Study Notes

Oral Medicine - 2

Oral mucosal ulcers are common, potentially reflecting a local or systemic cause.
A thorough clinical exam and history are crucial for diagnosis.
Complete loss of epithelium exposes underlying connective tissue (ulcer).
Partial loss of epithelium results in an erosion.
Common oral lesions include ulcers.
Ulcers can be a manifestation of numerous factors (local or systemic).
Clinical features aid diagnosis: number of lesions, location, and duration.
A single ulcer might indicate trauma, while multiple ulcers suggest recurring issues (e.g., stomatitis, herpes).
Location is significant (e.g., non-keratinized mucosa likely aphthous ulcer).
2-3+ weeks of ulceration may point to more severe causes.
Trauma-related ulcers can be thermal (e.g., maxillary/palatal gingiva), chemical (e.g., bleaching agents), or mechanical (e.g., dentures, parafunctional habits).

Clinical Features of Oral Ulcers

Number of lesions (single vs. multiple).
Location (keratinized vs. non-keratinized tissue).
Duration (> 2-3 weeks could indicate a more serious cause)

Local Causes

Trauma: thermal (e.g., hot foods), chemical (e.g., aspirin), and mechanical (e.g., ill-fitting dentures).
Parafunctional habits: overuse of teeth.
Poor denture fit.

Recurrent Aphthous Stomatitis (RAS)

Common oral condition.
Typically starts in childhood or adolescence.
Minor, major, or herpetiform types.
- Minor RAS is the most common type, characterized by small, round ulcers, <5mm, with a yellowish base and erythematous halo. Heals in 7-10 days. No scar.
- Major RAS is larger, >1 cm, occurs less frequently.
- Herpetiform ulcers are smaller (<5mm), multiple (frequently >10), and may coalesce.

Systemic Diseases

Some systemic diseases can manifest as oral ulcers (e.g., Behcet syndrome, HIV, etc)
Hematologic deficiencies, immunodeficiencies and other systemic diseases can cause ulceration as a symptom.
Some types of leukemia frequently include gum tissue enlargement, open sores in the mouth, and bleeding.

Infections

Viral infections (e.g., Herpes simplex virus, Coxsackievirus).
Bacterial infections (e.g., ANUG, syphilis, tuberculosis).

Drug-Induced Ulceration

Medications can cause oral ulcerations (e.g., cytotoxic drugs, NSAIDs).

Lichen Planus

An immunologically mediated mucocutaneous disorder.
Often appears as reticular, plaque-like, or erythematous lesions or patterns in the mouth.
Commonly affects the buccal mucosa, tongue, and gingiva.

Oral Lichen Planus

Affects buccal mucosa, tongue, and gingiva.
Possible malignant change, less than 1-3%.

Pemphigus and Pemphigoid

Similar autoimmune disorders, but differ in blistering locations.
- Pemphigus presents with intraepithelial blistering (intraepithelial separation from skin or mucous)
- Pemphigoid is subepithelial blistering (usually affects the skin and mucosal surfaces.

Erythema Multiform

Characterized by painful oral ulcers.
Can be triggered by infections or medications like NSAIDS.

Malignant Neoplasms

Oral cancers and lymphomas can present as persistent non-healing ulcers with irregular borders.

Other

Other potential causes for oral ulceration include lupus erythematosus, chronic inflammatory diseases, etc.
