Dental traumatic injuries 1 frequently affect the teeth and oral tissues of toddlers. 2 Horizontal root fractures following trauma in the primary dentition have a prevalence of 2.46%, 3 and are considered to be rare. 4 The treatment for horizontal root fractures was once considered to be extraction. 5,6 Although there is little scientific support for treatments in the primary dentition, 7 the main reason for treating fractured teeth is to maintain the pulp. 8 Frequently, observation is the most appropriate choice in emergency situations, unless there is risk of ingestion, aspiration, or occlusal interference. 7 The International Association of Dental Traumatology (IADT) guidelines state that to establish a treatment protocol the clinician must evaluate the individual clinical aspects, the possibility of compliance, and also consider the immediate and long-term outcomes of the treatment options versus non-treatment. 1 Thus, an accurate examination and diagnosis are essential for the successful management of a root fractured tooth 9 and the treatment protocol will depend on the displacement of the fractured segment, the location of the fracture line and the state of the pulp. 6 Previous articles in the literature have reported the management of horizontally fractured roots in primary teeth with splinting, 4,10,11 and spontaneous healing of root fractured permanent teeth without any treatment has also been described. [12][13][14] This report presents a case of a horizontal root fracture in a primary central incisor with non-invasive management that resulted in satisfactory long-term preservation of the tooth over an eight-year follow-up period.
