Single-rooted primary first molars.

ABSTRACT

Knowledge regarding the morphological variations in roots and root canals aids in successful dental treatment. However, literature regarding dysmorphology of roots in primary dentition is sparse. The purpose of this article is to present a case of bilateral primary mandibular first molars with an unusual morphology of single root. Review of literature regarding variations in root number in primary dentition has been discussed in this article. The etiology for occurrence of such variations has also been briefly reviewed.
