对2只犬的14颗未成熟门牙进行实验性机械打击45 d后的牙髓反应进行组织病理学观察。创伤后临床检查显示，机械打击未造成牙齿断裂、移位或松动。所有标本中较显著的牙髓反应是冠状髓的凝固性坏死和根状髓中央区域的透明化。所有损伤牙均可见冠状或根状坏死组织内营养不良钙化，无炎症浸润。
The pulpal reactions of 14 immature incisors of two dogs were histopathologically evaluated 45 days after experimental mechanical blows that did not, as shown by post-traumatic clinical examination, cause fracture, displacement or loosening of the teeth. The more significant pulpal reactions in all specimens were the coagulation necrosis of the coronal pulp and the hyalinization of the central region of the radicular pulp. Dystrophic calcifications within coronal or radicular necrotic tissue, and absence of inflammatory infiltration were also observed in all traumatized teeth.
