The aim of our study was to investigate occupational dust exposure, and to determine the frequency of respiratory function disorders and radiologic abnormalities among DLTs. MATERIALS AND METHODS: The study enrolled 94 DLTs who were exposed to dust in dental laboratories and 94 control subjects. Dust concentrations in the workplaces were measured. RESULTS: The mean age of DLTs was 30.70 +/- 9.84 years. No significant difference was found between the DLTs and the control groups for age or smoking status (p > 0.05). Spirometric values for the DLTs were found to be lower than the control group (p < 0.05). The mean working period for DLTs was 9.19 +/- 5.9 years. The pulmonary function test results for the DLTs showed that 65.9% had a normal pattern, 22.4% were restrictive, and 11.7% showed obstructive type pulmonary function disorder. Negative correlations were found between the working period time and Forced Expiratory Volume in 1 second in the DLTs (R = -0.675 p = 0.000). Negative correlations were also found between working period time and Forced Vital Capacity in the DLTs (R = -0.720 p = 0.000). All DLTs had chest X-rays and 16 (17%) of them showed radiological pneumoconiosis. CONCLUSIONS: This study showed a negative association between level of respiratory function and working period in DLTs.eninfo:eu-repo/semantics/closedAccessDental Laboratory TechniciansPneumoconiosisRespiratory FunctionArticle176809814WOS:0003252079000132-s2.0-8487857275823609365Q2Q4
