About the course

How the course will be conducted and what you will learn
During this seminar, we will delve into the complexities that dentists face during endodontic treatment and develop a clear algorithm that will help you determine the correct approaches and techniques in each situation.

We will start by studying the concepts of success and failure in endodontic treatment, comparing them to the concepts of implantology. We will examine modern classifications of success and conduct a detailed analysis of clinical cases.

Then, we will explore the causes of endodontic pathologies that arise after treatment and study mechanical and biological approaches. We will discuss intra-canal and extra-canal infections, errors in the treatment process, the impact of coronal sealing on prognosis and recommendations, as well as other factors that influence treatment success.
We will not overlook the forecasting of retreatments and present you with an author's solution scheme based on Fabio Gorni's research.
An important part of the course will be the discussion of apical surgery and its relationship to retreatment. We will examine the peculiarities of modern microsurgical procedures, their advantages and disadvantages, risks, and prognosis of the procedures. You will receive a biological rationale for decision-making and learn about the role of CBCT in treatment planning.

We will also introduce you to a clinical decision-making algorithm based on the Schätzle-Friedman scheme with author's additions.

As part of this course, we will also delve into the technical aspects of retreatment. You will learn about retreatment through the crown, the procedure for removing a crown/bridge (Metalift), and the removal of anchor pins, whether they are metal or fiber-reinforced. We will explore various clinical retreatment techniques, such as the use of gutta-percha, carrier-based gutta-percha (Termafil, Softcore), phosphate cement, resorcinol formalin, silver pins, pastes, and other materials. We will also discuss the necessary instruments, chemical preparations, and clinical nuances, providing you with examples and recommendations.

The next topic we will shed light on is broken instruments. I will offer you a clinical decision-making scheme based on several factors, such as tooth vitality, stage of canal cleaning, and the location of the broken instrument. You will learn about various methods of removing broken instruments and their detailed dissection.

In addition, we will provide you with an overview of ultrasonic devices and tips used in endodontics. You will learn about the principles of operation and application of devices such as Spartan (MTS) with CPR tips, EMS/Sybroendo (minipiezon) with RT1, RT2, RT3 tips, Satellec (P5, Newtron) with ET20, ET(D)40, ET25, K10/21/25, S04 tips, Osada (Enac) with ST17, ST21 tips, NSK (Varios) with E7, E6 tips, Proultra tips, B&L tips. We will discuss ultrasound techniques, clinical recommendations, and the compatibility of tip diameters.

And the final topic we will discuss is perforations. We will examine the modern classification of perforations, factors influencing prognosis, treatment methods, and the analysis of materials used for treatment, such as IRM, SuperEBA, MTA (ProRoot, MTA-Angelus, MM-MTA).

Throughout the course, we will not only cover all the aforementioned topics but also provide you with the comprehensive information necessary for successfully mastering endodontic practice. You will have access to relevant clinical examples, detailed analyses of each group of pathologies, as well as practical recommendations and modern treatment techniques.

Our goal is to help you develop the skills and knowledge that will enable you to effectively address the technical challenges associated with root canal retreatment. We strive to make your endodontic practice more successful and provide you with the tools to achieve high treatment outcomes.
Don't miss the opportunity to become an expert in endodontics and provide optimal treatment to your patients.

We look forward to seeing you in our course!

Course program

Mikhail Solomonov - course - endodontics
Concepts of Success and Failure in Endodontic Treatment
  • Comparison of success concepts in endodontics and implantology.
  • Modern classification (Healed, Healing, Disease).
  • Analysis of clinical cases.
Causes of endodontic pathologies after treatment. Mechanical and biological approaches.
  • Intraradicular infection.
  • Errors during treatment.
  • Coronal sealing in modern dentistry. Impact on prognosis, recommendations for re-treatment timing and materials for temporary fillings.
  • Extraradicular infection.
  • Trend or clinical reality?
  • Incorrect case selection.
  • Wrong diagnosis on the example of apical cemental dysplasia or cemento-osseous dysplasia.
  • Lack of orthopedic-periodontal evaluation.
  • Non-use of the Tracing procedure.
  • Foreign body granuloma (talk, cellulose, cholesterol).
  • True and pocket cysts.
  • Scar tissue.
  • Etiology, pathogenesis and prognosis of these conditions. Detailed analysis of each group.
Predicting healing outcomes based on Fabio Gorni's research, author's solution scheme.
Apical surgery and/or retreatment
  • Features of modern microsurgical procedures.
  • Advantages and disadvantages, risks and prognosis of procedures.
  • Biological rationale for decision making.
  • CBCT as a tool for treatment planning.
  • Healing peaks - traps for the clinician.
Algorithm of clinical decision-making
  • Based on the Schäfer and Friedman scheme with author's additions using data from the last decade.
  • Consideration of the main problematic groups in daily practice: Retreatment in the context of endodontic pathology. Retreatment as prevention of endodontic pathology.
Technical aspects of retreatment
  • Retreatment through the crown.
  • Removing crown/bridge (Metalift).
  • Removing anchor posts: metal and fiber-reinforced.
  • Removing cast post (Ultrasonic, Gonon extractor, Ruddle extractor, Masseran kit).
  • Retreatment clinical techniques: gutta-percha. Carrier-based gutta-percha (Termafil, Softcore). Phosphate cement. Resorcinol formalin. Silver posts. Pastes.
  • Instrumentation, chemical preparations, clinical nuances, and examples.
Broken instruments
The author proposes a clinical decision-making algorithm based on the following factors:

  • Is the tooth vital or infected?
  • Is the canal cleaning at an initial or final stage?
  • Was the instrument broken before or after the apical curve?

Based on this algorithm, the clinician can make a decision: attempt to remove the instrument, leave it in place, or attempt to bypass it (anatomical justifications for technical procedures).

A detailed description of methods for removing broken instruments.
