Angle's classification   System developed by Dr. Edward H. ANGLE to describe and classify occlusion and malocclusion.  
Anterior   Toward the FRONT  
Apical third   Division of the root nearest the tip of the root  
Buccal Surface   Tooth surface closest to the inner cheek  
Buccolingual division   Lengthwise division of the crown in a labial or BUCCALINGUAL direction, consisting of the facial or buccal/labial third, middle third , and lingual third.  
Centric occlusion   Maximum contact between the occluding surfaces of the maxillary and mandibular teeth  
Concave   Curved INWARD  
Curve of Spee   CURVATURE formed by the maxillary and mandibular arches in occlusion  
Curve of Wilson   Cross-arch curvature of occlusal plane  
Convex   Curved OUTWARD  
Contact area   Area of the MESIAL or DISTAL surface of a tooth that TOUCHES the adjacent tooth in the same arch.  
Deciduous   Pertaining to first dentition of 20 teeth, often called "BABY TEETH" or primary teeth  
Dentition   NATURAL teeth in the dental arch  
Distal surface   Surface of tooth DISTANT from the midline  
Distoclusion   A class II malocclusion in which the mesibuccal 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.  
Embrasure   TRIANGULAR space in a gingival direction between the proximal surfaces of two adjoining teeth in contact  
Facial surface   Tooth surface closest to the face. Facial surfaces closest to the lips are called labial surfaces, and facial surfaces clostest to the inner cheek are called buccal surfaces; therefore, the term facial can be substituted for labial and buccal andVICEVERSA  
Functional occlusion   Contact of the teeth during BITING and CHEWING movements  
Incisal surface   CHEWING SURFACE of ANTERIOR teeth  
Interproximal space   The AREA BETWEEN adjacent tooth surfaces  
Labial surface   Facial surface CLOSEST TO THE LIPS  
Labioversion   The inclination of the teeth that extent facially beyond the normal OVERLAP of the incisal edge of the maxillary incisors over the mandibular incisors.  
Line angle   JUNCTION of two walls in a cavity preparation  
Lingual surface   SURFACE of mandibular and maxillary teeth closest to the tongue; also called PALATAL SURFACE  
Linguoversion   Position in which the maxillary incisors are behind the mandubular incisors  
Maloccusion   OCCLUSION that is DEVIATED from a class I normal occlusion  
Mandibular arch   The LOWER JAW  
Masticatory surface   The CHEWING SURFACE of the teeth  
Maxillary arch   UPPER JAW  
Mesial Surface   Surface of the tooth toward the MIDLINE  
Mesioclusion   Term used for CLASS III malocclusion  
Mesiodistal division   Lengthwise division of the crown in a MESIODISTAL (FRONT-TO-BACK) direction, consisting of the mesial third, middle third, and distal third  
Middle third   Division of the root in the MIDDLE  
Mixed dentition   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  
Neutroclusion   An ideal mesiodistal relationship between the JAWS and the dental ARCHES  
Occlusal surface   CHEWING SURFACE of POSTERIOR teeth  
Occlusion   The natural contact of the maxillary and mandibular teeth in all positions  
Occlusocervical division   CROSSWISE division of the crown that is parallel to the occlusal or incisal surface; consisting of the occlusal third, middle third, and cervical third  
Palatal Surface   LINGUAL surface of MAXILLARY teeth  
Point angle   ANGLE formed by the junction of THREE SURFACES  
Posterior   TOWARD the BACK  
Primary dentition   The first set of 20 PRIMARY teeth  
Proximal surfaces   The surfaces NEXT TO EACH OTHER when teeth are adjacent in the arch  
Quadrant   One QUARTER of the dentition  
Sextant   One SIXTH of the dentition  
Succedaneous   Permanent teeth that REPLACE primary teeth  
Bicanineate   A TWO-CUSP type of mandubular second premolar  
Bifurcated   Divided in TWO  
Bifurcation   Arean in which TWO ROOTS divide  
Canine eminence   External VERTICAL BONY RIDGE on the libial surface of the CANINES  
Central groove   Most prominent developmental GROOVE on the POSTERIOR TEETH  
Cingulum   RAISED, ROUNDED area on the cervical third of the lingual surface  
Cusp   Major elevation on the MASTICATORY surfaces of canines and posterior teeth  
Cusp of Carabelli   The FIFTH supplemental CUSP found lingual to the mesiolingual cusp  
Diastema   A space between two teeth  
Fossa   WIDE, shallow depression on the lingual surfaces of anterior teeth  
Furcation   Area between TWO OR MORE ROOT branches  
Imbrincation   SLIGHT RIDGES that run mesiodistally in the cervical third of the teeth  
Incisal edge   RIDGE on permanent incisors that appears flattened on labial, lingual, or INCISAL view after tooth eruption  
Inclined cuspal planes   SLOPING AREAS between the cusp ridges  
Mamelon   ROUNDED ENAMEL extension on the incisal ridges of incisors  
Marginal groove   A developmental groove that CROSSES a marginal ridge and serves as a SPILLWAY, allowing food to escape during masticaion  
Marginal ridge   ROUNDED, RAISED border on teh mesial and distal portions of the lingual surfaces of anterior teeth and the occlusal table of posterior teeth  
Molars   Teeth located in the posterior aspect of the upper and lower jaws  
Morphology   STUDY of form and shape, as of the teeth  
Nonsuccedaneous   Pertaining to a permanent tooth that DOES NOT REPLACE a primary tooth  
Pegged laterals   Incisors with a POINTED or TAPERED shape  
Trianglers grooves   A developmental groove that separates a marginal ridge from the TRIANGULAR RIDGE OF A CUSP  
Tricanineate   A THREE-CUSP type of mandibular second premolar  
Trifurcated   DIVIDED INTO THREE  
Trifurcation   Are in which THREE ROOTS DIVIDE  
Detection   Act or process of discovering tooth IMPERFECTIONS of decay  
Extraoral   OUTSIDE the oral cavity  
Furcation   Area between two or more ROOT BRANCHES  
Intaoral   WithIN the oral cavity  
Mobility   To have MOVEMENT  
Morphologically, Morphology   Branch of BIOLOGY that deals with form and structure  
Palpation   Touching or feeling for ABNORMALITIES within soft tissue  
Probing   Use of a SLENDER, FLEXIBLE instrument to explore and measure the periodontal pocket  
Restoration   The use of dental material to RESTORE a tooth or teeth to a function permanent unit  
Symmetric   BALANCED or even on both sides
