Disinfection efficacy of different disinfectants on dental unit waterlines
摘要
Abstract
Objective To compare the disinfection efficacy of different disinfectants on dental unit waterlines (DUWLs). Methods 18 sets of DUWLs were randomly divided into 4 groups,and disinfected or treated with hydrogen peroxide (H2 O2 )disinfectant,sodium hypochlorite (NaClO)disinfectant,hydrogen peroxide silver ion disinfectant(Sanosil),and distilled water (DW)respectively.Water specimens from triple syringes and high-speed handpieces were taken,bacterial count before and after disinfection were compared.Results Before disinfection,no significant differences in bacterial counts were found among four groups (all P >0.05),bacterial counts of DUWLs of all groups severely exceeded the standard(all>3 000 CFU/mL).After disinfection,except DW group,bacterial counts of DUWLs of the other groups declined dramat-ically (all <100 CFU/mL),bacterial count after disinfection were all obviously lower than before disinfection (all P <0.001 ).One week after disinfection,bacterial counts among three disinfectant groups in different time periods were statisti-cally different (triple syringes:Day1—Day5,all P <0.05;high-speed handpieces:Day2,Day3 and Day5,all P <0.05). Day3 after disinfection of triple syringes by H2 O2 and NaClO,Day4 after disinfection of high-speed handpieces by H2 O2 and NaClO,and Day5 of triple syringes and high-speed handpieces by Sanosil all exceeded the standard of Center for Disease Control and Prevention of America.One week after disinfection,bacterial counts of three disinfection groups all exceeded or approximated to that before disinfection.Conclusion Three types of disinfectants can all effectively reduce bacterial load in DUWLs.Compared with other disinfectants,Sanosil has advantage of inhibiting bacterial growth after disinfection.关键词
