Responses of pulpal tissues were assessed histologically in teeth that had been transplanted after root formation was moderately well advanced. Degeneration occurred in the coronal third, but the area was repopulated by cells proliferating from the center of the pulp. Apically, the tissues, including the odontoblasts, remained vital and functional. Widespread intrapulpal formation of osteodentin was prominent in later observation periods. Apical closure occurred prematurely by production of osteodentin and cellular cementum in the form of an apical diaphragm; these mineralized tissues were confluent with a similarly active deposition of cellular cementum apically on the root surface.
在牙根形成中度进展良好后进行移植的牙齿中，通过组织学评估牙髓组织的反应。冠部三分之一发生了退变，但该区域被从牙髓中心增殖的细胞重新填充。在根尖部，包括成牙本质细胞在内的组织保持活力和功能。在后期观察阶段，牙髓内广泛形成骨样牙本质的现象很明显。通过以根尖横隔形式产生骨样牙本质和细胞性牙骨质，根尖过早封闭；这些矿化组织与根尖部根表面上同样活跃沉积的细胞性牙骨质相融合。
