Intertwined Sharpey fibers in human acellular cementum

WebbSharpey fibers are part of the principal collagenous fibers of the periodontal ligament. These fibers are embedded in the cementum and the alveolar bone which attach the tooth to the alveolus. When the cementum is visible on the teeth, this suggests that there is root exposure. This often occurs as a result of gingival recession. The cells of cementum are the entrapped cementoblasts, the cementocytes. Each cementocyte lies in its lacuna, similar to the pattern noted in bone. These lacunae also have canaliculi or canals. Unlike those in bone, however, these canals in cementum do not contain nerves, nor do they radiate outward. Instead, the canals are oriented toward the periodontal ligament and contain cementocytic processes that exist to diffuse nutrients from the ligament because it is vasculariz… Webb8 jan. 2024 · • Located in cervical half of the root and constitutes the bulk of cementum • The collagen fibers derived from Sharpey’s fibers and ground substance from cementoblasts • Covers 2/3rds of root corresponding with the distribution of primary acellular Cementum • Principal tissue of attachment • Function in anchoring of tooth small corn muffin calories
