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.
通过对活鼠切牙髓进行活体显微镜检查，可显示血液循环的术后病理生理反应。——在制备洞形实验24小时后，功能变化以急性炎症反应为特征。随着时间推移（7天检查），损伤可通过广泛再生（血管的重新形成和新形成、血液循环的功能适应、吻合）得到代偿，尽管在大鼠切牙中仍可见不可逆改变。——与人类牙齿组织学复查结果比较表明，仔细制备通常可避免局部急性炎症消退后留下病变。
