Dentition Flashcards
Teeth information
age, sex, health, diet, social structure, and tool use
Anterior teeth
incisors and canines
Posterior teeth
Also called cheek teeth, premolars and molars
Facial
towards the face (incorporates both labial and buccal)
Incisal
cutting surface of the anterior teeth
Occlusal
Chewing surface of the posterior teeth
Interproximal surface
contacts adjacent teeth
Lingual
towards the tongue
Crown
part of the tooth covered by enamel
Root
Anchors the tooth in the socket of the mandible or maxilla
Cervix
Junction of the crown and the root
Enamel
Hard tissue that covers the crown
Dentin
Tissue that corms the core of the tooth, underlies the enamel, surrounds pulp cavity
Pulp
Soft tissue in pulp cavity, contains nerves and blood vessels
Cusp
Occlusal Projection of the crown, useful in identifying teeth
Calculus
Calcified deposit found on tooth crowns, develops from plaque
Tooth Joint
Fibrous joint, specifically a gomphosis. Teeth are anchored into the socket with periodontal ligaments. Allows little movement
Deciduous teeth
The first set of teeth to form, erupt, and function in humans. Thinner enamel on crowns, and more bulbous in shape, with thinner roots.
Human dental formula
2.1.2.3
Incisors
flat, blade-like crowns. Rectangular cross section
Canines
Conical crowns, oval or diamond shaped cross-section, relatively long root
Premolars
rounded crowns, shorter than canines, smaller than molars. Usually 2 cusps and a single root
Molars
large, square crowns with more than two cusps, and usually multiple roots.
Upper and Lower Incisors and Canines
Upper crowns are relatively broad, and lower crowns are narrow
Upper and Lower Premolars
Upper cusps nearly equal in size, while there is more disparity in cusp size in lower cusps
Upper Molars
Typically 3-4 major cusps, rhombus in shape. with 3 major roots.
