Özet

Bu çalýþmanýn amacý, sabit ortodontik tedavilerde kullanýlan ark tellerinde bulunan Ni, Cr ve Coelementlerinin farklý pH ortamlarýndaki iyon salýnýmlarýnýn atomik absorbsiyon spektrofotometre ile deðerlendirilmesidir.Çalýþmada 3 cm uzunluðunda NiTi, paslanmazçelik, çok sarýmlý paslanmaz çelik ve TMA ark telleri,alt sað 1.molar bandý ve premolar braketine ligatüreedilerek benzer þartlar altýnda 4, 5.5 ve 7’lik pH' lardahazýrlanan yapay tükürük içinde bekletilmiþtir. 30. 60.ve 90. günlerde alýnan yapay tükürük örnekleri atomikabsorpsiyon spektrofotometre cihazýnda deðerlendirilmiþtir. Elde edilen veriler varyans ve çoklukarþýlaþtýrma analizleriyle karþýlaþtýrýlmýþtýr. Çalýþmanýn sonuçlarý, ark tellerinden en fazlaiyon salýnýmýnýn pH 4 seviyesinde olduðunu, iyonsalýnýmýnýn hýzýnýn üçüncü ayda en düþük düzeydeolduðu fakat salýnýmýn devam ettiðini göstermiþtir. Niiyonlarý en fazla salýnýmý gösterirken en az salýným Crelementinden olmuþtur
