DISINFECTION OF ORTHODONTIC PLIERS USING THREE DIFFERENT DISINFECTANTS
Journal Title: Journal of International Dental and Medical Research - Year 2014, Vol 7, Issue 1
Abstract
In orthodontics effective disinfection of pliers in short time is important. We aimed to evaluate the effectiveness of three disinfectant solutions (two quaternary ammonium compounds (Deconex, Micro10+) and one hydrogen peroxide disinfectant (Sanosil)) in orthodontic pliers’ disinfection. Nine Adams pliers were sterilized with autoclave. Pliers were contaminated with standard and hospital staphylococus aureus and pseudomonas aeroginosa. After rinsing, pliers were immersed in assigned disinfectants. Immersion times were at 5, 10, and 15 min. Pliers were rinsed and shaken in sterile physiologic serum to bacteria elimination. Neither negative control group was submitted to disinfection process, nor positive control to any contamination processes. Samples were transferred to culture medium and colony count was done after 24 hours incubation. Culture results of positive control group were negative while in the negative control large number of colonies was appeared. Regardless type of bacteria, in 5 and 10 min effective decontamination order was: Sanosil>Deconex>Micro10+. In 15 min, results of three disinfectants were not significantly different. All disinfectants reduced bacteria significantly, even with 5min immersion. Antimicrobial activity was elevated by increasing exposure time. The disinfectant containing hydrogen peroxide and silver ion (Sanosil) showed greater activity than QACs (Micro10+ and Deconex).
