title: [The preparation trauma of the pulp and its reactive behavior (author's transl)].
abstract: The postpreparative pathophysiological reactions of the blood circulation are shown by vital microscopy examinations of the pulp of the incisors of living rats.--After twenty-four hours from the experimental preparation of cavities, functional changes are characterized by acutely inflammatory reactions. With the passage of time (seven-day check), the damage is compensated for by extensive regeneration (re-formation and new formation of vessels, functional adaptation of the circulation of blood, anastomosing), although irreversible alterations can be seen to remain in the incisors of rats.--A comparison with the results of histological reexaminations of human teeth shows that careful preparation usually avoids lesions being left behind after the fading away of localized acute inflammations.
