Abstract
The purpose of this study is to gather biofilm of unit chair waterline in the laboratory, to analyze microorganisms, to apply the existing draw-off method and the method of using disinfectant, and to compare the change of the number of microorganisms. The water was provided by the waterline of the unitchair, and the gathered samples were cultured with the use of R2A agar plate. Bacterial species separated through the identification of microorganisms were analyzed. To identify the decrease of microorganism for draw-off, samples were gathered in the intervals of 30 seconds, 60 seconds and 120 seconds, and to identify the effect of disinfectant, samples after disinfection were gathered. The quantitative comparison of microorganisms through the gathered samples was done by SPSS program. The number of identified bacteria are 8 species, most of which are gram-negative bacterium, and Sphingomonas type. The rapid decrease of the number of microorganism through draw-off for 60 seconds was confirmed, and microorganisms after disinfection weren't detected right away. Based on the method and result of this study, the water pipe of unit chair, which can be neglected easily, can be managed, so cross infection can be prevented, and systemic management can be possible.
