Hypoplasia of a permanent incisor produced by primary incisor intrusion: a case report

J Can Dent Assoc. 2009 Apr;75(3):215-8.

Abstract

Orofacial trauma 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 and pulpal reaction in that permanent tooth. We report an unusual case in which injury to the primary dentition resulted in developmental disturbances in the crown and the calcified structures in the pulp chamber of the permanent tooth. Localized malformation of the crown and enamel hypoplasia were treated with a light-cured composite resin restoration. We also discuss the formation of pulp calcification and the need for endodontic treatment.
