The lecturers

Dr.Marga Ree

Marga Ree, DDS, MSc obtained her degree in dentistry from the University of Amsterdam in 1979. For the next five years she was a part-time staff member of the department of Cariology Endodontology Pedodontology, as well as being a clinical instructor in the central dental clinic of the University of Amsterdam. In 1998 she entered a postgraduate programme in endodontics, which she completed in 2001 with a Master of Science degree. She is a popular speaker for dental and endodontic conferences, and has given over 200 presentations and hands-on courses in 30 countries all over the world. She is the primary author of several articles published in national and international journals and has contributed to several books on endodontics and restorative dentistry. Since 1980 she has had a private practice in Purmerend, which for the past nineteen years has been dedicated to endodontics.

Dr. Michiel de Cleen

Michiel de Cleen (1962) studied dentistry at the University of Amsterdam (NL). After his graduation in 1988 he served as an assistant clinical professor at the department of Cariology and Endodontology of ACTA (Amsterdam) until 1995. He is currently full time in private practice, limited to endodontics. Michiel de Cleen  is co-author of three Dutch textbooks on Endodontology and he has published extensively on all aspects of endontics.  He has  held several positions in the Netherlands Society for Endodontology (NVvE) and the European Society of Endodontology (ESE).

Dr. Michiel de Cleen

Longevity of the endodontically treated tooth

What do you answer when a patient asks how long his or her tooth will last after (successful) root canal treatment?

Read more

And what do you say if a tooth is lost only two years after root canal treatment? It’s all in the game?…. In this lecture, the focus is not on periapical healing, but on survival of endodontically treated teeth. It will be made clear that some teeth have a better prognosis than others. Emphasis will be put on those factors that positively influence long-term success, and on those factors that compromise such a result. After this lecture, which is supported with numerous clinical cases (some treated over 20 years ago), you will be able to inform your patients better on the benefits of endodontic treatment.


10.20 – 11.00

Dr. Marga Ree

How do we manage calcified canals?

One of the major causes of the failure of root canal treatment is the inability to localize and treat all of the canals of the root canal system.

Read more

The formation of secondary or tertiary dentin can result in blocking of canal orifices, and a significant amount of preparation of the pulpal floor might be required to locate them. Pulp canal obliteration may also be a sequelae of tooth trauma. How do we manage a yellow discoloration of a front tooth, when the canal is invisible on a radiograph?  Should we always perform endodontic treatment in such a case? What should be the size and extension of the endodontic access opening? In which situation can we safely remove dentin in an apical direction, and in which situation do we run the risk of creating a perforation?  Every clinician has been confronted with the dilemma: “should I give up or continue treatment with the risk of collateral damage?” In this presentation, various procedures will be addressed to identify hidden and calcified root canals and to make them accessible for instrumentation and disinfection.


11.00 – 11.40

BREAK


11.40 – 12.30

Dr. Michiel de Cleen

Fractured endodontic instruments: should we remove them?

With the introduction of rotary nickel-titanium instruments came a new problem: instrument fracture.

Read more

This lecture will deal with factors that cause instrument breakage, and with factors to minimize this risk. Not every fractured instrument may compromise the end result of our treatment. Michiel de Cleen will discuss when a fractured instrument may be left in the canal, and when such an instrument should be removed. The last part of the lecture will focus on instruments and techniques to safely remove a fractured reamer of file.


12.30 – 13.30

Lunch time


13.30 – 14.20

Dr. Marga Ree

Perforation repair

Root perforations are unfortunate complications to endodontic treatment and, if not detected and treated properly, may result in periodontal breakdown and ultimate loss of the tooth.

Read more

MTA is widely accepted as the preferred repair material for root perforations within bone. This bioactive material was the first bioceramic material introduced in endodontics in the mid-1990s. It has many favorable properties, but also some limitations. Efforts have been made to overcome these shortcomings with new bioceramic or hybrid materials. Despite similarities, the materials also have several differences that affect their mechanical properties such as setting time and compressive strength. In this presentation, case selection will be discussed in detail, as well as step-by step procedures to seal a perforation with an appropriate bioceramic material. Various clinical cases with follow-up will be discussed to illustrate decision making and current treatment procedures.


14.20 – 15.10

Dr. Michiel de Cleen

The endodontic-periodontal relationship – Current concepts and clinical implications

The endodontium and periodontium are separated only by a thin layer of dentine and cementum.

Read more

Because of this intricate relationship it may come as no surprise that infections of the endodontium influence periodontal health and vice versa. This lecture will focus on the differential diagnosis of lesions of endodontic and/or periodontal origin. Based on more than 25 years of clinical experience and recent research findings, guidelines will be presented to help the clinician in both diagnosis and treatment of combined endodontic-periodontal lesions.


15.10 – 15.30

BREAK


15.30 – 16.20

Dr. Marga Ree

Invasive cervical root resorption, preservation or extraction?

Invasive cervical resorption is a type of external resorption that is often not recognized during a routine dental examination.

Read more

Because the pulp may get involved only late in the process, this condition can be present for a long time without any signs or symptoms. ICR is often misdiagnosed as caries or internal resorption, resulting in improper treatment that may lead to premature loss of the tooth. Early detection is essential for successful management. In this presentation, clinical and radiographic features of ICR will be discussed, as well as possible etiological factors. In addition, a selection of clinical cases will be shown to discuss the decision-making process and management of ICR with emphasis on the restorative aspects of treatment.


16.20 – 16.30

DISSCUSSION

With the introduction of the operating microscope, predictable treatment options for solving complicated endodontic problems have improved significantly. Consequently, indications for apical surgery seem to have shifted somewhat in favour of nonsurgical root canal retreatment. However, the use of magnification and supportive armamentarium has benefited treatment procedures in periapical surgery as well. Endodontic surgery has evolved into endodontic microsurgery, a treatment modality that produces predictable outcomes in the healing of apical periodontitis. This 2-day course consists of a theoretical and a practical part. Theoretical classes are presented in an interactive manner. For the practical part, the participants have an array of state-of-the-art equipment at their disposal, e.g. operating microscopes, ultrasonic units, electro motors, microsurgical instruments and digital radio-graphy. We will practice on surgery models that have been specially developed for this purpose, and that closely mimic the clinical situation.
