title: [Possibilities of healing of periodontal injuries in the apical region--an animal experimental study].
abstract: A histologic study of the healing of periodontal injuries in the area of the roots was carried out using beagle dogs. Mucobuccal injuries were inflicted in the dentoaveolar region with a saw. Polychromatic fluorescence labeling was selected to observe the reparative processes. Combined with polarization, it was possible to obtain a good evaluation of the unstained microsection. The course of healing was favorable, and the original condition was completely restored. When pure saw injuries were limited to the periodontium, we found that saw cuts extending into the dentin always left defects in the hard substance which, under favorable conditions, functionally adapted to the attachment apparatus of the teeth.
