Microleakage of Endodontic Temporary Restorative Materials under Dynamic Loading

During endodontic treatment, it is important to create a fluid-tight seal in the access cavity in order to prevent marginal leakage and the ingress of oral fluids and microorganisms into the root canal. Nevertheless, temporary filling materials have received less attention than materials used for a permanent and prolonged use. However, they are an essential link in the chain that leads to disinfecting and preventing contamination or recontamination of the root canals. Numerous methods have been described to determine the sealing ability of endodontic temporary restorative materials. Beside dye penetration tests, autoradiography, electrochemical methods, fluid filtration techniques, and bacterial penetration tests have been applied to determine microleakage. Among these methods, dye penetration tests are the most popular method for studying microleakage because they are easy to conduct. In most of the previous studies regarding microleakage, specimens were placed in a dye Microleakage of Endodontic Temporary Restorative Materials under Dynamic Loading
