SUMMARYThe relation between the extent of radiological findings and respiratory functions in pneumoconiosis cases of dental technicians who are working in Ankara The relation between the extent of radiological findings and respiratory functions İn pneumoconiosis cases of dental technicians who are working in Ankara 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 and Methods: 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 128 INTRODUCTIONDental laboratories harbor many dangers for dental technicians including physical, chemical, radioactive, ergonomic, psychological and biological ones. Dental technicians are constantly exposed to the vapor of different solvents and non organic acids, toxic gases formed during material use and to deleterious effects of dust formed during finishing, grinding and sandblasting of ceramic, acrylate and metal alloys (1-3). Pneumoconiosis, hypersensitivity pneumonia, occupational asthma and lung cancer may occur in dental technicians depending upon the duration of exposure (4).Dental technicians' pneumoconiosis (DTP), is a disease presenting with interstitial inflammation and fibrosis occurring due to exposure to complex substances (5). Although clinical functional parameters are influenced minimally in the early period of the disease, impairment in clinical functional parameters becomes more marked with radiological progression (6). In the evaluation of the severity of the disease, the employment of radiological and functional indices becomes more important (7).High resolution computerised tomography (HRCT) has an increasingly important role in the evaluation of occupational lung disease. HRCT is more sensitive than lung radiography in the detection of asbestosis, silicosis, pneumoconiosis and other parenchymal abnormalities in early period (8).In the literature, there are studies demonstrating the relation between the degree of involvement detected with lung radiography or HRCT and functional loss in various occupational groups (9,10). Although there are many studies showing the clinical findings, radiological involvement and functional impairment in dental technicians; relation between the degree of radiological involvement and functional impairment has not been clarified (11)(12)(13). In the present study with a large case series, the presence of a relation between radiological findings (chest X-Ray/HRCT) and functional findings in all dental technicians residing in Ankara, Turkey was evaluated. As far as we know, there is no previous study in the literature evaluating the relation between the extent of pulmonary involvement in lung graphies and functional findings and comparing lung radiogr...

Dental technician pneumoconiosis mimicking pulmonary tuberculosis: a case report

BackgroundDental laboratory technicians are at risk of developing occupational respiratory diseases due to exposure to various potentially toxic substances in their working environment. Since 1939, few cases of silicosis among dental technician have been reported.Case presentationWe illustrate a 38 year-old female, who worked in a dental laboratory for 20 years, initially treated as pulmonary tuberculosis and chronic necrotising aspergillosis without much improvement. Computed tomography guided lung biopsy and bronchoscopic transbronchial lung biopsy were performed. Lung tissue biopsies showed presence of refractile dental materials within the areas of histiocyte proliferation. The diagnosis of dental technician pneumoconiosis was obtained and our patient underwent pulmonary rehabilitation.ConclusionsThis case highlights the importance of obtaining a detailed occupational history in tuberculosis endemic area, as pulmonary tuberculosis is a great mimicker of other respiratory diseases.

“…Many experimental and epidemiological studies have proven the potential health hazards of metal, acrylic, and ceramic dust. [1][2][3][4][5][6] Exposure to metals in dental laboratories is not the only matter of concern when considering exposure to components of base metal alloys, but metals present in the refractory materials and abrasives used in all melting, and prostheses finishing must also be considered. Base metal alloys typically consist of 35% to 65% cobalt, 20% to 30% chrome, 0% to 30% nickel and molybdenum, and silica, beryllium, boron, and carbon in minor quantities.…”

“…Inhalation by dental technicians of dust containing free silica or silicon dioxide can lead to respiratory symptoms like silicosis. 4,5 The toxic risks of the substances used in the manufacturing of prostheses and other products within the dental laboratory are the result of either acute or chronic exposure to them. The effects of those risks have not yet been thoroughly assessed.…”

Purpose This is a cross‐sectional study to assess the incidence of micronuclei and other nuclear morphological changes in buccal epithelial cells of dental technicians. Materials and Methods The study was conducted on 45 dental technicians versus 2 control groups: 50 dentists and 50 dental assistants. DNA damage was analyzed in exfoliated buccal mucosa cells by micronucleus assay. The differences in the frequency of detected types of cytogenetic damage between experimental groups were analyzed by applying 2‐way ANOVA with Tukey's HSD post‐hoc test. Results Dentists and dental assistants have significantly lower incidence of micronucleated cells than technicians (mean ± SD: 0.68 ± 0.74, 0.58 ± 0.81, and 1.58 ± 2.07; p = 0.031 and p = 0.015, respectively), and this trend also holds for karyolitic cells (0.10 ± 0.30, 0.20 ± 0.49, and 1.42 ± 1.25; p < 0.001 and p < 0.001, respectively), condensed chromatin (0.16 ± 0.37, 0.14 ± 0.35, and 0.76 ± 0.98; p < 0.001 and p < 0.001, respectively), and pyknotic cells (0.04 ± 0.20, 0.08 ± 0.27, and 0.96 ± 1.24; p < 0.001 and p < 0.001, respectively). Conclusion Cytogenetic biomarkers in dental technician buccal mucosa are increased compared with control groups. This increase may be associated with more extensive exposure to potentially harmful components of the materials used in everyday dental practice.
