Pneumoconiosis identified by HRCT was present in almost half of DPTs surveyed. Appropriate education and workplace protection should be given to DPTs in order to prevent exposure to hazardous materials in dental prosthetics laboratories.

In this study we investigated the level of knowledge and ideas of the university students and staff, about the last stage of Tobacco Law No. 5727, which came into force on 19 July 2009 in our country. This is descriptive questionnaire survey. Study's universe was consisting of the students 2009-2010 academic year studying in our universities and academic and administrative staff. A total of 2271 people were included the study. In our study, smoking prevalence was 21.3%. The prevalence for narghile smoking as 4.8% was the highest among students. 94.9% of participants thought that passive smoking increased the risk for human health. Asked whether the banned places, the most correct answers were; the school (97.0%), bank branches (96.3%) and hospitals (96.2%) as the most incorrect answers were; in the garden of hospital (55.7%), garden of private education (53.4%) and the school playground (46.1%). 87.6% of the participants were supporting the new tobacco law. 61.3% of smokers were supporting the law (p= 0.000). 54.3% of narghile-smokers support the law, and this rate was lower than cigarette smokers. Overall, tobacco law is known and supported between our students and staff. More information and supervision should be given about the banned places like school garden and private course gardens which were the high rate of false knowledge. The support to law among students is lower than staff. Similarly narghile use among students is often more. The community should be informed also about the other tobacco products.
