Introduction: Traumatic dental injuries often occur to the teeth and their supporting tissues, and they are the main reasons for emergency visits to a dental clinic. Horizontal root fractures usually are characterised by a fracture line that is perpendicular to the long axis of the root. Root fractures are diagnosed through clinical and radiographic examination. Treatment depends on the position of the fracture and the extent of root involvement as well as correct diagnosis, clinical management, and radiographic follow-up. This article describes the successful management of intra alveolar horizontal root fracture. Case Presentation: A 21-year-old male patient reported with the chief complaint of pain, mobility & extrusion of teeth in the upper front region of the jaw. On the basis of clinical and radiographic findings, a diagnosis of irreversible pulpitis with horizontal root fracture in relation to upper central incisor was made. The treatment plan was comprised of reduction, semi rigid splinting, and endodontic treatment with MTA of only the coronal fragment. At recall visits, teeth were asymptomatic and responded normally to palpation and percussion. The patient was reviewed at 3 months, 6 months, and 1 year. Conclusion: The primary purpose of the treatment of fractured tooth is to keep the tooth steady and, when it's possible, vital. Adopting an appropriate treatment strategy by using material like MTA for treatment of horizontal fractures at the middle third can result in optimum healing and prolonged retention of the teeth, which would otherwise require extraction.
