Endodontic Management of a Mandibular Central Incisor with Type IV Canal Pattern: A Case Report.

The success of endodontic treatment requires the knowledge of tooth morphology and its variations. Mandibular incisor's anatomy presents a challenge when an endodontic access is made, because of its small size and high prevalence of two canals. We are describing a Weine's Type IV root canal configuration that was detected in a mandibular central incisor, which was demonstrated by a radiographic examination. This article also focuses on the successful endodontic treatment of a mandibular central incisor with a single canal at the pulp chamber, which divided into two distinct and separate canals (buccolingual) at the middle third of the root.
