The mesial view of this tooth considers the portion of the tooth visible from the side closest to where the middle line of the face would be.the mesial exis should be parallel to the midline. 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.[15] The root appears cone shaped with a blunt apex. Unlike most other teeth, a line drawn through the center of the incisal edge will also cross through the center of the root apex.[19] This also occurs in maxillary lateral incisors.
