Behçet disease
Overview
Board takeaway: Recurrent oral ulcers with genital, eye, skin, or systemic findings warrant medical assessment; manage oral comfort while the systemic disease is treated.
What distinguishes Behçet disease from isolated recurrent aphthous ulcers?
Behçet disease is a relapsing multisystem vasculitis. Recurrent oral ulcers may precede genital ulcers, uveitis, skin lesions, arthritis, vascular disease, or neurologic and gastrointestinal involvement. A pathergy response can occur. HLA-B51 is an association, not a diagnostic test on its own.
What oral findings occur in Behçet disease?
Painful recurrent aphthous ulcers may involve the lips, cheeks, tongue, palate, and pharynx. Multiple or severe lesions can prevent comfortable eating and brushing. Secondary gingival inflammation, plaque accumulation, and caries may follow impaired hygiene; ulcer burden and disease activity vary.
How should dental care be planned during a Behçet flare?
Assess hydration, nutrition, ulcer severity, and systemic symptoms. Coordinate treatment with rheumatology; defer uncomfortable elective procedures during a substantial flare while addressing urgent infection or pain. Use gentle hygiene and local symptom control compatible with the medical plan. Review immune suppression, glucocorticoid exposure, blood counts when relevant, and prescribed antithrombotic treatment before invasive care.
How are oral ulcers and systemic Behçet disease treated?
Topical corticosteroids and other local measures can help oral ulcers; systemic treatment is selected for the involved organ and severity. Colchicine and immunomodulatory therapies may be used by the medical team. Ocular, neurologic, and major vascular disease require specialist treatment rather than local ulcer care alone.
What determines prognosis in Behçet disease?
Many patients have relapsing mucocutaneous disease with manageable symptoms. Eye disease can threaten vision, and neurologic or major vessel disease can be disabling or life-threatening. New eye pain or visual change, neurologic symptoms, or signs of vascular complications require prompt medical escalation.
