Clinical Endodontology was recently dominated by plenty of technical developments related to new equipment, modern tools and materials and innovative techniques in order to provide more comfort to the dentist in the treatment process. The crucial role of microbes and by-products of their metabolism in the development of apical periodontitis has been well-documented. Therefore, endodontic treatment should be considered as the clinical treatment of a microbial aetiology disease aiming to eliminate bacteria and prevent from re-infection. The achievement of those objectives requires thorough mechanical preparation, combined with appropriate irrigants, intracanal antiseptics and three-dimensional obturation of root canal system.

The aim of this course is the presentation and analysis of diagnostic and therapeutic problems related to Endodontics and familiarization of the dentist with the chemo-mechanical preparation and the three-dimensional obturation of the root canal system. In selected clinical cases, modern treatment protocols will be presented. Modern scientific data about specific fields in Endodontics will be reviewed through the analysis of these cases.

The diagnostic approach to pulpal and periapical disease is usually a complex process, that requires combination analysis of symptoms and radiographic findings. In particular, the diagnosis is based on data obtained from medical and dental history, responses to pulp sensibility tests and radiographic interpretation. Clinical examination and modern imaging techniques contribute significantly to the aforementioned goals. As part of this presentation, a brief reference to symptoms and signs of pulpal and periapical diseases and presentation of the modern classification of those diseases will be done.

A prerequisite of proper chemo-mechanical preparation and obturation of root canals is the knowledge of the morphology the root canal system of the tooth. With the development of modern research protocols, it is now evitable for the clinical dentist to display and analyze specific morphological characteristics of the root canal system of specific tooth types. Through the presentation of contemporary studies, concerns related to the number of root canals, the relationship between them, and the shape and location of root canal orifices will be analyzed.

Root canal preparation is of utmost interest. It is a process truly laborious, but also crucial for the successful completion of root canal treatment without iatrogenic complications.
Particular emphasis is placed on the use of rotary endodontic files, so that the clinician can perform adequately even in the most challenging morphologies. Clinical protocols of engine-driven endodontic file systems will be presented in detail, in order to provide the skill required for everyday use of rotary instrumentation.

Irrigation of the root canal system is a matter of daily clinical practice in endodontics. A variety of solutions and regimens have been proposed and investigated thoroughly. Yet, there are aspects of irrigation that are still described and taught mainly from empirical data. A modern approach to irrigants and irrigating techniques will be attempted via a scientifically based overview of the irrigation protocols during mechanical instrumentation. Issues regarding the activation of irrigation solutions, the removal of smear layer, and the use of chelating agents and protocols of final irrigation in Endodontics will be discussed.

Modern views on the techniques, materials and systems for three-dimensional obturation of system root canals will also be analyzed. Specifically, the aforementioned techniques may be classified into two categories:
1) techniques based on cold lateral condensation of gutta-percha points and
2) techniques based on warm vertical compaction of gutta-percha. It is necessary to know and use at least one warm technique in order to be used in appropriate cases.

It is essential not only to report and analyze these fields of the endontic science from a theoretical perspective, but also from the practical one, through clinical cases and practice course.

The participants must have with them extracted teeth from all tooth types in order to be well-trained even in more difficult and challenging cases.
