coronal pulp

Upper left first molar of a rat randomly from each group was split and the freshly coronal pulp was obtained for TEM observation.

在每组中随机抽取一只大鼠，处死后劈开左侧上颌M1牙冠，取出牙髓经固定后切片，进行透射电镜观察。

When the coronal pulp was moderately and intense chronic simple pulpitis, the 1/ 3~ 1/ 2 root pulp had pathological changes.

冠髓呈中、重度慢性单纯性或化脓性牙髓炎时，1/3～1/2的根髓有病变。

Results: Coronal pulp tissue of 77.8% of deciduous teeth with deep caries showed chronic inflammation to various degree or chronic pulpitis with acute attack.

结果：77.8%的冠髓组织有不同程度的慢性炎症和慢性牙髓炎急性发作。

In the coronal pulp, the number of CGRP IR nerve fibers decreased, but the background staining was heavier.

而冠髓CGRP-IR神经纤维减少，背景染色加重。
