Webb1 dec. 1994 · The Sharpey's fiber bundles ran nearly perpendicular to the bone matrix fiber bundles. The other fixed samples were embedded in polyester resin, ground and observed by backscattered electron signals in an SEM (BSE). In the BSE images, even thin Sharpey's fibers deeply penetrating the alveolar bone were hypomineralized. Webbrection of Sharpey's fibers in cementum and bone has a relationship to the deposition of both cementum and bone. This suggests that new layers of cementum become nec essary when change in position produces bending of Sharpey's fibers at the point of insertion into cementum. 2.
