[Infection control in dental health care settings: results of a survey on current disinfection practices].

This study was performed to identify which disinfection procedures are currently used in dental offices and to evaluate staff knowledge regarding infection control. Information was collected by means of a questionnaire to which 226 subjects responded. Glutaraldehyde was found to be the most commonly used disinfectant for surfaces/drill units, handpieces and instruments; however, half of the respondents did not specify which disinfectants they used. Eighty-four percent of the respondents reported contact times, which in some cases were found to be insufficient; 43,4% stated that containers are washed and disinfected each time the disinfectant is replaced; 58.8% reported that dental handpieces and instruments are precleaned prior to sterilization while 73% believe that increased attention during performance of work practices could reduce the risk of infection. These findings suggest that dental health care personnel need to be better sensitized toward infection control measures and should be offered periodical training on the proper implementation of practice guidelines.
