From the Guidelines

The workup for multiple aphthous ulcers should begin with a thorough clinical history and physical examination, followed by laboratory tests to rule out underlying systemic conditions, and may include additional testing and specialist consultation as needed. The initial evaluation should focus on identifying potential triggers such as stress, trauma, nutritional deficiencies, or underlying systemic conditions 1. Laboratory tests should include complete blood count, iron studies (ferritin, iron, TIBC), vitamin B12, folate, and zinc levels to rule out nutritional deficiencies. Additional testing may include erythrocyte sedimentation rate and C-reactive protein to assess for inflammatory conditions. For recurrent or severe cases, consider screening for celiac disease with tissue transglutaminase antibodies, inflammatory bowel disease markers, and HIV testing when appropriate 1. Biopsy is generally not necessary for typical aphthous ulcers but may be warranted if the presentation is atypical or if there's suspicion of other conditions like oral lichen planus, pemphigus, or oral cancer. Some key points to consider in the workup include:

  • Detailed medical history to identify potential triggers and underlying conditions
  • Laboratory tests to rule out nutritional deficiencies and inflammatory conditions
  • Consideration of specialist consultation for systemic disease
  • Potential use of diagnostic treatments or biopsies for atypical presentations
  • Importance of individualized treatment approach based on patient's specific needs and disease severity 1. It is essential to prioritize the patient's quality of life and take a multidisciplinary approach to manage the condition effectively.

From the Research

Workup for Multiple Aphthous Ulcers

The workup for multiple aphthous ulcers involves a comprehensive approach to rule out systemic diseases and determine the underlying cause of the condition.

  • A complete history and physical examination are essential to identify any underlying systemic diseases that may be contributing to the development of aphthous ulcers 2.
  • The diagnosis of aphthous ulcers is primarily clinical, based on the characteristic appearance of the ulcers and the patient's medical history 3, 4.
  • Laboratory tests may be ordered to rule out systemic diseases such as autoimmune disorders, human immunodeficiency virus, infection, and hematologic or oncologic conditions 2, 3.
  • A differential diagnosis should be considered to rule out other conditions that may present with oral ulcers, such as gastro-intestinal diseases, nutritional deficiencies, and immune disorders 3, 4.

Differential Diagnosis

The differential diagnosis of aphthous ulcers includes:

  • Acute ulcers with abrupt onset and short duration, which may be due to trauma, bacterial infections, or deep fungal infection 3.
  • Recurrent ulcers, which may be due to postherpetic erythema multiforme or other conditions 3.
  • Chronic ulcers, which may be due to benign or malignant tumors, or drug-induced ulcers 3.
  • Systemic diseases such as Behçet's disease, which is a chronic, inflammatory disease characterized by recurrent bipolar aphthosis 3.

Treatment Approach

The treatment approach for multiple aphthous ulcers depends on the underlying cause and severity of the condition.

  • Topical treatments such as topical anesthetics, topical steroids, and sucralfate may be used to manage symptoms and promote healing 3, 4.
  • Systemic medications may be considered if topical therapy is ineffective or if the patient has a systemic disease that is contributing to the development of aphthous ulcers 4, 5.
  • A multidisciplinary treatment approach may be necessary to manage complex cases of aphthous ulcers, involving collaboration between medical practitioners and oral physicians 5.
