Prevalence of Occupational Contact Dermatitis Among Dental Personnel Using the Nordic Occupational Skin Questionnaire-2002: A Prospective Cross-Sectional Study

Background: Occupational skin disease (OSD), such as contact dermatitis, is widespread among dental professionals; however, reports regarding its prevalence have inconsistent findings and methodology. Therefore, we conducted a cross-sectional survey using a self-reported questionnaire to estimate the prevalence of work-related and occupational exposure-induced skin diseases. Methodology: A self-administered questionnaire, based on the validated Nordic Occupational Skin Questionnaire-2002, was distributed to 15 dental clinics in Israel in the first half of 2022. The questionnaire included questions about the occupation, exposure, and history of atopic disease, dry skin, and hand/arm and wrist eczema, as well as participant demographics. Results: Overall, 312 dental professionals completed the questionnaires. Response rate was 80%. The lifetime prevalence of self-reported skin symptoms was 19.23%. Significant risk factors included exposure to metal objects, odds ratio (OR): 2.43, 95% confidence interval (CI): [1.02, 5.78]; p <.05, dry skin (OR: 3.54, 95% CI: [1.93, 6.5]; p <.001), itching when sweating (OR: 2.89, 95% CI: [1.39, 6]; p <.05), contact urticaria (OR: 10.67, 95% CI: [4.46, 25.49]; p <.001), hay fever (OR: 2.25, 95% CI: [1.14, 4.42]; p <.05), allergic symptoms (OR; 2.33, 95% CI: [1.18, 4.58]; p <.05), and asthma (OR: 4.8, 95% CI: [2.17, 10.36]; p <.001). Conclusions: This is the first study to use the NOSQ-2002 among dental professionals. Our study provides a better understanding of the prevalence and consequences of OSDs among dental personnel by utilizing the validated tool NOSQ-2002.
