  • Title: Crown dilaceration of permanent incisors following trauma to their primary predecessors.
    Author: Maragakis MG.
    Journal: J Clin Pediatr Dent; 1995; 20(1):49-52. PubMed ID: 8634196.
    Abstract:
    Crown dilaceration of a permanent tooth constitutes 3% of traumatic injuries to developing teeth. It usually involves the maxillary incisors and less frequently their mandibular counterparts. This report concerns a patient, whose primary mandibular central incisors, following a fall at the age of 14 months, sustained partial avulsion with displacement. The teeth were repositioned by the father, with the aid of a pediatrician, and without the assistance of a dentist. The patient presented at the age of 8 years, and, following clinical and radiographic examination, a diagnosis was made of crown dilaceration with lingual displacement of the incisal third of the permanent mandibular central incisors, and hypoplastic enamel on all but the gingival third of their crowns. In addition to this, a supernumerary tooth was discovered labial to and between the mandibular right permanent central incisor and the mandibular right primary lateral incisor. After a brief review of the literature, the treatment of this patient is described and the restoration of the dilacerated teeth, followed by a discussion on crown dilaceration and issues concerning the restoration of such teeth.
