Dental Anatomy Quiz

The lower jaw, containing lower teeth.

Teeth located in the mandible (lower jaw).

The curved row of teeth in the upper or lower jaw.

An imaginary vertical line dividing the dental arch into equal right and left segments.

One of four sections that the dental arch is divided into.

Anterior teeth used for cutting or biting.

Anterior teeth used for tearing and piercing.

Posterior teeth used for grinding and crushing food.

Posterior teeth used for grinding food.

Teeth at the front of the mouth-incisors and canines.

Teeth at the back of the mouth-premolars and molars.

The first set of teeth, also called deciduous teeth, in a human's life.

The second set of teeth that replace the primary teeth, known as adult teeth.

A shorthand way to represent the number and type of teeth in each quadrant of the mouth.

The first set of teeth; milk teeth; temporary set of teeth.

The permanent adult tooth set that replaces the primary teeth.

A system for numbering teeth, identifying each tooth by its location in the mouth.

A tooth-numbering system that uses two digits to identify each tooth by quadrant.

2-1-2 (incisors-canines-molars) for each side, in each quadrant; 20 teeth total.

2-1-2-3 (incisors-canines-pre-molars- molars) for each side, in each quadrant; 32 teeth total.

The central space within a tooth, containing the pulp, nerves, and blood vessels.

The portion of the tooth that is visible above the gum line.

The portion of the tooth that is exposed, including the anatomical crown and part of the root that is exposed above the gum line.

The portion of the tooth below the gum line.

The portion of the tooth that is below the gum line

The loss of attachment between the gum and the tooth, causing the exposed root.

The hard, outermost layer of a tooth; hardest tissue.

The hard, calcified tissue beneath the enamel.

The hard, calcified tissue covering the root of a tooth.

The soft, specialized connective tissue within the tooth's pulp cavity.

Connective tissue that connects the tooth to the surrounding bone.

The junction between the cementum and the enamel.

The junction between dentin and enamel.

The junction between dentin and cementum.

A linear elevation on the lingual surface of incisors.

The sloping sides of a cusp on lingual surfaces of posterior teeth.

Linear elevation on the lingual surface of canines.

Linear elevations running from cusp tips toward the gum line, one mesial and one distal.

Linear elevations running along the mesial and distal surfaces on occlusal of posterior teeth.

Most molars develop from 4 lobes (2 buccal, 2 lingual). Mandibular first molars are unique as they are formed from 5 lobes.

Some maxillary third molars have only 3 lobes, fewer than the typical pattern.

Ridges that extend from posterior cusp tips and join the central part of the occlusal surface.

Pyramidal projections on occlusal surfaces of premolars and molars, and canine's incisal portion. Cusp slopes (inclined surfaces) meet at a point.

Union of directly opposing triangular ridges.

Bulge on the lingual surface of anterior teeth (incisors & canines) located in the cervical third of those teeth.

Union of non-opposing triangular ridges on buccal & lingual cusps.

Narrow, shallow groove representing the union of primary lobes on occlusal, potentially extending into buccal/lingual.

Small, rounded enamel projections on newly erupted permanent incisors, eventually wearing away.

Small, irregular grooves on occlusal surfaces that DO NOT show primary lobe union .

Small enamel elevation, sometimes found on palatal or lingual surfaces, often due to excess enamel formation.

Small enamel deposits often located on the root surface, particularly in furcation areas of molars.

Fault in enamel at the bottom of developmental grooves.

Linear elevation on tooth surfaces, including facial (buccal/labial), lingual, and occlusal surfaces of posterior teeth.

Broad depression or valley on posterior tooth occlusal surfaces, sloping toward the cusp tips.

Small depression on anterior lingual or posterior occlusal surfaces.

Linear elevation on the labial (front) surface of canines.

A ridge on the buccal (cheek) surface of premolars.

Ridge found in the neck (cervical) area of all teeth, often more prominent in deciduous and some permanent teeth.

A depression on the lingual surface of anterior teeth.

A depression on the occlusal surface of posterior teeth, mesial to the marginal ridges.

A depression on the occlusal surface of posterior teeth, distal to the marginal ridges.

A depression on the occlusal surface of molars formed by converging ridges.

A small depression at the junction of developmental grooves, potentially at the bottom of fossae.

A depression due to incomplete enamel formation, often at the end of buccal or palatal grooves in molars.

The space between adjacent teeth, normally filled by the gingival papilla.

The curvature adjacent to contact areas, forming spillway spaces.

The tip of the root.

The middle part of a tooth, near the cemento-enamel junction, joining the crown and root.

The bony space in the alveolar bone containing the roots of erupted teeth.

The bony space in the alveolar bone containing developing unerupted teeth.
