AIM: The purpose of this study was to investigate the microbial contamination in hand-operated and automatic radiographic solutions and on contact surfaces during radiographic procedures such as X-ray cone and button and surface of hand-operated and automatic radiographic solution tanks in dental clinics.
METHODS: A 10 mL liquid solution was taken with syringe at 5, 10, 24, and 48 hour time intervals from freshly prepared hand-operated and automatic processing solution. The swab samples were taken from the surfaces of radiographic solution tanks, X-ray cone and its button. The specimens were inoculated into blood agar and Eosin Methylene-Blue (EMB) agar. The plates were incubated in an incubator for 48 hours at 37 °C. Becton Dickinson Phoenix Automated Microbiology System was used for determining the microorganisms.
RESULTS: Although the microbiologic analyses of the samples revealed no microbial growth in the hand-operated and automatic radiographic solutions in all observation periods, the microbial growth on the contact surfaces was observed. Staphylococcus epidermidis, metisillin resistant from the surface of radiographic solution tanks, X-ray cone and switch. Streptococcus mitis was found on the X-ray switch.
CONCLUSION: Radiographic procedures can cause cross contamination; clinicians should therefore apply disinfection protocols in all radiographic procedures.
