Aim: The aim of this case report is to present three different patients who had horizontal and vertical root fractures of young permanent teeth, its diagnosis, clinical and radiographic findings, treatment, and long-term follow-up and success rate. Background: Root fractures are relatively rare with the prevalence of 0.5–7% in permanent and 2–4% in deciduous dentition. Timely intervention and accurate treatment procedures are the main concerns for long-term success of root fractures. Case description: Case I and case II had horizontal fracture of immature permanent tooth. Patients reported with a chief complaint of pain in their upper central incisors. As a result of radiographic examination, horizontal root fractures were diagnosed. Teeth were treated with a mineral trioxide aggregate (MTA) plug (case I and case II) and repositioning and splinting (case II). Case III had vertical root fracture of immature permanent tooth. Tooth was treated with apexification (sectional obturation) and sealed with resin-modified glass ionomer cement (RMGIC) till the fracture site and flowable light cure restoration. Patients were scheduled for follow-up visits at different time intervals. Radiographic evidence indicated ongoing root development in these immature teeth. Normal color and mobility were observed, and no pain was noted during horizontal and vertical percussion tests. Conclusion: The present case report shows a favorable and stable outcome of timely treatment and sound healing of various types of root fracture. Long-term follow-up of patients with trauma is essential because pathological changes can occur several years following injury. Clinical significance: The latest treatment modalities and long-term follow-up showed clinical success.
