Dental Anatomy Terminology Flashcards
Alveolus
The cavity (i.e. socket) in the alveolar process of the maxilla or mandible in which the root of a tooth is secured by the periodontal ligament
Alveolar Bone (or process)
The bony processes of the maxilla or the mandible that contain and support teeth. The main bony tissue of the maxilla and the mandible is called Basal bone
Line Angle
The angle formed by the junction of two tooth surfaces along a line
Point Angle
The angle formed by the junction of three tooth surfaces at a point
Anterior
Situated or placed toward the front of the oral cavity
Anteroposterior
From the front part of the oral cavity to the back
Apex
The terminal end or tip of a root
Apical
Toward the tip/apex of a tooth root
Arch
A structure having curved form like the curved form of the mandibular or maxillary arch
Articulate
The relating of upper and lower natural or artificial teeth to each other
Articulator
A mechanical device that stimulates the temporomandibular joints, the maxilla, and the mandible, and to which dental casts can be attached
Axial
Pertaining to the long axis of a tooth
Axis
A straight line around which a body can rotate
Bicuspid
Premolar
Buccal
Pertaining to or adjacent to the cheek
Canine
One of the four types of human teeth located between the lateral incisors and the first premolars.
The ______ are considered the cornerstones of the dental arch
Caries
The localized, progressive disease process that destroys the calcified, hard tissues of the natural tooth
Cementoenamel junction (CEJ)
The junction of enamel and cementum
Cementum
The hard, calcified tissue covering the root dentin of a tooth
Centric Occlusion
The end point of intercuspation when there is maximal contact and coincidence between upper and lower occlusal surfaces
The intercupsal position is the most closed occlusal position and is know as ________ __________ or maximum intercupsation (MIP)
Centric Relation
The relation of the mandible to the maxilla when the condyles are in the most unrestrained uppermost position in the glenoid fossa irrespective of vertical dimension or tooth position
Cervical
Pertaining to the neck area of a tooth
Cervical Line
A curved line around the neck of a tooth formed by the junction of the enamel and cementum
Cervix
The constricted portion (neck) of a tooth at the junction between the crown and root
Cingulum
The rounded convexity on the lingual side of an anterior tooth
Anatomic Crown
The part of a natural tooth covered by enamel extending from the incisal or occlusal portion of the tooth to the CEJ
Clinical Crown
The part of the tooth that protrudes from the gingival tissues and is visible in the oral cavity
Curve of Spee
The anterioposterior curved line that connects the cusp tips of the posterior teeth; lateral view
Curve of Wilson
The mediolateral curved line that connects the buccal and lingual cusp tips on each side of the arch; frontal view
Cusp Deciduous
A rounded elevation on the occlusal surface of a posterior tooth pertaining to the primary dentition
Dentinoenamel Junction (DEJ)
The junction of enamel and dentin
Dentin
The hard, calcified inter bulk of a natural tooth covered by enamel or cementum
Diastema
A space between two non-contacting adjacent teeth in the same dental arch
Distal
Away from the midline/median line posteriorly along the arch
Edentulous
Without teeth
Embrasure
A “V-shaped” space between two contacting adjacent teeth in the same dental arch.
The four resulting _________ are: Incisal/occlusal, gingival/cervical, facial/labial/buccal, and lingual/palatal
Enamel
The hard, calcified outer portion of a natural tooth covering the anatomic crown
