Collagen cross-linking in bovine gingiva.
Tissue samples from 5 different sites of 6 bovine mandibles were used to quantify collagen cross-links as moles cross-link per mole of collagen. Gingiva contained primarily 3 reducible cross-links, deH-DHLNL, deH-HHMD, and deH-HLNL, and relatively small amounts of non-reducible cross-links. The cross-link density varied from site to site within the same mandible. DeH-DHLNL showed the most significant increase from anterior to posterior; the content in the retromolar region was 3-fold greater than in the anterior lingual site. Histologically, the posterior samples, especially the retromolar gingiva, contained less mature (thinner) collagen bundles. These findings suggest that the maturity of bovine mandibular gingival collagen varies at different sites.
