“…It is interesting to note that all the elements listed from their 30 lung samples could be detected in one of our patients (case l ) except for silver. Moreover, e lements not found by Morgenroth et al, 11 eg, mercury-based amalgam, were observed, again illustrating the very complex nature of inorganic dust exposure in this particular type of mechanical dentistry.…”

“…Although the risk of pneumoconiosis is well known, typical silicotic nodules were not seen in all cases of pneumoconiosis among dental technicians.5 25 Thus the pathogenesis of this lung disorder may be difficult to link to a single dust exposure. These dental technicians were self employed workers particularly at risk for occupational lung disease: most worked without ventilation for more than eight hours a day.…”

“…The studied population was, therefore, composed of three groups: 68 control workers 43-66 years old (group C); 71 dental technicians 43-68 years old (group D) for the comparisons of respiratory symptoms and lung function with group C; and 33 dental technicians younger than 43 (25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40)(41)(42) and one 75 years old (group d) to study the effect of duration of exposure by comparison with group D. QUESTIONNAIRES Each subject completed a questionnaire about individual characteristics such as age, height, medical history, smoking habits, occupational history. Nonsmokers were defined as those persons smoking less than one cigarette a day and ex-smokers as those who had stopped smoking completely at least six months before the study.…”

From the registry of self employed workers living in Paris, a group of 105 dental technicians was studied to evaluate occupational exposure, to determine respiratory manifestations, and to investigate immune disturbances. Seventy one dental technicians (age range 43-68: group D), 34 dental technicians younger than 43 or older than 68 (group d), and 68 control workers (age range 43-66: group C) were investigated. The demographic characteristics and the smoking habits of the groups D and C did not differ significantly. The dental technicians often worked alone (43.7%) or in small laboratories without adequate dust control. The mean duration of their exposure was long (group D 34*0 (SD 8-4) years). The prevalence of respiratory symptoms did not differ betwen groups D and C except for the occurrence of increased cough and phlegm lasting for three weeks or more over the past three years (group D 16-90/o, group C 2-9%/o, p < 0.007). The effect of cigarette smoking on respiratory symptoms and lung function was obvious. All mean values of lung function for dental technicians and controls were within normal limits. Significant decreases in all mean lung function values were found among smokers by comparison with non-smokers, however, and a positive interaction with occupational exposure was established.

“…Silica dust, aluminum oxide, asbestos fibers and various metals, such as cobalt, chromium, nickel, and beryllium which have been used to manufacture bridges, crowns and dentures, may induce lung fibrosis [7, 8]. Association between lung fibrosis and a specific causal agent is difficult to define because of the multivariate exposure of dental technicians [8].…”

Pneumoconiosis among Cretan Dental Technicians

et al. 1999

Pneumoconiosis among dental technicians has recently emerged as an area of research in interstitial lung disease. This study was carried out to estimate the prevalence of pneumoconiosis in Greek dental technicians on the island of Crete. Fifty-one of the 58 dental technicians of the Heraklion Dental Technicians’ Association completed an exposure history questionnaire and underwent a clinical examination, including chest radiographs, and spirometric assessment of lung volume and diffusing capacity. Values were compared with 51 control subjects. Five dental technicians showed radiological evidence of pneumoconiosis. Mean lung function values of the dental technicians, even in those with pneumoconiosis, were not significantly different from controls. No significant changes in lung function parameters were associated with smoking, exposure to metals and other contaminants. Dental technicians, however, reported more respiratory symptoms than controls (p = 0.008). Symptoms were associated to the absence of a ventilation system. We concluded that occupational exposure in dental technicians in Crete did not affect lung function. The prevalence of pneumoconiosis in this study was 9.8%.
