allergic contact stomatitis


Allergic contact stomatitis allergic contact stomatitis (allergic contactedstomatitis) is allergic drugs in the local contact, the occurrence of allergy triggered by an inflammatory disease. 【Causes which gave rise to the cause of contact stomatitis and allergy is divided into two primary incentives. The former because of exposure to the thing itself has a strong stimulating effect, can occur after any contact with lesions, such as strong acids, alkali, heat or spicy food, and other toxic substances. Contact stomatitis caused by these substances are not allergic stomatitis. Allergic contact stomatitis contact material itself is not irritating, and thus not every incidence of contact are only allergic disease. Allergic contact stomatitis and more as type â…£ hypersensitivity, or to hybrid type â…£-based allergy. Contact with objects such as silver amalgam filling material in the denture repair material, antibiotic ointment or other drugs, and many more for the hapten, hapten substances which can be used with persons with allergies epithelial membrane carrier protein and epithelial cells present in the original expansion that Langerhans (LC) cell surface immunoreactivity â…¢ - \-DR antigen, the formation of complete antigen, the T cells sensitized under the Mountain, and a large number of proliferation. When the re-exposure to the appropriate antigen (allergen), the sensitized T small roar to differentiation and proliferation, directly kill target cells, or the release of lymphokines, causing mononuclear cell infiltration with necrosis and cell-based local allergic inflammation. The allergy usually react by 48-72 hours, so called delayed hypersensitivity. Pathology Pathology】   【pathological manifestations of acute inflammatory changes. Visible edema, vasodilatation, infiltration of inflammatory cells. When the visible portion of the moss-like lesions more obvious epithelial layer tablets, the surface had mild clinical manifestations of keratosis】 【2-3 days after exposure to allergens in the local oral mucosal congestion and edema appear, or the formation of erythema, severe occurrence of water, blisters, erosions or ulcers, and even tissue necrosis, the formation of pseudomembranous exudate covering the surface. In addition to contact with parts of lesions, but also can be extended to the adjacent parts. Common clinical dental restoration materials contact stomatitis caused by, parts in contact with the denture base mucosal hyperemia, redness and swelling. Patients have a burning tingling. Severe cases, blisters can be formed, erosion or ulceration. If that does not wear a denture in a timely manner, lesions can be 1-2 weeks, the better. Amalgam or metal crown caused by allergies are more common anti-II. Clinical visible metal amalgams or dental crown in the corresponding parts of the mucous membranes and gums, the mucous membrane red, or white stripe disease, the patient has not burnin
g or tingling, unusual erosion or ulceration, known as lichenification . In addition to allergic factors, suggested that different metal filling the different electric potential of the formation of oral lesions and a tiny electric current related to the occurrence. Oral mucosa due to topical antibiotic ointment \ analgesics, mouth rinse, or allergic reactions caused by make-up lipstick, can be part of the drug exposure does not have itching or burning pain, swelling and redness can occur, and even erosion, hemorrhage, and drug-induced similar clinical manifestations of stomatitis.   【Diagnosis of clinical manifestations and diagnosis of allergies, according to history, to remove local allergens significantly improved and disappeared after the lesion. 【Treatment】 【Treatment】 1. First remove the allergy factor. Change materials, such as dentures or dental filling materials. Disable suspicious allergy drugs or cosmetics 2. Drug treatment with drug allergic stomatitis.
