CE Credit: 1.0

Bioceramic calcium silicate-based sealers are the next generation of root canal obturation materials. As root-end filling materials, bioceramics have proven biocompatibility, osteoconductivity and excellent handling properties, but do they work as well as an obturation material? Hydrophilic in design, these sealers utilize moisture within the canal to complete the setting reaction. Do they actually bond to the dentin surface with no shrinkage upon setting? Can these materials easily be retreated? Using an evidence-based assessment, we will examine the chemical, physical and biologic properties and determine if we are ready to transition from gutta-percha to bioceramic obturation.

At the conclusion, participants should be able to:

  •  Describe the chemical, physical and biological properties of bioceramic obturation materials.
  •  Discuss the clinical and handling techniques for these new materials and the differences from traditional gutta-percha obturation.
  •  List the advantages and limitations of bioceramic obturation materials.

Michael S. Marmo, D.M.D.

Dr. Michael Marmo received both his DMD degree and advanced endodontic training at the University of Pennsylvania, School of Dental Medicine. He is active at Penn as a clinical associate professor where he instructs and lectures both endodontic residents and predoctoral dental students. One of his popular selective courses for the undergraduate program focuses on advanced techniques using nickel titanium rotary instruments. In addition, he maintains a private practice in Newtown, Pennsylvania. Dr. Marmo is a member of the Scientific Advisory Committee for The Journal of Endodontics, served on past AAE committees, and a Diplomate of the American Board of Endodontics.
