Objective: To analyze the actual situation of oral comprehensive treatment table water channel after disinfection by hypochlorous acid disinfectant. Methods: Select the first 6 oral comprehensive treatment tables in our hospital in 2018 without hypochlorous acid disinfection equipment in the waterway and 6 oral comprehensive treatment tables with hypochlorous acid disinfection equipment in the waterway after 2018. The first 6 oral comprehensive treatment tables in 2018 were selected. The waterway without hypochlorous acid disinfection equipment was set as the control group. After 2018, the waterway of the 6 dental comprehensive treatment stations equipped with hypochlorous acid disinfection equipment was set as the observation group, and the total number of colonies, microbial species and opportunistic pathogens were compared between the two groups. Results: The observation group did not find that the total number of colonies decreased significantly after the installation of hypochlorous acid disinfection equipment, and the difference was significant (P<0.05), which was statistically significant. Pseudomonas aeruginosa, Escherichia coli and Legionella pneumophila were detected in the control group. The water samples were detected as Pseudomonas fluorescens, Bordetella bronchiseptica, Balloon urethra, Acinetobacter calcium acetate baumannii, Acinetobacter rouge/A. Alcaligenes. Pseudomonas stutzeri and Brevimonas vesicularis were detected in the observation group. Pseudomonas aeruginosa, Escherichia coli, and Legionella pneumophila were not detected. Conclusion: There is microbial contamination in the waterway of the oral comprehensive treatment table, and the risk of infection is high. Disinfection with hypochlorous acid disinfectant can reduce microorganisms and reduce the risk of nosocomial infection, which is worthy of clinical attention.
