Variations in the dental anatomy are found in all teeth. Understanding root canal morphology is one of the most important steps in successful root canal treatment. Thus, during the diagnosis and treatment phases of maxillary molars, a clinician must be aware that anatomical variations exist. The purpose of this study is to present a clinical case of a maxillary first molar having three mesiobuc...

Thorough understanding of the anatomic and internal morphology of a root canal system is absolutely essential for the success of endodontic treatment. Since permanent maxillary first molars have shown variation in internal anatomy, morphology, this tooth has been reviewed extensively. Presence of two canals in a two-rooted maxillary first molar has rarely been reported in studies describing too...

A major anatomical variant of the two-rooted mandibular first molar is a tooth with an additional distolingual third root: The radix entomolaris (RE). It is essential to anticipate and find all roots and canals during root canal treatment. Proper angulations and interpretation of radiographs help to identify pulp chamber and root anatomy. If present, an awareness and understanding of this unusu...
