Endodontically managed mandibular second molars with a single root and root canal: A case report

The variability of root canal system morphology of multirooted teeth represents a challenge to endodontic diagnosis and therapeutics. Variations of root canal systems need not only be in the form of extra canals. Clinicians should be aware that there is also a possibility of existence of lesser number of roots and root canals than the normal root canal anatomy. The aim of this article is to present the case of endodontically managed mandibular second molars with a single root and root canal.
