Tissue repair in intra-alveolar root fractures

      Two fractured central incisors removed six months after injury, together with their supporting alveolar bone, were examined microscopically. The reparative processes in relation to the fractures are described, and the nature of the cellular calcified tissue formed by the injured pulp is discussed. The closer identification of this tissue with dentine would appear to warrant its recognition as “cellular dentine” and serve to distinguish it from bone and cementum with which it is frequently confused.
