The future - irrigants and irrigant agitation
Irrigation is an important part of root canal treatment and a very popular topic in the endodontic literature. Over the years, a vast amount of research and manufacturing efforts have been concentrated on the development of new irrigants and elaborate irrigation techniques, in order to supplement or even replace conventional syringe delivery of sodium hypochlorite. However, the best method to deliver and agitate the irrigant so that it reaches all the anatomic intricacies of the root canal system is still under debate and the ideal irrigant has yet to be found. Furthermore, modifications in the access cavity design and new instrumentation strategies bring additional challenges to root canal irrigation.
The aim of this lecture is to provide an overview of the current evidence on root canal irrigation and to discuss possible future directions.
1. Outline the main challenges for root canal irrigation.
2. Review the advantages and limitations of widely used irrigants and irrigant agitation methods.
3. Discuss emerging alternatives and possible future directions for research and clinical practice.

The future - supplementary methods of eliminating bacteria from root canals
Endodontic technologies and biomaterials have witnessed substantial advances in the last decade. In spite of these advances, some of the integral challenges in endodontic treatment continues to persist. Nanoparticle guided therapeutics that predictably disinfect the infected root canal system, reverse disease-mediated dentin matrix changes and regulate post-treatment healing have the potential to transform current concepts for a major paradigm shift in root canal treatment.
This lecture aims to cover the fundamentals and applications of engineered nanoparticles in the treatment of teeth with apical periodontitis.
• Will learn the basics of engineered bioactive nanoparticles
• Will learn the mechanisms by which engineered bioactive nanoparticles reverse disease-mediated dentin matrix changes
• Will learn the role of engineered bioactive nanoparticles in root canal disinfection

The future - root canal shaping
Root canal shaping with nickel-titanium rotary instruments is an important step of endodontic treatment to create space for delivering irrigants and subsequent obturation. Current NiTi systems allow shaping of even severely curved root canals with maintenance of the original path of the canal and procedural mishaps are less likely compared to stainless steel instruments. Shaping procedures should also aim to preserve radicular dentine and to retain structural strength, thereby preventing vertical root fractures and promoting long-term function of the tooth. This lecture will provide an overview of current shaping strategies and evaluate the effect of specific designs on shaping abilities and fracture resistance of root canal instruments. Finally, potential negative outcomes of instrumentation such as development of dentinal microcracks are discussed and an outlook on future trends for cleaning and shaping of the root canal system is presented.
This lecture aims to critically review the current literature on clinical procedures and instruments for root canal shaping.
1. Describe the basic concepts of root canal instrumentation
2. Evaluate the advantages and disadvantages of contemporary technologies and instruments
3. Discuss the potential risk of development of dentinal defects after root canal preparation
4. Present ideas of future techniques for root canal cleaning and shaping

The future - the optimum dimensions of the apical preparation
The main purposes of chemomechanical preparation are to clean, disinfect and shape the root canal. This can be regarded as the most important phase of the endodontic treatment, because instruments and irrigants promote the removal of bacteria and potential substrate from the main canal, which are the primary cause of apical periodontitis. The ideal size of apical preparation is one of the most controversial issues in Endodontics. Ideally, chemomechanical procedures should be considered complete when the canal is enlarged to instrument sizes that are compatible with the root anatomy and size, and sufficiently large to be safe and antibacterially effective. Microbiological studies have revealed that the larger the apical preparation size of infected canals, the greater the intracanal bacterial reduction. Studies have also shown that the larger the apical preparation size, the cleaner the apical canal. Larger preparations are also associated with improved outcome of the treatment of infected teeth with apical periodontitis. However, a great challenge for clinicians is to find a tradeoff between enlarging the canal suffiently to improve cleaning and disinfection, but not too much to avoid weakening the tooth structure. Strategies and perspectives for optimum apical preparation will be discussed.
To critically review the literature for the ideal dimensions of apical preparation and present future perspectives
1. Understand the importance of enlargement to achieve the goals of chemomechanical preparation;
2. Describe the scientific evidence about the effects of apical enlargement on root canal cleaning and disinfection;
3. Discuss the potential risks of large preparations;
4. Present perspectives for optimum apical preparation.

The future - NiTi alloys
Blue-Wire, Gold-Wire, M-Wire, R-Phase, T-Wire are these different alloys or just different names- or is it one NiTi alloy that has been heat treated differently? Manufacturers describe wordily - but at the same time give very little information about products. The Naval Ordnance Laboratory, which was closed in 1997, developed the fascinating Nitinol in 1958. The possibilities of using nickel titanium are far from being exhaustively tested. Not only in dentistry and aerospace or car industry new uses are being discovered until today.
The aim of the lecture is to shed some light on the facts, to separate assumptions from facts and to increase the basic understanding of rotary or reciprocating files used on daily basis.
For clinical application alloys are inevitably associated with heat treatment and geometry. In the lecture, existing file systems will be discussed and new perspectives on possible future developments will be given.
Present an overview of current alloys used in existing NiTi files and discuss future directions for alloy/instrument combinations.
1. To give an overview of existing combinations of alloys and instruments
2. Working out a sensible combination of alloy, geometry and field of application
3. To give an insight on future developments

The future - multiple or single cone canal filling
Lateral condensation of gutta-percha using multiple cones was the original obturation technique used when gutta-percha cones were developed, and it continues to be the primary technique taught to undergraduate students in dental schools in Europe and the United States. The single cone canal filling technique that uses only the master cone has gained popularity with the advent of nickel titanium rotary instrumentation systems, especially by employing larger cones with larger taper sizes that match the geometry of the rotary systems. The single cone technique does not require the use of accessory cones, thus reducing the time spent in root canal filling. This technique enables an easier and faster canal fill. However, aspects such as obturation quality, apical leakage and bacterial penetration of the single cone technique have generally been regard as similar to, or lower than other canal filling techniques. In the present presentation, the pros and cons of the two canal filling techniques will be reviewed. This will be followed by looking into the future, examining the possibility of futuristic single cone filling techniques that utilizes a material that expand with water sorption, and an experimental root canal sealer introduction technique that is inspired by the apical negative pressure technique utilized in root canal irrigation. Irrespective of any techniques to be adopted for future clinical use, it is important to emphasize the significance of material biocompatibility and durability. The audience will travel in the time channel from the future back to the past, and look at the two episodes in the history of endodontics that spanned over 10 years each, in which inadvertent canal filling material design had led to clinical problems that resulted in the retraction of the materials from the market.

The future - assessing residual tooth tissue for restoration
The relationship between endodontic treatment need, tooth restorability, endodontic outcome and tooth survival
The assessment of tooth restorability is a delicate decision-making process which includes a number of often neglected aspects.
In this lecture we will present the results of recently published and “in press” clinical trials assessing the effect of psychologic variables on the decision making on tooth restorability, the association between pulp preservation and tooth survival, and the effect of the residual volume of tooth structure on the survival of endodontically retreated teeth.
The final results of a retrospective trial on the ability of the Dental Practicality Index (DPI) developed by Dawood and Patel, to predict the survival of endodontically treated teeth will also be presented.
The aim of this lecture is to highlight common pitfalls in the assessment of tooth restorability and prediction of tooth survival and to help the clinician in making choices on tooth restorability and the need for root canal treatment based on clinical research data
The aim will be achieved by allowing the delegates to correlate the new findings
presented on tooth survival with published and in press Cone Beam Computed Tomography (CBCT) data on the outcome of endodontic treatment and pulp protection procedures
At the end of the lecture the delegates will also be familiar with the use of the DPI Index
