  • Title: Pulp canal obliteration in an unerupted permanent incisor following trauma to its primary predecessor: a case report.
    Author: Katz-Sagi H, Moskovitz M, Moshonov J, Holan G.
    Journal: Dent Traumatol; 2004 Jun; 20(3):181-3. PubMed ID: 15144452.
    Abstract:
    Trauma to a primary tooth may result in damage to the underlying developing permanent tooth bud because of the close proximity between the root of the primary tooth and its permanent successor. We report an unusual case where injury to the primary dentition resulted in pulp canal obliteration (PCO) of a permanent maxillary central incisor prior to its eruption. The other permanent maxillary central incisor was diagnosed as malformed because of trauma to the primary dentition at an earlier age. The occurrences of PCO or crown malformation dose not routinely disrupt the eruption of those teeth. Periodic assessment is required to determine the need for endodontic intervention.
