Abstract
Morphogically the mandibular second premolars present one root canal (97.5%). So far only a small percentage (2.5%) of cases were reported to have two root canals where they present the canals on the buccal and lingual direction of the root. Here an unusual case of two root canals, which are situated in mesial and distal direction is presented.
