Regional Odontodysplasia

Abstract

Odontodysplasia is a rare nonhereditary developmental anomaly of dental hard tissue with unknown etiology, arising from both ectodermal and mesodermal components. Hitchin in 1934 first described it as a localized arrest of tooth development generally affecting one quadrant of the jaw. When it just affects one quadrant, it is referred to as “regional odontodysplasia,” but when it crosses the midline and affects more than one quadrant, it is referred to as “generalised odontodysplasia.” In this two case series, various types of odontodysplasia have been described, one of which is confined to a single quadrant and the other crossing the midline. The cases of odontodysplasia can only be treated by multidisciplinary approach and restorative and prosthetic rehabilitation and regular follow-up require for improving the quality of life of patients.

Regional odontodysplasia involving maxillary right quadrant treated by dental implant prosthetic rehabilitation: A review and case report

“…Radiographically affected teeth have a typical "ghost" appearance [19] . This condition is also referred to as a "shell tooth" to describe radiographic features such as hypoplasia and hypocalcification of enamel and dentin [20] . Affected teeth have large pulp chambers, short roots, and open apices [21] .…”
