Abstract (2. Language): 
Purpose: In our invivo study for evaluating the effect of amalgam as coronal or retrograde fillings, on transferring mercury to body fluids like blood and urine. We also investigated the effect of mastication on this subject. Material and Methods: In our study we used 24 adult mongrel dogs To evaluate the presence of mercury in blood we used atomic absorption spectrophotometer technique; in urine we used Lindstedt technique. Results: After the fist week between control and groups 1 and 2 there were significant difference. At urine Hg levels between all the groups there were no significant difference. Conclusion: According to our findings, regardless of the fact that the teeth is in mastication or not, amalgam cavity fillings causes a transfer of mercury to blood and urine. At the first week of the amalgam placement the mercury levels reaches their highest level which decreases with time. However a single retrograde filling don't have an effect like this.

Abstract (Original Language): 
Amaç: Bu invivo çalışmada amalgam dolgu varlığını ve dolgulu dişlerin çiğneme fonksiyonuna girip girmemesi gibi faktörlerin, kan idrar gibi vücut sıvılarına civa geçişini ne şekilde etkilediğini, ayrıca retrograd amalgam dolgulardan kan ve idrara civa geçişi olup olmadığını inceledik. Gereç ve Yöntem: Bu çalışma, İ.Ü. Veteriner Fakültesi İçhastalıkları Anabilim Dalı Kliniği'nde, yaş ortalaması 4(±2) olan, melez 24 adet erişkin erkek köpek üzerinde gerçekleştirilmiştir. Deneklerden alınan kan örneklerinde civa tayini atomik absorbsiyon spektrofotometresinde hidrür sistemi, idrar örneklerinde civanın saptanmasında Lindstedt yöntemi ile yapılmıştır. Bulgular: Kontrol grubuna oranla, retrograd dolgu bulunan deneklerde daha yüksek kan civa seviyesine rastlanmıştır. Buna karşılık idrar Hg seviyeleri açısından tüm dönemlerde her iki grup arasında istatistiksel olarak anlamlı bir fark bulunmamıştır Sonuç: Çalışmamızın sonunda amalgam dolgulardan; çiğneme fonksiyonuna girsin girmesin; vücut sıvılarına civa geçişinin oldugunu, bunun zamanla azalmakla beraber en yüksek 1. haftada olduğunu, ancak tek bir retrograd dolgunun istatistiksel olarak kan ve idrardaki civa seviyesini etkilemediği so¬nucuna vardık.
