Diagnosis drives dentistry! Hence, in order to provide the appropriate treatment, clinicians must be able to diagnose the patient’s presenting condition. This in turn implies that clinicians must have a thorough understanding of the various conditions that occur and how they progress through their different stages. Unfortunately, pulp, root canal and peri-radicular conditions are not well understood. This is largely due to poor and inconsistent terminology that is seen in the literature as well as in day-to-day practice. The poor terminology that has been advocated in the last 10-15 years in itself demonstrates the lack of understanding of these conditions by those who proposed, and use, these inappropriate terms. Once the diseases are understood, the diagnostic process becomes more meaningful and easier. The diagnosis still requires a thorough examination with the application of all relevant diagnostic tests, plus an understanding of what information the various tests are telling us. In particular, pulp sensibility tests, percussion, palpation and transillumination are often not adequately utilized or interpreted correctly and so important information may not be available to establish the diagnosis. This presentation will provide a simple overview of the disease processes with emphasis on the various symptoms and clinical signs that lead to correct and meaningful diagnoses using appropriate terminology. Guidelines for effective and reliable diagnostic testing under different circumstances will also be outlined since the best test depends on what you are trying to diagnose. Research by the lecturer’s group has clearly demonstrated that the use of appropriate terminology is more likely to lead to appropriate treatment, and such terminology should not be based on the presence or absence of symptoms. More comprehensive terminology should be used. The lecture will demonstrate that words do matter!

The discovery of dental stem cells (DSCs) in the 2000s has promoted the research interest in not only the characterization of these stem cells but also their applications in regenerative medicine. Along with the advancement of tissue engineering research, these DSCs have been tested for regeneration of various dental and oral tissues such as pulp, dentin, cementum, periodontal ligament (PDL) and bone. DSCs are highly angiogenic and neurogenic and can be reprogrammed into induced pluripotent stem cells (iPSCs) that possess a tremendous wide range of biomedical applications. There are at least six types of DSCs from human teeth that have been isolated and characterized, including dental pulp stem cells from pulp of permanent or deciduous teeth, PDL stem cells, stem cells from apical papilla, dental follicle stem cells and gingival mesenchymal stem cells. The emergence of regenerative endodontics has been in part influenced by the discovery of these DSCs. There are two categories of clinical approaches to regain the vitality of pulp. One is stem-cell based therapy that involves implanting exogenously processed stem cells into the root canal space, termed cell-based regenerative endodontic therapy (CB-RET). This approach has shown the regeneration of pulp- and dentin-like tissues in the canal space from animal and human clinical trial studies, suggesting potential practice of true “regenerative endodontics” in the future. On the other hand, revitalization or also termed revascularization, that does not involve the delivery of exogenously processed stem cells into the canals therefore is termed cell-free regenerative endodontic therapy (CF-RET). The various animal and human clinical studies have shown that the tissues developed in CF-RETs are fibrous connective tissue, some resembling periodontal ligament, not pulp-like, and the mineral tissue as cementum-like or bone, not dentin-like. Despite this drawback, CF-RET increases root thickness and eliminates endodontic pathosis with high clinical success rates.

Outcome refers to the actual result of a patient’s condition due to their disease or following a specific intervention, with outcome measures including survival rates and success rates. Meanwhile, prognosis is a medical term that considers information from previous outcomes to anticipate the future developments of a patient’s condition and the likelihood of success following an intervention. Having a comprehensive understanding of the factors that influence treatment outcomes is important in endodontics, enabling providers to consider patient and tooth conditions and select procedures that are predicted to maximize tooth survival and minimize postoperative complications. The upcoming course will cover the factors that influence the outcomes of different endodontic treatments, such as primary root canal treatments for both vital and necrotic teeth, non-surgical and surgical re-treatments, and treatments for cracked teeth. This course will emphasize the importance of considering patient-, tooth-, and procedure-related factors as prognostic indicators before developing a treatment plan, with the ultimate goal of enhancing tooth durability and ensuring patient satisfaction. Learning objectives: 1) Explore various success measures, such as tooth survival, postoperative pain, and evidence of apical radiolucency. These measures will be used to delve into multiple prognostic factors that significantly impact the outcomes of the following endodontic treatments: .Primary root canal treatments for both vital and necrotic teeth .Non-surgical re-treatments .Surgical re-treatment .Cracked tooth treatments 2) Evaluate the potency of patient-, tooth- and treatment-related factors in determining the overall success and survival rates of teeth treated through endodontics. 3) Consider these prognostic factors to design a roadmap for endodontic treatment planning that maximizes the success and survival rates of teeth.

The diagnosis and treatment of dental pain is fundamental to the practice of Endodontics. However, the experience of pain is complex with biological, psychosocial, and affective components, which means there can be a disconnect between the experience of pain in a patient, and the presence of clinical disease. Teeth are uniquely innervated and cause severe pain and sensitization of the nervous system, even in the absence of pathological infection. Persistent pain can occur even after successful endodontic treatment, due to changes in the nervous system that has been triggered by the original injury to the pulp. Endodontic materials, including sealers can cause injury and inflammation to nervous tissues, further complicating the clinical picture. Understanding the mechanisms by which these materials interact with the nervous system is crucial for successful treatment outcomes. In this presentation, we will discuss recent data describing the effects of different classes of Endodontic sealers on sensory neurons, diagnostic dilemmas related to pain, clinical strategies for when pain doesn’t go away after Endodontic treatment.

The prognostic data about Endodontic Microsurgery attests to the fact that microsurgical success rates are far superior to traditional surgery. At the same time, within the surgical technique, each step of the procedure is important to ensure successful outcome. Incorporating microsurgical principles, the success rate of endodontic microsurgery has been reported to be approximately 90%. This presentation is based on a 20-year clinical study of microsurgery at the Microscope Center, Department of Conservative Dentistry of Yonsei University, Korea, since 2001. It will critically review the short-term and long-term outcomes of endodontic microsurgery as well as the outcome of micro re-surgery. In our study 192 teeth were followed up every 6 months for 2 years and every year up to 10 years. Over the 5-year period, 172 teeth (91.5%) were successes. The teeth classified as successes were evaluated up to 10 years, with a final follow-up rate of 60.5% (104 of 172 cases). Out of 104 followed-up cases, 97 cases were classified as success in the long term: 91 with complete healing and 6 with incomplete healing. The overall maintained success rate was 93.3%. Regarding micro re-surgery, 54 teeth requiring surgical retreatment were studied. 39 teeth (92.9%) had successful outcomes. This lecture will also deal with the prognostic factors for clinical outcomes in microsurgery based on our clinical studies, especially periodontal involvement, bony defect and lesion size. The healing success rates of endodontic microsurgery will be compared for cases with lesions of endodontic origin and with cases of combined endodontic-periodontal origin. Effects of bone tissue deficiency and lesion size on the outcome will be discussed based on clinical studies of intraoperative measurements of bone defects and 3-dimentional analyses using cone-beam computed tomography.

Root canal obturation is a critical step in endodontic treatment, as it involves the complete filling of the root canal system with an inert material to prevent bacterial reinfection and promote healing. Appropriate root canal obturation can ensure the aseptic and long-term success of endodontic treatment. The essential concepts of obturation include the use of a biocompatible, dimensionally stable material that can be easily manipulated and adapted to the canal space. Historically, gutta-percha has been the material of choice for obturation, with the use of sealers to enhance its sealing ability. At that time, gutta percha was preferred over poor quality root canal sealers, which would shrink and wash out over time, leaving a gap. Thus, compaction techniques aimed to replace the soluble sealer with the insoluble gutta percha. However, the recent development of a new generation of sealers with superior properties, such as bioceramic sealer, has called into question the axiom of minimizing the sealer interface. The bioceramic sealer is dimensionally stable, non-soluble, biocompatible, antibacterial, hydrophilic, and can bond to dentin, indicating a new era of endodontic obturation. Minimal invasive endodontics is a concept that emphasizes the preservation of healthy tooth structure during root canal treatment, while still achieving optimal cleaning, shaping, and obturation of the root canal system. Hydraulic condensation with bioceramic sealer may be a novel evolution of root canal obturation. This presentation provides an overview of the essential concepts of root canal obturation, the vertical compaction of warm gutta percha technique including the thermal profiles of different gutta percha, the indication of different obturation technique and materials and highlights the recent advancements in materials and techniques that have improved the quality and success of endodontic treatment.

Young permanent teeth are susceptible to pulp diseases due to rapid caries progression, facilitated by their high pulp horn and immature mineralization. However, conventional root canal treatment becomes challenging due to the short roots, thin dentin walls, and open root apices commonly found in these teeth. Therefore, vital pulp therapy and regenerative endodontic procedures using tissue engineering principles offer the best treatment options for young permanent teeth. These approaches aim to maintain root development, promote the formation of thick dentin walls, and achieve normal root length. Several factors need to be considered when determining the appropriate endodontic treatment for young permanent teeth. In cases of pulp diseases caused by caries, accurate pulp diagnosis, effective infection control, and thorough cleaning of the remaining pulp tissue or canal space are crucial for successful treatment outcomes. The application of calcium silicate biomaterials, such as mineral trioxide aggregate (MTA) or Biodentine, is recommended. However, in situations involving trauma-induced pulp diseases, factors such as crown or root structure damage and potential pulp tissue damage resulting from tooth displacement should be taken into account. In some instances, young permanent teeth may present root crack with persistent infections that cannot be controlled non-surgically. In such cases, intentional replantation or apical surgery with Biodentine retrograde filling may be considered as alternative treatment options. Overall, understanding the unique challenges associated with treating young permanent teeth and considering the specific clinical circumstances are essential for selecting the most suitable endodontic interventions. By following these principles, clinicians can navigate the complexities and achieve favorable treatment outcomes for their young patients.

In the past 30 years, the revolutionary development of incorporating nickel-titanium (NiTi) into endodontic files has greatly transformed the methods of root canal instrumentation. The unique material properties make them particularly suited for endodontic treatment. However, there are still a lot of problems demanding solutions till now. Instruments separation and surface blunt after repeated uses are the most concerned problems among them. The two main reasons of unexpected separation of NiTi endodontic instruments are the cyclic fatigue and the torsional overloads. As results, manufacturers made a great effort to find out any parameters that directly or indirectly influence mechanical properties of NiTi rotary instruments. The mechanical performance of NiTi alloys is according to their microstructure and associated thermomechanical treatment history. Heat treatment is one of the most fundamental approaches toward adjusting the transition temperature in NiTi alloy, which affects the fatigue resistance of NiTi rotary instruments. The newly developed NiTi instruments made from the next generation of NiTi alloys represent improved flexibility and better fatigue resistance. The special thermomechanical processing is a metallurgical process that integrates hardening and heat treatment into a single process. Although the details of the thermomechanical treatment history of the new NiTi wires remain unknown, it seems that thermal processing is a very hopeful method of gaining important benefits with regards to the efficiency and safety of NiTi rotary instruments.

Currently, Endodontics is facing outstanding innovative advancements in diagnosis, and clinical interventions to achieve more sustainable outcomes both for practitioners and the patients. Vital pulp therapy and regenerative endodontic procedures are the most important ones. VPT as a dedicated therapeutic method is targeting pulpal tissue conservation, protection, and maintenance when compromised by different causes. Respecting the inherent capacity of dental pulp to repair actively, VPT seems to be more practical and successful contemporarily based on higher chances of case selection, new biomaterials availability, easier ways of follow ups and also modalities attainable to overcome shortcomings and failed cases if any. As it is needed to extent knowledge and experience of pulp biology, physiology, microbiology, caries progression, dental materials, the aim of this presentation is to provide the last information released on classification, indications, challenges encountered, and modalities to qualify and improve the techniques. Hopefully evidence-based endodontics would help us to reach the best outcomes in case of vital pulp therapy.

This presentation will highlight the use of Cone Beam Computed Tomography (CBCT) information in decision making for diagnosis, treatment options and recommendations, and assessments of post-treatment outcomes. Cases will be used to demonstrate how CBCT has strongly influenced endodontic practice. Additionally, CBCT can aid in the differentiation and management of endodontic failure and failure of endodontically treated teeth. This presentation will describe the difference between these two types of treatment failure. Participants will learn how to provide an appropriate endodontic clinical examination, assess radiographic images of endodontically treated teeth, including CBCT images. Discussion will include how this information will inform your diagnosis and treatment planning decisions, in order to provide patients with treatment options.

The aim of endodontic treatment is to prevent or cure apical periodontitis. Root canal treatment is a predictable procedure with a high survival rate. However, procedural problems such as broken instruments, ledge formation, transportation of the canal, root perforation, and extrusion of the irrigants can affect the prognosis. On the other hand, patients demand the retention of their teeth more than ever before, and this results in an increasing necessity for the procedure. Retreatment is easier with the help of Ni-Tis, irrigation systems, biomaterials, and ultrasonic instruments. Even hopeless teeth can be saved. There is no doubt that both root canal treatment and retreatment of teeth are feasible and economical ways to preserve function. In this lecture, factors that affect the outcome of retreatment will be discussed based on literature and presented cases

Vital pulp therapy aims to maintain the vitality of dental pulp tissue by stimulating tertiary dentin formation. Current materials used in clinical treatment still have several drawbacks due to their physical and biological properties. Innovative materials containing bioactive molecules have been introduced to facilitate dentin/pulp complex regeneration. Among current materials for vital pulp therapy, calcium silicate-based materials exhibited better biocompatibility, differentiation induction, and reparative dentin formation in vitro and in vivo. Dental pulp tissues exposed to calcium silicate-based materials markedly enhanced Wnt signaling activation. The Wnt agonist and ligands enhanced reparative dentin formation in vivo. Mechanistically, Wnt signaling modulated inflammation and immune responses and promoted odontogenic differentiation. In addition, Wnt interacted with Notch signaling to control odontogenic differentiation and mineralization. In another aspect, decellularized extracellular matrix derived from human dental pulp stem cells induced mineralization by activated Wnt signaling. This evidence suggests that Wnt signaling modulation represents a promising strategy for vital pulp therapy and the regenerative approach of the dentin/pulp complex.

Cone beam computed tomography (CBCT) has become an indispensable radiographic modality for dentists, providing high-quality, accurate three-dimensional (3D) representations of maxillofacial structures. The development of CBCT has highlighted the inadequacies of conventional radiography which are compression of three-dimensional anatomy, geometric distortion, and anatomical noise Needless to state, clinicians should have a thorough knowledge of CBCT before prescribing/using it for patients. This lecture will discuss the applications, advantages, and disadvantages of CBCT in endodontics. A variety of clinical cases will be presented to the audience to provide a holistic understanding of CBCT in Endodontics.

Vital pulp treatment (VPT) is a therapeutic strategy aimed at conservatively managing deep carious lesions and the exposed pulp. VPT has recently expanded through the use of hydraulic-calcium-silicate cement, cone-beam CT, and dental operating microscopy (DOM), as well as an improved understanding of pulpal biology and repair mechanisms. It is widely accepted that the treatment strategy for irreversible pulpitis is pulpectomy. Recently, some reports demonstrated that partial or cervical pulpotomy may be a feasible option for the treatment of irreversible pulpitis. Regarding to how to treat the deep caries or the exposed pulp, consensus documents from American Association of Endodontics and The European Society of Endodontology are available for our clinical treatment. However, despite the positive opinion of VPT as a strategy for irreversible pulpitis, the idea is not widespread generally, even in Europe and the United States. The factors for this include the difficulty of dental pulp diagnosis and the lack of a consistent teaching education for handling exposed pulp. In this symposium, I will show several cases related to VPT with dental operating microscopic video. These case series included successfully in preserving the activity of the pulp by partial pulpotomy caries induce pulpal micro abscess. Here we also discuss dressing agent and material induce pulpal repair the exposed pulp. There may be restrictions depending on the circumstances of each country and available dental materials, but it may lead to new discoveries. Additionally, we will find and discuss the current issues to be solved of VPT and introduce our department's research to solve them.

Iatrogenic root perforation is a complication that can occur during endodontic treatment. It is a significant problem for the tooth integrity as it can lead to inflammation, infection and ultimately tooth loss. Despite the potential complications, the prognosis for iatrogenic root perforation is generally favorable with appropriate management. The clinical management of iatrogenic perforation depends on the location and size of the perforation as well as the severity of the damaged caused along with-it proper communication with the patient is of utmost importance. Treatment options include sealing of the perforation site with biomaterial non surgically or surgically depending upon the access to the site, degree of contamination and the condition of the surrounding tissues. The outcome depends on several factors, including the extent of injury, the patient’s overall health and the timely and appropriate management of the perforation. This presentation will explore various clinical condition of iatrogenic root perforation, its management with various biomaterials and its outcome assessed clinically and radiographically.

The success of root canal treatment depends on the complete removal of infected microbial content from the root canal system. Today, with the development of nickel-titanium rotary file systems, root canal shaping has become quite simple and fast. Despite mechanical reduction of the bacterial population, it is not possible to eliminate the whole bacteria and root canal debris without the use of antibacterial solutions and activation systems from the root canals. New technology makes it possible to clean the root canal space without damaging tooth structure. In this presentation, characteristics of known and developing root canal irrigation agents and irrigation activation methods will be evaluated under the light of current literature information.

“Palatal Root-end Endodontic Surgery (PRES)” involves the root-end resection and root-end filling of the palatal root of a maxillary molar and can be one of the most challenging procedures in endodontics. While the transantral approach for PRES and 3D navigated PRES have been advocated, there are cases that are not amenable to transantral PRES or 3D navigated PRES due to anatomic variations therefore it is necessary for clinicians to be knowledgeable in the traditional PRES approach. In this presentation, I will cover the anatomical, technical, and decision-making aspects of PRES.

At the conclusion, participants should be able to:
1.Identify key anatomical landmarks including the greater palatine foramen, spine, and grooves in order to locate the greater palatine artery and nerve in relation to PRES.
2.Design the appropriate flap to provide strategic access to the palatal root apex in order to facilitate the root-end resection and root-end preparation and filling.
3.Describe a novel modified continuous sling-mattress suture technique.

The success of root canal treatment depends on accurate diagnosis, effective treatment planning, and overcoming the challenges of root canal anatomy. Digital endodontics, which combines modern tools, is increasingly being used for complex cases. Artificial intelligence interpretation of Laser Doppler provides precise diagnosis, while advances in CBCT equipment and software render true internal anatomy visible. With 3D planning, guided endodontics has become a viable option. These tools are applied at different stages of endodontic treatment, with specific indications and clinical efficacy. Digitally guided endodontics is a precise, effective, safe, and clinically applicable strategy that integrates technical resources and digital planning into clinical endodontic practice. Overall, these techniques represent a significant advancement in the field of endodontics, with potential for revolutionizing the way we approach complex cases.

In recent years, digital dentistry has experienced significant growth and development, which is no exception in the field of endodontics. CBCT and oral scans are widely used in dental implantation and prosthetics. In the field of endodontics, CBCT, and oral scans can be used to perform Guided Endodontics, also known as Static Navigation. Additionally, Stereotactic technology is utilized in Dynamic Endodontic Navigation. Both Static and Dynamic Navigation utilize digital technology to more accurately locate the position of root canals or root apex, to achieve precise endodontic treatment results. This presentation will review this topic and present examples of clinical applications.
