Irritation fibroma is a type of fibroma that occurs on the mucosa of the oral cavity. [2] Irritation fibromas are common benign tumors that are asymptomatic and resemble scarring . They are caused by prolonged irritation in the mouth, such as cheek or lip biting, rubbing from teeth, and dental prostheses .
The cystic fibroma (fibroma cysticum) has central softening or dilated lymphatic vessels. The myxofibroma (fibroma myxomatodes) is produced by liquefaction of the underlying soft tissue. The cemento-ossifying fibroma is hard and fibrous, most frequently seen in the jaw or mouth, sometimes in connection with a fracture or another type of injury.
Peripheral giant-cell granuloma (PGCG) is an oral pathologic condition that appears in the mouth as an overgrowth of tissue due to irritation or trauma. Because of its overwhelming incidence on the gingiva, the condition is associated with two other diseases, pyogenic granuloma and peripheral ossifying fibroma. These three diseases are ...
Giant-cell fibromas are commonly located on the gingiva.The tongue is the second most common location, followed by the palate or buccal mucosa.Giant-cell fibromas are usually asymptomatic and appear as 0.5-1cm pedunculated or sessile lesions with a pebbly or bosselated surface.
The fibroblasts are phenotypically modified, and the fibers they form are more stable, produce thicker bundles that progressively become less elastic. once the original loosely arranged fibrous tissue is replaced by the ongoing fibrosis, the movability of the oral tissues is reduced, there is loss of flexibility and reduced opening of the mouth.
However, they are all similar in cause and nature, the overproduction of the cells of the mucosa, primarily the epithelial cells, also fibrous myxoid and low inflamed tissue due to irritation. Fibroepithelial polyps are usually pale, firm to touch, and painless but further irritation can cause abrasion and then ulceration or bleeding. They are ...
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 ...
Not to be confused with ossifying fibroma. This is a long-standing fibrous epulis in which bone has begun to form. It is believed that irritants and trauma cause the growth. Dental appliances, poor restorations and subgingival plaque and calculus are all examples of possible causes.
