From the labial view,the mesial and distal contacts are on two different levels of the tooth,which helps one to distinguish the newly erupted permanent right maxillary canine from the left.The mesial contact with the lateral incisor is at the junction of the incisal and middle thirds.The distal contact with the first premolar is more cervical because it is at the middle third.The distal outline is also shorter from this view than the mesial outline and usually has a depression between the distal contact area and the cementoenamel junction,which helps one to distinguish the right maxillary canine from the left.The mesial cusp slope is shorter than the distal cusp slope when first erupted,which helps one to distinguish the right from the left.
