Abstract
BACKGROUND

Complicated crown–root fracture (CRF) involves severe injury to the crown, root, and pulp, and may be accompanied by multiple root fractures. The loss of a tooth has lifelong consequences for children and teenagers, but the maintenance of pulp health and the calcific healing of multiple root fractures are rarely reported in the literature.

CASE SUMMARY

This case reports healing of a permanent tooth with complicated crown–root and additional root fractures, in which pulp health was maintained. A 10-year-old girl fell and fractured the root of her maxillary left central incisor at the cervical level. After the coronal fragment was repositioned, the tooth was splinted until the tooth was no longer mobile, 2 years later. Eight years after treatment, the tooth has remained asymptomatic with vital pulp and localized gingival overgrowth. Cone-beam computed tomography revealed not only calcified healing of the CRF but also spontaneous healing in an additional undiagnosed root fracture. The fracture line on the enamel could not be healed by hard tissue and formed a groove in the cervical crown. It was speculated that the groove was related to the localized gingival overgrowth.

CONCLUSION

This case provides a clinical perspective of the treatment of a tooth with a complicated CRF and an additional root fracture.

Keywords: Complicated crown–root fracture; Multiple root fracture; Spontaneous healing; Cone-beam computed tomography; Long-term follow-up; Case report

Core Tip: This case describes the conservative management of a complicated crown–root fracture with an additional root fracture that did not receive any surgical or endodontic treatment. A satisfactory outcome was achieved with an 8-year follow-up. The case report offers significant insights into the management of such dental injuries.
