This was investigated 24 weeks post-operatively by light and electron microscopy. The number of axons in the pulp at the root apex ranged from 7.5 to 76.2 per cent of the number in the contralateral control tooth. The myelinated fibres were smaller and did not penetrate as far as the coronal pulp.
术后24周通过光学显微镜和电子显微镜对此进行了研究。根尖牙髓中的轴突数量为对侧对照牙的7.5%至76.2%。有髓纤维较小,未延伸至冠髓那么远。
