ABSTRACT

Aim: To present a case of a mandibular first molar with an additional distolingual root [radix entomolaris (RE)]. Summary: A 20-year-old male individual was referred for root canal treatment of the right mandibular first molar (tooth 46) and left mandibular first molar (tooth 36). After clinical and radiographic examination, symptomatic irreversible pulpitis was diagnosed. Three periapical radiographs with different horizontal angulations revealed the presence of an additional distolingual root. This extra root, termed Radix Entomolaris. The prevalence of these three-rooted mandibular first molars appears to be less than 3% in African populations, not to exceed 4.2% in Caucasians, to be less than 5% in Eurasian and Asian populations, and to be higher than 5% (even up to 40%) in populations with Mongolian traits. The conventional access opening was done, and four root canals were found. All canals were instrumented with new nickel–titanium (NiTi) files to reduce the risk of fractured instruments. After preparation, the root canals were filled using cold lateral condensation techniques.
