Abstract

The release of elements that are used in dental alloys to provide mechanical and physical properties is known to be biologically harmful. The increased use of base metal alloys composed of active metals rather than noble metal alloys for many reasons, has resulted in an increase of studies on this subject. For this purpose, the in vitro evaluation of the release of the elements from six base metal (Ni-Cr and Co-Cr) and two noble metal alloys is aimed in our study. Ten samples from each alloy which is 5 mm in diameter and 2 mm in thickness was prepared. Five of each samples was polished using clinical technique and other five were left sandblasted. The alloys were incubated for thirty days in conditions of 37° C, 5 % CO2, 95 % humidity and pH of 7,4 using Dulbecco's Modified Eagle's Medium. As a control group, cell culture medium without alloy samples under same conditions has been used. The element release of the alloys left in the cell culture medium and the element amount seen in the control culture medium for thirty days was evaluated quantitatively using AAS. More element release was seen in base metal (Ni-Cr and Co-Cr) alloys than noble metal alloys as it is with sandblasted alloys than polished alloys.

Özet

Diş hekimliğinde kullanılan dental döküm alaşımlarından, mekanik ve fizik özellikleri kazandırmak üzere katılan ve biyolojik olarak zararlı olabilecek elementlerin, salınımı dikkatleri çekmektedir. Çeşitli nedenlerle soy metal alaşımları yerine, aktif metaller içeren temel metal alaşımlarının kullanımındaki artış, bu konudaki çalışmaların çoğalmasına neden olmuştur. Bu amaçla çalışmamızda, altı temel metal (Ni-C/ ve Co-Cr) ve iki soy metal alaşımlarından element salımınının in vitro olarak değerlendirmek amaçlanmıştır. Her bir alaşımdan 5mm çapında ve 2mm kalınlığında disk şeklinde hazırlanmış olan on örneğin, beş tanesine klinik olarak kullanılan tekniklere uygun parlatma işlemi yapılırken, diğer beşi kumlanmış olarak bırakılmıştır. Hazırlanan örnekler Dulbecco's Modified Eagle's Medium kültür vasatı kullanılarak, 37° C'de, % 5 CO2'li ve % 95 nemli ve pH'sı 7,4 olan ortamda otuz günlüğüne inkübe edilmiştir. Kontrol grubu olarak, aynı koşullar altında alaşım örnekleri olmayan hücre kültürü va-satı kullanılmıştır. Hücre kültürü vasatı içerisine otuz gün bırakılan alaşımlardan element salınımı ve kontrol vasatında bulunan elementlerin miktarları, AAS kullanılarak kantitatif olarak değerlendirilmiştir. Temel metal (Ni-Cr ve Co-Cr) alaşımlarından, soy metal alaşımlarına göre ve kumlanmış alaşımlardan, parlatılmış alaşımlara göre daha fazla element salınımı tespit edilmiştir.
