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

摘要

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. Thus, this in vitro study was designed to evaluate the efficiency of a new irrigation solution mixture of a tetracycline isomer, an acid, and a detergent (MTAD) (BioPure, Dentsply) containing a mixture of tetracycline (doxycycline hydrochloride), an acid (citric acid) and a detergent (Tween 80) in comparison with normal saline, 5% NaOCl and 17% ethylenediaminetetraacetic acid (EDTA) to remove intracanal smear layer.
