MİKROSIZINTI ARAŞTIRMA TEKNİKLERİ VE MİKROSIZINTIYI ETKİLEYEN FAKTÖRLER

Abstract

Diþhekimliðinde mikrosýzýntý, birçok faktörebaðlý biyolojik bir fenomendir. Literatürde in vitromikrosýzýntý araþtýrma teknikleri ve bunlarýn güvenilirlikleri ve geçerlilikleri ile ilgili birçok veri bulunmaktadýr. Tamir dentini oluþumundaki biyolojik depozisyonu araþtýran veriler, dental materyallerin klinik seçimini etkileyen faktördür. Yapýlan son çalýþmalar,mikrosýzýntýyý önlemek için yeterli bir biyolojik týkamasaðlandýðýnda dentin ve pulpa iyileþmesinin gerçekleþtiðini göstermektedir. Bu çalýþmada, dentalrestorasyonlardaki mikrosýzýntýyý araþtýrmak için kullanýlan teknikler ve etkileyen faktörler sunulmuþtur.Bu teknikler içinde otoradyografik yöntem, elektrokimyasal yöntem, bakteriyel mikrosýzýntý yöntemi,insan serumu sýzýntýsý yöntemi, sývý filtrasyon tekniði,gazkromatografi yöntemi, boya sýzýntý yöntemi,kimyasal iþaretleyiciler, tarama elektron mikroskobuanalizleri, nötron aktivasyon analizi bulunmaktadýr.Etkileyen faktörler içinde ise termal siklus ve yüklemesiklusunun etkisi sunulmuþtur
