title: Crown-root fracture of fused primary teeth--a case report.
abstract: In the primary dentition, traumatic injuries affecting the tooth-supporting structures are common due to increased bone resilience in children. Crown-root fracture, defined as a fracture involving enamel, dentin, and cementum, is uncommon in the primary dentition, comprising only 2% of dental traumas. This article reports the treatment and follow-up of a 2-year-old boy who suffered a traumatic crown-root fracture involving a primary anterior incisor that was fused to a supernumerary tooth.
