variation of normal that affects nonwhite individuals, particularly African Americans more often than other populations; appearance is due to harmless accumulations of glycogen in the surface cells; asymptomatic and appears bilaterally on the buccal mucos

leukoplakia

used to describe a suspicious white oral area that may be at increased risk for oral cancer

linea alba

commonly found bilaterally on the buccal mucosa along the line of occlusion, appears as a thickened white line in response to friction

mandibular torus

bony outgrowth found bilaterally on the lingual aspect of the mandibular alveolar bone most often in premolar area, a form of exostosis of unknown cause, although data suggest tori may be inherited

palatal torus

bony nodular growth present on the midline of the hard palate; common bony outgrowth of unknown cause, although data suggest tori may be inherited;

pregnancy tumor

lesion can be influenced by high school hormone levels such as puberty or during pregnancy; may appear as a smooth-surfaced or lobulated nodule

pyogenic granuloma

an uncommon but not rare blood vessel proliferation in response to local irritation, trauma, or poor oral hygiene

staging

of OSCC; procedure that determines how large the cancer is and whether it has spread to other parts of the body

acute inflammation

inflammation that begins suddenly and is short of duration less than 2weeks

alveolar bone proper

a thin layer of bone that supports the root and gives attachment to the periodontial ligament; aka lamina dura, cribriform plate

alveoli

Bony sockets

attached gingiva

portion of the gingiva attached to the alveolar bone by collagen fibers

bleeding on probing/ BOP

occurs with gentle probing of the ulcerated soft tissue wall of an inflamed pocket/sulcus; bleeding does not occur in health

cementoenamel junction/ CEJ

point where the cementum of the tooth of the tooth root and the enamel of the tooth crown meet; 60% of the time the cementum overlaps enamel; 30% of the time the cementum fails to meet the enamel, creating a small gap

chronic inflammation

a longer-lived inflammatory response that continues for more than a few weeks because the body is unable to resolve the infection

clinical attachment level/ CAL

measurement of the distance of the junctional epithelium from a fixed reference point, the cementoenamel junction, best single measurement of tooth support

col

a concave shaped depression in the papilla

collagen

tough, flexible, white material that provides strength and resilience and is a major component of all connective tissue, the most abundant protein in the body

exudate

aka suppuration; collection of dead white blood cells (neutrophils) that is indicative of infection; it may be a pearly white to a pale yellow

free gingiva

portion of the gingiva that is not attached to the tooth by gingival fibers, and forms the soft tissue wall of the gingival sulcus aka unattached gingiva

fremitus

palpable or visual movement of a tooth when in function because of hyper or traumatic occlusion

furcation

area where the roots of a tooth seperate, putting the tooth at greater risk for attachment loss and a poorer prognosis after periodontal therapy than teeth without furcation involvement

gingival crevicular fluid

an inflammatory exudate that results from the increased vascular permeability of inflamed gingival tissue

gingival recession

reduction of the gingival margin to a position apical to the cementoenamel junction exposing the root surface

refractory

indicates disease that is relatively non-responsive to repeated conventional treatment

suppuration

collection of dead white blood cells (neutrophils) that is indicative of infection; it may be a pearly white to a pale yellow also called exudate

tooth mobility

movement of a tooth that is greater than normal physiologic movement

Angle classification of malocclusion

system for classifying malocclusion based on the relationship of the maxillary first molar to the mandibular first molar and the relationship between the maxillary and mandibular canines, particularly when the first permanent molars are missing

spacing between the maxillary lateral and canine and the mandibular canine and first molar that is essential to allow the larger permanent teeth to erupt without difficulty

universal numbering system

uses numbers 1-16 for maxillary arch from right third molar to left third molar, then continues to mandibular arch on left third molar 17-32 ending at mandibular third molar on the right. primary dentition A-J and K-T.
