The scaler tips were inoculated with\n Escherichia coli<\/jats:italic>\n and\n Staphylococcus aureus<\/jats:italic>\n bacteria, following which the scalers in the control and test groups were subjected to conventional sterilization and argon plasma sterilization, respectively. Varying exposure times of plasma treatment were done on the test group samples to evaluate the minimum time required for complete sterilization. Subsequently, streaks were made on plate count agar using each of these instruments. The agar plates were then kept in an incubator for 24 h, following which bacterial colony count was assessed (colony-forming units\/mL). Furthermore, the scanning electron microscopic (SEM) view of the scaler tip was studied before and after plasma treatment.\n <\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n A complete elimination of bacterial load (Gram-positive as well as Gram-negative) from the instrument surface was achieved by the plasma exposure time of 15\u201320 s. SEM analysis did not show a significant difference before and after plasma treatment as not many organic residues were present on the scaler tip.<\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n Cold atmospheric pressure plasma is an efficient and time-saving method of sterilization, capable of destroying both Gram-positive and Gram-negative bacteria.<\/jats:p>\n
