Seminar Topic: Treatment of Post Endodontic Disease
Speaker: Dr. Sam Kratchman
The retreatment of root canal failures provides unique challenges. Many times, the canal has been transported and/or the survivability of the tooth is jeopardized due to the removal of excessive amounts of dentin during the original root canal procedure. Procedural mishaps, especially perforation, can present a particular challenge. Successful treatment requires a thorough understanding of the causes of failure, the prognosis of each possible approach to treatment, and technologies and materials that allow us the best possibility of biologic success as well as maximum potential for survivability of the tooth. This presentation will discuss the causes of failure and the theoretical strategies for success. New technologies will be presented that allow us to disinfect the canal maximally with minimal destruction of the remaining tooth structure. Where retreatment is deemed to be too dangerous or the prognosis is not good enough, surgical approaches with new bioceramic root repair materials will be discussed.
