Endodontic Treatment of C-Shaped Mandibular and Maxillary First Molar Teeth: Report of Two Cases

Abstract

The 'C' configuration of the root canal system is regarded as one of the most important morphologic variations of dentiton. Thus, correct diagnosis and identification of the C-shaped root canal before treatment is an essential step. This aberrant morphology is most frequently found in mandibular second molar although it could be found in the mandibular first molar and the maxillary first molar. The aim of this case report is to present the endodontic intervention of C-shaped canals in mandibular and maxillary first molar teeth and to discuss the morphologic features of fused roots.
