Abstract
The mandibular first molar typically exhibits two roots and three canals, but anatomical variations such as the presence of an additional distolingual root known as Radix Entomolaris (RE) which can complicate endodontic treatment. This case report describes the diagnosis and endodontic management of a mandibular first molar with RE in a 24-year-old female patient who presented with symptomatic apical periodontitis. Careful clinical and radiographic examination, including angled radiographs, facilitated the identification of the additional root. A modified access cavity was prepared, and all canals were located, shaped using rotary file system, and obturated successfully. The presence of RE demands precise diagnosis, modification of access design, and meticulous instrumentation to ensure complete debridement and avoid iatrogenic damage.
