Hypoplasia of a Permanent Incisor Produced by Primary Incisor Intrusion: A Case Report

Orofacial trauma is common in atheletic children and is a serious orodental and general health problem that may have medical, esthetic and psychological consequences for children and their parents. When the root of the primary tooth is close to the unerupted permanent tooth, primary tooth trauma may result in developmental disturbances in the permanent tooth. In the present study a case report of an unusual case in which injury to the primary dentition resulted in developmental disturbances in the crown and the non eruption of the permanent tooth is presented. Localized malformation of the crown of the permanent maxillary right central incisor and enamel hypoplasia were treated with a light-cured composite resin restoration. The unerupted permanent left central incisor was removed surgically. The study also discusses the management after extraction with removable partial denture.
