End to End: GI Tract Pathologies and their Oral Manifestations

Saturday, April 13

2 - 3:30 PM

1.5 CDE Credits – DDS, DH, DA


The gastrointestinal tract is one continuous tube originating with the oral cavity and terminating at the anus; therefore, it is logical that many conditions affecting the GI tract may have oral manifestations. This course will encompass a journey through the tract, beginning in the esophagus, examining gastroesophageal reflux disorder and its effects on the oral cavity. The final stops will be in the intestines with a synopsis of the inflammatory bowel diseases (Crohn’s and ulcerative colitis) and hereditary intestinal polyposis (Peutz Jegher’s syndrome). Cases from Ms. Lukes’ personal image collection will be presented with a lively discussion encouraging audience participation. Comparison images for inclusion in differential diagnoses will also be presented, urging dental professionals to utilize all patient information when analyzing lesions. Interdisciplinary and treatment strategies with be discussed for clinical practice applications.

Upon completion of the course the participant will:
- Discuss the importance of current oral/systemic pathology knowledge when conducting intra/extra-oral exams
- Explain the etiology, clinical appearance and treatment options of gastroesophageal reflux disorder, inflammatory bowel disease and hereditary intestinal polyposis
- Identify oral lesions as manifestations of systemic GI conditions
- Discuss interdisciplinary collaboration for follow up care for patients presenting with oral signs of systemic disease
