Three prominences, or scallops, are usually seen along the incisal edge.

Because of the disproportionate incisal edges, the contacts are also asymmetrical.

The lingual incisal edge is also raised slightly to the level of the marginal ridges.

Mammelons are usually found as three small bumps on the incisal edges of anterior teeth.

It is the longest tooth in total length, from root to the incisal edge, in the mouth.

Instead, the surface area of the tooth used in eating is called an incisal ridge or incisal edge.

When this tooth is newly erupted into the mouth, the incisal edges have three rounded features called mammelons.

The center of the incisal edge curves slightly downward in the center of the tooth.

The incisal edges of the mandibular teeth can be smoothed to minimize the chance of trauma.

After the mammelons are worn away, the incisal edge of the maxillary central incisor is straight mesiodistally.

The labial surface of the crown is convex from the crest of curvature to the incisal edge.

Class IV Caries affecting proximal including incisal edges of anterior teeth.

Unlike most other teeth, a line drawn through the center of the incisal edge will also cross through the center of the root apex.

During root canal therapy, access into the pulp is frequently located centrally on the lingual surface between the incisal edge and the cingulum.

Use of the painting method entails coating the incisal edges of a dental model with red glossy paint and then photographing the model.

The incisal view of this tooth considers the portion of the tooth visible from the side where the incisal edge is located.

Use of the 2D polyline method entails drawing straight lines between two fixed points in the arch and between incisal edges to indicate the tooth width.

The contact point of the mandibular teeth is in the lingual fossa of the maxillary central incisor about 4 mm gingivally from the incisal edge.

All incisors have the potential to be affected by a case of congentital syphilis, which can cause a notch to form on the incisal edges of these teeth.

The mesial side of the maxillary central incisor shows the crown of the tooth as a triangle with the point at the incisal edge and the base at the cervix.

The lingual surface of the crown is convex near the cingulum and near the incisal edge, but for the most part is concave along the surface between those two areas.

The lingual fossa is bordered incisally by the lingual incisal edge, mesially by the mesial marginal ridge, distally by the distal marginal ridge, and cervically by the cingulum.

As in the maxillary canine, the mesial incisal edge (or cusp ridge) is shorter than the distal side, however, the cusp is displaced slightly lingual relative to the cusp of the maxillary canine.

E.g. when the canines and incisors of the opposing arches are moved against each other laterally, by the action of the medial pterygoid muscles, this can lead to the wearing down of the incisal edges of the teeth.

Incisally, they are visibly asymmetrical, as the mesial incisal edge is slightly shorter than the distal incisal edge, which places the cusp slightly mesial to the long axis of the tooth.
