Aphthous ulcers are a common and aching problem. Aphthous ulcers can be categorised into three variant types: minor, major and herpetiform. Minor aphthae are often spotted on labial or buccal mucosa, the soft palate and the floor of the mouth. Major aphthae are larger and comprises deeper ulceration. Aphtha means ulcer which has been used for many years to define parts of ulceration on mucous membranes. Major aphthae can also be more likely to hurt with healing. Herpetiform aphthae naturally are more in number and have vesicles in terms of morphology. Patients with favourable aphthous ulcers should have no other cramps such as fever, adenopathy, gastrointestinal symptoms or other skin or mucous-membrane symptoms.
Aphthous stomatitis is a condition which is characterized by recurrent discrete areas of ulcerationIt is starts in childhood or adolescence as recurrent small, round, or ovoid ulcers with circumscribed margins, erythematous haloes, and yellow or gray floors. Few lesions have also have mast-cell activation and degranulation. The primary disorder appears to be the result of activation of the cell-mediated immune system. Early lesions show a cluster of macrophages and lymphocytes (predominantly cytotoxic and natural-killer T cells) at the pre-ulcerative base, proceeds by deelopment of an ulcer having a neutrophilic base and an erythematous lymphocytic ring.

Treatment of Aphthous Ulcers
Common Treatment of Aphthous Ulcers
- Early data shows treatment at onset may reduce symptoms or eradicate ulcer development. Initial studies of the use of 5% amlexanox paste at the onset of burning or pricking mucosal sensation 1-2 days before the ulcer appears can drains the pain.
- Thalidomide has been effective in unresponsive aphthous stomatitis and in Behçet syndrome.
- Local injectable anesthetics are necessary in patients with more severe pain. Injectable anesthetics are effective, but relief is brief.
- High-potency corticosteroid gels, creams, or ointments (with or without adhesive bases) have proven effective in raising healing and shortening the clinical course of RAU.
