Background: Knowledge on the root canal system morphology of maxillary molars is an essential prerequisite for the success of root canal therapy. The aim of this article is to present endodontic management of three maxillary first molars with unusual root canal system morphologies. The most common form of maxillary first molar has three roots and four canals, but variations are always present.
Methods: This case report presents one case of single unilateral mesotaurodont maxillary first molar in a healthy person, which is reported for the first time. The second case is a maxillary first molar with two canals in a single root as one of the rarest variations of maxillary first molars, and a maxillary first molar is presented with two roots and two canals. Results: This article extends the range of known possible anatomical variations to include teeth with fewer roots and canals. Conclusion: Clinicians must have proper knowledge on root canal morphology and the possible variations.
Keywords: Anatomic variation, case report, maxillary first molar, root canal treatment.
