A case is presented in which an untreated root fracture in a maxillary central incisor of an adult male was found radiographically 10 years after injury. The tooth was removed and the area of the root corresponding to the fracture line was examined by SEM while the remaining tooth was processed for decalcified sections. Calcification of the coronal pulp associated with extensive tissue atrophy and normal pulp tissue apically was observed. Two barriers composed of dentinal and cemental hard tissue were present apically in the coronal fragment and in the fracture line.
