SKIN PROBLEMS AMONG DANISH DENTAL-TECHNICIANS - A CROSS-SECTIONAL STUDY

Our objective was to evaluate changes in the prevalence of skin problems on the hands among dental technicians during the last 10 years by comparison with results of a previous study, to study whether the presence and location of skin problems could be related to work with acrylates, and to study whether the use of gloves had any influence on the prevalence of the skin problems. A cross-sectional questionnaire study among 192 dental technicians at work was performed using an expanded version of a questionnaire from a Danish survey 10 years ago. The cumulative prevalence of skin problems on the hands was 53%. The 1-year prevalence of skin problems on the hands was 43%. The point prevalence of skin problems on the hands was 36%. These prevalence figures were profoundly higher than the figures reported for the general population, and the figures did not differ from those obtained in the study 10 years ago. The point prevalence of skin problems on the hands among individuals handling acrylates was 38% higher than among individuals who never worked with acrylates. No difference in the occurrence of skin problems was observed between individuals using gloves and individuals who did not use gloves while handling acrylates. The prevalence difference of skin problems on the fingertips was 7.3% between individuals handling acrylates daily or several times a week and individuals handling acrylates less frequently. The present study reveals that working as a dental technician is associated with an increased risk of developing skin problems on the hands compared with the general population, This risk has not decreased during the last 10 years.
