Retreatment of mandibular canine with two roots: a case report

The successful outcome of the endodontic therapy requires an adequate knowledge in context to anatomy of the root canal system. In most cases, the mandibular canines are thought to have just one root canal. Those presenting with an extra root and canal are usually rare, ranging from 1% to 5%. Thus, in spite of this low prevalence, variations in the anatomy and number of root canals in mandibular canines should always be taken into account. This paper presents a case of a mandibular canine with two distinct and separate root canals.
