Abstract (2. Language): 
In this study 40 freshly extracted single rooted human maxillary teeth used. Root canal preparations made on every single tooth, and teeth filled with zincphosphate cement by using lateral condensation technique. Apical 2-3 millimetres of each tooth been cut and. standardized retrograde cavities prepared. Fifteen retrograde cavities contaminate with blood and cavities filled immediately, Fifteen cavities did not contaminate with blood and dry cavities filled with same kind of amalgam. Rest of the 10 teeth, 5 used as negative control group and 5 as positive control group. Root surfaces coated twice with nail vanish. All teeth waited on 37 v C lor 72 hours in 2 % methylene blue solution. Later all the teeth sectioned longitudinally. Lineer dye penetrations measured. Measurements in two groups compared with Student's t Test. Dye penetration on blood contaminate cavities were significantly less than dry cavities. Mean difference is 0,35 mm. (1=3.08; n-2=28; p<0.005). These differences may be occurs due to the blood by filling of the dentinal tubuluses and given less permission of dye penetration.

Abstract (Original Language): 
Bu araştırmada yeni çekilmiş 40 adet tek köklü üst çene insan dişi kullanılmıştır. Herbir dişin kanalları hazırlandıktan sonra lateral kondensasyon tekniği kullanılarak çinko fosfat simamyla dolduruldu. Her dişin apikal 2-3 mmJik kısmı kesildikten sonra kök ucu kaviteleri standard olarak hazırlandı. 15 kök ucu kavilesi insan kanıyla konîamine edildikten sonra hemen anında, 15 kavite ise kan h ulaştın İmadan kuru olarak aynı cins amalgamla retrograd olarak doldurulur. Kalan 10 dişin 5'i negatif konim, 5'i pozitifg kontrol olarak kullanıldı. Kök yüzeyleri İki kat tırnak cilası ile kaplandı. Hazırlanan dişler 72 saat müddetle %2'îik metilen mavisi içinde etüvde 37oC bekletildi. Daha sonra dişler longutidinal olarak kesildi. Boya sızıntı miktarları lineer olarak ölçüldü. Her iki grupta yapılan ölçümler Student t l eşti ile mukayese edildi. Kanla bulaşmış retrograd kavitelerde, kanla bulaşmamış retrograd kavitelere nazaran sızıntı anlamlı Ölçüde daha az bulundu. Ortalama fark 0.35 rnmJdir (T=3.08; n-2= 28; p<0.ÛÜ5). Bu farklılık kanla bulaşmış kavitelerde kanın denlin tubuluslanm tıkayarak boya geçişine daha az izin vermiş olmasından kaynaklanmış olabilir
