Dental Tech. Vol. 1

Front 1

What is the crown of the tooth?

Back 1

The anatomical crown is that portion of the tooth encased in enamel. The clinical crown is applied to the part of the crown exposed in the mouth.

Front 2

What is the root of the tooth?

Back 2

The root of the tooth is embedded in alveolar bone and is covered by cementum.

Front 3

What is the cervix of the tooth?

Back 3

Slight indentation that encircles the tooth and marks the junction of the crown with the root.

Front 4

What is the term for a tooth with two roots?-three roots?

Back 4

bifurcated- trifurcated

Front 5

Cementum

Back 5

bonelike tissue that covers the roots of the teeth in a thin layer. joins the enamel and the cervix of the tooth at the cementoenamel junction.

Front 6

The dental pulp

Back 6

soft tissue of the tooth which develops from the connective tissue of the dental papilla.

Front 7

The alveolar process

Back 7

bony portion of the maxilla and mandable where the teeth are embedded and by which tooth roots are supported

Front 8

Periodontium

Back 8

the tissues that surround and support the teeth. thier main purpose is to support, protect, and provide nurishment for the teeth.

Front 9

cortical plate (portion of alveolar process)

Back 9

the cortical plate is composed of ligual and facial plates of compact bone.provides strength and protection and acts as attachment for skeletal muscles.

Front 10

alveolar crest

Back 10

highest point of the alveolar ridge and joins the facial and lingual cortical plates.

Front 11

trabecular bone

Back 11

trabecular or spongy bone lies within the central portion of the alveolar process and is the less dense canellous bone.

Front 12

alveolar bone proper

Back 12

thin layer of compact bone that is a specialized continuation of the cortical plate & forms the tooth socket

Front 13

cementum

Back 13

the only tissue considered as both part of the tooth and the periodontium.functions as an area of attachment for the periodontal ligament fibers.

Front 14

periodontal ligaments

Back 14

thin, fibrous ligament that connects the bone to the socket. fibers act as impact absorbers for mastication.

Front 15

masticory mucosa

Back 15

comprised of the tissue that covers the hard palate and the gingiva.

Front 16

hard palate

Back 16

covered with masticatory mucosa and firmly adhered to the palatine process. parts:1.incisive papilla,2.palatine raphe,3.palatine rugae

Front 17

gingiva

Back 17

specialized masticory mucosa covering the alveolar process. aids in the support of teeth and protects the alveolar process & periodonal ligament from bacterial invasion.

Front 18

dental caries

Back 18

a lesion starting on the enamel of the tooth and eventually grows into the dentin involving the pulp.

Front 19

acute pulpitis

Back 19

inflammation of the pulp caused by injury to the pulp, usually from dental caries or trauma. MOST FREQUENT CAUSE OF SEVERE TOOTH PAIN.

Front 20

periapical abscess

Back 20

results from an infection of the pulpal tissue causeing the pulp to become necrotic

Front 21

marginal gingivitis

Back 21

inflammation of the gingival tissue

Front 22

necrotizing ulcerative gingivitis

Back 22

severe infiction of the gingival tissue, commonly referred to as TRENCHMOUTH.

Front 23

periodontitis

Back 23

inflammation ofthe gingiva that incolves thec rest of the alveolar bone and the periodontal ligament above the alveolar crest.

Front 24

periodontal abscess

Back 24

caused by an infection of the periodonal tissues.

Front 25

pericoronitis

Back 25

inflammation of the gingiva around a partially erupted tooth.

Front 26

stomatitis

Back 26

inflammation of the oral mucosa.

Front 27

recurrent labial herpes

Back 27

caused by a cirus that produces the so-called fever blister or cold sore.

Front 28

postextraction hemorrhage

Back 28

may occur any time from a few hours to several days after the extraction of the tooth.

Front 29

postextraction alveolar osteitis

Back 29

commonly regerred to as DRY SOCKET. results when a blood clot fails to form or washes of the socket of a recently extracted tooth.

Front 30

type I fracture

Back 30

enamel fracture.a slight chip or fracture of the tooth enamel layer only, or with possible minimal dentin involvement.

Front 31

type II fracture

Back 31

enamel/dentin fracture: extensive fracture involving the enamel and dentin laters, with no pulp exposure

Front 32

type III fracture

Back 32

enamel/dentin fracture with pulp exposure: extensive fracture with the pulp exposed, most or all of the crown is fractured off, bleeding from crown fracture

Front 33

type IV fracture

Back 33

root fracture: a fractured root which may be further complicated by a fracture of the crown, tooth mobility, and other facial trauma associated with the accident.
