Teeth Flashcards
What is the only soft tissue contained in the tooth?
Pulp
Apical foramen
Located at end of each root → allows passage of vessels and nn. in and out of tooth through root canal
4 osseous structures associated with teeth
- Alveolar process
- Interalveolar septa
- Interradicular septa
- Alveolar juga
Interalveolar septa
Bone between adjacent teeth
Interradicular septa
Bone between roots of same tooth
Alveolar juga
Bony elevation over lateral surface of tooth
What is periodontium?
Supporting tissues of teeth
Periodontium includes?
- Gingivae
- Periodontal lig.
- Cementum
- Alveolar socket
Periodontium contains
- Fibroelastic fibers
- Vessels and nn.
- Specialized cells
Gingivae aka?
Gums
Gingivae are continuous with?
- Alveolar periostium
2. Mucosa of vestibule and floor of oral cavity proper
Gingival margin
Edge of gingiva not attached to crown
Gingival sulcus
Between tooth and gingival margin
Periodontal lig.
Attaches root to alveolar b. via Sharpey’s fibers
Mucogingival junction
Scalloped indistinct line separating gingiva from oral mucosa → parallels free margin of gingiva
Occlusial surface
Contact surface with tooth of opposite jaw
Contact surface
Surface which faces adjacent teeth in same row
Mesial contact surface
Surface toward first incisor (axial)
Distal contact surface
Surface away from first incisor (abaxial)
Lingual surface
Surface which faces tongue
Vestibular surface
Facing lips (labial) or cheeks (buccal)
Dental formula describes?
Number and classification of dentition of species
Dental formula abbreviations representing type of tooth
I = incisor
C = canine
P = premolar
M = molar
Number of dental formula represents?
Particular tooth on one side of upper or lower arcades
Carnassial means?

Eruption times in dog of permanent teeth
Incisors at 4 mo., everything else at 5-7 mo.
Eruption times in cat of deciduous teeth
Incisors at 2-3 weeks, followed by canines (3-4 weeks) and premolars (3-6 weeks)
Eruption times in cat of permanent teeth
