Course Description:

This course will teach all endodontic diagnoses accepted by the American Association of Endodontists and present the latest research on newly discovered advanced periapical lesions that adversely affect both teeth and implants. It will explain the biologic basis for endodontic disease progression and how symptoms, diagnosis, and treatments are interrelated. Advanced analysis of clinical, radiographic and historical findings will be introduced and emphasized in this course because once the pulp tissue loses form and function its response to infection may be eliminated, muted or unrecognizable. Calcification, ischemic pulp tissue, and partial pulp necrosis are the most common factors that alter test responses. This course will offer practical solutions to diagnose infections that do not elicit the typical symptoms.

Then we'll demonstrate how untreated endodontic infections advance outside the apex, and form lesions inside and/or outside their dentoalveolar sites. Although these lesions may appear stable, they often continue to advance through a variety of extensions. Similar lesions around implants will be shown as well. These newly discovered odontogenic and peri-implant extended lesions cause orofacial pain and/or treatment failure. Cases will be presented in 2D and 3D to show how these lesions prevent healing of non-surgical and surgical endodontic treatment, implants, extraction sites, and tissue grafts; but often present symptoms, if recognized, that reveal their exact location. The cases will demonstrate how accurate diagnosis and treatment of these lesions consistently results in both complete resolution of the infection and its associated pain, and the long-term retention of the involved teeth and implants.

Presented in 2D & 3D!

Course Objectives:

Participants in this course will gain knowledge in the following areas:


  1. Understand the accepted terminology of pulpal and periapical diagnosis

  2. Relate endodontic symptoms to the sites and extent of bacterial advancement

  3. Understand how endodontic diagnosis, symptoms and treatment are interrelated

  4. Understand how biofilms advance as extraosseous lesions and/or intramucosal lesions

  5. Understand the role of extended and complex lesions in treatment failure and orofacial pain

About the Speaker:

Dr. S. Craig Schneider received his endodontics specialty certification from the University of Pennsylvania, and his D.D.S. degree from the University of Maryland. He is a Lifetime Diplomate of the American Board of Endodontics and serves as an executive board member of the College of Diplomates. He was the first endodontist to become a Master of the Academy of General Dentistry, and the first to receive the AGD’s Lifetime Learning Service Recognition award. He received the honorary title of Master Dentist from the Maryland State Senate, and the ADA's Dentist Recognition Award. He maintains both a full-time practice limited to advanced endodontics and microsurgery in Columbia, MD, and a teaching position as a Clinical Assistant Professor in the Division of Endodontics at the University of Maryland School of Dentistry.

Dr. Schneider also conducts clinical research on advanced periradicular and peri-implant disease and has successfully treated over 1500 extended lesions since discovering them in 2009. He lectures both locally and nationally (including AAE18 and multiple endodontic residency programs). In 2021, the American Association of Endodontists (AAE) posted his research on their website (Endo OnDemand). He is scheduled to present his newest findings at AAE22 and the College of Diplomates’ 2022 summer conference.
