Dental Anatomy: Incisors and Canines

These flashcards cover important vocabulary related to dental anatomy, specifically focusing on incisors and canines, and their distinguishing features.

Class Trait

Used to differentiate a type of tooth from all other teeth.

Type Trait

Differentiating one tooth from the other.

Arch Trait

Distinguishes between maxillary (mx) and mandibular (md) teeth.

Incisors

Teeth characterized by a flattened labio-lingual surface providing a long horizontal biting edge.

Mamelons

The distinct and rounded protuberances that surmount the incisal margins of newly erupted incisors.

Maxillary Incisors

Wider than their mandibular counterparts, with prominent marginal ridges and a deeper lingual fossa.

Mandibular Incisors

The narrowest teeth in the incisor class, with less prominent marginal ridges and a flat labial surface.

Crown

The visible part of the tooth above the gum line, characterized by distinct features in different types of teeth.

Lingual Aspect

Refers to the surface of a tooth that is closest to the tongue.

Facial Aspect

The surface of a tooth that is closest to the face.

Mesial Aspect

The surface of a tooth that is closest to the midline of the dental arch.

Distal Aspect

The surface of a tooth that is farthest from the midline of the dental arch.

Canine

A tooth characterized by a single conical cusp, which plays a role in supporting and anchoring other teeth.

Maxillary Canines

Canines that are larger than mandibular canines and have more pronounced anatomy.

Mandibular Canines

Smaller than maxillary canines, with a flatter surface and less pronounced features.

Labial Surface

The outer surface of the anterior teeth facing the lips.

Lingual Surface

The inner surface of the anterior teeth facing the tongue.

Cingulum

A raised convexity found on the lingual surface of anterior teeth.

Developmental Groove

A groove on the surface of a tooth that marks the fusion lines of the lobes.
