摘要

Background

As there has not been a comprehensive systematic review on the prevalence of contact dermatitis in dental professionals, the aim of this study is to determine the global prevalence of occupational contact dermatitis (OCD) and occupational skin diseases (OSD) in dental professionals.

Methods

In this meta-analysis, a search in databases including web of sciences, PubMed and Scopus was conducted until June 14, 2024. Google Scholar was examined to find relevant studies. The retrieved articles were screened and the necessary data were extracted from related articles and entered into the analysis. To evaluate the methodological quality of the included studies (risk of bias), the Newcastle–Ottawa Quality Assessment Scale, adapted for cross-sectional and cohort studies was used.

Results

In conducting a meta-analysis of articles related to OSD and OCD, heterogeneity and publication bias were observed. The results showed that the prevalence of OCD among dental professionals is 34% (95%CI = 28–41%, chi square = 1859, df = 32, I-square = 98.3%, p < 0.001). The results of meta-analysis showed that the prevalence of OSD is 30% (95%CI = 27–33%, chi square = 1286, df = 44, I-square = 96.6%, p < 0.001).

Conclusion

The results revealed that the global prevalence of OCD and OSD in the dental staff is over 30%, which is a relatively high. Among different subgroups, the highest prevalence was observed among dental technicians, followed by dental assistants. Dentists and dental hygienists had a lower-than-average prevalence in OCD and OSD. Routine screening of skin problems in dental professionals are recommended.
