In theory, gingival fibers are the protectors against periodontitis, as once they are breached, they cannot be regenerated.When destroyed, the gingival sulcus (labelled G in the diagram) increases in depth apically, allowing more debris and bacteria to remain in intimate contact with the delicate sulcular and junctional epithelia for longer times.
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.
Oral submucous fibrosis (OSF) is a chronic, complex, premalignant (1% transformation risk) condition of the oral cavity, characterized by juxta-epithelial inflammatory reaction and progressive fibrosis of the submucosal tissues (the lamina propria and deeper connective tissues). As the disease progresses, the oral mucosa becomes fibrotic to the ...
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. The depth of this crevice, known as a sulcus , is in a constant state of flux due to microbial invasion and subsequent immune response.
The tissues that sit above the alveolar bone crest are considered the free gingiva. In healthy periodontium, the gingival margin is the fibrous tissue that encompasses the cemento-enamel junction, a line around the
Sharpey's fibres (bone fibres, or perforating fibres) are a matrix of connective tissue consisting of bundles of strong predominantly type I collagen fibres connecting periosteum to bone. They are part of the outer fibrous layer of periosteum, entering into the outer circumferential and interstitial lamellae of bone tissue.
Overall, the clinical appearance of the tissue reflects the underlying histology, both in health and disease. When gum tissue is not healthy, it can provide a gateway for periodontal disease to advance into the deeper tissue of the periodontium, leading to a poorer prognosis for long-term retention of the teeth. Both the type of periodontal ...
A peripheral ossifying fibroma, also known as ossifying fibrous epulis, is “a gingival nodule which is composed of a cellular fibroblastic connective tissue stroma which is associated with the formation of randomly dispersed foci of mineralised products, which consists of bone, cementum-like tissue, or a dystrophic calcification.
