跨神经节轴突和终端变性发生在脑干三叉神经脊束核在特定年龄的小猫在脱落的乳牙和萌出恒牙。其退变的分布方式和顺序与成年猫牙髓摘除术后相似。牙齿传入纤维在脑干的比较代表性意味着在牙齿萌出过程中的神经支配的周边变化与中央可塑性的可能性。
Transganglionic axonal and terminal degeneration occurred reproducibly in the brain stem spinal trigeminal nucleus at specific ages in kittens during shedding of deciduous and eruption of permanent teeth. The distributional pattern and sequence of degeneration is similar to that in adult cats after tooth pulp extirpations. Comparative representation for tooth afferent fibers in the brain stem implies the possibility of central plasticity associated with peripheral changes in innervation during tooth eruption.
