mm in diameter *Usually contains serous fluid, and looks like a blister
bulla
*A segment or lobe that is part of a whole *These lobes sometimes appear fused together
lobule
*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 EXAMPLE: FRECKLE
macule
* A small, circumscribed lesion usually less than 1 cm in diameter *It is elevated or protrudes above the surface of normal surrounding tissue
papule
Variously sized circumscribed elevations containing pus
pustule
A small, elevated lesion less than 1 cm in diameter that contains serous fluid
vesicle
Attached by a stemlike or stalklike base similar to that of a mushroom
pedunculated
Describes the base of a lesion that is flat or broad instead of stemlike
sessile
*A palpable solid lesion up to 1 cm in diameter found in soft tissue *Can occur above, level with, or beneath the skin surface
nodule
The evaluation of a lesion by feeling it with the fingers to determine the texture of the area
palpation
What are the descriptive terms for palpation?
soft, firm, semifirm, and fluid filled
What are the most frequent colors of lesions?
red, pink, slamon, white, blue-black, gray, brown, and black
An abnormal redness of the mucosa or gingiva
erythema
A clinical term used to describe an oral lesion that appears as a smooth red patch or granular red and velvety patch. It is less common than leukoplakia
erythroplakia
Paleness of the skin or mucosal tissues
pallor
A clinical term for a white, plaquelike lesion on the oral mucosa that cannot be rubbed off or diagnosed as a specific disease
leukoplakia
what are the sizes of the lesions measured in?
cm or mm
Wrinkled
corrugated
a cleft or groove, normal or otherwise, showing prominent depth
fissure
resembling small, projections or elevations found in clusters
papillary
What can the surface textures be on a lesion?
corrugated, fissured, papillary, smooth, rough, and folded
The process by which parts of a whole join together, or fuse to make one
coalescence
Describes a lesion with borders that are not well defined, making it impossible to detect the exact parameters of the lesion
diffuse
*Describes a lesion that extends beyond the confines of one distinct area *defined as many lobes or parts that are somewhat fused together “soap bubbles” radigraphically
Multilocular
Radiographically, the apex of the tooth appears shortened or blunted and irregularly shaped. Occurs as a response to stimuli, like a cyst, tumor, or trauma
root resorption
Arises from tissue outside of the tooth, such as the periodontal ligament
external root resorption
*triggered by pulpal tissue reaction from within the tooth *The pulpal area can be seen as a diffuse radiolucency beyond the confines of the normal pulp area
internal root resorption
A radiolucent lesion that appears to extend up the periodontal ligament and between the roots
scalloping around the root
Having one compartment or unit that is well defined or outlined as in a simple radicular cyst
unilocular
used to described a lesion with borders that are specifically defined and in which one can clearly see the exact margins and extent
well circumscribed
Something that deviates form what is normal
anomaly
dysphagia
difficulty swallowing
dysphonia
difficulty speaking
dyspnea
difficulty breathing
What is the brush test?
It is used to obtain information from oral mucosal epithelium. A circular brush is used to obtain cells from the full thickness of the epithelium.
Can a white lesion be diagnosed on the basis of clinical appearance alone?
NO
*May appear as a radiolucency that scallops around the roots *when the lesion is opened surgically, an empty void is found
Traumatic bone cyst
Surgical examination of the well-circumscribed, radiolucent area reveals salivary gland tissues entrapped during development
Lingual mandibular bone cavity (static bone cyst)
What are common conditions to be diagnosed by therapeutic means?
nutritional deficiencies
*may be associated with a deficiency of B-complex vitamins *most commonly a fungal condition and responds to topical application of an antifungal cream or ointment such as Nystatin
Anular cheilitis
Responds to hydrogen peroxide, very painful, and is stress induced
Necrotizing ulcerative gingivitis (NUG)
That point in the diagnostic process when the practitioner decides which test or procedure is required to rule out the conditions originally suspected and to establish the definitive or final diagnosis
Differential Diagnosis
*Clusters of ectopics sebaceous glands *Appear as yellow lobules in clusters *commonly observed on vermillion border f lips and buccal mucosa *NO TREATMENT
fordyce granules
The pigment that gives color to skin, eyes, hair, mucosa, and gingiva. This is most commonly observed in dark-skinned individuals
Melanin pigmentation
* A sessile nodule on the gingival margin of the lingual aspect of the mandibular cuspids * Only a few mm in size *observed more often in young *Resolves with age
Retrocuspid papilla
*red to purple enlarged vessels or clusters *Usually observed on the ventral and lateral surfaces on the tongue * Most commonly observed in ppl 60 and older
Lingual varicosities
*A generilized opalescence on the buccal mucosa *Most common in black adults *If mucosa is stretched, it is less prominent * NO TREATMENT
Leukoedema
Undescended, trapped remnant of thyroid tissue. 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 a sessile base and is 2-3 cm in width
lingual thyroid
What is the predilection of lingual thyroid?
females and linked to hormonal changes
What is the treatment for lingual thyroid?
Evaluation of patient to see whether the thyroid gland is present in its normal location
