Abstrakt: Healthy human gingival connective tissue appears to be arranged two patterns of organization at the ultrastructural level: Pattern I (Pl) and Pattern II (PII). PI is a dense pattern of organization mainly constituted of Large, dense bundles of thick collactor fibers, whereas PII is a loose pattern of organization, mainly constituted of short thin coil fibers mixed with a line reticular network, especially located under or around basement membranes. Ultra structural immunoperoxidase labelling of types I. lII, and IV collagen demonstrates that gingival connective tissue is made of an intricate pattern of type land III collagen where type I collagen fibers are preferentially organized in large dense bundles in Fl, whereas a fibrous and fibrillar type III collagen network is predominant in P11. Type IV collagen, which does not exist in fibrous or fibrillar form, appears to be the main collagenous component of the basement membranes. [ABSTRACT FROM AUTHOR]
