Aphthous Ulcers in Children
Aphthous Ulcers in Children
Aphthous ulcers, also known as canker sores, are common oral lesions that frequently affect children. These painful, shallow ulcers occur on the soft tissues of the mouth, including the lips, cheeks, tongue, and gums.
Key Points:
- Aphthous ulcers are benign, self-limiting lesions
- They typically heal within 7-14 days without scarring
- The exact cause is unknown, but several factors may contribute to their development
- Treatment focuses on symptom management and prevention of secondary infection
Clinical Presentation
Aphthous ulcers in children typically present with the following characteristics:
- Round or oval-shaped ulcers with a yellow or gray center
- Red, inflamed borders surrounding the ulcer
- Size ranging from 2-8 mm in diameter
- Pain or burning sensation, especially when eating or drinking
- May occur in clusters or as single lesions
Three main types of aphthous ulcers are recognized:
- Minor aphthous ulcers: Most common, less than 1 cm in diameter, heal within 7-14 days
- Major aphthous ulcers: Larger than 1 cm, deeper, and may take up to 6 weeks to heal
- Herpetiform ulcers: Multiple small ulcers (1-2 mm) that may coalesce into larger lesions
Diagnosis
Diagnosis of aphthous ulcers in children is primarily based on clinical presentation and patient history. Key diagnostic considerations include:
- Visual examination of the oral cavity
- Assessment of pain and discomfort levels
- Evaluation of ulcer size, shape, and location
- Review of medical history and potential triggers
Differential diagnosis may include:
- Herpes simplex virus (HSV) infections
- Hand, foot, and mouth disease
- Traumatic ulcers
- Behçet's disease (rare in children)
In most cases, laboratory tests are not necessary for diagnosis. However, if ulcers are severe, persistent, or associated with systemic symptoms, further investigations may be warranted to rule out underlying conditions.
Treatment
Treatment of aphthous ulcers in children focuses on symptom management and prevention of secondary infection. The approach may include:
Topical Treatments:
- Topical anesthetics (e.g., benzocaine) for pain relief
- Antimicrobial mouthwashes (e.g., chlorhexidine) to prevent secondary infection
- Topical corticosteroids (e.g., triamcinolone acetonide dental paste) for severe cases
Systemic Treatments:
- Over-the-counter pain relievers (e.g., acetaminophen, ibuprofen)
- Vitamin B12 supplements, which may reduce recurrence in some cases
- Systemic corticosteroids for severe, recurrent cases (under medical supervision)
Supportive Care:
- Encourage a soft diet to minimize discomfort
- Advise the use of a soft-bristled toothbrush
- Recommend avoiding acidic, spicy, or salty foods that may irritate the ulcers
Prevention
While it may not be possible to prevent all occurrences of aphthous ulcers, several strategies can help reduce their frequency and severity:
- Identify and avoid potential triggers (e.g., certain foods, stress)
- Maintain good oral hygiene
- Use a soft-bristled toothbrush and avoid harsh mouthwashes
- Ensure adequate intake of vitamins and minerals, particularly B12, folate, and iron
- Manage stress through relaxation techniques or counseling
- Consider the use of protective dental wax on orthodontic appliances to prevent trauma
For children with frequent recurrences, a food diary may help identify potential dietary triggers. In some cases, allergy testing may be recommended to rule out food sensitivities.
