Aim: The aim of this study; to present the root canal treatment and follow-up of the left upper central and lateral teeth

with lateral luxation towards the palatine after trauma.

Case: A 17-year-old male patient without any systemic disease was admitted to our clinic with complaints of pain,

swelling and mobility in the left upper anterior region teeth due to soft tissue injury because of the fight he was involved

in. In the anamnesis taken from the patient, it was learned that he was taken to the emergency room on the day of the

trauma and antibiotic treatment was started. In the clinical examination of the patient, lateral luxation towards the palatal

region of the left upper central and lateral teeth was observed and severe pain on percussion and palpation was detected

in addition to the second-degree mobility of the teeth. No foreign body was detected in the soft tissue in the radiographic

examination, and an enlargement of the periodontal ligament space was observed. Teeth 11 and 23 responded positively

to the vitality test and two sessions of root canal treatment were planned for teeth 21 and 22. After the patient’s teeth

were repositioned to their original locations under local anesthesia, a semi-rigid trauma splint was applied between

the canine and the canine for 4 weeks. During the first session after soft tissue healing, after adequate preparation of

the root canals, calcium hydroxide medicament was placed. Calcium hydroxide, which was kept for three weeks, was

removed from the root canals in the second session using a sonic irrigation activation system with sodium hypochlorite

and EDTA. Afterwards, the root canals were dried with paper point and filled with resin based root canal sealer and gutta

percha using the lateral condensation technique. One week after the coronal restoration of the teeth was completed with

composite filling, the splint was removed and follow-up was continued with control sessions.

Results: In the first month follow-up, it was determined that the patient had no clinical symptoms and the soft tissue

injury healed after root canal treatment. In the six-month follow-up, it was observed that the patient was clinically

asymptomatic, had no mobility and decreased periapical radiolucency.

Conclusion: It is seen that correct diagnosis and treatment are very important for the long-term success of teeth in

trauma injuries, which are more common in anterior teeth in young patients,
