Parvalbumin-immunoreactive nerve fibres were most abundant in the lingual periodontal ligaments of incisor teeth. In the part of the ligament adjacent to the alveolar bone, thick and smooth parvalbumin-immunoreactive nerve fibres left main nerve bundles and passed towards the part of the ligament adjacent to the tooth. In the ligament, halfway between the bone and tooth surfaces, these nerve fibres repeatedly branched and extended one to four twigs to produce bush-like endings. Parvalbumin-immunoreactive fibres and terminals were infrequent in the periodontal ligaments of the molar teeth. It is possible that parvalbumin-immunoreactive endings are periodontal mechanoreceptors, but at present it is difficult to account for the different representations around rat molar and incisor teeth.
小白蛋白免疫反应性神经纤维在切牙的舌侧牙周韧带中最为丰富。在韧带与牙槽骨相邻的部分，粗大且光滑的小白蛋白免疫反应性神经纤维离开主神经束，朝着韧带与牙齿相邻的部分延伸。在韧带中，位于骨表面和牙齿表面中间位置的这些神经纤维反复分支，并伸出一到四条细枝，形成灌木丛样的末梢。小白蛋白免疫反应性纤维和终末在磨牙的牙周韧带中较少见。小白蛋白免疫反应性终末有可能是牙周机械感受器，但目前难以解释大鼠磨牙和切牙周围不同的表现形式。
