Abstract
Objective: The knowledge of internal tooth anatomy and its variations is essential to perform a successful endodontic treatment. The presence of a supernumerary root in primary teeth is uncommon compared to permanent dentition. This paper aims to report a clinical case of an endodontic management of a primary mandibular three rooted molar. Case Report: A 5-year-old female patient complained about a tumefaction in the mandibular left posterior region. The intraoral examination revealed an active caries lesion in the primary mandibular left second molar and swelling in the buccal mucosa related to this tooth. The radiographic exam revealed bilateral primary mandibular three-rooted second molar, and the affect one exhibited periapical radiolucency and was submitted to an endodontic treatment, since clinical and radiographic examination suggested a diagnosis of apical periodontitis. After one-year follow-up the tooth was asymptomatic and the radiographic examination showed a total healing of the periapical lesion. Conclusion: A proper diagnosis, based on appropriated radiographies, and an adequate endodontic treatment, in an atypical primary tooth is important to preserve it until normal exfoliation period, maintaining the tooth function, and avoiding development defects to the germ of successor permanent.
Highlights
One of the most important targets in endodontic therapy is the complete healing of periapical tissues, this treatment aims to heal the damages originated from pulp and periapical pathology, and the healing is only achieved when clinician watches carefully every step of the treatment

The incidence of a supernumerary root in permanent or primary mandibular molar can be a racial characteristic of South American Indians or Mongoloid populations [3,4]

Relato de Caso: Paciente do sexo feminino, 5 anos de idade, relatou tumefação na região mandibular posterior esquerda, o exame intrabucal revelou lesão de cárie ativa no segundo molar inferior decíduo, e inchaço na região vestibular deste dente. O exame radiográfico mostrou segundos molares decíduos inferiores com três raízes, bilateralmente, e o dente afetado revelou área periapical radiolúcida e foi submetido ao tratamento endodôntico, visto que sinais clínicos e radiográficos indicavam periodontite apical.
