All of the following are factors involved in the development of superficial fungal infections of the oral mucosa except

a. broad-spectrum antibiotics.
b. ill-fitting dentures.
c. immunocompromised patients.
d. open margin on a crown.

d. Superficial fungal infections of the oral mucosa occur primarily in:
• Immunocompromised individuals with xerotomia (e.g., HIV infection, cancer chemotherapy, organ transplants).
• In patients taking broad-spectrum antibiotics that affect a broad range of bacteria, allowing fungi to grow (taking acidophillus or yogurt may help to reduce the incidence of overgrowth of fungi while taking antibiotics).
• In patients taking inhaled steroids for asthma or allergic rhinitis.
• In patients with poorly fitting dentures (and are not immunocompromised).
