Abstract

The release of elements that are used in dental alloys is known to be biologically harmful. The evaluation of the biocompatibility of dental materials is on systemic and local toxicity, allergenity, mutagenity and carcinogenity and recently focussed on the local effects of dental alloys, f n cytotoxicity evaluations, in vitro studies of cell cultures with cell lines that are directly in contact, usual}}' cell organells and their junctions is focused on. The decreased activity of the intracellular energy, effects the function of the cellular structures. For this purpose, the effects of six base metal (Ni-Cr and Co-Cr) and two noble metal alloys on mitotic activity in cellular 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 were polished using clinical technique and other Jive were left sandblasted. The alloys were incubated for 120 hours in conditions of 37°C, 5 % CO2, 95 % humidity and p H of 7,4 using Dulbecco's Modified Eagle's Medium in direct contact with monolayer human embryonal fibroblasts cell lines. As a control group, cell lines without alloy samples under same conditions has been used. Using immunocytochemical techniques, mitotic activity were examined with Zeiss LSM-51Ü confocal microscope (Germany). No difference in mitotic activity between polished and sandblasted alloys was seen but cells that are in contact with base metal (Ni-Cr and Co-Cr) and noble metal alloys showed less mitotic cells compared to the control group.

Özet

Diş hekimliğinde kullanılan dental döküm alaşımlarından, biyolojik olarak zararlı olabilecek elementlerin salınımı dikkatleri çekmektedir. Dental materyallerin biyouyumluluk değerlendirmeleri, sistemik ve lokal toksisite, allerji, mutajenite ve karsinojenite incelemeleri ile yapılmakla beraber, son zamanda, araştırmalar dental alaşımların lokal etkileri üzerine yoğunlaşmıştır. Sitotoksisite incelemelerinde, hücre dizilerinin alaşımlarla direkt temasta olduğu hücre kültürü ortamlarında in vitro yürütülen çalışmalarda hücre organelleri ve fonksiyonları üzerinde durulmaktadır. Hücre içi enerji aklivitesindeki azalma, hücresel yapıların fonksiyonunu etkiler. Bu amaçla çalışmamızda, altı temel metal (Ni-Cr ve Co-Cr) ve iki soy metal alaşımının hücre düzeyinde mitotik aktivite üzerine olan etkilerini, in vitro olarak değerlendirmek amaçlanmıştır. Her bir alaşımdan 5 mm çapında ve 2 mm kalınlığında disk şeklinde hazırlanmış olan on örneğin, beş tanesine klinik olarak kullanılan tekniklere uygun parlatma işlemi yapılırken, diğer beşi kumlanmış olarak bırakılmıştır. Alaşımlar ve tek sıralı insan embriyonel fibroblast hücre dizileri direkt temasta olacak şekilde, Dulbecco's Modified Eagle's Medium kültür vasatı kullanılarak, 37°C'de, % 5 CO,'li ve % 95 nemli ve pH'sı 7,4 olan ortamda. 120 saatliğine inkübe edilmiştir. Kontrol grubu olarak, aynı koşullar altında alaşım örnekleri olmayan hücre dizileri kullanılmıştır. Mıtotik aktivite immünositokimyasal yöntemler kullanılarak, Zeiss LSM510 konfokal mikroskop (Germany) ile incelenmiştir. Mitotik aktivite bakımından, parlatılmış ve kumlanmış alaşımlar arasında farklılık yokken, temel metal (Ni-Cr ve Co-Cr) ve soy metal alaşımları ile temasta kalan hücrelerde kontrol gruplarına göre daha az mitotik hücre olduğu gözlenmiştir.
