Flexible wire composite splinting for root fracture of immature permanent incisors: a case report

Root fracture injuries affect up to 7% of permanent teeth, and injury in teeth with immature root formation is even rarer. The purpose of this paper was to report the case of a 7-year-old girl who experienced pain in her permanent maxillary central incisors following a fall from a bicycle. A radiographic examination revealed immature maxillary central incisors with mid-root oblique and horizontal root fractures. Splinting was performed, and the child was observed under a regular follow-up regime. After 18 months, clinical examination showed normal tooth color and position, with a positive response to the pulp test. This case report also aims to provide an insight into the splinting duration and various splinting techniques and how this can affect the prognosis.
