Endodontic Misadventures: Diagnostic Challenges and the Element of Bias – Ep. 69

Guest: David Landwehr, D.D.S., M.S.

In this episode of Endo Voices, Dr. Marcus Johnson engages in a thought-provoking conversation with Dr. David Landwer, fellow of the American Academy of Oral and Maxillofacial pathology and endodontist, exploring the intricacies of diagnostic challenges within endodontics, with a particular emphasis on the pivotal role of Cone Beam Computed Tomography (CBCT) in differentiating between various lesion types. Dr. Landwehr underscores the necessity for a sophisticated and methodical approach to diagnosis, advocating for the refinement of clinical discernment to distinguish endodontic pathologies from non-endodontic conditions. He recounts a case involving a patient with osteomyelitis, illustrating how rapidly evolving clinical symptoms can lead to diagnostic ambiguity. Dr. Landwehr further stresses the importance of meticulous documentation of all findings, including incidental observations, not only to meet legal obligations but also to elevate the standard of patient care. Additionally, he emphasizes the critical role of transparent communication with both patients and referring clinicians.
