P>Aim
This report describes a permanent maxillary incisor tooth with two roots possibly caused by trauma to the predecessor primary tooth.
Summary
Diagnosis, aetiology, clinical implications and endodontic and aesthetic treatment of an incisor tooth with two roots are presented. Diagnosis, early intervention by a multidisciplinary team and clinical and radiographic examination of patients who suffer trauma to primary teeth are of importance to minimize or avoid damage to successor teeth.
Key learning points
A possible sequelae of trauma to a primary tooth is root duplication in the permanent tooth.
Root duplication is a rare anomaly that has its diagnosis based on the radiographic examination.
Careful diagnosis and follow-up are necessary to prevent future complications related to the successor tooth.
