title: Unusual root development following surgical repositioning of horizontally developing central incisor.
abstract: Dilaceration is one of the causes of maxillary central incisor eruption failure. If the dilacerated maxillary permanent central incisor is in a horizontal or vertical position and root formation is in early stages, surgical repositioning is frequently the treatment of choice. In this article, the case of a horizontally impacted and dilacerated maxillary central incisor is presented which was treated by surgical repositioning. The tooth developed an unusual form of the root with discontinuity at the middle third region with the coronal and apical parts growing separately. Radiographic and clinical monitoring of the case was regularly performed. The tooth completely erupted in 2 years after the repositioning and even after 6 years of surgery is currently successfully functional in the arch with the malformed root. This article highlights the ability of Hertwig's epithelial root sheath to withstand trauma and its ability to recover.
