Perception of risk of HIV infection from regular attenders to an industrial dental service.

The advent of the HIV pandemic has necessitated the introduction of consistent cross-infection procedures for dentistry. Suprisingly little is known of patient reactions to some of these changes. A structured questionnaire was administered (in 1988/9, n = 613) to regular-attending patients of an industrial dental service to assess their views towards cross-infection procedures. Approximately a third of the study sample believed that there was a slight risk or more of contracting HIV infection at the dentist. This risk perception attenuated with further visits to the dentist. Some patients (13%) claimed to be aware from the media of someone having been cross-infected with the HIV virus from a dental visit. The majority of patients prefer the dentist to adopt the barrier methods of mask and glove wearing. Over 60% of patients would like their dentist to wear a mask when in fact a mask had not been worn. Accuracy of recall by patients for mask wearing was only 70% and for glove wearing 88%. The possibility that drawing the patient's attention to cross-infection control may be reassuring for the patient was not supported with some evidence to suggest that in instances where the dentist provided treatment, the patient's perception of risk was increased.
