Recurrent Aphthous Ulceration: Epidemiology, Differential Diagnosis, and Therapy - L0740


About Course #L0740

Release Date: July 18, 2016

Expiration Date: December 31, 2019

Recurrent aphthous ulceration (RAU), also known as recurrent aphthous stomatitis and canker sores, is a common oral ulceration condition. RAU is widely considered to be a chronic inflammatory condition that affects approximately 20% of the population. These lesions tend to be episodic and may repeatedly arise over time in otherwise healthy individuals. RAU is a common lesion that presents to all clinical dentists. It is important for dentists to be knowledgeable concerning this pathologic condition in order to alleviate patients' concerns and pain.

This basic-level course is intended to educate dentists and dental hygienists regarding RAU so that they are better equipped to effectively diagnose and treat their patients with this condition. It is important to provide clinicians with necessary information regarding diagnosis (including differential diagnosis) and treatment. The section on etiopathology discusses the immune-relate etiology of RAU as well as the gaps in our understanding of what causes RAU. The course addresses the epidemiology and general characteristics of RAU and differentiates the forms of the condition. Research on the link between celiac disease and RAU is presented and discussed. Finally, the course presents information on the varied treatment modalities for RAU.
