A 67-year-old male patient was referred for further treatment of a mandibular left first premolar. The tooth presented with slight percussion tenderness and the periodontal probing depth was normal. There was no soft tissue swelling. The radiographic image exhibited a temporary restoration in the previously initiated access cavity of the mandibular left first premolar. The diagnosis of the mandibular left first premolar was previously initiated therapy associated with symptomatic apical periodontitis. The tooth presented four root canals and the characteristics of taurodontism. Two buccal root canals bifurcated at the apical third. The pulpal floor was examined under a dental operating microscope and four canal orifices were identified. TruNatomy Glider was used for glide path preparation. TruNatomy Prime file was selected for final root canal preparation in order to maximally preserve the radicular dentin. Root canal irrigation was achieved by using RC-Prep and 2.5% NaOCl between each file application. Canal blockage was avoided by multiple recapitulations with K-files (#10) between changing each rotary file. Obturation of the canals were performed by using TruNatomy Conform Fit® Gutta-Percha cones and AH Plus® root canal sealer via the warm lateral condensation technique. CBCT was arranged for confirmation after root canal treatment of the mandibular left first premolar and showed a good outcome. The clinical procedures and instruments could provide the practitioners for reference while managing such a difficult case.
