QuestionAnswer
system developed by Dr. Edward H. Angle to describe and classify occlusion and malocclusion Angle's Classification
toward the front Anterior
division of the root nearest the tip of the root Apical third
tooth surface closest to the inner cheek Buccal surface
lenthwise division of the crown in a labial or buccolingual direction, consisting of the facial or buccal/labial third, middle third, and lingual third. Buccolingual division
maximum contact between the occluding surfaces of the maxillary and mandibular teeth centric occlusion
division of the root nearest the neck of the tooth cervical third
curved inward concave
area of the mesial or distal surface of a tooth that touches the adjacent tooth in the same arch contact area
curved outward convex
curvature formed by the maxillary and mandibular arches in occlusion Curve of Spee
cross-arch curvature of the occlusal plane Curve of Wilson
pertaining to first dentition of 20 teeth; often called "baby teeth" or primary teeth. Deciduous
natural teeth in the dental arch dentition
surface of tooth distant from the midline distal
a class II malocclusion in which the mesiobuccal cusp of the maxillary first molar occludes (by more than the width of a premolar) mesial to the mesiobuccal groove of the mandibular first molar Distoclusion
triangular space in a gingival direction between the proximal surfaces of two adjoining teeth in contact Embrasure
tooth surface closest to the face.facial surfaces closest to the lips are called labial surfaces, & facial surfaces closest to the inner cheek are called buccal surfaces; therefore, the term facial can be substituted for labial and buccal, and vice versa facial surface
contact of the teeth during biting and chewing movements functional occlusion
chewing surface of anterior teeth incisal surface
the area between adjacent tooth surfaces interproximal space
facial surface closest to the lips labial surface
inclination of the teeth to extend facially beyond the normal overlap of the incisal edge of the maxillary incisors over the mandibular incisors labioversion
junction of two walls in a cavity preparation line angle
surface of mandibular and maxillary teeth closest to the tongue; also called palatal surface lingual surface
position in which the maxillary incisors are behind the mandibular incisors linguoversion
occlusion that is deviated from a class I normal occlusion Malocclusion
the lower jaw Mandibular arch
chewing surface of the teeth Masticatory surface
the upper jaw Maxillary arch
surface of tooth toward the midline mesial surface
term used for class III malocclusion Mesioclusion
lengthwise division of the crown in a mesiodistal (front-to-back) direction, consisting of the mesial third, middle third, and distal third Mesiodistal division
division of the root in the middle middle third
a mixture of permanent teeth and primary teeth that occurs until all primary teeth have been lost, usually between the ages of 6 and 12 Mixed dentition
an ideal mesiodistal relationship between the jaws and the dental arches Neutroclusion
chewing surface of posterior teeth occlusal surface
the natural contact of the maxillary and mandibular teeth in all positions occlusion
crosswise division of the crown that is parallel to the occlusal or incisal surface, consisting of the occlusal third, middle third, and cervical third occlusocervical division
lingual surface of maxillary teeth palatal surface
angle formed by the junction of three surfaces point angle
toward the back posterior
the first set of 20 primary teeth primary dentition
the surfaces next to each other when teeth are adjacent in the arch proximal surfaces
one quarter of the dentition quadrant
one sixth of the dentition sextant
permanent teeth that replace the primary teeth succedaneous
a two-cusp type of mandibular second premolar bicanineate
divided into two bifurcated
area in which two roots divide bifurcation
external vertical bony ridge on the labial surface of the canines canine eminence
most prominent developmental groove on the posterior teeth central groove
raised, rounded area on the cervical third of the lingual surface cingulum
major elevation on the masticatory surfaces of canines and posterior teeth cusp
the fifth supplemental cusp found lingual to the mesiolingual cusp Cusp of Carabelli
a space between two teeth diastema
wide, shallow depression on the lingual surfaces of anterior teeth fossa
area between two or more root branches furcation
slight ridges that run mesiodistally in the cervical third of the teeth imbrication lines
ridge on permanent incisors that appears flattened on labial, lingual, or incisal view after tooth eruption incisal edge
sloping areas between the cusp ridges inclined cuspal planes
rounded enamel extension on the incisal ridges of incisors mamelon
a developmental groove that crosses a marginal ridge and serves as a spillway, allowing food to escape during mastication marginal groove
rounded, raised border on the mesial and distal portions of the lingual surfaces of anterior teeth and the occlusal table of posterior teeth marginal ridge
teeth located in the posterior aspect of the upper and lower jaws molars
study of form and shape, as of the teeth Morphology
pertaining to a permanent tooth that does not replace a primary tooth Nonsuccedaneous
incisors with a pointed or tapered shape pegged laterals
permanent teeth that replace primary teeth succedaneous teeth
a developmental groove that separates a marginal ridge from the triangular ridge of a cusp Triangular groove
a three-cusp type of mandibular second premolar tricanineate
divided into three trifurcated
area in which three roots divide trifurcation
area or process of discovering tooth imperfections or decay detection
outside the oral cavity extraoral
within the oral cavity intraoral
to have movement mobility
branch of biology that deals with form and structure Morphologically, morphologic, morphology
touching or feeling for abnormalities within soft tissue palpation
use of a slender, flexible instrument to explore and measure the periodontal pocket probing
the use of dental material to restore a tooth or teeth to a functional permanent unit restoration
