Erythrocyte Function and Pathophysiology

Abstract Van Gieson or colloidal iron staining techniques showed in serial sections through the teeth and periodontium of the marmoset that numerous, uninterrupted (transalveolar) fibres passed from the periodontal ligament through the entire thickness of the surrounding alveolus and were not anchored as Sharpey's fibres at the bony margin. The crestal third of the alveolus of all teeth, and the interdental septum of incisors, consisted mainly of compact bone, and it was in these regions that transalveolar fibres were most readily observed. The orientation, distribution and attachment of these unique fibres to the various surfaces of the alveolus were examined in detail. Implications of these new findings are discussed as they relate to the functional role of the periodontal ligament.
