Endodontic treatment of a maxillary central incisor with two roots.

AIM This clinical report presents a rare case of maxillary central incisor with two separate roots. BACKGROUND Unusual morphology of the roots and root canals may exist in any tooth. Recognition of the dental anatomy and its variations is necessary for successful endodontic therapy. It is well known that maxillary incisors are usually single-rooted teeth. CASE REPORT The root canals were instrumented with conventional hand files and Gates Glidden and obturated by using the lateral technique. Recall radiograph after 1 year shows the healing process of the preoperative apical periodontitis. CONCLUSION AND CLINICAL SIGNIFICANCE Clinicians should be aware of unexpected root canal morphology when performing root canal therapy. The present case demonstrated the importance of accurate preoperative radiograph and adequate access preparation.
