✅ Introduction
Oral ulcerations are common presentations in dental practice, often causing discomfort, impaired nutrition, and anxiety in patients. Aphthous stomatitis and traumatic ulcers are among the most frequent ulcerative lesions encountered. Distinguishing between them is essential to avoid misdiagnosis and unnecessary interventions (Scully & Porter, 2008).
Aphthous ulcers are typically recurrent, immune-mediated lesions, while traumatic ulcers result from mechanical, thermal, or chemical injury. Understanding their distinct features ensures appropriate treatment and patient education.

Despite their similar appearance, their etiology, pathophysiology, and management differ significantly. Accurate differentiation is essential for effective treatment and prevention of recurrence.

✅ Definition and Etiology

➤ Aphthous Ulcers (Recurrent Aphthous Stomatitis - RAS)
▪️ Definition: Small, round, or oval mucosal ulcers with a yellow or gray center surrounded by an erythematous halo.
▪️ Etiology: Multifactorial; associated with genetic predisposition, nutritional deficiencies (vitamin B12, folate, iron), stress, hormonal changes, and immune dysregulation (Akintoye & Greenberg, 2014).
▪️ Typical Sites: Non-keratinized mucosa such as the labial, buccal, and ventral tongue surfaces.

➤ Traumatic Lesions
▪️ Definition: Localized mucosal breakdown caused by mechanical (biting), chemical (aspirin burn), or thermal trauma (hot food).
▪️ Etiology: Accidental injuries from sharp teeth, dental appliances, or iatrogenic causes during dental procedures.
▪️ Typical Sites: Areas directly exposed to trauma—lateral tongue, buccal mucosa, or lip mucosa.

Mucocele is a benign lesion that occurs in the oral mucosa and is the product of an alteration in the minor salivary glands. It is recognized as a swelling with mucous content, well circumscribed, and bluish in color.

✅ Clinical Characteristics

| Aphthous ulcers often recur periodically, whereas traumatic ulcers heal promptly once the irritant is eliminated.

✅ Differential Diagnosis
Differentiating aphthous ulcers from other ulcerative oral diseases is essential. Conditions such as herpetic stomatitis, lichen planus, and oral cancer must be excluded through history, lesion location, and biopsy if necessary.

➤ Key diagnostic indicators:
▪️ Absence of trauma history suggests aphthous origin.
▪️ Lesions on keratinized mucosa often point toward traumatic or herpetic causes.
▪️ Recurrent, self-limiting pattern indicates aphthous stomatitis.

✅ Modern Treatment Approaches

📊 Comparative Table: Modern Treatments for Oral Ulcers

Treatment Option	Advantages	Limitations
Topical Corticosteroids (e.g., Triamcinolone Acetonide 0.1%)	Reduces inflammation and pain; promotes healing in aphthous ulcers	Possible candidiasis with prolonged use
Topical Antiseptics (e.g., Chlorhexidine Mouthwash 0.12%)	Prevents secondary infection; aids in epithelial healing	May cause staining and taste alteration
Laser Therapy (Low-Level Laser)	Provides immediate pain relief; accelerates tissue regeneration	Requires specialized equipment and training
Topical Analgesics (e.g., Lidocaine Gel 2%)	Provides symptomatic pain control	Short duration; does not accelerate healing

💬 Discussion
Accurate differentiation between aphthous and traumatic ulcers prevents unnecessary pharmacological treatments and misdiagnosis of recurrent lesions. The use of low-level laser therapy (LLLT) and topical corticosteroids represents a modern evidence-based approach for managing aphthous lesions (Caccianiga et al., 2022).
For traumatic lesions, eliminating the causal factor remains the cornerstone of therapy. Dentists should conduct habit analysis and appliance adjustment to prevent recurrence.

✍️ Conclusion
Aphthous ulcers and traumatic oral lesions share overlapping features but differ in etiology, recurrence, and management. Recognizing these distinctions allows clinicians to deliver targeted treatment and improve patient comfort. Combining clinical observation with patient history remains the most effective diagnostic strategy.

✅ Definition
Recurrent aphthous stomatitis is a chronic, relapsing condition characterized by round or oval ulcers with a yellowish fibrinous center and an erythematous halo, occurring on non-keratinized oral mucosa such as the buccal mucosa, floor of the mouth, and labial surfaces. Episodes typically recur every 1–4 months, lasting 7–14 days per episode.

✅ Etiology
The etiopathogenesis of RAS is multifactorial, involving a combination of genetic, immunologic, microbial, and environmental factors:

▪️ Genetic predisposition: Positive family history in up to 40% of cases.
▪️ Immune dysregulation: Altered T-cell response and increased TNF-α levels.
▪️ Nutritional deficiencies: Low levels of vitamin B12, folate, iron, and zinc are commonly associated.
▪️ Stress and trauma: Minor oral trauma can trigger ulcer formation.
▪️ Allergic or microbial factors: Hypersensitivity reactions to certain foods (e.g., chocolate, nuts) or bacteria.
▪️ Systemic diseases: Behçet’s disease, Crohn’s disease, and celiac disease must be ruled out.

Dental Article 🔽 Differential Diagnosis of Perioral Dermatitis: Clinical Insights and Management ... Since its clinical presentation overlaps with other dermatoses such as acne vulgaris, rosacea, seborrheic dermatitis, and contact dermatitis, establishing a clear differential diagnosis is critical for effective treatment and prognosis.

✅ Diagnosis
Diagnosis is clinical, based on history, lesion morphology, recurrence pattern, and exclusion of systemic conditions.
Typical RAS lesions are:

▪️ Minor aphthae: less than 10 mm, heal without scarring.
▪️ Major aphthae: more than 10 mm, last longer, may scar.
▪️ Herpetiform aphthae: Multiple pinpoint ulcers that coalesce.
Laboratory tests (CBC, ferritin, folate, vitamin B12, and celiac antibodies) are indicated when recurrent or severe ulcers are present.
