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 teeth, viewed from the right. A gomphosis, also known as a dentoalveolar syndesmosis, [11] or 'peg and socket joint' [12] is a joint that binds the teeth to bony teeth sockets in the maxillary bone and mandible. Gomphos is the Greek word for "bolt". The fibrous connection between a tooth and its socket is a periodontal ligament ...
Also the alveolar ridge (the gum where the teeth erupt up from, or if missing, where they used to be) and the hard palate (roof of the mouth). The most common are fibrous nodules called fibroepithelial polyps and epulides. Other hyperplastic reactive hyperplastic lesions include those associated with dentures, and papillomas.
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. [2] Fibrous enlargement is most common in areas of maxillary and mandibular tissues of both arches in the mouth. [1]
Epulis fissuratum is a benign hyperplasia of fibrous connective tissue which develops as a reactive lesion to chronic mechanical irritation produced by the flange of a poorly fitting denture. [1] More simply, epulis fissuratum is where excess folds of firm tissue form inside the mouth, as a result of rubbing on the edge of dentures that do not ...
Periapical COD occurs most commonly in the mandibular anterior teeth while focal COD appears predominantly in the mandibular posterior teeth. Florid COD is an extensive variant of periapical COD where lesions occur in multiple quadrants which can encompass the maxilla and mandible, and infrequently can cause jawbone deformity.
In the teeth, Sharpey's fibres are the terminal ends of principal fibres (of the periodontal ligament) that insert into the cementum and into the periosteum of the alveolar bone. [1] A study on rats suggests that the three-dimensional structure of Sharpey's fibres intensifies the continuity between the periodontal ligament fibre and the ...
Osteoclastic and osteoblastic remodeling contributes to the change of normal bone to fibrous tissue and cyst formation. As noted by the name, the patient's face becomes enlarged and disproportionate due to the fibrous tissue and atypical bone formation. The sponge-like bone formations lead to early tooth loss and permanent tooth eruption problems.
