بررسی آلودگی با میکروب های هوازی وسایل فلزی قبل از استفاده در جراحی دهان

Infection control, in all surgery operations, is of high importance. Although a lot of advances have been made, but it is still necessary to observe methods for the prevention of spreading infection, especially for dentists who perform several minor surgeries in the office. As a result, investigating aerobic bacterial contamination of metal instruments, before application, should be paid special attention. The aim of this study was to investigate the aerobic bacterial contamination on metal instrument before oral surgery. Metal instruments, used in surgery and non surgery operations in 4 departments of dental faculty-oral and maxillofacial surgery, endodontics, periodontics, autoclave room with the sampling volume of 80 were selected randomly. After sterilization of all samples under specific conditions, they were transferred to microbiological laboratory of hygiene faculty and were cultured and incubated under 37° temperature for 24 hours. According to the results of culturing, just one case, affected with staphylococcus epidermis, was observed. Sterilization condition, in hygiene faculty, comparing to previous studies, shows 20% progress.
