Comparison of antimicrobial effectsof someconventionaldisinfectantsina dentalsetting

Background: Since the dental treatment is directly associated with scattered blood and saliva, transmission of infections is a major problemin dental environment. Therefore, one of the requirements for infection control is sterilization and disinfection of surfaces and instruments usedin intervals amongpatients. This study aimed to evaluate the antibacterial activity of some disinfectants in the market, including micro10, phenol, ethanol and sodium hypochlorite on Staphylococcusaureus, Pseudomonas aeruginosa, Salmonella typhimurium and Candida albicans Methods: In this study agar diffusion and tube dilution methods were used. In agar diffusion method, each plate was divided in 6 sections, each related to a tested disinfectant. Totally 16 plates were applied. Also, in tube dilution method, 48 tubes were used and the specimens were cultured after 0, 5,15,30,60 minutes. To be reliability, each method repeated 8 times. Results: Among the selected disinfectants, the micro10 solution, especially its 5% concentration and deconex 5% were the most effective disinfectants; other disinfectants had also suitable antimicrobial effects except ethanol 70%, phenol 1% and 2% that were not effective against selected microorganism Conclusion: The results of our study showed that the micro10 disinfectant was more effective against common microorganisms in dental care settings compared to the other disinfectants.
