Accessory root formation on a lower medial incisor.
Accessory root formation on a lower medial incisor dating from the eighth century was observed. The accessory root consisted structurally of dentin (corresponding to the root of the tooth) covered with cement but had no radicular canal. It is therefore not a real supernumerary root. Postmortem deformation was excluded by examination of the alveolar bone. It must have been formed at the time of root development, through a lesion of Hertwig's sheath, as a result of a trauma.
