The main goal for performing endodontic retreatments will be presented and the importance of intra-oral and intracoronal findings for endodontic therapy will be explained. In this lecture we will navigate through the various diagnostic, decision-making and technical aspects of endodontic (re)treatment. A structured sequence of diagnostics and therapy as well as the use of special aids that contribute to solving endodontic problems will be revisited.

Participation in this course 1.2 is a prerequisite for participation in the courses 2.2 and 3.2.

Perforations during endodontic treatments are often manageable today. In such cases, endodontists turn to the time-tested MTA, but why does this material work so well? Is every MTA always the same? Newer materials promise
easier handling and faster setting, but what is behind these claims, and do they really work just as well? What does the scientific evidence tell? The application of these materials can be challenging depending on the individual
situation. Which instruments are needed? The course will discuss the selection of the right material and teach
techniques for application in various clinical scenarios during the hands-on section. An overview and plenty of practical tips await you.

In the absence of microorganisms, the pulp shows good regenerative capacity when capped with materials indicated for vital pulp therapy (VPT) such as calcium silicate cements, e.g. MTA or Biodentine. The success rates of VPT
are independent of the age of the patient and the size of the pulp exposure. On the other hand, remaining caries, microorganisms and monomers from filling materials, have a negative influence on success rates, as these lead to inflammation of the tissue. According to current knowledge, VPT is indicated for teeth that only show symptoms of reversible pulpitis. In comparison, the evidence for VPT in teeth with irreversible pulpitis is still comparatively
limited. Nevertheless, partial and complete pulpotomy can be regarded as a valid treatment option for irreversible pulpitis and can certainly be considered as an alternative to vital extirpation. Nevertheless, success rates of approx. 80 per cent are realistic when using calcium silicate cements. In this lecture, the theoretical background to VPT and calcium silicate cements will first be explained. Subsequently, the sequence of procedures necessary to maximise the success of vital pulp treatment with calcium silicate cement will be shown. VPT from a clinical perspective and analyse a series of clinical
cases of increasing complexity will be discussed. In a final hands-on part, the VPT with a calcium silicate cement can be practised on special resin teeth.

A unique and special trauma model (Würzburg trauma benchtop model) will be used to discuss the appropriate procedure after dental trauma in acute cases, i.e. severe tooth fractures and dislocations. Using 3D-printed teeth, various scenarios will be simulated and numerous options for quick and easy emergency treatments will be tested, including practical splinting
options (when and how to use flexible or rigid wires or the titanium trauma splint). The participants will work and try out how the specific treatment steps, from tooth repositioning to adhesive fragment bonding, can be carried
out quickly and effectively. This workshop provides numerous helpful tips and tricks to improve participants skills in emergency dental traumatology management and treatment from splinting to the defect-free splint removal at the follow-up appointment.

Root canal calcification/obliteration is quite common in cases of chronic irritation of the pulp. Often, the tooth remains vital and further treatment is not necessary. However, sometimes the pulp becomes necrotic and apical periodontitis develops. When root canal treatment is necessary, it can be difficult to localise the root canal entrance and negotiate the root canal.
During this workshop, we will emphasise different ways to recognise the position of the original root canal. Using prepared CBCT images of an upper jaw with an incisor containing an obliterated root canal, the participants will be trained to design a printable guide with free software on their own laptop.

Recognising problems in conventional endodontic retreatment and taking them into account strategically when planning treatment is a skill that requires training and knowledge. The participants will use extracted teeth already treated to perform the exercises.

The prerequisite for participation in this course 2.2 is participation in courses 1.2 and 3.2.

Endodontology has undergone dynamic and fundamental changes over the past decades. Modern, evidence-based treatment concepts and their consistent implementation have led to significantly higher success rates. The continuing trend towards further training and specialisation as well as numerous material and technological developments, primarily the introduction of the surgical microscope, are decisive factors. At the same time, apical microsurgery has undergone a similar development and has also evolved from traditional apicoectomy, particularly by using the dental microscope and microsurgical instruments and materials specially developed for this purpose. This allows complex anatomical structures to be treated in a minimally invasive manner, which results in significantly higher success rates and more favourable healing processes. If orthograde root canal treatment fails and endodontic retreatment also fails or does not appear promising, microsurgical apicoectomy should be considered. The ongoing development of CBCT also closes an existing gap, both in preoperative X-ray diagnostics and in the planning of the microsurgical procedure.
The course aims to illuminate the range of indications, the significance and, above all, the clinical implementation of microsurgical apicoectomy.

Course contents:
- Etiology of apical periodontitis, indications and contraindications for apical microsurgery
- Preoperative diagnostics and treatment planning

Dealing with severely compromised/damaged teeth is part of dentist‘s daily routine. Whereas in the past such teeth usually had to be extracted, modern dentistry now offers a wide range of techniques which, if selected, combined and carried out correctly, can contribute to the successful preservation of a large number of teeth with severe loss of substance. Techniques for preserving vitality, endodontic treatment, subgingival restoration and prosthetic treatment are cross-linked, considering periodontal requirements. The course is intended to teach various techniques for tooth preservation and provide a clinical guide for a successful restoration of severely damaged teeth. Particular attention will be dedicated to the correct case selection, i.e. the question which teeth should be preserved and which should not. In a hands-on part at the end of the course, the techniques taught will be
practised.
Content:
- Surgical crown lengthening
- Magnet-extrusion as an alternative to crown lengthening
- Modern composite techniques for the restoration of severely compromised teeth
- Periodontal surgical strategies for tooth preservation
- Surgical defect visualisation for restorations and dental impressions
- Case selection and limitations
Hands-on:
- Proximal box elevation technique/proximal box elevation with composite

Endodontic treatments often present complex challenges, including the management of separated instruments within the root canal system. This workshop focuses on the techniques and strategies necessary for effectively bypassing and retrieving separated instruments to ensure successful treatment outcomes. Participants will gain hands-on experience in navigating various scenarios encountered in clinical practice, supported by the latest evidence-based approaches and technologies. The session will cover factors influencing the choice between bypassing or retrieval, practical techniques for safe instrument retrieval, and strategies to prevent further complications during endodontic procedures.

Learning objectives:
1. Understand the causes and risk factors leading to instrument separation in endodontic treatment.
2. Learn decision-making criteria for choosing between bypassing or retrieving separated instruments.
3. Master techniques for safely bypassing separated instruments to maintain root canal patency.
4. Develop skills in using ultrasonic and loop devices for instrument retrieval.

This workshop aims to provide participants with a comprehensive understanding of separated instrument management, preparing them to tackle these challenges confidently in their practice.

Participation in this course 2.5 is a prerequisite for participation in course 3.5.

Irrigation is an essential part of successful root canal treatment. All agitation and activation systems/devices aim at an effective removal of the intra-canal biofilm, debris and smear layer. Even if no particular method can claim to achieve better clinical healing success, as stated in the ESE guideline (European Society of Endodontology), laboratory studies have documented significantly better cleaning of root canal systems when activation is performed.

The workshop focusses on an enhanced root canal cleaning, debridement and disinfection using new technologies and/or new approaches for root canal irrigation and disinfection. The use of laser in endodontics is presented from its basics to the clinical application. Furthermore, participants will have the opportunity to test all common methods of agitation and/or activation in simulated, transparent root canal systems filled with artificial biofilm and to view the results directly (manual agitation, sonic and ultrasound-supported irrigation, laser, mechanical systems). Laser devices will be provided for clinical exercises.

The concept of minimally invasive dentistry is a fairly new concept, following the recent literature. This procedure aims to maximise the preservation of residual tooth structure, as it may be an effective way to reduce the
incidence of tooth fractures after treatment. However, other statements contextualise this aspect and emphasise that the main goal of endodontic treatment, sufficient chemo-mechanical preparation of the entire root canal system, is more challenging when using minimally invasive approaches.
Additionally, the technique requires specific and appropriate tools such as ultra-flexible instruments, visual magnification, superior illumination, and precise knowledge about tooth and root canal anatomy.
This workshop will give you an idea of the technical procedures of minimally invasive endodontics in different clinical situations, highlight their limitations and define how far minimally invasive clinicians should go to ensure gold standard endodontic treatments.
