Sterilization is a process that eliminates or kills all microbes, including transmissible agents present on a surface, contained in a fluid, medication or biological culture media (UCLA Department Epidemiology). Dry heat sterilization is one of the important methods of eliminating microbes, as it coagulates the proteins in an organism, Conclusion: It appears dry heat sterilization increases stiffness of RES, BETA, CNA and HONE but autoclave sterilization did not have any effect on load-de fl ection characteristics of most of the -titanium wires tested, indicating that clinicians who want to provide maximum safety for their The sterilization effect is achieved through the action of a forced circulation of dry hot air subject to a specified temperature and sterilization exposure time. Usually, a temperature of 160°C or 180°C is applied during the sterilization exposure time, which ranges from 30 – 60 minutes, depending on the nature of use.
