The attitudes to cross-infection control of 800 dental laboratories registered with the Dental Laboratories Association have been surveyed. Considering the topicality of the subject material and the need for careful cross-infection control within and beyond the dental surgery, the response rate of 22% (175) was disappointingly low. As a result of the low response rate, the results should be seen as a guide only. Forty-nine percent of respondents had a cross-infection policy and of those with no policy 64% intended to implement one in the future. Thirty percent of laboratories receive known undisinfected work from the dental surgery. Of those items disinfected on arrival at the laboratory, those most frequently disinfected are dental impressions (77%) and dentures (51%). The most popular chemicals used for disinfection are household bleach, chlorhexidine and glutaraldehyde. Forty-four percent of the respondents generally (90% or more of the time) wear gloves when handling dental work received and opened in the laboratory. Seventy-four percent wear protective eye spectacles when trimming or polishing prostheses. Sixty-one percent used no disinfectant in the pumice and 93% did not disinfect the polishing instruments, eg wheels and mops. Forty-six percent had a policy for immunisation of staff against Hepatitis B.
