The mesial and distal outlines of the deciduous maxillary canine is (concave/convex) to the cervical line
convex
T/F: Similarly to permanent teeth, the DCR>MCR for the deciduous maxillary canine
F: MCR>DCR- similarly to maxillary 1st premolar
The shape of the deciduous maxillary canine from the front is
pentagon
From the lingual the crown of deciduous maxillary canine is
pentagon
T/F: The deciduous maxillary canine doesn’t have a prominent cingulum nor marginal ridges
F: Both Prominent
Mesial contact for deciduous maxillary canine
will be more cervical because of the mesial convexity
Distal contact for deciduous maxillary canine
will be more incisal due to mesial bulge (opposite in permanent dentition- similar to maxillary 1st premolar)
When viewing the deciduous maxillary canine from the incisal view, the Cups tip is placed to the (distal/mesial)
distal
