Abstract
Introduction
The C-shaped configuration is rare in the upper first molar.The purpose of this article
is to present 2 cases diagnosed during endodontic therapy and perform a literature
review of this anatomy in the upper first molar.
Methods
Endodontic therapy was performed by using a dental operating microscope and a cone-beam
computed tomography analysis for better understanding of this anatomy. A literature
search was conducted to identify and compare all the published cases of C-shaped upper
first molar.
Results
Before the cases reported in this article, only 5 cases were available in the published
literature. Three different types of C-shaped configurations in the upper first molar
have been presented.
Conclusions
The C-shaped maxillary first molar is a rare anatomic configuration. The use of the
dental operating microscope may help in the endodontic therapy of these cases. Three
types of C-shaped configurations have been reported; the fusion of the distobuccal
root with the palatal root appears to be the most usual one.
