Medical Care
Identify and correct predisposing factors for recurrent aphthous stomatitis (RAS). Ensure that patients brush atraumatically (eg, with a small-headed, soft toothbrush) and avoid eating particularly hard or sharp foods (eg, toast, potato crisps) and avoid other trauma to the oral mucosa.
SLS should be avoided if implicated as a predisposing factor. Any iron or vitamin deficiency should be corrected once the cause of that deficiency has been established. If an obvious relationship to certain foods is established, these should be excluded from the diet. Patch testing may be indicated to reveal allergies. The occasional patient who relates ulcers to her menstrual cycle or to use of an oral contraceptive may benefit from suppression of ovulation with a progestogen or a change in the oral contraceptive. Causal drugs should be excluded.
In most cases, the natural history of RAS is one of eventual remission. However, for some patients, remission occurs spontaneously several years later; thus, treatment is indicated in these patients if discomfort is significant. Relief of pain and reduction of ulcer duration are the main goals of therapy. Objective evidence shows the most efficacy from corticosteroids and antimicrobials used topically.
- Vitamin B12 used orally may have some effect
- Topical corticosteroids (TCs) remain the mainstays of treatment. A spectrum of different TCs can be used. At best, TCs reduce painful symptoms but not the rate of ulcer recurrence. The commonly used preparations are as follows:
- Hydrocortisone hemisuccinate pellets (Corlan), 2.5 mg used 4 times daily
- Triamcinolone acetonide in carboxymethyl cellulose paste (Adcortyl in orabase [withdrawn in some countries], Kenalog), administered 4 times daily
- Betamethasone sodium phosphate as a 0.5-mg tablet dissolved in 15 mL of water to make a mouth rinse, used 4 times daily for 4 minutes each time
- Hydrocortisone and triamcinolone preparations are popular because neither causes significant adrenal suppression; however, ulcers still recur.
- Betamethasone, fluocinonide, fluocinolone, fluticasone, and clobetasol are more potent and effective than hydrocortisone and triamcinolone, but they carry the possibility of some adrenocortical suppression and a predisposition to candidiasis.
- Topical tetracyclines may reduce the severity of ulceration, but they do not alter the recurrence rate. A doxycycline capsule of 100 mg in 10 mL of water administered as a mouth rinse for 3 minutes or tetracycline 500 mg plus nicotinamide 500 mg administered 4 times daily may provide relief and reduce ulcer duration. Avoid tetracyclines in children younger than 12 years who might ingest them and develop tooth staining.
- Chlorhexidine gluconate mouth rinses reduce the severity and pain of ulceration but not the frequency.
- Anti-inflammatory agents can help; a spectrum of topical agents such as benzydamine and amlexanox may help. Benzydamine hydrochloride mouthwash, though no more beneficial than a placebo, can produce transient pain relief.
- If RAS fails to respond to local measures, systemic immunomodulators may be required. A wide spectrum of agents has been suggested as beneficial, but few studies have been performed to assess their efficacy (or their adverse effects are significant). Thalidomide 50-100 mg daily is effective against severe RAS, although ulcers tend to recur within 3 weeks. Teratogenicity, neuropathy, and other adverse effects dissuade most physicians from its use.
- Few, if any, of the other medications used for RAS have undergone serious scientific evaluation. These include transfer factor, gamma-globulin therapy, sodium cromoglycate lozenges, dapsone, colchicine, pentoxifylline, levamisole, colchicine, azathioprine, prednisolone, azelastine, alpha 2-interferon, ciclosporin, deglycerinated liquorice, 5-aminosalicylic acid (5-ASA), prostaglandin E2 (PGE2), sucralfate, diclofenac, and aspirin.
