Sem 5: Incisors and Canines Anatomy

Vocabulary flashcards for tooth anatomy, focusing on incisors and canines (maxillary and mandibular).

Maxillary Central Incisor

Shaped like a shovel.

Incisal edge

Almost straight but slightly oblique to the long axis of the crown.

Palatal Surface of Maxillary Central Incisor

Resembles a triangle, concave-convex.

Mesial Surface of Maxillary Central Incisor

Resembles a triangle with a concave base.

Distal Surface of Maxillary Central Incisor

Shorter and narrower than the mesial surface.

Maxillary Lateral Incisor

Similar in shape to the maxillary central incisor, but smaller in the mesio-distal direction; has a more slender crown.

Palatal Surface of Maxillary Lateral Incisor

Concavo-convex, triangular, smaller and narrower.

Maxillary Lateral Incisor

Smaller crown, mesially rounded angle, distal contact close to the central 1/3, root often tapered distally, incisal edge runs in the distal part obliquely to the long axis of the crown.

Maxillary Central Incisor

Larger crown, mesially almost a right angle with the incisal edge, distal contact closer to the incisal edge, lower probability of root deviation to the distal side, incisal edge almost horizontal.

Mandibular Incisors

Smallest teeth in the oral cavity; wedge-shaped or may have a regular shape; smaller, more flattened, narrower, more slender than the maxillary incisors.

Lingual Surface of Mandibular Central Incisor

Resembles a triangle, slightly smaller than the labial surface; slightly concave in 2/3 from the incisal edge, in 1/3 convex at the cervix, tooth cusp, poorly visible marginal ridges.

Mesial Surface of Mandibular Central Incisor

Similar to a triangle with a concave base; straight line in 2/3 from the incisal edge, convex in 1/3 from the neck, greatest curvature in 1/6 from the neck.

Distal Surface of Mandibular Central Incisor

Almost identical to the mesial surface - narrower, shorter.

Mandibular Lateral Incisor

Greatest similarity of proportions, 0.5 mm larger in each dimension.

Maxillary Canine

Larger, more massive than the mandibular canine.

Disto-labial Line

Shorter, more convex than mesio-labially, contact point - 1/3 from the incisal edge.

Mandibular Canine

Slimmer, narrower, longer crown, contact surfaces and ridges on the lingual surface - less convex.
