what is the geometric outline for the facial and lingual view of the max. left canine?
shows more curvature toward the cusp tip than that of distal
the labiolingual surface is significantly more thick than any other anterior teeth

root surface shows a slight indentation or depression extending from the cervical line halfway toward the apex of the root
On the mesial surfaces of a max. right canine, explain the structure of the surface.

what is the location for the incisal and proximal cusp tip?
mandibular right canine
identify this tooth (which arch is this tooth located)

what is special about the occlusion of maxillary canine
class l occlusion
the maxillary canine lies in the embrasure between the mandibular canine and first premolar
the most common occlusion (70% of the population)
