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
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
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
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
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.
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.
inflammation of the gingiva around a partially erupted tooth.
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.
