Abstract:

Permanent root fracture is a prevalent form of dental trauma, and its prognosis is influenced by numerous factors. While tooth extraction is commonly considered as the primary treatment option, the new dental trauma guidelines released by the International Association of Dental Trauma (IADT) presents a different perspective. For teeth with fractured root but intact pulp and good periodontal condition, hard tissue healing is probably to occur at the fracture line, so that they are likely to be preserved through appropriate clinical measures. This article systematically elucidated the biological basis, mechanisms of healing, and treatment strategies for teeth with fractured root based on a comprehensive literature review.
