FARKLI KONSANTRASYONLARDAKİ POVİDON İYOTUN HİBRİT CAD/CAM MATERYALİNİN RENK STABİLİTESİNE ETKİSİ

Amaç: Bu çalışmanın amacı, farklı konsantrasyonlardaki povidon iyot solüsyonlarının hibrit seramik CAD/CAM materyalinin renk stabilitesine etkisinin incelenmesidir. Gereç ve Yöntem: Çalışmada 2M2 rengine sahip Cerasmart (GC Corporation, Tokyo, Japonya) hibrit seramik bilgisayar destekli tasarım/bilgisayar destekli üretim (CAD/CAM) bloklarından 1,5x12x12mm boyutunda 60 adet kesit elde edildi. Örneklerin başlangıç renk değerleri spektrofotometre cihazı ile CIE L*a*b* sistemine göre ölçüldü. Örnekler 24 saat süreyle bekletilecekleri solüsyonlara göre rastgele 3 gruba ayrıldı (n=20). Grup 1 kontrol grubu olarak belirlendi ve örnekler distile suda bekletildi. Grup 2’de örnekler %0,25’lik povidon iyot solüsyonunda bekletildi. Grup 3’de ise örnekler %2,5’lik povidon iyot solüsyonunda bekletildi. Örnekler temizlendi ve renk değerleri tekrar ölçüldü. Renk değişim miktarları ΔE cinsinden hesaplandı. Elde edilen verilerin istatistiksel analizi Kruskal-Wallis testi ile yapıldı. Bulgular: Poivdon iyot solüsyonunda bekletilen örneklerde anlamlı derecede yüksek ΔE değerleri elde edildi (P<0.05). %2,5’lik povidon iyot grubu %0.25’lik povidon iyot grubuna göre anlamlı derecede daha yüksek ΔE değerleri gösterdi (P<0.05). %0,25’lik povidon iyot solüsyon grubunda elde edilen renk değişimi klinik olarak kabul edilebilir bulundu. Sonuçlar: Povidon iyot solüsyonu rezin seramik CAD/CAM materyali üzerinde renk değişimine neden olmaktadır. Povidon iyotun daha yüksek konsantrasyonunda daha fazla renk değişimi izlenmektedir.
