Analyzing the occupational exposure risks of dental healthcare workers from the perspective of repeated occupational exposure.
Article in BMC health services research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundHealthcare workers in dental hospitals frequently experience repeated occupational exposures (ROEs). In our study, we aim to analyze these repeated exposures among dental healthcare workers (DHWs), assess the risk levels of different risk factors, and explore the significance of ROE data for infection control in dental hospitals.
methodsBased on hospital statistical data, we categorized the occupational exposure incidents at West China Hospital of Stomatology over the past seven years into initial and repeated exposures. We analyzed the association of various risk factors, including personnel types, gender, treatment locations, timing of occupational exposure, and pathways of occupational exposure, with the occurrence of repeated exposures. The Statistical Package for Social Sciences (SPSS) 21 was used to conduct chi-square analysis and binary logistic regression analysis, with the significance level set at p < 0.05.
resultsCompared to students, hospital dentists with teaching qualifications exhibited a higher risk of ROEs. The risk of repeated exposure for dental students was 60% lower than that of hospital dentists (P = 0.003). However, gender, treatment locations, timing of occupational exposure, and pathways of occupational exposure did not significantly impact the repeated exposures among DHWs.
conclusionsOur study demonstrates that the analysis of repeated occupational exposures (ROEs) is meaningful. In our study, hospital dentists with teaching qualifications had the highest risk of ROEs, compared to dental students, hospital dental nurses, and dental nurse students. This means that among individuals who have already experienced occupational exposure, hospital dentists are more likely to experience repeated exposure. Meanwhile, gender, treatment locations, timing of occupational exposure, and pathways of occupational exposure did not have a significant impact on the occurrence of ROEs.
