However, variations in this morphology, such as multiple root canals, may occur. A 20-year-old male patient presented with a chief complaint of pain and swelling in the left mandibular region. Based on clinical and radiographic exams, the diagnosis of symptomatic apical periodontitis was established. Initially, two root canals in the mesial root and two in the distal root of tooth #36 were located and negotiated using a dental operating microscope. After further exploration, two more root canals were located in the mesial root. The six root canals were prepared. For the final rinse, the irrigant solutions were agitated with an ultrasonic tip. Calcium hydroxide dressing was used, and one month later, the patient presented without signs or symptoms. The root canal filling was performed using the single-cone technique with gutta-percha cones and bioceramic endodontic sealer. At the 12-month follow-up, a periapical radiograph showed bone repair in the periradicular region. Four root canals in the mesial root of the mandibular first molar represent a rare configuration. The clinician must consider possible anatomical variations of the root canal system and carefully analyze the imaging exams along with clinical observation during treatment so that all canals are located and treated to achieve success.]]></p></abstract>
<abstract abstract-type="short" xml:lang="pt"><p><![CDATA[Resumo O primeiro molar inferior geralmente apresenta uma raiz mesial com dois canais radiculares e uma raiz distal com um ou dois canais radiculares. No entanto, podem ocorrer variações nessa morfologia, como a presença de múltiplos canais radiculares. Um paciente do sexo masculino, de 20 anos, apresentou-se com uma queixa principal de dor e edema na região mandibular esquerda. Com base em exames clínicos e radiográficos, foi estabelecido o diagnóstico de periodontite apical sintomática. Inicialmente, dois canais radiculares na raiz mesial e dois na raiz distal do dente #36 foram localizados e negociados sob um microscópio operatório. Após exploração adicional, mais dois canais radiculares foram localizados na raiz mesial. Os seis canais radiculares foram preparados e, para a irrigação final, as soluções irrigadoras foram agitadas utilizando um instrumento ultrassónico. Foi feito um curativo com pasta de hidróxido de cálcio e, um mês depois, o paciente apresentou-se sem sinais ou sintomas. A obturação do canal radicular foi realizada utilizando a técnica de cone único, com cones de guta-percha e cimento endodôntico biocerâmico. Passados 12 meses, foi feita uma radiografia periapical, que mostrou reparo ósseo na região perirradicular. A presença de quatro canais radiculares na raiz mesial do primeiro molar inferior é uma configuração rara. Possíveis variações anatómicas no sistema de canais radiculares devem ser consideradas pelo profissional, que deve analisar criteriosamente os exames de imagem, além da observação clínica durante o tratamento, para que todos os canais sejam localizados e tratados para alcançar o sucesso.]]></p></abstract>
