[Animal experimental studies on the healing of tooth fractures with conventional splinting and with endodontal tension screws].
Using polchromatic sequential labeling, the healing of experimentally inflicted root fractures was observed in beagle dogs. A transition through hard substances formed from vascular connective tissue of the periodontium occurred only in the fine fracture line. It was not related to the pulp, since it also appeared after endodontal fixation. A vascular mineralization occurs in the extra-fine tissue which can be reached through a tension screw into the pulp cavity. This mineralization leads to a filling of the fragments. Dislocated root fragments heal incompletely due to interposition of connective tissue.
