The developmental
depression in root of canine
Secures anchorage;
Increases the surface area for anchorage ; Prevents rotation / displacement
In the permanent maxillary
canine, mesial and distal lingual fossae are
Separated by lingual ridge
When the permanent
maxillary canine is correctly posed so that long axes of the tooth is in line
of vision, tip of the cusp is
Labial to center of crown
labiolingually. the tip of the canine is mesial to the center mesiodistally
The crown of a permanent
mandibular canine appear longer due to
Narrow crown mesiodistally;
Height of contact area is above cervix; The crown could be longer
The line joining the cusp
tip of the distal margin contact extension are a straight line that is
Mesiodistally in maxillary
& lingually in mandibular canine
The lingual cusp of the
premolars develop from the
Lingual lobe
The predominant function of
first premolar of either arch is
Tearing. The second
premolar’s predominant function is to grind
In a permanent maxillary
first premolar the mesial slope of the buccal slope is
Longer than distal slope.
The mesial slope of the buccal cusp ridge of maxillary 2nd premolar is
shorter than distal slope.
The permanent maxillary
first premolar have
Two cusp and 2 pulp canals
From the buccal aspect of
the permanent maxillary first premolar, the tip of the buccal cusp is distal
to line bisecting the
Buccal surface
