The most frequently mentioned sequelae in permanent successors include enamel hypoplasia (Carvalho et al., 2010; Altun et al., 2009; Amorim et al., 2011; Gungor et al., 2011), discoloration (Christophersen, Freund, & Harild, 2005; Jacomo & Campos, 2009), deformation of the crown and/or root (Altun et al., 2009; Costa et al., 2016), root dilaceration (Altun et al., 2009), abnormal position (Altun et al., 2009; Costa et al., 2016), prolonged retention (Jacomo & Campos, 2009), eruption disturbances (Altun et al., 2009; Jacomo & Campos, 2009), among others.

These can result into clinical problems like midline diastema; crowding; malocclusion due to insufficient space; dilaceration, delayed, or failure of eruption of permanent teeth; root resorption of adjacent teeth; cyst formation; cheek bite; periodontal problems; dental caries, and other difficulties related to ectopic position.
On the other hand, they may also cause crowding, failure of eruption, diastema, root resorption, dilaceration and displacement of adjacent teeth (1, 2, 6).
Anomalies such as dens invaginatus (0.03%), dentinogenesis imperfecta (0.02%) and dilaceration (0.02%) were encountered more rarely.
Dilaceration is defined as an angulation or sharp bend or curve in the linear relationship of the crown of a tooth to its root.
This report aims to present a successful root canal treatment of a maxillary lateral incisor with unusual palatal root dilaceration (diagnosed with cone beam computed tomography) in which the access cavity was prepared from the labial aspect of the tooth to provide a straight line access to the root canal system which was instrumented using OneC...
Various genetic factors, an exchange in the position of the forming dental lamina along with trauma to the deciduous tooth with the permanent incisor root dilaceration, were suggested as reasons for transposition.
