The gingival fibers, (H), extend from the cementum (B) into the attached gingiva. Some fibers extend coronally into the crest of the free gingiva, some horizontally, and still other extend horizontally over the crest of the alveolar bone, (C), and then apically to connect on the facial aspect of the buccal plate of the alveolar bone.
The tissues of the periodontium combine to form an active, dynamic group of tissues. The alveolar bone (C) is surrounded for the most part by the subepithelial connective tissue of the gingiva, which in turn is covered by the various characteristic gingival epithelia.
Hereditary gingival fibromatosis (HGF), also known as idiopathic gingival hyperplasia, is a rare condition of gingival overgrowth. [1] HGF is characterized as a benign, slowly progressive, nonhemorrhagic, fibrous enlargement of keratinized gingiva. It can cover teeth in various degrees, and can lead to aesthetic disfigurement.

When gingival hyperplasia is confined to one area of the jaw, this is when it is termed an epulis fibrosa, caused by an increase in collagenous tissue with varying cellularity. [12] It may be sessile or pedunculated and is composed of fibrosed granulation tissue. Fibrous epulides are firm and rubbery, and pale pink in color.
"We use a small probe to measure the space that exists between the tooth and the gum tissue that surrounds it. If this space is between 1 mm and 3 mm, the pocket is classified as healthy. If the ...
Oral fibroma, traumatic fibroma, focal intraoral fibrous hyperplasia, fibrous nodule, oral polyp: Irritation fibroma on the left cheek of a 40-year-old man. Histopathology of irritation fibroma. Low magnification (left) characteristically [1] shows a nonencapsulated nodular mass. High magnification (right) shows fibrous connective tissue with ...
The interface between a tooth and the surrounding gingival tissue is a dynamic structure. [2] The gingival tissue forms a crevice surrounding the tooth, similar to a miniature, fluid-filled moat, wherein food debris, endogenous and exogenous cells, and chemicals float.
A study on rats suggests that the three-dimensional structure of Sharpey's fibres intensifies the continuity between the periodontal ligament fibre and the alveolar bone (tooth socket), and acts as a buffer medium against stress. Sharpey's fibres in the primary acellular cementum are mineralized fully; those in cellular cementum and bone are ...
