Webb15 feb. 2024 · Sharpey’s fibres (SF) are poorly mineralised fibres of the connective tissue, composed mostly of several types of collagen, elastin or tenascin (e.g. Francillon-Vieillot et al. 1990; Aaron 2012).They are known primarily as providing attachment between tooth and a periodontal ligament (e.g. Ho et al. 2007).However, they occur also in other body parts, … 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.
