Is there any case with a mandible premolar tooth with distal and mesial canals? I have a problem with finding the canals of the mentioned tooth. Can anyone help me?
Yes it is possible for the mandibular second premolar to have two roots canals or even at times three canals! Here is a case of the same. According to Grossman, in 2.5% cases a single canal may bifurcate existing in two foramina. Hence it is recommended to take a Cone Beam Computer Tomography and use an apex locator to eliminate confusions.
