The articles about various pneumoconiosis in dental technicians who work in inconvenient conditions have been increasing in recent years. Exposure to dust and fume that occur during the dental procedure may play role in pneumoconiosis of dental technicians. A 53 years old male patient conveyed that he has worked in dental prosthesis procedures for 22 years (1968-1990).Environmental asbestosis was not established in the history of the case but there were calcified pleural plaques in the chest x-ray graphy.There were appearance of calcific asbest plaques in many section of thorax CT.A case of pneumoconiosis in dental technician who work in unadequate preventive conditions was reported in this paper. Probably ,exposure to the asbest fibers that occurs during the procedure of dental prosthesis were the main reason for developing calcific pleural lesions.

Dis teknisyeni pnömokonyozu kalsifiye plevral plak olusturabilir mi? (Bir olgu nedeniyle)

Öz

Son dönemlerde uygun olmayan kosullarda çalısan dis teknisyenlerinde çesitli pnömokonyozlar ile ilgili yayınlar artmaktadır. Protez islemleri esnasında ortaya çıkan çesitli toz ve duman maruziyeti, dis teknisyenleri pnömokonyozunda rol oynamaktadır. Yaklasık 22 yıl (1968-1990) dis teknisyeni olarak görev yapan 53 yasındaki erkek hasta, bütün protez islemlerinde görev yaptıgını tarif etti. Çevresel asbest teması saptanmayan olgunun akciger grafisinde kalsisifiye plevral plaklar saptandı. Toraks bilgisayarlı tomografide ise kalsifik asbest plaklarını düsündüren görünümler saptandı. Bu çalısmada korunma kosulları uygun olmayan laboratuarlarda çalısan dis teknisyeninde gelisen pnömokonyoz vakası bildirilmistir. Muhtemelen protez islemi esnasında ortaya salınan asbest liflerinin plevral plak olusturabilecegini düsündük.
