Understanding Oral Ulcers in Children
Oral ulcers are a common occurrence in children, affecting approximately 9% of the pediatric population. These painful lesions can have various causes and present with distinct clinical features.
Etiology and Predisposing Factors
Oral ulcers in children can stem from multiple sources. Viral infections, such as herpangina and hand-foot-and-mouth disease, are frequent culprits. Nutritional deficiencies, particularly vitamin B12 and iron, may also lead to ulcer formation.
Gastrointestinal disorders like Crohn’s disease and celiac disease can manifest with oral ulcers. Autoimmune conditions, including pemphigus vulgaris, contribute to ulcer development in some cases.
Trauma from accidental biting, sharp foods, or dental appliances can cause localized ulcers. Stress and genetic predisposition play roles in recurrent aphthous stomatitis, a common form of oral ulceration in children.
Clinical Features and Symptoms
Oral ulcers typically present as painful, round or oval lesions with a white or yellow center and red border. They can appear on various oral surfaces, including the tongue, inner cheeks, and gums.
Children may experience:
- Pain while eating or drinking
- Difficulty speaking
- Drooling
- Refusal to eat
The size and number of ulcers vary depending on the underlying cause. Single, large ulcers may indicate trauma or infection, while multiple small ulcers are often seen in recurrent aphthous stomatitis.
Ulcer duration ranges from a few days to several weeks. Recurrent episodes are common in conditions like aphthous stomatitis, necessitating thorough evaluation and management.
Diagnosing Pediatric Oral Ulceration
Accurate diagnosis of oral ulcers in children requires careful examination and consideration of various factors. The process involves distinguishing between different potential causes and utilizing appropriate diagnostic tools.
Differential Diagnosis
Oral ulcers in children can have multiple etiologies. Common causes include viral infections like herpes simplex and hand-foot-and-mouth disease. Nutritional deficiencies, particularly of vitamin B12 and iron, may also lead to ulceration.
Autoimmune conditions such as Behçet’s disease should be considered. Traumatic ulcers from accidental biting or sharp foods are frequent in children. Recurrent aphthous stomatitis, though its exact cause remains unclear, is a common diagnosis.
Rare but serious conditions like oral cancer must not be overlooked, especially in persistent cases.
Common Diagnostic Tools and Decision Tree
The diagnostic process typically begins with a thorough patient history and physical examination. Key questions include:
- Duration and frequency of ulcers
- Associated symptoms (fever, pain, lymphadenopathy)
