Updating Diagnostic Terminology in Endodontics
A Collaborative Proposal by the AAE and ESE
About This Initiative
The American Association of Endodontists (AAE) and the European Society of Endodontology (ESE) have jointly launched an initiative to update endodontic diagnostic terminology. This project builds on the 2009 classification published in the Journal of Endodontics and reflects the latest advancements in vital pulp therapy, diagnostic imaging, and our evolving understanding of pulpal and periapical disease.
Since July 2023, a Joint Special Committee composed of expert representatives from both organizations has worked intensively to develop an updated diagnostic classification framework. This includes two tables intended to be used in tandem, as part of a comprehensive clinical diagnosis in endodontic practice. Please view a background statement from the committee as well as proposed tables at the links below:
Why This Matters
An accurate, contemporary diagnostic language is essential for:
- Improving clinical communication
- Enhancing educational resources
- Supporting research standardization
- Ensuring consistent reporting of clinical conditions
Yet despite advances in technologies like CBCT and improved outcomes from vital pulp therapies, there remain significant limitations in commercially available diagnostic tools and persistent gaps in clinical knowledge. These realities shaped the development of this classification—and reinforce the importance of broad-based input.
We Need Your Feedback
We are now entering a stakeholder review phase to ensure that the proposed terminology is robust, relevant, and clinically useful. We invite feedback from a wide range of stakeholders, including practitioners, dental organizations, educators and researchers, patients and others.
Your input will help refine, validate, and finalize the proposed classification system. All responses will be considered by the Special Committee as part of their revision and finalization process.
How to Participate
Please take a moment to review the proposed diagnostic terms and definitions, then submit your feedback via the online form.
Additionally, a hearing will be held at the European Society of Endodontology Biennial Congress in Paris, France, on September 3, 2025. Please review the following guidelines to participate.
