[Root apex localization of palatally displaced canines].
BACKGROUND
The aim of this study was to investigate the positions of           the root apices of palatally impacted canines with cone beam computed tomography. While it           is true that the position of the crown determines the surgical approach and direction of           traction, the location of the apex also plays an important role in orthodontic mechanics.


METHODS
Twenty-seven unilateral palatally impacted canines were           evaluated on cone beam images. Measurements were taken using Osirix(®)           software, in order to compare the location of the apex of the palatally impacted canine           with the apex of the contro-lateral normally erupted canine.


RESULTS
The           root apex of a palatally impacted canine was usually correctly positioned in the line of           the arch.


CONCLUSIONS
In most cases, the orthodontic management of           palatally impacted canines requires little or no root torquing.
