Effect of Repeated Sterilization Cycles on the Physical Properties of Scaling Instruments: A Scanning Electron Microscopy Study

摘要

Background:Repeated sterilizations cycles cause undesirable alterations in the material properties of the instruments, such as corrosion, alterations in the hardness of the metal and the loss of the cutting sharpness of the instrument. This research examined the effect of repeated dry heat sterilization and autoclaves cycles on carbon steel (CS) and stainless steel (SS) curettes during the scaling and root planning.
