Twelve weeks after reimplanting lower canines the distribution and characteristics of myelinated and non-myelinated axons within the periodontal ligament were investigated by light and electron microscopy. The ligament was examined at 2-mm intervals along the length of the root of four reimplanted teeth and of the contralateral canines, which served as controls. In each case the periodontal ligament was reinnervated. In two of the teeth, which showed extensive apical resorption, the innervation was much less than in control teeth. In two teeth showing minimal or no apical resorption the degree of innervation at the most apical level did not differ significantly from controls.
在下颌犬齿再植12周后,通过光学显微镜和电子显微镜研究了牙周膜内有髓和无髓轴突的分布及特征。沿着四颗再植牙和作为对照的对侧犬齿的牙根长度,每隔2毫米对牙周膜进行检查。在每种情况下,牙周膜都实现了重新神经支配。在两颗出现广泛根尖吸收的牙齿中,神经支配远少于对照牙。在两颗根尖吸收最小或未出现根尖吸收的牙齿中,最根尖水平的神经支配程度与对照牙无显著差异。
