A Mandibular Second Premolar with Three Separate Canals - Radiographic and CBCT Observation-A Case Report

The knowledge of complex root canal morphology gives the opportunity to treat the cases with rare anatomy configurations. Incomplete cleaning and shaping of these complicated areas may leave tissue, bacteria, or necrotic debris in the canal. The importance of adequate preparation and three-dimensional obturation is of a great importance for periapical tissue health. This case report describe a radiographic and cone beam computed tomography (CBCT) observation of a second mandibular premolar with one root and three separate canals, with three separate apical foramina (VIII type according the Vertuccis classification).
