The mesial side of the crown is often longer than the distal side, causing the incisai ridge.Although the crown of the mandibular lateral incisor is somewhat longer than that of the central incisor (usually a fraction of a millimeter).there is no marked difference between the mesial and distal surfaces of central and lateral incisors.There is a tendency toward a deeper concavity immediately above the cervical line on the distal surface of the mandibular lateral incisor.including the developmental depressions mesially and distally.7-19, specimen 1).

The mesial side of the crown is often longer than the distal side, causing the incisai ridge. which is straight, to slope downward in a distal direction (Fig. 7-19, specimen 1). The distal contact area is more toward the cervical than the mesial contact area to contact properly the mesial contact area of the mandibular canine.
Except for size. there is no marked difference between the mesial and distal surfaces of central and lateral incisors. Even the curvatures of the cervical line mesially and distally are similar in extent. There is a tendency toward a deeper concavity immediately above the cervical line on the distal surface of the mandibular lateral incisor.
Although the crown of the mandibular lateral incisor is somewhat longer than that of the central incisor (usually a fraction of a millimeter). the root may be considerably longer. The tooth is, therefore. in most instances, a little larger in all dimensions. The root form is similar to that of the central incisor. including the developmental depressions mesially and distally.
