What is the crown of the tooth?
|
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.
|
|
What is the root of the tooth?
|
The root of the tooth is embedded in alveolar bone and is covered by cementum.
|
|
What is the cervix of the tooth?
|
Slight indentation that encircles the tooth and marks the junction of the crown with the root.
|
|
What is the term for a tooth with two roots?-three roots?
|
bifurcated- trifurcated
|
|
Cementum
|
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.
|
|
The dental pulp
|
soft tissue of the tooth which develops from the connective tissue of the dental papilla.
|
|
The alveolar process
|
bony portion of the maxilla and mandable where the teeth are embedded and by which tooth roots are supported
|
|
Periodontium
|
the tissues that surround and support the teeth. thier main purpose is to support, protect, and provide nurishment for the teeth.
|
|
cortical plate (portion of alveolar process)
|
the cortical plate is composed of ligual and facial plates of compact bone.provides strength and protection and acts as attachment for skeletal muscles.
|
|
alveolar crest
|
highest point of the alveolar ridge and joins the facial and lingual cortical plates.
|
|
trabecular bone
|
trabecular or spongy bone lies within the central portion of the alveolar process and is the less dense canellous bone.
|
|
alveolar bone proper
|
thin layer of compact bone that is a specialized continuation of the cortical plate & forms the tooth socket
|
|
cementum
|
the only tissue considered as both part of the tooth and the periodontium.functions as an area of attachment for the periodontal ligament fibers.
|
|
periodontal ligaments
|
thin, fibrous ligament that connects the bone to the socket. fibers act as impact absorbers for mastication.
|
|
masticory mucosa
|
comprised of the tissue that covers the hard palate and the gingiva.
|
|
hard palate
|
covered with masticatory mucosa and firmly adhered to the palatine process. parts:1.incisive papilla,2.palatine raphe,3.palatine rugae
|
|
gingiva
|
specialized masticory mucosa covering the alveolar process. aids in the support of teeth and protects the alveolar process & periodonal ligament from bacterial invasion.
|
|
dental caries
|
a lesion starting on the enamel of the tooth and eventually grows into the dentin involving the pulp.
|
|
acute pulpitis
|
inflammation of the pulp caused by injury to the pulp, usually from dental caries or trauma. MOST FREQUENT CAUSE OF SEVERE TOOTH PAIN.
|
|
periapical abscess
|
results from an infection of the pulpal tissue causeing the pulp to become necrotic
|
|
marginal gingivitis
|
inflammation of the gingival tissue
|
|
necrotizing ulcerative gingivitis
|
severe infiction of the gingival tissue, commonly referred to as TRENCHMOUTH.
|
|
periodontitis
|
inflammation ofthe gingiva that incolves thec rest of the alveolar bone and the periodontal ligament above the alveolar crest.
|
|
periodontal abscess
|
caused by an infection of the periodonal tissues.
|
|
pericoronitis
|
inflammation of the gingiva around a partially erupted tooth.
|
|
stomatitis
|
inflammation of the oral mucosa.
|
|
recurrent labial herpes
|
caused by a cirus that produces the so-called fever blister or cold sore.
|
|
postextraction hemorrhage
|
may occur any time from a few hours to several days after the extraction of the tooth.
|
|
postextraction alveolar osteitis
|
commonly regerred to as DRY SOCKET. results when a blood clot fails to form or washes of the socket of a recently extracted tooth.
|
|
type I fracture
|
enamel fracture.a slight chip or fracture of the tooth enamel layer only, or with possible minimal dentin involvement.
|
|
type II fracture
|
enamel/dentin fracture: extensive fracture involving the enamel and dentin laters, with no pulp exposure
|
|
type III fracture
|
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
|
|
type IV fracture
|
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.
