In this long-term, three-year case journey, Dr. Bill Nudera shares one of the most fascinating and educational cases of his career—an evolving diagnostic and therapeutic puzzle involving a persistent osseous defect in the maxillary right premolar region.

A challenging anterior case in which a necrotic tooth (#9) with a chronic apical abscess failed to resolve after an otherwise straightforward root canal treatment. When both sinus tracts remained unchanged at the 4-week follow-up, the case shifted from routine to complex, prompting a critical reassessment of next steps.

This is one of the most fascinating cases I’ve seen to date—a 13-year follow-up that reveals how treatment outcomes evolve over time. You won’t want to miss what happened with this case. Watch the full clinical tip to see the long-term results and what made this case so unique.
