Effect of Composite or Ceramic Thickness on the Polymerization Hardness of 5 Different Dual-cured Resin Luting Cements
Öz: Objective: The aim of the present study was to evaluate the influence of ceramic and composite thickness on polymerization hardness of five different dual-cure resin cements. Materials and Methods: A total of 100 disc-shaped spacer, 10-mm in diameter and five varying thicknesses (1.0mm, 2.0mm, 3.0mm, 4.0mm, 5.0mm) were fabricated from ceramic and composite materials. Dual-cure resin cement specimens with 8-mm diameter were prepared using metal brass mold and activated by light beneath the composite and ceramic disc shaped spacers. A total of 100 specimens of five different dual-cure resins (RelyX, Variolink, NX3, Calibra, Panavia F2.0) were prepared. Knoop hardness of each dual-cure resin cement was measured at five different point using a microhardness device with a 500 gm load, after 1 hr, 1 day, and 1 week polymerization. All data were statistically evaluated using one-way ANOVA. Results: Multivariate analysis of variance revealed significant differences in hardness of specimens dual-cured under composite resin or ceramic spacers and different time intervals (P<.001). Specimens cured through composite resin spacers showed less hardness values than ceramic spacers, with increasing thickness of the spacer. Also increasing the thickness of the composite or ceramic spacers produced a statistically significant decrease in microhardness of the dual-cure cements (P<.05). Conclusions: Hardness values significantly reduced when composite spacers were thicker than 2 mm and ceramic spacers thicker than 3 mm. Dual-cured resin cements are needed to be improved to achieve sufficient degree of hardening under composite and ceramic restorations. Different commercially available brands have different polymerization properties.
Anahtar Kelime: Kompozit veya Seramik Kalınlığının 5 Farklı Dual-Cure Resin Yapıştırıcı Simanın Polimerizasyon Sertliği Üzerine Etkisi
Öz: Amaç: Bu çalışmanın amacı, seramik ve kompozit kalınlığının beş farklı dual-cure rezin simanının polimerizasyon sertliği üzerindeki etkisini değerlendirmektir. Gereç ve Yöntemler: Seramik ve kompozit malzemelerden, 10 mm çapında ve beş farklı kalınlıkta (1.0 mm, 2.0 mm, 3.0 mm, 4.0 mm, 5.0 mm) toplam 100 adet disk şeklinde örnek hazırlanmıştır. 8 mm çapında dual-cure rezin siman numuneleri metal pirinç kalıp kullanılarak hazırlanmış ve kompozit ve seramik disk şeklindeki örnekler altında ışıkla polimerize edilmiştir. Beş farklı dual-cure rezin simandan (RelyX Universal, Variolink DC, NX3, Calibra Universal, Panavia F2.0) toplam 100 numune hazırlanmıştır. Her bir dual-cure rezin simanın Knoop sertlik değerleri, polimerizasyondan 1 saat, 1 gün ve 1 hafta sonra, 500 gr kuvvet uygulayan mikrosertlik ölçüm cihazı ile 5 farklı noktadan ölçülerek elde edilmiştir. Tüm veriler tek yönlü ANOVA kullanılarak istatistiksel olarak değerlendirilmiştir. Bulgular: Çok değişkenli varyans analizi, kompozit veya porselen örnekler altında polimerize edilen dual-cure rezin simanların sertliklerinde, farklı zaman aralıklarında ölçüldüklerinde önemli farklılıklar olduğunu ortaya çıkarmıştır. Kompozit örnekler altındaki dual-cure rezin simanların, kalınlık arttıkça seramik örnekler altındaki dual cure rezin simanlara göre sertlik değerinin daha düşük olduğu gözlenmiştir. Ayrıca, kompozit veya seramik örneklerin kalınlığı arttıkça dual-cure rezin simanların mikrosertlik değerlerinde istatistiksel olarak anlamlı bir azalma olmuştur. Kompozit örnekler 2 mm'den kalın olduğunda ve porselen örnekler 3 mm'den kalın olduğunda sertlik değerleri önemli ölçüde azalmıştır. Sonuçlar: Kompozit ve seramik restorasyonlar altında yeterli derecede sertleşme elde etmek için dual-cure rezin simanların iyileştirilmesi gerekmektedir. Piyasada bulunan markaların polimerizasyon özellikleri birbirinden farklıdır.
