Conventional and surgical endodontic retreatment of a maxillary lateral incisor with unusual anatomy

AIM: To describe conventional and surgical endodontic treatment of a maxillary right lateral incisor with an unusual root dilaceration and to discuss the treatment outcome. SUMMARY: 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.
