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

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

11

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.
