The parmmanent maxillary canine is located third in each maxillary quardrant
The canine shear a mesial contact with maxillary LATERAL INCISOR and contacts the maxillary first premolar on the on the distal.

Maxillary CanineLabial aspect The crown of maxillary canine is narrower
mesiodistally than that of maxillary central incisor.
The incisal aspect has a large cusp with a pointed cusp tip
It has two slopes (cusp ridges), the mesial slope being shorter than the distal slope
The labial surface is smooth and bulky in the middle because of the labial ridge

6
Lingual aspect
The crown and root are narrower lingually
The cingulum is well developed, large and sometimes pointed like a cusp
Occasionally a well developed lingual ridge is seen that divides the lingual fossa into mesial and distal lingual fossae
Heavy marginal ridges are associated with well formed cingulum and fossae

Mesial aspect
From the mesial aspect canine looks similar but bulkier than maxillary central incisor
Maxillary canine is the widest anterior tooth labiolingually
The cervical line curvature is towards the cusp (incisally)
The contact area is near the junction of the incisal and middle third

Distal aspect Distal surface is very similar to the mesial surface The cervical line exhibits less curvature The contact are is near the middle third
Distal aspect

12
Incisal aspect
The labiolingual dimension is greater than the mesiodistal dimension
The cusp tip is labial to the centre of the crown labiolingually and mesial to the centre mesiodistally
The labial ridge and the cingulum are very noticeable from this aspect
Incisal aspect

Root – only oneThe root is the longest and strongest of all the teeth
in the dentition
The mesial and distal surfaces of the root have
developmental depressions.
