✅ Introduction
Oral ulcers affect a large portion of the population, often interfering with speech, eating, and oral hygiene. The most common types seen in clinical practice are recurrent aphthous stomatitis (RAS) and traumatic ulcers. While RAS is considered an immune-mediated inflammatory condition, traumatic ulcers result from mechanical, thermal, or chemical injury to the oral mucosa.

✅ Clinical Features

➤ Aphthous Stomatitis
▪️ Etiology: Multifactorial; includes genetic predisposition, stress, hormonal changes, nutritional deficiencies (B12, folate, iron), and hypersensitivity reactions.
▪️ Lesion Characteristics: Round or oval ulcers with a yellow-gray pseudomembrane and erythematous halo, typically found on non-keratinized mucosa (buccal, labial, ventral tongue).
▪️ Symptoms: Pain, burning sensation, and discomfort during eating or speaking.
▪️ Duration: 7–14 days, recurrent pattern.
▪️ Types: Minor, major, and herpetiform aphthae.

➤ Traumatic Ulcers
▪️ Etiology: Caused by mechanical irritation (biting, sharp tooth edges, orthodontic appliances), thermal burns, or chemical agents (aspirin, alcohol-based mouthwash).
▪️ Lesion Characteristics: Irregular borders, often surrounded by erythema; may be covered by a yellow fibrinous exudate.
▪️ Location: Usually on keratinized mucosa (tongue borders, palate, gingiva).
▪️ Symptoms: Localized pain and tenderness.
▪️ Duration: Heals within 7–10 days after removing the traumatic factor.

📊 Pharmacological Treatment in Children

Condition	Medication	Dosage and Duration

Traumatic Ulcer	Benzocaine 7.5% gel	Apply small amount 2–3 times daily
—	Hyaluronic acid spray	Apply twice daily to affected area

💬 Discussion
Differentiating between aphthous stomatitis and traumatic ulcers is crucial, as the former may be associated with systemic diseases such as Behçet’s syndrome, inflammatory bowel disease, or celiac disease. Traumatic ulcers, conversely, typically heal once the causal factor is removed.
Topical corticosteroids remain the mainstay treatment for aphthous ulcers, while barrier and healing agents suffice for trauma-induced lesions. Regular oral examinations and patient education on trauma prevention and nutritional balance play key roles in reducing recurrence.

✍️ Conclusion
Although aphthous stomatitis and traumatic ulcers share similar clinical manifestations, their etiology and management differ. A thorough clinical history and lesion evaluation are vital to determine the correct diagnosis. Topical corticosteroids are effective for aphthous ulcers, whereas eliminating the irritant is sufficient for traumatic ulcers.

🔎 Recommendations

1. Encourage patients to maintain good oral hygiene and avoid trauma.
2. Evaluate for nutritional deficiencies in recurrent aphthous cases.
3. Use topical corticosteroids only under professional supervision.
4. Educate patients about non-irritant diets and stress management.
5. Reassess ulcers persisting beyond two weeks to rule out malignancy or systemic conditions.

✅ Diagnosis & Clinical Features

➤ Clinical Presentation
° Aphthous stomatitis: small, round/ovoid ulcers with gray-white or yellowish pseudomembrane and red halo; typically heal in 7–14 days and may recur.
° Herpetic gingivostomatitis: grouped vesicles evolving into ulcers, often with fever, common under age six.
° Hand-Foot-Mouth Disease / Herpangina: small ulcers (2–4 mm) on soft palate or tonsillar pillars, often accompanied by systemic signs like fever and lesions on palms/soles.
° Traumatic ulcers: solitary ulcers with yellowish pseudomembrane on lips, tongue or buccal mucosa; heal within ~10 days if cause removed.

➤ Diagnostic Work-up
Diagnosis is primarily clinical, supported by full history and examination. Laboratory tests (blood count, nutritional panels), lesion cultures, or biopsy may be indicated for atypical, persistent, or recurrent ulcers; malignancy must be considered if lesions persist beyond two weeks

✅ Etiology & Predisposing Factors

° Aphthous ulcers (RAS): Immune-mediated with triggering factors including trauma, stress, nutritional deficiencies (B-1, B-2, B-6, B-12, iron, folate), GI disorders (e.g. celiac, IBD), food allergies, and chemical exposures like sodium lauryl sulfate (SLS).
° Viral causes: Coxsackievirus (hand-foot-mouth, herpangina), HSV-1 (herpetic ulcers), and other viral agents.
° Contact allergens: Substances such as cinnamaldehyde, Balsam of Peru, toothpaste additives, and nickel may provoke allergic stomatitis with ulceration.
° Systemic diseases: Behçet’s disease (oral ulcers plus ≥2 other hallmark signs), immune compromise, gastrointestinal or hematological disorders.

✅ Management & Treatment Strategies

➤ General Supportive Care
° Encourage hydration and soft, bland diet; avoid spicy, acidic, or salty foods.
° Pain control with acetaminophen or ibuprofen as needed.

➤ Topical & Local Therapies
° Topical corticosteroids: Gels or pastes (e.g., triamcinolone) applied 2–4× daily can reduce severity and duration; in rare cases, local injection may be used.
° Amlexanox paste 5%: Early application at prodrome may mitigate ulcer development and pain.
° Mouth rinses or elixirs with anesthetics or coatings (e.g., lidocaine, diphenhydramine, antacid-containing rinses) for symptomatic relief, especially in viral ulcers.

➤ Adjunct & Preventive Measures
° Nutritional supplements (vitamin B12, zinc, iron) may reduce recurrence in deficiency states.
° Avoid SLS-containing oral hygiene products.
° Stress reduction may be beneficial, although evidence is limited.

➤ Specialist Referral
° Refer to pediatrician or oral medicine specialist if ulcers persist >2 weeks, systemic symptoms develop, dehydration/poor intake, failure to thrive, or suspicion of systemic disease

💬 Discussion
Effective management of pediatric oral ulcers relies on discerning their etiology and tailoring therapy accordingly. While most cases are benign and self-limiting, attention to hydration, pain relief, proper oral hygiene, and trigger avoidance significantly improves outcomes. Identification and correction of underlying causes—such as nutritional deficiencies or systemic conditions—can reduce recurrence and morbidity. Vigilance is essential for atypical, persistent, or severe presentations that may signal systemic or malignant processes.

💡 Conclusions
Pediatric oral ulcers are common and usually benign, yet they can significantly impact comfort and nutrition. A systematic approach—clinical diagnosis, symptomatic support, targeted topical therapy, and addressing underlying factors—generally leads to resolution. Referral and further evaluation are warranted when lesions persist, recur frequently, or occur in the context of systemic signs.
