Sequelae in permanent teeth after traumatic injuries to primary dentition

Traumatic injuries to the primary dentition are critical events in dentistry not only due to the need for urgent care, but also since they have potential sequelae in the permanent dentition, with a prevalence ranging from 12% to 74%. The aim of this article was to provide an overview of the prevalence, etiology, and clinical and radiographic characteristics as well as the management of permanent teeth sequelae resulting from traumatic injuries to their deciduous predecessors. An extensive literature review was performed to reveal the current evidence on enamel discoloration with or without hypomineralization/hypoplasia, crown dilaceration, odontoma-like malformation, root anomalies, partial or complete arrest of root formation, sequestration of the permanent tooth germ, and eruption disturbances.
