Comparative evaluation of a new endodontic irrigant - mixture of a tetracycline isomer, an Acid, and a detergent to remove the intracanal smear layer: a scanning electron microscopic study.

Background: The most important and demanding aspect of endodontic therapy is considered to be cleaning and shaping. Irrigation is considered a vital adjunct to instrumentation of the root canal for canal debridement. Until date, there is no single solution that simultaneously removes the smear layer and disinfects the entire root canal system.
