Course Description

Pathology of the oral mucosa entails a vast array of diseases that often confuse even the most experienced clinician. This course aims to use a “basic lesion” classification of oral mucosal pathology to help navigate and prioritize diagnosis and management of the patient.

Part 1: Red and White Lesions of the Oral Mucosa
“Redness” and ‘whiteness” are mainstays of clinical oral pathology. Utilizing these two parameters, separately and in combination, we will go through actual patient cases, ranging from the commonly encountered to the rare and/or complicated ones and discuss how to reach realistic, concrete decisions for the patient’s oral health care in clinical real time. Emphasis will be given on how to select appropriate diagnostic methodology and how to initiate and handle interdisciplinary communications where applicable for the patient’s condition. An update on treatment will be provided where it is useful to the dental practitioner.

Part 2: Ulcerative Oral Conditions
Oral ulcers or “sores “are among the most frequently encountered chief complaints in the dental practice. Using the characteristics of an ulcer (appearance, chronicity, pain, location and number of lesions) this part of the course prepares the clinician to systematically develop diagnostic assessment and treatment planning for a broad range of oral ulcerative conditions. Using clinical cases encountered in the largest oral medicine referral center in Michigan, we will present diagnostic decision trees and discuss which additional tests including tissue biopsy are necessary to arrive at a final diagnosis. Finally, we will provide therapeutic guidelines for common oral ulcerative conditions.

Learning Objective

At the conclusion of this course, participants will:

  • Document the clinical characteristics of common oral lesions accurately
  • Use lesional characteristics to form and prioritize a differential diagnosis list
  • Decide which diagnostic methodology(ies) is/are applicable and at what sequence they should be implemented
  • Decide on patient referral and initiate communication with other clinicians
  • Be familiar with and/or implement treatment based on accurate diagnosis of oral lesions
