Lecture – Main Program
Modern disinfection of the root canal system
The root canal disinfection can nicely fit into the congress theme “Fact and Fantasy”. Before disinfection there is infection. The principles of endodontic infection should be understood, to perform an adequate disinfection. There has been much fantasizing about root canal infection and some false ideas have settled in the minds of clinicians. Central is the mistaken idea enterococci would be therapy-resistant germs, which are only eradicated by modern methods from the canal system. This presentation has the subject of infection and disinfection of the root canal system, with a critical look, to show that many (but not all) ways lead to a successful cleaning and disinfection.
