Abella F, Mercad M, Duran Sindreu F, Roig M. Managing severe curvature of radix entomolaris: three dimensional analysis with cone beam computed tomography. International Endodontic Journal.Abstract Aim‚ To present a case of a mandibular first molar with an additional distolingual root [radix entomolaris (RE)] and to discuss the use of cone beam computed tomography (CBCT) for its identification and management during root canal treatment.
Summary‚ A 52 year old Caucasian woman was referred for root canal treatment of the right mandibular first molar (tooth 46). After clinical and radiographic examination, a symptomatic irreversible pulpitis was diagnosed. Three periapical radiographs with different horizontal angulations revealed the presence of an additional distolingual root.
