FARKLI BİTİRME VE PARLATMA İŞLEMLERİNİN ÜÇ FARKLI RESİN MATERYALİN YÜZEY PÜRÜZLÜLÜĞÜ ÜZERİNE ETKİSİ

Öz

Amaç: Bitirme ve parlatma i lemleri, yap$lan restoras- yonun ömrünün uzat$lmas$nda önemli bir etkendir. Çal$ mam$z$n amac$ çe itli bitirme/parlatma sistemle- rinin, üç farkl$ resin materyalinin yüzey pürüzlülü;ü üzerine etkisini kar $la t$rmakt$r.Gereç ve Yöntem: Estetik restorasyon- larda kullan$lan 3 materyalden teflon kal$plar (8mm çap$nda 5mm yüksekli;inde) kullan$larak 54 adet disk örnek haz$rland$; Hibrit kompozit (Valux Plus), kondanse edilebilir kompozit (Alert), ormocer (Admira).Her bir materyalden 18 adet örnek haz$rland$ ve s$radan ekilde 3 gruba ayr$ld$. (n=6). Her gruba farkl$ bitirme/ parlatma sistemleri (Elmas bitirme frezleri, Sof-Lex diskleri, Astropol sistemi) uyguland$. Her örnek yüzeyinde Mitutoyo Surfcorder /SE-40D profilometre cihaz$ ile ortalama yüzey pürüzlülü;ü de;erleri (Ra) elde edildi ve veriler çift yönlü ANOVA ve Duncan testi ile de;erlendirildi. Bulgular ve Sonuç: Üç bitirme/cila sisteminin ortalama Ra de;erleri aras$ndaki fark önemli bulundu.(p
