Case 5

Lateral canals can occur in the middle of the root as well

lesion.

It can be seen from previous cases that most lateral canals exist at the apical third
#
of the root, however, here, the pre-operative radiograph of tooth 24 revealed not only a
complex root canal system at the apical portion, but also a radiolucent lesion distal

mid-root (Fig 5A). In these cases, the dentist will need to give extra consideration not
only to the apical portion, but also this lateral canal that possibly exists at distal mid-root
(Fig 5B). Patients should be informed of the possible complex lateral canal system, and
special attention should be made to disinfect the entire canal system by utilizing
ultrasonic irrigation.
