Abstract

Familiarity with the diversity of root canal systems dictates the parameters that can affect the prognosis of root canal therapy. Variations in root morphology are rather common occurrences in permanent molars, whereas it is relatively rare in deciduous molars. A usual variation exhibited by deciduous molars is the occurrence of extra roots. The incidence of a deciduous first molar being single-rooted is a scarce finding, especially when occurring bilaterally and with normal occlusal anatomy. This article reports such a rare variation and its successful endodontic treatment.

Keywords: single-rooted deciduous molar, endodontic treatment.
