Your regimen for aphthous ulcer

Recently, I had a consult about aphthous ulcers. This patient is immunocompromised because she is on chemotherapy from a hematologic malignancy. Despite the common incidence of this condition, there is no proven cure in medical literature. Medical treatment is directed towards alleviating symptoms, accelerating the healing process and prevention of recurrence. Commonly prescribed regimens include anti-fungal oral gels, anti-bacterial mouthwash, and nystatin mouthwash. In more complicated cases, clinicians commonly prescribe systemic steroids, topical anesthetics and immunomodulatory agents. However, there are other complimentary forms of treatment that are also effective such as gargling with a warm saline solution, direct application of salt on the lesion and ice chips. Which of these regimens do you usually recommend and what is the success rate based on your clinical experience?
