Dental Management of Patients with Pemphigus vulgaris
Important — second opinion only. DentiCision provides an evidence-based second opinion to assist the dentist. It does not replace the treating dentist's professional clinical judgment or consultation with the patient's physician. The treating dentist retains full clinical, scientific and legal responsibility. Always verify drugs and doses against current guidelines.
Pemphigus vulgaris — confirm current activity
Pemphigus vulgaris causes fragile intra-oral blisters and erosions (often the first sign). Minor mucosal friction can trigger new lesions. Patients are frequently on high-dose corticosteroids, rituximab, azathioprine or mycophenolate (infection and adrenal-suppression risk).
Emergency vs routine management
If EMERGENCY — what to do
- • Treat pain/infection now with the gentlest technique — emergency care is never delayed.
If ROUTINE — what to do
- • Confirm disease activity to see the routine-care plan.
Clinical precautions
- • No routine antibiotic prophylaxis — consider only if neutropenic (ANC <1.0) or as advised by the treating physician; if indicated: amoxicillin 2 g 30–60 min pre-op (azithromycin 500 mg or doxycycline 100 mg if penicillin-allergic)
- • Minimise mucosal friction: lubricate lips and mirror, avoid suction against mucosa, use moistened gauze instead of dry cotton rolls, slow LA injection away from lesions, gentle impressions and smooth margins
- • Severe active oral disease: restrict care to emergencies and gentle plaque removal
- • Short appointments; prioritise oral hygiene with a soft brush and alcohol-free chlorhexidine
- • Check daily steroid dose (stress-dose cover for surgery) and immunosuppression — add these medications to the evaluation
- • Undiagnosed persistent oral erosions → refer to oral medicine for biopsy with direct immunofluorescence
Information & tests to request
- • Is Pemphigus vulgaris currently active in the mouth? — Elective treatment is deferred during an active flare because trauma worsens lesions; quiescent disease is treated with precautions.
- • Daily prednisolone-equivalent dose (mg) — This patient's condition/therapy is commonly associated with long-term corticosteroids, which can suppress the adrenal response to surgical stress. Enter the daily dose (0 if none) to determine whether supplementary stress-dose cover is needed.
