The sinus tract pointed to periapical radiolucency at the apex of the tooth #11. Sinus tract tracing was performed through inserting size 30 gutta-percha in the fistulae area, and a radiograph was exposed.

Radiographic examination revealed two roots with inadequate root canal treatment and periapical radiolucency of #11. The tooth had no mobility and was not tender to percussion. The tooth had a poorly fitting crown which was attached to the adjacent crown. The intraoral examination revealed a buccal sinus tract in the attached gingiva between the right maxillary central and lateral incisors. She was taking an antibiotic (Augmentin 1 g bds) for the past 5 days. The patient was healthy and did not have any relevant medical history or any allergies. Later, she developed swelling and pus drainage.

While preparing the crown, her dentist informed her that she needed endodontic therapy, which she had done, and then, a crown was placed on the tooth. The patient reported that she had spacing between her teeth and went to a dentist 1 year ago to close it. , The present study presents a clinical case depicting endodontic retreatment of a maxillary central incisor with two root canals and two roots, detected through radiographic evaluation and microscopic examination.ДЄ 38-year-old Saudi female patient has been reported to our private dental clinic complaining of swelling and pus draining from the right maxillary central incisor (#11). , Although there have been some reports of additional canals. Most studies indicate that maxillary central incisors have one root and one canal. Therefore, it is important that dentists have an extensive knowledge of the internal dental anatomy of the teeth and consider the morphological variations of root canal systems, as well as an arsenal of tools to assist in the discovery of these variations. These errors can manifest if the root canals are not found or debrided completely, as variation in the number of roots or in canal configuration may impact endodontic treatment and affect the prognosis of root canal therapy. ,, , Failure of endodontic treatment can occur for several reasons, such as diagnostic errors, errors in debridement and shaping of the root canal systems, persistence of the infection in the root canal system, poor restorations, and instrument fractures. The most important factor in the prevention or healing of endodontic disease is the eradication of most of the bacteria in the root canal system, which can be done through top-quality chemo-mechanical cleaning and shaping of the root canal. Maxillary Central Incisor with Two Roots вЂ“ A case report. Keywords:В Anatomic variations, diagnosis, maxillary central incisor, root canal re-treatment, Vertucci classification Retreatment was done and the tooth was asymptomatic clinically and radiographically at 6 months follow-up. The case was initially misdiagnosed and not treated fully, however, correct diagnosis through detailed examination and evaluation, using tracing and imaging. This report portrays an endodontic re-treatment of a maxillary central incisor of a healthy 38-year-old Saudi female patient with two canal systems and two roots presented to the clinic complaining of swelling and pus drainage. The maxillary central incisor usually presents with one root canal system within one root. Knowledge of the external and internal dental anatomy and its variations is a prime factor of success of endodontic therapy.
