Exam 1 Flashcards
Bulla
A circumscribed, elevated lesion that is more than 5 mm in diameter
Usually contains serous fluid, and looks like a blister
Lobule
A segment or lobe that is part of a 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
Nodule
A palpable solid lesion up to 1 cm in diameter found in soft tissue
Can occur above, level with, or beneath the skin surface
papule
A small, circumscribed lesion usually less than 1 cm in diameter
It 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
Describes 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
erythema
abnormal redness
erythroplakia
Appears as a smooth red patch or granular, red, velvety patch
Can NOT be rubbed off or diagnosed as a specific disease
pallor
paleness
leukoplakia
White patch or plaque-like lesion
Can NOT be rubbed off or diagnosed as a specific disease
corrugated
wrinkled
papillary
Small finger-like projections or elevations found in clusters
verrucose
Warty, often with a rough surface
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
well circumscribed
Used to describe a lesion with borders that are specifically defined and in which one can clearly see the exact margins and extent
multilocular
Describes a lesion that extends beyond the confines of one distinct area
Defined as many lobes or parts that are somewhat fused together
A multilocular radiolucency is sometimes described as resembling soap bubbles
uniocular
Having one compartment or unit that is well defined or outlined as in a simple radicular cyst
fordyce granules
Clusters of ectopic sebaceous glands
Appear as yellow lobules in clusters
Commonly observed on vermilion border of lips and buccal mucosa
No treatment
More than 80% of adults over 20 years old have
torus palatinus
An exophytic growth of normal compact bone
Observed clinically in midline of hard palate
Inherited, gradual formation
More common in women
May take on various shapes and sizes, may be lobulated, and is covered by normal soft tissue
Treatment
None, unless they interfere with speech, swallowing, or a prosthetic appliance
(an example of exostosis)
mandibular tori
Outgrowths of 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
Have no predilection for either sex
No treatment unless they interfere with fabrication and placement of a prosthodontic appliance
melanin pigmentation
The pigment that gives color to skin, eyes, hair, mucosa, and gingiva
Most commonly observed in dark-skinned individuals
lingual varicosities
Clinical appearance
Red-to-purple enlarged vessels or clusters
Usually observed on the ventral and lateral surfaces of the tongue
Most commonly observed in individuals older than 60 years
linea alba
A “white line” extends anteroposteriorly on the buccal mucosa along the occlusal plane
May be bilateral
May be more prominent in patients who have a clenching or bruxing habit
leukodema
A generalized opalescence on the buccal mucosa
Most commonly observed in black adults
If the mucosa is stretched, the opalescence becomes less prominent
No treatment
Up to 90% of cases are observed in black adults.
Median Rhomboid Glossitis (Central Papillary Atrophy)
Flat or slightly raised oval or rectangular erythematous area in center of tongue
May be associated with a chronic infection with Candida albicans
No treatment necessary, but antifungal treatment may be used
Erythema Migrans/Benign Migratory Glossitis(Geographic Tongue)
Erythematous patches surrounded by a white or yellow border
Diffuse areas devoid of filiform papillae
Distinct presence of fungiform papillae
Ectopic can occur on other muciosal tissues
No treatment needed
Fissured Tongue(Scrotal Tongue)
Clinical appearance
The dorsal surface of the tongue appears to have deep fissures or grooves
Cause: Unknown
Probably involves genetic factors
Seen in about 5% of the population
white hairy tongue
Clinical appearance
Elongated filiform papillae are white
Result of either an increase in keratin production or a decrease in normal desquamation
Home care
Direct the patient to brush the tongue gently with a toothbrush to remove debris
Black hairy tongue
Clinical appearance
Papillae are brown-to-black because of chromogenic bacteria
Contributing factors
Tobacco
Foods
Hydrogen peroxide
Alcohol
Chemical rinses
Home care
Direct the patient to brush the tongue gently with a toothbrush to remove debris
inflammation
Nonspecific response that allows the body to eliminate injurious agents, contain injuries, and heal defects
Extent and duration of injury → determine extent and duration of inflammatory response
local inflammation
one area
systemic inflammation
whole body
classic signs of inflammation localized
Redness
Heat
Swelling
Pain
Loss of normal tissue function
classic signs of inflammation systemic
Fever
Leukocytosis
Elevated C-reactive protein (CRP)
Lymphadenopathy
pyrogens
a fever over 98.6
Leukocytosis
Increase in #WBCs (10,000-30,000)
Normal= 4,000-10,000
Elevated C-reactive protein
Protein produced in liver
Lymphadenopathy
Enlarged lymph nodes
Results from hyperplasia & hypertrophy of lymphocytes
hyperplasia
enlargement of tissue from increased NUMBER of cells
Hypertrophy
enlargement of tissue from increased SIZE of its cells
inflammation sequence
-injury to tissue
-constriction of microcirculation
-dilatation of microcirculation
-increased permeability
-exudate leaves
-increased blood viscosity
-decreased blood flow
-margination and pavementing of WBC
-WBC’s enter tissue
-WBC’s ingest foreign material
hyperplasia
An increase in the number of cells, often in response to chronic irritation or abrasion
May return to normal if the insult subsides, or may persist after removal of the irritant
hypertrophy
An increase in the size of cells
May be seen in cardiac muscle as a response to hypertension
Atrophy
A decrease in size or function of a cell, tissue, organ, or entire body
