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.
The use of calcium silicate cements in non-vital immature teeth with pulp involvement
Treatment of young permanent teeth with pulp involvement is an endodontic and restorative challenge. The primary materials used in treatment have been calcium hydroxide, the original material of choice, and Mineral Trioxide Aggregate (MTA), the more recent material of choice. MTA is part of a class of materials known as calcium silicate cements or bioceramics, and has been used for pulp caps, pulpotomies and apical barriers. It has many favorable properties, but also some limitations, which include staining of dentine and a long setting time. New bioceramic materials have been developed to overcome these shortcomings. In this presentation, Marga Ree will present an overview of current calcium silicate materials, with an emphasis on their use in non-vital immature teeth. She will address the treatment options for non-vital teeth with open apices. Regenerative treatment approaches or revitalization is currently a “hot topic” in endodontics, and has been recommended as a promising alternative to the apical barrier technique, but there are still many limitations, not the least of which is an unpredictable outcome. In contrast, there is substantial evidence of a favorable outcome of immature teeth treated with the MTA barrier technique. Marga Ree will present numerous clinical cases with long-term follow-ups, which will illustrate her decision-making process and current treatment procedures, and make an argument as to why an apical barrier is often preferred over regenerative endodontics for teeth with open apices.
