Course Description

Ulcers, though common in the mouth, are difficult to diagnose and treat. Oral ulcers can present alone or in multiples; they can be round and well defined with pseudo membrane in the center, or they can be irregular and feature generalized sloughing. Dental practitioners are familiar with the problem of having patients with sloughing epithelial disease or chronic recurring ulcers that do not respond well to numerous treatments. There is no simple solution to this problem. Nevertheless, this course aims to systematically analyze what we know about oral ulcers and sloughing epithelium with the goal of unpacking possible etiologies. The course will cover chronic immune diseases such as lichen planus, lichenoid mucositis, mucous membrane pemphigoid and pemphigus vulgaris. It will also examine contact hypersensitivity reactions, especially to restorative dental material and to cinnamon. Blistering viral diseases such as those in the herpes simplex family and coxsacki family will be covered, as well as nutritional and oral manifestations of systemic diseases. Vitamin B and iron deficiency will be discussed as possible causes of these conditions. The course will also discuss a number of systemic diseases that can present, sometimes at first presentation, with oral superficial ulcers—including Crohn’s disease and Behcet’s disease.

Course Objectives

As a result of attending this course, you will be able to:

  • Develop an applied differential diagnosis for multiple oral ulcers and sloughing epithelium
  • Identify chronic immune diseases affecting the mouth
  • Recognize the oral manifestations of systemic diseases such as Crohn’s disease
  • Assess blistering viral infections of the mouth
  • Determine the role of Immunofluorescence in diagnosing chronic immune diseases
  • Evaluate the role of restorative material in causing generalized oral ulcers
  • Consider the role of vitamin B and iron in the growth and development of oral epithelium
