Root fracture represents a severe form of dental trauma, particularly in young permanent teeth. It often leads to displacement of the coronal fragment, compromising the blood supply of dental pulp. Improper management can readily result in complications such as pulp necrosis and inflammatory root resorption, ultimately affecting the long-term survival of the tooth. This article reports a complex case of an 8-year-old male patient with multiple horizontal root fractures accompanied by coronal displacement in the maxillary central incisors. Through a comprehensive conservative approach utilizing resin-reinforced fiber tape for flexible splinting, supplemented by occlusal adjustment and a protective splint, the affected teeth achieved favorable biological healing over a 2-year follow-up period. Although diffuse pulp canal obliteration occurred in the involved teeth, clinical examination revealed no abnormalities and their functional status was good.
