Mandibular premolars are usually thought to
be easy to treat endodontically but variations in their
anatomic configuration make them a difficult task to
accomplish. The possibility of additional root canals
should always be kept in mind when performing
endodontic treatment with such cases. Adequate
knowledge of pulp canal anatomy, proper radiographic
interpretation, incorporation of CBCT, and dental
operating microscope are prerequisites for the best
possible outcome in complex root canal treatment. This
case series presents a relatively uncommon clinical case of
mandibular premolars with two and three canal
configurations managed with the help of DOM.
