Objective: To determine the prevalence of latex allergy in dental workers.

Design: Questionnaire survey of staff of a dental school.

Setting: The Westmead Dental School, a large dental facility in western Sydney.

Participants: 230 staff members of the Westmead Dental School (consisting of general and specialist dentists, chairside assistants and registered nurses, laboratory technicians, dental therapists and hygienists) received questionnaires.

Main outcome measures: The prevalence of latex allergy, defined by prompt onset of hand urticaria with or without generalised symptoms, and the prevalence of hand dermatitis and other glove-related symptoms. Also, the relationship between latex allergy and associated atopic status.

Results: 177 staff (77%) responded by the set collection date; 33% reported symptoms related to wearing gloves and 22% satisfied the criteria for glove dermatitis. Sixteen respondents (9%) reported characteristics suggestive of latex- glove allergy.

Conclusions: Confirmation of the 9% prevalence of latex allergy among dental workers will require further studies incorporating an objective measure of IgE-mediated hypersensitivity.
