ABSTRACT
INTRODUCTION:
In dental technicians, parenchymal changes caused by dust affect pulmonary functions. The evaluation of the relation between radiological scores (chest X-Ray/HRCT) indicating the extent of pulmonary involvement and the severity of functional findings in dental technicians. MATERIALS ANDMETHODS:
440 dental technicians were evaluated with chest X-Ray, pulmonary function tests (PFTs) and high resolution computed tomography (HRCT). The degree of pulmonary involvement in radiological images was categorized based upon emphysema, the profusion of opacities, ground-glass opacity, honey combing and extent of pleural abnormalities.RESULT:
Mean age of the study population was 34.7 ± 8.5 and mean duration of work was 16.5 ± 7.9 years. The prevalance of Dental technicians' pneumoconiosis (DTP) was 11.1%. The most common opacity in HRCT was round opacity with a rate of 89.7%. The rate of large opacity was %14.3. There was positive correlation between ILO score and HRCT score. Negative correlation was found between ILO and HRCT scores and all pulmonary function tests (except for FEV1/FVC), while no relation was found with age, overall duration of exposure, smoking and the age ofwork onset. In Multiple regression analysis, the extent of pulmonary involvement (HRCT scores) was found to be an independent predictor of functional impairment. Functional parameter reflecting the extent of pulmonary involvement most accurately was (FEV1%).CONCLUSIONS:
It is our suggestion that radiological measurement should be used along with functional measurements in the evaluation of functional impairment in mixed dust exposed dental technicians.
