The core aims of endodontic treatment were to prevent and treat microbial contamination of pulps and root canal systems. We commonly used the terms "cleaning and sharing" to describe root canal treatment procedure. However, if we didn't have good shaping, we could not remove microorganism efficiently and the irrigant could not enter the root canal system to achieve good cleaning. Therefore, the purpose of this topic is to discuss how to do good mechanical shaping and match good chemical cleaning to achieve effective debridement and long-term prognosis in root treatment.
Vertical compaction technique of warm gutta-percha, described by Dr. Herbert Schilder in 1967, produces consistently dense, 3-dimensional root canal fillings, and has been developed to fill canal irregularities more effectively. While most clinicians should have a general understanding of the procedure, there are still some concepts that we may easily overlook or not fully clarify, which could potentially impact the outcome of the treatment. I hope this presentation can provide you with more inspiration and insights related to this technique.

Pulpotomies have traditionally been reserved for young patients, preferably with immature root apices, due to their increased pulpal blood flow, higher propensity for pulpal healing and desire for continued root development. However, advances in endodontic materials and our understandings of pulp biology over the past 20 years have allowed these conservative therapies to be applied as definitive treatments in mature teeth. Long-term prospective clinical studies and systematic reviews have shown these treatments possess good clinical and radiographic outcomes, with a recent systematic review showing an average clinical and radiographic success rate of 93.97% and 88.39% respectively at 3 years in patients presenting with irreversible pulpitis.
Bioceramics have proven critical to the success of pulpotomies as they demonstrate good sealing properties, excellent biocompatibility and favourable tissue response when placed in direct contact with pulp tissue, stimulating the release of growth factors that promote pulpal repair. Unfortunately, bioceramics currently available for pulp capping have setting times which might be considered long for day-to-day dental practice. Preparing these materials usually involve mixing powder to liquid manually or via trituration of capsules, which potentially results in increased preparation time, potential contamination during transfer and also wastage of material if too much is prepared. As such, for pulpotomies to be regarded as fast and predictable alternatives to RCTs, materials with similar if not better properties, including faster setting times and handling characteristics, are desirable. This lecture aims to summarise current and contemporary evidence for vital pulp therapy, focusing on material advancements for pulp capping. Findings from a clinical trial conducted at the National University Oral Health Centre Singapore using a novel fast-setting and premixed flowable calcium trisilicate cement for pulp-capping following pulpotomy in patients with reversible and irreversible pulpitis will also be shared.

The rationale for endodontic treatment is unarguably to eradicate the occurring infection and/or prevent microorganisms from infecting the root canal system. The microorganisms usually form biofilms so that have the ability to survive tough growth and environmental conditions. Therefore, endodontic disease is a biofilm-mediated infection, and the primary aim in the management of the pathological situation is the elimination of microbial biofilms formed on the root canal wall. There have been many attempts to remove biofilms effectively from the root canal system. Among these, over the past few decades, ultrasonically activated irrigation (UAI) is probably the most widely used supplementary method in root canal disinfection. A large body of evidence has shown that by inducing acoustic microstreaming and creating shear stress, UAI can improve the irrigant distribution as well as the physical disruption of bacterial aggregations.
Recently, a titanium oxide–coated heat-treated nickel-titanium irrigation file was introduced in the endodontic field. This instrument is known to have the potential to be used as a favorable UAI system regarding the removal of intracanal biofilms and medicaments according to previous studies. Here, this presentation describes several clinical strategies for the management of endodontic biofilms using the irrigation device. This lecture also highlights the novel 3D-printed root canal model that can be widely applied for various endodontic studies and shows evidence regarding the effectiveness of the instrument with the model.

The term minimally invasive endodontics has become very popular with the use of magnification methods and the modern endodontic devices that keep up with technological developments. An endodontic treatment with the maximum preservation of pericervical dentin is the most important goal of today's endodontics. The most important key to success in today's endodontics is to have knowledge and practice about the new methods determined in the access cavity preparation, the new generation NiTi rotary file systems used in the current root canal shaping procedures, the latest methods used in the activation of irrigation solutions, and the three-dimensional filling of root canals with new generation devices and materials. In this presentation, general information about the applications of minimally invasive endodontics will be given and the latest techniques will be explained in detail so that you will be able to perform in your dental clinic.

As a general practitioner, I do the root canal treatment and prosthodontic restoration by myself. Conventionally, after finalizing root canal treatment on a tooth, we either fill the cavity or access opening with a filling material or we cement a post and fabricate a full crown. Nowadays, with the improvement of the materials used in dentistry, especially lithium disilicate and zirconia, and the knowledge we newly acquired on adhesive bonding and fracture resistance, is it really necessary to prepare the endodontically treated tooth for a full coverage crown? Can adhesive dentistry replace full coverage crowns?

Three-dimensional root canal obturation is one of the key elements for a successful root canal treatment. Root canal obturation acts as a revealing mirror, reflecting the perfection of the process from the initial pulp chamber opening to the final root canal enlargement, cleaning and shaping. During the treatment, clinicians may overlook some details, which could accumulate like compound interest, ultimately leading to an imperfect root canal obturation. In recent years, the use of bioceramic sealers with the hydraulic condensation technique has gained popularity. CeraSeal is a new bioceramic sealer that offers excellent sealing ability, fluidity, and ease of operation. However, is this filling technique reliable? What are its advantages and disadvantages? What are the details of the operation? In this lecture, we will unveil the most popular root canal obturation method in recent years: the HYDRAULIC CONDENSATION technique. We will also incorporate numerous clinical cases using CeraSeal with gutta percha point as the filling material, helping you to gain a deeper understanding of how CeraSeal can improve your clinical work efficiency.

The sophistication for performing predictably successful root canal therapy has occurred through an interactive dynamics of advanced materials available, newer effective techniques and change in related biologic understanding and perspectives. With increase in number of cases reporting for endodontic therapy, dental professionals must deal with more complicated cases such as those with very fine and curved canals. Electrical discharge machine files (EDM) have revolutionized Endodontics by their extraordinary properties of flexibility and fracture resistance, which have begun a new era in Endodontics. This has reduced the number of files required for cleaning and shaping without having to compromise preservation of the root canal anatomy. This customized hands-on workshop shall focus on effective shaping and cleaning of highly curved canals with subsequent obturation and shall teach predictably successful endodontic techniques for management of highly curved canals that can be immediately implemented into clinical practice.

Untreated anatomy is the number one cause of failure of root canal treatment. We have modern files for preparing canals once they are located, but location of calcified canals still remains a huge challenge in endodontics. There are a number of techniques we can use to find calcified canals ranging from cone beam computed tomography (CBCT), use of modern microscopy, ergonomics and modern optics, as well as treated metal files, that can aid negotiation of these canals. This talk will cover techniques we can use to locate and negotiate calcified canals. A novel patency filing technique will also be described, where 2% tapered hand files can be minimized using greater tapered hand files. It will also discuss tools in our arsenal which make location and negotiation of root canals less stressful.

Abstract :

The present lecture will analyze the different possible clinical scenarios: first we will consider the 80-85% of the root canals in primary treatments, that may be defined as standard cases and may be easily shaped with a single-file basic preparation technique using only one reciprocating heat-treaded instrument; then it will be described how to clinically deal in a predictable, safe and efficient way the remaining 15-20% of the canals, that may be defined as complex, using different instruments, each one for every specific clinical situation. In fact, the use of a small reciprocating glide path file and the possibility to hybridize the techniques with a sequence of rotary files will also be described to solve those clinical cases with the most complex and particular root canal anatomies and achieve a minimally invasive root canal preparation.
