What is the appropriate management for a patient with denture‑related oral ulcerations and foul odor, accompanied by sinus congestion and pain radiating from the mouth to the jaw, neck, and facial region?

Management of Denture-Related Oral Ulcerations with Foul Odor and Sinus Congestion

This patient requires immediate evaluation for two distinct but potentially related conditions: denture-related candidiasis (denture stomatitis) and odontogenic sinusitis, both of which demand specific interventions beyond simple denture adjustment.

Immediate Diagnostic Considerations

The combination of mouth sores, foul odor, and unilateral sinus congestion with pain radiating from mouth to jaw/neck strongly suggests odontogenic sinusitis rather than simple viral rhinosinusitis. The foul-smelling drainage is a red flag—odontogenic sinusitis presents with unilateral symptoms and purulent, foul-smelling drainage 1. This requires different management than typical sinusitis.

Key Clinical Features to Assess:

• Unilateral vs bilateral symptoms: Odontogenic sinusitis is typically unilateral 1, 2
• Recent dental work or tooth extraction: Critical historical finding 2
• Denture fit and hygiene: Poor-fitting dentures can cause both oral ulceration and contribute to dental pathology 3
• Oral examination: Look for erythema/inflammation of palate, oroantral communication, or periapical pathology 4

Primary Treatment Algorithm

Step 1: Address the Denture-Related Oral Pathology

For denture-related candidiasis with oral ulcerations, you must treat both the infection AND disinfect the denture simultaneously 5:

• Systemic antifungal therapy: Oral fluconazole 100-200 mg daily for 7-14 days for moderate disease 5
• Denture disinfection: This is mandatory—antifungal therapy alone will fail without proper denture disinfection 5
• Complete denture removal at night: Non-negotiable for treatment success 3
• Daily denture cleaning: Patient must implement sustained behavioral change 3

For mild oral candidiasis, alternatives include clotrimazole troches 10 mg 5 times daily OR miconazole mucoadhesive buccal 50-mg tablet once daily for 7-14 days 5.

Step 2: Evaluate for Odontogenic Sinusitis

CT imaging is indicated in this case because the patient has symptoms suggesting an alternative diagnosis to simple acute bacterial rhinosinusitis 1. The foul odor, unilateral symptoms, and pain radiating to jaw/neck raise concern for odontogenic sinusitis, which requires multidisciplinary management and changes the treatment paradigm 1.

Do NOT treat this as simple sinusitis with antibiotics alone—odontogenic sinusitis requires addressing the dental source 2.

Step 3: Definitive Management Based on Findings

If odontogenic sinusitis is confirmed:

• Eliminate the dental source: This may require endodontic therapy, tooth extraction, or localized bone curettage 6
• Antibiotic therapy: Target polymicrobial aerobic-anaerobic infection 4
• Consider endoscopic sinus surgery: Often required in combination with dental treatment 2, 4
• Close any oroantral communication: Essential to prevent recurrence 4

Critical Pitfalls to Avoid

1. Do not treat the sinus symptoms alone without addressing potential dental pathology—this leads to treatment failure and recurrence 1, 2

2. Do not prescribe antifungals for denture stomatitis without ensuring denture disinfection—the biofilm on the denture will cause immediate reinfection 5

3. Do not allow continued night-time denture wear—this is a primary causative factor and must be eliminated 3

4. Do not assume this is simple viral rhinosinusitis—the foul odor and unilateral presentation demand investigation for odontogenic causes 1

Immediate Action Plan

1. Prescribe oral fluconazole 100-200 mg daily for 7-14 days 5
2. Instruct complete denture removal at night starting immediately 3
3. Provide denture disinfection protocol (daily cleaning with appropriate agents) 5
4. Order CT imaging of sinuses to evaluate for odontogenic sinusitis 1
5. Refer to dentistry/oral surgery for evaluation of dental pathology and denture fit 2
6. Consider ENT referral if CT confirms significant sinus disease requiring surgical intervention 2

The radiating pain pattern and foul odor make this a complex case requiring coordinated dental and medical management rather than simple symptomatic treatment 2, 4.
