Background:
The prevalence of latex allergy among dental patients is not known, although it has been increasing in the population since 1982, when the use of gloves was expanded to prevent the transmission of infectious diseases.
Methods:
A retrospective cross-sectional study was undertaken of 1,798 electronic health records (EHRs) of new clinic patients who registered at the University of Pittsburgh School of Dental Medicine (SDM) dental clinic between January and June 2010. Data extracted from the EHRs included age, gender, and a history of a previous latex reaction, asthma, or allergy to penicillin.
Results:
A previous reaction to latex was reported by 59 patients (3.3%). Women were almost three times more likely to report this (4.7% versus 1.6%, P = 0.0005). Histories of asthma or penicillin allergy in women were significantly associated with latex allergy (P = 0.0005 and P = 0.0001, respectively).
Conclusions:
The reported rate of a previous reaction to latex in this patient sample was higher than that of the general population. This may, in part, be related to repeated exposures to latex-containing gloves.
Clinical Implications:
Practitioners are increasingly likely to encounter patients who have had a reaction to latex. Non-latex products must be available for these patients, who are more likely to be women and individuals with asthma or an allergy to penicillin.
