Conventional and surgical endodontic retreatment of a maxillary lateral incisor with unusual anatomy.
OBJECTIVE
To describe conventional and surgical endodontic treatment of a maxillary right lateral incisor with an unusual root dilaceration and to discuss the treatment outcome.


CONCLUSIONS
Root dilacerations refer to severe curvature or angulations that may occur anywhere along the length of a root. This anatomical deviation may present an unfavourable outcome if clinicians fail to recognize the difficulties. The following case report describes conventional and surgical endodontic treatment of a maxillary right lateral incisor with an unusual root dilaceration. *Root morphology may present a challenge for clinicians during root canal treatment. *Clinicians should be aware of the importance of surgical endodontics and be familiar with microsurgery principals and techniques.
